How to Hire Employees in Maryland

The first-hire compliance sequence, in the order the work actually happens

The first time I helped a founder put someone on payroll in Maryland, we registered with the Comptroller, got the account number back, and assumed the state was handled. It was not. Maryland splits the employer registration across two agencies, and the second one, the Department of Labor, had no record of the business at all. We found out three weeks in.

That is the shape of hiring in Maryland. Nothing here is exotic. The rules are simply spread across more desks than a founder expects, and each one has its own clock. Coverage that has to exist before the first shift. A written notice that has to be handed over at the time of hiring. A local income tax that follows the employee home instead of staying at your office.

This guide runs the sequence in the order the work actually happens, from the federal EIN through the ninetieth day. It is written for owners and operators doing this without a dedicated HR person, which is the same reason I built FirstHR: the failure mode at this size is never ignorance of the rule, it is the rule arriving on a week when three other things are on fire.

TL;DR
Hiring in Maryland takes ten steps. Register for withholding with the Comptroller and separately for unemployment insurance with Maryland Labor, complete Form I-9 by the third business day, collect Form W-4 and Form MWH, give written notice of pay and leave at hire, file the new hire report within 20 days, and bind workers compensation before the first shift.

Maryland Hiring at a Glance: Every Step and Its Clock

Here is the whole sequence with the deadline attached to each step. Read it once before you start, because several of these steps have to be finished before the new hire walks in the door, not after.

The rest of this guide takes each step in turn, with the Maryland agency that owns it and the detail that trips up first-time employers. If this is your first hire anywhere, the general playbook for hiring your first employee covers the parts that are not state-specific.

Step 1: Get Your Federal EIN Before Anything Else

The federal Employer Identification Number is the prerequisite for both Maryland registrations, so it goes first. You apply online with the IRS, the application takes minutes, and the number is issued immediately during the session. Every state form after this one asks for it.

If you already have an EIN from forming the entity, reuse it. If you have been operating as a sole proprietor with no employees and filing under your Social Security number, you need an EIN now, because payroll tax reporting cannot run on an SSN. Getting this out of the way first saves a week of stalled state registrations later.

Step 2: Register for Maryland Withholding With the Comptroller

The Comptroller of Maryland issues your employer withholding account through the Combined Registration Application. New businesses file the application through Maryland Business Express, and new or existing businesses can register and make updates through the Maryland Tax Connect portal. The same application also covers a sales and use tax license and several other accounts if your business needs them.

What comes back is a Central Registration Number, which is the identifier you use for state withholding filings. Do this before the first wage payment. Without it you have no way to remit the state and county income tax you are legally required to withhold from that paycheck.

Definition
Combined Registration Application (CRA)
The single Comptroller of Maryland application that opens an employer withholding account and, depending on what you select, a sales and use tax license and other business tax accounts. It is filed online through Maryland Business Express or Maryland Tax Connect. Important limit: the CRA does not open your unemployment insurance account, which is a separate registration with a separate agency.

Maryland withholding is heavier than a flat state tax because of the local layer. Every Maryland county and Baltimore City levies a local income tax that you withhold alongside the state tax and remit together to the Comptroller. The county rate is driven by where the employee lives, which means the address you collect at hire is a payroll input, not just a personnel record. The Maryland payroll setup is worth reading in full before your first run.

Step 3: Open Your Unemployment Insurance Account With Maryland Labor

This is the registration founders miss. The Maryland Department of Labor, Division of Unemployment Insurance, defines an employer as a person or governmental entity who employs at least one person within the state. One hire makes you an employer. You register through the employer side of the BEACON portal, where you select the option to register an account and follow the prompts.

The numbers behind that account matter for your budget. Maryland taxes the first $8,500 earned by each employee in a calendar year. Tax Table A is in effect for 2026, the same table used for 2025, and it is the lowest of the six tables the state can run. Contributory employer rates under Table A range from 0.30% to 7.50%, with 7.50% as the standard rate. New employers land between 1.0% and 2.6%, per the Maryland Department of Labor.

Two Registrations, Two Agencies, One Checklist
The Comptroller of Maryland handles income tax withholding. The Maryland Department of Labor handles unemployment insurance. Completing the Combined Registration Application does not create your unemployment insurance account, and opening a BEACON account does not create your withholding account. Interest on unpaid unemployment balances runs at 1.5% per month, so a registration you forgot compounds quietly while you keep hiring. Put both on the same checklist and close them out on the same day.

Once the account exists you file quarterly and pay through the same portal. Your rate is recalculated annually based on your own claims experience, which is the practical argument for handling separations carefully from your very first hire onward. See the mechanics of state unemployment tax if this is new territory.

Step 4: Write a Job Posting That Meets the Wage Range Rule

Maryland requires the pay range in the posting itself, and the rule has no employer-size threshold. Since October 1, 2024, every public or internal posting for a position performed at least partly in Maryland must include the wage range with a minimum and a maximum, a general description of the benefits offered, and any other compensation elements. The range has to be what you believe in good faith at the time of posting.

If you never made a posting, the obligation does not disappear. You disclose the wage range and benefits description to the applicant before any discussion of compensation, and again whenever the applicant asks. Records go three years from the date the position was filled, or three years from the posting date if the role is never filled.

SituationWhat Maryland RequiresRecord to Keep
Public job postingWage range, general benefits description, other compensationCopy of the posting, 3 years after the role is filled
Internal postingSame three elements as a public postingCopy of the posting, 3 years
No posting madeDisclose range and benefits before discussing compensation and on requestNote of the disclosure in the applicant file
Remote role open to MarylandCovered if the work is performed at least partly in the stateSame as a public posting
Recruiter posts on your behalfYou remain responsible for the content of the postingCopy of what the recruiter published

Enforcement escalates rather than starting with a fine. A first violation draws a compliance order. A second can reach $300 per affected applicant or employee, and subsequent violations within three years can reach $600. Our pay transparency breakdown covers how this compares with other states.

Step 5: Complete Form I-9 by the Third Business Day

Every employee in the United States completes Form I-9, and the two sections carry different deadlines. The employee completes Section 1 on or before the first day of work. You complete Section 2 by the end of the third business day after the first day, examining original documents that establish identity and work authorization.

You cannot tell the employee which documents to present. They choose from the acceptable lists, you record what you actually see, and you sign. Retain the form for three years from the date of hire or one year after the employment ends, whichever is later. The rules on acceptable I-9 documentation are worth reviewing before your first Section 2.

Store I-9 Forms Separately From Personnel Files
I-9 forms can be inspected by federal officers, and the inspection reaches whatever folder the forms live in. If they sit inside the personnel file, an inspection exposes performance notes, medical information, and everything else in that folder. Keep a separate physical or digital location for I-9 forms from your very first hire, when it costs nothing to set up.

E-Verify is a separate system, and Maryland does not impose a general E-Verify mandate on private employers. Federal contractors whose contracts carry the E-Verify clause are the common exception. Participation in E-Verify never replaces the I-9. Every hire gets an I-9 regardless.

Step 6: Collect Form W-4 and the Maryland Withholding Certificate

Maryland takes two withholding forms, not one. Federal Form W-4 sets federal income tax withholding. The state Employee Withholding Exemption Certificate sets state and local withholding, and the Comptroller of Maryland now publishes it as Form MWH. Payroll systems and older guidance still call it the MW507, so expect both names on the same task.

Both forms need to be in hand before the first wage payment. Without them you withhold as if the employee claimed no exemptions, which produces the maximum withholding and an unhappy first paycheck conversation. The state certificate carries more weight in Maryland than a state withholding form does in most states, because the county income tax rides on the same withholding. County of residence is a required field on the form. The local rate follows where the employee lives rather than the work location, so an employee who lives in Baltimore City and works at your office elsewhere is taxed at the Baltimore City rate. Remote and hybrid staff make this a question you ask at hire and again after any move.

Form MWH, still widely called the MW507Maryland state and county income tax withholdingBefore the first wage paymentKept by the employer, copy to the Comptroller in certain cases

Direct deposit authorizationPayment methodBefore the first payroll runKept by the employer
Written notice at hirePay rate, regular paydays, leave benefitsAt the time of hiringGiven to the employee

Step 7: Give the Written Notice Maryland Requires at Hire

Maryland requires a written notice at the time of hiring covering three things: the rate of pay, the regular paydays the employer sets, and leave benefits. This is a statutory duty under the state wage payment law, not a best practice, and it is the step most first-time Maryland employers have never heard of.

The cleanest way to satisfy it is to fold all three into the offer letter and have the new hire sign. Rate of pay, the payday schedule, and a description of leave, in one dated document you can produce later. If you use an offer letter template, add the payday schedule and the leave summary rather than treating them as handbook material.

Two related duties start at the same moment. Every pay period you must provide a written pay statement that includes your registered business name, address and phone number, the payment date and pay period dates, hours worked for non-exempt employees, rates of pay, gross and net pay, every deduction by name and amount, and any additional bases of pay such as bonuses or commissions. And a change to a payday, or a cut in the wage rate, requires notice at least one pay period in advance. The same section says nothing stops you from raising a wage without advance notice.

What worked for me
I now treat the Maryland notice as part of the offer, not part of onboarding. The offer letter states the rate, names the paydays, and summarizes leave accrual, and it goes out for e-signature before the candidate accepts. That single change removed an entire category of scramble: nobody has to reconstruct what was promised, because the promise and the required notice are the same document, signed and timestamped.

Step 8: File the New Hire Report Within 20 Days

Report every new hire to the Maryland State Directory of New Hires within 20 days of the date of hire. The date of hire is the first day the employee performs services for pay, not the offer date and not the acceptance date. Reports are filed electronically through the state employer portal.

Federal law fixes the seven data elements: the employee name, address, Social Security number, and date of hire, plus your business name, address, and federal employer identification number. It also caps what any state may charge for a missed report at $25 per newly hired employee, rising to $500 where the employer and employee agree not to report. Rehires count too if the person was gone long enough to be separated. Our new hire reporting guide covers the state-by-state variation.

Chain the Report to the I-9
The new hire report needs the same facts you already collected for the I-9 and the W-4: name, address, Social Security number, and date of hire. Filing it in the same sitting takes a couple of minutes and removes a twenty-day countdown from your mental load. Every missed new hire report I have seen came from a founder who planned to do it later and then had a busy fortnight.

Step 9: Secure Workers Compensation Before the First Shift

Maryland law requires each employer to secure compensation for all covered employees. There is no headcount floor and no opt-out. This is the single biggest difference between hiring in Maryland and hiring in Texas, where private employers may decline coverage entirely, and it catches multi-state employers who assume the Texas model travels.

The statute gives you a short list of ways to comply: maintain insurance with an authorized insurer, participate in an approved self-insurance group, or qualify as an individual self-insurer. For a small business the first option is the only realistic one. Buy the policy from a licensed carrier, or through the state carrier of last resort if the standard market will not write you. Details on employer obligations sit with the Maryland Workers Compensation Commission.

Timing is the part people get wrong. Coverage has to exist when the first covered employee begins work, which is usually earlier than the first payroll run. Quote the policy while the offer is out so the certificate is in hand on Day 1. Confirm the classification codes describe the work the person will actually do, because a mismatch surfaces at audit with a premium adjustment attached. Read more on workers compensation insurance if this is your first policy.

Step 10: Post the Required Notices and Run the First 90 Days

Federal and Maryland notices have to be displayed where employees can see them before anyone starts work. On the federal side that means the Fair Labor Standards Act minimum wage notice, the OSHA job safety poster, the Employee Polygraph Protection Act notice, and the Family and Medical Leave Act notice for covered employers. Maryland adds its own set.

Health insurance coverage noticeMaryland Insurance AdministrationEmployers offering coverage

Employers in Montgomery County, Prince George’s County and Howard County post the county minimum wage notice in addition to the state version. All of these are free downloads from the issuing agencies. There is no reason to buy a poster package.

Compliance gets someone legally onto your payroll. It does not make them productive. The first 90 days are where the hiring investment either compounds or evaporates, and Gallup research has found that only 12% of employees strongly agree their organization does a great job of onboarding, which tells you how low the bar is and how cheap it is to clear it.

TimelineWhat HappensOwner

This is the workflow I built FirstHR around. The offer letter carrying the Maryland written notice goes out with e-signature. The I-9, W-4, and the state withholding certificate are collected before Day 1. Reminders cover the third business day and the twenty-day report, and the AI onboarding wizard turns the job description into a 30-60-90 day plan instead of a blank calendar. FirstHR is an onboarding and HR platform, not a payroll provider, so the payroll filings stay with your provider.

Maryland-Specific Rules That Change How You Hire

Maryland is not a light-touch state, but it is a predictable one. These are the rules that change the mechanics of a first hire rather than just the paperwork, and most of them apply from your very first employee with no size threshold at all.

Two registrations, two agencies
The Comptroller of Maryland issues your withholding account. The Maryland Department of Labor issues your unemployment insurance account. Doing one does not do the other.
Workers compensation is mandatory
State law requires every employer to secure compensation for all covered employees. There is no headcount floor and no opt-out, which is the opposite of the Texas model.
County income tax rides on withholding
Every Maryland county and Baltimore City levies a local income tax that you withhold based on where the employee lives, not where the job is.
Written notice at the time of hiring
You must give each employee written notice of the pay rate, the regular paydays you set, and leave benefits. Most founders learn this after the fact.
Pay range belongs in the posting
Every job posting needs a good-faith wage range, a general description of benefits, and any other compensation. There is no employer-size exemption.
Minimum wage is flat, counties are not
The state rate applies to every employer regardless of size and does not adjust automatically. Montgomery, Prince George’s and Howard counties set higher rates on their own schedules.
Sick and safe leave starts at hire
Leave accrues at one hour for every thirty hours worked. Larger employers must make it paid, smaller employers must at least make it unpaid.
Paid family leave is on the calendar
Payroll contributions for the state family and medical leave insurance program are scheduled to begin before benefits do, so budgeting starts early.

Minimum Wage, Overtime, and Tipped Pay

The state minimum wage is $15.00 per hour under the Fair Wage Act and applies to all employers regardless of size. It is not indexed, so there is no automatic annual bump and any increase requires legislation. Tipped employees who earn more than $30 a month in tips must reach the state rate overall, with at least $3.63 per hour paid in cash wages. Employees under 18 must earn at least 85 percent of the state rate. Overtime is time and a half over 40 hours in a week, with a 60-hour threshold for certain agricultural work, according to the Maryland Department of Labor Employment Standards Service.

Pay Frequency and Final Pay

You must set regular pay periods and pay each employee at least once every two weeks or twice each month. Administrative, executive, and professional employees may be paid less frequently. If a regular payday falls on a day the business does not operate, you pay on the preceding business day. On separation, all wages earned before the end of employment are due on or before the day the employee would have been paid had the job continued.

Accrued leave is a separate question. You are not required to pay out accrued leave at separation if you have a written policy limiting it, you gave the employee notice of your leave benefits at hire, and the policy says they are not entitled to payout. That written notice at hire is doing real work here, which is another reason not to skip Step 7. See final paycheck rules for the wider picture.

Earned Sick and Safe Leave

Maryland leave accrues at one hour for every thirty hours worked. Employers with 15 or more employees must provide it as paid leave. Employers below that threshold must provide it as unpaid leave. The law reaches any employer whose employees have a primary work location in Maryland, whatever the state of incorporation, and certain categories of employee are exempt. You can always be more generous than the statute.

Criminal History Timing

Maryland delays criminal history questions rather than banning them. An employer with 15 or more full-time employees may not require an applicant to disclose a criminal record or criminal accusations at any time before the first in-person interview, and the statute defines a criminal record broadly enough to include arrests and probation before judgment. That means nothing earlier in the funnel, including the application form itself, can ask. The rule took effect on February 29, 2020, and exceptions exist where another law requires or expressly authorizes the inquiry, and for employers providing programs, services, or direct care to minors or vulnerable adults. The same subtitle expressly preserves stricter local ordinances, so check the county before you finalize the workflow. Compare the national picture in our ban the box guide.

Paid Family Leave and Retirement

Maryland has a family and medical leave insurance program on the calendar. The state has set the initial contribution rate at 0.9% of wages up to the Social Security wage cap, split evenly between employer and employee at 0.45% each, with payroll deductions scheduled to begin January 1, 2027 and benefits available in January 2028 at up to 12 weeks of paid leave and up to $1,000 per week. Employers with fewer than 15 total employees, counting Maryland and out-of-state staff, are responsible for remitting 50% of the contribution rate. The detail sits in our Maryland paid family leave guide, alongside the separate state retirement savings mandate.

County Requirements: Montgomery, Howard, and Prince George’s

Maryland lets counties go above the state floor, and three of them do on wages. Track the rate by the work location of each employee, not by where your business is headquartered. A single company can owe three different minimums.

JurisdictionMinimum WageAs OfAdjustment Mechanism
Maryland statewide$15.00 for all employers regardless of sizeJanuary 1, 2024None. A change requires legislation.
Montgomery CountyTiered by employer size, from $15.95 up to $18.00July 1, 2026Increased each July 1 by CPI-W
Howard County$16.00 for all employers regardless of sizeJuly 1, 2026Set by county schedule
Prince George’s County$15.30January 1, 2026Set by county schedule
Baltimore CityState rate applies to private employersJanuary 1, 2024Follows the state rate

Montgomery County is the one to watch. Its rates are tiered by employer size and rise every July under a CPI-W adjustment, so a rate you verified for an earlier posting may already be stale. Wages are not the only local layer either. Maryland lets a local jurisdiction run criminal record screening rules stricter than the state standard, and several do, so a hiring workflow that clears the state rule can still miss a county one.

The practical approach: attach a work location to every role before you post it, and check the county rate at posting time rather than at offer time. If you have staff in more than one county, your handbook should describe the rule by location instead of stating one number. Our Maryland compliance hub collects the local variations in one place.

Employee vs Independent Contractor: Maryland Uses an ABC Test

For unemployment insurance purposes Maryland applies an ABC test, and all three prongs must be satisfied before work falls outside covered employment. This is stricter than the federal common-law control test, and it is the reason a classification that survives an IRS review can still fail in Maryland.

Under the state statute, work is not covered employment only if the individual is free from control and direction over its performance both in fact and under the contract, the individual customarily is engaged in an independent business or occupation of the same nature as the work, and the work is either outside the usual course of your business or performed outside any of your places of business.

ProngWhat It AsksWhere Small Businesses Fail
A: ControlIs the worker free from direction over how the work is done, in fact and under the contract?Setting hours, assigning a workflow, or requiring your tools
B: Independent businessDoes the worker customarily run an independent business of the same nature?The worker has one client, which is you
C: Outside the usual courseIs the work outside your usual course of business, or performed off your premises?A design studio hiring a designer as a contractor
All threeEvery prong must hold at oncePassing two prongs is a failed test, not a close call

A signed agreement does not settle the question. The state looks at the economics of the relationship, and reclassification brings back contributions plus interest and civil penalties. If the test is close, hire as an employee. The cost difference between a properly employed worker and a reclassified contractor is never in the contractor’s favor. Our employee versus contractor comparison covers the tests side by side.

The Mistakes That Cost Maryland Employers the Most

These are the errors I see most often at Maryland small businesses. Each one is a timing or sequencing failure rather than a knowledge failure, which is exactly why checklists and reminders beat compliance expertise at this size.

Registering with the Comptroller and assuming unemployment insurance is done
COSTYou keep hiring while the Department of Labor has no account for you. Contributions accrue anyway, and unpaid balances carry interest at 1.5% per month.
FIXTreat them as two separate tasks on the same checklist. Open the withholding account through the Comptroller, then register the unemployment insurance account through the employer portal at the Maryland Department of Labor.
Skipping the written notice at the time of hiring
COSTThe pay rate, the regular paydays, and the leave benefits all have to be in writing when the person is hired. A verbal offer plus a handshake does not satisfy the statute.
FIXBuild the notice into the offer letter and have it signed. Rate of pay, paydays, and leave in one document, stored with the employee record, dated on or before the first day.
Posting a job without the wage range
COSTA first violation draws a compliance order. The second can cost up to $300 per affected applicant or employee, and later violations up to $600.
FIXPut the good-faith minimum, the good-faith maximum, a general description of benefits, and any other compensation in every posting, including postings run by a recruiter on your behalf.
Waiting on workers compensation until the first payroll runs
COSTCoverage has to exist when the first covered employee starts, not when you get around to it. An uninsured injury turns into a direct claim against the business.
FIXBind the policy before the start date. Quote it while the offer is out so the certificate is in hand on Day 1, and confirm the classification codes match the actual work.
Missing the third business day on Form I-9
COSTFederal civil penalties apply per form, per employee, and they attach to the paperwork itself, so a late or incomplete form is a violation even when everyone is authorized to work.
FIXComplete Section 1 on Day 1 and Section 2 by the end of the third business day. Store I-9 forms separately from personnel files so an inspection never touches unrelated records.
Withholding county income tax based on your office address
COSTThe local tax follows the employee residence. Using your own county produces under-withholding or over-withholding for anyone who lives somewhere else, and you fix it at year end.
FIXCapture the county of residence on the Maryland withholding certificate at hire, and re-check it whenever an employee moves. Remote employees make this a routine question, not an edge case.

The pattern is consistent. The founder knows the I-9 is due. The founder knows the report has a deadline. What breaks is the week: a customer emergency lands on Day 2, and the third business day passes without anyone noticing. Every one of these mistakes is prevented by a task with a date on it, not by knowing the rule better.

What worked for me
The workers compensation timing is the one that still makes me uneasy. We had a start date confirmed and a policy quoted but not bound, and the new hire spent his first two days on site with no coverage in force. Nothing happened, which is the only reason it is a story and not a lawsuit. Now the certificate is a gate: no certificate, no start date, and the offer letter says so. It has never delayed a hire by more than a day.
Key Takeaways
Maryland splits employer registration across two agencies, the Comptroller of Maryland for income tax withholding and the Maryland Department of Labor for unemployment insurance, and you become an employer for unemployment insurance purposes as soon as you employ one person in the state.
Workers compensation is mandatory for all covered employees with no headcount floor and no opt-out, and coverage must be in force before the first shift, not before the first payroll run.
The written notice at the time of hiring covering pay rate, regular paydays, and leave benefits is a statutory duty, and it also preserves your ability to limit accrued leave payout at separation.
Every job posting for work performed at least partly in Maryland needs a good-faith wage range, a benefits description, and any other compensation, with no employer-size exemption.
The state minimum wage is $15.00 per hour and is not indexed, but Montgomery, Prince George’s and Howard counties set higher local rates that you track by work location.
Complete Form I-9 by the third business day, collect Form W-4 and Maryland Form MWH before the first paycheck, and file the new hire report within 20 days of the date of hire.

Frequently Asked Questions

What do I have to register for before hiring my first employee in Maryland?

Two state accounts, plus the federal EIN that comes before both. The Comptroller of Maryland issues your employer withholding account through the Combined Registration Application, which you file through Maryland Business Express or the Maryland Tax Connect portal. The Maryland Department of Labor issues a separate unemployment insurance account, which you open through the employer side of the BEACON portal. The Department treats you as an employer once you employ at least one person in the state, so the unemployment account is not optional for a single hire. Founders who register once and stop are usually the ones who registered with the Comptroller and never opened the labor account.

How long do I have to report a new hire in Maryland?

Twenty days from the date of hire. The report goes to the Maryland State Directory of New Hires, and the date of hire is the first day the employee performs services for pay. Federal law sets seven required data elements: employee name, address, Social Security number, and date of hire, plus your business name, address, and federal employer identification number. Federal rules cap what a state may charge for a missed report at $25 per newly hired employee, rising to $500 where the employer and the employee agree not to report. File it the same day you finish the I-9 and the step stops being something you can forget.

Is workers compensation insurance required in Maryland?

Yes, and there is no small-employer exemption to hide behind. Maryland law requires each employer to secure compensation for all covered employees, either by maintaining insurance with an authorized insurer, joining an approved self-insurance group, or qualifying as an individual self-insurer. Coverage is not elective the way it is in Texas, and it is not tied to a headcount floor. Buy the policy from a licensed carrier or through the state carrier of last resort, and make sure the coverage is bound before the first covered employee starts work rather than before the first payroll run. The Workers Compensation Commission runs an employer coverage verification tool, so a lapse is visible to anyone who looks, including an injured employee and their attorney.

What is the minimum wage in Maryland and does it rise automatically?

The state minimum wage is $15.00 per hour under the Fair Wage Act and applies to all employers regardless of size. It is not indexed. There is no automatic inflation adjustment at the state level, so any future increase takes new legislation. Tipped employees who earn more than $30 a month in tips must reach the state rate overall, and the employer must pay at least $3.63 per hour in cash wages. Employees under 18 must earn at least 85 percent of the state rate. Montgomery County, Prince George’s County and Howard County set higher local rates, and Montgomery County adjusts its rates each July by CPI-W.

Does Maryland require a state tax withholding form in addition to the W-4?

Yes. Every new hire completes federal Form W-4 for federal income tax and the state Employee Withholding Exemption Certificate for state and local withholding. The Comptroller of Maryland publishes that certificate as Form MWH, and most payroll systems and older guidance still list it under its longtime number, MW507. The state certificate matters more in Maryland than a state form does elsewhere because Maryland counties and Baltimore City each levy a local income tax that you withhold through the same system. The county of residence is a required field on the form, and the local rate follows where the employee lives, not where your office sits. Until the certificate arrives, you withhold as if the employee claimed no exemptions, which produces the maximum withholding.

Do I have to put a salary range in a Maryland job posting?

Yes, for any position performed at least partly in Maryland. Since October 1, 2024, a posting must include the wage range with a good-faith minimum and maximum, a general description of benefits, and any other compensation offered. There is no employer-size threshold, so a business making its very first hire is covered. If you never made a posting, you must disclose the range and benefits description to the applicant before any discussion of compensation and again on request. Keep the records for at least three years after the position is filled, or three years from the posting date if it never is.

Can I hire someone as an independent contractor in Maryland instead?

You can, but Maryland applies a strict ABC test for unemployment insurance purposes, and all three prongs must hold. The worker must be free from control and direction over performance in fact and under the contract, must customarily be engaged in an independent business of the same nature, and the work must be outside your usual course of business or performed outside any of your places of business. Prong B is what most small businesses fail, because the contractor is doing the same work the company sells. A signed contractor agreement does not settle the question. When the test is close, hire as an employee.
