Maine Payroll: Employer Tax and Software Guide

Maine looks like an easy payroll state right up until you count the systems. There is no local income tax, no city payroll levy, no county surcharge, and the whole state has fewer people than metropolitan Denver. Then you register a business and discover you are filing into three separate portals run by two different agencies, on three different rhythms, before you have paid anybody.

The unemployment wage base is $12,000, one of the lowest in the country, which reads like good news until you notice two assessments stacked on top of the rate. Withholding is graduated across three brackets and runs on a state-specific certificate that most employers have never heard of. And a paid family and medical leave program that had been quietly collecting contributions since the start of 2025 began paying benefits in May.

This guide covers what Maine requires from employers, the obligations that state tax registration does not cover, and how 10 payroll providers price the work at 10, 25, and 50 employees.

What Maine requires from employers

Four state obligations sit on top of federal payroll: income tax withholding, unemployment contributions, paid family and medical leave, and workers compensation coverage. Each has its own registration, its own portal, and its own filing calendar.

State income tax withholding

Maine taxes wage income on a graduated schedule with three rates, and no municipality in the state adds an income tax on top. Withholding is calculated with either the wage bracket tables or the percentage method published by Maine Revenue Services, applied to annualized income after allowances and a state standard deduction.

The inputs matter as much as the brackets. Each withholding allowance is worth $5,300, and the Maine standard deduction used in the withholding calculation is $12,450 for a single employee and $27,750 for a married employee, phasing out above $102,250 and $204,550 of annualized income respectively. Those deduction figures differ slightly from the ones on a Maine return, which is deliberate.

The certificate is where Maine catches people out. Form W-4ME, the Maine Employee's Withholding Allowance Certificate, is a real separate document, and Maine Revenue Services expects it on the same date the federal Form W-4 arrives. Without a valid W-4ME, the employer must withhold as if the employee were single with no allowances.

How the calculation actually runs

Maine withholding is not a flat percentage applied to gross pay, and understanding the sequence explains most of the errors that show up in a first run. The percentage method works in six steps, and every one of them operates on an annualized figure rather than the pay period figure in front of you.

Start by multiplying the period wages by the payroll frequency: 52 for weekly, 26 for biweekly, 24 for semimonthly, 12 for monthly. Multiply the allowances claimed on the W-4ME by $5,300. Work out the standard deduction, which is $12,450 for a single employee and $27,750 for a married employee until the phaseout ranges begin. Subtract the allowance total and the deduction from the annualized wage to get annualized income, run that through the rate schedule above, then divide back down by the same payroll frequency and round to the nearest dollar.

A single employee paid $1,000 a week claiming two allowances gives $52,000 annualized, less $10,600 in allowances and $12,450 of standard deduction, for $28,950 of annualized income. That crosses the first bracket, so the annual withholding is $1,589 plus 6.75 percent of $1,550, or $1,694, which divides to $33 a week. Run the same employee at $300 a week and the annualized income comes out negative, so the withholding is zero. That second case is the one people query, and it is correct.

Deposit schedules and returns

Filing frequency and payment frequency are two different questions in Maine, and mixing them up is the most common administrative error. Every registered employer files Form 941ME quarterly, due the last day of the month after quarter end, whether or not anything was withheld. Only the payment schedule varies, and it is set by a lookback test rather than by current volume.

Employers whose withholding during the state lookback period reached $18,000 or more remit on a semiweekly schedule using Form 900ME. That works on the federal pattern: wages paid Wednesday, Thursday, or Friday are due the following Wednesday, and wages paid Saturday through Tuesday are due the following Friday. Everyone else pays with the quarterly return. Maine reviews each account at the end of the year and notifies employers whose frequency changes, so a growing business can move into semiweekly remittance without doing anything differently.

Three electronic mandates sit on top. Electronic filing of the quarterly return is required for every registered withholding account, with waivers available only for demonstrated hardship. Any taxpayer with $10,000 or more in combined annual Maine tax liability across all state taxes must pay electronically. And W-2 and 1099 information return data must reach Maine Revenue Services electronically by January 31, because paper copies are not accepted at all. For late filers, interest for the current calendar year runs at 9 percent compounded monthly, with a late payment penalty of 1 percent per month up to 25 percent.

Unemployment contributions

Unemployment insurance is entirely employer-funded in Maine, and it applies to only the first $12,000 of gross earnings per employee per calendar year. The Maine Department of Labor rate array for the current rate year spreads employers across 20 experience rating categories, and the lowest of those categories carries an adjusted unemployment rate of 0.00 percent.

The low wage base is the whole story here. A new employer at the combined 2.54 percent rate pays roughly $305 per employee per year no matter what anyone earns, and even the worst experience category tops out near $792. Compare that with a state running a $50,000 base and the arithmetic is not close.

One mechanic is worth understanding before you read a rate notice. The scholarship fund assessment is offset: each employer's unemployment rate is reduced by an amount equal to the scholarship fund rate, so the two lines are not simply additive in cash terms. Contributions and wage detail are reported quarterly on Form ME UC-1 through the ReEmployME system, due the last day of the month after quarter end.

Paid family and medical leave

This is the newest and largest change to Maine payroll taxes in years. Contributions started with pay dates on or after January 1, 2025, and benefits became payable for leave taken on or after May 1, 2026, with applications opening at the end of March.

The rate structure is set through 2027, according to the Maine Department of Labor paid leave program, and the program provides up to 12 weeks of leave. Contribution wages follow the unemployment definition of total subject wages, but the calculation excludes amounts above the annual Social Security wage base, so the two lines diverge sharply for higher earners.

Two reporting details trip up payroll setups. Employee contributions are withheld after federal and state income taxes rather than before, and they must appear in Box 14 of the Form W-2 under the label MEPFML. Where an employer chooses to cover the employee half, that amount becomes additional compensation and belongs in the employee's federal gross wages.

Minimum wage and the salary threshold

The Maine minimum wage is $15.10 per hour effective January 1, 2026, up from $14.65. The Maine Department of Labor adjusts it every January using the cost-of-living index for the Northeast Region under a rule Maine voters put in place by referendum in 2016; the latest step reflected a 3.1 percent increase in that index.

Two points deserve attention. The state rate applies to agricultural and non-agricultural work alike, and the salary floor for overtime exemption is a state figure that sits well above the federal one, so a Maine employer applying only the federal threshold will misclassify people. The tipped wage rule requires the employer to make up any weekly shortfall between direct wages plus tips and the full minimum.

Pay frequency and final pay

Maine requires wages to be paid at regular intervals not exceeding 16 days, under 26 M.R.S. section 621-A. That single number quietly rules out a semimonthly schedule for most employers, because a semimonthly cycle produces intervals longer than 16 days in most months. Lengthening the interval requires written notice to the employee at least 30 days in advance. Read the exception in the same sentence before you redesign the calendar: members of the family of the employer and salaried employees are carved out, so the 16-day limit bites hardest on hourly staff.

The final paycheck rule in 26 M.R.S. section 626 is unusually simple: an employee leaving employment must be paid in full no later than the next established payday, and Maine makes no distinction between a resignation and a discharge. What it adds instead is a vacation payout obligation. Unused paid vacation accrued under the employer's policy on and after January 1, 2023 must be paid out at separation, with exceptions for employers of 10 or fewer employees and for public employers.

The penalty for getting that wrong is where Maine stops being gentle. An employer that fails to pay owes the unpaid wages and accrued vacation, a reasonable rate of interest, an additional amount equal to twice those sums as liquidated damages, and the employee's costs of suit including reasonable attorney fees. A forgotten vacation balance on a departing employee therefore becomes a multiple of the original number rather than a correction. If your payroll platform does not carry vacation balances into the termination workflow, somebody has to check manually before the final run goes out.

Registration and new hire reporting

There is no single front door. Income tax withholding is registered through the Maine Tax Portal, unemployment contributions through ReEmployME, and paid family and medical leave through the separate state paid leave portal. Workers compensation coverage sits alongside all three.

New hires are reported to the Department of Health and Human Services within seven days of the date the employee first performs services for pay, under 19-A M.R.S. section 2154, which is well inside the 20 days federal law lets a state allow. A returning employee counts as a new hire only after a separation of at least 60 consecutive days. The same section also catches contractors: a services contract expected to reach $2,500 in a year has to be reported on the same seven-day clock.

The local layer that state registration does not cover

Maine has no local income tax and no municipal payroll levy, which leads employers to assume state registration finishes the job. Four obligations say otherwise, and none of them is triggered by opening a withholding account.

Your payroll provider has to be licensed here

This one is close to unique. Payroll processing companies operating in Maine must register annually with, and be licensed by, the state Bureau of Consumer Credit Protection, and Maine Revenue Services tells employers directly to verify that their processor is licensed and has provided proof of fidelity insurance. The reasoning is blunt: the employer, not the processor, bears the responsibility for meeting its payroll tax obligations, so a processor failure lands on the employer.

Earned paid leave above 10 employees

Maine was the first state to require general-purpose paid leave usable for any reason, not only for illness. Under 26 M.R.S. section 637 the obligation applies to any employer with more than 10 employees in the usual and regular course of business for more than 120 days in a calendar year, which means a summer-heavy business can cross into coverage without ever having 11 people on the payroll year round.

Covered employees accrue one hour of leave for every 40 hours worked, up to 40 hours in a year of employment. Accrual begins at the start of employment, but the employer may require 120 days of employment before the leave is usable, unused hours carry into the following year, and seasonal industry employment is excluded. It is a separate system from paid sick leave in other states and separate again from the paid family and medical leave contribution.

Municipal minimum wage ordinances

Maine permits municipalities to set their own minimum wage, and the state minimum wage poster tells employers with staff working in Portland or Bangor to check with municipal officials because additional local regulations may apply. The applicable rate follows the worksite, not the company address, so a payroll system that assigns a single wage floor from the business location can underpay a crew working in a city with its own ordinance. Confirm the current municipal figure with the city directly rather than relying on a vendor summary.

The state retirement savings mandate

Maine operates a state-facilitated automatic IRA program for employers that do not sponsor a qualified retirement plan. Employers with five or more covered employees that have been in business at least two calendar years fall inside it, and registration is a separate action from any payroll tax account. Enrolled employees are defaulted into a payroll deduction at a rate set by the program, with automatic annual escalation to a ceiling, and they may change the rate or opt out entirely.

The registration deadlines for both size bands have already passed, which means a business crossing the five-employee line today is late by default rather than early. Penalties accrue per covered employee, so the exposure scales with headcount rather than sitting as a flat fine. Employers that already offer a qualified plan are exempt, but the exemption has to be claimed rather than assumed; silence looks the same as non-compliance from the outside.

The count of things nobody registers for you

Put the whole picture together and a new Maine employer is transacting in more places than the tax accounts suggest. Withholding lives in the Maine Tax Portal and unemployment contributions live in ReEmployME, both triggered by the first employee. Paid family and medical leave sits in a third state portal on its own schedule. New hire reports go to the Department of Health and Human Services on every hire, within seven days.

Earned paid leave produces no filing at all, only records, and it switches on at more than 10 employees for more than 120 days in a calendar year. The retirement savings mandate switches on at five employees where no plan is offered. Municipal wage ordinances follow worksites. None of those last three is triggered by opening a tax account, which is precisely why they get missed: nothing arrives in the post to remind you.

10 payroll providers for Maine employers compared

Every provider below files Maine withholding and unemployment contributions. The differences that matter here are whether the platform remits paid family and medical leave through the state portal rather than only computing it, whether the vendor is licensed as a Maine payroll processor, and whether the price is published at all.

OnPay

One plan at $49 per month plus $6 per employee, with every feature included and no tiers to climb. Tax filing covers all 50 states with no multi-state surcharge, and year-end W-2 and 1099 filing sits in the base price rather than being billed separately. OnPay also maintains state-level tax documentation, which is a reasonable proxy for whether a vendor keeps up with a program like Maine paid leave in its first year of benefit payments.

Gusto

The most common first payroll purchase for US small businesses. Tax filing is automatic, the interface is pleasant, and pricing is published. Simple runs $49 per month plus $6 per employee following a base increase in March 2026.

The catch for Maine employers is that Simple covers single-state payroll only. Maine borders New Hampshire, which has no wage income tax and a very different filing profile, and cross-border hiring is routine along that line. A single hire across it moves you to Plus at $80 plus $12 per employee, so model the Plus number if a second state is even plausible.

Patriot Software

The cheapest legitimate full-service payroll available. Full Service is $37 per month plus $5 per employee and includes federal, state, and local tax filing plus new hire reporting, which matters in a state with a seven-day new hire window. Basic is $17 plus $4 if you file taxes yourself.

Filing Maine yourself is more work than the price gap suggests. A Basic subscriber handles Form 941ME quarterly, Form ME UC-1 quarterly in a different system, and paid leave remittance in a third, then reconciles all of it at year end. Additional state filings cost $12 per month each.

SurePayroll

Owned by Paychex and aimed at very small employers and household employers. Full Service is $29 per month plus $7 per employee, with a flat $9.99 monthly multi-state fee regardless of how many states are involved. For a Maine business with a couple of people over the New Hampshire line, that flat structure beats per-state pricing outright.

QuickBooks Workforce Payroll

Formerly QuickBooks Payroll, now renamed. Core is $50 per month plus $6.50 per employee. The reason to pick it has always been the same: if your books already live in QuickBooks Online, payroll entries reach the general ledger without an export step. Per-employee pricing rose across all tiers on July 1, 2026.

ADP RUN

ADP processes payroll for roughly one in six American workers and has the deepest tax compliance engine in the category. For a Maine employer the practical argument is timing: a paid family and medical leave program in its first year of benefit payments generates rule clarifications, and those reach ADP's tables without anyone at your company reading program bulletins.

The cost is opacity. ADP does not publish RUN pricing; third-party estimates put Essential near $79 per month plus $4 per employee, but every quote is individual. Contracts typically run a year with automatic renewal and a 30 to 60 day cancellation window.

Paychex Flex

Paychex competes with ADP on the same terms: a service relationship rather than a software subscription, with a named contact at higher tiers. Pricing is quote-only, and quarterly administrative charges appear regularly in customer reports. Worth a quote if you would rather call a person about a paid leave reconciliation than read program rules.

Paylocity

Paylocity sits between small-business payroll and full HCM, aimed at companies that have outgrown basic payroll but do not want enterprise complexity. It publishes detailed per-state tax facts, and native leave accrual tracking suits the Maine earned paid leave obligation, which requires per-employee hour accounting rather than a lump grant. Pricing is quote-based and implementation is a project rather than a signup.

Rippling

Rippling sells a unified employee record where payroll, HR, and IT provisioning share one data model. The core platform is $35 per month plus $8 per employee, with payroll as a separate module. Real-world all-in costs land between $25 and $45 per employee per month once you assemble a working configuration.

Justworks

Two products under one name. Payroll is $50 per month plus $8 per employee and is straightforward software. PEO Basic at $79 per employee per month is a co-employment arrangement giving a small Maine business access to benefits priced off a much larger risk pool, which is the actual reason most companies buy it.

What each provider actually costs a Maine employer

The table below models published rates at three headcounts, plus what happens when a second state enters the picture. That last column deserves more weight in Maine than in most states, because the New Hampshire border runs through the state's biggest labour market and a single hire across it changes which provider wins.

Two patterns stand out. Patriot holds the lowest published price at 10 and 25 employees, and at 50 the only figure underneath it belongs to ADP RUN, which publishes no rates at all, so that number is a third-party estimate rather than a quote anyone has to honour. The second-state column then reorders things: Gusto Simple is competitive until one out-of-state hire forces the Plus tier, at which point a 25-person payroll goes from $199 to $380 per month.

Software price is also not the whole Maine number. A 25-person employer at the new employer rate pays roughly $7,600 a year in unemployment contributions alone, before the paid family and medical leave contribution and before touching the subscription line. Those are statutory costs no provider changes, but they belong in the budget next to the software.

The mix inside that figure is what makes Maine unusual. Unemployment contributions are capped by the $12,000 wage base, so they flatten out as salaries rise and stay near $305 per person at the new employer rate no matter what anyone earns. The paid leave contribution runs on wages all the way to the Social Security cap, so it scales with payroll rather than headcount. A team of 25 people at $45,000 and a team of 25 people at $90,000 pay nearly the same unemployment bill and roughly double the paid leave bill.

That has a practical consequence when you compare quotes. A per-employee software fee tracks headcount, the same way unemployment does, while the largest statutory line on a well-paid Maine team tracks wages. For a professional services firm with a small number of high earners, the subscription is a rounding error against the paid leave contribution. For a seasonal employer with a large low-wage crew, the per-employee software fee is the line that actually moves, and the flat-fee providers win by a wider margin than the headline rates suggest.

Choosing a payroll provider for Maine

Four questions separate providers that will work here from providers that will quietly generate correction notices.

One item sits outside the payroll engine entirely. Every Maine new hire needs a federal I-9 and W-4, a Form W-4ME collected on the same day, a direct deposit authorization, and a new hire report filed within seven days.

Before you choose

FirstHR does not process payroll, file payroll taxes, move money, or administer benefits. Every provider above does something we do not, and if running payroll is the problem in front of you, one of them is the answer.

What we handle is the layer that feeds payroll: onboarding workflows, e-signatures on I-9s and offer letters, employee records, and HR document management for US teams without a dedicated HR person, at a flat $98 to $198 per month. If the recurring problem is that the W-4ME never got collected alongside the federal W-4, the direct deposit form is unsigned, and nobody is sure whether the seven-day new hire report went out, that is a document collection failure rather than a payroll processing failure, and it is the kind of gap we built for.

The New England neighbours are also worth reading if you hire across a line. Massachusetts and Connecticut both run paid family leave programs of their own, with different contribution splits and different wage caps from the Maine version.

Rhode Island is a third variation on the same idea, funded from the employee side. New Hampshire, the one border Maine employers cross most often, sits at the opposite end of the range: no tax on wage income, no state paid leave contribution, and a completely different set of registrations to open before the first run.

Frequently Asked Questions

What are the Maine payroll taxes an employer has to handle?

Four state obligations on top of federal: income tax withholding to Maine Revenue Services, unemployment contributions to the Department of Labor with two assessments attached, paid family and medical leave contributions through a third portal, and workers compensation coverage. Each has its own registration and filing rhythm.

What is the Maine income tax rate for payroll withholding?

Three graduated rates: 5.80, 6.75, and 7.15 percent, with no local income tax anywhere in the state. For a single employee the brackets break at $27,400 and $64,850 of annualized income; for a married employee at $54,850 and $129,750. Allowances are worth $5,300 each.

Is Form W-4ME required for new employees in Maine?

Yes. Maine Revenue Services expects the W-4ME on the same date the federal W-4 is provided, and without a valid one the employer must withhold as if the employee were single with no allowances. Claiming more Maine allowances than the form permits requires a separate variance certificate from the state.

What is the Maine unemployment insurance wage base and rate range?

The base is $12,000 of gross earnings per employee per calendar year, one of the lowest in the country, and contributions are employer-paid. Adjusted rates run from 0.00 to 6.29 percent across the 20 experience categories in the rate year array, and the two assessments bring the combined range to 0.31 through 6.60 percent.

What is the Maine new employer unemployment rate?

2.23 percent, plus 0.14 percent for the Competitive Skills Scholarship Fund and 0.17 percent for the Unemployment Program Administrative Fund, for a combined 2.54 percent. Against a $12,000 wage base that caps annual exposure at roughly $305 per employee.

How much are Maine paid family and medical leave contributions?

1 percent of wages for employers with 15 or more employees, half of which may be deducted from the employee, and 0.5 percent for employers below 15, which may be deducted in full. No more than 0.5 percent may ever come from an employee. Contributions stop above the annual Social Security wage base.

When did Maine paid family and medical leave benefits start?

Benefits became payable for leave taken on or after May 1, 2026, with applications opening on March 30. The program provides up to 12 weeks. Contributions had been running since January 1, 2025 to build the fund ahead of the first claims.

What is the Maine minimum wage?

$15.10 per hour effective January 1, 2026, up from $14.65, and indexed each January to the cost-of-living index for the Northeast Region. The service employee direct wage is $7.55 for anyone regularly receiving more than $191 a month in tips, and the state overtime exempt salary minimum is $871.16 per week.

How often must Maine employees be paid?

At regular intervals not exceeding 16 days under 26 M.R.S. section 621-A, which rules out a semimonthly schedule for most employers. Lengthening the interval requires 30 days of written notice. Members of the family of the employer and salaried employees sit outside the rule entirely, and narrower exceptions cover public agency compensatory time, school personnel, and volunteer firefighters.

When is a final paycheck due in Maine?

No later than the employee's next established payday, with no difference between a resignation and a discharge. Unused vacation accrued on and after January 1, 2023 must also be paid out, except by employers with 10 or fewer employees. Failure to pay carries liquidated damages of twice the amount owed plus interest and attorney fees.

How often does a Maine employer file withholding returns?

Quarterly on Form 941ME, due the last day of the month after quarter end, filed electronically and required even when nothing was withheld. Payment is a separate question: employers reaching $18,000 in the state lookback period remit semiweekly on Form 900ME, everyone else pays with the quarterly return.

Does Maine require paid leave for small employers?

Earned paid leave applies above 10 employees for more than 120 days in a calendar year, accruing at one hour per 40 hours worked up to 40 hours annually and usable for any reason. Paid family and medical leave contributions apply at every size; only the rate changes at 15 employees.

How do I register a business for Maine payroll taxes?

Withholding through the Maine Tax Portal, unemployment through ReEmployME, and paid leave through the state paid leave portal, plus workers compensation coverage. New hires go to the Department of Health and Human Services within seven days, and any payroll processor you hire must be licensed by the Bureau of Consumer Credit Protection.

How much does payroll software cost for a Maine small business?

At 10 employees, published July 2026 rates run roughly $87 for Patriot Full Service, $99 for SurePayroll, $109 for OnPay or Gusto Simple, $115 for QuickBooks Core, and $130 for Justworks Payroll. At 50 employees the same plans land between $287 and $450.
