Delaware Payroll: Employer Tax and Software Guide

Delaware looks like an easy payroll state until you actually run it. There is no sales tax, the income tax tops out at a modest 6.6 percent, and the whole state has fewer residents than Austin. Then you discover that Wilmington levies its own wage tax on anyone who so much as reports to an office inside city limits, that the state runs a three-tier deposit schedule most employers have never heard of, and that a paid leave program started pulling contributions from every paycheck in January 2025.

Add to that the fact that Delaware has no reciprocal tax agreement with any neighboring state, which matters enormously in a place where a meaningful share of the workforce crosses a line from Pennsylvania, Maryland, or New Jersey to get to work. A payroll setup that works cleanly in a big single-market state can quietly generate filing errors here.

This guide covers what Delaware requires of employers, why so many companies incorporated in Delaware have no Delaware payroll obligations at all, and how 10 payroll providers price the work at 10, 25, and 50 employees.

What Delaware actually requires from employers

Five separate obligations sit on top of federal payroll. Each has its own registration, its own filing rhythm, and its own way of going wrong.

State income tax withholding

Delaware uses seven graduated brackets. The first $2,000 of taxable income is untaxed, and the rate climbs to 6.6 percent on income above $60,000. Employers subtract a standard deduction of $3,250 for single filers or $6,500 for married filing jointly, compute tax on the remainder, then subtract a $110 credit per personal exemption before dividing across pay periods.

There is no Delaware W-4. According to the Delaware Division of Revenue, an employer may rely on the number of federal withholding allowances the employee claims. The state publishes Form SD/W-4A and Form W-4NR as worksheets, but the guide states plainly that neither is required of Delaware wage earners nor required to sit in employer files. Several payroll guides get this wrong and tell employers to collect a mandatory state form.

The three deposit schedules

Delaware assigns deposit frequency from a lookback period running July 1 through June 30 of the preceding year. This is where new employers most often stumble, because the schedule is assigned to you rather than chosen.

Eighth-monthly is the one that surprises people. It divides each month into eight periods ending on the 3rd, 7th, 11th, 15th, 19th, 22nd, 25th, and last day, with payment due within three business days of each close. A 50-person Delaware payroll can reach that threshold. Doing it by hand means roughly 96 deposit deadlines a year.

Unemployment insurance

State unemployment insurance comes entirely out of the employer's pocket. Employees contribute nothing. The taxable wage base is climbing on a schedule set by House Bill 433: it was $12,500 in 2025, sits at $14,500 for 2026, and moves to $16,500 in 2027 and after. New employers are assigned a standard rate until enough claims history exists to calculate an experience rate, typically after two to three years.

Wilmington city wage tax

Wilmington is the only Delaware municipality with a local income tax. Under 22 Del. C. section 902, the rate is capped at and set to 1.25 percent, and it reaches residents of the city on all earned income plus non-residents on income earned within city limits. The employer withholds it and registers separately with the City of Wilmington.

Delaware Paid Leave

The Healthy Delaware Families Act created a paid family and medical leave program funded by payroll contributions. The total is 0.8 percent of wages, capped at the Social Security taxable wage base, and it breaks into 0.32 percent for parental leave, 0.40 percent for medical leave, and 0.08 percent for family caregiving leave. Employers may deduct up to half from employees and remain liable for the entire amount if they fail to deduct it.

Contributions began January 1, 2025 and benefits became claimable January 1, 2026, with a maximum weekly benefit of $900. The headcount thresholds count Delaware employees specifically, which means a company that grows from 9 to 10 Delaware workers acquires a new payroll obligation mid-year.

The incorporation misunderstanding that sends founders here

A large share of people searching for Delaware payroll information do not have a Delaware payroll obligation and do not yet know it.

The Delaware Division of Corporations reports more than 2.1 million active business entities, 66.7 percent of the Fortune 500, and 81.4 percent of US-based IPOs in 2024 choosing Delaware as their corporate home. A company registered in Delaware but operating in Austin or Denver is an ordinary outcome, not an edge case.

Incorporation does not create payroll obligations. Payroll taxes follow the place where the employee physically performs the work. Under Delaware law, withholding is triggered when an employer maintains an office or transacts business within Delaware and pays wages for services performed there. A Delaware C-corp whose four engineers all work from Portland withholds Oregon tax, pays Oregon unemployment insurance, and files nothing with the Delaware Division of Revenue for payroll purposes.

The distinction matters for provider selection too. If you are incorporated in Delaware and employ people in four other states, the feature to shop for is multi-state filing at a sane price, not Delaware expertise.

10 payroll providers for Delaware employers compared

Every provider below files Delaware state withholding and unemployment insurance. The differences that matter are what happens with Wilmington local tax, what happens when someone works in a second state, 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, which is the single most useful characteristic for a Delaware employer whose workforce crosses state lines. Year-end W-2 and 1099 filing is included rather than billed separately. The first month is free with no credit card.

Gusto

The most common first payroll purchase for US small businesses, and deservedly so: tax filing is automatic, the interface is genuinely pleasant, and pricing is published. The Simple plan runs $49 per month plus $6 per employee after a base price increase in March 2026.

The Delaware-specific catch is that Simple covers single-state payroll only. Hire one person across the line in Pennsylvania and you are moved to Plus at $80 plus $12 per employee. Given how routine cross-border employment is in northern Delaware, model the Plus number rather than the Simple number if there is any chance of a second state.

Patriot Software

The cheapest legitimate full-service payroll on the market. Full Service is $37 per month plus $5 per employee and includes federal, state, and local tax filing plus new hire reporting. Basic is $17 plus $4 if you are willing to file the taxes yourself, which for a Delaware employer on an eighth-monthly schedule is a genuinely bad idea.

Additional state filings cost $12 per month each, so the price advantage narrows for employers with staff in Pennsylvania or Maryland. For a single-state Delaware shop under 20 people, nothing else comes close on cost.

SurePayroll

Owned by Paychex and aimed at very small employers and household employers. Full Service is $29 per month plus $7 per employee. The distinguishing feature for Delaware is a flat $9.99 monthly multi-state fee regardless of how many states are involved, rather than a per-state charge.

QuickBooks Workforce Payroll

Formerly QuickBooks Payroll, now renamed. Core is $50 per month plus $6.50 per employee. The reason to choose it is the same reason it has always been: if your books already live in QuickBooks Online, payroll entries land in the general ledger without any 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. That depth is the argument: Wilmington local tax, eighth-monthly deposits, and multi-state registrations are routine for ADP in a way they are not for a two-person bookkeeping setup.

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 and most buyers report paying more after add-ons. 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 are a recurring theme in customer reports. Worth a quote if you want a person to call about a Wilmington registration question rather than a help article.

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 different 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 that gives a small Delaware business access to benefits plans priced off a much larger risk pool, which is the actual reason most companies buy it.

Deel

Deel exists for companies employing people across borders. US Payroll is quote-based, Global Payroll is published at $29 per employee per month, and the employer of record product starts at $599 per employee per month. Its core HR tier is free. For a Delaware business hiring only in Delaware, this is the wrong category of product. For a Delaware-incorporated company with engineers in Poland and Brazil, it is often the only practical answer.

What each provider actually costs a Delaware employer

The table below models published rates at three headcounts, plus what happens when a second state enters the picture. That last column deserves attention in Delaware more than almost anywhere else in the country: the state is small enough that a commute across the Pennsylvania or Maryland line is unremarkable, and Delaware has no reciprocal agreement with any state.

Two patterns are worth naming. First, the budget providers are genuinely cheaper at small headcounts and stay cheaper: Patriot at 50 employees costs less than most competitors at 25. Second, the second-state column reorders the ranking. Gusto Simple is competitive until a single Pennsylvania hire forces the Plus tier, at which point the same 25-person payroll jumps from $199 to $380.

Choosing a payroll provider for Delaware

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

Beyond the payroll engine itself, the Delaware requirement most commonly missed is the 20-day new hire report to the Division of Child Support Services. Most full-service providers file it automatically, but the Basic tiers of self-service plans generally do not. Our guide to new hire reporting covers what the report must contain, and the Delaware HR compliance guide covers the surrounding employment law.

Before you choose

FirstHR does not process payroll, file payroll taxes, or administer benefits. Every provider above does something we do not, and if payroll is the problem you are solving, one of them is your answer.

What we do handle is the layer underneath: onboarding workflows, e-signatures on I-9s and offer letters, employee records, and document management for 5 to 50 employee US teams at a flat $98 to $198 per month. If your real bottleneck is that every new hire in Delaware means chasing paperwork, tracking the 20-day reporting deadline by hand, and hoping the right forms got signed, that is a different problem than payroll processing, and it is the one we built for.

Frequently Asked Questions

What payroll taxes do Delaware employers withhold?

State income tax on seven brackets from 0 to 6.6 percent, the 1.25 percent Wilmington wage tax where applicable, and the employee share of Delaware Paid Leave contributions. Employers separately pay unemployment insurance on the first $14,500 of wages in 2026, entirely out of their own funds. Federal withholding, Social Security, and Medicare apply on top.

Does Delaware have its own W-4 form?

No. The Division of Revenue permits employers to rely on federal withholding allowances. Forms SD/W-4A and W-4NR exist as optional worksheets for employees with complicated non-wage income or itemized deductions, and the state guide is explicit that neither is required of wage earners nor required in employer files.

How often does a Delaware employer deposit withheld tax?

Quarterly, monthly, or eighth-monthly, assigned from a lookback period covering July 1 through June 30 of the prior year. The thresholds are $6,020 and $33,460 of withholding. New employers with no prior record start on monthly until the next lookback recalculates them.

Who pays the Wilmington city wage tax?

Residents of Wilmington on all earned income, and non-residents on income earned within city limits, both at a flat 1.25 percent. The employer withholds and remits it and must register separately with the City of Wilmington. No other Delaware municipality levies a local income tax.

What are Delaware Paid Leave contributions?

A total of 0.8 percent of wages, capped at the Social Security wage base, split into 0.32 percent parental, 0.40 percent medical, and 0.08 percent family caregiving. Employers with fewer than 10 Delaware employees are exempt, those with 10 to 24 owe only the parental line, and those with 25 or more owe all three. Contributions started January 1, 2025 and benefits became claimable January 1, 2026.

Does incorporating in Delaware create Delaware payroll obligations?

No. Payroll taxes follow where employees physically perform work, not where the entity is registered. A Delaware-incorporated company whose staff all work in Texas withholds Texas-applicable taxes and files nothing with Delaware for payroll purposes. Franchise tax and the annual report are separate obligations that do follow the state of incorporation.

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

At 10 employees, published July 2026 rates run roughly $87 for Patriot Full Service, $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. ADP RUN and Paychex Flex quote individually. See the payroll pricing guide for how these models compare in general.
