Once your nonprofit has even one W-2 employee, you are responsible for collecting payroll taxes from each paycheck, depositing them with the federal government on a strict schedule, and reporting them on the right forms. This is not optional paperwork — the money you withhold from a worker's check (their income tax, Social Security, and Medicare) is trust fund money that belongs to the government the moment you withhold it. Hold it too long, or spend it on rent because cash is tight, and the IRS can come after your board members and staff personally.
The good news: a 501(c)(3) organization gets one meaningful break — it is exempt from federal unemployment tax (FUTA), so it never files Form 940 (IRS, Section 501(c)(3) FUTA exemption). Everything else — withholding, FICA, Form 941, electronic deposits, and year-end W-2s — works the same as it does for any small employer. This page walks through each piece, shows a worked paycheck and deposit example with real 2026 numbers, and spells out exactly what getting deposits late costs.
This is general educational information, not legal or tax advice. Payroll rules and dollar thresholds change yearly — confirm every figure against IRS Publication 15 (Circular E) and your state agency, or have a payroll provider do it for you.
What payroll taxes a nonprofit actually owes
The phrase "payroll taxes" bundles several separate obligations together. For a typical 501(c)(3) with W-2 staff, here is the full list and who pays each part. The IRS overview for charities lays this out at Exempt organizations: What are employment taxes?
| Tax | Who pays | Does your 501(c)(3) handle it? |
|---|---|---|
| Federal income tax withholding | Employee (you withhold it) | Yes — withhold from every check |
| Social Security (6.2% + 6.2%) | Split: employee + employer | Yes — withhold and match |
| Medicare (1.45% + 1.45%) | Split: employee + employer | Yes — withhold and match |
| Additional Medicare (0.9%) | Employee only, high earners | Withhold above $200,000 |
| FUTA (federal unemployment) | Employer only | No — 501(c)(3)s are exempt |
| State income tax withholding | Employee (you withhold it) | Usually — depends on state |
| State unemployment (SUTA) | Employer (varies) | Usually — special nonprofit rules |
The two halves of Social Security and Medicare together are called FICA. The employee pays 7.65% out of their wages, and your organization matches it with another 7.65% out of its own budget. That employer match is a real, often-overlooked cost: every $50,000 salary actually costs your nonprofit roughly $53,825 once you add the employer FICA share (as of 2026 — verify rates in Pub 15).
Before any of this applies, make sure the worker is genuinely an employee. If you are still deciding, start with employee vs. independent contractor — misclassifying staff to dodge payroll taxes is one of the costliest mistakes a small nonprofit can make.
The one real break: the 501(c)(3) FUTA exemption
Federal unemployment tax (FUTA) funds the federal half of the unemployment-insurance system. Ordinary employers pay it and file Form 940 every year. A 501(c)(3) organization does not. The IRS states plainly that an organization exempt under section 501(c)(3) "is also exempt from FUTA," and that this exemption cannot be waived (IRS, Section 501(c)(3) FUTA exemption). In practice that means: no FUTA tax, and no Form 940 to file.
Watch the (c) number
The FUTA exemption is tied specifically to 501(c)(3) status. If your group is exempt under a different subsection — 501(c)(4) social welfare, 501(c)(6) trade association, and so on — you are not FUTA-exempt and you do file Form 940. Confirm your exact classification on your IRS determination letter before assuming you can skip it (as of 2026 — verify).
Two cautions. First, the FUTA exemption is federal; it says nothing about state unemployment (SUTA). Most states do cover nonprofit employees, though many let 501(c)(3)s choose to be a "reimbursing employer" — paying the state back dollar-for-dollar only when a former employee actually collects benefits, instead of paying quarterly tax. That can save money for stable organizations and cost more for those with turnover. Check your state workforce agency. Second, the exemption does not touch FICA or withholding — those still apply in full.
What comes out of each check: withholding and FICA
Every payday, you calculate four things from each employee's gross pay before handing over the net check.
- Federal income tax withholding — based on the employee's Form W-4 and the tables/percentage method in IRS Publication 15 (Circular E). This is an estimate of the employee's eventual income tax, not a fixed rate.
- Social Security — 6.2% of wages, up to the annual wage base. For 2026 the Social Security wage base is $184,500 (up from $176,100 in 2025) — once an employee's year-to-date wages cross that, Social Security stops for the rest of the year (as of 2026 — verify on SSA.gov).
- Medicare — 1.45% of all wages, with no cap.
- Additional Medicare — 0.9% on wages above $200,000 in a year. You withhold this once an employee crosses $200,000 with you, regardless of their filing status; the employer does not match it (as of 2026 — verify).
Then your organization adds its employer match: another 6.2% Social Security and 1.45% Medicare on the same wages. Those employer amounts come out of your budget, not the employee's check, but they get deposited together. Source for all rates: Pub 15 and the SSA wage-base announcement.
Per-check withholding checklist
- Collect a signed Form W-4 from every employee before their first check.
- Withhold federal income tax using the current Pub 15 method.
- Withhold 6.2% Social Security until the employee hits the $184,500 wage base.
- Withhold 1.45% Medicare on all wages, no cap.
- Add 0.9% Additional Medicare once year-to-date wages pass $200,000.
- Add the employer 6.2% + 1.45% match from your own budget.
- Withhold state income tax if your state has one.
Depositing the money: EFTPS and Form 941
Withholding the money is only half the job. You must deposit it with the IRS, electronically, on a schedule the IRS assigns you. There are two pieces: the deposits (which happen between paydays) and Form 941 (a quarterly summary).
How you deposit — EFTPS only. Federal employment-tax deposits must go through the Electronic Federal Tax Payment System (EFTPS). You cannot mail a check. Enroll early, because activation takes several business days and you do not want to be locked out the week your first deposit is due.
How often — your deposit schedule. The IRS assigns you to either monthly or semiweekly deposits based on a lookback period. For calendar year 2026 the lookback period is July 1, 2024 through June 30, 2025 (Instructions for Form 941):
- Monthly depositor — if you reported $50,000 or less in employment taxes during the lookback period. Deposits are due by the 15th of the following month. Most small nonprofits land here.
- Semiweekly depositor — if you reported more than $50,000. Deposits for Wed/Thu/Fri paydays are due the following Wednesday; for Sat/Sun/Mon/Tue paydays, the following Friday.
The $100,000 next-day rule
If you ever accumulate $100,000 or more of undeposited employment taxes on any single day, you must deposit it by the next business day — and you immediately become a semiweekly depositor for the rest of this year and all of next (as of 2026 — verify in Pub 15). Rare for small orgs, but it applies the day it happens.
Form 941 — the quarterly reconciliation. Four times a year you file Form 941, Employer's Quarterly Federal Tax Return, reporting total wages, withholding, and FICA, and reconciling it against what you deposited. It is due the last day of the month after each quarter ends (April 30, July 31, October 31, January 31). Form 941 reports the tax; EFTPS pays it — they are two separate acts, and you must do both.
Worked example: one paycheck and one deposit
Meet "Riverside Literacy Project," a small 501(c)(3) with one full-time program director, Maria, paid $2,500 gross twice a month ($60,000/year). Riverside is a monthly depositor. Here is exactly what happens on one paycheck (2026 rates; Maria's federal income tax withholding of $230 is illustrative — your actual figure comes from her W-4 and Pub 15).
| Line item | Rate | Amount |
|---|---|---|
| Gross pay | — | $2,500.00 |
| Federal income tax withheld | per W-4 / Pub 15 | −$230.00 |
| Social Security (employee) | 6.2% | −$155.00 |
| Medicare (employee) | 1.45% | −$36.25 |
| State income tax (illustrative) | ~4% | −$100.00 |
| Maria's net check | $1,978.75 |
Now the part Maria never sees — what Riverside must deposit to the IRS for this one paycheck:
| Deposit component | Source | Amount |
|---|---|---|
| Federal income tax withheld | from Maria's check | $230.00 |
| Social Security — employee share | from Maria's check | $155.00 |
| Social Security — employer match | Riverside's budget | $155.00 |
| Medicare — employee share | from Maria's check | $36.25 |
| Medicare — employer match | Riverside's budget | $36.25 |
| Total federal deposit (this check) | $612.50 |
Over the month (two paychecks), Riverside accumulates $1,225.00 in federal employment taxes. As a monthly depositor, it pushes that amount through EFTPS by the 15th of the next month. At quarter's end it files Form 941 showing roughly $3,675 in total federal employment tax for the quarter, which should match the three monthly EFTPS deposits to the penny.
Notice three things. First, Riverside owes no FUTA — as a 501(c)(3) it skips Form 940 entirely. Second, the employer match ($382.50/month here) is a genuine budget cost no grant line should ignore. Third, of that $612.50 deposit, $421.25 is trust fund money (Maria's withheld income tax plus both employees' shares of FICA) — money that was never Riverside's to spend.
Year-end: W-2, W-3, and 1099-NEC
After December's last payroll, you summarize the year for each worker and the government.
- Form W-2 — one per employee, showing total wages and everything withheld. Give a copy to each employee and file copies with the Social Security Administration. The easiest filing route is the free SSA Business Services Online portal.
- Form W-3 — a single transmittal cover sheet that totals all your W-2s when you file with SSA. If you file W-2s electronically through SSA, the W-3 is generated for you.
- Form 1099-NEC — not for employees, but for any unincorporated contractor or vendor you paid $600 or more for services during the year. This is where correct worker classification pays off — employees get a W-2, contractors get a 1099-NEC, and the two are not interchangeable.
One hard deadline: January 31
W-2s (to employees and SSA) and 1099-NECs (to contractors and the IRS) are all due by January 31 following the tax year. Unlike some forms, there is no later electronic-filing date for these — January 31 is the deadline for both furnishing copies and filing with the agency (as of 2026 — verify). Fourth-quarter Form 941 is also due January 31.
For the upstream side of this — writing the offer, the W-4, and the role itself — see hiring and job descriptions and codify pay practices in your employee handbook.
What late deposits actually cost
The IRS treats employment-tax deposits more seriously than almost any other filing, because part of the money belongs to your employees and the government, not to you. Two penalties matter.
Failure-to-Deposit penalty. Deposit late, short, or by the wrong method and you owe a percentage of the deposit, scaled by how late it is (IRS, Failure to Deposit Penalty):
| How late | Penalty | On the $1,225 monthly deposit |
|---|---|---|
| 1–5 calendar days | 2% | $24.50 |
| 6–15 calendar days | 5% | $61.25 |
| More than 15 days | 10% | $122.50 |
| 10+ days after an IRS notice / immediate-payment demand | 15% | $183.75 |
These tiers do not stack — a deposit 20 days late is penalized at 10%, not 2% + 5% + 10% (as of 2026 — verify). Interest accrues on top.
The penalty that follows people home: the Trust Fund Recovery Penalty
If withheld income tax and the employee share of FICA — the trust fund portion — are not paid over, the IRS can assess a Trust Fund Recovery Penalty equal to 100% of that unpaid trust fund tax against any "responsible person" who willfully failed to pay it. That can reach an executive director, a treasurer or board officer with check-signing authority, or a bookkeeper. It is a personal liability, it cannot be discharged in bankruptcy, and it survives the nonprofit closing (IRS, TFRP). This is precisely why "we'll borrow from payroll taxes to make rent this month" is the single most dangerous sentence in nonprofit finance.
The takeaway: never let withheld payroll taxes sit in your operating account as if they were spendable cash. They are not.
How to run payroll without losing sleep
You can run all of this by hand using Pub 15 and EFTPS — and very small organizations sometimes do — but the math, the deposit clock, and the personal-liability stakes make payroll the classic case for automation. For almost any nonprofit with even one W-2 employee, a payroll service pays for itself the first time it makes a deposit you would otherwise have forgotten.
A workable setup for a small nonprofit
- Use a payroll platform (Gusto, QuickBooks Payroll, or ADP) that calculates checks, auto-deposits via EFTPS, and files Forms 941, W-2, and W-3 for you.
- Tell it you are a 501(c)(3) so it correctly suppresses FUTA / Form 940.
- Enroll in EFTPS yourself anyway, so you can verify deposits are actually landing.
- Keep withheld taxes mentally (or literally) separate from spendable cash.
- Reconcile each quarter's Form 941 against your EFTPS deposit history.
- If payroll and the books should really be one job, hire a bookkeeper to own both.
A modern payroll provider typically runs a low monthly base fee plus a small per-employee charge — trivial next to a single 10% failure-to-deposit penalty, let alone a Trust Fund Recovery Penalty. A bookkeeper is the next step up: worth it when payroll, deposits, and your general ledger should be handled by one person who reconciles them together. Fit payroll into your broader money systems with financial management basics, and see benefits basics and FLSA exempt status and overtime for the rules that decide how much gross pay goes through payroll in the first place.
Payroll is recurring. Your funding should be too.
Salaries, FICA, and deposits hit every two weeks — but most nonprofit revenue arrives in unpredictable lumps. Good Circles helps close that gap. A supporter picks your cause once, then a share of their everyday local spending funds you automatically — an estimated $72 per active supporter per year, or roughly $36,000 a year from 500 supporters. It is recurring, unrestricted, and free for nonprofits, so it can quietly help cover the payroll your mission depends on.

FAQ
Does a 501(c)(3) nonprofit have to pay payroll taxes?
Yes — with one exception. A 501(c)(3) must withhold federal income tax and the employee share of Social Security and Medicare (FICA) from each W-2 employee's check, and it must pay the employer match of Social Security and Medicare. The one break is federal unemployment tax (FUTA): a 501(c)(3) is exempt and does not file Form 940. Note that this exemption applies only to 501(c)(3) organizations — groups exempt under other subsections, like 501(c)(4) or 501(c)(6), still owe FUTA. State unemployment (SUTA) usually still applies regardless.
How often does my nonprofit deposit payroll taxes, and how?
All federal employment-tax deposits go through EFTPS at eftps.gov — you cannot mail a check. How often depends on your lookback period. If you reported $50,000 or less in employment taxes during the lookback period (for 2026, July 1, 2024 through June 30, 2025), you are a monthly depositor and deposit by the 15th of the following month. Above $50,000 you deposit semiweekly. Separately, you file Form 941 every quarter to reconcile what you withheld against what you deposited. Enroll in EFTPS early, because activation takes several business days.
What happens if we deposit payroll taxes late?
The IRS charges a Failure-to-Deposit penalty that scales with lateness: 2% for 1–5 days late, 5% for 6–15 days, 10% for more than 15 days, and 15% if you ignore an IRS notice for 10+ days. The tiers do not stack, and interest is added. Far more serious is the Trust Fund Recovery Penalty: if the withheld income tax and employee FICA — the trust fund portion — are not paid over, the IRS can assess 100% of that amount personally against a responsible person, such as your executive director, treasurer, or bookkeeper. It is a personal liability that bankruptcy does not erase. Never spend withheld payroll taxes on operating costs.
What year-end forms does a nonprofit employer file?
Three main ones. Form W-2 goes to each employee and to the Social Security Administration, summarizing the year's wages and withholding; you can file it free through SSA Business Services Online. Form W-3 is the transmittal cover sheet that totals your W-2s for SSA. Form 1099-NEC goes to any unincorporated contractor you paid $600 or more for services — contractors, not employees. W-2s and 1099-NECs are all due by January 31 following the tax year, the same date as the fourth-quarter Form 941. As a 501(c)(3), you do not file Form 940 for FUTA.
