Payroll tax deadlines depend on how often you pay your employees and which taxes you owe

Federal payroll taxes — Social Security, Medicare, and federal income tax withholding — are due on a schedule set by the IRS, not on a date that applies to every business. The schedule depends on how much you owe in total payroll taxes each quarter. State income tax withholding, unemployment insurance, and disability insurance each have their own deadlines, which vary by state.

The IRS publishes a deposit schedule that tells you whether taxes are due weekly, twice monthly, or monthly. You find your schedule based on your total payroll tax liability in a lookback period — usually the prior four quarters. Missing a deadline triggers penalties and interest, even if you pay the full amount later.

Key Takeaways

  • Most employers deposit federal payroll taxes either weekly or twice monthly, depending on how much they owe in a lookback period set by the IRS.
  • Federal Form 941 (quarterly return) and Form 940 (annual unemployment tax return) have fixed deadlines: the last day of the month following the quarter or year.
  • State payroll tax deadlines vary by state and by tax type — some states require weekly deposits, others monthly, and a few have different schedules for income tax versus unemployment insurance.
  • Deposits must go to an authorized bank or the Electronic Federal Tax Payment System (EFTPS), not directly to the IRS.
  • The IRS applies a safe harbor rule: if you deposit late but within three business days, penalties may be waived if you have a reasonable cause.

Federal deposit schedules: weekly versus twice monthly

The IRS assigns you to one of two deposit schedules based on your lookback period — the total federal payroll taxes you owed in the four quarters ending June 30 of the prior year. If you owed $50,000 or less during that period, you are on a monthly deposit schedule. If you owed more than $50,000, you are on a semi-weekly deposit schedule (twice per week).

On a monthly schedule, you deposit all payroll taxes for a calendar month by the 15th of the following month. On a semi-weekly schedule, deposits are due on Wednesday for payroll processed Wednesday through Friday, and on Friday for payroll processed Saturday through Tuesday. The IRS sends you a notice (Form SS-8 or a letter) telling you which schedule applies to your business.

New employers are placed on a monthly schedule by default. If your lookback period total crosses the $50,000 threshold, the IRS notifies you and moves you to semi-weekly starting the next quarter.

Quarterly and annual return deadlines

Even if you deposit taxes on a weekly or monthly basis, you must file a quarterly return to reconcile what you deposited against what you actually owed. Form 941 (Employer's Quarterly Federal Tax Return) is due on the last day of the month following the end of each quarter: April 30 for Q1, July 31 for Q2, October 31 for Q3, and January 31 for Q4.

Form 940 (Employer's Annual Federal Unemployment Tax Return) covers federal unemployment insurance (FUTA) and is due January 31 of the year following the tax year. If you pay all FUTA tax by January 31, you can file Form 940 by February 10 instead.

If you cannot file by the deadline, you can request an extension using Form 7004, which gives you five additional months. The extension delays filing, not payment — taxes are still due on the original deadline.

State payroll tax deadlines

State income tax withholding, state unemployment insurance (SUI), and state disability insurance (SDI, where applicable) each have their own deposit and filing schedules. Most states require deposits monthly or quarterly, but some require weekly deposits if you have a large payroll.

State filing deadlines typically fall 15 to 30 days after the end of each quarter or month. For example, California requires SUI and SDI deposits by the 15th of the following month, while New York requires them by the 15th as well. Some states allow you to file and deposit on the same day; others require deposits before the filing deadline.

You can find your state's specific deadlines through your state's department of revenue or labor website. Many states post a payroll tax calendar showing deposit and filing dates for the full year.

How to make deposits: EFTPS and authorized banks

Federal payroll tax deposits must be made through the Electronic Federal Tax Payment System (EFTPS) or through an authorized financial institution. EFTPS is free and allows you to schedule deposits online or by phone. You must enroll in EFTPS before you can use it; enrollment takes one to two weeks.

If you use a bank, the bank must be an authorized depositary for federal taxes. Most large banks are authorized. You provide the bank with a payment voucher (Form 8109, though this is now largely replaced by EFTPS) or use the bank's online system to initiate the deposit. The deposit is credited to the IRS on the date you submit it, provided you submit by the bank's cutoff time (usually late afternoon).

State deposits are made through your state's revenue or labor department, usually via their online portal or through an authorized bank. Check your state's website for the specific method and any required forms.

What happens if you miss a deadline

The IRS charges a failure-to-deposit penalty if you do not deposit on time. The penalty is a percentage of the unpaid tax and ranges from 2% to 15% depending on how late the deposit is. A deposit made one to five days late incurs a 2% penalty; a deposit made 16 or more days late incurs a 10% penalty; and a deposit made after the IRS sends a notice of intent to levy incurs a 15% penalty.

You also owe interest on unpaid taxes from the original due date until you pay. Interest is compounded daily and is set quarterly by the IRS.

The IRS has a safe harbor rule for small shortfalls: if you deposit within three business days of the deadline and the shortfall is no more than $100, the penalty may be waived. If you have a history of on-time deposits and can show reasonable cause for the late deposit, you may request penalty relief through Form 843 (Claim for Refund and Request for Abatement).

Penalties and interest for late filings

If you file a quarterly return (Form 941) or annual return (Form 940) after the deadline, the IRS charges a failure-to-file penalty of 5% per month (up to 25%) of the unpaid tax. If you file more than 60 days late, the minimum penalty is $435 (as of 2024, though this amount changes annually).

You also owe interest on any unpaid tax shown on the return. Interest accrues from the original due date, not from the filing date. If you file late but have already deposited all the tax owed, the penalty may be reduced or waived if you show reasonable cause.

State penalties for late filing and late payment vary by state. Most states charge a percentage penalty similar to the federal penalty, plus interest. Some states impose additional penalties for failure to pay state unemployment or disability insurance on time.

Frequently Asked Questions

What if I deposit on the right day but the bank processes it late?

The deposit is considered timely if you submit it to the bank by the bank's cutoff time on the due date. If the bank processes it after the deadline, the bank is responsible, not you — but you should confirm with the bank that it has a record of your timely submission. Using EFTPS eliminates this risk because the IRS credits the deposit on the day you submit it.

Do I have to use EFTPS, or can I use my bank?

You can use either EFTPS or an authorized bank. EFTPS is free and available 24/7, so many employers prefer it. If you use a bank, confirm that it is authorized to accept federal tax deposits and that you understand its cutoff times and fees (if any).

What if the due date falls on a weekend or holiday?

If the due date falls on a Saturday, Sunday, or federal holiday, the deadline moves to the next business day. For example, if a monthly deposit is due on a Saturday, you have until Monday to deposit. The IRS publishes a holiday calendar each year showing which dates are treated as holidays for deposit purposes.

Can I file Form 941 early?

Yes. You can file Form 941 before the deadline. If you file early and show an overpayment, you can request a refund or have the overpayment credited to your next quarter's taxes. Filing early does not change your deposit schedule — deposits are still due on their regular dates.

What if I owe payroll taxes but cannot pay by the deadline?

Contact the IRS or your state revenue department before the deadline to discuss payment options. The IRS offers short-term extensions (up to 120 days) and installment agreements. Requesting a payment plan before the deadline may reduce or eliminate failure-to-pay penalties, though interest still accrues.
