Payroll tax important date depend on how often you pay your employees and how much you owe

The IRS sets different due dates for payroll tax deposits based on your deposit schedule, which is determined by how much payroll tax you reported in a lookback period. Most small employers deposit payroll taxes either semi-weekly or monthly. The deposit important date is not the same as the filing important date — you deposit withheld taxes on a schedule throughout the year, then file a summary form (Form 941) quarterly.

If you miss a deposit important date, penalties and interest begin to accrue when ready. The IRS charges a failure-to-deposit penalty that ranges from 2% to 15% of the unpaid amount, depending on how late the deposit is. Knowing your specific schedule and marking those dates on a calendar is the most reliable way to stay current.

Key Takeaways

  • Semi-weekly depositors must deposit payroll taxes by Wednesday for payroll processed Monday through Wednesday, and by Friday for payroll processed Thursday through Sunday.
  • Monthly depositors must deposit all payroll taxes by the 15th of the following month.
  • Your deposit schedule is set by the IRS based on how much payroll tax you reported in the prior four calendar quarters (the lookback period).
  • Form 941 (Employer's Quarterly Federal Tax Return) is filed quarterly, not on the same schedule as deposits, and is due the last day of the month following the end of each quarter.
  • If you owe less than $2,500 in payroll taxes for a quarter, you may be able to pay with your Form 941 instead of making deposits.

How the IRS determines whether you deposit semi-weekly or monthly

The IRS assigns your deposit schedule based on the lookback period, which covers the four calendar quarters before the current year. If your total payroll tax liability during that lookback period was $50,000 or less, you are a monthly depositor. If it was more than $50,000, you are a semi-weekly depositor.

The IRS notifies you of your deposit schedule in writing, usually in the fall before the year it takes effect. If you are a new employer with no lookback period, you start as a monthly depositor. Your schedule can change from year to year depending on whether your payroll tax liability crosses the $50,000 threshold.

You can check your assigned deposit schedule by logging into your IRS online account through the Business Services Online portal, or by calling the IRS at 800-829-4933. Do not assume your schedule based on the size of your business — the IRS assignment is what matters.

Semi-weekly deposit important date and how they work

If you are a semi-weekly depositor, the IRS divides the week into two periods: Monday through Wednesday, and Thursday through Sunday. Payroll taxes withheld during Monday through Wednesday must be deposited by the following Wednesday. Payroll taxes withheld during Thursday through Sunday must be deposited by the following Friday.

The deposit important date is the date the money must arrive at the IRS, not the date you send it. If you deposit by electronic federal tax payment system (EFTPS) or through your bank's bill pay, allow at least one business day for the transfer to clear. If you are mailing a check, the IRS must receive it by the important date — mailing it on time is not enough.

Semi-weekly depositors often use EFTPS or payroll software that deposits automatically on the correct date to avoid missing important date. The IRS provides a semi-weekly deposit calendar each year showing the exact due date for each payroll period.

Monthly deposit important date and when they explore

If you are a monthly depositor, you deposit all payroll taxes withheld during a calendar month by the 15th of the following month. For example, payroll taxes withheld in January are due by February 15th. Payroll taxes withheld in December are due by January 15th of the next year.

Monthly depositors have more flexibility than semi-weekly depositors because they make fewer deposits and have a longer window to gather the funds. However, the 15th of the month is still a firm important date — weekends and holidays do not extend it. If the 15th falls on a weekend or federal holiday, the important date moves to the next business day.

Many small employers choose to deposit monthly payroll taxes at the same time they run payroll, even if the important date is weeks away. This reduces the risk of forgetting the important date and keeps the money separate from operating funds.

Form 941 filing important date and what they cover

Form 941 (Employer's Quarterly Federal Tax Return) is filed four times per year, not on the same schedule as deposits. It summarizes all payroll taxes withheld and paid during a three-month quarter. The quarters are January–March, April–June, July–September, and October–December.

Form 941 is due the last day of the month following the end of each quarter. The first quarter (January–March) is due April 30th. The second quarter (April–June) is due July 31st. The third quarter (July–September) is due October 31st. The fourth quarter (October–December) is due January 31st of the next year. If the due date falls on a weekend or federal holiday, the important date moves to the next business day.

Form 941 reconciles the deposits you made during the quarter with the actual tax liability. If you deposited more than you owed, the IRS credits the overpayment to your next quarter or refunds it. If you deposited less, you owe the difference when you file the form.

What happens if you miss a deposit important date

The IRS charges a failure-to-deposit penalty if you do not deposit payroll taxes by the important date. The penalty is a percentage of the unpaid amount and depends on how many days late the deposit is: 2% if it is 1 to 5 days late, 5% if it is 6 to 15 days late, and 10% if it is 16 or more days late. If the IRS has to send you a notice and the deposit is still not made within 10 days, the penalty increases to 15%.

In addition to the penalty, the IRS charges interest on the unpaid tax at a rate that changes quarterly. Interest accrues from the original due date until the date you pay. If you owe both payroll taxes and penalties, the penalties are calculated first, then interest is applied to the total.

If you realize you missed a important date, deposit the unpaid amount as soon as possible. The sooner you deposit, the less interest accrues. Contact the IRS if you believe you have a reasonable cause for the late deposit — the IRS may reduce or waive the penalty in some cases, though this is not automatic.

The $2,500 rule and when you can pay with Form 941 instead

If your total payroll tax liability for a quarter is less than $2,500, you do not have to make deposits during that quarter. Instead, you can pay the full amount when you file Form 941. This rule applies to both monthly and semi-weekly depositors.

For example, if you are a monthly depositor and you owe only $1,800 in payroll taxes for January, you do not have to deposit by February 15th. You can include that $1,800 with your Form 941 when you file it for the first quarter (due April 30th). However, if you owe $2,500 or more in any month during the quarter, you must deposit on your regular schedule for that month and all subsequent months in the quarter.

This rule is useful for very small employers or seasonal businesses with light payroll in certain months. However, it does not change your assigned deposit schedule — you are still a monthly or semi-weekly depositor for IRS purposes.

How to track your payroll tax important date throughout the year

The IRS publishes a deposit calendar each year showing every semi-weekly deposit important date. You can read it from the IRS website (irs.gov) or request it by phone. Many payroll software providers also display deposit important date in their systems and send automatic reminders.

A straightforward approach is to create a calendar entry for each important date at the beginning of the year. For monthly depositors, this means marking the 15th of each month. For semi-weekly depositors, use the IRS deposit calendar to mark each Wednesday and Friday important date. Set a reminder a few days before each important date so you have time to gather funds and process the deposit.

If you use a payroll service provider, ask whether they offer automatic deposits. Many providers can deposit payroll taxes on your behalf on the correct date, which removes the risk of missing a important date. You will still be responsible for ensuring the funds are available in your account.

Frequently Asked Questions

What if a deposit important date falls on a weekend or holiday?

The important date moves to the next business day. For example, if a semi-weekly deposit important date falls on a Saturday, you must deposit by Monday. If a monthly deposit important date (the 15th) falls on a Sunday, you must deposit by Monday. Federal holidays are treated the same way.

Can I deposit payroll taxes early?

Yes. Depositing early does not create any problems. The IRS will credit the deposit to the correct period based on the payroll dates you report. Early deposits can actually reduce the risk of missing a important date due to processing delays.

Do I have to use EFTPS to deposit payroll taxes?

No. You can deposit through EFTPS, your bank's bill pay system, or by mailing a check with a Form 8109 (Deposit Coupon). However, EFTPS and bank bill pay are faster and more reliable because they provide when ready confirmation. If you mail a check, allow extra time for it to arrive by the important date.

What if I cannot pay the full amount by the important date?

Deposit what you can by the important date to reduce penalties and interest. Then contact the IRS to discuss a payment plan. The IRS offers short-term agreements (up to 180 days) and long-term installment agreements for amounts you cannot pay when ready. Penalties and interest will still accrue, but setting up a plan shows good faith and may help if you need to request penalty relief later.

How do I know if I am a monthly or semi-weekly depositor?

The IRS sends you a written notice of your deposit schedule, usually in the fall before the year it takes effect. You can also check your schedule by logging into your IRS online account through Business Services Online, or by calling the IRS at 800-829-4933. Do not rely on what you think your schedule should be — use the IRS assignment.
