Payroll Tax Deposit Schedule Calculator

The calculator first determines the base federal deposit schedule from the entered lookback-period tax liability. A lookback amount of $50,000 or less generally produces monthly depositor status. A lookback amount above $50,000 generally produces semiweekly depositor status.

It then applies the payday rule. Monthly deposits are generally due by the 15th day of the following month. Semiweekly deposits are due the following Wednesday for Wednesday-Friday paydays and the following Friday for Saturday-Tuesday paydays. Weekend and legal-holiday due dates move to the next business day.

Finally, the calculator checks two special rules: the $100,000 next-day deposit rule and the small-liability pay-with-return exception. It also estimates the basic failure-to-deposit penalty tier when the planned deposit date is after the modeled due date.

Deposit schedule is not chosen payroll by payroll

Federal payroll tax deposits are based on employer status, not preference. For most Form 941 employers, the lookback period decides whether the employer is a monthly or semiweekly schedule depositor for the calendar year. A new employer generally starts with a zero lookback tax liability, which usually means monthly depositor status until a special rule changes the schedule.

The lookback period for Form 941 is the 12-month period ending on June 30 before the calendar year. For example, 2026 deposit status is generally based on taxes reported from July 1, 2024 through June 30, 2025. Annual employment tax return types use a calendar-year lookback period instead.

Monthly deposit rule

Monthly schedule depositors generally deposit employment taxes accumulated during a calendar month by the 15th day of the following month. If the 15th falls on a Saturday, Sunday, or legal holiday, the deadline moves to the next business day. This calculator applies those business-day adjustments before showing the due date.

Monthly depositor status does not mean the employer deposits once per quarter. A Form 941 monthly depositor may still have up to three federal deposit due dates inside one quarter, one for each month in which payroll tax liability is accumulated.

Semiweekly deposit rule

Semiweekly schedule depositors use payday timing. If wages are paid on Wednesday, Thursday, or Friday, the deposit is generally due by the following Wednesday. If wages are paid on Saturday, Sunday, Monday, or Tuesday, the deposit is generally due by the following Friday. The rule is called semiweekly, but it does not mean deposits happen exactly twice every week.

Semiweekly depositors must track liabilities by day, not merely by month. For Form 941, that often means completing Schedule B with daily tax liability detail rather than using only the monthly line 16 summary.

The $100,000 next-day rule changes the answer fast

The $100,000 rule is a common payroll deposit trap. If an employer accumulates $100,000 or more in employment tax liability on any day during a deposit period, the deposit is generally due by the next business day. A monthly depositor that triggers the rule becomes a semiweekly depositor for the rest of that calendar year and the following calendar year.

Large bonuses, equity compensation, seasonal payroll spikes, acquisitions, and year-end payroll runs can trigger the next-day rule even when the employer normally has a slower deposit schedule. Use the liability input to test the largest daily or deposit period liability, not only ordinary wages.

Small-liability payment with return

Some small employers can pay employment taxes with a timely filed return instead of making a separate federal tax deposit. The most common planning threshold is a current return-period liability under $2,500. This calculator treats that as a possible exception and keeps the regular deposit due date visible so you can compare both dates.

Do not use the small-liability shortcut if the return-period tax is not truly under the threshold, if the return will not be timely, or if the $100,000 next-day rule applies. Payroll software may also require deposits based on your actual liability history and return setup.

Failure-to-deposit penalty tiers

The IRS failure-to-deposit penalty generally starts at 2% for deposits one to five days late, 5% for deposits six to fifteen days late, and 10% for deposits more than fifteen days late. A 15% penalty can apply after IRS notice and demand if the tax is still not paid. This calculator estimates only the basic date-based tier from the planned payment date.

If your deposit is late, review the IRS penalty and interest calculator for broader penalty modeling, the late filing and late payment penalty calculator for return-balance penalties, and the FICA tax calculator for Social Security and Medicare components.
