$100,000 Next-Day Deposit Rule: If you accumulate $100,000 or more in tax liability on any day during a deposit period, you must deposit the tax by the next business day, regardless of your regular deposit schedule. Failure to do so subjects the entire amount to FTD penalties.

Failure-to-File Penalty

Calculate penalties for late filing of payroll tax returns (Forms 941, 940, 943).

IRC § 6651(a)(1)

Enter total deposits and payments made by the original due date.

Form 944 is obsolete as of 2026.

Combined Penalty Cap: When both the Failure-to-File and Failure-to-Pay penalties apply for the same month, the Failure-to-File penalty is reduced by the Failure-to-Pay rate (0.5%) for that month. The maximum combined penalty for the first 5 months is 25% (22.5% filing + 2.5% payment). After 5 months, only the Failure-to-Pay penalty continues to accrue up to its own 25% maximum.

Failure-to-Pay Penalty

Calculate penalties for unpaid payroll tax liabilities after the due date.

Levy Warning: If the IRS issues a notice of intent to levy and the tax remains unpaid 10 days after that notice, the failure-to-pay penalty rate doubles from 0.5% to 1% per month. Act quickly to arrange payment or contact a tax professional.

Trust Fund Recovery Penalty (TFRP)

Calculate the personal liability for unpaid trust fund taxes assessed against responsible persons.

IRC § 6672
Personal Liability Warning: The TFRP is not just a business penalty. It is assessed personally against each responsible person — including officers, directors, shareholders, controllers, bookkeepers, and anyone with check-signing authority or the power to direct payment of funds. Each responsible person is individually liable for the full 100% of the trust fund taxes. Personal assets (home, savings, future wages) are at risk.

What are Trust Fund Taxes? Trust fund taxes are the employee portion of payroll taxes that employers withhold from employee wages and hold "in trust" for the government. They include: (1) federal income tax withheld, (2) the employee share of Social Security tax, and (3) the employee share of Medicare tax. The employer share of FICA is not considered a trust fund tax. The IRS considers failure to pay trust fund taxes as one of the most serious compliance violations.

Accuracy-Related Penalties

Calculate penalties for negligence, substantial understatement, or fraud on payroll tax returns.

IRC § 6662 / IRC § 6663

IRS Interest Calculator

Calculate compounded daily interest on unpaid payroll tax liabilities and penalties.

IRC § 6621

Enter the total unpaid tax (and penalties, if applicable — interest is charged on penalties too)

2026 underpayment rate: federal short-term rate + 3%. Currently approximately 8%.

IRS Interest Compounding: IRS underpayment interest is compounded daily at the federal short-term rate plus 3 percentage points. The rate is set quarterly by the IRS. Importantly, interest is also charged on penalties — so the total amount owed grows faster than many taxpayers expect. Interest cannot be abated except in cases of IRS error or delay.

Combined Penalty Scenario Builder

Many employers face multiple penalties simultaneously. Select which penalties apply to your situation to see your combined exposure.

Employee withholdings (SS + Medicare + FIT) — typically 60-75% of total payroll tax

Combined Penalty Scenario Analysis
Common Scenario: An employer who falls behind on payroll taxes often faces FTD + Failure-to-File + Failure-to-Pay penalties simultaneously. If trust fund taxes are involved, responsible persons also face personal TFRP liability on top of the business penalties. Interest compounds on all amounts. Early resolution is critical to limiting total exposure.
📅 Federal Tax Deposit Schedule Reference

Monthly Depositor

If your total tax liability during the lookback period was $50,000 or less, you are a monthly depositor. Deposits are due by the 15th of the following month.

Semi-Weekly Depositor

If your total tax liability during the lookback period exceeded $50,000, you are a semi-weekly depositor:

  • Saturday through Tuesday paydays: deposit by the following Wednesday
  • Wednesday through Friday paydays: deposit by the following Friday

Next-Day Deposit Rule

If you accumulate $100,000 or more in tax liability on any day during a deposit period, you must deposit the tax by the next business day. This rule applies regardless of whether you are a monthly or semi-weekly depositor. Once triggered, you become a semi-weekly depositor for the remainder of the calendar year and the following calendar year.

Lookback Period

For Form 941, the lookback period is the 12-month period ending on June 30 of the prior year (July 1 through June 30 of the two prior calendar years). The IRS uses your total tax liability reported on Forms 941 during this period to determine your deposit schedule.

Form 943 (Agricultural Employers)

Form 943 uses a separate lookback period: the second preceding calendar year. Agricultural employers follow the same deposit schedule rules (monthly vs. semi-weekly) based on their Form 943 liability.

Form 944 Obsolete

Form 944 (Employer's Annual Federal Tax Return) is obsolete as of 2026. Employers who previously qualified for and filed Form 944 must now file Form 941 quarterly. Ensure your deposit schedule is adjusted accordingly.

EFTPS Requirement

All federal tax deposits must be made electronically through the Electronic Federal Tax Payment System (EFTPS). Deposits made by other means (e.g., mailing a check with a deposit coupon) may be subject to a 10% penalty.

⚡ Penalty Relief & Abatement Options
First Time Abatement (FTA)

The IRS First Time Abatement policy provides relief from failure-to-file, failure-to-pay, and failure-to-deposit penalties if you meet the following criteria:

  • You have not previously been required to file a return, or you have no prior penalties (except an estimated tax penalty) for the preceding 3 tax years
  • You have filed all currently required returns or filed a valid extension
  • You have paid, or arranged to pay, any tax due

FTA is the most commonly used penalty abatement method and can be requested by phone, in writing, or using Form 843. It is administrative relief — it is not part of the Internal Revenue Code itself but is established by IRS policy (IRS Revenue Procedure).

Reasonable Cause

The IRS may abate penalties if you can demonstrate reasonable cause for the failure. You must show that you exercised ordinary business care and prudence but were nevertheless unable to comply. Common reasonable cause arguments include:

  • Death or serious illness of the taxpayer, immediate family member, or key person responsible for tax compliance
  • Natural disaster (fire, flood, hurricane, earthquake) affecting records or ability to comply
  • Inability to obtain records necessary to determine the tax due
  • IRS error or delay in providing necessary forms, guidance, or processing
  • Reliance on erroneous advice from a tax professional (must be documented)
  • Destruction of records through no fault of the taxpayer

Reasonable cause requests should be submitted in writing with supporting documentation. Use Form 843 (Claim for Refund and Request for Abatement) for formal requests.

Statutory Exceptions

Certain statutory provisions provide automatic penalty relief:

  • Reasonable cause and not willful neglect: IRC § 6651(a) provides that no penalty shall be imposed if the failure is due to reasonable cause and not willful neglect
  • Presidentially declared disaster areas: The IRS automatically extends filing and payment deadlines for affected taxpayers
  • Combat zone extensions: Military personnel serving in combat zones receive automatic deadline extensions
  • IRS postponement: The IRS may postpone deadlines for taxpayers affected by federally declared disasters or significant public health emergencies
Form 843: Use IRS Form 843 (Claim for Refund and Request for Abatement) to formally request penalty abatement. Include a detailed explanation of the circumstances, supporting documentation, and a timeline of events. Professional assistance from an experienced employment tax consultant can significantly improve the likelihood of a successful abatement request.
