Form Overview

IRS Form 945A - Annual Record of Federal Tax Liability

IRS Form 945-A is the Annual Record of Federal Tax Liability used to report federal tax liability for certain filers. This form must be filed by semiweekly schedule depositors, and the threshold requiring a next-day deposit is $100,000.

The form collects your employer identification number (EIN) and business name at the top. It requires you to enter your tax liabilities by month in spaces corresponding to when wages/compensation were paid or nonpayroll payments were made, culminating in the total for line M.

Scan points
  • 1Ensure the total tax liability on Line M exactly matches the corrected amount on the accompanying Form 945, CT-1, or 944.
  • 2Filing without ensuring your EIN and name match those on the attached Form 945/CT-1/944.
  • 3Completing Form 945-A when the net tax liability for the return period is less than $2,500.
  • 4For monthly depositors, failing to file if you did not accumulate $100,000 in a month.
  • 5Entering tax liabilities based on accrual date instead of actual payment/wage date.

Plain English

This form shows the IRS how much federal tax an employer or business owes over the course of a year based on when payments were actually made. It acts as a yearly summary that must accompany other annual tax forms like Form 945. If you are required to file this, it confirms your total liability for the period.

Quick Facts

Form 945-A must be filed by semiweekly schedule depositors. Monthly schedule depositors become semiweekly depositors if they accumulate $100,000 or more of tax liability on any day of a calendar month.
The form collects your employer identification number (EIN) and business name at the top. It requires you to enter your tax liabilities by month in spaces corresponding to when wages/compensation were paid or nonpayroll payments were made, culminating in the total for line M.
Form 945-A must be filed every year with Form 945, CT-1, or 944 when those respective forms are due. The specific due date depends on which form it accompanies.
The instructions do not specify a single service center address for all filings. When filing, the form must be submitted with its accompanying Form 945, CT-1, or 944.
If you file late and owe tax, failing to use an amended Form 945-A can result in the IRS assessing an “averaged” Failure-to-Deposit (FTD) penalty. The total tax on line M must match corrected amounts from other forms.
First, enter your business EIN and name exactly as assigned by the IRS at the top of Form 945-A. Next, enter the calendar year to which the form is attached. Finally, detail your monthly tax liabilities in the corresponding spaces, ensuring the total on line M matches the totals reported on Forms 945, CT-1, or 944.

When should I file Form 945-A?
