IRS Form 944 (2021): Late & Amended Filing Guide
What IRS Form 944 (2021) Is For
Form 944 (2021) is the Employer's Annual Federal Tax Return designed for the smallest employers whose annual liability for social security, Medicare, and withheld federal income taxes is $1,000 or less (IRS Instructions for Form 944 (2021)). If the IRS notified you in writing to file Form 944 for 2021, you must file this form annually instead of quarterly Forms 941, even if your tax liability exceeded $1,000 that year.
When You'd Use Form 944 for 2021 (Late or Amended Filing)
You would file Form 944 for 2021 as a late or amended return in several scenarios. If you received IRS notices for unpaid employment taxes, you likely need to file the original 2021 return. Late filing situations typically arise when employers missed the January 31, 2022 deadline, often due to business changes, recordkeeping issues, or being unaware of the filing requirement. For amended returns, you would use Form 944-X to correct errors such as miscalculated wages, incorrect tax withholdings, or missed credits like the Employee Retention Credit or qualified sick leave wages that were significant in 2021. Note that refund statute limitations generally expire three years from the original due date, making April 2025 the deadline for most 2021 refund claims.
Key Rules Specific to 2021
The 2021 tax year included several unique provisions that differ from current rules. COVID-19-related credits were prominent, including qualified sick and family leave wage credits for leave taken both before April 1, 2021 (taxed at 6.2% for social security) and after March 31, 2021 (taxed at 12.4% for social security). The Employee Retention Credit was available with different calculations for wages paid before July 1, 2021 versus after June 30, 2021, with fourth-quarter 2021 eligibility limited to recovery startup businesses. The social security wage base was $142,800 for 2021. Additionally, employers could defer payment of the employer share of social security tax from 2020 with half due by December 31, 2021, and the remainder by December 31, 2022 (IRS Instructions for Form 944 (2021)).
Step-by-Step (High Level)
- Gather employment tax transcripts from the IRS by calling 800-829-4933 or using Form 4506-T to verify previously filed information and outstanding balances
- Obtain the correct 2021 version of Form 944 from IRS.gov/PriorForms, as current-year forms cannot be used for prior tax years
- Complete all five parts of the form using 2021 wage and tax data, including any applicable COVID-19 credits available that year
- For corrections, use Form 944-X separately; don't attach it to the original Form 944 unless reclassifying workers
- Mail paper returns to the processing center address specified in the 2021 instructions (electronic filing may not be available for prior years)
- Keep copies of all forms, supporting documentation, and proof of mailing or delivery for your records
Common Mistakes and How to Avoid Them
- Using the wrong form year: Always use the 2021 version of Form 944 for tax year 2021; current forms have different line numbers and requirements
- Incorrectly calculating COVID-19 credits: Use the specific 2021 worksheets (Worksheets 1-5) provided in the 2021 instructions, as credit calculations and tax rates differed throughout the year
- Mixing correction types: File Form 944-X separately for amendments; don't try to correct prior-year errors on a current-year return
- Missing the EIN or using incorrect business information: Verify your current Employer Identification Number and legal business name, as changes since 2021 must be properly documented
- Forgetting signature and date: Form 944 is invalid without proper signature from an authorized person and the correct date
- Inadequate record retention: Maintain all 2021 payroll records, as the IRS can examine returns for several years after filing
What Happens After You File
Processing times for prior-year returns typically take 12-16 weeks, longer than current-year returns due to manual handling requirements. The IRS will send acknowledgment notices confirming receipt and any balance due calculations. If you owe additional taxes, you'll receive a bill with penalty and interest calculations from the original due date. Payment options include installment agreements (Form 9465), which can often be established online for amounts under $50,000. If the IRS makes adjustments, you'll receive a notice explaining changes and have appeal rights through the Office of Appeals. For refunds, interest will be paid from the original due date, and the refund will be subject to offset against other federal debts. Keep monitoring your business tax account online or by calling 800-829-4933 for status updates.
FAQs
Can I still get a refund for my 2021 Form 944 if I file late?
Yes, if you file by April 2025 (three years from the original due date), you can claim refunds. However, there's no penalty for filing late if you're owed a refund, but you won't receive interest on refunds from late-filed returns.
What penalties apply to late filing of Form 944 for 2021?
The failure-to-file penalty is 5% of unpaid taxes for each month (or part of a month) late, capping at 25%. Failure-to-pay penalties are typically 0.5% per month. Interest accrues from the original January 31, 2022 due date at rates set quarterly by the IRS (IRS Instructions for Form 944 (2021)).
Do I need to file state employment tax returns if I file a late federal Form 944?
Federal and state employment tax obligations are separate. Contact your state tax agency to determine if you need to file late state returns, as requirements and deadlines vary by state.
Can I get tax transcripts for 2021 to help complete my late return?
Yes, request wage and income transcripts using Form 4506-T or by calling 800-829-4933. These transcripts show what the IRS has on file and can help identify any previously filed information or third-party reports.
What if I discover errors after filing my 2021 Form 944?
Use Form 944-X (Adjusted Employer's Annual Federal Tax Return) to correct errors. You generally have three years from the original due date or two years from when you paid the tax (whichever is later) to file corrections (IRS Instructions for Form 944-X).
Are the 2021 COVID-19 credits still available if I file late?
Yes, you can still claim eligible 2021 COVID-19 credits (Employee Retention Credit, qualified sick leave wages) when filing a late return, provided you meet all the original qualification requirements and use the correct 2021 calculation methods.
What if I can't pay the full amount owed with my late 2021 Form 944?
File the return on time to minimize penalties, then contact the IRS at 800-829-1040 to discuss payment options including installment agreements, offers in compromise, or temporary hardship status if you qualify.
