Filing Prior-Year Tax Forms After the Payroll Cutoff Date

Overview

This article explains the annual cutoff date for running prior-year payrolls in the system, why prior-year tax forms may stop populating after that date, and how to file the affected forms once the cutoff has passed. Use this guidance when tax forms for a prior tax year are not generating for a client and you need to determine the correct next step.

Understanding the Prior-Year Payroll Cutoff

The system enforces an annual cutoff for running or backdating payrolls for the prior tax year. The cutoff is typically February 28 of the following year (for example, February 28 of the year after the tax year being filed). After this date, the system will no longer accept new payrolls — including backdated Additional Payrolls — for the prior tax year, and prior-year tax forms will no longer populate automatically.

  • The cutoff applies to payrolls being run or backdated for the previous tax year.

  • Once the cutoff has passed, the system does not generate new tax forms for that prior year.

  • Confirm the current cutoff date with your firm's compliance resources or Support before assuming a form should still be available.

Before the Cutoff — Using an Additional Payroll to Backdate

Before the annual cutoff date, the recommended process for correcting or backfilling a prior-year period is to run an Additional Payroll backdated to the applicable pay date. This generates the tax liabilities and populates the tax forms for the affected quarter as expected.

  1. Select Additional Payroll as the payroll type.

  2. Set the Pay Period and Pay Date in Payroll Options to the applicable prior-year period.

  3. Enter the payroll information for each affected employee.

  4. Approve the payroll so the tax forms populate for that period.

This workflow is only available before the annual cutoff date. After the cutoff, the option to backdate payrolls to the prior year is disabled.

After the Cutoff — Filing Forms Externally

Once the annual cutoff has passed for a prior tax year, the affected tax forms cannot be generated or e-filed through the system. In this case, the forms must be prepared and filed manually outside the program.

  1. Obtain the appropriate blank tax forms from the applicable federal or state agency (or your firm's tax preparation software).

  2. Prepare the forms using the payroll data from the affected period.

  3. File the forms with the appropriate agency according to that agency's instructions.

  4. Retain a copy of each externally filed form in your firm's records so the filing history is documented.

Why Forms Do Not Populate After the Cutoff

The prior-year cutoff is a system-level control designed to close out payroll processing for the completed tax year. After the cutoff, the system prevents further changes to prior-year data — including new payrolls, backdated Additional Payrolls, and automatic form generation — to preserve the integrity of the year's records. This is a system limitation and cannot be bypassed on a case-by-case basis.

Tips for Avoiding This Situation Next Year

  • Track the annual prior-year payroll cutoff date each year and communicate it to your team well in advance.

  • Review each client's prior-year payroll and form status before the cutoff to identify any missing periods that still need to be entered.

  • If a client requires a backdated Additional Payroll for the prior year, complete it before the cutoff so the tax forms populate normally.

  • After the cutoff, immediately shift any outstanding prior-year filings to your firm's external filing workflow to avoid missed deadlines.

Key Takeaways

  • The system enforces an annual cutoff (typically February 28 of the following year) after which prior-year payrolls can no longer be run or backdated.

  • Before the cutoff, prior-year corrections should be entered through an Additional Payroll backdated to the applicable pay date.

  • After the cutoff, prior-year tax forms will not populate in the system and must be prepared and filed manually outside the program.

  • The cutoff is a system-level control and cannot be bypassed on a case-by-case basis.

  • Track and communicate the cutoff each year, and complete any prior-year corrections before the deadline.
