Verify the payroll-tax deposit schedule before changing next year's calendar

Ask the payroll tax specialist which lookback rule applies to the employer's filing history. Publication 15 distinguishes Form 941 filers from employers with relevant Form 943 or Form 944 history. The company's payroll frequency and expected next-year headcount do not establish its federal deposit schedule.

For an ordinary Form 941 filer reviewing 2026, the published lookback spans July 1, 2024 through June 30, 2025. Special filing-history rules can change that period. Record the contribution year being reviewed and the exact returns used so a calendar-year total is not substituted accidentally.

Retrieve the filed returns from the employer's records, including any periods handled by a former provider. A current-system report may contain only part of the lookback history. Confirm that each return belongs to the same employer and the intended period. Record any missing return explicitly and obtain the filed copy before approving the schedule determination.

Prepare a worksheet showing each relevant return, its original reported tax liability and the total used for the schedule determination. Publication 15 explains that adjustments on the applicable correction forms do not change prior-period liabilities for the lookback rule. Preserve corrected returns separately without substituting their figures automatically.

For the ordinary 2026 Form 941 lookback rule, the IRS distinguishes $50,000 or less from more than $50,000 of reported taxes. Verify the current rule and any exceptions for the year under review. A total close to the boundary deserves a second check of every included period.

Do not use cash deposits as a proxy for the reported liability. Payments can include corrections, late amounts or credits from another period. The schedule determination should be reproducible from the required return figures, with a separate explanation of any filing-history exception.

Ask the specialist about the next-day deposit rule and any resulting change in depositor status. A large bonus or other payment can trigger obligations different from the ordinary monthly or semiweekly timetable. The annual lookback worksheet should not be treated as permission to ignore those events.

Include unusual planned payrolls in the operational discussion, without confusing forecast amounts with the historical lookback calculation. Identify who monitors accumulated liabilities and notifies the payment team when a special rule applies. A provider and employer should not each assume the other is watching.

Confirm the current electronic payment cutoffs and holiday treatment used to implement the schedule. The legal deposit due date and the provider's submission cutoff may differ. Put both in the operating calendar so approval and funding can occur in time.

Retain the specialist's schedule determination, lookback worksheet and effective date. Update the provider configuration and internal calendar together. Ask for confirmation that quarterly reporting, including any Schedule B requirement, follows the revised status.

Review the first affected payroll from liability date through deposit completion. Confirm that an old recurring payment template or manual calendar reminder did not retain the former timetable. Save the payment evidence with the new schedule review.

Keep the annual determination accessible to the next payroll administrator, along with any midyear status change. Recalculate for each new year using that year's instructions. The record should show why the schedule applies, not merely repeat the setting inherited from the previous provider.
