Purpose
Gross-up works backward. You decide the net amount an employee should take home, and UZIO calculates the gross pay needed to deliver it after taxes. Use it when you promise a specific in-hand amount.
Typical uses:
- A bonus where you want the employee to receive exactly, say, $1,000 after taxes
- A cash bonus or gift card given outside payroll that must still be reported on the W-2. Gross-up calculates the taxes on the flat amount.
Who can do this: Any user whose role includes the Payroll permission. This is usually the Employer Admin, but other admin roles can be granted the same access.
Prerequisites
- The earning you are paying (Bonus, Commission, and so on) exists at the company level as a flat-dollar taxable earning. See Company Level Earnings. Non-paid taxable earnings (cash tips, gift cards) also qualify if you are recording rather than paying them.
- Gross-up is available only in a Special Payroll, not in a regular run.
Steps
- Start a Special Payroll with Pay Run Type Special. Enter the pay group, the pay period start and end dates, and the pay date.
- Set Apply Deductions and Apply Contributions. For a gross-up run, No for both is usual (see limitations below), then continue.
- On the employee pay grid, zero out the auto-populated regular wages and hours. Special payrolls are usually for payments outside regular pay.
- Click the Gross-Up Net button on the grid toolbar. In the pop-up, set Enable Gross-Up Net to Yes, then pick the earning to gross up (for example, Bonus) under Select Earning Type. The list offers your non-hourly, taxable company earnings. If none exist, the selector is disabled with a message saying so.
- A Net to Gross column appears on the grid. For each employee who should receive a fixed net amount, enter it there. Their other earning columns show zero and UZIO recalculates their Gross Pay.
- Employees whose gross you already know can be paid normally in the same run. Leave their Net to Gross at 0. One pay run handles both.
- Click Continue, review the summary (the net for grossed-up employees matches what you entered), and approve.

Expected outcome
- Grossed-up employees receive exactly the net amount you entered. Taxes are calculated and withheld on the derived gross. For example, a $1,000 net bonus for an employee with a combined 30% withholding rate produces a gross of roughly $1,428.57, of which $428.57 is withheld. The pay stub shows the gross bonus and the taxes, and the direct deposit is $1,000.
- The payment lands on the W-2 correctly, including recorded-but-not-paid items such as gift cards.
- The employer cost is the gross amount plus employer taxes on it, shown on the run's cost summary.
Limitations and cautions
Warning: In these situations gross-up may not produce the intended result: - Multi-state employees where state income tax does not apply in the work state: do not select the supplemental flat rate for the run, or exclude those employees and run a separate special payroll without it. - Additional FIT/SIT withholding on an employee's W-4 should be removed for the gross-up run. Extra withholding skews the back-calculation. - 2% S-Corp shareholders: do not apply deductions or contributions in the gross-up special payroll.
Note: If you do apply deductions or contributions, anything other than the Fixed Dollar method is excluded from the net-to-gross calculation by default. To include one, add it manually on the pay grid as a one-time amount via Edit Deduction or Edit Contribution.
Note — blocked or overridden taxes: If Federal or State Income Tax is blocked for the run, no withholding is calculated at all, so gross-up has no tax to back into. Do not block those taxes on a gross-up run. If a tax is instead overridden (a flat $ or % on the employee's withholding setup), the overridden value is excluded from the gross-up calculation.
