Net to Gross Calculation

Overview

The Net to Gross Calculation feature in ProPay allows you to determine the gross pay needed to achieve a specific net pay amount for an employee. This is commonly called "grossing up" a paycheck. ProPay uses an iterative calculation engine that accounts for federal withholding, state withholding, FICA, Medicare, and all active deductions to arrive at the precise gross amount required.

When to Use Net to Gross

Use this feature when you need to guarantee an employee receives a specific take-home (net) amount:

  • Bonus payments where the employee should receive an exact dollar amount after taxes
  • Relocation reimbursements that need to cover the tax burden so the employee is "made whole"
  • Sign-on bonuses with a guaranteed net payout
  • Special one-time payments where the employer absorbs the tax cost
  • Year-end adjustments requiring a precise net amount

Accessing Net to Gross

  1. Go to Payroll Main Menu > Paychecks.
  2. Click Net to Gross on the Paychecks toolbar.

> Note: You must select a client and be on the Payroll Main Menu before the Paychecks menu is available.

Step-by-Step Procedure

Step 1: Select employees

  1. After clicking Net to Gross, ProPay displays the employee selection dialog.
  2. Select one or more employees by double-clicking their name or pressing Enter.
  3. Use Select All or Unselect All to manage large lists.
  4. Click OK to continue.

Step 2: Enter pay period information

  1. Enter the Pay Date, Period Ending, and Period Beginning dates.
  2. Select the Pay Frequency (Weekly, Bi-Weekly, Semi-Monthly, or Monthly).
  3. Click OK to proceed.

Step 3: Enter the desired net pay

  1. Enter the desired net pay amount the employee should receive.
  2. Optionally, check Zero Federal Tax to exclude federal withholding from the calculation.
  3. Optionally, check Zero State Tax to exclude state withholding from the calculation.
  4. Click Calculate to proceed.

Step 4: Review the results

ProPay performs an iterative calculation:

  1. It starts with an initial gross estimate based on the net amount plus estimated FICA and Medicare.
  2. It runs the full paycheck calculation engine (including all taxes and deductions) on that estimate.
  3. It compares the resulting net pay to your desired amount.
  4. If there is a difference, it adjusts the gross and recalculates.
  5. This process repeats up to three times until the net pay converges on your target.

The results screen displays:

  • The calculated gross pay required
  • All tax withholdings (federal, state, FICA, Medicare)
  • All deductions applied
  • The resulting net pay matching your target amount

Step 5: Use the calculated gross

Use the calculated gross pay amount when processing the employee's paycheck. You can enter it as regular pay or as a special pay type through the paycheck entry screen.

How the Calculation Works

ProPay's net-to-gross algorithm works as follows:

  1. Initial estimate: Gross = Net x (1 + FICA rate + Medicare rate)
  2. Full calculation: ProPay runs the complete tax engine on the estimated gross, computing federal withholding, state withholding, FICA, Medicare, and all scheduled deductions.
  3. Adjustment: If the calculated net pay differs from the target, ProPay increases the gross by the difference amount.
  4. Convergence: After up to three iterations, the gross amount is finalized. If federal withholding needs minor adjustment to achieve exact convergence, ProPay handles this automatically.

Important Notes

  • The calculation uses the employee's current tax settings, including filing status, allowances, and W-4 information. Verify these are correct before running net-to-gross.
  • All active deductions (401(k), health insurance, garnishments, etc.) are included in the calculation. If you need to exclude certain deductions, temporarily adjust the employee's deduction settings before calculating.
  • Net-to-gross calculations respect FICA and Medicare wage bases. If the employee is near the Social Security wage base limit, the calculation accounts for reduced FICA withholding.
  • Permission controls may restrict access to this feature for remote users. Contact your system administrator if you cannot access Net to Gross.

Common Questions

Q: Why does the calculated gross seem higher than expected?

A: The gross must cover not only the net pay but also all taxes and deductions. As the gross increases, taxes increase too, which is why the gross-up amount is always more than simply adding the tax amounts to the desired net.

Q: Can I run net-to-gross for multiple employees at once?

A: Yes. You can select multiple employees in the selection dialog. ProPay will calculate the required gross for each employee individually based on their own tax settings and deductions.

Q: What if I want to zero out taxes for the calculation?

A: Use the Zero Federal Tax and Zero State Tax options on the net pay entry screen. This is useful when the payment is not subject to certain taxes or when you want to see the gross amount without specific tax components.
