How The Gross Up Calculator Works

1
You Enter The Net Amount

You start by entering the exact net amount the worker should receive. This is usually the promised bonus or relocation payment after taxes.

2
You Choose Tax Rates

You set the type of payment and enter a federal, state, Social Security, and Medicare rate. For bonuses, you can use 22% federal plus 6.2% Social Security and 1.45% Medicare based on IRS supplemental wage rules.

3
The Tool Builds A Combined Tax Rate

The calculator adds your selected tax rates to create a combined withholding rate that applies to this payment. It does not replace a full payroll tax engine.

4
It Applies The Net ÷ (1 − Rate) Formula

Using the gross up formula Net / (1 − combined rate), the tool calculates the gross amount needed so that after the estimated tax withholding, the net equals your target.

5
You See Gross, Tax, And Effective Rate

The results show the gross payment, estimated tax by type, and the effective tax rate for this gross up, along with optional annualized views if the payment repeats.

This gross up calculator is a planning tool. For full paycheck detail use it together with the paycheck calculator, gross pay calculator, net to gross calculator, and bonus tax calculator.

Key Information About Gross Ups In 2026

Common Gross Up Scenarios

Situation Example Why Gross Up
Relocation bonus $5,000 net relocation payment Employer gross ups so the employee keeps $5,000 after tax on a taxable reimbursement.
Sign-on or retention bonus $2,500 net sign-on bonus Offer letter promises a clear take home amount instead of a gross number.
Year-end performance bonus $1,000 net bonus Employer covers federal supplemental tax so employees see a round net amount.
Taxable reimbursement Taxable moving allowance Employer pays enough to cover estimated taxes caused by the reimbursement.

In each case the gross up increases employer cost so the employee receives the same net payment after withholding.

Gross Up Formula Overview

Step Description Example
1. Choose net pay Pick the take home amount the worker should get. $700 net bonus.
2. Add up tax rates Combine federal income tax, Social Security, Medicare, and any flat state rate. 22% federal + 6.2% Social Security + 1.45% Medicare = 29.65%.
3. Convert to decimal Turn the combined rate into a decimal and subtract from 1. 1 − 0.2965 = 0.7035.
4. Divide net by result Divide net pay by (1 − combined rate) to get gross. $700 ÷ 0.7035 ≈ $995 gross.
5. Confirm tax and net Apply the rate to the gross and confirm the net equals your target. $995 × 29.65% ≈ $295 tax, $995 − $295 = $700 net.

This tool uses this same approach, similar to examples used by payroll providers such as ADP and OnPay, while keeping the math transparent.

Federal Bonus Withholding And 2026 Gross Ups

For many cash bonuses under current IRS rules, employers use a 22% federal supplemental wage withholding rate plus Social Security and Medicare. This means the combined rate for a bonus gross up is often close to 29.65% before any state tax. Larger bonuses or complex situations can trigger different treatment, so this calculator should be used as a planning estimate, not a final payroll or tax authority.

Gross Up Examples For US Workers

These examples show how a gross up can change employer cost so employees receive round dollar net amounts in 2026. Numbers are approximate and for illustration only.

Example 1

$700 Net Bonus Using Federal Supplemental Rates

  • Desired net bonus: $700
  • Federal income tax rate: 22%
  • Social Security: 6.2%
  • Medicare: 1.45%
  • State tax: 0%
Approximate Gross Up $995 gross

In this scenario about $295 goes to federal income tax, Social Security, and Medicare, leaving the $700 net bonus the employer promised.

Example 2

$5,000 Net Relocation Bonus With State Tax

  • Desired net payment: $5,000
  • Federal income tax rate: 22%
  • Social Security: 6.2%
  • Medicare: 1.45%
  • Flat state tax: 5%
Approximate Gross Up $7,100+ gross

The combined rate is close to 34.65%, so the employer must budget more than $7,100 gross to deliver a $5,000 net relocation payment after estimated taxes.

Example 3

Monthly Net Retention Bonus

  • Net amount per month: $300
  • Federal rate: 18%
  • Social Security: 6.2%
  • Medicare: 1.45%
  • State tax: 4%
Estimated Monthly Gross Up $430 gross

Over 12 months this adds up to roughly $5,160 gross in employer cost to deliver a $3,600 net retention bonus across the year.

These examples are simplified. Actual withholding depends on year-to-date wages, W-4 details, pre-tax deductions, and state and local rules. For full paycheck modeling, pair this tool with the paycheck calculator, net pay calculator, and bonus tax calculator.
