Gift Card Tax Gross-Up Calculator: What a Tax-Free-to-the-Employee Card Really Costs

The 2026 rates behind the presets

Every preset chip in the calculator is one of these figures. The federal and FICA rates come from the IRS's 2026 employer guides; the state rates are each state's own flat rate for supplemental pay (or, in Pennsylvania and Illinois, the single flat rate that applies to all compensation). They are withholding rates, not the employee's final tax bill: that is settled on their own return.

California splits supplemental pay in two, and the DE 44 does not name gift cards in either list. A card handed out as a sales or performance award reads most naturally as “sales awards” (6.6%); one paid as a year-end bonus reads as a bonus (10.23%). Ask your payroll provider which they apply — the table under the calculator shows both.

The gross-up formula

Grossing up means paying the employee's taxes for them. The catch is that the taxes you pay are themselves wages, which are taxed again. Publication 15-A puts it plainly for FICA: the employer's payment of the employee's share “is also subject to employee social security and Medicare taxes.” Solving that loop gives a simple division:

The calculator does not stop at the division. It searches for the smallest gross wage, in whole cents, whose take-home after each tax is rounded to the cent is at least the card value. That is why the example gives $400.31 rather than the $400.32 the raw division ($250 ÷ 0.6245 = $400.3203) would round to. The search also handles the two places the combined rate changes partway through a payment: the $184,500 social security wage base and the $200,000 Additional Medicare threshold.

Checked against the IRS's own example

Publication 15-A works one gross-up through for 2026: an employer pays a worker $500 and agrees to cover the worker's social security and Medicare. The IRS divides $500 by 0.9235 (1 − 0.0765) and reports $541.42 as wages, with social security tax of $33.57. Set the card value to 500 and the federal, state and other employee rates to 0, and the calculator shows a gross wage of $541.42, social security of $33.57 and Medicare of $7.85 — the same figures.

Worked example, line by line

The calculator opens on one employee in California who has been paid $68,000 so far this year and is getting a $250 gift card as a sales award. Forty colleagues get the same card. Federal withholding is the 22% flat rate, state withholding California's 6.6%, plus 1.3% SDI.

1. Combined employee rate: 22% + 6.6% + 1.3% + 6.2% + 1.45% = 37.55%. The employee is far below the $184,500 social security base and the $200,000 Additional Medicare threshold, so neither changes anything.
2. Gross wage: $250 ÷ 0.6245 = $400.32 by straight division; the cent-level search settles on $400.31.
3. Withheld from $400.31: federal $88.07, California $26.42, SDI $5.20, social security $24.82, Medicare $5.80 — $150.31 in total, which is exactly the gross-up. The employee keeps $250.00.
4. Employer's own FICA: $24.82 + $5.80 = $30.62. Cost of one grossed-up card: $400.31 + $30.62 = $430.93, or $1.72 for every dollar on the card.
5. Without a gross-up: the $250 card is the wage. The same rates take $93.88 from the employee's regular pay ($55.00 + $16.50 + $3.25 + $15.50 + $3.63), and your FICA is $19.13, so the card costs you $269.13.
6. Forty cards: $430.93 × 40 = $17,237.20 grossed up, against $269.13 × 40 = $10,765.20 — $6,472.00 more for the promise that nobody's paycheck shrinks.

Change only the state rate and the same card costs $389.76 grossed up in a state with no income tax, $457.53 at California's 10.23% bonus rate and $469.27 at New York's 11.70% (with the 1.3% SDI field still on; set it to 0 for states that don't levy it).

How to use the calculator

1. Enter the card value the employee should end up with.
2. Pick the federal rate. 22% is the flat rate for supplemental wages; use 37% only for an employee who has had more than $1 million of supplemental wages from you this year. If your payroll adds the card to a regular paycheck instead, enter the rate your provider tells you.
3. Pick or type the state rate, adding any city income tax, and any state disability or paid-leave contribution the employee pays.
4. Enter the employee's wages so far this year. High earners past the social security base cost less to gross up; above $200,000 the 0.9% Additional Medicare Tax is added.
5. Add the number of recipients to see the program total, and use Copy results for a plain-text summary to send to payroll.

Where gross-ups go wrong

• Grossing up for income tax only. Adding 22% to the card and stopping there leaves the employee short, because the extra 22% is taxed too. Divide, don't add.
• Forgetting your own FICA. The gross-up raises your 7.65% employer share as well; budget the employer cost, not the gross wage.
• Assuming small cards escape. Publication 15-B says gift cards, “no matter how little,” are never excludable as a de minimis benefit. A $25 card is wages like a $250 one.
• One rate for every state. The same card cost $389.76 to $469.27 in the example depending only on the state rate. Group recipients by state when you budget.
• Year-end timing. In December many employees are already past the social security base, which makes their gross-up cheaper — and a January card resets it.
