What Counts as Gross Income From Tips and Commissions?

Tips and commissions both count as gross income from tips and commissions under federal tax law, meaning every dollar is taxable and subject to Social Security and Medicare tax the same way your regular wages are. The federal definition of gross income sweeps in all compensation for services, including fees, commissions, and similar items, so it makes no difference whether a customer handed you cash, a card tip appeared on your paycheck, or your employer paid you a percentage of what you sold.¹ What changes is how the income gets reported, when tax is withheld, and what you owe at filing time.

What Counts as a Tip

A tip is a voluntary payment the customer chooses to give, in an amount the customer decides, free from employer policy, and directed to the person the customer picks. All four elements have to be present.² That covers cash a customer hands you, amounts added to a credit or debit card slip, and your share of any tip pool or splitting arrangement.³

Non-cash tips count too. If a customer gives you concert tickets, a gift card, or another item of value, include the fair market value in your income for the year. Non-cash tips don’t get reported to your employer, but they still belong on your tax return.³

Mandatory charges added to a bill are not tips. Automatic gratuities on large-party checks, banquet service fees, and bottle service charges belong to the employer first, run through standard payroll, and are treated as regular wages for withholding.² Any portion your employer later pays you shows up on your pay stub with your hourly earnings rather than following the separate tip-reporting process.

What Counts as a Commission

Commission income is compensation tied to your sales rather than to your hours, and it is fully taxable gross income under the same statute that covers tips and fees.¹ It shows up in several common forms:

A percentage of each sale’s value or of your total sales volume for the period.
A flat dollar amount per completed transaction, regardless of the sale size.
A guaranteed base salary paired with performance-based pay.
A draw against commission, meaning an advance from your employer that gets deducted from future commission earnings. The draw itself is not extra income; it is an advance that must be reconciled against actual sales.

Performance bonuses tied to sales targets or company benchmarks belong in the same category. Whichever formula and pay cycle your employer uses, the full amount is taxable earnings for the period in which you earned it.

How the Tax Gets Applied

Tips and commissions are subject to federal income tax, Social Security tax at 6.2 percent, and Medicare tax at 1.45 percent, just like regular wages. When commissions and bonuses are identified separately from your regular pay, employers typically withhold federal income tax at a flat 22 percent rate. If your total supplemental wages for the year exceed $1 million, the excess is withheld at 37 percent.⁴

There is also an Additional Medicare Tax of 0.9 percent on combined wages, tips, and compensation above $200,000 for single filers or $250,000 for joint filers. Your employer begins withholding once your wages cross $200,000, regardless of your filing status, which means your final bill at filing can shift either direction depending on your household.⁵

Reporting Tips to Your Employer

You must report tips to your employer if you received $20 or more in cash and charge tips during any calendar month from a single job. Tips below that monthly threshold don’t need to be reported to your employer, though they still count as taxable income on your annual return.³

The deadline is the 10th of the month after the month you received the tips. If the 10th is a weekend or holiday, it moves to the next business day. Your report needs your name, address, Social Security number, your employer’s name and address, the month covered, and the total tip amount.³

Any written statement containing those elements works, as does an electronic system your employer provides. The IRS previously offered Form 4070 inside Publication 1244 for this purpose, but that publication is no longer in print. Content is what matters, not format.

A daily log is the best backup. Track the date, total cash tips, credit and debit card tips from employer reports, the names of anyone you shared tips with, and the amounts paid out in pooling arrangements.³

Filing Tips and Commissions on Your Return

Tips you reported to your employer show up on your W-2 alongside your regular wages, and you carry the combined total onto your Form 1040. Commissions earned as an employee work the same way.⁶

If you received tips of $20 or more in any month and didn’t report them to your employer, you still owe Social Security, Medicare, and any Additional Medicare Tax on those amounts. Use Form 4137 to calculate the tax and attach it to your Form 1040.⁷ You have to file a return in this situation even if your overall income would otherwise be low enough to skip filing.⁶

Sometimes your regular cash wages aren’t large enough for your employer to withhold all the Social Security and Medicare tax owed on your reported tips. This is most common when a big share of your pay comes from tips and your hourly wage is low. The uncollected amount appears on your W-2 in box 12 under codes A and B.⁸ You pay the shortfall yourself when you file by reporting the uncollected amount on Schedule 2 (Form 1040), line 13, which adds it to your total tax liability.⁹ A lot of tipped workers expect a refund and instead owe money because that gap follows them to the return.

The Tip Deduction for 2025 Through 2028

Starting with tax year 2025, workers who receive tips in occupations where tipping is customary may be eligible for a new federal income tax deduction on qualified tip income. The deduction runs through tax year 2028.¹⁰

It applies to cash tips you reported to your employer for payroll tax withholding purposes. Workers whose prior-year compensation exceeds a specified threshold, set at $160,000 in 2025 and adjusted for inflation in later years, aren’t eligible.¹¹ The deduction cuts income tax, but Social Security and Medicare taxes still apply to every dollar of tip income. Because specific rules and forms are still being finalized, check the current IRS guidance for your filing year before relying on it.

Commissions and Overtime

If you earn commissions and work more than 40 hours in a week, your commission income has to be built into your “regular rate” of pay for overtime. The regular rate isn’t just your hourly wage. It includes commissions earned during the workweek, divided by the total hours worked, to produce a blended hourly rate. Your overtime premium is calculated on top of that blended figure.¹²

When the commission can’t be calculated until after payday, which is normal with monthly or quarterly structures, your employer may initially pay overtime on the hourly rate alone. Once the commission is known, the employer must allocate it back across the workweeks when it was earned and pay any additional overtime owed.¹²

A narrow overtime exemption exists for commission-paid employees at retail or service establishments. Your regular rate has to exceed one and a half times the applicable minimum wage, and more than half your compensation over a representative period of at least one month must come from commissions. Both conditions have to be met, and the establishment itself must qualify as retail or service-oriented.¹³

Recovering Tax on Returned Commissions

Commission chargebacks create a familiar problem: you paid tax on money you later had to give back. Federal law addresses this through the “claim of right” doctrine. If you included commission income on a prior year’s return because you reasonably believed you had an unrestricted right to it, and you later repaid the money, you can recover the tax.¹⁴

The treatment depends on the amount you repaid. If the repayment is $3,000 or less, you deduct it in the year you made it, on the same form or schedule where the income was originally reported. If the repayment is more than $3,000, you choose whichever method produces the lower tax: deducting the repayment in the current year, or taking a credit equal to the tax reduction you would have gotten by excluding the income from the prior year’s return.¹⁴

Keep any notices or documents showing the repayment amount, proof that you actually paid it back (canceled checks, pay stub deductions, bank statements), and the return from the year you originally reported the income. For large chargebacks, running the numbers both ways is worth the time; the credit method often saves significantly more than a simple deduction.

Penalties for Underreporting

If you fail to report tips to your employer as required, the IRS can impose a penalty equal to 50 percent of the Social Security, Medicare, and Additional Medicare taxes owed on the unreported amounts. That is separate from the income tax you also owe on the same tips. You can avoid the penalty by attaching a statement to your return showing the failure was due to reasonable cause rather than intentional neglect.⁸

Underreporting any type of income, tips or commissions, can also trigger a separate accuracy-related penalty of 20 percent of the resulting tax underpayment if the IRS finds negligence or disregard of the rules. The penalties stack. A tipped worker who consistently underreports can end up owing the original tax, the 50 percent FICA penalty, and the 20 percent accuracy penalty at once, which is why the daily tip log matters.
