YouTube ad revenue tax calculator (2026)

What the calculator counts

Your channel's profit is the YouTube figure minus expenses. Self-employment tax applies first, using the same 2026 rules as the self-employment tax calculator: 92.35% of profit, 12.4% Social Security up to the $184,500 wage base (W-2 wages use part of it first), 2.9% Medicare, and the 0.9% Additional Medicare Tax once earnings pass $200,000 single or $250,000 joint, reduced by wages.

Income tax is the part people usually guess. The calculator works out your federal income tax twice, once with the channel and once without it, and the difference is what YouTube adds. Both runs use the 2026 standard deduction ($16,100 single, $32,200 joint) and rate schedules; the run with the channel also subtracts half of self-employment tax and takes the qualified business income deduction. That is why someone with a full-time job sees a higher rate per $1,000 than a creator with no other income: the channel's dollars land in a higher bracket.

The set-aside figure is the two taxes together, divided by your YouTube earnings and scaled to $1,000. Move that amount out of each AdSense deposit when it lands and the April bill is already covered.

Gross ad revenue or what YouTube pays you

YouTube Studio shows more than one revenue number. "Estimated revenue" is your share after the revenue split, from every source including memberships, Premium and Super Chat. "YouTube ad revenue" is gross, before the split. Google's partner earnings page sets the long-form watch-page share at 55% of net revenue, so the gross option multiplies by 0.55. Treat that as an approximation: Google applies the share to net revenue under its own definitions, so the result won't match Studio to the dollar. Shorts work differently: creators keep 45% of what a shared Creator Pool allocates to them, which can't be backed out of a gross figure. If your channel earns from Shorts or from anything besides ads, use the first option.

Studio's numbers are estimates and can be adjusted for invalid traffic or claims. The taxable figure is what Google actually pays you during the calendar year, which is what your 1099-MISC reports, so the AdSense payments report is the better input once you have it.

When Google withholds 24%

If no valid US tax info is on file, Google's YouTube help page says it may deduct up to 24% of total earnings worldwide as backup withholding. That money is not lost. It goes to the IRS as a federal tax payment, appears in box 4 of the 1099-MISC, and counts as tax already paid on your return. The calculator applies the full 24% to your YouTube earnings and subtracts it from the quarterly payments, but submitting the W-9 is the better fix: the withheld cash sits with the IRS until you file. Form by form, the filing side is in YouTube tax forms and how to file.

Creators outside the US are in a separate system, with 0 to 30% withheld on earnings from US viewers depending on tax info and treaty status, and this calculator does not cover it.

What it leaves out

State and local income tax is out of scope; where your state taxes income, add its share on top of the set-aside shown here. Also left out: credits such as the child tax credit, itemized deductions, the alternative minimum tax, capital gains, the 3.8% net investment income tax, head of household and married filing separately status, a spouse with a business of their own, and retirement contributions or self-employed health insurance, which would lower income tax. A loss (expenses above earnings) is treated as zero profit. Income tax withheld from a W-2 job is not counted, since it pays tax on the job, not the channel.

The four payments are an even split of what the channel adds. They are not the penalty safe harbor, which depends on last year's total tax. If some 2026 dates have passed, paying now still shortens the period the IRS charges a penalty on. For the safe harbor and every other income source in one place, use the quarterly estimated tax calculator.
