Quarterly Gig Tax Check

Fast answer first. Type a week of income, miles, and expenses, or import a CSV from your payout or business account, to estimate whether you likely owe quarterly taxes and what to move before the next due date for 2026.

CSV import, no bank loginUses 2026 mileage + federal rate tablesBuilt for quick quarterly checks, not full filing

1. Start fast

Use a preset if you want a quick benchmark, or import a CSV to reduce manual typing before you fine-tune the numbers.

Import a CSV instead

If you already have a payout or business-account export, this tool can estimate weekly averages from the observed date range without sending your statement anywhere.

Browser-only parsing
Upload a CSV to see the date range, total deposits, and estimated weekly averages before you apply them to the calculator.

2. Weekly numbers

3. Tax context

Filing status
Optional if you also have a W-2 job or already paid something

These fields matter because W-2 wages can already use up part of the Social Security wage base, and the amount already paid so far changes what may still be due by the next quarterly deadline.

Estimate only. This quick check excludes itemized deductions, credits, the QBI deduction, special 2026 deductions for tips or overtime, and local taxes. Recheck the number if your income changes materially during the year.

Mileage still moves the answer

The calculator annualizes your miles and applies the official 2026 IRS business rate before estimating tax.

$0

W-2 context changes the math

W-2 wages can already use up part of the Social Security wage base and can push gig profit into a higher federal bracket.

$0

Already covered tax changes the amount due now

Enter what you have already paid or withheld this year so the pace check does not double count it.
