Quarterly estimated taxes

Varies

Can You Write Off Quarterly Estimated Taxes?

Short answer: Federal estimated payments aren't deductible; state estimated income taxes count toward the SALT deduction if you itemize.

Federal payments are credited against what you owe.

Records to keep: Keep receipts, statements (1098, 1098-T, 1099, W-2G), and a note of what each cost was for. Compare itemizing to the 2026 standard deduction before you claim.
