2026 1099 Quarterly Tax Estimator
What the estimate includes
As of August 22, 2026, the tool uses 2026 federal ordinary-income brackets and standard deductions. It estimates self-employment tax on 92.35% of net profit, applies the $184,500 Social Security wage base after entered W-2 wages, and deducts half of estimated self-employment tax when approximating adjusted income.
What it deliberately leaves out
This is a planning estimate, not a tax return. It omits state and local tax, qualified business income rules, itemized deductions, many credits, additional Medicare tax, investment income tax, special new deductions, retirement contributions and uneven-income annualization.
Quarterly payments are not always one-fourth
Equal quarters are a cash-reserve target. Actual required installments can depend on prior-year safe harbor, current-year tax, withholding and when income was earned; use Form 1040-ES and Publication 505 or a qualified professional before paying.
Educational estimate only: changing filing status, a spouse’s income, credits or business deductions can materially change the result.
