QuarterlyTax1099 Calculator

Quarterly Tax 1099 helps freelancers, contractors, and self-employed workers estimate their federal estimated tax payments and avoid underpayment penalties. Enter your projected 1099 income, business expenses, other taxable income, filing status, withholding, tax credits, payments already made, and prior-year tax to receive a full breakdown of self-employment tax, adjusted gross income, standard deduction, federal income tax, and projected annual liability. The app applies the safe harbor rule automatically, shows both the 90 percent current-year and prior-year safe harbor bases, and calculates your required quarterly payment for whichever quarter is next due. Supports single, married filing jointly, and head of household filing statuses.
