About
The 1099 tax calculator for freelancers, contractors, and gig workers: know how much estimated tax to set aside from every payment, and what quarterly tax to pay the IRS.
Self-employed? No one is taking taxes out for you. Holdback works out the share of every payment you should move to a tax savings account, and the four quarterly estimated payments to send the IRS, then reminds you before each deadline.
How it works
- Set your filing status, state, and roughly what you expect to earn.
- Log each payment as you get paid. Holdback tells you the dollar amount to set aside, rounded up so you're never short.
- See your running total, your effective rate, and what's due next quarter.
What it covers
- Federal self-employment tax and income tax, the standard deduction, and a conservative QBI deduction
- The No Tax on Tips and No Tax on Overtime deductions, with a daily tip log and a year-end statement to substantiate them
- State income tax for most states (flat and graduated)
- Safe-harbor math so you can pay the smaller allowed amount
- A year-end summary you can hand to your accountant
Built to respect your data
- Your income stays on your device. Cloud backup is optional.
- No bank connections. No ads. No selling your data.
Free: your set-aside rate, the quarterly plan, and the calculator.
Holdback Plus: payment tracking, deadline reminders, year-end export, and encrypted backup.
