Found a bracket typo? Want your city added? We read everything at [email protected] — or use the form below (it lands in the same inbox).
Is my salary stored? No. The calculator never uploads anything; the form only sends what you type into it.
How fast do you reply? Usually within a few days. Bracket corrections go first — they help every visitor.
Business or ads? Put “Partnership” in the subject line so it gets routed correctly.
Replies take a few days at most; corrections to published figures usually ship in the same week they are reported. We answer in the order received, with rate corrections first because they affect every visitor on that page.
Nothing you enter into a calculator is transmitted or logged — calculations run in your browser. When you write to us, we see only what you choose to put in the message.
We cannot review your return, advise on a specific filing position or represent you before a tax authority — for that you need a licensed professional in your jurisdiction. We also cannot give figures for situations the engine does not model (equity compensation, self-employment, rental income, multi-state filings).
Calculations never leave your browser, so we cannot see what you typed into a calculator — even if we wanted to. Only the message you send is visible to us.
Email is the only support channel: support@aftertaxlab.com. Messages are read in the order they arrive, and a reply normally takes two to three business days.
To make a reply possible in one round, include the URL of the page, the salary you entered, the state, and the filing status you selected.
Corrections are the most useful messages we get. If a figure looks wrong, send the page URL, the inputs, the number the site returned, and the number you expected — ideally with the source you are comparing against, such as a payslip, an IRS page or a state revenue department schedule.
Numbers that come from a misapplied rule are corrected and the affected pages are noted. Numbers that come from a genuine difference between our simplified model and a complex personal situation are answered individually, because a calculator cannot see your itemised deductions or credits.
AfterTaxLab does not provide tax, legal or financial advice, cannot prepare a return, and cannot answer questions about your personal filing position. The team is not made up of licensed tax professionals acting in that capacity for you.
Anything that requires a judgement about your circumstances belongs with a CPA, an enrolled agent or a licensed tax adviser who can see your full return.
The site carries Google AdSense advertising and a cookieless analytics beacon; neither is allowed to change a result. If you would like to embed one of the calculators on your own site, use the widget page and the embed code provided there — attribution is requested but no permission fee is charged.
For privacy questions, including access or deletion requests concerning the limited data described in the privacy policy, use the same address and put \"privacy\" in the subject line. We do not sell personal information, so a sale-opt-out request has nothing to act on, but it will still be answered.
Figures on this page are planning estimates built from published IRS tables and state agency rates; they are not tax advice. How we build and check these estimates · Edited by: Nuh Taspinar · Last updated: 2026-11-09
