I built a free calculator for the new US federal tax deduction on overtime pay. You type in your overtime hours and hourly rate, and it shows how much of the premium half you can deduct (up to $12,500 a year). There's also a W-2 mode. If your 2026 W-2 has Box 12 Code TT on it, you can enter that number directly. No signup, no email, everything runs in your browser. I built it because the official IRS examples are hard to follow and I wanted something plain and simple. https://www.myovertimetax.com/ Open to feedback on what's wrong or missing.   submitted by   /u/Delicious-Olive-2527 [link]   [comments]
