Free · Tax year 2026

Free tax calculators

Free federal tax calculators for the situations that changed in 2026 — the SALT cap, the Child Tax Credit, the terminated EV credit, gambling winnings and losses, and bonus withholding. Each one runs the same calculation engine as the Spaife app.

New for 2026

SALT deduction capThe 2026 cap is $40,400 — but it phases down above ~$505k to a $10,000 floor. See your actual cap.
Child Tax Credit$2,200 per child, reduced $50 per $1,000 of income above the threshold. See your household amount.
EV tax creditTerminated for vehicles acquired after 30 September 2025. Check what a 2026 purchase gets.

Betting

Gambling losses (90% cap)You can owe tax in a year you lost money betting. See the phantom income and what it costs.
Gambling winnings & W-2GAll winnings are taxable even without a W-2G. See the tax yours add, and when a form is issued.

Pay & withholding

Bonus taxYour bonus is not taxed at 22% — that is withholding. See the rate that actually applies.
