SALT Cap Calculator 2025

If you're living in a high-tax state like California, New York, or New Jersey, the $10,000 SALT deduction cap can feel like a huge penalty. That’s exactly why we built saltcapcalculator.com — a simple, no-login tool to instantly estimate how much of your state and local taxes you'll lose under the current SALT cap rules. No spreadsheets, no login, no email. Just enter your numbers and get your estimate — it’s surprisingly eye-opening. We built this to help regular people make better year-end tax decisions (and maybe rethink where they live). Let us know what other scenarios you’d like to see supported!
