Changelog
Every change to the tax rules behind these calculators, and every correction, newest first.
- Added the 2027 tax year, which starts on 1 January 2027: new federal brackets and standard deductions (IRS Revenue Procedure 2026-35) and the $192,300 Social Security wage base (SSA). The IRS has not announced the 2027 401(k) limit yet, so the 2026 limit ($24,500) is used for the cap until it does; affected results say so.
- Added head-of-household filing status using the brackets in IRS Revenue Procedure 2025-32.
- Launched the take-home pay calculators for the UK (2026/27), the US (2026, federal) and Australia (2026-27).
