- Take-home pay calculated using 2026 federal tax brackets (10%-37%), DC 2026 state income tax brackets after the standard deduction (top rate 10.8%), and FICA (Social Security 6.2% + Medicare 1.45%).
- Tax brackets and standard deduction ($16,100 single filer for tax year 2026) sourced from IRS Revenue Procedure 2025-32 and updated annually.
