Tax moves that matter most for District of Columbia
District of Columbia has no state income tax, so SALT cap concerns are limited to property tax. Optimization focus shifts to federal: 401(k), Mega Backdoor Roth, HSA, S-Corp election for self-employed.
At net SE income above ~$80k-$100k, electing S-Corp typically saves $5k-$15k/yr in self-employment tax — the math is largely federal but affects District of Columbia state tax via PTET (if applicable).
If you have 1099 income, Solo 401(k) lets you contribute up to $70,000/yr (2025) — far more than SEP-IRA in most cases. Reduces both federal and District of Columbia state income tax.
