Tax moves that matter most for Mississippi
If you have any pass-through business income (S-Corp, partnership, multi-member LLC), Mississippi allows the PTET election that effectively bypasses the federal SALT cap on the state income tax portion. Typical savings for high earners: $2k-$15k/year.
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 Mississippi state tax via PTET (if applicable).
If you have 1099 income, Solo 401(k) lets you contribute up to $72,000/yr (2026) — far more than SEP-IRA in most cases. Reduces both federal and Mississippi state income tax.
