Tax moves that matter most for Mississippi
If you own an S corporation, partnership or multi-member LLC, Mississippi's PTET election moves the Mississippi income tax on that profit to the business, where it is deductible federally and outside the SALT cap.
An S-corp election can cut self-employment tax once profit is large enough to pay yourself a reasonable salary and still cover payroll and filing costs. The Mississippi calculator adds Mississippi's own entity fees and taxes to that breakeven.
