Mississippi Tax Quick Facts (2026)
Tax Overview for Mississippi Business Owners

Mississippi State-Specific Tax Details (2026)
Pass-Through Entity (PTE) Tax Election
Yes. Mississippi has an elective Pass-Through Entity Tax (enacted by HB 1691, signed April 2022, effective for tax years beginning on/after Jan 1, 2022). Partnerships, S-corps, and similar PTEs elect on Form 84-381; greater than 50% of voting owners must consent and the election applies to all owners (cannot be made owner-by-owner). The election is made by the 15th day of the 3rd month following the close of the tax year and, under current DOR guidance, is binding for that year and subsequent years until revoked (revocation also via Form 84-381). The electing entity pays tax at Mississippi's highest marginal individual income tax rate - a flat 4% on income over $10,000 for tax year 2026 - and owners receive a credit for their pro-rata share of the entity tax, allowing the state tax to be deducted at the entity level and bypassing the federal $10,000 SALT cap. Confirm the current entity rate and election mechanics against live DOR EPTE guidance before filing.
Local & City Income Taxes
None. Mississippi has no county or municipal income taxes; only state income tax applies. The only local levies are local-option sales taxes and tourism/economic-development (hotel/restaurant) taxes.
Entity-Level & Franchise Taxes
Mississippi imposes a corporate franchise tax on C-corps and S-corps (LLCs exempt unless taxed as a corporation). It is being phased out: the rate is $0.50 per $1,000 of capital in excess of a $100,000 exemption for 2026 (down from $0.75 in 2025), with full repeal for tax years beginning on or after Jan 1, 2028. The corporate income tax is a flat 4% on income above $10,000 for 2026. Mississippi recognizes the federal S-election (taxing income at the shareholder level); S-corps still file the franchise tax until repeal and may make the PTE election.
Mississippi Tax Credits & Incentives
An income tax credit equal to 2.5%/5%/10% of payroll per net new job (rising with less-developed county tiers) for businesses in manufacturing, processing, distribution, R&D, wholesaling, or warehousing that create the minimum number of new jobs for their tier (20/15/10). The credit runs for five years, generally starting the second year after the jobs are created.
An income tax credit of $1,000 per year for each full-time position requiring research and development skills (e.g., chemists, engineers) located in Mississippi, available for a five-year period to offset Mississippi income tax.
A single-application program awarding one consolidated, flexible Mississippi tax credit that a qualifying company can apply against income, franchise, sales/use, and payroll withholding tax (withholding offset capped at 20% per year). Aimed at new/expanding businesses with planned capital investment over $2.5M creating 10+ jobs.
For 2026, model the PTE election against Mississippi's falling rates: the PTE entity rate equals the highest individual rate, a flat 4% on income over $10,000 for 2026, while the corporate franchise tax is down to $0.50/$1,000 (over a $100,000 exemption) and is fully repealed Jan 1, 2028. If you run an S-corp, 2026-2027 is the last window of franchise-tax exposure, so don't accelerate capital-based exposure expecting it to persist. The individual/PTE income tax is scheduled to step down toward 3% by 2030 with possible later elimination - but those later cuts and the eventual phase-out are contingent on state revenue/spending triggers, not automatic, so weigh accelerating PTE deductions now (while the federal SALT cap benefit applies) against deferring income into potentially lower-rate years. Consult a Mississippi tax professional before acting.
Top Tax Strategies for Mississippi Business Owners
Mississippi offers a moderate tax environment. While state taxes are manageable, combining federal and state strategies can still save you thousands each year.
Income tax being phased out
S-Corp salary optimization
Focus on federal strategies
S-Corp Election in Mississippi
For Mississippi business owners with net income above $50,000, electing S-Corp status can save $5,000 to $20,000+ annually in self-employment taxes. As an S-Corp, you pay yourself a "reasonable salary" and take the remaining profits as distributions, which are not subject to the 15.3% self-employment tax. Keep in mind that Mississippi's 0% - 5% (phasing out) income tax still applies to both your salary and your distributions, so the S-Corp election saves you federal self-employment tax while your state planning shifts to deductions, retirement contributions.
Example: A Jackson S-Corp
A Jackson business owner earning $150,000 in net business income pays themselves a reasonable salary of $60,000. The remaining $90,000 in distributions avoids the 15.3% SE tax, saving $13,770 in self-employment taxes alone — on top of whatever your Mississippi state planning adds.
Retirement Plan Strategies for Mississippi
Retirement plan contributions are the single most powerful tax deduction available to Mississippi business owners. A Solo 401(k) allows contributions up to $69,000 in 2026 ($76,500 if you're 50+), generating tax savings of $17,000 to $24,000 at a 25-32% effective tax rate. For Mississippi owners, those contributions cut both your federal bill and your 0% - 5% (phasing out) state income tax, stacking the savings.
SALT Deduction Impact in Mississippi
Declining SALT impact as rates decrease. The federal SALT (State and Local Tax) deduction cap increases from $10,000 to $40,000 in 2026, providing meaningful relief for business owners in states with income taxes.
