Updated July 27, 2026. Quick answer (2026): Moving from Michigan to Mississippi in retirement, you stop paying Michigan income tax on retirement withdrawals. Four separate taxes change when you move — state income tax on withdrawals, state estate tax, state inheritance tax, and what probate costs your heirs. Most comparisons only price the first one.
Michigan vs Mississippi: every tax that changes
| What changes | Michigan (leaving) | Mississippi (arriving) |
|---|---|---|

1. What changes on your annual tax bill
Michigan taxes retirement withdrawals: TY2026 completes the 4-year phase-in under PA 4 of 2023 (HB 4001): ALL taxpayers regardless of birth year may deduct retirement and pension income (pensions, 401(k), IRA) up to the Tier-1 cap — approximately $67,610 single / $135,220 joint for 2026 (indexed annually). Mississippi does not. On a $100,000 annual withdrawal, the Michigan bill is whatever its flat 4.25% schedule produces; in Mississippi it is $0. Social Security is treated as follows — Michigan: not taxed (fully deducted) Mississippi: not taxed (fully exempt)

Price the move against the rest of your money
A state-to-state comparison shows you which taxes change, not what to do about the accounts, the house and the timing sitting behind them, and an adviser can look at those together before a move is set in motion.
Before you start, what actually happens. The form is run by Kapitalwise, our advisor-matching partner. Kapitalwise sends your details to advisers who pay for the introduction, so expect calls and texts. Clear Money Guide is paid when you submit the form, whether or not you ever hire anyone. This is free to you and there is no obligation to hire anyone.
The Kapitalwise form opens here. You stay on this page.
What happens when you press the button
It asks about nine questions (age, investable assets, location), then your name, email and phone number, and verifies the phone by text. Nothing loads and nothing reaches Kapitalwise until you press the button. Submitting the form does not guarantee an adviser or a match. This matching form is not tax or legal advice.

4. The one nobody prices: what probate costs your heirs
Michigan uses a reasonable-fee fee model (EPIC: reasonable compensation for PR and attorneys (MCL 700.3719); no compensation percentage schedule. NOTE: Michigan does levy a value-scaled probate court ‘inventory fee’ on every estate (MCL 600.871) — see filing fees.); Mississippi uses a reasonable-fee model (Court’s discretion: ‘such sum as the court deems proper’ considering estate value/worth and difficulty of duties, plus necessary expenses including a reasonable attorney’s fee (Miss. Code §91-7-299). The old 1%-7% statutory guideline was removed by amendment; no percentage schedule today.). Filing fees — Michigan: $175 to commence probate proceedings, plus the value-based inventory fee under MCL 600.871 (e.g., $68.75 + 0.5% of the amount over $10,000 for estates $10k-$25k; continues scaling with estate value) — official Michigan Courts fee tables Mississippi: varies by county

Will Michigan still tax me after I move to Mississippi?
Not on your retirement withdrawals, once you genuinely change domicile — but that is a harder test than a change of address, and what you leave behind stays in reach.
- Domicile is a test, not a mailing address. A departing state can and does audit residency. Days present, voter registration, driver’s licence, where your doctors and advisers are, and where you keep what you value all count.
- A Roth conversion is taxed where you live in the year you convert. Sequencing a conversion after establishing the new domicile is often worth more than the annual saving — see how all 51 jurisdictions tax Roth conversions.

Talking this through
Relocation timing, Roth conversion sequencing and estate exposure interact, and the order you do them in changes the total. If you want a second opinion, understand what it should cost first — see our advisor cost guide. If a move is genuinely on the table, here is what to look for in an advisor who knows both Michigan and Mississippi.
