Talk to a Specialist →Michigan’s treatment of retirement income depends on your birth year — one of the most confusing state tax rules in the country:
| Born | MI Retirement Income Tax | Move to AZ Impact |
|---|---|---|
| Before 1946 | Fully exempt (public + private pensions, SS) | AZ adds 2.5% on pensions/401k (income tax goes UP) |
| 1946–1952 | Partial exemption ($20K single/$40K couple) | AZ 2.5% flat may be lower on amounts above exemption |
| After 1952 | Taxed at 4.25% flat (same as wages) | AZ 2.5% saves 1.75% on retirement income |
The takeaway: if you were born before 1946, Michigan is actually more tax-friendly for retirement income than Arizona. If born after 1952, Arizona saves you 1.75% on every dollar of retirement income. The 1946–1952 cohort needs individual calculation.
Michigan’s retirement landscape is uniquely shaped by the auto industry. GM, Ford, and Chrysler/Stellantis pensions, along with UAW retiree benefits, represent the largest concentration of private-sector pensions in any state. Key considerations for auto retirees moving to Arizona:
Many auto retirees have employer-sponsored retiree healthcare that works with Michigan’s provider networks. Verify whether your retiree health plan covers Arizona providers at in-network rates. If not, you may need to transition to a Medicare Advantage plan with Arizona network coverage. Do this research BEFORE moving — a gap in coverage during the transition can be costly.
Pension income itself transfers seamlessly. Your monthly pension check arrives regardless of where you live. The only change is the state tax treatment — which depends on your birth year as described above.

| Michigan Home | After Selling (~7%) | Tucson $350K | Equity |
|---|---|---|---|
| $250K (outer Detroit suburbs) | $232K | $350K | -$118K needed |
| $350K (Oakland County/GR suburbs) | $325K | $350K | -$25K |
| $500K (Birmingham/West Bloomfield) | $465K | $350K | +$115K |
Most Michigan sellers need to target the $300K–$350K range in Tucson to break even on equity. Green Valley (Desert Hills from $175K, Canoa Ranch from $280K) offers the best value for Michigan buyers. Continental Ranch Sunflower at $360K with included golf is another strong match for Detroit-area auto retirees who want the most amenity per dollar.
