Michigan Tax Calculator 2026: 4.25% Flat Tax + Full Retirement Exemption
Michigan's 4.25% flat income tax stays in 2026 (formally confirmed April 15, 2026 by State Treasurer Eubanks). The Lowering MI Costs Plan reaches its full 100% retirement income exemption this year, and Public Act 24 of 2025 adds a new Social Security + standard deduction stacking option for age-67+ filers. Calculate your 2026 take-home pay including federal brackets, MI state tax, 24-city local tax structure (Detroit 2.4%, Grand Rapids 1.5%), and FICA — with primary-source data verified against the Michigan Department of Treasury.
What is Michigan's income tax in 2026?
Michigan has a flat 4.25% income tax for 2026, unchanged from 2025. State Treasurer Rachael Eubanks formally announced on April 15, 2026 that the statutory rate-reduction formula in Section 51 of the Michigan Income Tax Act did not trigger — general fund revenue actually decreased 1.56% during fiscal year 2025 while inflation rose 2.70%, so the conditions for a cut were not met. Michigan's rate has been 4.25% since 2012 (briefly 4.05% for tax year 2023 as a one-time formula-driven reduction that the Michigan Supreme Court ruled was temporary).
The big 2026 story is retirement income. The Lowering MI Costs Plan (Public Act 4 of 2023) reaches the final phase of its four-year ramp this year — taxpayers born after 1945 with qualifying retirement income (pensions, IRA distributions, 401(k) withdrawals) get a 100% exemption in 2026, up from 75% in 2025, 50% in 2024, and 25% in 2023. The 2026 maximum private + public benefit subtraction is approximately $65,987 single / $131,794 married. This essentially restores the pre-2012 retirement subtraction Michigan removed under Gov. Snyder. Plus, Public Act 24 of 2025 adds new flexibility for age-67+ filers: they can now claim BOTH the standard deduction AND the Social Security deduction (previously either/or). Social Security has been fully exempt at the state level throughout this period — Michigan does not tax Social Security regardless of age or income.
The complete 2026 Michigan tax picture: federal + state + city + FICA
Michigan's total tax burden has up to four layers: federal income tax, MI state flat tax at 4.25%, city local income tax (if you live or work in one of 24 taxing cities), and FICA. These tables use primary-source data verified against the IRS, the Michigan Department of Treasury, and the Social Security Administration.

2026 Michigan take-home pay across common salary levels
These figures show estimated take-home pay for a single filer in Detroit (2.4% city tax) — Michigan's highest city tax. Living in Ann Arbor, Troy, or another non-taxing city saves approximately 2.4% of gross salary per year. Living in Grand Rapids saves about 0.9% versus Detroit. Married filing jointly increases take-home by roughly 3-8% depending on bracket.
| Gross Salary | Federal Tax | MI State (4.25%, $5,800 exemption) | Detroit 2.4% Local | FICA (7.65%) | Annual Take-Home |
|---|---|---|---|---|---|
| $40,000 | $2,620 | $1,454 | $960 | $3,060 | $31,906 (79.8%) |
| $50,000 | $3,820 | $1,879 | $1,200 | $3,825 | $39,276 (78.6%) |
| $60,000 | $5,020 | $2,304 | $1,440 | $4,590 | $46,646 (77.7%) |
| $75,000 | $7,670 | $2,941 | $1,800 | $5,738 | $56,851 (75.8%) |
| $100,000 | $13,170 | $4,004 | $2,400 | $7,650 | $72,776 (72.8%) |
| $125,000 | $18,734 | $5,066 | $3,000 | $9,562 | $88,638 (70.9%) |
| $150,000 | $24,734 | $6,129 | $3,600 | $11,475 | $104,062 (69.4%) |
| $200,000 | $36,734 | $8,254 | $4,800 | $14,339 | $135,873 (67.9%) |
Calculations assume one personal exemption ($5,800), no Lowering MI Costs Plan retirement subtraction (working-age scenarios), no pre-tax 401(k) or HSA contributions, and 0% additional withholding. Real take-home will be higher if you contribute to a traditional 401(k), HSA, or HDHP. Federal tax uses 2026 IRS brackets and $16,100 standard deduction for single filers. Michigan state tax uses the 4.25% flat rate after Michigan personal exemption. Detroit local at 2.4% on gross wages. FICA uses 6.2% Social Security (capped at $184,500 in 2026 per SSA) plus 1.45% Medicare (no cap). Non-Detroit cities reduce or eliminate the local tax column.
The Michigan tax decision matrix: what to do based on your situation
Michigan's 2026 tax landscape creates different optimal moves depending on your age, where you live and work, and whether you have retirement income. Match your situation to the right first move.
2026 is the year — full 100% retirement exemption arrives. Under the Lowering MI Costs Plan (Public Act 4 of 2023), qualifying retirement income (pensions, IRA distributions, 401(k) withdrawals) is now fully exempt from MI state tax, up to $65,987 single / $131,794 MFJ. After three years of phase-in (25%/50%/75%), the law essentially restores the pre-2012 retirement subtraction. File Schedule 1 with MI-1040. Update withholding via your pension administrator — MERS, ORS, and federal pensions have all updated 2026 forms.
Public Act 24 of 2025 changed the math for 2026-2028. Previously, taxpayers born after 1952 who took the $20,000 single / $40,000 MFJ standard deduction at age 67 had to reduce it by their Social Security deduction (effectively either/or). Now they can stack both. Run the two calculations: (1) Lowering MI Costs Plan retirement subtraction + Social Security exemption + personal exemption, vs (2) the $20K/$40K standard deduction + Social Security deduction. Take whichever produces lower Michigan taxable income.
The Detroit decision is worth 2.4% of gross income. Detroit residents pay 2.4% city tax on all compensation. Move 15 minutes north to Ferndale, Royal Oak, or Berkley (none of which levy local income tax) and you keep that 2.4%. At $75K salary, that's $1,800/year. Over a 30-year career, $54K of after-tax savings. Compare to: Highland Park 2.0%, Grand Rapids 1.5%, Lansing/Flint/Pontiac 1.0%, Ann Arbor/Troy/Dearborn $0. If you change jobs, also check your work city — non-residents pay half the resident rate on income earned within taxing cities.
State reciprocity applies but city reciprocity does NOT. Michigan has reciprocal income tax agreements with five neighboring states — you only owe state tax to your home state. But MI city income taxes (Detroit, Grand Rapids, etc.) are NOT covered by reciprocity. If you live in Toledo, OH and commute to Detroit, you still owe Detroit's 1.2% non-resident tax on Detroit-earned wages even though Michigan state tax is exempted under MI-OH reciprocity. Confirm withholding with payroll and file MI-1040 nonresident schedule.
File the PRE affidavit — it's not automatic. The Principal Residence Exemption removes the ~18-mill school operating tax from your primary residence — a typical $300K home in Wayne County saves $5,400/year on property tax just from the PRE filing. Submit the affidavit to your local assessor within 95 days of closing or you miss the current year's benefit. Also evaluate the Homestead Property Tax Credit if your household resources are below $69,700 and your home's taxable value is under $165,400.
Michigan partially adopted OBBBA — overtime and tips are deductible. Unlike North Carolina (which adopted none of the OBBBA provisions), Michigan's 2025-2026 budget (PA 24 of 2025, signed October 7, 2025) adopted federal deductions for qualified overtime wages and qualified tip income on the Michigan return, available 2025-2029. The federal senior $6,000 deduction and auto loan interest deduction were NOT adopted. Tip and overtime workers in MI get a meaningful state tax break beyond the federal benefit. Verify on MI-1040 Schedule 1.
Three small moves that change your Michigan tax bill
Michigan's flat tax simplifies the planning, but three specific moves still have meaningful dollar impact. Each requires under an hour of effort.
-
Max out pre-tax 401(k) and HSA contributions to reduce federal AND Michigan taxable income. Every dollar contributed to a traditional 401(k) reduces federal taxable income (saving 22-32% federally) AND Michigan taxable income (saving 4.25%). The 2026 401(k) employee limit is $23,500 ($31,000 if age 50+); HSA limits are $4,300 single / $8,550 family. Detroit residents also save 2.4% city tax on the contribution.
Impact: maxing 401(k) alone saves ~$999 in MI state tax annually (at $23,500 × 4.25%) plus ~$564 in Detroit city tax if applicable, plus federal savings of $5,000-$8,500.
-
If you live in Detroit and considering a move, check non-taxing suburbs that match your commute. Detroit's 2.4% city tax on $75K = $1,800/year permanently saved by moving to Ferndale, Royal Oak, Berkley, Hazel Park, or Madison Heights — all within 15-20 minutes of downtown Detroit. Even cheaper: Ann Arbor, Troy, Dearborn, Sterling Heights, Warren, Livonia, Novi all charge $0 in local income tax.
Impact: moving from Detroit to non-taxing Royal Oak at $75K salary saves $1,800/year permanently. Over a 30-year career, that's $54K of after-tax savings before investment growth.
-
If retired with pension or IRA income, claim the full 2026 Lowering MI Costs Plan retirement subtraction. Born after 1945 → 100% exemption up to $65,987 single / $131,794 MFJ for 2026. This is a state-level subtraction on MI-1040 Schedule 1 that is separate from your federal return. Many retirees still have withholding from pension administrators using pre-Lowering-MI-Costs defaults — update your withholding election via MERS, ORS, or your federal pension administrator to stop over-withholding.
Impact: a $50,000/year pension fully exempt saves $2,125/year ($50,000 × 4.25%) — every year for life, with no income or asset cap.
The Lowering MI Costs Plan: what 2026's full exemption is actually worth
Michigan retirees lived under the post-2012 retirement tax for over a decade — Gov. Snyder's 2011 reform that subjected most pension and retirement income to the 4.25% flat tax. Public Act 4 of 2023 reversed that policy in four annual steps. 2026 is the year the reversal finishes. These figures show the real dollar value of the change at common retirement income levels.
Compare to other Midwest states for retirement income. Michigan's 2026 retirement tax picture is now competitive: 0% on Social Security + 0% on qualifying pensions/IRAs under the Lowering MI Costs Plan (for those born after 1945) = no MI state income tax on most retirement income for most retirees. Compare to Ohio at 2.75% flat (Social Security exempt, but pensions and IRAs taxed); Indiana at 3.05% flat (most retirement taxable above small deduction); Wisconsin at graduated 3.5%-7.65% (pensions and IRAs taxable with limited exemptions). Michigan is now meaningfully more retirement-friendly than its neighbors among states that still levy any income tax — and far better than non-flat states like Minnesota (top rate 9.85%).

The daily cost of Detroit vs Michigan suburbs: the city-tax math
Michigan's combined state + city tax structure creates one of the largest within-state geographic tax differentials in the country. Where you live inside Michigan changes your paycheck by 0-2.4% of gross — meaningful money over a career. Here's the daily cost math.
The bigger pattern: Michigan's 24-city local tax structure is the second-most-extensive in the Midwest (after Ohio's 600+ taxing municipalities) but is concentrated in older industrial cities — Detroit, Flint, Pontiac, Highland Park, Lansing, Saginaw. Modern suburbs and most newer cities never adopted local income tax. This creates a tax-incidence pattern where higher-income suburbanites who work in taxing cities pay non-resident rates (typically 0.5-1.2%) while resident workers and lower-income city dwellers bear the full resident rate. The geography matters: a Royal Oak resident commuting to a Detroit office pays only Detroit's 1.2% non-resident rate on Detroit-earned wages (and $0 on any income earned outside Detroit), while a Detroit resident with the same job pays 2.4% on all compensation regardless of where the work happens.

Michigan has a flat 4.25% income tax rate for 2026, unchanged from 2025. State Treasurer Rachael Eubanks formally announced on April 15, 2026 that the conditions for a rate reduction were not met — general fund revenue decreased by 1.56% during fiscal year 2025 while inflation increased by 2.70%, so the statutory reduction formula in Section 51 of the Michigan Income Tax Act did not trigger. Michigan's flat tax has been at 4.25% since 2012 (briefly dropping to 4.05% for 2023 as a temporary, formula-driven reduction that the Michigan Supreme Court later ruled was one-time).
The Lowering MI Costs Plan (Public Act 4 of 2023, signed March 7, 2023, effective February 13, 2024) phases out Michigan's tax on retirement and pension income over four years: 2023 = 25% exemption, 2024 = 50%, 2025 = 75%, and 2026 = 100% full exemption. For tax year 2026, qualifying retirement income for taxpayers born after 1945 is fully exempt from Michigan state income tax. This essentially restores the pre-2012 retirement subtraction. The 2026 maximum private + public benefit subtraction is approximately $65,987 for single filers and $131,794 for married filers. Social Security has been fully exempt at the state level throughout this period.
On $75,000 of Michigan taxable income (single filer) with one personal exemption of $5,800 in 2026, the state income tax is approximately $2,941. Calculation: $75,000 − $5,800 personal exemption = $69,200 Michigan taxable income × 4.25% = $2,941. Your effective Michigan state rate at $75,000 is about 3.92%. If you live or work in a Michigan city with local income tax (such as Detroit at 2.4%, Grand Rapids at 1.5%, or one of 20 smaller cities at 1%), additional local tax applies on top of the state rate. Many major MI cities (Ann Arbor, Troy, Dearborn) have no local income tax.
24 Michigan cities levy local income tax under the Uniform City Income Tax Ordinance (Act 284 of 1964). They divide into three rate tiers: Detroit at 2.4% resident / 1.2% non-resident (highest); Grand Rapids and Saginaw at 1.5% / 0.75%; and 20 other cities at 1% / 0.5% — including Lansing, Flint, Pontiac, Highland Park, Hudson, Albion, Battle Creek, Big Rapids, East Lansing, Hamtramck, Ionia, Jackson, Lapeer, Muskegon, Muskegon Heights, Port Huron, Portland, Springfield, and Walker. Major cities WITHOUT local income tax: Ann Arbor, Troy, Dearborn, Sterling Heights, Warren, Livonia, Novi, Royal Oak, and most suburbs. Non-residents who work in a taxing city pay the non-resident rate on income earned within city limits.
Michigan does NOT tax Social Security benefits — Social Security is fully exempt at the state level. For 2026, all other qualifying retirement income (pensions, 401(k) withdrawals, IRA distributions) is also fully exempt for taxpayers born after 1945 under the Lowering MI Costs Plan, which completes its four-year phase-in (25% in 2023 → 50% in 2024 → 75% in 2025 → 100% in 2026). Additionally, Public Act 24 of 2025 allows taxpayers born after 1952 and age 67+ to claim BOTH the standard deduction AND the Social Security deduction for tax years 2026-2028, removing the previous either/or restriction. Military retirement is also fully exempt regardless of age or tier.
Detroit's city income tax rate is 2.4% for residents and 1.2% for non-residents who work in Detroit, the highest local rate of any Michigan city. The 2:1 resident-to-non-resident ratio is required by Act 284 of 1964. Detroit residents pay the 2.4% on all compensation regardless of where the work is performed; non-residents pay 1.2% only on income earned within Detroit city limits. Highland Park (a separate city completely surrounded by Detroit) levies its own 1% / 0.5% tax. Together, a Detroit resident pays 4.25% (state) + 2.4% (city) = 6.65% combined on top of federal tax — comparable to Columbus, Ohio at 7.297% combined, but lower than New York City at up to 14.8%.
Michigan's 2026 personal exemption is $5,800 per qualifying exemption. You can claim one personal exemption for yourself, one for your spouse (if married filing jointly), and one for each dependent. Michigan also offers special exemptions of $3,400 for individuals who are blind, deaf, paraplegic, hemiplegic, or quadriplegic, and similar amounts for other qualifying conditions. A married couple with two children would claim four personal exemptions = $23,200 of taxable income exempted before the 4.25% rate is applied. Unlike federal personal exemptions (which were eliminated by the 2017 Tax Cuts and Jobs Act), Michigan continues to allow this exemption.
Michigan partially decoupled from federal tax law changes after December 31, 2024 in the 2025-2026 state budget (Public Act 24 of 2025, signed October 7, 2025). Michigan did adopt deductions for qualified overtime wages and qualified tip income (available 2025-2029) — matching some of the federal One Big Beautiful Bill Act (OBBBA) provisions. However, Michigan did NOT adopt the federal senior $6,000 deduction or auto loan interest deduction. The deductions that ARE available on Michigan returns are reflected on MI-1040 Schedule 1. This is more conformity than North Carolina (which adopted none of the OBBBA provisions) but less than full federal conformity.
Yes, Michigan is a flat tax state — every dollar of Michigan taxable income is taxed at the same 4.25% rate regardless of total income or filing status. Michigan adopted its flat tax structure decades ago. The rate has been 4.25% since 2012 (down from 4.35% in 2011), with a temporary one-time reduction to 4.05% for tax year 2023 due to a statutory revenue-trigger formula. The 4.05% reduction was held by the Michigan Supreme Court to be a one-time event, restoring the 4.25% baseline. The 2026 rate determination on April 15, 2026 confirmed 4.25% for another year because the formula did not trigger again. Michigan Republicans have proposed legislation to permanently lower the rate; Democrats have generally opposed.
Michigan's effective property tax rate averages approximately 1.36%, ranking 12th-15th nationally depending on the source. Rates vary substantially by county and millage authority — Wayne County (Detroit), Oakland County (Troy/Royal Oak), and Macomb County (Warren) have varying rates. Michigan's Principal Residence Exemption (PRE) removes school operating millages (typically 18 mills = 1.8%) from your primary residence tax bill if you file the affidavit with your local assessor — this is one of the most valuable Michigan-specific tax benefits and is NOT automatic when you buy a home. Michigan also offers a Homestead Property Tax Credit with a maximum taxable value of $165,400 for 2026.
Michigan's state sales tax rate is 6.0%, with NO local sales tax — Michigan is one of relatively few states where the state rate is the only sales tax rate statewide. This contrasts with Ohio (5.75% state + up to 2.25% local) or Pennsylvania (6% state + 2% local in Philadelphia). Groceries and prescription drugs are exempt from Michigan sales tax. The 6% rate is split: 4% goes to the general fund, 2% is dedicated to the School Aid Fund. Michigan's flat 6% sales tax structure makes total tax burden math relatively easier than states with layered local sales taxes.
Michigan has reciprocal income tax agreements with five neighboring states: Illinois, Indiana, Kentucky, Minnesota, Ohio, and Wisconsin. If you live in Michigan and work in any of these states (or vice versa), you only pay state income tax to your home state — your work state does not withhold. However, reciprocity does NOT apply to Michigan city income taxes. If you commute from Indiana to a job in Detroit, you still owe Detroit's 1.2% non-resident city tax on Detroit-earned wages even though state-level reciprocity exempts you from Michigan state income tax. Verify with payroll to ensure correct withholding.
