Michigan Tax Debt Relief
Treasury penalties, twice-yearly interest resets, and a separate layer of city income tax. What a Michigan balance really costs and the paths to settling it.

Michigan's income tax looks like one flat number. In practice, roughly two dozen cities stack their own income tax on top, and the biggest of them hands its collection straight to the state.
The layer people forget
About two dozen cities tax your income too
Michigan is one of the few states where roughly two dozen cities levy their own local income tax in addition to the 4.25% state tax. Detroit charges 2.4% for residents and 1.2% for nonresidents, Grand Rapids and Saginaw charge 1.5% and 0.75%, and about twenty other cities charge 1% for residents and 0.5% for nonresidents. Someone with tax debt in Michigan may actually owe two separate governments, and city balances are collected separately from the state balance.
Detroit is different: the state collects it
Unlike most Michigan cities that run their own collections, the City of Detroit income tax is administered by the Michigan Department of Treasury. That means a Detroit resident behind on city income tax is dealing with the same state Collection Services Bureau, penalty rules, and enforcement powers that apply to the state income tax. Flint income tax is scheduled to move to state administration starting January 1, 2027 for the 2026 and later tax years.
A flat rate that bounced
Michigan's income tax is a single flat 4.25% rate, but a 2015 trigger law cut it to 4.05% for the 2023 tax year when state revenue outpaced inflation. Michigan courts, upheld through the state Supreme Court, ruled that any such trigger cut is temporary and lasts only one year, so the rate snapped back to 4.25% for 2024 and has stayed there for 2025 and 2026. Taxpayers reconciling old 2023 balances should note the rate for that single year was different.
Interest that resets twice a year
Instead of a fixed statutory rate, Michigan sets interest on unpaid tax at 1 percentage point above the adjusted prime rate charged by large commercial banks, and it re-sets the number every January 1 and July 1. Because it floats, the annual rate has swung from 5.65% in early 2023 up to 9.50% in late 2024 and back down to 8.48% for the first half of 2026. Interest accrues on a daily rate, so a growing balance compounds differently across each six month period.

Resolving a Michigan balance
- Installment Agreement (payment plan)
- Treasury lets individuals pay a balance over time in monthly installments. It will typically grant up to a 24 month plan without requiring detailed financial information, and individual taxpayers may be allowed up to 48 months. Penalties and interest keep accruing while the plan is active, and Treasury may still file a lien to protect the state's interest. Requests go through the Collection Services Bureau.
- Offer in Compromise
- Established by Public Act 240 of 2014, Michigan's Offer in Compromise program lets a taxpayer ask Treasury to settle an assessed liability, including tax, penalty, and interest, for less than the full amount. A taxpayer generally must qualify on one of three grounds: they received a federal IRS Offer in Compromise on the same tax, there is doubt as to liability, or there is doubt as to collectibility because they cannot reasonably pay the full debt within a reasonable time. Acceptance is not guaranteed and Treasury reviews finances closely.
- Penalty waiver (reasonable cause)
- Treasury may waive penalties, but not the underlying tax or interest, if the taxpayer shows reasonable cause for filing or paying late. Accepted reasons include serious illness or death of the person responsible for filing, fire, theft, or other extenuating events, or a Department error in applying payments. Treasury states that lack of funds or poor recordkeeping is not reasonable cause. The request must be in writing to the Collection Services Bureau.
- Hardship and uncollectible status
- When a taxpayer genuinely cannot pay, Treasury's Collection Services Bureau can evaluate financial hardship. This is not a formal forgiveness program, but Treasury may hold enforced collection, adjust a payment plan, or consider an Offer in Compromise on doubt as to collectibility grounds based on documented income, expenses, and assets.
Michigan tax debt questions
What is the penalty for paying Michigan income tax late?
Michigan charges a late penalty of 5% of the unpaid tax for the first 2 months, then an additional 5% for each following month the tax stays unpaid, up to a maximum of 25% of the tax owed. Daily interest is charged on top of that penalty and is separate from it.
How is Michigan's interest rate on unpaid tax set?
Under MCL 205.23(2), the rate is 1 percentage point above the adjusted prime rate charged by large commercial banks, and Treasury re-sets it every January 1 and July 1. For the first half of 2026 the adjusted annual rate is 8.48%, applied through a daily factor. It has ranged from 5.65% in early 2023 to 9.50% in late 2024.
Can I set up a payment plan for Michigan back taxes?
Yes. Treasury offers installment agreements through its Collection Services Bureau, typically up to 24 months without detailed financial disclosure and up to 48 months for individual taxpayers. Penalties and interest continue to accrue while you pay, and Treasury may still file a lien.
Does Michigan have an Offer in Compromise program?
Yes. Under Public Act 240 of 2014, Michigan can settle an assessed tax debt for less than the full amount if you received a federal IRS Offer in Compromise on the same tax, there is doubt as to liability, or there is doubt as to collectibility. Acceptance is not guaranteed and Treasury reviews your finances.
Do I owe city income tax too if I live in Michigan?
You might. About two dozen Michigan cities, including Detroit, Grand Rapids, Flint, and Saginaw, levy their own income tax in addition to the state's 4.25%. Detroit's tax is collected by the state Treasury, while most other cities handle their own filing and collections, so a city balance is separate from your state balance.
How long can Michigan collect a tax debt?
MCL 205.27a generally gives Treasury at least 6 years to collect an assessed debt. That period can be extended by a court judgment, an approved payment agreement, a pending appeal, or bankruptcy, so a specific debt can stay collectible longer than 6 years.
