Michigan Tax Payment Plan Calculator

How Michigan Tax Payment Plans Work

In Michigan, the Michigan Department of Treasury lets taxpayers who have already received a Notice of Intent to Assess or a Final Bill for Taxes Due request an installment agreement, generally by filing Form 990; terms run up to 24 months without extra paperwork, longer terms require a Collection Information Statement, and interest currently runs at 7.85% a year (adjusted every January and July) on the unpaid balance. Treasury's published guidance does not list a flat setup fee. Because interest and late-payment penalties keep accruing throughout the plan, the largest payment amount you can sustain is usually the cheapest path — the calculator above shows that trade-off for your exact balance.

What's Specific to Michigan

Is a Payment Plan Your Best Option?

A Michigan installment agreement isn't always the cheapest path. Here's how it compares to the other ways to resolve a tax bill in Michigan:

‍

Before You Apply Online

Consider getting tax help before applying on your own if:

• You can't sustain a monthly payment that clears the balance within 24 months.
• You expect to need longer than 24 months and haven't prepared a Collection Information Statement.
• You have missing or unfiled Michigan tax returns.
• You already defaulted on a prior Michigan installment agreement.
• You've received a levy, garnishment, or lien notice.
• You owe both Michigan state tax and federal tax balances.
• Your business collected sales, use, or withholding tax.
• Your income is unstable or has recently reduced.

Applying online with the wrong setup can lock you into an unaffordable payment amount or cause you to miss a more cost-effective tax resolution option.

Common Mistakes With Michigan Payment Plans

• Proposing a monthly payment too low to clear the balance within 24 months
• Forgetting that interest keeps accruing at the adjusted prime rate plus 1%, even though penalties cap at 25%
• Falling out of compliance — a new unfiled or unpaid return that can trigger default
• Missing a single payment and losing the installment arrangement with little warning
• Requesting a plan before filing missing Michigan returns — Treasury generally won't maintain a plan with unfiled returns
• Setting up a Michigan installment agreement without coordinating a separate IRS agreement if you also owe federal tax
• Assuming an installment agreement automatically removes an existing state tax lien, levy, or garnishment
• Not asking about a penalty waiver before locking into a long-term payment plan

How to Apply in Michigan

Apply online through Collections eService, by phone at 517-636-5265 for individuals or 517-827-3227 for businesses, or by mailing a completed Form 990 to the Michigan Department of Treasury, Collection Services Bureau, P.O. Box 30199, Lansing, MI 48909. The calculator is an estimate to help you pick a payment amount before you apply; Treasury sets official terms and may require a Collection Information Statement for agreements longer than 24 months.

Does Michigan offer a tax payment plan?

Yes, the Michigan Department of Treasury offers an installment agreement that lets individuals and businesses pay state tax debt over time. You generally apply after receiving a Notice of Intent to Assess or a Final Bill for Taxes Due, using Form 990, the Collections eService portal, or by calling the Collection Services Bureau. Treasury sets the payment amount and term based on your account balance and ability to pay.

In Michigan, how long can a payment plan last?

Most Michigan installment agreements run up to 24 months and only require Form 990 with your proposed payment schedule. Agreements longer than 48 months are possible but require a Collection Information Statement showing your income, expenses, and assets. Treasury reviews your financial situation and may shorten the term, require a larger payment, or ask for additional documentation before approving a longer repayment period.

Does Michigan keep charging interest during a payment plan?

Yes, the Treasury charges interest on unpaid Michigan tax balances at one percentage point above the adjusted prime rate, currently 7.85% annually through December 2026, and the rate adjusts every January and July. Late-payment penalties also continue, starting at 5% for the first two months and adding 5% monthly after that, up to a 25% cap. Paying more than the minimum reduces the total interest owed.

What's the minimum monthly payment in Michigan?

Michigan does not publish a fixed minimum dollar amount. When you file Form 990, you propose a monthly or bi-weekly payment amount, and Treasury either approves it, adjusts it, or requests a Collection Information Statement if the term exceeds 48 months. Your proposed amount should realistically pay off the balance within the agreed term, since an unrealistically low offer risks rejection or default.

What happens if I miss a payment in Michigan?

Missing a payment can put your installment agreement in default. Michigan's Treasury guidance warns that permission to pay in installments may be withdrawn and the full remaining balance collected through wage levy, bank levy, or asset seizure, sometimes without additional advance notice. Contact the Collection Services Bureau immediately if you expect to miss a payment, since early communication can sometimes prevent default and further enforcement action.

Will Michigan still file a lien if I'm on a payment plan?

Yes, a lien is possible. A Michigan tax lien can attach automatically once a liability goes unpaid, and the Treasury generally will not release an existing lien just because you enter an installment agreement; liens usually remain until the balance is paid in full. The lien can last seven years and be refiled for another seven, and it may affect your credit and ability to sell or refinance property.

Is a payment plan my best option?

No, it's not always your best option. An installment agreement makes sense if you can afford steady payments and want to stop collection escalation, but interest and penalties keep accruing the entire time. If your balance is unaffordable long-term, an offer in compromise, penalty, and interest waiver request, or currently-not-collectible status may cost less overall. Compare options, and coordinate separately with the IRS if you owe federal tax, too.

Do I need to file my returns before a payment plan in Michigan?

Generally, yes, you do. Treasury typically will not set up or maintain an installment agreement if you have missing or unfiled Michigan returns, since an unfiled return means your true balance isn't known. Before requesting a plan, file any outstanding returns for prior years. Filing first helps avoid delays, protects you from additional failure-to-file penalties, and improves your chances of Treasury approving a workable payment schedule.
