Michigan Business Tax Requirements for LLCs

Filing fee: $50

Processing time: 10–15 business days (standard)

State agency: Michigan Department of Licensing and Regulatory Affairs (LARA)

Annual report due: February 15 each year

State tax rate: 4.25% flat individual income tax rate; 6% statewide sales tax

Michigan LLCs don't pay income tax at the entity level. Instead, profits pass through to members, who report them on personal returns and pay Michigan's 4.25% flat income tax rate, federal income tax, and self-employment tax. LLCs that sell taxable goods also collect and remit Michigan's 6% sales tax.

The full picture includes several layers: federal pass-through taxes, Michigan state income tax, sales tax if applicable, estimated quarterly payments, and payroll taxes if you have employees. Each layer has its own forms, deadlines, and thresholds — and missing one can mean back taxes and penalties.

• No entity-level federal income tax — profits pass through to members
• Michigan flat income tax rate: 4.25% on net profits
• Michigan statewide sales tax rate: 6% on taxable goods and certain services
• Self-employment tax applies to active members: 15.3% on net earnings up to the annual threshold
• Estimated quarterly payments required for most LLC members
• Payroll taxes apply if the LLC has employees

How your LLC is taxed at the federal level

By default, a single-member LLC is treated as a disregarded entity for federal tax purposes, meaning the IRS ignores the LLC and taxes the owner directly. A multi-member LLC is treated as a partnership by default and files Form 1065, issuing a Schedule K-1 to each member showing their share of income.

Either way, the LLC itself doesn't pay federal income tax. Members report their share of profits on Form 1040 and pay tax at their individual rate. If your LLC earns enough that the self-employment tax burden becomes significant, it may be worth talking to a tax professional about electing S Corporation status using Form 2553 — that election can reduce self-employment tax on a portion of your income.

Michigan state income tax

Michigan taxes individual income at a flat 4.25% rate. As an LLC member, you report your share of the business's net profits on your Michigan individual income tax return and pay at that rate. There's no graduated bracket system — the same rate applies regardless of how much you earn.

Michigan also allows certain deductions and personal exemptions that can reduce your taxable income. A tax professional can help you figure out which deductions apply to your situation, especially if you have business expenses, home office costs, or depreciation to account for.

Michigan sales tax

Michigan has a 6% statewide sales tax rate. If your LLC sells tangible personal property or certain taxable services, you're required to register for a Michigan Sales Tax License with the Michigan Department of Treasury, collect sales tax from customers at the point of sale, and remit it on a regular schedule — typically monthly, based on your sales volume.

Michigan does not allow local sales tax add-ons, so the 6% rate is uniform across the state. If your LLC buys goods for resale, you'll need a resale certificate to purchase those goods tax-exempt. Register through the Michigan Department of Treasury at michigan.gov/taxes.

Michigan Business Tax and franchise tax

Michigan replaced its old Single Business Tax with the Michigan Business Tax (MBT) in 2008. Most standard LLCs are not subject to the MBT — it primarily applies to businesses with Michigan gross receipts over $350,000 or those that elected to be taxed under the MBT framework. The Corporate Income Tax (CIT) applies to C Corporations, not to pass-through LLCs.

If you're unsure whether your LLC's structure or revenue triggers MBT obligations, a tax professional can help you figure out your exposure. Most single-member and multi-member LLCs taxed as partnerships won't owe MBT.

Self-employment tax

If you're an active member of your LLC — meaning you work in the business, not just a passive investor — you owe self-employment tax on your net earnings. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. This covers both the employee and employer portions since you're paying both sides as a self-employed person.

Self-employment tax is one of the bigger surprises for first-time LLC owners. You can deduct half of your self-employment tax when calculating your adjusted gross income on Form 1040, which softens the impact somewhat.

Estimated quarterly tax payments

Most LLC members need to make estimated tax payments four times a year — to both the IRS and the Michigan Department of Treasury. Because no employer withholds taxes from your LLC income, you're responsible for paying as you go. Missing or underpaying estimated taxes can result in a penalty when you file your annual return.

Federal estimated payments are due in April, June, September, and January. Michigan follows a similar schedule. A tax professional can help you figure out the right payment amounts based on your projected income for the year.

Payroll and employer taxes

If your LLC has employees, you take on a separate set of tax obligations. You'll need to withhold federal and Michigan state income tax from employee wages, pay the employer's share of Social Security and Medicare (FICA), and pay federal unemployment tax (FUTA) and Michigan unemployment insurance (UI) contributions.

Payroll tax requirements are detailed and time-sensitive. Getting them wrong can mean you're on the hook for back taxes, penalties, and interest. An accountant or payroll service can help you stay on track from the first paycheck.
