How to Register for a Sales Tax Permit in Michigan: A Step-by-Step Guide for New Businesses

If your business sells taxable goods in Michigan, you need the right state tax registration before you start collecting sales tax. The Michigan Department of Treasury issues a sales tax license, often called a sales tax permit, so businesses can collect and remit the 6% Michigan sales tax on taxable retail sales.

Michigan registration is straightforward, but it is easy to miss details that matter: which businesses need to register, when to apply, what information Treasury asks for, and how filing works after you receive your license. This guide walks through the process step by step and explains the compliance rules that follow.

What a Michigan Sales Tax Permit Does

A sales tax permit authorizes your business to collect Michigan sales tax from customers on taxable sales. It does not create the tax obligation by itself. If your business is already required to collect sales tax, the permit simply allows you to do so legally and report the tax correctly.

Michigan generally applies a 6% sales tax to taxable retail sales. The state does not allow local cities or counties to add their own sales tax. Certain items, such as residential electricity, natural gas, and home heating fuel, are taxed at 4%.

Who Needs to Register

In general, you need a sales tax license if you sell tangible personal property to the final consumer in Michigan. That includes most retail businesses and many businesses that make taxable sales of products.

You may also need to register if you are an out-of-state seller with Michigan nexus. Under Michigan's economic nexus rules, a business can have a filing obligation if, in the previous calendar year, it had more than $100,000 in sales into Michigan or more than 200 transactions with Michigan customers. These thresholds include taxable, nontaxable, and exempt sales when determining whether nexus exists.

You should also pay attention to these situations:

• Retailers selling at events more than two times per year in Michigan generally need a sales tax license.
• Businesses that sell taxable goods along with services may need a license if the customer receives tangible property as part of the transaction.
• Contractors and subcontractors are generally not required to hold a sales tax license for materials they affix to real property, because they are treated as the final consumer of those materials.
• Marketplace sellers should review whether their sales are reported by the marketplace facilitator or by their own business.

When to Apply

Apply before you begin making taxable retail sales. Michigan Treasury says you do not have to wait for the physical license to arrive before you start selling, but you must begin remitting tax as soon as taxable sales start.

If you are buying an existing business or acquiring a business with taxable sales, include the registration in your closing and onboarding process. The state’s online registration process is available for new businesses and for employers acquiring or purchasing a business.

What Information You Need

Before you register, gather the key business details Treasury will ask for:

• Legal business name
• Business address
• Federal Employer Identification Number
• Contact information for the business owner or responsible party
• NAICS code
• Date business began or will begin operations in Michigan

Having this information ready makes the application smoother and reduces the chance of delays.

How to Register for a Sales Tax License in Michigan

Michigan offers online registration through Michigan Treasury Online, which is the fastest option. You can also mail Form 518, Registration for Michigan Taxes.

Option 1: Register Online Through MTO

The online process is the most efficient route for most businesses.

1. Create or access your Michigan Treasury Online account.
2. Start the business registration application.
3. Enter your business identity, address, ownership, and tax details.
4. Select sales tax registration when prompted.
5. Review the application carefully before submitting.
6. Save your confirmation number.

Michigan Treasury says the online e-registration process is much faster than registering by mail, and a new sales tax license can be available in as little as 7 business days.

Option 2: Register by Mail

If you prefer paper filing, you can submit Form 518 by mail. This option takes longer, and Treasury notes that mailed applications can take several weeks to process.

Option 3: Special Cases

If you are a marketplace seller, a concessionaire, or a business with unusual filing circumstances, review Treasury guidance before choosing a registration path. The right setup depends on how and where you make sales.

After You Register

Once Treasury processes your registration, your sales tax license is available in Michigan Treasury Online with registration access. You can also print a copy from your MTO account.

Your sales tax license is issued yearly and is valid from January 1 through December 31 of the tax year listed on the license. Keep that in mind when planning year-end compliance.

Filing and Remitting Sales Tax

After registration, your business must file returns and remit tax on the schedule Treasury assigns. Filing frequencies are monthly, quarterly, or annual, based on your expected activity and, after the first tax year, your actual tax liability.

Important filing rules:

• File even if no tax is due.
• Monthly returns are generally due on the 20th of the following month.
• Quarterly returns are generally due on the 20th of the month after the quarter ends.
• Annual returns are due by February 28 of the following year.
• If a due date falls on a weekend or state holiday, the deadline moves to the next business day.

Michigan also requires all filers to submit an annual return by February 28, regardless of their assigned filing frequency.

Common Mistakes to Avoid

A few simple errors can create unnecessary penalties or compliance headaches.

1. Waiting too long to register

If your sales are taxable, registration should happen before or immediately after your first sale. Delaying registration can put your business behind on remittance obligations.

2. Assuming all services are exempt

Some services are taxable when they involve property that goes with the customer or when the business sells tangible items alongside services. Review the transaction carefully instead of assuming service income is always exempt.

3. Missing your filing frequency

Treasury assigns a filing schedule, and you must follow it. Annual filing does not replace monthly or quarterly returns.

4. Ignoring economic nexus

Out-of-state businesses often assume they do not need to register because they have no physical office in Michigan. That is not always true. Sales volume and transaction counts can create a filing obligation even without a physical presence.

5. Losing track of exemptions and resale certificates

If you make exempt sales, keep the supporting documentation. Proper records help you justify why tax was not collected on a transaction.

How to Stay Compliant After Registration

Registration is the start, not the finish. Ongoing compliance requires a process.

Use these habits to stay current:

• Reconcile sales tax collected against sales tax due each filing period.
• Separate taxable and exempt sales in your accounting system.
• Track marketplace sales, direct sales, and event sales separately.
• Keep exemption certificates and resale records organized.
• Set calendar reminders for filing deadlines.
• Review your sales activity each year to confirm your filing frequency is still accurate.

If your business sells in multiple states, use a centralized compliance workflow so Michigan returns do not get lost in a larger multi-state tax process.
