If your business operates in Michigan—or sells to Michigan customers—you’ll need to secure a Michigan sales tax permit before collecting a single dollar in tax. Whether you’re opening a storefront, launching an e-commerce brand, or selling at pop-up events, this permit is the legal foundation for compliance. But between economic nexus rules, taxability quirks, and registration through the Michigan Treasury Online (MTO) system, the process can feel overwhelming.
That’s why we created this step-by-step guide—to help you register correctly and avoid costly mistakes. And if you’d rather skip the hassle entirely, Hands Off Sales Tax (HOST) can take care of everything for you.
Who Needs a Michigan Sales Tax Permit?
Let’s clarify who needs a Michigan sales tax permit. These are essential for any business that crosses nexus thresholds or has physical ties to the state.
Nexus Explained
- Physical Nexus
Having a storefront, warehouse, office, or even storing items in Amazon FBA within Michigan establishes nexus—triggering a permit requirement. - Economic Nexus
Out-of-state sellers must register if they meet the economic threshold: $100,000 in sales OR 200 transactions during the previous calendar year. - Marketplace Facilitator Rules
Marketplaces like Amazon or Etsy that meet the same economic thresholds must collect and remit taxes on behalf of third-party sellers. If they are collecting for you, you typically don’t need to register separately, unless you still make sales outside those platforms.
Who This Affects
- Local retailers with inventory or storefronts
- Remote sellers selling online or via mail-order
- Pop-up and mobile vendors at fairs, markets, or events
- Amazon FBA users or sellers with other third-party warehousing
- Artists or crafters selling via online marketplaces or at shows
Why This Matters
Every business that meets these nexus definitions must collect sales tax, register via MTO, and file returns. Too often, sellers assume there’s no nexus and avoid registration—only to face unexpected penalties later.
Before You Begin: Essential Info & Prep
Setting up a Michigan sales tax permit starts with having the right information and documents ready. Here’s what to prepare before logging into MTO.
Required Business Information
Make sure you have this checklist completed:
- Federal EIN (or SSN for sole proprietors)
- Legal business structure (LLC, Corporation, Sole Proprietor)
- SSN/EIN of the responsible party (owner/officer)
- NAICS code that matches your business activity
- Business addresses, including storefront or warehouse locations in Michigan
Document Preparation
- Resale certificates (Form 3372) for tax-exempt purchases—keep copies ready to use with vendors.
- MTO login credentials: create your account before registration to avoid delays .
- Event vendor forms (Concessionaire): if you sell at fewer than three events per year, you may use Form 5089 instead of a full permit.
Being fully prepared ensures a smoother experience in the MTO portal—reducing errors and accelerating permit issuance.
Step‑by‑Step Registration Process via MTO
Let’s walk through registering for your Michigan sales tax permit using the Michigan Treasury Online (MTO) portal. With clear visual cues and smart tips, you’ll breeze through the process.
A. Create and Connect Your MTO Account
- First, visit MTO and select “Create My User Profile” to set up your profile.
- After logging in, click “Start a New Business (E‑Registration)” to begin the sales tax permit process.
B. Complete Business Registration
- Choose Sales & Use Tax when selecting tax types, and have ready your EIN, NAICS code, and business details.
- If you anticipate economic nexus through out-of-state activity, register as a Sales and Use License holder.
C. Form 518 & Instant License Access
- For new businesses without an EIN, you’ll complete Form 518 directly in the portal—this replaces the paper application.
- Upon submission, your license becomes available almost immediately within your MTO dashboard, with a physical copy arriving by mail within 7–10 days.
Pro Tips
- Use modern browsers—Chrome, Edge, Firefox—for best compatibility.
- Save the confirmation number for future correspondence.
- Keep your login information safe—you’ll use MTO for ongoing filings, payments, and compliance tasks.
With your permit active in MTO, you’re ready to collect, file, and manage Michigan sales tax with confidence.
After You Submit: What Happens Next
Once you’ve completed your Michigan sales tax permit registration via MTO, here’s what follows:
Immediate MTO Access
Your sales tax license becomes instantly available in your Michigan Treasury Online (MTO) dashboard once the e-registration is processed—a confirmation you can print and use as proof. You don’t need to wait to begin collecting sales tax.
Physical License Arrival
Expect a printed license in the mail within 7–10 business days. Keep it on-site if you have a physical location, as it may be needed during inspections or local compliance checks.
Annual Renewal Cycle
Michigan sales tax licenses are valid January through December each year. The Department automatically renews your permit—there’s no action required unless the state changes the renewal policy.
With access to your license in MTO and a mailed copy arriving soon, you’re fully authorized to collect sales tax. The automatic annual renewal keeps you compliant effortlessly, but mark your calendar in case Michigan updates its licensing approach.
Collection, Filing & Frequency Rules
Once your Michigan sales tax permit is issued, staying compliant means understanding your filing frequency, deadlines, discounts, and reconciliation requirements.
Filing Frequency & Deadlines
Michigan determines your required filing frequency—monthly, quarterly, or annually—based on your total tax liability:
- Monthly: Businesses collecting over ~$1,000/month
- Quarterly: $63–$999/month
- Annual: Under ~$63/month
Returns and payments are due by the 20th of the following month or quarter.
Vendor Discounts
Michigan incentivizes timely filings with a vendor discount on state sales tax:
- 0.75% for payments made by the 12th of the month
- 0.50% for payments between the 13th and 20th
Discounts apply only to the first 4% state tax and are capped at $15,000 per month.
Combined SUW Returns
If you’re registered for Sales, Use, or Withholding taxes, Michigan requires a single combined return using Form 5080 for monthly and quarterly filers. An annual reconciliation is also filed by February 28.
Paying on time, using the vendor discounts, and correctly filing combined returns not only keeps you compliant—it also saves money.
Zero Returns & Account Closure
Even with no sales, your Michigan sales tax permit requires consistent attention. Here’s how to stay compliant and close your account properly when needed.
Zero Returns
- Michigan mandates that all permit holders file a zero sales tax return if no tax is collected during a filing period, regardless of filing frequency.
- Neglecting zero returns can result in penalties or audit red flags, even when no tax is owed.
Closing Your Permit
- When discontinuing your business, fill out Form 163 (Notice of Change or Discontinuance)—available via the Treasury website—and mail it to the Registration Section in Lansing.
- Include your final tax period and ensure all outstanding sales and use taxes are paid.
- Filing Form 163 formally closes your account and stops the requirement for zero returns.
By filing zero returns faithfully and using the correct process to close your permit, you avoid unnecessary penalties and secure a clean exit from Michigan’s tax obligations.
Taxability & Special Scenarios
Getting smart on what’s taxable in Michigan—and what isn’t—can save you money and help avoid mistakes. Here’s what you need to know:
Flat, Origin-Based Tax
Michigan charges a uniform 6% sales tax statewide, with no additional local taxes.
Delivery & Installation Charges
Thanks to Public Acts 20 and 21 (April 2023), most delivery and installation fees are now exempt if:
- They’re separately stated on invoices, and
- The seller maintains documentation for them.
Before April 26, these were taxable, and any past overpayments are being relieved.
Digital Goods & SaaS
- Digital products like e-books, movies, and music are exempt—they’re not considered “prewritten software.”
- SaaS—software accessed online without download—is likewise non-taxable, unless downloadable components are involved.
Shipping & Handling
If delivery isn’t clearly separated or the seller handles shipping themselves, delivery/handling charges may be taxable.
Common Exemptions
Non-taxable categories include:
- Unprepared groceries and prescription medications
- Sales to 501(c)(3) nonprofits, government agencies, and certain medical or educational institutions
Understanding these nuanced rules around digital products, shipping, and exempt sales can significantly reduce tax liability. Stay informed, as compliance isn’t just about filing—it’s about saving smartly too.
Audit Triggers & Recordkeeping
Ensuring your business is audit-ready means understanding what alerts Michigan’s Department of Treasury—and maintaining records that stand up under scrutiny.
Common Audit Triggers
- Late or missing filings, including zero returns—even with no sales, a missing return can prompt an audit.
- Inconsistent tax collection, such as sudden shifts in taxable items or misclassification of goods and services may signal noncompliance.
- Skipping zero returns across periods signals lapses and invites further investigation.
Recordkeeping Requirements
Michigan law mandates maintaining complete records in either digital or physical format for at least four years after the due date or filing date, whichever is later. These records should include:
- Sales logs, cash register tapes, and general ledgers
- Copies of exemption and resale certificates
- Documentation related to concessions, mobile events, or temporary sales
Best Practices
- Organize files by period, type, and tax category
- Retain digital backups—especially for receipts and certificates
- Include any concession or event-specific permits

Frequently Asked Questions (FAQs)
1. Do I need a Michigan sales tax permit to sell online in the state?
Yes, if you have economic nexus (over $100,000 in sales or 200+ transactions annually) or physical presence (inventory, employees, or pop-ups), you must register for a Michigan sales tax permit, even if you’re only selling online.
2. How long does it take to get a Michigan sales tax permit?
If you apply through the Michigan Treasury Online (MTO), the permit is typically issued immediately. A printed copy is mailed within 7–10 business days. You can begin collecting and filing sales tax once the license is active.
3. Is there an annual renewal requirement for Michigan sales tax permits?

4. What if I didn’t make any sales during the filing period?
Even if you have zero sales, you’re still required to file a “zero return” by the due date. Failure to do so may trigger penalties or audit flags, so it’s important to file every period, regardless of activity.
5. Are digital products or SaaS taxable in Michigan?
