Getting a Missouri sales tax permit is a legal requirement for anyone selling taxable goods or services in the state—whether you run a brick-and-mortar shop, sell online, or operate as a seasonal vendor. But the process isn’t always intuitive. From choosing the right type of license to calculating your bond and filing the right forms, each step matters.
This guide breaks it all down with clear, accurate steps to help you register and stay compliant. And if you’d prefer to offload the paperwork entirely, Hands Off Sales Tax (HOST) can take care of it for you—start to finish.
What Is the Missouri Sales Tax Permit?
Here’s a clear breakdown to help you understand the different licenses involved in Missouri.
A Retail Sales Tax License is for in-state sellers making taxable retail sales of goods or services within Missouri. An out-of-state seller making sales from outside Missouri to Missouri customers needs a Vendor’s Use Tax License, which authorizes them to collect Missouri sales tax on those remote transactions.
Both licenses are registered via Form 2643 (Missouri Tax Registration Application). This form covers retail sales tax, vendor’s use tax, consumer’s use tax, and other tax types. Physical and seasonal sellers also indicate their taxable start dates and business operation months on this form.
Who Needs to Register? Nexus & Seller Types
Understanding who must register for a Missouri sales tax permit depends on your business’s connection—or nexus—to the state and the type of seller you are.
Physical Nexus
You need a Retail Sales Tax License if any of the following apply:
- You operate a brick-and-mortar store, warehouse, or hold inventory in Missouri
- You have employees or contractors working in the state
- You conduct business through Amazon FBA or other in-state fulfillment centers
Economic Nexus
Under Missouri’s Wayfair law (effective January 1, 2023), remote sellers must register for a Vendor’s Use Tax License if, in the current or prior 12-month period, they exceed $100,000 in gross sales into Missouri. Missouri does not impose a transaction-count threshold, only the dollar volume criterion. Once triggered, sellers must begin collecting state and local tax no later than three months after the quarter-end.
Transient Sellers & Fair Vendors
Under RSMo § 144.118, sellers at fairs, craft shows, or pop-ups must obtain a Retail Sales Tax License and collect tax on-site—even temporarily. Operating without a license may result in early penalties (up to $500 on day one, then $100 daily, capped at $10,000).
By identifying your nexus type and vendor status, you can determine precisely which license you need and ensure compliance—whether you’re a local retailer, online seller, or event-based vendor.
Bond Requirements & Refund Process
Here’s a breakdown of Missouri’s sales tax bond rules—what you owe upfront and how/when you can reclaim it.
Bond Amount & Calculation
New Missouri taxpayers applying for a Retail Sales Tax License or Vendor’s Use Tax License must post a bond or equivalent collateral worth three times their average monthly tax liability, based on either the previous owner’s records or estimated liability.
For example, if average monthly liability is $700, the required bond is $2,100. Minimum bond amounts apply: $25 if three times liability is under $500; otherwise, the bond must be rounded to the nearest $10.
Acceptable Bond Forms
You can post your bond via:
- Cash bond (cashier’s check, money order, certified check, or credit card)
- Surety bond from an insurance company licensed in Missouri
- Certificate of Deposit (CD) made out jointly to Missouri DOR and your business
- Irrevocable Letter of Credit meeting state requirements
The bond must remain in force unless replaced; if canceled, a new bond must be submitted within 30 days, or your license is nullified.
Refund & Release Eligibility
After at least two years of satisfactory compliance—meaning no late filings or outstanding tax due—or once you close your sales/use tax account and file a final return, you may request a bond refund. Refunds are issued after the Department confirms there are no delinquencies.
Understanding Missouri’s bond regulations upfront saves time and money—especially when you know how and when you can recover your collateral.
Step‑by‑Step Registration Process
To get started, here’s exactly what you need and how to complete your Missouri sales tax registration—from checklist to submission.
Pre‑Application Checklist
Before you begin, gather these essentials—many outlined on Form 2643’s first pages:
- Federal EIN (for businesses with employees or withholding obligations)
- NAICS code matching your business activity
- Ownership information: Names, SSNs, birthdates, and addresses for owners/officers/partners
- Business structure details (LLC, corporation, sole prop) and charter numbers
- Estimated monthly sales to determine filing frequency and bond requirements
- Previous business owner’s info (if applicable, for transfers)
- Power of Attorney (Form 2827) to delegate filing authority, if needed
Online Registration via MyTaxMissouri
- Visit MyTaxMissouri and select “Register New Business.”
- Complete the online version of Form 2643, selecting the correct license types (Retail or Vendor’s Use).

- The Tax ID and PIN allow you to file sales tax returns using Form 53-1 in MyTaxMissouri.
Mail-In Registration

Mail the form to:
Missouri Department of Revenue

Completing this registration workflow accurately ensures you’ll receive your Tax ID, be ready to file returns, and start collecting sales tax without delays.
Filing Frequency, Zero‑Returns & Penalties
Here’s what Missouri requires for filing rhythms, zero-returns, and handling late submissions:
Filing Frequency
Missouri sets your filing schedule—monthly, quarterly, or annually—based on state tax collected, not local taxes:
- Monthly: If state taxes exceed $500/month, file monthly returns (Form 53–1) due by the 20th of the following month (or last day if it ends the quarter).
- Quarterly: If state taxes are $45–$500/month, file quarterly—due on the last day of the month after quarter-end.
- Annually: If state taxes are below $45/quarter, file annual returns by January 31 of the next year.
Quarter-Monthly Payments:
Businesses exceeding $15,000/month in state tax may need quarter-monthly payments, due within three banking days after each seven-day sub-period.
Zero-Return Requirement
Missouri mandates filing even with zero tax due. Not filing may lead to penalties or license revocation.
Due Dates & Penalties
- Returns are due on the 20th of the following month or last day after quarter-end—weekend/holiday extensions apply.
- Late filing: Penalty is 5% per month, up to 25% max, plus interest on overdue amounts.
By staying on top of your filing frequency and zero-return obligations, you can avoid high penalties and keep your Missouri license in good standing.
Exemption & Resale Certificate Process
Here’s how Missouri retailers and wholesalers comply when selling tax-exempt items or making purchases for resale.
Missouri Form 149 Exemption Certificate
Missouri uses Form 149 (Sales and Use Tax Exemption Certificate) to document exempt purchases for resale or other qualifying exempt purposes. Buyers must complete and provide this form to sellers prior to the sale.
When to Use Form 149
- Resale of tangible goods: Applicable when purchasing items for resale in the ordinary course of business.
- Resale of taxable services: Available if the purchaser has a Missouri retail license, covering services like rentals, amusement, or telecoms.
- Manufacturer/wholesaler purchases: Available even without a Missouri ID, but limited to non-retail transactions.
Seller’s Responsibilities
- Accept only fully completed and accurate Form 149 certificates.
- Retain certificates in your files throughout the audit retention period—typically three years.
- Use blanket certificates for frequent buyers, but ensure they are renewed every five years (such as for tire-related exemptions).
Maintaining proper documentation and exercising reasonable care in accepting certificates shields your business during audits. Inconsistent or flawed records could result in liability for unpaid sales tax, penalties, and interest.

Frequently Asked Questions
1. Do I need a Missouri sales tax permit if I only sell online?
Yes. If you have physical nexus (like inventory stored in Missouri or contractors in-state), you need a Retail Sales Tax License. If you’re a remote seller exceeding $100,000 in annual Missouri sales, you must register for a Vendor’s Use Tax License under Missouri’s economic nexus law.
2. How long does it take to get a Missouri sales tax permit?
Online applications through MyTaxMissouri are typically processed in 2 business days. Paper applications may take 7–10 business days after receipt by the Missouri Department of Revenue.
3. Is there a fee to apply for a sales tax permit in Missouri?
There is no direct fee to obtain the permit. However, most applicants must submit a bond equal to 3× their average monthly tax liability. This serves as a compliance security deposit.
4. Can I sell at fairs or pop-up events without a Missouri sales tax permit?
No. Transient vendors must obtain a Retail Sales Tax License, even for one-day events. Operating without one can result in fines of up to $10,000.
5. Do I have to file returns if I made no sales?
Yes. Missouri requires zero-returns even if no tax is due. Failing to file may result in penalties or the cancellation of your license.
