What is the penalty for paying sales tax late in Missouri?

Missouri imposes a 5% penalty on unpaid sales tax if you miss the filing deadline. This applies immediately, even if you’re only a day late. Interest also starts accruing from the original due date at a rate the state sets annually, typically in the 4-5% range.

The 5% penalty is calculated on the tax you owe, not your total sales. If you collected $1,500 in sales tax last month and file a week late, you’re looking at a $75 penalty plus whatever interest has accumulated. That might not sound devastating, but it adds up quickly if you’re late multiple periods or if the amount is larger.

Filing late and paying late are treated as separate problems. If you file your return on time but can’t pay, you still face the penalty and interest on the unpaid amount. If you don’t file at all, the Department of Revenue may estimate what you owe and assess additional penalties on top of what you already owe. Filing something is always better than filing nothing.

Extended delinquency creates bigger headaches. The state can place liens on your business assets, revoke your sales tax license, or pursue aggressive collection actions. At that point you’re not just paying penalties. You’re dealing with enforcement that disrupts your ability to operate normally. Sales tax filing deadlines vary based on your collection volume, so knowing your schedule matters.

If you’re already behind, file the return as soon as possible to stop additional penalties from piling up. Contact the Missouri Department of Revenue about a payment plan if you need one. They’d rather work with a business owner showing good faith than chase someone who went silent. Communicating early gives you more options than waiting for them to come to you.

The cleanest path is staying current in the first place. Track what you collect, know when your returns are due, and treat sales tax as money you’re holding for the state rather than operating cash. A Mid-Missouri bookkeeper can build this into your monthly routine so deadlines don’t sneak up on you and small oversights don’t turn into expensive problems.
