Tax-Exempt Items and Special Rules in Missouri
Missouri taxes groceries at a reduced state rate of 1.225% instead of the full 4.225%. However, local taxes may apply at their full rates to grocery purchases, so the total tax on food varies by location and can be significant in high-local-tax areas. Prescription drugs are fully exempt.
| Category | State Rate | Notes |
|---|---|---|
| Groceries | 1.225% (reduced) | Local taxes may apply at full rate |
| General merchandise | 4.225% | Standard rate plus local |
| Clothing | 4.225% | No clothing exemption |
| Prescription drugs | Exempt | All prescription medications |
| Over-the-counter medicine | 4.225% | Taxed at full rate |
| Farm equipment | Exempt | Equipment used directly in farming |
| Manufacturing machinery | Exempt | Equipment for manufacturing operations |
| Motor vehicles | 4.225% | State rate only; no local tax on vehicles |
Missouri holds a back-to-school sales tax holiday (typically the first full weekend in August) during which clothing items up to $100, school supplies up to $50, computer software up to $350, and personal computers/accessories up to $1,500 are exempt from state sales tax. Participating localities may also waive their local taxes. Missouri also has a Show-Me Green sales tax holiday for Energy Star-certified appliances.
Filing and Compliance for Missouri Sales Tax
The Missouri Department of Revenue (DOR) administers state and state-collected local sales taxes through a single return. Businesses register for a Sales Tax License through the MyTax Missouri portal (no cost). Filing frequency: monthly (annual liability over $900), quarterly ($90–$900), or annually (under $90).
Missouri adopted economic nexus effective January 1, 2023, requiring remote sellers with more than $100,000 in annual Missouri sales to collect and remit sales tax. Missouri was one of the last states to adopt economic nexus after the Wayfair decision.
| Filing Detail | Requirement |
|---|---|
| Economic nexus threshold | $100,000 in annual Missouri sales |
| Marketplace facilitator rule | Yes — effective January 1, 2023 |
| Filing frequency | Monthly, Quarterly, or Annual |
| State agency | Missouri Department of Revenue |
| Timely filing discount | 2% of tax collected (up to $500/month) |
| Late filing penalty | 5% of tax due per month (up to 25%) |
| Sourcing method | Origin-based |
Missouri uses origin-based sourcing, meaning the tax rate is determined by the seller's location rather than the buyer's delivery address. This is the opposite of most states. Missouri also offers a timely filing discount of 2% of collected tax (capped at $500 per month) to incentivize on-time filing and payment — a meaningful benefit for high-volume sellers.
