Missouri runs two sales tax holidays a year: the back-to-school weekend that always opens on the first Friday in August, and a full week every April when Energy Star appliances come tax-free.
August 7–9, 2026
Friday, August 7 through Sunday, August 9
2027 dates aren't posted yet — by law the holiday always runs from the first Friday in August through that Sunday, and the Department of Revenue confirms each year's weekend on its holiday page in summer.
Do online orders count?
Yes — an online or mail order qualifies when you buy and pay for the item during the holiday, even if delivery comes after the weekend ends.
| Item | Price cap | Tax status |
|---|---|---|
| Clothing & footwear $100 or less per article — an item priced at exactly $100 still qualifies, and cloth for school uniforms counts too | $100 | Exempt |
| School supplies the $50 limit runs per purchase of supplies, not per pencil | $50 | Exempt |
| Textbooks, notebooks, book bags & backpacks the state files these under school supplies, so they share that $50 limit | $50 | Exempt |
| Personal computers, tablets & peripherals $1,500 or less per item — printers, monitors, keyboards, mice and speakers count | $1,500 | Exempt |
| Computer software | $350 | Exempt |
| Graphing calculators | $150 | Exempt |
| Watches, jewelry, handbags & umbrellas | — | Not exempt |
| Scarves, ties, headbands & belt buckles state law leaves these out of its definition of clothing | — | Not exempt |
| Radios, CD players, headphones & sporting equipment | — | Not exempt |
| Phones, copiers, office equipment & furniture | — | Not exempt |

April 19–25, 2027
Monday, April 19 through Sunday, April 25
No guessing on this one — state law pins the holiday to April 19 through April 25 every single year, so the 2027 week is already on the calendar.
Do online orders count?
Yes — buy and pay during the seven days and the appliance qualifies, even if it's delivered or installed weeks later.
| Item | Price cap | Tax status |
|---|---|---|
| Energy Star clothes washers & dryers | $1,500 | Exempt |
| Energy Star refrigerators & freezers | $1,500 | Exempt |
| Energy Star dishwashers | $1,500 | Exempt |
| Energy Star air conditioners & furnaces | $1,500 | Exempt |
| Energy Star water heaters | $1,500 | Exempt |
| Energy Star ovens, ranges & stoves | $1,500 | Exempt |
| Appliances without the Energy Star label the label is the whole test — a model that misses it pays full tax | — | Not exempt |
| Microwaves, dehumidifiers & humidifiers | — | Not exempt |
| Ice makers, water softeners & wine coolers | — | Not exempt |
| Coffee makers, bread machines & deep fryers | — | Not exempt |

August 7–9, 2026, from 12:01 a.m. Friday to midnight Sunday. State law fixes it as the first Friday in August through that Sunday, so 2027's should land the same way.
Yes. Personal computers and their peripherals qualify at $1,500 or less per item, computer software at $350 or less, and graphing calculators at $150 or less.
No total limit on the cart. The caps are per item — clothing at $100 or less each, computers at $1,500 or less each. School supplies are the odd one out: that $50 limit applies per purchase of supplies rather than per item.
Yes. Since January 1, 2023 both Missouri holidays skip state and local sales and use tax everywhere in the state, so you don't need to check whether your town opted in.
Yes — order and pay during the holiday and the exemption sticks, even if the delivery shows up the following week.
A separate seven-day holiday every April 19–25 on Energy Star certified new appliances — washers, dryers, fridges, freezers, dishwashers, water heaters, ovens, air conditioners and furnaces — with the first $1,500 of each appliance tax-free.
