The Shawnee County sales tax rate is 7.85% in unincorporated parts of the county and 9.35% inside Topeka city limits. That total combines Kansas’s 6.5% state rate, a 1.35% countywide tax, and, in Topeka, a 1.5% city tax. A handful of shopping districts carry higher rates, and groceries now follow a different formula than other goods. Here is how the pieces fit together on an actual receipt.
How the Rate Is Built
Every taxable purchase in the county carries at least two layers. Kansas imposes 6.5% on most retail transactions statewide. Shawnee County adds its own 1.35% on top, which brings the floor to 7.85% even where no city tax applies.
Topeka, the county seat, layers another 1.5% city sales tax, producing the standard 9.35% rate most residents see. The county’s authority to levy its local tax comes from K.S.A. 12-187, which lets counties impose a retailers’ sales tax in quarter-percent increments, with legislative approval required above 1%.
Smaller cities inside the county set their own rates, so a delivery to Silver Lake, for example, carries Silver Lake’s combined rate rather than Topeka’s.
Where the Rate Runs Higher
Certain shopping areas within Topeka sit above the standard 9.35%. Community Improvement Districts and STAR bond project zones add surcharges that fund specific developments. Several Topeka CIDs push the total to 10.35%, and a handful reach 11.35%. STAR bonds are a form of tax-increment financing in which a city issues revenue bonds repaid by the additional sales and use tax collected inside the designated area.
If a store sits inside one of these zones, the register applies the higher rate automatically. You can confirm the rate for any Kansas address through the Kansas Department of Revenue’s quarterly rate publications or its online address lookup tool.
Groceries After the 2025 Change
Kansas eliminated its state-level sales tax on food and food ingredients on January 1, 2025, completing a phased reduction that began in 2023. The state rate on qualifying groceries is now 0%.
Groceries are not tax-free in Shawnee County, though. The repeal applied only to the state’s 6.5% share. Local taxes remain in effect on food purchases, including the 1.35% county tax and any city tax. In Topeka that means groceries carry a combined local rate of 2.85%. Where a special district surcharge applies, it stacks on top of that.
What Gets Taxed
Kansas applies sales tax to two broad categories: tangible personal property, meaning physical goods you can hold, move, or measure, and certain labor services. Services are taxable when they involve installing, repairing, servicing, or maintaining tangible personal property. Repairing a lawnmower, servicing a vehicle, and installing new flooring are all taxable.
Kansas uses destination-based sourcing to decide which local rate applies. For items picked up in person, the rate at the store’s location controls. For shipped or delivered goods, the rate at the delivery address controls. For taxable services, the rate at the location where the buyer first uses the service applies. A Topeka retailer shipping furniture to a home in unincorporated Shawnee County collects 7.85%, not the 9.35% Topeka rate. A Topeka retailer shipping to Wichita collects the Wichita rate.
Who Can Buy Without Paying Tax
Several categories of purchases are exempt from Kansas sales tax, and the exemption flows through to the county and city portions as well.
- Nonprofits and religious organizations exempt from federal income tax under Section 501(c)(3) that purchase goods exclusively for religious purposes. Public and private schools and nonprofit educational institutions qualify on purchases used for nonsectarian programs.
- Agricultural production inputs under K.S.A. 79-3606(t), including farm machinery and equipment, repair parts and labor to maintain them, feed for livestock raised for food production, seeds and fertilizer used in crop production, and propane used for agricultural purposes.
- Resale inventory. Retailers buying goods they intend to resell do not owe tax on the purchase; the tax is collected later when the item sells to the end consumer.
To claim any exemption, the buyer gives the seller a Kansas Exemption Certificate. The general-purpose form is ST-28, with specialized versions for resale, agricultural production, and contractor purchases. Tax-exempt entities assigned a Kansas Exemption Number use Form PR-78 instead. Sellers must keep completed certificates on file. If a seller cannot produce a valid certificate during an audit, the sale is treated as taxable and the seller becomes liable for the uncollected tax.
Buying From Out of State
When you buy something from an out-of-state seller that does not charge Kansas sales tax, you owe Kansas compensating use tax on the purchase. This covers online orders, catalog purchases, and items you physically bring back from another state. The tax is calculated on the full cost of the goods, including shipping and handling.
If the seller charged another state’s sales tax at a rate lower than Kansas’s 6.5%, you owe the difference. Local use taxes from your city and county apply on top. Labor services bought from out of state are not subject to compensating use tax, but tangible goods are. Individual consumers report and pay the tax on their Kansas income tax return. Businesses registered for sales tax report it on their regular return.
Out-of-state businesses selling into Kansas must collect and remit Kansas sales tax once they exceed $100,000 in cumulative gross receipts from Kansas sales during the current or immediately preceding calendar year, under K.S.A. 79-3702(h). That threshold counts all sales to Kansas customers whether the specific items are taxable or exempt.
Collecting and Filing as a Business
Any business making taxable sales in Kansas needs a sales tax registration before its first transaction. The process starts with the Kansas Business Tax Application, Form CR-16, through the Kansas Department of Revenue. The application asks for a Federal Employer Identification Number, a NAICS code, and personal information for principal officers or owners. Once the state processes the form, the business receives its Kansas sales tax account number and a filing frequency.
Kansas assigns filing frequency based on annual sales tax liability:
- Annual filers owe $1,000 or less per year and file once, due January 25 of the following year.
- Quarterly filers owe between $1,000.01 and $5,000 per year and file on the 25th of the month after each quarter ends: April 25, July 25, October 25, and January 25.
- Monthly filers owe more than $5,000 per year and file on the 25th of the following month.
Returns go through the Kansas Department of Revenue’s Customer Service Center portal. Payment options include ACH debit through the portal, ACH credit initiated through your bank, credit card through the KDOR Tax Payment Portal, or a mailed check with a printed voucher. Kansas requires electronic filing for sales and use tax returns.
Missing a deadline is costly. Kansas charges a penalty of 1% per month on any unpaid balance, capping at 24%. Interest accrues separately at a rate set annually by the Department of Revenue; the 2026 rate is 8% per year, roughly 0.67% per month. Penalties on amounts discovered in a field audit cap at 10% instead of 24%. A typical field audit covers a three-year lookback, extendable by written agreement, and reviews whether the business collected the correct rate on each transaction, whether exemption certificates are on file for every exempt sale, and whether use tax was paid on the business’s own purchases. Kansas requires businesses to keep sales tax records, including exemption certificates, invoices, and returns, for the full period the department may audit, with three years as a practical minimum.
For deliveries, the Department of Revenue’s address lookup tool returns the correct combined rate for any Kansas address. Using it on every shipment is the cleanest way to stay on the right side of destination sourcing.
