The Topeka sales tax rate is 9.35 percent on most retail purchases, combining a 6.5 percent Kansas state tax, a 1.35 percent Shawnee County tax, and a 1.5 percent City of Topeka tax. Inside certain commercial districts the total runs as high as 11.35 percent. The Kansas Department of Revenue collects all three layers and distributes them to the state and local governments.
How the 9.35 Percent Breaks Down
Three separate taxes stack on every taxable sale in Topeka. The state portion of 6.5 percent is imposed under K.S.A. 79-3603 on retail sales of goods and certain services. Shawnee County adds 1.35 percent, and the City of Topeka adds another 1.5 percent authorized by voters under K.S.A. 12-187, with a share dedicated to street improvements and the balance flowing into the general fund.1Kansas Office of Revisor of Statutes. Kansas Code 12-187 – Countywide and City Retailers Sales Taxes
Together, those layers produce the 9.35 percent baseline that applies to a typical purchase inside city limits.
Special Taxing Districts Add 1 or 2 Percent
Dozens of Topeka locations sit inside Community Improvement Districts that layer an extra 1 or 2 percent on top of the base. A CID sales tax can be set in 0.10 or 0.25 percent increments up to a 2 percent maximum, and it funds specific development projects within the district’s boundaries.2Kansas State Legislature. Kansas Code 12-6a31 – Community Improvement District Sales Tax A restaurant inside a 2 percent CID charges the full 11.35 percent, while a store a block away outside any district charges 9.35. Several CIDs downtown and in south Topeka carry the maximum surcharge.
Because the rate can change from one side of a street to the other, the Kansas Department of Revenue publishes a free address lookup tool that returns the exact rate for any location.3Kansas Department of Revenue.

What the Tax Applies To
Kansas sales tax covers three broad categories: retail sales of tangible goods, rentals or leases of tangible goods, and labor services to install, repair, or maintain tangible property.4Kansas Department of Revenue. Pub. KS-1510 Sales Tax and Compensating Use Tax That third category is the one people miss. Hire someone to fix an appliance, replace a car alternator, or service an HVAC system, and the labor line on the invoice is taxable along with any parts.
Digital products sit outside the tax base. Kansas has not adopted the digital-product provisions used by the 24 states in the Streamlined Sales Tax Agreement, so e-books, streaming music, streaming video, and electronically delivered software are not taxed. A DVD bought at a Topeka store carries the full 9.35 percent. The same movie streamed at home carries nothing.
Exemptions Worth Knowing
Groceries
The Kansas state sales tax on food and food ingredients dropped to zero on January 1, 2025. Local taxes were not part of that phaseout, so Topeka shoppers still pay 2.85 percent on groceries (1.35 percent county plus 1.5 percent city), and more inside a special district.5Kansas Department of Revenue. Pub. KS-1223 Food Sales Tax Rate Reduction
Prescription Drugs
Prescription medications and insulin are fully exempt at both the state and local level. No exemption certificate is required at the register.4Kansas Department of Revenue. Pub. KS-1510 Sales Tax and Compensating Use Tax
Residential vs. Commercial Construction Labor
Labor to build, remodel, renovate, repair, or replace a home is exempt across the board. On commercial property, only labor tied to original construction is exempt. Remodeling an office, repairing a commercial roof, or repaving a business parking lot all involve taxable labor.6Kansas Department of Revenue. Pub. KS-1525 Business Taxes for Contractors The same scope of work can be exempt at a house and taxable at a strip mall next door.
Government and Nonprofit Purchases
Government agencies and qualifying nonprofits can buy without paying tax, but only by presenting a valid Kansas exemption certificate at the point of sale. Retailers keep those certificates on file to justify untaxed sales during an audit.4Kansas Department of Revenue. Pub. KS-1510 Sales Tax and Compensating Use Tax
Buying From Out-of-State Sellers
After South Dakota v. Wayfair, Kansas requires remote sellers to collect and remit sales tax once annual sales into the state exceed $100,000. A seller crossing that threshold must register with the Kansas Department of Revenue within 30 days and begin collecting on the next transaction.4Kansas Department of Revenue. Pub. KS-1510 Sales Tax and Compensating Use Tax Tax is calculated at the buyer’s delivery address, so a package sent to a Topeka home inside a CID carries the full district rate.
When the seller doesn’t collect Kansas tax, the obligation shifts to the buyer. Kansas calls this the compensating use tax, and it applies whenever you buy from an out-of-state seller who charged less than 6.5 percent. Individual consumers report and pay it on Form CT-10U directly to the Department of Revenue.7Kansas Department of Revenue. Consumers Compensating Use Tax Enforcement against individuals on small purchases is rare in practice. Businesses that buy equipment or supplies from out-of-state vendors face real audit risk if they skip the use tax.
Registering a Business and Filing Returns
Any business making taxable sales in Topeka needs a Kansas sales tax registration before its first transaction. Registration is free through the Department of Revenue’s Customer Service Center.8Kansas Department of Revenue. Business Registration The Department then assigns a filing frequency based on expected tax liability:
- Annual filing for total tax liability up to $1,000 per year.
- Quarterly filing for liability between $1,000.01 and $5,000 per year.
- Monthly filing for liability above $5,000 per year.9Kansas Department of Revenue. Filing Frequency Changes
Returns are filed electronically. Monthly returns are due by the 25th of the following month. As sales volume grows, the Department will move a business to a more frequent schedule automatically.
Late Filing and Nonpayment Penalties
A business that misses a return or payment owes 1 percent of the unpaid tax for each month it stays delinquent, capped at 24 percent.10Kansas Office of Revisor of Statutes. Kansas Code 79-3615 – Interest and Penalties Interest runs on top of that from the original due date. Two situations raise the stakes:
- If the Department finds no reasonable attempt to comply during an audit, the penalty jumps to 25 percent of the unpaid balance.
- Intentionally failing to pay or filing a false return carries a 50 percent penalty.10Kansas Office of Revisor of Statutes. Kansas Code 79-3615 – Interest and Penalties
Even when an audit uncovers underpayment by a business that filed and paid in good faith, a reduced penalty of 1 percent per month, capped at 10 percent, still applies to the assessed balance.10Kansas Office of Revisor of Statutes. Kansas Code 79-3615 – Interest and Penalties Filing voluntarily before the Department reaches out limits the damage.
