Kansas Sales Tax and Invoicing Rules for 2026

TL;DR: Kansas levies a 6.5% state sales tax with local taxes pushing combined rates above 10% in some areas. Remote sellers exceeding $100,000 in sales must collect. Kansas eliminated the state-level grocery tax effective 2025, but local grocery taxes may still apply.

Kansas recently made a significant change by eliminating the state-level tax on groceries, but the complex local tax landscape means food is still partially taxed in most areas. Combined rates in some Kansas jurisdictions exceed 10%, creating compliance challenges for multi-location sellers. This guide covers Kansas's rates, nexus rules, invoice requirements, exemptions, filing deadlines, and penalties for 2026.

State sales tax rate

Kansas imposes a 6.5% state sales and use tax on the retail sale of tangible personal property and certain services. Cities, counties, and special districts add local taxes that can bring the combined rate to 10% or higher in certain jurisdictions. Wichita's combined rate is approximately 7.5%, while some smaller jurisdictions exceed 10% due to stacked special-purpose taxes. Kansas reduced and then eliminated the state-level tax on groceries through phased legislation, reaching 0% at the state level by January 2025.

The high combined rates in some areas make Kansas one of the more expensive states for sales tax in certain jurisdictions. Sellers should use the Department of Revenue's rate lookup tools to determine the correct rate for each delivery location.

Nexus rules

Physical nexus is created by having a business location, employees, agents, inventory, or property in Kansas. Delivering goods into the state with your own vehicles also establishes nexus.

Economic nexus applies to remote sellers with $100,000 or more in gross revenue from sales into Kansas. There is no separate transaction count threshold. Kansas is a member of the Streamlined Sales and Use Tax Agreement (SSUTA), which provides centralized registration and compliance tools. Marketplace facilitators must collect and remit on behalf of third-party sellers once the facilitator exceeds the threshold.

What must appear on invoices

The Kansas Department of Revenue expects invoices to include:

• Seller's name, address, and Kansas sales tax registration number
• Buyer's name and address
• Date of sale
• Itemized description of each product or service
• Sale price before tax
• Sales tax amount shown separately
• Applicable combined state and local rate
• Total amount due including tax
• Exemption certificate number for tax-free sales

Since local rates vary substantially across Kansas, sellers must ensure they are applying the correct jurisdiction-specific rate, especially for deliveries to different Kansas locations. Retaining delivery address documentation is essential for supporting the rate applied during audits.

Exemptions and special cases

Kansas provides the following exemptions:

• Groceries (unprepared food) are exempt at the state level as of 2025; local taxes on groceries remain in effect
• Prescription drugs and durable medical equipment
• Sales to federal, state, and local government entities
• Agricultural machinery and inputs used in farming and ranching
• Manufacturing machinery and raw materials consumed in production
• Sales to qualifying 501(c)(3) nonprofits with a Kansas exemption certificate
• Motor fuels (subject to a separate fuel tax)

Clothing is fully taxable in Kansas at the full combined rate. Most services are not taxable unless they involve fabrication or repair of tangible property. Digital products and SaaS are generally not taxable in Kansas, though prewritten software delivered on tangible media is taxable. Prepared food and restaurant meals are taxable at the full rate.

Filing frequency and deadlines

Kansas requires electronic filing through the Kansas Customer Service Center. There is no vendor discount for timely filing. Returns must be filed for all periods even if no tax was collected. If a due date falls on a weekend or holiday, the deadline moves to the next business day.

Penalties for non-compliance

A penalty of 1% per month of unpaid tax applies for late filing, up to a maximum of 24%. A separate negligence penalty of 25% may apply in cases of underpayment due to disregard of rules. Interest accrues at the statutory rate (typically around 4% to 6% per annum). Operating without a required sales tax registration can result in additional fines. Kansas can assess taxes going back to the date nexus was established plus all accumulated penalties and interest.

Frequently asked questions

Are groceries still taxed in Kansas? At the state level, groceries became fully exempt in January 2025. However, local jurisdictions may still impose their local sales tax on groceries, so some tax may appear on food purchases depending on where you shop. The local grocery tax can range from 1% to over 4% depending on the jurisdiction.

Does Kansas tax SaaS or digital products? Kansas generally does not tax SaaS or digital products delivered electronically. Prewritten software on tangible media (like a CD or USB drive) is taxable as tangible personal property. Custom software developed for a specific customer is exempt. This makes Kansas relatively favorable for digital businesses.

Is Kansas a Streamlined Sales Tax state? Yes. Kansas is a full member of the SSUTA, allowing remote sellers to register through the centralized system and access rate databases, boundary files, and simplified compliance tools for multi-state selling.

Are shipping charges taxable in Kansas? Yes. Kansas treats shipping and handling charges as part of the taxable sale price when they are incurred in connection with the sale of taxable goods. This applies whether shipping is separately stated or bundled into the price. Sellers should include shipping in their taxable amount calculations.
