Before you can collect and remit sales tax in Kansas, you’ll need to apply for a Kansas sales tax permit through the Department of Revenue. Whether you’re a local business, remote seller crossing economic thresholds, or operating on tribal land, the right permit—and the right setup—matters.
From selecting the correct account type to filing zero returns and formally closing your permit if needed, Kansas has its own compliance rules that are easy to overlook. That’s why many businesses turn to Hands Off Sales Tax (HOST) to manage registrations, filings, and compliance from start to finish.
Do You Need a Kansas Sales Tax Permit?
Starting with nexus is key to determining whether a Kansas sales tax permit is required.
Kansas law defines physical nexus as having in-state operations like a warehouse, office, employees, contractors, or inventory stored in Kansas. This presence triggers the obligation to register and collect tax on retail transactions.
Economic Nexus – Remote Sellers
Kansas has an economic nexus threshold of $100,000 in gross sales to Kansas customers, evaluated in the current or preceding calendar year. Unlike some states, Kansas does not still require 200+ transaction counts—sales alone suffice. This includes sales of tangible goods, digital products, taxable services, and exempt sales.
Marketplace Sellers & Tribal Exceptions
Registered marketplace facilitators are responsible for collecting and remitting tax, reducing direct obligation for remote sellers when transacting through platforms. However, sales to enrolled tribal members on tribal lands may be tax-exempt if supported by Form ST‑28 issued by the Kansas Department of Revenue. Retailers must retain these certificates to document the exemption.
Nexus Summary Table
| Nexus Type | Trigger Conditions | Permit Requirement |
| Physical Nexus | Presence in Kansas—employees, warehouse, inventory | Yes, state permit required |
| Economic Nexus | $100K+ in Kansas sales (current or prior year) | Yes, state permit required |
| Marketplace Sales | Sales via registered facilities | Facilitator collects, not you |
| Tribal Exempt Sales | Sales to enrolled tribal members with ST‑28 certificate | Permit may still be required |
A sales tax permit must be obtained before collecting tax or issuing resale certificates. And even if exempt buyers use ST‑28, your business must register if nexus thresholds are met.
Step‑by‑Step Registration via Kansas Department of Revenue
Before registering for a Kansas sales tax permit, make sure you’ve gathered all necessary information. Then, choose either online submission or the paper application to begin the process.
Pre‑Registration Checklist

Filing Obligations & Permit Maintenance
Keeping your Kansas sales tax permit compliant means staying current on filing duties, understanding that renewals aren’t needed, and knowing the risks of missing required returns.
No Permit Renewal Required

Filing Frequency & Zero-Return Requirement
Kansas assigns your filing frequency based on estimated or actual tax liability:
- Annual if tax due ≤ $1,000
- Quarterly for $1,000–$5,000
- Monthly for > $5,000 (or more frequent if designated as a prepaid filer)
Regardless of sales activity, you must file a return every period, even if it’s zero. Missing zero-return filings may trigger penalties or account suspension.
Late Filing Risks & Responsibilities
- Kansas imposes penalties and interest on unpaid tax, which grow the longer a return is late.
- Even without sales, failing to submit by the due date can lead to compliance issues or portal access removal.
- You’re also expected to record keep exemption certificates and tax documents for audit purposes if needed.
Summary Table
| Requirement | Details |
| Permit Renewal | Not required—valid until closure or change |
| Filing Frequency | Determined by annual tax liability |
| Zero-Return Obligations | Always required, even during no-sales periods |
| Late Filing Penalties | Financial penalties and potential account suspension |
Staying proactive on Kansas sales tax filings, even when sales are zero, helps you avoid unnecessary fees and ensures uninterrupted compliance.
Business Closure & Account Cancellation
If you cease operations in Kansas—or stop selling taxable goods into the state—you must formally close your Kansas sales tax account. Failing to do so may expose you to future filing obligations or audit triggers.
Closing Your Account (Form CR‑108)
- Submit Form CR‑108: Notice of Business Closure to the Kansas Department of Revenue (KDOR), specifying your business closure date. This formal step terminates your account and removes the requirement to file further returns.
- Once processed, KDOR will confirm closure and discontinue your filing obligations.
Why Closure Matters
- Without closure, your sales tax permit remains active indefinitely, and KDOR may continue sending filing notices—even in periods of no activity.
- Lingering active status can trigger unnecessary penalties or miscommunication in case of audits.
Quick Closure Checklist
- File your final tax return up to and including the closure date.
- Submit Form CR‑108 via KDOR’s online portal or by mail.
- Retain confirmation of closure for your records.
Properly ending your Kansas sales tax obligations helps protect you from administrative burdens and ensures a clean closeout—without lingering risks or obligations.
Common Compliance Pitfalls in Kansas
Kansas businesses often face recurring compliance challenges—especially when it comes to sales tax filing and exemption handling. Here’s how to avoid common mistakes:
Failing to File Zero Returns
Even with no taxable sales, Kansas requires a return each period. Filing is mandatory regardless of activity. Skipping a zero return can result in penalties or account suspension.
Ignoring Account Types: Retail vs Compensating Use
During registration, it’s essential to select the correct account type—such as Retailer Sales Tax or Compensating Use Tax. Misclassification can lead to incorrect tax reporting and audit exposure.
Misreporting Tribal Exemptions
Sellers must obtain a valid Form ST‑28 from enrolled tribal members to exempt those transactions properly. Without it, exempt sales may still be taxed, exposing businesses to liability.
Entering Incorrect Sales Estimates
KDOR uses your projected sales to determine your filing frequency. Over- or underestimating can shift your filing tier—resulting in audit risk or unnecessary returns.
Leaving Your Permit Open after Closure
If you cease operations in Kansas but don’t close your tax account with Form CR‑108, your permit remains active—leading to continued filing notices and potential penalties.
Compliance At-a-Glance
| Pitfall | Risk or Consequence | Proactive Action |
| No zero-return filing | Penalties and possible account suspension | Always file—even when sales = $0 |
| Wrong tax account type | Misreporting, audit or misallocated use tax | Select correct Retailer or Compensating file |
| Improper tribal exemption handling | Tax liability on exempt sales | Collect and retain ST‑28 forms |
| Inaccurate sales estimates | Wrong filing tier; audit triggers | Update estimates annually or when sales change |
| Forgetting to close outbound permits | Continued compliance burden and notices | Submit final return and Form CR‑108 |
Staying sharp around these common issues helps you avoid penalties and maintain clean, compliant operations under Kansas sales tax law.

Frequently Asked Questions (FAQs)
1. Do I need a Kansas sales tax permit if I only sell online?
Yes—if your total sales into Kansas exceed $100,000 in the current or previous calendar year, you’re required to register for a sales tax permit, even if you have no physical presence in the state. This is Kansas’s economic nexus rule.
2. What’s the difference between Retailers’ Sales Tax and Compensating Use Tax in Kansas?
Retailers’ Sales Tax applies to in-state sales where the seller is physically present. Compensating Use Tax applies to sales delivered into Kansas by out-of-state sellers. Many remote sellers are required to register for both account types.
3. How long does it take to receive a Kansas sales tax permit?
Online applications through the Kansas Department of Revenue are typically processed within 1 to 4 weeks. Paper applications (Form CR‑16) may take longer. You’ll receive your account number and paper permit by mail.
4. Do I need to file returns even if I had no sales in a given month?
Yes. Kansas requires all registered sales tax permit holders to file zero-returns for every reporting period—even if no sales were made. Failure to file can result in penalties.
5. How do I close my Kansas sales tax account if I stop doing business?
To formally close your sales tax account, you must file a final return and submit Form CR‑108 (Notice of Business Closure). This prevents future filing obligations and audit triggers.
