K-40 Form
Use a K40 Form 2020 template to make your document workflow more streamlined.
What the K-40 Form is used for
The K-40 Form is Kansas’s individual income tax return for reporting a taxpayer’s state income tax information to the Kansas Department of Revenue. A taxpayer generally completes identifying information, filing status, income, adjustments, credits, tax, payments, and the declaration and signature areas shown on the applicable K-40 instructions. signNow can help prepare a fillable K-40 PDF, route signature fields, and preserve the completed record with an audit trail. It does not replace Kansas filing instructions or confirm that the Department of Revenue accepted the return.
How the K-40 workflow works
Prepare the Kansas return in signNow, verify its tax data separately, then capture signatures and preserve the completed record.

K-40 Form workflow features
The K-40 workflow combines fillable document preparation, controlled signing, audit evidence, and secure handling of Kansas tax records.
Fillable PDF
Upload the K-40 PDF and use signNow fields for taxpayer names, dates, amounts, declarations, and signatures without rebuilding the return from scratch.
Signer routing
Route the prepared K-40 to the taxpayer, spouse, or authorized preparer in the required order, reducing email attachments and misplaced versions.
Audit trail
Capture signer actions, timestamps, and document history in an audit trail that can accompany the retained K-40 record during internal review.
Controlled storage
Keep the completed Kansas return in a controlled signNow workspace with permissions that limit access to taxpayer information and signed tax records.
Mobile review
Use signNow mobile apps when a taxpayer or preparer reviews the K-40 away from a desktop, while maintaining the same document workflow.
Named integrations
Connect K-40 preparation to Google Drive, Microsoft 365, or NetSuite workflows when document storage or accounting coordination requires a named integration.
Legal standing of a signed K-40
Electronic signing can support the K-40 record under ESIGN and applicable Kansas electronic-transactions law when intent, consent, attribution, and record retention are established. The signed record does not override Kansas Department of Revenue filing rules, and ESIGN exceptions include wills, certain court filings, and family-law decrees.
K-40 Form troubleshooting questions
These answers address preparation, electronic signing, Kansas submission, and record-control issues for the K-40 Form.
Upload the current K-40 PDF to signNow, place required taxpayer and preparer fields, then verify every amount against Kansas Department of Revenue instructions before signing.
The Business plan includes templates, legally binding eSignatures, and audit trails at $8/user/month when billed annually. Business Premium adds bulk send at $15/user/month.
A signed K-40 record does not prove Kansas filing acceptance. Retain the completed document and separately follow Kansas Department of Revenue submission instructions.
For consumer-facing electronic records, provide the ESIGN disclosure, confirm electronic access, and explain withdrawal procedures under 15 U.S.C. §7001(c).
Use signNow SMS authentication or another configured signer verification method when taxpayer identity needs stronger evidence than an email link alone.
Protect taxpayer information through role-based access, audit-trail review, and controlled downloads. signNow supports ISO 27001, SOC 2 Type II, GDPR, and ESIGN/UETA compliance.
