Kansas is generally a rolling conformity state. This means that applicable federal tax changes, including provisions under the One Big Beautiful Bill Act (OBBBA), will automatically flow through to Kansas taxable income unless the state legislature passes a specific decoupling statute. However, Kansas 1099 filing requirements, withholding rules, reporting thresholds, and filing procedures are governed separately by the Kansas Department of Revenue and should be followed independently of federal OBBBA changes.
Kansas participates in the CF/SF program for eligible information returns. If you are required to file an information return with the federal government, you generally do not need to submit those returns separately with the Kansas Department of Revenue (KDOR). However, any form reporting Kansas income tax withholding must be filed directly with KDOR and included with the payer’s annual Form KW-3 reconciliation, regardless of federal rules or program participation. The state requires the following forms when applicable:
Nonemployee compensation paid to contractors and other service providers.
Miscellaneous payments, such as rent, royalties, awards, and prizes.
Payment card and third-party network transactions.
Interest, dividends, and certain distributions.
Distributions from retirement plans, pensions, or annuities.
Proceeds from broker and barter exchange transactions.
Certain government payments (such as unemployment compensation).
Forms 1099-OID, 1099-PATR, 1099-S, 1098, 5498, and W-2G when Kansas-source income is reported.
While Kansas participates in the IRS Combined Federal/State Filing (CF/SF) program, it can only be used if no state income tax was withheld. If any Kansas income tax was withheld, you cannot use the CF/SF program to satisfy your state obligations; you must file directly with the state. Additionally, Kansas enforces a mandatory electronic filing threshold, if submitting 51 or more W-2 or 1099 records.

Form KW-3 serves as the mandatory state-level reconciliation and transmittal return for all Kansas withholding tax accounts.
The total amount of Kansas income tax withheld from W-2s and applicable 1099 forms, reconciled with the annual withholding deposits and credits.
File Form KW-3 if you maintain an active Kansas withholding account or if you file applicable 1099 returns that report Kansas tax withholding.
Form KW-3 must be submitted electronically through the Kansas Customer Service Center (WebTax).
For a smooth filing season, platforms like 1099Online can help automate the compilation and submission of your state data alongside the required Form KW-3 withholding details.
Businesses and other payers that make reportable Kansas-related payments are required to file Forms 1099.
If Kansas income tax was withheld from a payee, the payer must file the applicable Form 1099 directly with the Kansas Department of Revenue. If no Kansas income tax was withheld, an eligible information return that was submitted and coded for Kansas through the IRS Combined Federal/State Filing Program may satisfy the Kansas filing requirement.
Before logging into the KDOR WebTax portal, ensure you have collected the following details:
This unique 15-digit number issued by the state (required for returns with withholding).
Legal names, physical addresses, and TIN (either EIN or SSN).
The total Kansas-source income, payment amount or other reportable amounts.
The total amount of state income tax withheld from the payments.
