Kansas re-released its K-99CSV specifications with a 1099-DA format, making it the first state to post custom 1099-DA (digital asset transactions) electronic filing specifications for tax year 2025 reporting. Kansas requires brokers to file Form 1099‑DA if the form reports Kansas income tax withholding or is required to be filed with the IRS.
Kansas generally follows IRS Publication 1220 for 1099 filing, but allows filers that cannot meet those requirements to use its custom CSV format. Because Form 1099‑DA is not supported in the FIRE system or Publication 1220 and is not part of the Combined Federal/State Filing program for tax year 2025, brokers that need to report Form 1099‑DA to Kansas must use the Kansas CSV layout.
