A bill for an act relating to the administration of tax returns by the department of revenue, and including effective date and retroactive applicability provisions.

HF 497 allows Iowa taxpayers to round amounts to the nearest whole dollar when filing tax returns, but requires consistent rounding for all entries. Specifically, taxpayers may round calculated totals to whole dollars after including cents during the calculation process, but must round every entry on the return to whole dollars. The bill applies retroactively to tax years beginning on or after January 1, 2025, affecting all Iowa taxpayers filing returns under the Department of Revenue's administration. This change simplifies reporting for small dollar amounts without altering tax liability calculations.
