Taxes, Business - As introduced, authorizes the commissioner of revenue to change the due date of the taxpayer's business tax return to a date that is not less than 60 calendar days, rather than two calendar months, following the end of the taxpayer's business tax period for purposes of the commissioner changing a taxpayer's business tax period to correspond to the taxpayer's fiscal year. - Amends TCA Title 67, Chapter 4, Part 7.

HB 526 changes Tennessee's Business Tax Act to require that business tax returns be due no sooner than 60 calendar days after the end of the tax period, instead of the current two-month standard. This applies specifically when the commissioner of revenue adjusts a business's tax period to match their fiscal year. The bill directly affects Tennessee businesses that file annual or periodic business tax returns by standardizing the filing deadline to a clear 60-day window. The amendment takes effect July 1, 2025, with no change to the overall filing timeline (as 60 days approximates two months).
