What changes

  • BeforeThe Department of Revenue assessed and collected fees from counties, cities, towns, councils of governments and certain regional transportation authorities for its integrated tax system modernization project through June 30, 2028.

    NowThese fees continue through June 30, 2030.

  • BeforeThe fee applied to councils of governments that receive revenues under one state law (section 42-6105).

    NowThe fee also applies to councils of governments that receive revenues under section 42-6105.01, and unpaid amounts can be withheld from those distributions too.

  • BeforeTransfers to the project fund from the education sales tax monies and from the tax under section 42-5452 were allowed through June 30, 2028.

    NowThese transfers continue through June 30, 2030. The amount from the education sales tax monies "shall be transferred" to the project fund, as determined by the department's director.

  • BeforeSection 42-1009, added by a 2022 law, was set to be repealed after December 31, 2029.

    NowThat section is now set to be repealed after December 31, 2031.

  • NowFor fiscal year 2026-2027, the Legislature states its intent that total fees on all local governments covered not exceed $1,273,800, shared among counties, cities and towns, councils of governments and regional transportation authorities based on what each group received in state distributions 2 years earlier. It also states its intent that the education sales tax transfer not exceed $154,500 and the section 42-5452 tax transfer not exceed $34,400.
