Bill Overview
Analyzed Economic Effects
3 provisions identified: 0 benefits, 2 costs, 1 mixed.
More value added after urban renewal ends
Beginning January 1, 2026, when an urban renewal area ends, the roll may add only the increment above the area’s 2006 incremental value, or add 80% of the increment if the area was formed after December 31, 2006. When base value rises because prior increment is moved to base or from a de‑annexation, the roll adds 80% of the amount above the 2006 incremental value, or the full increment if the area formed after 2006. For fire or ambulance districts that withdraw, 80% is added in the withdrawal year and 90% of otherwise qualifying new construction in later years; districts not subject to financing rules include 90%. These additions raise the taxable base for owners in the affected districts.
New power generation builds are taxed
Beginning January 1, 2026, new construction or installation of equipment used to generate electricity is added to the new construction roll. Property allocated or apportioned under section 63-405, property owned by a cooperative, municipality, or public utility as defined in section 61-332A, and any replacement equipment are excluded. If your project is included, the added value can increase your property tax.
Most new construction value is taxed
Beginning January 1, 2026, county assessors count 90% of qualifying new‑construction value on the new construction roll. The law counts only value caused by the build itself, not general market or inflation gains. It subtracts prior five‑year value cuts ordered by a court or board, fixes for double assessments, certain homestead reductions, and reductions tied to section 63-602W(4). It also excludes projects with a provisional exemption under section 63-1305C and projects that received a sales and use tax exemption under section 63-3622VV. These rules can raise or lower the value used to set your property tax.
