Riverside Bkk Property Tax Cap Referendum and Household Budget Adjustments
The July 15 ballot measure would limit annual property tax growth to inflation plus 1 percent, changing annual payments for owners of homes assessed above 400,000 local currency units.
How we reported this
Voters across Riverside Bkk wards will consider a ballot measure on 15 July that caps annual increases in residential property taxes at the inflation rate plus one percentage point for three years beginning in 2027. The measure directly covers households whose properties are assessed at or above 400,000 local currency units, which includes most single-family homes and many multi-unit buildings in the central and riverside districts.
City records show property taxes supplied 38 percent of general fund revenue in the 2025 fiscal year. Recent assessments released by the Riverside Bkk Revenue Office indicate average annual bills rose 6.8 percent between 2023 and 2025, outpacing the 3.2 percent average wage growth recorded for the same period by the local statistics bureau. The referendum therefore arrives at a moment when local officials project further assessment increases tied to ongoing infrastructure valuations.
Changes to Monthly Household Outlays
Under the proposed cap, a home assessed at 450,000 local currency units currently paying 5,400 in annual tax would see the bill rise by no more than 180 in the first year instead of the 360 previously projected. Renters in buildings that pass tax costs through leases could see smaller escalations in annual rent renewals, according to language in the draft ordinance. Local advocates note that the measure does not alter utility fees or sales taxes, which remain outside the referendum scope.
The legislation states that any revenue shortfall from the cap must be offset by drawing on the city’s existing stabilisation reserve rather than new borrowing. The 2026 budget paper allocates 12 million local currency units to that reserve, an amount city analysts say would cover the estimated 9.4 million shortfall for the first two years if the measure passes.
Next Steps After the Vote
If approved, the cap takes effect with the 2027 tax bills mailed in December 2026. The city council must then adopt implementing rules by October 2026 that specify how inflation is calculated each year using the national consumer price index. Should the measure fail, current assessment procedures continue unchanged under the existing revenue code.
Ballot materials distributed by the Riverside Bkk Election Commission list the measure as Proposition 3 and include a plain-language summary of the three-year duration and the inflation-plus-one limit. Residents can review the full text at the commission’s offices on Riverside Avenue until 10 July.
