New Income Thresholds for Senior & Disabled Exemptions

The State Legislature has increased the income thresholds for the senior and disabled citizen property tax exemption program. To qualify for this exemption, the maximum total household income is 70% of the county median household income. For Cowlitz County, this means total household income must be $54,000 or less. The new thresholds are effective with the income earned in 2023 and will be applied to the 2024 tax year
