On March 21, 2025, Washington State introduced Senate Bill 5798, aimed at reforming the penalties and notification processes associated with delinquent property taxes. The bill seeks to alleviate the financial burden on taxpayers, particularly those in vulnerable housing situations, while enhancing communication regarding tax obligations.

One of the key provisions of Senate Bill 5798 is the introduction of an additional penalty of eight percent on delinquent tax amounts, which will be assessed on December 1 of the year the tax is due. However, the bill notably exempts residential properties with four or fewer units, including manufactured and mobile homes, from these penalties. This exemption is designed to protect low-income homeowners and renters from excessive financial strain.

Furthermore, the bill establishes guidelines for county treasurers regarding the assessment of penalties for taxpayers engaged in payment agreements. If a taxpayer is actively participating in a payment plan, additional penalties on the delinquent taxes covered by that agreement cannot be imposed. However, any interest or penalties accrued prior to the agreement will still be owed.

Senate Bill 5798 also mandates that county treasurers notify taxpayers of their delinquent status, providing detailed information on current and overdue taxes, penalties, and contact information for resources such as the statewide foreclosure hotline. This requirement aims to ensure that taxpayers are well-informed about their obligations and available assistance.

The bill has sparked discussions among lawmakers and stakeholders, particularly regarding its potential impact on housing stability. Advocates argue that the reforms could prevent foreclosures and support low-income families, while some critics express concerns about the financial implications for local governments reliant on property tax revenue.

As the legislative process continues, the significance of Senate Bill 5798 lies in its potential to reshape how delinquent property taxes are managed in Washington State. If passed, it could provide much-needed relief to struggling homeowners and renters, while also prompting a reevaluation of tax collection practices across the state. The bill's future will depend on ongoing debates and amendments as it moves through the legislative process.
