Mission Statement
Our mission is to serve the citizens of Skagit County through fair, transparent, and data-driven property assessment. We strive for excellence in equity, efficiency, and professionalism while building public trust through innovation, education, and service.
Ever wonder how property taxes are calculated? The Washington State Department of Revenue put together this short video breaking it all down. We know property taxes can be confusing, and the Skagit County Assessor’s Office is here to help! If you have any questions after watching, don’t hesitate to reach out—we’re happy to walk you through it.
Early 2026 Office Update
The Skagit County Assessor’s Office is currently conducting required six-year re
inspections in the Concrete School District and the Skagit County portion of the
Darrington School District. These inspections are mandated by Washington State
law and help ensure property assessments remain accurate and equitable.
Re-inspections were briefly paused this winter to complete flood-related
inspections, which are now finished. Regular re-inspection work has resumed,
and more than one-third of the current cycle is complete.
To improve efficiency and reduce the need for on-site visits, the office continues
to use aerial, oblique, and street-level imagery in accordance with International
Association of Assessment Officials (IAAO) guidelines. This approach supports
accurate review while limiting disruption to property owners.
Property owners with questions about their assessment are encouraged to
contact the Assessor’s Office to speak directly with an appraiser.
Looking Ahead
In 2026, the office continues investing in tools that strengthen accuracy,
efficiency, and transparency.
- Locally derived cost tables: The office is developing construction cost
tables using Skagit County sales data to better reflect local market
conditions and improve long-term equity.
- Updated street-level imagery: In partnership with Skagit County Public
Works and the City of Mount Vernon, the office is investing in updated
imagery to support future re-inspections and maintain high-quality
property records.
These improvements do not change how properties are assessed under state law.
Properties will continue to be assessed at market value using established
statutory standards.

Achieving Vertical Equity in Property Assessments
Ensuring fairness in property taxation remains a cornerstone of our mission at the Skagit County Assessor’s Office. Vertical equity, the principle that properties of all value ranges are assessed fairly and proportionally—continues to guide our work to maintain public trust and accuracy in assessment.
We are proud to share the 2025 Skagit County Vertical Equity Report, which reaffirms our commitment to equitable assessments across diverse property types and markets. Conducted using the Lincoln Institute of Land Policy’s Vertical Equity App, this analysis demonstrates that Skagit County continues to lead the way in consistent, data-driven valuation.
 Key Highlights from the 2025 Report:
- Median Assessment-to-Sale Ratios (ASR): 0.943, showing exceptional consistency across all sales deciles.
- Price-Related Differential (PRD): 1.007, within the IAAO-recommended range, confirming equity between lower- and higher-valued properties.
- Coefficient of Price-Related Bias (PRB): 0.002, indicating no systemic bias by price level.
We invite you to explore the full report and learn more about how Skagit County continues to set the standard for fairness and equity in property assessments.

Presentation offering
Assessor Danny Hagen is offering to come and present on property taxes and how they are administered in the State of Washington. If you are a part of a group or know of a group that has questions regarding the assessment process, please reach out to our office. Danny is quite flexible and accommodating for any group wanting to have a better understanding of local taxes.
The 2019 state legislature passed ESSB 5160, which changed the income thresholds specific to each county based on percentage of the median household income of the county. The residency requirement has also changed to a minimum of nine months out of the year. As a result, Skagit County’s new income limits are as shown below:
| Levels of Reduction for 2020 Taxes* |
Percentage of Median Household Income |
| A Income=0-$30,000 Exempt from regular property taxes on $60,000 or 60% of the valuation, whichever is greater, plus exemption from 100% of excess levies. |
45%
(
based on $65,216*)
|
| B Income=$30,001-$35,869 Exempt from regular property taxes on $50,000 or 35% of the valuation, whichever is greater, not to exceed $70,000, plus exemption from 100% of excess levies. |
55%
(
based on $65,216*)
|
| C Income=$35,870-$42,390 Exempt from 100% of excess levies. |
65%
(
based on $65,216*)
|
| *Median household income reported by the Office of Financial Management |
These new thresholds apply to 2019 income for tax relief in 2020. The new law provides adjustment to the income limits every five years. The Senior Citizen and Disabled property tax deferral program also has a new qualifying threshold of $48,912 (75% of median household income). For information on these tax relief programs, please see links to DOR publications on this site or call the Assessor’s Office at (360) 416-1780.
