About the Castle Rock Property Market
Castle Rock is a city located in Dakota County, Minnesota. Every property inside the Castle Rock city limits is assessed by Dakota County Assessor, which applies Minnesota property tax rules uniformly across the county.

Homeowners who believe their Castle Rock home is over-assessed have the right to file a appeal directly with Dakota County Assessor before the April 30 deadline.
Minnesota allows the assessor to defend or adjust the assessed value during a appeal, so Castle Rock homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Castle Rock Property Market Context
Castle Rock homeowners navigate the same Minnesota assessment system as every other community in the state, but local market dynamics mean over-assessments here have their own character.
Minnesota market character
Minnesota assessments are set each January 2 and reflect estimated market value. The state uses a classification system that taxes different property types at different rates, and mass appraisal errors on residential homesteads are common in Twin Cities suburbs.
How Minnesota handles appeals
Minnesota homeowners can appeal via Open Book meetings, the Local Board of Appeal and Equalization, or directly to Minnesota Tax Court. The state offers both regular and small-claims tracks.
When to file in Castle Rock
Local Board of Appeal meets in April. Tax Court petitions must be filed by April 30 of the year the tax is payable.
