How Are Property Taxes Calculated in Delaware?

Delaware property taxes are calculated by multiplying the assessed value of the property by the local tax rate. The assessed value is determined by county assessors based on a periodic review of property conditions, comparable sales, and valuation approaches.

Assessment Process

Local assessors update property values every few years, though the exact interval depends on the county. They use market data, property characteristics, and sometimes income or cost methods to estimate value. Discrepancies between assessed value and actual market value may occur, so reviewing assessment notices carefully is critical.

Tax Rate Determination

Each local government sets its property tax rate based on budget demands, including education, public safety, and infrastructure funding. These rates are expressed per $100 or $1,000 of assessed value and can fluctuate annually. Securing the current tax rate from the county auditor or treasurer’s office is essential for accurate tax projections.
