What drives your Delaware property tax bill
Assessed value
Tax is applied to assessed value, which may be a fraction of market value. Use the assessment-ratio field when you know the local practice.
Local levies
School, city, county, and special districts stack. The 0.54% figure is a statewide effective average—not a single millage.
Exemptions & caps
Homestead, senior, veteran, and agricultural programs can shrink the taxable base. Assessment caps can also lag market prices after a purchase.
Reassessment timing
A sale or periodic revaluation can jump the bill. Budget with a post-purchase assessment in mind when shopping in Delaware.
Practical tips before you buy in Delaware
Pull the parcel record
Look up the address for current assessed value, exemptions on file, and last sale. Compare that to list price before you offer.
Ask for a tax estimate at closing
Lenders and title companies often quote a first-year escrow. Re-run this calculator with their assessed-value assumption.
Model monthly escrow
Divide annual tax by 12 for a rough escrow add-on to PITI. On a $400k Delaware home, that is about $180.00/mo here.

Delaware property tax FAQs
Delaware's Tax Foundation statewide effective rate is 0.54%, ranking #40 from highest to lowest. It is a comparable benchmark—not every local millage. Use the calculator above with your home value for a dollar estimate.
At 0.54% with a 100% assessment ratio and no exemption, this calculator estimates about $2,160 per year ($180.00/mo).
About $1,350 annually ($112.50/mo) under the same statewide effective-rate assumptions.
About $3,240 per year ($270.00 monthly) before local assessment quirks and exemptions.
Delaware's 0.54% rate is below the roughly 0.9% national benchmark used on this site. On a $400,000 taxable base, the annual gap vs that average is about $1,440 lower.
Often yes, when you qualify. Example: a $400,000 home with a $50,000 exemption models about $1,890/year here (taxable assessed $350,000). Confirm the exact program with the local assessor.
No. It is a statewide effective benchmark. County, city, school district, classification, caps, and exemptions can change your bill. Switch to a custom rate in the calculator if you have a tax bill percentage.
Start with expected purchase price, apply Delaware's effective rate (or a local quote), then adjust assessment ratio and exemptions. Check the parcel record for post-sale assessed value and current district levies.
Often yes via escrow—the lender collects roughly 1/12 of the annual estimate with each payment. Confirm the escrow cushion and due dates with your lender and the local tax authority.
A simple (no-inflation) cumulative estimate is about $21,600 over 10 years, or $64,800 over 30 years, if the annual bill stayed near $2,160.
Most localities allow assessment appeals with deadlines after notices. Gather comps, inspection notes, and the assessor’s valuation method. This calculator helps budget; it does not file appeals.
No. This is an educational estimate using statewide effective rates. Verify assessed value, levies, and exemptions with Delaware local officials before budgeting or closing.
