What Sussex County’s Reassessment Means for Your Tax Bill

Nov 5, 2026 · @Beth

If you’re buying at the Delaware beaches, one question comes up at almost every showing: “What will my property taxes be?” Since Sussex County finished its first full reassessment in about 50 years, the answer looks different than it used to. The good news: a much higher assessed value does not mean a much higher tax bill. Here’s what changed and what it means for you.

What happened: the first reassessment since the 1970s

For decades, Sussex County taxed property based on values set back in the 1970s. A court-ordered reassessment, which grew out of a 2018 lawsuit over education funding, changed that. The county began revaluing every residential, agricultural and commercial property in 2021.

Nearly 200,000 properties were revalued. New assessments are based on fair market value as of July 1, 2023, meaning roughly what the property could have sold for at that time. Fewer than 1% of owners requested a formal appeal hearing, and the new values were used for tax bills starting with the 2026 fiscal year.

Higher value doesn’t mean a higher bill

When assessed values went up, tax rates came down. The goal of a reassessment is to spread the tax burden fairly, not to raise more money. Delaware law backs that up with caps on how much extra revenue can be collected after a reassessment:

• Sussex County: no more than 15% above the prior year
• School districts: no more than 10% above the prior year

A county official explained it with a simple example. Say a home was assessed at $25,000 in 1974 and is now assessed at $250,000, ten times higher. If the tax rate drops from 0.36 to 0.036, also by a factor of ten, the tax bill stays the same: $90.

That’s exactly what happened to the county’s own rate. It used to be 44.5 cents per $100 of assessed value. After the reassessment, it dropped to 2.14 cents per $100, and the county kept it unchanged in its 2027 budget.

That said, not every bill stayed flat. Homes whose values rose faster than their neighbors’ may pay more now, and some pay less. That’s the “equalizing” part of a reassessment.

Where your tax dollars go

Most of a Sussex County tax bill goes to schools. A county official has noted that about 90% of property taxes are school taxes, which includes your local school district and Sussex Tech. That’s why the school district your property sits in matters more to your bill than the county rate does.

A typical bill can include:

• School district tax (the largest share)
• Sussex County tax (2.14 cents per $100 of assessed value)
• Municipal tax if the property is inside town limits, such as Rehoboth Beach or Lewes
• Water and sewer charges where county districts serve the property

One newer item for buyers of new construction: starting with the 2027 budget, the county added a school surcharge on building permits of $5 per $1,000 of construction value. If you’re buying from a builder, it’s worth asking how that cost is handled.

What buyers should do before making an offer

1. Don’t rely on the seller’s old tax bill alone. Ask for the most recent bill, which reflects the new assessment.
2. Look up the parcel. Sussex County’s online, parcel-specific tax calculator shows how a property’s bill is figured and compares it to the prior year.
3. Confirm the school district and town. Two homes a mile apart can have different bills if one is inside town limits or in a different district.
4. Know the calendar. Sussex County tax bills go out each August and are due by September 30. At settlement, taxes are typically prorated between buyer and seller.
5. Ask about credits. Delaware offers school property tax credits for certain seniors and disabled veterans who qualify. Check eligibility with the county before you budget.

Delaware’s property taxes are still low compared with many of the places our buyers move from, but they should be part of your monthly budget from day one.

What sellers should know

Buyers are doing their homework, so have your current tax bill ready when you list. If your new assessment seems out of line, Sussex County has reopened its appeal window each winter since the reassessment. Check the county’s website early in the year for the current deadline.

A clear, accurate tax figure in your listing removes one more question mark for buyers, and fewer question marks mean smoother negotiations.
