A $350,000 sale in Dover and the same sale in Newark carry an identical line on the settlement sheet: a 4 percent realty transfer tax, split evenly between buyer and seller, working out to $14,000 total and $7,000 on each side, as AmeriSave reports for New Castle County. That surprises people, because the closing-cost calculators and rate-comparison pages that surface first when you search for Delaware transfer tax by county routinely list Kent County at 3 percent or 3.5 percent, a full point or more below what New Castle County charges. For most real transactions in Kent County, that gap does not exist.
Why the calculators get Kent County wrong
Delaware's realty transfer tax has two moving parts: a state tax and a local tax collected by whatever county or municipality has jurisdiction over the parcel. Under Delaware Code Title 30, Section 5402, the state's default rate is 3 percent. It drops to 2.5 percent only when the local government has adopted the full 1.5 percent rate the state authorizes. Add the two together and the total lands at 4 percent whether the split is 2.5 and 1.5 or 3 and 1. That arithmetic is the whole story, and it's why the idea of Kent County as the cheaper option falls apart once you look at what Dover and the rest of the county actually charge.
Kent County Levy Court's own ordinance imposes a 1.5 percent transfer tax on property in the county's unincorporated areas, the same ceiling New Castle County uses. Dover's municipal code sets its rate at the identical 1.5 percent. In both cases the state share drops to 2.5 percent, and the combined bill comes to 4 percent.
A handful of small Kent County towns complicate the picture without changing the outcome. Delaware Mortgage Loans lists Hartly, Kenton, and Woodside as collecting only a 1 percent local tax instead of the full 1.5. Because that falls short of the threshold that triggers the state's reduction, the state rate stays at its default 3 percent in those towns. The two numbers still add to 4 percent.
| Where | Local rate | State rate | Combined |
|---|---|---|---|
| New Castle County (most municipalities) | 1.5% | 2.5% | 4% |
| Dover | 1.5% | 2.5% | 4% |
| Unincorporated Kent County | 1.5% | 2.5% | 4% |
| Hartly, Kenton, Woodside | 1.0% | 3.0% | 4% |
What 4 percent actually costs in Dover
Run those numbers against Kent County's own market and the size of the surprise gets easier to picture. Dover's median sold price sat at $290,000 as of March 2026, up 10.3 percent from a year earlier. At 4 percent, that's $11,600 in combined transfer tax, split into $5,800 on each side of the closing table. Asking prices have run higher since: the median list price in Dover was $379,000 as of September 2026. At the same 4 percent, a home closing anywhere near that figure carries $15,160 in transfer tax, or $7,580 per side. Neither number resembles the 3 percent scenario a rate calculator might have set someone up to expect.
There is one real discount available, and it has nothing to do with which county the property sits in. Delaware's first-time homebuyer exemption reduces the buyer's share of the state portion by 0.5 percent on the first $400,000 of a home's value, capped at $2,000 in savings. On a $290,000 purchase, that reduction is worth $1,450. A first-time buyer in Kent County pays less than a repeat buyer in Kent County. Neither one pays less than a comparable buyer in New Castle County for the same reason.
The real advantage Kent County buyers have right now
Kent County does hold a genuine advantage at the moment, and it shows up on the annual property tax bill rather than at the transfer tax line. Kent was the first of Delaware's three counties to complete the court-ordered reassessment that replaced valuations dating back to 1987. New bills went out for the 2024 tax year, and the county rolled its rate back to 5.72 cents per $100 of assessed value specifically to keep total collections flat rather than let the new, much higher valuations translate into a windfall.
New Castle County and Sussex County followed a year later, and New Castle's rollout has been rougher. Assessed values there rose by an average of 433 percent, prompting a special legislative session in August 2025 and a string of follow-up bills that have carried into the current legislative session, including one requiring New Castle's non-residential parcel corrections to be finished by October 16, 2026, as WDEL reported.
A buyer closing in Kent County today is stepping into a tax base that has already absorbed its adjustment and settled. A buyer closing in New Castle County right now is closing inside a process that is still being corrected in real time. Delaware's 2023 reassessment law requires each county to repeat the process every five years, which puts Kent's next reassessment around 2029. For anyone weighing the two counties side by side, that stability, not the transfer tax rate, is the actual difference worth factoring into the decision.
The septic inspection nobody mentions until it's scheduled
Transfer tax and property tax aren't the only Kent County line items that catch people off guard. Any property not connected to public sewer needs a Class H septic inspection before the sale can close, a requirement the Department of Natural Resources and Environmental Control enforces statewide and tracks through a searchable database of completed inspections. The inspection includes a required pumping of the tank, and providers that perform the work typically start pricing around $500.
Dover's incorporated core runs on public sewer, but plenty of the county's growing communities, Magnolia, Cheswold, Felton, and Viola among them, still run on private wells and septic systems, and further out toward Hartly, Kenton, and Frederica septic is close to universal. A buyer coming from a sewered market elsewhere in the tri-state area may not learn this step exists until an inspector is already scheduling the appointment.
Who actually pays, and when there's room to negotiate
Who writes the check for all of this is a matter of contract, not law. The Delaware Association of Realtors' standard practice splits the combined transfer tax evenly between buyer and seller, but the split is negotiable, and either side can ask for a different share as part of the offer. AmeriSave says Delaware also requires a licensed attorney at closing, adding another $750 to $1,250 to the transaction regardless of which side of the county line the property sits on.
None of that changes with the county. What changes is how much room a seller has to negotiate the split, and that room tends to shrink during the tightest weeks of the year. Kent County has a predictable crunch of its own: relocations tied to Dover Air Force Base cluster listings in neighborhoods like Rodney Village, Kent Acres, Capital Park, and Fox Hall into the same few weeks each summer, and a seller working against orders has less leverage to hold out for a favorable split than one listing in a quieter month.
Frequently asked questions
Is Kent County's transfer tax negotiable? The 4 percent total is set by state and local law. Who pays it is not. The standard 50/50 split can be adjusted in the purchase contract if both sides agree.
Does the first-time buyer exemption change the county comparison? No. It reduces the buyer's state-portion share by up to $2,000 in any Delaware county, so it makes a first purchase cheaper than a repeat one.
When is Kent County's next property reassessment? Kent's current values took effect for the 2024 tax year. Under the state's 2023 law requiring reassessment every five years, the next countywide reassessment is expected around 2029.
Do I need a septic inspection if my Kent County home is on public sewer? No. The Class H inspection requirement applies to properties served by private septic systems. Homes connected to Dover, Camden, or Smyrna's public sewer are not subject to it.
For anyone listing near Rodney Village this fall, the number to plan around at settlement is 4 percent, not whatever a generic calculator shows.
