Delaware Realty Transfer Tax: Rates, Exemptions, and Penalties

The Delaware realty transfer tax is a combined state and local tax of up to 4% of a property’s value, imposed on nearly every deed recorded in the state. Buyers and sellers customarily split the bill evenly at closing, though the allocation is negotiable. The tax has to be paid before the county recorder will accept the deed, which makes it one of the largest and most time-sensitive line items in any Delaware real estate closing.¹

How Much You’ll Owe

The state imposes a base rate of 3%. Counties and municipalities may add up to 1.5% on top. When a locality charges the full 1.5%, the state rate drops to 2.5%, producing the familiar 4% combined rate. Most Delaware jurisdictions impose the full local rate, so 4% is what you should expect to see on your closing statement. In the rare locality with a local rate below 1%, the state collects its full 3% and the combined rate comes in lower.²

The tax is calculated on the total consideration for the property. That includes cash paid, the value of any assumed mortgages or liens, and other financial obligations the buyer takes on. For a property exchange or a corporate merger where no cash moves, the tax is based on fair market value. The state can reassess a reported value that looks artificially low, especially in transfers between related parties.

A quick example: on a $300,000 home in a jurisdiction with the standard 4% rate, the total transfer tax is $12,000. With the typical even split, each side pays $6,000.¹ Transfers valued below $100 are exempt entirely.³

Who Pays and When

Delaware law reaches every person who makes, delivers, accepts, or presents a document for recording, so both the buyer and seller are legally liable.² The 50/50 split is custom, not a legal requirement. Parties can agree to any allocation in the purchase contract. What the state cares about is that the full amount reaches the recorder; if one side defaults, the other remains on the hook.

The settlement agent, title company, or attorney running the closing collects the tax and remits it. The recorder will not accept the deed without proof that the tax has been paid.³ Mortgage lenders usually confirm payment before releasing loan funds, so an unresolved transfer tax issue can stall or kill a closing. In foreclosure sales, the tax is still owed and typically falls on the winning bidder unless the sale terms say otherwise.

First-Time Homebuyer Reduction

If you have never held a direct legal interest in residential real estate anywhere, and you intend to use the property as your principal residence within 90 days, you qualify for a 0.5% reduction on your share of the transfer tax. The reduction applies to the lesser of the property’s value or $400,000, which caps the maximum savings at $2,000.⁴ On that same $300,000 home at 4%, a qualifying first-time buyer’s share drops from $6,000 to $4,500. The reduction only touches the buyer’s share. The seller’s half is unchanged.³

Co-buyers qualify only if neither person has ever owned residential real estate. If one spouse previously owned a home, the whole purchase loses the reduction. For new construction, the 90-day occupancy clock starts when the certificate of occupancy is issued, not when the deed is recorded.³

Transfers That Are Exempt

Delaware exempts a defined set of transfers by writing them out of the definition of a taxable document. These are categorical exemptions, so a qualifying transfer owes nothing, not a reduced amount.

Family Transfers

Transfers between close family members are exempt regardless of whether money changes hands. The exemption covers spouses, former spouses (for property acquired before the divorce decree), parents and children (including a child’s spouse), grandparents and grandchildren (including a grandchild’s spouse), and siblings, half-siblings, and step-siblings.⁵ A parent can sell a house to a child at full market value and neither side owes transfer tax. The grandparent-grandchild exemption was added by recent legislation effective in late 2025.⁶

Other Exempt Transfers

Conveyances to a parent entity’s wholly-owned subsidiary (or vice versa) when no actual consideration changes hands.
Mergers and reorganizations where the same beneficial owners retain at least 80% of the interest in the real estate.
Conveyances to organizations exempt under IRC Section 501(c)(3), when made without consideration.
Correctional deeds that fix errors in earlier conveyances, when no additional consideration is paid.
Transfers to or from a trustee, nominee, or straw party for the same beneficial owner.
Sales of mobile homes, which carry a separate document fee instead.¹

Situations That Still Trigger the Tax

A few transactions catch people off guard because they don’t involve a straightforward deed.

Long-term leases. Not every lease is taxable, but assignments or transfers of possessory interests in residential property or condominium units under leases running longer than five years do trigger the tax. Renewal and extension options count toward that threshold, so a three-year lease with a three-year renewal option is treated as a six-year lease.⁵

Entity transfers. Selling the LLC or corporation that owns the property, rather than deeding the property itself, does not avoid the tax. When beneficial ownership changes through transfers of stock, LLC membership interests, partnership interests, mergers, or similar transactions, the transfer is taxable as though the property were conveyed by deed. The threshold is 80%: if the original beneficial owners retain at least 80% of the interest after the transaction, no tax applies. Once that stake drops below 80%, the Secretary of Finance may treat the transfer as a taxable sale, weighing timing, business purpose, and beneficial ownership before and after.⁵ Transfers of publicly traded stock and bona fide pledges of ownership interests as loan collateral fall outside this rule.

Quick flips of improved land. If you buy land, build improvements worth more than $10,000, and sell within one year, an additional tax applies to the value of those improvements above the $10,000 threshold. This is on top of the standard transfer tax on the underlying property value.¹

Penalties for Nonpayment

Late payment carries a civil penalty of 1% of the unpaid tax for the first month and an additional 1% for each month afterward, capped at 25%. Unpaid balances also accrue interest at 0.5% per month, compounding monthly.⁷ A $12,000 bill left unpaid for a year picks up roughly $1,440 in penalties plus compounding interest.

Deliberately misrepresenting the sale price is a criminal offense. Every document presented for recording must state the true, full, and complete value of the transaction, or come with an affidavit that does.⁸ A violation can bring a fine of up to $500 and up to one year in jail.⁹

Beyond penalties, an unpaid transfer tax clouds the title. The deed cannot be recorded, lenders will not finance the property while the obligation sits open, and the state can pursue both parties to the transaction.

Documents You’ll Need at Closing

The deed must be signed, notarized, and compliant with Delaware property law. Along with the deed, the parties file a Realty Transfer Tax Return (Form RTT-TAX, formerly Form 5402), reporting the property’s location, the date of conveyance, and the consideration paid. The form asks for both the consideration and the property’s highest assessed value, and the tax is calculated on whichever is greater.¹⁰

If you’re claiming an exemption, attach supporting documentation to the return. Family transfers need an affidavit establishing the qualifying relationship. Trustee or nominee transfers need a copy of the original conveyance to that trustee. Transactions involving mortgage assumptions typically require a settlement statement such as an ALTA Closing Disclosure showing the outstanding balance. Estate transfers may need a probate certificate or court order. Missing attachments delay recording and can result in the exemption being denied.¹⁰

If You Overpay

Overpayments happen, usually from clerical errors on the return or miscalculated consideration. You can file a claim for credit or refund with the Division of Revenue. The deadline is the later of three years from the date prescribed for filing the return or two years from the date the tax was actually paid. If no return was filed, the window shortens to two years from payment.¹¹ Review your closing documents soon after signing; the sooner you spot a problem, the more room you have to fix it.
