Delaware Realty Transfer Tax: Rates, Exemptions, and Who Pays

The Delaware realty transfer tax is a combined state and local charge that reaches 4% of a property’s value on most sales and transfers of real estate in the state. The state takes 3% and local governments can add up to 1.5%; when a locality imposes the full 1.5%, the state rate drops to 2.5%, so the total lands at 4%.¹ Buyer and seller customarily split the bill 50/50 at closing, though the allocation is negotiable, and the tax must be paid before the county recorder will accept the deed.

How the Tax Is Calculated

The base is the total consideration for the property. That includes cash paid plus the value of any mortgages assumed, liens taken subject to, and other financial obligations passing to the buyer. Where no cash changes hands, such as a property exchange or a corporate merger, fair market value is used instead. Delaware tax authorities can reassess the reported value if it looks artificially low, particularly in transfers between related parties.

Most Delaware jurisdictions levy the full 1.5% local rate, so the effective combined rate on nearly all transactions is 4%.¹ In the rare locality with a local rate below 1%, the state still collects its full 3%, and the total may come in below 4%.²

A worked example: on a $300,000 home in a jurisdiction with the standard 4% combined rate, the total transfer tax is $12,000. At the customary even split, buyer and seller each pay $6,000.¹

Transfers valued below $100 are exempt entirely, and the tax return itself calculates the liability on the greater of the consideration paid or the property’s highest assessed value.³

First-Time Homebuyer Reduction

If you have never held a direct legal interest in residential real estate anywhere, and you plan to occupy the property as your principal residence within 90 days, you qualify for a 0.5% reduction on your share of the tax. The reduction applies to the lesser of the property’s value or $400,000, capping the savings at $2,000.⁴

On the $300,000 home above, a qualifying first-time buyer’s share drops from $6,000 to $4,500. The reduction touches only the buyer’s half; the seller still owes the full seller’s portion.³

A few conditions catch buyers off guard. Spouses or co-buyers only qualify if neither person has ever owned residential real estate; one prior owner disqualifies the whole purchase. For new construction, the 90-day occupancy clock starts when the certificate of occupancy is issued, not when the deed is recorded.³

Exemptions

Delaware carves several categories of transfer out of the tax entirely by removing them from the statutory definition of a taxable document. If your transaction fits one of these, no tax is owed at all.

Family Transfers

Conveyances between close family members are exempt whether or not money changes hands. Qualifying relationships include 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 party owes transfer tax. The grandparent-grandchild exemption was added by legislation effective in late 2025.⁶

Entity and Reorganization Transfers

Transfers between a parent entity and its wholly-owned subsidiary are exempt when no actual consideration changes hands. Mergers and other reorganizations where the same beneficial owners retain at least 80% of the interest in the real estate also avoid the tax; once ownership shifts push below that 80% line, the Secretary of Finance may treat the deal as a taxable sale.⁵

Other Categorical Exemptions

Conveyances to organizations exempt under IRC Section 501(c)(3) are excluded when made without consideration.
Correctional deeds fixing errors in earlier conveyances are exempt when no additional consideration is paid.
Transfers to or from a trustee, nominee, or straw party for the same beneficial owner are not taxable, since no real change in ownership occurs.
Sales of mobile homes are exempt from the realty transfer tax, though a separate document fee applies.¹

One boundary worth noting: certain long-term residential leases (those running longer than five years, counting renewal options as exercised) are treated as taxable transfers. A short residential lease does not trigger the tax.⁵

Who Pays and When

Delaware law makes every person who makes, delivers, accepts, or presents a document for recording liable for the tax.² That statutory language sweeps in both buyer and seller. The 50/50 split is custom, not law, and parties can allocate the burden however they choose. What the state cares about is that the full amount is paid before recording. If one side defaults on its share, the other remains on the hook.

Payment moves through the closing. The settlement agent, title company, or attorney collects the tax and delivers it to the recorder’s office. No deed can be recorded without documentary stamps showing the tax has been paid.³ Mortgage lenders verify payment before releasing loan funds, so an unresolved transfer tax dispute can stall or kill a closing.

In foreclosure sales, the tax is still due, and it typically falls on the winning bidder unless the sale terms say otherwise.

Overpayments and Refunds

Overpayments happen — usually from clerical errors on the return or a miscalculation of the taxable 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 the return was due or two years from the date the tax was actually paid; if no return was filed, the window is two years from payment.⁷

Penalties for Nonpayment

Delaware enforces the tax through both civil and criminal penalties. The civil penalty for late payment is 1% of the unpaid tax for the first month, plus another 1% for each additional month the balance remains outstanding, capped at 25%. Unpaid amounts also accrue interest at 0.5% per month, compounding monthly.⁸ A $12,000 tax bill left unpaid for a year picks up roughly $1,440 in penalties on top of the compounding interest.

Misrepresenting the sale price or otherwise evading the tax is a criminal offense. Every document presented for recording must state the true, full, and complete value of the transaction, or arrive with an affidavit doing so.⁹ Violating that requirement carries a fine of up to $500 and up to one year in jail.¹⁰

Beyond penalties, unpaid transfer tax clouds title. The deed cannot be recorded, lenders will not finance a property with the balance outstanding, and the state can pursue collection against either party to the transaction.

Documents Required at Closing

The deed itself must be signed, notarized, and comply with Delaware property law. It travels to the county recorder alongside a Realty Transfer Tax Return (Form RTT-TAX, formerly Form 5402), which reports the property’s location, the date of conveyance, and the consideration paid. The form calculates tax on the greater of the consideration or the property’s highest assessed value.¹¹

Claiming an exemption requires supporting paperwork attached 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. Deals involving mortgage assumptions typically need a settlement statement such as an ALTA Closing Disclosure showing the outstanding balance, and estate transfers may require a probate certificate or court order. Missing attachments delay recording, and in some cases result in denial of the exemption.¹¹
