The Best Resource for Inheriting Real Estate in Delaware and Settling the Tax Paperwork

For executors and beneficiaries inheriting real estate in Delaware, the right tool is a structured Delaware estate tax guide — not generic tax software, not a national estate planning article, and not the state's official websites alone. The reason is specific: Delaware's inherited real estate process involves three overlapping systems that each handle one piece of the puzzle without explaining how it connects to the others. The Register of Wills handles the probate inventory and title transfer. The Division of Revenue handles the tax affidavit. The county Recorder of Deeds handles the recorded deed. A title company refuses to close until all three are aligned — and none of the three government offices will explain the full workflow to you.

This article maps the complete process for clearing the title on inherited Delaware real estate, documenting the step-up in basis, and selling without triggering unnecessary capital gains.

Why Delaware Real Estate Inheritance Is Not Straightforward

Delaware repealed its state estate tax in 2018. No state tax is owed on inherited property. Executors who hear this often assume real estate is simple: transfer the deed, the beneficiary inherits, done.

In practice, three requirements stand between an inherited Delaware property and a cleared, marketable title:

1. The "No Estate Tax" Affidavit. Despite the repeal, the Register of Wills requires a sworn "Affidavit of No Delaware Estate Tax" to confirm that no state tax lien exists on the property. Title companies universally require proof that this affidavit has been filed and accepted before they will close a sale. The filing costs $10 and must be submitted to the Register of Wills in the county where the property is located. Many executors do not discover this requirement until they are already under contract with a buyer — at which point the delay can cause the buyer to walk.

2. The Inventory as Title Transfer. The Delaware Register of Wills does not just administer probate fees. The Inventory filing (Form 600W), which must be submitted within exactly three months of the granting of Letters Testamentary, functions as the legal equivalent of a deed transfer for real property in the estate. The names and relationships of the new owners listed on the Inventory schedule officially pass title in the county records. If the Inventory is filed incorrectly or incompletely, the title transfer is invalid.

3. Step-Up in Basis Documentation. Before the estate sells the property — or before beneficiaries decide to keep it — the executor must document the date-of-death fair market value of the real estate. This value becomes the beneficiary's cost basis under federal tax code section 1014. Getting this documentation right is the difference between owing capital gains on years of appreciation and owing nothing.

The Step-Up in Basis: Why It Matters More Than the Estate Tax

Delaware has no state estate tax. The federal estate tax exemption is $15,000,000 per individual for deaths in 2026. The overwhelming majority of Delaware estates owe no estate tax at any level.

What matters financially for most beneficiaries is the step-up in basis — and most executors do not understand it until they are about to sell the property.

Here is how it works. The decedent originally purchased the property for, say, $80,000. At the time of death, the property is worth $380,000. Under the step-up in basis rule, the beneficiary's cost basis for tax purposes is reset to $380,000 — the fair market value on the date of death. If the beneficiary sells the property for $380,000, the capital gain is $0. If the decedent had lived and sold at $380,000, the gain would have been $300,000, subject to capital gains tax.

The step-up in basis effectively eliminates decades of accrued capital gains for the beneficiary. For Delaware families with long-held real estate in areas of significant appreciation — particularly coastal Sussex County, which has seen substantial property value growth — this can represent tax savings of tens of thousands of dollars on a single transaction.

What the executor must do to preserve this benefit:

• Order a qualified appraisal of the property as of the date of death (not the date of sale, not the county assessed value)
• Record this value on the estate Inventory (Form 600W) filed with the Register of Wills
• Ensure the appraised value matches what is used on any federal estate tax return filed (even a portability-only Form 706)
• Retain the appraisal permanently — beneficiaries will need it as the basis documentation when they eventually sell

If the executor skips the formal appraisal and uses the county tax assessment instead, beneficiaries may face IRS challenges to the stepped-up basis when they sell. The county assessed value in Delaware has historically diverged significantly from fair market value, particularly in counties that have not reassessed recently.

Selling an Inherited Delaware Property: The Full Sequence

Note that the property sale proceeds may be included in the estate's taxable income if sold after the date of death. If the sale price exceeds the stepped-up basis — which happens when the property appreciates between the date of death and the date of sale — the gain is subject to capital gains tax and must be reported on Form FID-TAX.

Who This Applies To

This guide is specifically relevant to you if:

• You are the executor of a Delaware estate that includes residential real estate, and you need to clear the title before selling or transferring the property
• You are a beneficiary who has inherited a Delaware property and want to understand your capital gains exposure before deciding whether to sell, rent, or keep it
• You discovered the "No Estate Tax Affidavit" requirement during a title search and do not know how to complete it or how long it takes
• You are managing the estate of a parent or spouse who owned property in Delaware for many years and want to ensure the stepped-up basis is properly documented before the property is sold
• You are handling the estate yourself without an attorney and need to understand how the Register of Wills inventory connects to the real estate title transfer

Who This Is Not For

• Estates where real estate is held in a living trust — trust assets generally bypass the Register of Wills entirely, and the trust's successor trustee controls the transfer
• Properties covered by a Transfer-on-Death deed recorded during the decedent's lifetime — TOD deed beneficiaries typically receive property outside of probate, though they still need to document the stepped-up basis
• Estates where the real estate is located outside Delaware — the process for out-of-state properties requires ancillary probate in the state where the property is located

County-Specific Differences That Affect Real Estate Transfers

Delaware's three counties handle the real estate transfer process differently in ways that affect both cost and procedure.

New Castle County charges a 1.75% closing fee plus a 0.25% technology surcharge (totaling 2.00%) on the net personal estate. If the will directs that real estate be sold as part of estate administration, the proceeds become part of the probate estate and the closing fee applies to them. The county also allows pro se executors to use the Affidavit in Lieu of Receipts for estates with deductions under $100,000.

Kent County charges a 1.75% closing fee with no technology surcharge. The Affidavit in Lieu of Receipts is labeled "For Attorneys Only" — pro se executors in Kent County must submit physical receipts for all claimed deductions.

Sussex County charges the lowest closing fee at 1.25% but enforces the same "For Attorneys Only" restriction on the Affidavit in Lieu of Receipts as Kent County. Deed recording fees also differ: Kent County charges a $36 document fee plus $10 per page; Sussex County charges a $30 surcharge plus $9 per page.

For a $400,000 real estate sale included in a Delaware probate estate, the difference between New Castle County's 2.00% closing fee and Sussex County's 1.25% fee is $3,000. This is real money, and it is entirely county-dependent.

Common Mistakes to Avoid

Waiting until a sale is pending to file the NETA. The No Estate Tax Affidavit must be processed by the Register of Wills before the title company can close. File it as soon as the estate is opened, not after you have a buyer.

Using the county tax assessment as the basis instead of a formal appraisal. Delaware counties have historically had significant divergence between assessed values and fair market values. The IRS expects a qualified appraisal, not an assessor's figure, as documentation for the stepped-up basis.

Distributing real estate before the eight-month creditor period expires. Delaware law prohibits asset distribution during the eight-month creditor window. If the estate sells real estate and distributes the proceeds before this window closes, the executor faces personal liability if a valid creditor claim surfaces later.

Forgetting the Transfer-on-Death deed trap. Delaware law allows vehicle owners and, more recently under House Bill 147, real estate owners to designate Transfer-on-Death beneficiaries. However, a TOD designation for real estate must be properly recorded with the county Recorder of Deeds during the owner's lifetime. Unrecorded TOD documents discovered after death are not enforceable, and the property falls back into the probate estate.

Tradeoffs

Managing Delaware real estate inheritance yourself saves professional fees and keeps you in control. The risk is that procedural errors — a late Inventory, a missed NETA filing, an undocumented basis — create delays that cost far more than the professional fees you avoided. The title clearance step in particular has no shortcut: it requires the right form, filed with the right county office, processed before closing. There is no way to retroactively clear a title after a sale falls through.

For complex estates — multiple properties, out-of-state real estate, properties with title complications, or properties held in entities — consulting a Delaware estate attorney is worth the cost. For a single primary residence transferring to direct beneficiaries in a straightforward estate, the process is manageable with the right guidance.

FAQ

Does Delaware have an inheritance tax on real estate?

No. Delaware has neither a state estate tax nor a state inheritance tax. Beneficiaries who inherit Delaware real estate do not owe any state tax on the inheritance itself. They may owe capital gains tax if they later sell the property at a price above the stepped-up basis, but the step-up typically eliminates most or all of that liability if the property is sold soon after inheritance.

What is the No Estate Tax Affidavit and why is it required?

The "Affidavit of No Delaware Estate Tax" (NETA) is a sworn document filed with the county Register of Wills confirming that no state estate tax lien exists on the property. Although Delaware repealed its estate tax in 2018, the procedural requirement to affirmatively clear tax liens was not removed. Title companies require proof of this filing before closing any sale of inherited real estate. Without it, the title is considered encumbered.

How long does it take to get the No Estate Tax Affidavit processed?

Processing times vary by county and current caseload at the Register of Wills office. In general, allow several weeks from filing to receiving confirmation. This is why filing the NETA as soon as the estate is opened — rather than waiting until a sale is imminent — avoids delays during what is typically the most time-pressured phase of estate administration.

What appraisal do I need to document the step-up in basis for Delaware real estate?

You need a qualified appraisal from a licensed real estate appraiser, valued as of the date of death. The IRS standard is that the appraisal must be conducted by a qualified appraiser and must reflect the property's fair market value on the valuation date. County tax assessments do not meet this standard and should not be used as the basis for step-up documentation.

Does the probate closing fee apply to real estate in Delaware?

It depends on whether the real estate is included in the probate estate and sold pursuant to the will. If the will directs the executor to sell real estate and distribute the proceeds, the sale proceeds become part of the net personal estate and the Register of Wills closing fee applies. If real estate passes directly to a named beneficiary by bequest in the will — without being sold — it is typically excluded from the closing fee calculation. The specific handling differs somewhat by county.

The Delaware Final Tax & Estate Tax Guide covers the complete real estate inheritance workflow: the NETA affidavit filing, the step-up in basis documentation, the county-specific Inventory requirements, and the closing fee calculation for each county. It also includes a $1,000,000 fiduciary threshold diagnostic and a full timeline tracker organized by statutory deadlines.
