Delaware charges no state or local sales tax, so the materials that go into a home — lumber, roofing, windows, cabinetry, fixtures and finishes — are not taxed at the register the way they are in neighboring states, where sales tax sits around 6%. On a material-heavy custom home, that difference adds up to real savings, one of several reasons the coast draws builders and buyers alike.
It is one of the most quietly compelling reasons to build on the Delaware coast rather than across the line in Maryland or Pennsylvania. But the full picture has a nuance worth understanding, and this article lays it out honestly — what the no-sales-tax advantage actually means for a build, how Delaware compares to the states its buyers come from, and where the savings are real versus where they need context.
A note first: this is general information, not tax advice. Confirm how any of it applies to your project with a licensed tax professional.
Delaware’s No-Sales-Tax Advantage, Explained
Delaware is one of only five states in the country with no sales tax, and unlike some of them, it does not allow cities or counties to add a local sales tax either. The rate is simply zero, statewide, with no exceptions layered on at the town level.
For everyday shopping that is a nice perk. For a project as material-intensive as building a home, it becomes something more significant. Every appliance, every window, every yard of tile and every board foot of lumber that would carry a sales tax elsewhere carries none here. Working with a Delaware custom home builder means those purchases happen inside a no-sales-tax state.
What That Means for Building Materials
Materials make up a substantial share of what goes into a custom home — the structure, the envelope, the systems and the finishes all represent goods that have to be purchased. In a state with sales tax, that share is taxed. In Delaware, it is not.
The savings are not a gimmick or a limited-time promotion; they are structural, built into where the home is located. And because a luxury coastal home tends to carry higher-end materials and finishes, the untaxed portion is larger in absolute terms than it would be on a modest build. The more the home invests in quality materials, the more the no-sales-tax advantage matters.
How Delaware Compares to Neighboring States
Most of the buyers building on the Delaware coast come from the surrounding mid-Atlantic states, and the contrast is stark. Maryland and Pennsylvania both apply a statewide sales tax of roughly 6%. New Jersey sits a bit higher, in the mid-6% range. New York layers a state rate on top of local rates that together often approach or exceed that level, and the District of Columbia sits around 6% as well.
Build the same home in one of those jurisdictions and the materials are taxed on the way in. Build it on the Delaware coast and they are not. For a family coming from Baltimore, Philadelphia, New York or Washington, that is a genuine difference in the math of building — not a marketing angle, but a feature of the state itself.
The Honest Nuance: Delaware’s Gross Receipts Tax
Here is the part that gets left out of the simple “no sales tax” headline. Delaware funds itself differently: instead of a sales tax, it levies a gross receipts tax on businesses, and contractors pay it on the work and materials supplied for real property in the state.
The key point for a homeowner is scale. The construction gross receipts tax is a small fraction of one percent — far below a 6% sales tax — and it comes with meaningful exemptions, including an exclusion on the first portion of gross receipts each month and a deduction for payments made to licensed subcontractors. It is a cost of doing business that a licensed Delaware builder already handles, not a line item that erases the materials advantage. The net effect still favors building in Delaware, but an honest comparison names both sides.
Why Materials Weigh So Heavily on a Custom Home
A custom home is, in large part, an assembly of purchased goods. The framing package, the roofing, the windows and doors, the cabinetry, the flooring, the plumbing and lighting fixtures, the appliances and the millwork are all materials — and on a quality coastal home, they are materials chosen for durability and craftsmanship.
That is why the tax treatment of materials matters more on a home than on almost any other purchase. You can see the level of material investment across our completed custom homes, where the finishes and systems represent a large, untaxed share of the build. The same logic applies to a substantial home remodeling project, which is often just as material-intensive as new construction.

Beyond Sales Tax: Delaware’s Broader Appeal
The no-sales-tax structure rarely stands alone in a buyer’s decision. Delaware is widely regarded as a tax-friendly state for homeowners overall, which is part of why so many out-of-state families choose to build and eventually retire here rather than in the states they came from.
Add the drive-to convenience of the coast, the quality of the beach communities, and a setting built for the way people want to live near the water, and the tax advantage becomes one attractive piece of a larger picture. Exploring where we build across coastal Sussex County shows how the lifestyle and the practical advantages line up, and reviewing available land in Delaware is a natural next step for anyone weighing a build here. As always, confirm the specifics of your own situation with a tax professional.
Putting the Savings in Perspective
It would be easy to throw out a big number here, but an honest builder will not, because the real figure depends entirely on your home — its size, its finishes, and how much of the cost goes to taxable materials versus labor. What can be said with confidence is that the saving scales with the materials: the more a home invests in quality goods, the larger the untaxed portion.
For a luxury coastal home with premium finishes, avoiding roughly 6% of sales tax on the material share is not trivial. It is one more reason the numbers tend to favor building in Delaware — and one you should confirm against your own plan with a professional who can run your specific figures.
Build With a Licensed Delaware Team
Capturing the advantage cleanly means building with a licensed Delaware contractor who understands the state’s tax structure and handles the gross receipts tax as a normal part of doing business. That is simply how a professional coastal builder operates here.

Delaware No-Sales-Tax FAQ
Does Delaware really have no sales tax?
+
Yes. Delaware is one of only five U.S. states with no sales tax, and it does not allow cities or counties to add a local sales tax either. The rate is zero statewide. For a purchase as material-intensive as building a home, that means the goods that go into the house are not taxed at the register the way they would be in most other states.
How does no sales tax lower the cost of building a home?
+
Building materials — lumber, roofing, windows, cabinetry, fixtures and finishes — make up a large share of a home. In states with sales tax, that share is taxed at roughly 6% or more. In Delaware it is not, so the material portion of the build avoids that tax. The savings scale with how much a home invests in quality materials.
How does Delaware compare to Maryland, Pennsylvania and New Jersey?
+
Maryland and Pennsylvania both apply a statewide sales tax of about 6%, and New Jersey sits in the mid-6% range. New York combines a state rate with local rates that often approach 8%, and Washington, D.C. is around 6%. Delaware’s rate is zero, so materials that would be taxed in those places are not taxed here.
Does Delaware have a gross receipts tax instead?
+
Yes, and it is important to be honest about it. Instead of a sales tax, Delaware levies a gross receipts tax on businesses, and contractors pay it on work and materials for real property. It is a small fraction of one percent — far below a 6% sales tax — and comes with exemptions, so the net comparison still favors building in Delaware.
Do I pay sales tax on appliances and finishes for a Delaware home?
+
Purchases made in Delaware are not subject to sales tax, including the appliances, fixtures and finishes that go into a home built here. This is one reason the no-sales-tax advantage is especially meaningful on a higher-end coastal home, where premium materials and appliances represent a significant, untaxed share of the build.
How much will I actually save by building in Delaware?
+
It depends entirely on your home — its size, finishes, and how much of the cost goes to taxable materials versus labor. An honest builder will not quote a blanket figure. What is certain is that the saving scales with the materials, so a home with premium finishes benefits more. Ask a tax professional to run your specific numbers.
Is Delaware a tax-friendly state for homeowners overall?
+
Delaware is widely regarded as a tax-friendly state for homeowners, which is part of why many out-of-state families choose to build and retire here. The absence of sales tax is one element of that reputation. Because individual circumstances vary, confirm how Delaware’s tax structure applies to you with a licensed tax professional.
Do I need a Delaware-licensed builder to benefit?
+
Building with a licensed Delaware contractor is the clean way to do it. A professional coastal builder understands the state’s tax structure and handles the gross receipts tax as a normal part of the job, so you capture the materials advantage without complication. It is simply how building works in Delaware.
Build Where the Numbers Work in Your Favor
The no-sales-tax advantage is not the only reason to build on the Delaware coast, but it is a real one, grounded in how the state is structured rather than in any promotion. For a material-intensive custom home, not paying sales tax on the goods that go into it is a meaningful, lasting benefit — one that scales with the quality you build in. It is one more reason a custom home on the Rehoboth Beach coast makes sense for families coming from higher-tax states.
