Introduction to Taxes on New Construction Homes

Purchasing or building a new construction home is complex, with a unique blend of excitement and intricacies—especially when it comes to taxes. While the dream of owning a brand-new home comes with the promise of fewer repairs and up-to-date amenities, the maze of taxes associated with new builds can catch even the savviest buyers off-guard.

Understanding the taxes involved is essential for budgeting, financing, and ultimately enjoying the homeownership experience. These taxes are not just limited to annual property taxes but span several layers of federal, state, and local taxation, potentially adding tens of thousands of dollars to your initial and ongoing costs. Let’s break down the primary kinds of taxes involved and what you can expect at different stages of the new construction process.

Understanding Property Taxes on New Construction

Property taxes are one of the biggest annual expenses for any homeowner, including those who own newly constructed properties. These taxes fund essential local government services like schools, police, fire departments, and infrastructure. The way property taxes are calculated and applied to new construction homes, however, can differ significantly from existing homes.

Basics of Property Taxes

Property tax is a local tax calculated as a percentage of your property’s assessed value. The actual amount you pay is determined by the property’s value, the local tax rate, and sometimes additional special assessments. In general, property taxes are:

• Determined by county or municipal assessors
• Levied annually, but paid semi-annually or quarterly in many states
• Subject to changes based on property reassessments, tax rate adjustments, and local referenda

How New Construction Differs

For new construction homes, property taxes present distinct challenges and opportunities:

1. Partial Assessment During Construction: While your home is incomplete, your property may only be assessed (and taxed) on the land value plus any partially completed structure. This typically results in lower initial bills.
2. Full Assessment Takes Effect Post-Completion: Once the home is finished and given a certificate of occupancy, the county will perform a full assessment, usually in the following tax year. The property tax bill can then rise sharply, so owners must be prepared for this adjustment.
3. Supplemental Tax Bills: In some jurisdictions, you may receive a supplemental tax bill that covers the difference in tax based on the new assessed value after completion and occupancy.

Example Scenario

Suppose you purchase a lot in January for $100,000 and begin construction, which completes the following August. Your first property tax bill might only reflect the land value. After the county reassesses to include your completed $400,000 home, your tax bill will increase accordingly, often resulting in a supplemental bill to cover the difference retroactively.

The Property Tax Assessment Process for New Builds

Knowing how your new home’s property value is assessed helps demystify where your tax bill comes from. The assessment process differs by location, but there are common elements to understand.

The Assessment Timeline

• Pre-Construction Assessment: Typically based on vacant land value.
• During Construction: Some jurisdictions add value incrementally as construction progresses, which may prompt partial assessments.
• Post-Completion: After your home passes final inspection and is eligible for occupancy, it is reassessed, often triggering the full property tax assessment for the improved property.

How Assessments Are Calculated

Assessed value uses market data, construction costs, and land value. Municipal or county assessors will usually consider:

• Value of the land prior to development
• Current construction status and quality
• Comparable new construction sales in the area
• Replacement cost of the new home minus depreciation (which is negligible for a brand-new home)
• Special features such as pools, garages, high-end finishes, or energy-efficient systems

Appealing an Assessment

If you believe your newly constructed home is assessed for tax purposes at a value that is too high compared to similar homes, you typically have the right to appeal. This involves submitting market comps, builder invoices, or evidence of defects that could impact the value.

Assessment Caps and Protections

Some states grant protection to homeowners via assessment caps or limits on how much the property’s taxable value can rise each year. For example, California’s Proposition 13 caps increases at 2% annually unless there’s a change in ownership or new construction.

Property Tax Exemptions and Abatements for New Construction

To stimulate housing supply and revitalization, many municipalities offer property tax abatements or exemptions for new construction homes. These programs can significantly reduce your tax burden for a specified period.

What Are Property Tax Abatements?

Abatements temporarily reduce or eliminate property taxes on new homes. Typically offered by cities or counties to spur development in certain neighborhoods or to encourage higher-density housing, these abatements can last from a few years to 10, 15, or even 20 years in some areas.

Common Types of Exemptions and Abatements

• Full Abatement: No property taxes due for a set period on improvements (not land), with taxes resuming gradually.
• Partial Abatement: Reduced property taxes on the value added by new construction.
• Targeted Exemptions: For historic renovation, energy-efficient construction, or revitalization projects.
• First-Time Homebuyer Exemptions: Some states offer breaks to first-time buyers purchasing or building a new home.

How to Qualify

Eligibility rules vary, but generally require homeowners to:

• Live in the property as a primary residence
• File an application with the county or city tax assessor’s office
• Complete construction and meet program deadlines
• Meet income or price caps set by the program

Examples of Abatement Programs

• New York City: The 421-a tax exemption program offers phase-in abatements for new residential construction.
• Philadelphia, PA: Offers a 10-year tax abatement for new construction and major improvements.
• Texas: Some cities provide partial exemptions for new homes built in designated improvement zones.

Warning: Watch the Expiration Date!

It’s vital to know when your abatement expires. Many homeowners face “sticker shock” when their property tax bill jumps dramatically as the abatement phases out. Plan for this adjustment in your long-term budget.

Sales Tax and Use Tax on Construction Materials and Services

Sales tax is generally thought of as something you pay at the store, but it also applies to the construction of new homes—mainly through materials and services used in building the home.

Who Pays the Tax?

• Production Builders: Typically, the builder pays sales tax when purchasing building materials. The customer pays the builder an all-inclusive price, and the builder remits the appropriate taxes to the state.
• Custom Builds: If you act as your own contractor or hire sub-contractors separately, you may be responsible for ensuring sales or use tax is properly paid on materials purchased directly.

Taxable Items and Services

• Lumber, concrete, tile, roofing, and finish materials
• Cabinetry, appliances (unless classified as fixtures), flooring
• Subcontractor labor (in some states)

Are New Homes Subject to Sales Tax?

Most states do not levy sales tax on the final, completed sale of a new home itself—the sales tax is built into the cost through construction expenses. However, some states or cities may charge sales tax on contractor labor, particularly on improvements to non-owner-occupied or investment properties.

Use Tax on Out-of-State Purchases

If contractors or owners buy materials out of state and bring them into the state for construction, use tax—functionally similar to sales tax—may be owed. States actively enforce this via audits and cross-checks.

Exemptions for Affordable or Energy-Efficient Construction

Some states exempt renewable energy equipment, affordable housing projects, or modular/pre-fabricated home materials from sales tax to promote sustainable, accessible housing.

Real Estate Transfer Taxes and Recording Fees

When you purchase a newly built home, you’ll likely encounter real estate transfer taxes and various recording fees. These closing costs can add up, especially in high-tax states.

What is a Transfer Tax?

A transfer tax, sometimes called a deed or real property transfer tax, is levied by states, counties, or municipalities on the transfer of title to real property. Rates and rules vary widely:

• State Level: Many states, including New York, Maryland, and Florida, impose state-level transfer taxes.
• County/City Level: Additional layers are imposed in cities like Philadelphia, New York City, and San Francisco.
• No Transfer Tax States: A handful of states have no transfer tax, including Idaho and Indiana.

How is the Tax Calculated?

Generally, transfer taxes are calculated as a percentage of the property’s sales price or as a fee per $1,000 of value. For example:

• A state might charge $3.50 per $1,000 of home value.
• City or county taxes add to this, sometimes doubling the total.

Who Pays the Transfer Tax?

Responsibility is negotiated during the transaction; in some states the buyer pays, in others, the seller or a split is common. Builders often clearly state in new construction contracts which party is responsible.

Recording Fees and Documentary Stamps

Additional small fees apply for recording the deed, mortgage documents, and other official paperwork. Some states, like Florida, charge “documentary stamp taxes” on mortgages as well as deeds.

Federal Tax Considerations for New Homeowners

On the federal level, several tax deductions, credits, and rules come into play when you purchase a new construction home. These can reduce your tax bill if you plan and file correctly.

Mortgage Interest Deduction

If you finance your new home with a mortgage, the interest paid on up to $750,000 in acquisition debt (for homes purchased after 2017) is deductible on your federal return if you itemize. For loans prior to 2018, the limit is $1 million.

Property Tax Deduction

As a homeowner, you can deduct up to $10,000 ($5,000 if married filing separately) in combined state and local property taxes, along with income or sales taxes, due to the SALT cap enacted by the Tax Cuts and Jobs Act.

Points and Origination Fees

If you pay mortgage points (prepaid interest), these are generally deductible as well—either immediately (for purchases) or over the life of the loan (for refinancing).

Energy Credits for New Construction

Special federal credits exist for new homes that meet energy efficiency standards—see the section on Special Tax Credits for more details.

Capital Gains on Future Sale

While not immediately relevant, it’s important to plan ahead. If you sell your primary residence after living there for at least two out of the five years prior, up to $250,000 ($500,000 for married couples) of gains are exempt from federal capital gains tax.

State and Local Tax Variations

Taxes on new construction homes vary wildly by state and municipality, impacting analysis of where to build or buy your new home. Let’s examine some key differences across regions.

High vs. Low Property Tax States

• High Tax States: New Jersey, Illinois, New Hampshire, Connecticut, and New York.
• Low Tax States: Hawaii, Alabama, Louisiana, Delaware, and West Virginia.

States With No Property Tax

No state has outright “no property tax,” as property taxes are local. However, some states have lower average tax rates due to low local levies or generous exemptions.

Sales Tax on Labor and Materials

• No Sales Tax States: Alaska, Delaware, Montana, New Hampshire, and Oregon.
• Some states, like New Mexico or Hawaii, tax labor in addition to materials; others only tax materials.

Special Purpose Taxes

Some municipalities levy “impact fees,” “school taxes,” or “infrastructure taxes” on new construction to fund roads, schools, or utilities. These can be significant and affect the cost of new builds.

Case Example: Texas vs. California

• Texas: No state income tax, but high local property taxes. Few exemptions on new construction, but rapid property value increases can trigger higher bills post-construction.
• California: High land values, but property tax increases capped by Prop 13. Special assessments (“Mello-Roos” taxes) on new developments can be substantial.

Check Local Ordinances Carefully

Before buying or building, always consult the county tax assessor and local ordinances for the full picture—local rules and exceptions can add major costs.

Hidden Tax-Related Fees and Costs

In addition to headline property and transfer taxes, new construction buyers face a host of other tax-linked charges at closing and beyond. Being aware of these helps avoid unwelcome surprises.

Impact Fees

Cities and counties often charge “impact fees” on new homes to offset the burden on roads, sewers, utilities, and schools. These can range from a few thousand to tens of thousands of dollars, depending on the region.

Special Assessment Districts

If a new development is in a Community Facilities District (CFD), Mello-Roos district (California), or Special Purpose District, additional annual or monthly assessments will be tacked onto your tax bill.

Bond Repayment Fees

Many new subdivisions issue municipal bonds to fund infrastructure, with repayment collected via special property taxes or utility surcharges.

Homeowners Association (HOA) Fees

While not strictly taxes, HOA dues often cover services normally funded through property taxes, such as trash pickup or landscaping. In some cases, they’re added as a quasi-local tax, especially in planned developments.

Utility Connection Fees

Connection and hookup fees for electricity, gas, water, and sewer may be wrapped into property taxes, charged up front, or billed over time via tax assessments.

Permitting and Inspection Fees

These are typically charged during construction and may be bundled into building costs, but they affect the overall tax basis of the property.

Strategies for Reducing Tax Liability in New Construction

Smart planning can help new construction homeowners minimize their tax exposure. Here’s how to keep more of your hard-earned money:

Apply for all available exemptions and abatements

• Homestead exemption (for primary residences)
• Senior, disabled, veteran, and first-time buyer exemptions
• Abatements for new construction, energy efficiency, or historic preservation

Time Your Purchase Strategically

Closing at the right time (e.g., early in the year vs. late in the year) can impact which party is responsible for taxes at closing and how soon the new, higher assessment will take effect. Consult your agent and tax advisor.

Appeal Inflated Assessments

If the assessor overvalues your property, gather comps, builder receipts, and evidence of unique circumstances. Many U.S. counties have official appeal processes—don’t hesitate to initiate one.

Retain Documentation

Keep all closing statements, tax bills, and documentation of exemptions for at least seven years, protecting yourself in case of audit or appeals.

Hire Professionals

• Consult CPAs for federal and state tax advice, especially if planning energy-efficient features or significant upgrades.
• Use local real estate attorneys or experienced agents who know the intricacies of local taxing authorities and can help identify potential abatement programs.

Special Tax Credits and Incentives for Energy-Efficient and Green Construction

Building an energy-efficient or green-certified home may unlock valuable federal, state, and utility-backed tax credits and rebates, easing the up-front costs and long-term tax burden.

Federal Energy Tax Credits

• Energy-Efficient Home Construction (IRC Section 45L): Homebuilders (including owner-builders of custom homes) can claim a federal credit of up to $5,000 for each new single-family or manufactured home that meets certain standards as of 2023, subject to inflation adjustments. Multi-family credits also available.
• Residential Clean Energy Credit (previously ITC): Homeowners can claim a credit of 30% of the cost of new solar, geothermal, wind, or battery storage systems through 2032, decreasing thereafter.

State and Utility Rebates

Many states and local utilities offer rebates or property tax reductions for certified energy-efficient homes, green roofs, smart home technology, or EV charging installations.

How to Qualify

• Work with an energy rater or certified Home Energy Rating System (HERS) inspector to document your home’s efficiency.
• File the proper forms (usually IRS Form 5695 or 8908) with your federal taxes.
• Apply for state or local programs upon completion and keep all invoices and certification paperwork.

LEED, ENERGY STAR, and Other Certifications

Some city and state incentive programs require completion of third-party certifications such as ENERGY STAR, LEED, or the National Green Building Standard for eligibility.

Taxes on New Construction Investment Properties

If you’re building new construction as a rental or investment property, the tax implications change—often becoming more complex but potentially more advantageous, depending on how you structure your finances.

Depreciation Deductions

Owners of investment properties can depreciate the cost of a new building (not land) over 27.5 years for residential and 39 years for commercial properties, offsetting rental income each year. Construction costs added after purchase (capital improvements) can also be depreciated.

Deducting Expenses

• Mortgage interest and property taxes
• Insurance and certain closing costs
• Repairs, utilities, and management fees
• HOA dues, special assessments

Understanding Passive Loss Rules

Most rental real estate losses are "passive," deductible only against passive income unless you qualify as a real estate professional. Consult a CPA to optimize your deductions.

Taxation on Sale and 1031 Exchanges

Capital gains, depreciation recapture, and the use of like-kind (1031) exchanges are major tax planning strategies for new construction investors, allowing deferral of taxes by exchanging into another investment property.

Comparing Taxes: Residential vs. Commercial New Construction

The line between residential and commercial construction changes what taxes and deductions apply. Here’s a comparison of the main differences:

Property Tax Rates

• Commercial property rates are generally higher than residential rates in most jurisdictions.
• Assessments for commercial properties may consider income-producing potential, not just value of construction.

Sales Tax Rules

• More likely for labor and certain finish items to be taxable on commercial builds, especially tenant improvements.
• Eligibility for exemptions is often stricter.

Abatement and Incentives

• Commercial new builds may qualify for local business incentives, but fewer residential tax abatement programs apply.
• Special credits for low-income housing, green building, or historic rehab may benefit both, depending on use and location.

Depreciation Schedules

• Commercial properties depreciate over 39 years; residential over 27.5.
• Cost segregation studies can accelerate depreciation (especially for commercial spaces), optimizing cash flow.
