Why Are Taxes Higher on New Construction?

Property taxes are a primary source of revenue for local governments, supporting public services like schools, roads, police, and fire departments. When individuals purchase a newly constructed home, they often find their initial property tax bill is higher than for an existing property of similar value. This article explains why new construction often has a higher tax burden than established properties.

Differences in Property Valuation

The primary factor contributing to higher property taxes on new construction is the method and timing of property valuation. Existing properties are assessed based on a previous cycle’s value, which may not reflect current market value. Many jurisdictions implement assessment caps, limiting annual increases to a fixed percentage or the rate of inflation. This means an older home’s assessed value can lag behind its current market value, especially in appreciating areas. For example, a home purchased for $200,000 twenty years ago might have an assessed value of $250,000 due to these caps, even if its current market value is $500,000.

In contrast, new construction is assessed at its current market value or recent sales price upon completion and sale. There is no prior assessment history or cap, so the property’s full value is recognized for taxation from day one. If a new home sells for $500,000, its initial assessed value will likely be that full amount, representing 100% of its market value. This immediate valuation at full market price translates to a higher assessed value compared to an existing property with a suppressed assessed value. The difference in tax bills often stems from this disparity in assessed value rather than a higher tax rate applied to new construction.

Consider two identical homes, both with a current market value of $500,000, located in the same tax district with a property tax rate of 1.25%. An existing home, purchased two decades ago, might have an assessed value of $250,000 due to assessment caps. Its annual tax bill would be approximately $3,125 ($250,000 x 0.0125). A newly constructed home, however, would be assessed at its full market value of $500,000. This new home would face an annual tax bill of $6,250 ($500,000 x 0.0125), representing a significantly higher payment despite the similar market value.

This difference highlights how the “higher tax” results from a higher assessed value for new construction. The timing of the assessment plays a significant role, as new homes are taxed at their current value without historical assessment limitations. This immediate full valuation ensures new properties contribute to the tax base commensurate with their market worth from the moment they are sold. Property assessments are periodically reviewed, but the initial assessment of new construction sets a high baseline.

Impact of Special Assessments and Development Costs

New construction often incurs special assessments, which contribute to a higher overall tax bill. These assessments are distinct from general property taxes and fund infrastructure and public services within a defined development area. Examples include new roads, water and sewer systems, stormwater drainage, streetlights, schools, parks, or community centers. These costs are often financed through municipal bonds, like Community Development District (CDD) or Mello-Roos bonds, repaid by property owners over many years.

Special assessments are common in new construction areas because existing communities already have their infrastructure in place. Costs for established systems were paid by previous taxpayers or are maintained through general property tax revenues. In contrast, new developments require new infrastructure to support homes and residents. These development costs are then distributed among property owners within the new community. For instance, a new home might have an annual CDD assessment of $1,500 to $3,000 in addition to its regular property taxes, depending on the scope of the amenities and the bond structure.

These charges are itemized separately on the property tax bill and are distinct from the ad valorem (based on value) property tax levied by counties or cities for general government operations. Property owners in new developments bear the direct cost of the infrastructure that makes their community livable. These special assessments can add thousands of dollars annually to a new homeowner’s total property tax liability, making the overall burden higher than that of an older home in an established area where infrastructure costs are amortized or covered by the general tax base.

Timing of Tax Exemptions

The timing of property tax exemptions can also contribute to a higher initial tax bill for new construction. Many jurisdictions offer property tax exemptions to reduce a homeowner’s taxable value, lowering their overall tax burden. Common examples include the homestead exemption for primary residences, exemptions for senior citizens, and exemptions for military veterans or their surviving spouses. These exemptions can reduce the assessed value by a fixed dollar amount or a percentage.

Homeowners purchasing new construction may not qualify for these exemptions during their initial tax period. Property tax exemptions have specific application deadlines, often in the early months of the calendar year for the upcoming tax year. If a new home is purchased later in the year, the new homeowner might miss the window to apply for exemptions for the current or following tax year. This situation results in the first property tax bill reflecting the full, unexempted assessed value of the new home.

In contrast, long-term residents in existing homes already benefit from these exemptions, which are automatically renewed each year unless there is a change in ownership or eligibility. Their property tax bills already reflect the reduced taxable value provided by these benefits. While new homeowners can apply for exemptions in subsequent tax cycles, the initial period can present a higher tax obligation because reductions have not yet been applied. For example, a homeowner might pay an extra $500 to $1,000 in their first year’s taxes if they miss the opportunity to claim a homestead exemption.
