What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About San Sebastián Municipio, PR

San Sebastián Municipio carries an effective property tax rate of 0.268%, which sits well beneath Puerto Rico's statewide median of 0.389% and ranks 53rd among the island's 72 counties. Against the national median of 0.794%, the gap widens further—San Sebastián's rate is roughly a third of what a comparable mainland jurisdiction might charge. That difference shows up in real dollars: with a median home value of $115,000, the median annual tax bill comes to just $308. Households here earn a median of $19,920, with per-capita income at $12,443, so property taxes absorb a meaningful but contained share of local budgets. The low rate may reflect a thinner tax base and limited municipal services rather than broad prosperity, since incomes trail mainland norms considerably.

Frequently asked questions

What is the property tax rate in San Sebastián Municipio, PR?
The effective rate is 0.27% — meaning the median tax bill equals about 0.27% of the median home value.
How much are property taxes on a median home?
On the median home ($115,000), the estimated annual bill is about $308.
Is San Sebastián Municipio's rate high or low?
Compare it to the state median of N/A and the national average near 1.1%.
How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the San Sebastián Municipio assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the San Sebastián Municipio assessor within the local deadline, typically with comparable sales as evidence.
