Seminole County property tax is your property’s taxable value multiplied by the combined millage rate set by the county, school board, your city, and any special districts that cover your parcel. The Property Appraiser sets that value as of January 1, then subtracts the exemptions you’ve filed for. The Tax Collector mails bills in November and gives you a 4% discount for paying that month, with the full amount due by March 31.
How Your Bill Is Calculated
Every parcel starts with a “just value,” the Property Appraiser’s estimate of what it would sell for on the open market as of January 1.1Florida Department of Revenue. Property Tax Information for First-Time Florida Homebuyers Assessment caps and exemptions reduce that figure to your taxable value.
Taxing authorities then apply their millage rates. A mill is one dollar of tax per $1,000 of taxable value.2Florida Department of Revenue. A Florida Homeowner’s Guide: Millage Several bodies levy on the same property: the Seminole County Board of County Commissioners, the School Board, cities, and special districts such as water management. Your bill is the sum of each authority’s rate times your taxable value. Combined rates typically run 17 to 20 mills depending on where you live in the county, and the exact figure changes each fiscal year.
The Homestead Exemption and Save Our Homes Cap
If you own and permanently live in a Seminole County home, the homestead exemption is the biggest reduction available. It removes up to $50,000 from your assessed value, but it isn’t a flat number. The first $25,000 applies to all taxes, including school district levies. The second $25,000 applies only to non-school taxes and only to assessed value between $50,001 and $75,000.3The Florida Legislature. Florida Code 196.031 – Exemption of Homesteads A home assessed at $60,000 or less won’t get the full $50,000 reduction.
File your application with the Seminole County Property Appraiser by March 1 of the year you want the exemption. Miss that date and the exemption is gone for the full year.4The Florida Legislature. Florida Code 196.011 – Annual Application Required for Exemption The office lets you pre-file online, and the 2026 deadline is March 2, 2026.5Seminole County Property Appraiser. Seminole County Property Appraiser Homepage You’ll need proof of Florida residency such as a Florida driver’s license and vehicle registration showing the property address.
Once homestead is in place, the Save Our Homes amendment limits annual increases in your assessed value to 3% or the change in the Consumer Price Index, whichever is lower.6The Florida Legislature. Florida Code 193.155 – Homestead Assessments In a rising market, that cap can open a wide gap between assessed value and actual market value, saving thousands per year. Non-homestead residential property has its own cap at 10% per year.7Florida Senate. Florida Code 193.1554 – Assessment of Nonhomestead Residential Property
Portability When You Move
Sell your homesteaded home and buy another primary residence in Florida, and you can carry your Save Our Homes savings with you. Portability transfers the difference between your old home’s market and assessed values to your new home, up to $500,000.6The Florida Legislature. Florida Code 193.155 – Homestead Assessments It works whether you move within Seminole County or to any other Florida county.
You must establish a new homestead within three tax years of giving up the old one and file Form DR-501T with the Property Appraiser by March 1. Say your 2024 home had a market value of $350,000 and an assessed value of $200,000. That $150,000 gap is portable. Move to a home of equal or greater market value and the full $150,000 transfers. Move to a less expensive home and the savings are reduced proportionally based on the ratio of new to old market values.
People lose this benefit regularly by not filing the separate form. Applying for homestead on the new home does not trigger portability. A late filing can be applied going forward, but no refunds are available for years you missed.
Other Exemptions Worth Checking
Veterans
Honorably discharged veterans with a service-connected disability of 10% or more get a $5,000 reduction in assessed value. It isn’t limited to homestead property and extends to the veteran’s unremarried surviving spouse.8The Florida Legislature. Florida Code 196.24 – Exemption for Disabled Ex-Servicemember or Surviving Spouse Veterans with a total and permanent service-connected disability pay no property tax on their homestead at all.9The Florida Legislature. Florida Code 196.081 – Exemption for Certain Permanently and Totally Disabled Veterans and for Surviving Spouses of Veterans
Surviving Spouses, Blind Persons, and Persons With Disabilities
Each category is entitled to a $5,000 reduction in assessed value. Disability must be certified by a licensed Florida physician, the Social Security Administration, or the U.S. Department of Veterans Affairs.10The Florida Legislature. Florida Code 196.202 – Property of Widows, Widowers, Blind Persons, and Persons Totally and Permanently Disabled
Seniors 65 and Older
Homestead owners 65 or older whose total household income stays under an annually adjusted limit can qualify for an additional exemption of up to $50,000. The 2026 income threshold is $38,686.11City of Jacksonville. Senior Citizen Homestead Exemptions Household income includes the adjusted gross income of everyone in the home. The exemption only applies where the local county or municipality has adopted it by ordinance.12Florida Senate. Florida Code 196.075 – Additional Homestead Exemption for Persons 65 and Older Seminole County has, so qualifying seniors should file with the Property Appraiser.
Business Tangible Personal Property
Business equipment, furniture, and fixtures are taxed separately from real estate. Each tangible personal property account is eligible for up to a $25,000 exemption.13Florida Senate. Florida Code 196.183 – Exemption for Tangible Personal Property Businesses with $25,000 or less in total value file an initial return and can skip later returns while they stay under the threshold. Over $25,000, Form DR-405 is due by April 1 each year. Failing to file can trigger a penalty of 25% of the total tax owed.
What a Sale Does to the Tax Bill
Buyers get burned by this one often. When a property changes hands, Florida law strips existing exemptions and resets the assessed value to full market value as of the January 1 after purchase. If the seller held homestead for 15 years with Save Our Homes holding assessed value far below market, a new buyer’s bill can easily double or triple what the seller was paying. Before you close, ask the Appraiser’s office for the property’s full market value so you can estimate your actual tax exposure rather than trusting the seller’s current bill.
Paying Your Bill
The Seminole County Tax Collector mails tax bills in November. Florida law builds in a graduated discount for early payment: 4% in November, 3% in December, 2% in January, 1% in February, no discount in March, and the full amount due by March 31.14The Florida Legislature. Florida Code 197.162 – Tax Discount Payment Periods On a $4,000 bill, paying in November saves $160.
You can pay online through the Seminole County Tax Collector’s website, by mail to P.O. Box 630, Sanford, FL 32772, or in person at one of their office locations.15Seminole County Tax Collector. Property and Tangible Taxes Credit card payments carry a convenience fee of roughly 2% to 2.4%. E-checks are cheaper. If you mail payment, include the voucher from your bill so the funds hit the right parcel.
Quarterly Installment Plan
Florida also offers an installment plan that spreads your annual tax across four quarterly payments with built-in discounts. To enroll, submit your application to the Tax Collector by April 30 of the year before the taxes are due, and your estimated taxes must exceed $100.16Florida Department of Revenue. Application for Installment Payment of Property Taxes Payments and discounts fall on these dates:
- June 30: first quarter, 6% discount
- September 30: second quarter, 4.5% discount
- December 31: third quarter, 3% discount
- March 31: fourth quarter, no discount
You’re locked into the plan once the Tax Collector receives your first payment by July 31.
What Happens If You Don’t Pay
Unpaid taxes go delinquent on April 1 and start accruing interest at 18% per year, with a minimum charge of 3%.17Florida Senate. Florida Statutes Chapter 197 – Tax Collections, Sales, and Liens Advertising costs get tacked on, plus a $10 fee per delinquent taxpayer. From that point you must pay with certified funds only: cash, cashier’s check, or money order.15Seminole County Tax Collector. Property and Tangible Taxes
If taxes stay unpaid, the Tax Collector sells a tax certificate on the property on or before June 1. A certificate is a lien, not a sale of the home. Investors bid by offering the lowest interest rate they’ll accept, down to 0%, with a maximum of 18%. The investor pays off your delinquent taxes, and you then owe the investor the face amount plus interest. Certificate holders earn at least 5% regardless of the winning bid.18The Florida Legislature. Florida Code 197.432 – Sale of Tax Certificates
Two years after April 1 of the year the certificate was issued, the certificate holder can file a tax deed application. That starts a public auction of your property conducted by the Clerk of the Circuit Court. The application fee is $75, and the certificate holder must also pay off any other outstanding certificates and delinquent taxes on the parcel.19Florida Senate. Florida Code 197.502 – Tax Deed Applications The full timeline from first delinquency to losing the property runs years, but costs start compounding the moment a certificate sells.
Appealing Your Assessment
Every August the Property Appraiser mails a Truth in Millage (TRIM) notice showing your assessed value, exemptions, and proposed taxes from each authority. Read it when it arrives. If the assessed value looks too high, you have two paths.
The informal route is to call the Property Appraiser’s office. Staff are required to be available for informal conferences, and many disputes resolve there without fees or paperwork.
If that doesn’t work, file a formal petition with the Value Adjustment Board within 25 days of the TRIM notice mailing date.20Florida Senate. Florida Code 194.011 – Assessment Notice; Objections to Assessments The board may charge up to $15 per parcel, and no more than $5 per parcel for joint petitions. There’s no fee for appeals of denied homestead exemptions.21The Florida Legislature. Florida Code 194.013 – Filing Fees for Petitions
At the hearing a special magistrate weighs evidence from you and from the Property Appraiser’s office. Bring recent sales of comparable homes in your neighborhood, an independent appraisal, or documentation of structural problems that reduce value. Hard numbers win; a general sense that your taxes are too high doesn’t.
