Are you buying or selling in Aventura and wondering how Florida’s homestead and portability rules can lower your property taxes? The timeline and paperwork matter, especially around January 1 and March 1. With a little planning, you can protect your Save Our Homes benefit and avoid surprises. Here is what you need to know, step by step, for Aventura and Miami‑Dade County. Let’s dive in.
Homestead basics in Aventura
Florida’s homestead exemption reduces the taxable value of your primary residence. To qualify, you must own and occupy the property as your permanent residence on January 1 of the tax year and file with the Miami‑Dade Property Appraiser. You can review eligibility and filing details on the county’s homestead page and FAQs from the Miami‑Dade Property Appraiser.
- Learn how to apply and file online on the Miami‑Dade homestead page: Homestead filing and deadlines
- Read common requirements on the county FAQ: Miami‑Dade exemptions FAQ
Florida’s Save Our Homes (SOH) cap limits the annual increase in your assessed value to the lower of 3% or last year’s CPI change once your homestead is in place. See the cap in state law: Section 193.155, Florida Statutes.
Key 2025 update
Voters approved Amendment 5, which adds an annual inflation adjustment to the additional homestead exemption for non‑school taxes starting January 1, 2025. Get the update here: Amendment 5 overview.
Deadlines and your yearly timeline
- File new homestead and portability applications by March 1 for the current tax year in Miami‑Dade. Review how to file online or in person: Homestead filing and deadlines.
- Miami‑Dade mails TRIM notices in late August. Check your proposed value, exemptions, and whether portability was applied. Learn the process and appeal window on the TRIM page: Notice of Proposed Property Taxes.
- If you miss March 1, some late filings may be reviewed through the Value Adjustment Board petition period after TRIM (generally 25 days from mailing). See rule guidance: Florida Administrative Code 12D‑8.0065.
Portability explained
Portability lets you transfer your accumulated SOH benefit (the difference between your prior home’s just value and its capped assessed value) to a new Florida homestead. Miami‑Dade explains how it works and how to apply: Portability guidance from Miami‑Dade.
- What transfers: the SOH assessment difference from your prior Florida homestead.
- Filing form: submit Form DR‑501T with the county where your new homestead is located.
- Maximum transfer: up to $500,000 in most upsizing cases. See rule and limits: F.A.C. 12D‑8.0065.
Time window to port
You have up to three assessment years to establish the new homestead and file DR‑501T. The clock starts January 1 of the last year you had a qualified homestead. Details are outlined here: F.A.C. 12D‑8.0065.
Upsize vs. downsize
- If your new home’s just value is equal to or higher than your prior home’s just value, you may transfer up to your full eligible SOH difference (capped at $500,000).
- If your new home’s just value is lower, the transferred amount is proportionally reduced. Miami‑Dade provides examples and guidance: Portability guidance from Miami‑Dade.
How to file in Miami‑Dade
Follow these steps to keep your benefit when moving to or within Aventura:
- Confirm primary residence status by January 1
- Be the owner and occupy the property as your permanent residence on January 1 for homestead eligibility.
- Abandon the prior homestead
- If you are keeping the old property, make sure it is not your primary residence as of January 1. You can still port after converting a prior homestead to a rental if you properly abandon it. See a county explainer: Portability of Save Our Homes.
- File by March 1
- File your homestead application and submit DR‑501T for portability with Miami‑Dade. Start here: Homestead filing and deadlines and Portability guidance from Miami‑Dade.
- Moving across counties
- If your prior homestead was outside Miami‑Dade, the Miami‑Dade Property Appraiser will coordinate certification with the prior county after you file DR‑501T.
- Special situations for spouses
- If you need to designate shares of a prior homestead’s assessment difference (such as after a divorce), spouses may use Form DR‑501TS as outlined in the rule: F.A.C. 12D‑8.0065.
- Verify on your TRIM notice
- In late August, confirm the portability reduction appears on your TRIM notice. If it is missing or denied, contact the Property Appraiser or consider a VAB petition within the deadline: TRIM and appeal timeline.
Documents you will likely need
- Proof of Florida residency and occupancy as of January 1 (for example, Florida driver’s license or voter registration)
- Deed or closing statement
- Social Security number (for application identification)
- Prior property tax account information, if available
- Completed DR‑501T and, if applicable, DR‑501TS
See Miami‑Dade’s documentation guidance here: Exemptions FAQ.
Common Aventura scenarios
Moving within Miami‑Dade
- You still need to file DR‑501T on your new homestead. The county handles internal certification. See steps: Portability guidance from Miami‑Dade.
Moving from another Florida county
- File DR‑501T with Miami‑Dade. Miami‑Dade will request certification from the prior county. Keep prior tax notices handy.
Moving out of Florida
- Portability applies only between Florida homesteads. If you leave the state, the SOH benefit does not follow you unless you reestablish a Florida homestead within the three‑year window.
Two owners combining households
- If each owner had a separate Florida homestead, the highest prior SOH assessment difference may transfer to the new shared homestead (subject to limits and documentation). See local guidance: Portability guidance from Miami‑Dade.
Divorce, death, and title changes
- These events do not automatically end portability rights, but documentation is required. Review the rule framework here: F.A.C. 12D‑8.0065.
Smart timing tips
- Aim to close and occupy before January 1 if you want homestead for that tax year.
- File homestead and DR‑501T early, well before March 1, preferably online through Miami‑Dade.
- Keep copies of prior-year tax notices and your prior homestead details for certification.
- In late August, review your TRIM notice and act quickly if anything is missing.
A clear plan built around January 1, March 1, and the three‑year portability window can help you keep more of your Save Our Homes benefit when you move in Aventura.
