Homestead portability Florida movers use transfers the accumulated Save Our Homes benefit from a prior homestead to a new one, up to a dollar cap.

It lowers the new home's assessed value, the tax bill and the escrow payment. File it with the homestead application. Our guide to the Florida homestead exemption covers the base exemption.

What portability transfers

The difference between your old home's market value and its capped assessed value.

The Florida Department of Revenue portability page explains the calculation.

Up to $500,000 of that difference.

Applied to reduce the new home's assessed value.

The new cap then grows from the reduced base.

Who qualifies

Anyone who held a Florida homestead and establishes a new one within three tax years.

The old homestead must have been abandoned.

Moving within Florida; out-of-state buyers have nothing to port.

See our guide to moving to Florida and getting a mortgage.

Both spouses' prior homesteads can combine in some cases.

Moving up

To a more valuable home, the full accumulated benefit transfers, up to the cap.

The new assessed value is market value minus the ported amount.

See our guide to property tax estimates for new buyers in Florida.

A long-time owner can cut the new bill substantially.

The largest benefit goes to those who held the longest.

Moving down

To a less valuable home, the benefit transfers proportionally.

The percentage of the old home's value that was sheltered shelters the same percentage of the new.

Still meaningful.

Retirees downsizing use it constantly.

See our guide to buying a home near retirement in Florida.

The deadline

File by March 1 of the year after you establish the new homestead.

The three-year window runs from the January after you left the old home.

Miss it and the benefit is lost.

Late filing has narrow exceptions.

Calendar it at closing.

How to file

Form DR-501T with the homestead application at the county property appraiser.

The old county's appraiser confirms the prior benefit.

Counties coordinate.

Online in most counties.

Bring the old address and the closing date.

Effect on the mortgage

The lender's escrow is set from the current tax bill.

See our guide to escrow accounts in Florida.

A ported benefit lowers the reset bill and the year-two payment.

Tell the lender the expected ported amount for the qualifying estimate.

Some lenders will use it; some use the unreduced figure.

Selling and buying timing

Sell first and buy within three years: the benefit waits.

Buy first and sell later: file for the new homestead and port once the old one is abandoned.

See our guide to bridge loans versus HELOCs in Florida.

Two homesteads at once is not allowed.

Abandon the old one in writing.

Divorce and portability

Spouses who split can divide the benefit by agreement.

See our guide to divorce and your mortgage in Florida.

The decree or a written designation sets the split.

Each carries their share to a new home.

File the designation with the appraiser.

Death of a spouse

A surviving spouse keeps the full benefit on the same home.

See our guide to the mortgage after the death of a spouse in Florida.

Moving later, the survivor ports it.

Heirs who did not live there cannot.

The benefit belongs to the homesteader.

New construction

Port to a newly built home once it is your homestead.

See our guide to new construction mortgages in Florida.

The first full assessment captures the finished value; portability reduces it.

File the year after moving in.

The three-year window still applies from leaving the old home.

Condos and partial interests

Portability applies to any homestead property type.

Co-owners who each held homestead can each port their share.

See our guide to tenants in common versus joint tenancy in Florida.

The appraiser apportions.

Ask before closing.

What it does not do

It does not reduce non-ad valorem assessments.

See our guide to CDD fees in Florida.

It does not apply to second homes or rentals.

See our guide to the non-homestead cap in Florida.

It does not carry out of state.

Estimating the benefit

Old home's market value minus its assessed value, from the last TRIM notice.

See our guide to TRIM notices in Florida.

Cap it at $500,000.

Subtract from the new home's market value for the new assessed value.

Multiply by the millage for the tax saved.

Common mistakes

Missing the March 1 deadline.

Assuming it happens automatically.

Forgetting to abandon the old homestead.

Renting the old home before filing, which ends the old homestead early.

See our guide to house poor in Florida for what a lost benefit costs.

A worked example

A twenty-year owner whose old home's market value sits far above its capped assessment.

The difference, under the cap, ports to a new home of higher value.

The new assessed value drops by that amount from day one.

The tax bill and the escrow follow.

Filed in January with the homestead application.

Timing the closing

A January closing on the new home and a homestead filing the same month keeps the sequence clean.

A December closing means filing within weeks.

The appraiser needs the old county's confirmation, which takes time.

File early in the year regardless.

Ask the appraiser for a receipt.

Where to start

Pull your last TRIM notice and compute the market-minus-assessed difference.

Note the three-year window and the March 1 deadline.

Then start a conversation and we will put the ported estimate into the payment for the new home.
