Property Tax Prorations at Closing — How They Work in Walton County

Property tax prorations are one of the more confusing line items on a Walton County 30A closing because Florida property taxes work differently from most states. They are paid in arrears, billed in November of each year, and discounted by month. The actual bill for the year is rarely available at closing during most of the year — so prorations are estimated. Here is exactly how Walton County tax prorations work, with worked examples.

Florida property tax basics

Walton County property taxes (and Florida property taxes generally) cover the calendar year January 1 through December 31. The Property Appraiser sets the assessed value as of January 1. The Tax Collector mails bills on November 1 of the same year. Bills are due March 31 of the following year. They become delinquent April 1.

The November discount

Florida rewards early payment with a sliding discount:

• 4% discount if paid in November.
• 3% discount if paid in December.
• 2% discount if paid in January.
• 1% discount if paid in February.
• Full amount due by March 31; delinquent April 1.

On a $14,000 Walton County 30A tax bill, the November-discount payment is $13,440 — a $560 savings. AquaRK’s closing instructions reflect the November discount when it applies.

How proration is actually calculated

At closing, the seller credits the buyer for the seller’s share of the year’s taxes — January 1 through the closing date — and the buyer is responsible for the full bill when it arrives in November. The math is straightforward when the current year bill is known, and estimated when it is not.

Example 1 — closing in March before the bill is set. Last year’s Walton County tax bill on the property was $12,000. Closing date March 15. AquaRK uses the prior-year bill as an estimate. The seller’s share is 73 days of the year (Jan 1–Mar 14). 73/365 × $12,000 = $2,400 credit to buyer at closing. The buyer will receive the actual current-year bill in November and pay the full amount, having already received the seller’s estimated share at closing.

Example 2 — closing in November after the bill is set. Current-year bill is $14,200. Closing November 20. Seller’s share is 324 days. 324/365 × $14,200 = $12,604 credit to buyer at closing. The buyer pays the full $14,200 in November (or December) and is essentially even — having received the seller’s share at closing and paying the full bill themselves.

What "Save Our Homes" and the non-homestead cap mean

Florida’s Save Our Homes amendment caps annual assessed-value increases at 3% on Florida-resident homestead properties. It does not apply to 30A second homes or vacation rentals. Non-homestead properties are subject to a separate 10% annual cap on assessed value (with carve-outs). Practical consequence: 30A second homes that have appreciated significantly will see their assessed value jump in the year following sale because the seller’s historical assessment cap (if any) does not transfer to the buyer.

"Reassessment on sale" — the 30A buyer surprise

When a 30A property sells, the Walton County Property Appraiser reassesses the property to current market value as of the next January 1. A property assessed at $850,000 under the prior owner that just sold for $1,750,000 will be reassessed in the next tax cycle. The buyer should plan for a meaningfully higher tax bill the year after purchase.

CDD and special assessment districts

Several 30A communities sit inside Community Development Districts (CDDs) or special assessment districts that add a non-ad valorem line item to the tax bill. WaterColor, WaterSound Origins, and several other large developments include CDD assessments that fund infrastructure. These appear on the same Walton County tax bill and are prorated the same way.

Escrow accounts on financed purchases

Lenders typically collect 1/12 of the annual estimated tax at each monthly payment and pay the bill from escrow. At closing, the lender will collect a "cushion" — usually two to three months of taxes — to start the escrow account. This shows up on page 2 of the Closing Disclosure under section G.

How AquaRK handles tax prorations on 30A

We pull the actual prior-year bill (or current bill if available) from the Walton County Tax Collector, calculate the proration through the agreed closing date, and reflect both the seller credit and the buyer’s November obligation in clear language on the ALTA Settlement Statement. If a re-proration is needed once the actual current-year bill is issued (rare but possible on contract terms requiring it), we manage that post-closing.
