This post uses hypothetical scenarios for illustrative purposes only. It does not describe any actual client, transaction, or representation, and is not legal advice.
Here is how this usually shows up. A founder sells a Florida operating business — say a distribution company that owns its warehouse — and the buyer cannot or will not finance the whole price in cash, so part of the consideration becomes a seller note. To protect the seller, the parties agree the note will be secured, and because the company owns real estate, the cleanest collateral is a mortgage on the warehouse. Everyone is comfortable. The lawyers paper a promissory note and a mortgage, the closing statement gets drafted, and someone pencils in Florida documentary stamp tax on the note. What the model usually misses is the second Florida tax that the mortgage just triggered — a one-time nonrecurring intangible tax of two mills on the secured obligation — and on a seven-figure note that omission is real money landing on the closing statement at the worst possible moment.
Two different Florida taxes attach to the same secured note
Florida taxes a promissory note and a mortgage as two separate events, and a deal model that captures only one of them is short. The first is the documentary stamp tax on the note itself, which Florida imposes on written obligations to pay money at 35 cents per $100 — a tax that runs on the note whether or not it is secured. That is the one most people remember, and it is the subject of its own set of traps when a deal uses seller notes in a Florida asset deal.
The second tax is the one that gets dropped. When the note is secured by a mortgage, deed of trust, or other lien on real property located in Florida, Section 199.133 imposes a nonrecurring intangible tax of two mills — that is, $2 per $1,000, or 0.2% — on the just valuation of the obligation, to the extent it is secured by the Florida real property. This is a survivor. Florida repealed its annual intangible personal property tax effective in 2007, and a lot of practitioners filed “Florida intangible tax” away as a dead letter. But the Legislature kept the nonrecurring tax alive; Chapter 199 was restructured rather than repealed, and the nonrecurring levy on obligations secured by Florida realty is still on the books and still collected when the mortgage is recorded. Treating it as abolished is a common and expensive mistake.
What the number actually comes to
The two taxes stack, and it helps to see them together on a representative set of figures. Take a seller note of $2,000,000 secured by a mortgage on Florida real estate. The documentary stamp tax on the note runs at 35 cents per $100, which is roughly $7,000. The nonrecurring intangible tax under Section 199.133 runs at two mills on the secured amount, which is $4,000. So the act of securing the note with Florida real property does not add a rounding error — it adds approximately $4,000 in nonrecurring intangible tax on top of the doc stamp the parties already expected, and the combined Florida tax on putting a secured seller note in place is on the order of $11,000. On larger notes the gap scales linearly. A model that captured only the doc stamp is understating the closing-day cost of the financing by the entire intangible-tax line.
One nuance keeps the number honest. The nonrecurring tax reaches the obligation only to the extent it is secured by Florida real property. If a $2,000,000 note is secured by a mortgage on Florida real estate but the real estate is appraised below the note — or the note is only partially secured by the realty and partially by other collateral or unsecured — the tax is measured by the portion attributable to the Florida real property, not automatically the full face of the note. That is a place where careful drafting and a defensible valuation matter, because the tax base is the secured amount, not the headline number.
Who pays it, and why that belongs in the LOI
The dollars are only half the problem; the other half is that nobody agreed who bears them. Because the nonrecurring intangible tax and the documentary stamp tax both arrive at recording, they get treated as closing costs, and if the purchase agreement is silent the question of who pays becomes a closing-table argument at the moment everyone least wants one. The fix is to allocate both Florida taxes expressly — doc stamp on the note and nonrecurring intangible tax on the mortgage — in the same provision of the purchase agreement that handles transfer taxes and recording costs, and to do it at the letter-of-intent stage when the parties still have room to trade. A buyer who agreed to “pay all transfer taxes” without understanding that securing the seller note pulls in a separate intangible tax has agreed to more than it priced; a seller who assumed the buyer was covering recording costs may find the burden flipped. Pinning it down early is cheaper than discovering it at funding.
There is also an interaction worth flagging for the people structuring the note’s economics. Sellers often dress up a seller note with rate kickers, earnout-linked bumps, or contingent additions, and those features raise their own Florida usury questions on seller notes. The tax analysis and the usury analysis look at the same instrument from different angles, and changing the secured amount or the structure to solve one can move the other. The note, the mortgage, the tax allocation, and the rate terms should be drafted as a single coordinated package rather than four documents that each solved their own problem.
The takeaway
Securing a Florida seller note with a mortgage on the target’s real estate triggers two separate Florida taxes, not one. The documentary stamp tax on the note at 35 cents per $100 is the one everyone budgets; the Section 199.133 nonrecurring intangible tax at two mills on the secured obligation is the one that gets dropped because people wrongly assume Florida’s intangible tax died in 2007. It did not — the nonrecurring levy survived the repeal and is collected when the mortgage records. Run both numbers, measure the intangible tax against the amount actually secured by Florida real property rather than the full face of the note, allocate both taxes expressly in the purchase agreement at the LOI stage, and coordinate the tax, usury, and security terms as one package. Do that and the financing closes on a number everyone already agreed to; skip it and a four- or five-figure tax surprises the parties at the exact moment the wire is supposed to go out.
