Key Biscayne, FL Tax Landscape
Tax Preparation in Key Biscayne, FL is shaped by two things: the local industry mix and the state tax environment. Because Florida levies no state income tax on individuals, planning shifts to federal work and to state-level obligations that do apply: sales and use tax, and the tangible personal property tax on business assets. The Key Biscayne business base skews toward real estate, finance, professional services, and we calibrate our work, entity structure, quarterly planning, year-end moves, to those revenue patterns. With 1,200+ businesses across Miami-Dade County, Key Biscayne operators need an advisor who understands both the federal playbook and the FL-specific rules. WAYG's subscription model, bookkeeping, payroll, business tax strategy, and CFO-level advisory under one flat monthly price, is built for Key Biscayne owners who want proactive planning instead of once-a-year filing.
Local context: Because Florida levies no state income tax on individuals, planning shifts to federal work and to state-level obligations that do apply: sales and use tax, and the tangible personal property tax on business assets. On the ground in Key Biscayne, that translates into specific moves, entity structure, FL residency planning, multi-jurisdiction sales tax (where it applies), and coordination with your local attorney and banker.

What businesses in Key Biscayne actually charge
Miami-Dade County adds a 1% discretionary surtax on top of the state rate. That surtax only reaches the first $5,000 of a single item of tangible personal property. The state tax reaches the whole amount.
$40,000 of equipment bought in Key Biscayne
- Florida state tax, 6% of $40,000
- $2,400
- Miami-Dade County surtax, 1% of the first $5,000
- $50
- Total tax
- $2,450
A generic calculator applies 7% to the whole $40,000 and answers $2,800. It is wrong by $350, because the surtax stops after the first $5,000.
Across the county line
The same $40,000 purchase, delivered on the other side of the county line.

Miami-Dade County, here · 1%$2,450$50 surtax
-
Monroe County · 1.5%$2,475$25 more
-
Collier County · no surtax$2,400$50 less
Broward County charges the same 1% surtax, so delivering across that line does not change the number.
Rates from Florida Department of Revenue Form DR-15DSS for 2026, under Fla. Stat. 212.054 and 212.055. The Department republishes the table every November, so check the January rate before you bill into a new year.
What this does not model: motor vehicles, where the surtax follows the county the buyer lives in rather than where the sale happens; use tax on purchases made out of state; and the separate rates on commercial rent and electricity. The $5,000 cap also does not reach admissions, transient rentals, prepaid calling arrangements, or services, which are surtaxed on the full amount.
This is an estimate from the figures shown. It is not tax advice and not a promise of a result.
What business equipment costs in Key Biscayne
Sales surtax is set by the county, so all of Miami-Dade County shares one rate. Tax on business equipment does not work that way. It is set by the taxing district, and a municipality is its own district, which is why Key Biscayne has its own number rather than the county's.
$120,000 of equipment bought across six years
- Assessed value after indexing and depreciation
- $81,616
- Less the $25,000 exemption, Fla. Stat. 196.183
- -$25,000
- Taxable value, at 15.5108 mills
- $56,616
- Estimated annual tax
- $878.16
The $25,000 exemption is worth $387.77 a year at this rate, and it is conditional. It does not apply in any year the return is not timely filed. A business that never files loses the exemption and takes a 25% penalty on top, which is $1,582.41 instead of $878.16.

Millage from Miami-Dade County Property Appraiser, 2025 Adopted Millage Rates chart, under Fla. Stat. 200.065. Assessed value computed with the Florida Department of Revenue's 2026 Equipment Index Factors and Untrended Depreciation Schedule. Exemption under Fla. Stat. 196.183. Form DR-405 is due April 1.
2025 is the most recent certified year. Each taxing authority adopts its 2026 millage at public hearings in September, so check the rate before you budget the new year.
What this does not model: a county's own depreciation table, which the Department of Revenue lets it adopt in place of the state schedule; equipment condition, which an appraiser can adjust for; inventory held for resale, which is exempt; licensed vehicles, which are taxed through the tag; and the non ad valorem fees on the same bill, such as fire or solid waste, which are flat charges rather than millage.
This is an estimate from the figures shown. The property appraiser sets the assessed value and their number is the one that counts. It is not tax advice and not a promise of a result.
What a short term rental in Key Biscayne collects
Florida taxes any accommodation rented for six months or less. In Key Biscayne that is three separate taxes on the same night, and they do not all go to the same place.
4 nights at $350 in Key Biscayne
- Rental charge
- $1,400
- Total tax
- $182
- Guest pays
- $1,582
Where each part goes
Two returns, to two separate agencies, on the same night's rent. Filing the local tax on the DR-15 sends it to the wrong place and leaves the county's return unfiled.
-
Florida Department of Revenue, on Form DR-15, Line D$98

Miami-Dade County Department of Regulatory and Economic Resources, Business Section$84
Convention Development Tax, 3% and Tourist Development Tax, 2% and Professional Sports Facilities Franchise Tax, 1%
The line inside Miami-Dade
Key Biscayne pays the rest of county rate, 6%. Miami Beach does not: it is 7% there, plus a separate return to the City of Miami Beach. Buy across the bay and both the number and the number of returns change.
Rates from Florida Department of Revenue Form DR-15TDT R. 03/25, under Fla. Stat. 125.0104 (tourist development tax); Fla. Stat. 125.0108 (tourist impact tax); Fla. Stat. 212.0305 (convention development tax); Ch. 67-930, Laws of Florida, as amended by Chs. 82-142, 83-363, 93-286 and 94-344 (municipal resort tax). The state tax is charged under Fla. Stat. 212.03; Rule 12A-1.061, F.A.C.. Confirmed 2026-08-30.
If the local option transient rental tax is collected by the county, contact that county to verify the tax rate. Not all counties notify the Department of changes in their local option transient rental tax rate.
What this does not model: whether a cleaning or resort fee forms part of the rental charge, which Rule 12A-1.061, F.A.C. governs; the exemptions for a written lease longer than six months, for a full time student, and for active duty military; the collection allowance for a timely electronic filing and payment; and local registration and short term rental ordinances, which are not taxes and which several Florida cities enforce hard.
This is an estimate from the figures shown. It is not tax advice and not a promise of a result.
What the IRS lets a household in Key Biscayne live on
If you owe and cannot pay in full, the IRS does not start by asking what you spend. It starts with its own tables. For a household of 2 with one vehicle in Miami-Dade County, those tables come to $5,770 a month.
- Food, clothing, personal care, health care and the vehicle paymentthe same figure in all 50 states
- $2,441
- Housing and utilities, $2,906, plus running the car, $423Miami-Dade County · Miami metro
- $3,329
$3,329 of that figure, 58%, is decided by your county. The other $2,441 is national and does not move when you do.
One thing almost nobody says out loud: the IRS publishes the housing figure by county, not by city. Every address in Miami-Dade County is allowed the same $2,906, and there is no separate figure for Key Biscayne or for anywhere else inside the county. Where a city spans more than one county, the allowance changes at the county line and not at the city line. What does change from one household to the next is income, and that is the half that decides the answer.
Across the county line
The same household of 2 with one vehicle, run in another county. The bar measures only the local part, because that is the only part that moves.

IRS Collection Financial Standards, effective June 29, 2026, under IRC 7122(d)(2)(A); IRM 5.15.1.8, National Standards. The county housing figure comes from IRS Local Standards: Housing and Utilities. The IRS republishes these tables periodically, so check the date before you lean on the number.
What this does not model: assets of any kind, and in a collection case assets count as much as income; the lesser of rule, since the figure shown is the ceiling; any further operating allowance for an older or high mileage vehicle; a third vehicle; income and FICA withholding, which is allowed in the actual amount; and state or local tax debt.
This is an estimate from the figures shown. It is not tax advice, it is not a filing, and no one can promise you a result with the IRS.
