FLORIDA SALES TAX - COUNTERTOP COMPANIES: THE COMPLETE GUIDE

If you own a Florida countertop fabrication and installation company, Florida sales and use tax just make be the complicated tax issue you had no idea your business has problems with — and not paying attention to the issue could result in six figure assessment on audit. The Florida Department of Revenue (FL DOR) has been aggressively targeting fabrication and installation companies, including countertop contractors, and the average assessment in these audits exceeds $100,000. The rules are not intuitive. Industry practice is frequently wrong. And the misconceptions that get countertop companies into trouble are remarkably consistent from one audit to the next.

This article is the comprehensive guide to Florida sales and use tax for countertop companies. It covers every major compliance area — what you charge customers, what you owe on your materials, how fabrication labor is taxed, and what happens when those rules are applied incorrectly. It is written by James H Sutton, Jr. a Florida CPA and attorney at the Law Offices of Moffa, Sutton & Donnini, P.A. who has represented countertop companies, cabinet makers, and other fabrication/installation contractors in Florida sales tax audits for more 15 years.

THE FOUNDATIONAL RULE: COUNTERTOP INSTALLATION IS A REAL PROPERTY CONTRACT

The starting point for every Florida sales tax analysis involving a countertop company is the nature of the transaction. When a countertop contractor fabricates a slab of granite, quartz, or marble and installs it into a kitchen or bathroom, that transaction is not a sale of tangible personal property. It is a real property improvement contract.

Under Florida Administrative Code Rule 12A-1.051, a real property contractor is defined as someone who supplies and affixes or installs goods that become permanent part of real property. Countertops, once installed, become a permanent fixture of the structure. So, they are real property improvements under Florida sales tax law.

This foundational classification has two major consequences that run counter to what most countertop contractors believe:

First, you do not charge sales tax to your customer on the installed countertop. The entire invoice to your customer — materials, fabrication, edgework, cutouts, and installation — is outside the scope of Florida sales tax. You are not selling tangible personal property; you are improving real property. A customer who presents a resale certificate or tax-exempt certificate cannot avoid tax by doing so because there is no tax to avoid — the transaction was never taxable in the first place.

Second, and critically, you are treated as the end consumer of every material that goes into the project. Because you are not reselling the countertop slab to the customer, you are the final user of the materials. That means you owe Florida sales or use tax on everything you purchase for the project — the stone, the adhesives, the sink cutout blades, the edge profiling supplies, the seam materials, the silicone, and anything else consumed or incorporated into the job.

This two-part rule — no tax to customers, but tax owed on materials — is ½ of the foundation of Florida sales tax compliance for countertop companies. The second ½ of that equation is where the most expensive mistakes occur – Fabrication Labor.

FABRICATION LABOR IS SUBJECT TO SALES TAX:

Materials are only one part of the tax equation for a countertop company. The other is shop fabrication labor, and it is consistently the largest source of audit assessments in this industry.

Under Rule 12A-1.051 and the related fabrication cost rules, a real property contractor who fabricates items at its shop or plant — rather than purchasing finished goods — owes use tax on the fabricated cost of those items. Fabricated cost includes both the cost of the materials incorporated into the fabricated item and the direct labor used to produce the counter top.

For a countertop company, this means that every hour your shop employees spend cutting slabs, profiling edges, cutting sink holes, polishing, and otherwise processing the stone before it leaves for the job site generates a taxable cost. The cost of that labor — combined with the cost of the materials — is the fabricated cost, and use tax is owed on the full fabricated cost. Whenever your team is in the field, measuring before manufacturing or installing counter tops after manufacturing, the cost of that labor is not subject to use tax.

Most countertop companies we encounter in audit situations have been paying tax only on the materials they purchase, treating fabrication labor as non-taxable. This is incorrect, and auditors know it. The fabrication labor issue alone frequently accounts for the majority of an audit assessment.

There is an important distinction between fabrication and installation. Fabrication is any work performed at your shop to prepare the material before it goes to the job site — cutting, edging, polishing, and templating done off-site. Installation is the work performed at the job site — setting, seaming, and securing the countertop in place. Only fabrication generates a use tax obligation. Installation labor does not. Keeping those costs clearly separated in your records is critical to minimizing your exposure if audited.

WHAT MATERIALS ARE TAXABLE — AND WHEN

The general rule is that a countertop contractor owes tax on all materials that become part of the finished countertop or are consumed during the fabrication and installation process. That includes:

Stone slabs (granite, quartz, marble, quartzite, porcelain) purchased for fabrication
Adhesives and epoxies used for seaming or setting
Blades, bits, and polishing pads consumed during fabrication
Silicone and caulk used during installation
Undermount clip systems and brackets
Shop supplies consumed in the fabrication process

If a countertop company purchases these materials from a Florida-based supplier, the supplier should collect Florida sales tax at the point of purchase. If materials are purchased from an out-of-state vendor who does not collect Florida sales tax — a common situation with stone distributors — the countertop company owes Florida use tax on those purchases at the same 6% rate (plus applicable local surtax).

Use tax on out-of-state purchases is one of the most consistently underreported obligations in the countertop industry, and it is one of the first things an auditor examines. The auditor will compare your accounts payable records against your use tax accruals and filings, and any gap creates an immediate assessment.

THE TRAP - RETAIL SALE PLUS INSTALLATION EXCEPTION

I’ve been representing the construction industry for a long time (actually passed the GC exam more than 20 years ago), and I’ve seen a lot of horror stories of people misunderstanding Florida sales tax law with very expensive consequences. One such misunderstanding that seems to have found its way into the counter top industry is that Florida law has different sales tax treatment for what is known as retail sale plus installation contract, governed by Rule 12A-1.051(3)(d), F.A.C. The problem is, I have never seen a situation where a taxpayer in the counter top industry qualifies under the retail sale plus installation rule.

To qualify as a retail sale plus installation contract, the counter top company would to have a contract (the day you are hired) that specifically described and itemized each and every item used in the job, each of those items must be at a specific price, the labor has to be separately prices, AND the risk of loss must pass to the customer at the time the materials hit the job site. If structured correctly, the contractor under a retail sale plus installation contract is not treated as the end consumer of the materials — instead, the customer pays sales tax on the materials, and the installation labor is not taxable. I’ve never seen a contract for counter tops that would meet all these requirements. Besides the lunacy of listing and separately pricing exactly how much adhesive, shim, and ounces of polish you are going to use, no customer is going to agree to have the risk of loss pass to them before the counter tops are installed. It just doesn’t happen in the real world. So, can any counter top installation contract every qualify for “retail sale plus installation” treatment? Probably not.

Most countertop companies operate under lump-sum or cost-plus contracts and are properly classified as real property contractors. The retail sale plus installation option is technically available, but for all practical purposes is not realistic.

THE $5,000 SURTAX CAP: A REFUND OPPORTUNITY MANY COMPANIES MISS

Florida's discretionary county surtax (local option sales tax) is capped at $5,000 per transaction — but the rules for applying this cap in the fabrication context are frequently overlooked by both taxpayers and auditors.

Under Rule 12A-15.008, F.A.C., a manufacturer or fabricator who installs goods into real property as part of a real property contract is entitled to apply the $5,000 surtax cap to the fabricated cost of goods incorporated into each specific contract. This means that if a countertop company fabricates a countertop package for a single project with a fabricated cost exceeding $5,000, the county surtax is capped at $5,000 × the surtax rate for the full fabricated cost of that project — not charged per individual purchase.

Many countertop companies overpay surtax because they pay it transaction by transaction on each slab purchase rather than applying the per-project cap. If your company has been paying surtax on each material purchase without applying the bulk sale/project cap, there may be a refund opportunity worth pursuing. See our article on the $5,000 surtax cap for a detailed analysis.

WHAT HAPPENS DURING A FLORIDA SALES TAX AUDIT OF A COUNTERTOP COMPANY

The FL DOR targets countertop and fabrication companies because the industry is reliably non-compliant and assessments are predictably large. Most of the time, the auditors have outside information that implies the company is doing something wrong. When an auditor arrives, the examination will focus on the following:

Purchases audit. The auditor will review all material purchases and compare them against sales and use tax paid. Any purchases for which no Florida sales or use tax was remitted — including out-of-state purchases — generate an immediate assessment if you can’t prove sales tax was already paid.

Fabrication labor. The auditor will attempt to reconstruct your fabricated cost for the audit period using payroll records, job costing records, and direct labor allocations. If you have not been accruing use tax on fabrication labor, the assessment on this item alone is typically substantial. WARNING – a lazy auditor might try to use “Cost of Goods Sold” on your federal tax return as the basis of the assessment for materials and labor used for fabrication, but that number is always inflated if for any other reason because field installation labor would be included in that number.

Customer invoices. If the auditor finds that you have been charging sales tax to customers on installed countertop jobs, those collections are themselves a problem — the FL DOR takes the position that tax collected on a non-taxable transaction must still be remitted, and that you still owe use tax on materials and labor without taking into account the taxes you already remitted. This type of double taxation happens too often, but we can usually stop it from happening with a higher level of challenge after the audit.

Subcontractors. If you are a prime contractor and your subcontractor is the company providing installed counter tops, then that subcontractor is the real property improvement contractor that owes tax, not you. I’ve seen auditors misunderstand this concept often, which is one more thing left to fight after the audit.

FREQUENTLY ASKED QUESTIONS: FLORIDA SALES TAX FOR COUNTERTOP COMPANIES

Q: Should I charge my customers sales tax on a countertop installation job?

A: No. If the countertop is being permanently installed into a structure, the contract is a real property improvement contract. You do not charge sales tax to your customer on the total invoice. Florida Administrative Code Rule 12A-1.051 governs this classification.

Q: Should I pay sales tax when I buy granite or quartz slabs from my supplier?

A: Yes. As a real property contractor, you are the end consumer of the materials. You should pay Florida sales tax to your Florida suppliers at the time of purchase on your purchase price (not price charged to your customer). If you purchase from out-of-state suppliers who do not collect Florida tax, you owe Florida use tax on those purchases and must self-accrue and remit it directly to the FL DOR.

Q: Is the labor my shop employees perform on the stone taxable?

A: Yes. Fabrication labor — any work performed at your shop to prepare the stone before it goes to the job site — is included in the "fabricated cost" subject to use tax under Rule 12A-1.051. Installation labor performed at the job site is not taxable.

Q: What if my customer presents a resale certificate to avoid sales tax on the countertop?

A: A resale certificate does not apply to a real property improvement contract. The customer's resale or exemption certificate is irrelevant because no sales tax is being charged in the first place. Accepting a resale certificate on a real property contract does not change your tax obligations as the contractor. This is a very important clarification that costs a lot of counter top companies tax when they get audited!

Q: Can I use a retail sale plus installation contract to shift the tax to my customer?

A: In limited circumstances, yes — but it requires strict upfront documentation including itemized material pricing before work begins. The structure cannot be applied retroactively and is subject to challenge if the documentation does not meet the requirements of Rule 12A-1.051(3)(d).

Q: What is the penalty for getting this wrong?

A: Florida's standard audit penalty ranges from 10% to 50% of the tax assessed, depending on whether the error was willful. Interest currently accrues at 11% per year on unpaid tax. Multi-year audit assessments on countertop companies frequently exceed $100,000 once tax, interest, and penalties are combined. But, we can often get the penalties compromised if we can get a timely challenge filed.

Q: If I discover my company has a compliance problem, what should I do?

A: Contact a Florida sales tax attorney immediately to evaluate whether the Florida Voluntary Disclosure Program is available to you. Voluntary disclosure limits the look-back period to three years, waives most penalties, and eliminates criminal exposure — but it is only available before the FL DOR contacts you.
