Florida sales tax for contractors depends on the type of job. On a real property job, a contractor usually pays tax on the materials but does not charge the customer. Installing tangible personal property is different, however. There, the Florida Department of Revenue says to charge tax on the total charge. This is general information, not tax advice.
This guide uses the Department’s own publications. First, it explains how the rules sort jobs, what contractors pay tax on, and who must register. It also covers what to do about past mistakes. Rules change, so confirm your situation with a CPA or the Department.
Do Florida Contractors Charge Sales Tax on Labor?
It depends on the type of job, because each group of jobs gets its own treatment. The Department’s guide for building contractors sorts the jobs into those groups.
| Type of Job | What the Contractor Does | Examples From the Department |
| Lump sum, cost plus, fixed fee, guaranteed price, or time and materials job | Pays sales tax on materials to suppliers and does not charge the customer tax | Roofing, tile, electrical system, landscaping |
| Installing fixtures | Pays tax on the fixtures and installation materials and collects no tax from the customer | Central air-conditioning unit, furnace, built-in cabinets, wired lighting |
| Retail sale plus installation contract | Buys materials tax-exempt for resale and charges the customer tax on the materials | Materials itemized and priced in the contract before work begins, with the customer taking title |
| Installing tangible personal property | Collects sales tax on the total charge | Window air-conditioning unit, free-standing household appliance |
So for real property work, the answer is usually no. But when you install tangible personal property, the answer is yes. Itemizing does not change the first case. A November 2025 technical assistance advisement makes the point. In it, the Department said a lump sum contractor should not charge the customer tax, whether or not the invoice itemizes materials and labor.
How Does Florida Tell Real Property From Tangible Personal Property?
Section 212.06(14), Florida Statutes, defines improvements to real property. It lists building, erecting, constructing, altering, improving, repairing, and maintaining real property. That same section also defines fixtures. Those are items that become permanently attached to the realty, although they keep their identity as accessories. Tangible personal property is different. You can see, weigh, or touch it, but it is not permanently attached.
Method of installation matters, so the Department gives a mailbox as its example. A mailbox bricked into a post beside the road is a real property improvement. But a mailbox screwed to the house or to a wooden post stays tangible personal property. For fixtures, then, the Department tells contractors to consider four things: the installation agreement, the method of attachment, the intent of the parties, and permits and licensing.
Appliances follow the same logic. According to the Department’s construction and repairs guide, a hard-wired residential appliance becomes real property. But a free-standing one stays tangible personal property.
How Does Florida Sales Tax for Contractors Treat Repairs?
First, the statute counts repairing and maintaining real property as improvements to real property. So those repairs follow the real property rules above. Repairs to tangible personal property work differently. When you repair it, the Department says that parts and labor are generally taxable.
There is a narrow exception, though. A repair that needs only labor is not taxable. However, the repairer must document that no parts were attached to the item. That same guide also warns that tax applies even when the parts are free.
Are Maintenance Agreements Taxable?
Maintenance or service warranty contracts on taxable tangible personal property are taxable, the Department says. But that does not include contracts on property that becomes part of real property. So the answer depends on what the agreement covers.
Based on that wording, then, a plan on a free-standing appliance may be treated differently from a plan on a built-in fixture. Ask your CPA to review each type of agreement you sell, because the facts decide the result.
What Does Florida Sales Tax for Contractors Cover on Materials?
On lump sum and similar jobs, the contractor is the final consumer, so you pay sales tax on materials when you buy them. If an out-of-state seller does not charge Florida tax, you owe use tax instead. Florida’s state rate is six percent, but most counties also add a discretionary sales surtax. For contractors, the Department says the surtax applies to the first $5,000 of the sales amount on materials and supplies.
Resale certificates need care, because misuse creates use tax. The Department says contractors on lump sum, cost plus, and similar contracts may not buy materials tax-exempt for those jobs. If you buy goods for resale and later use them, you then owe use tax on them. Also, contractors who fabricate items for their own jobs owe use tax on the fabrication cost. But fabrication labor at the job site is not part of that cost.
Who Must Register to Collect Florida Sales Tax?
Not every contractor must register. According to the Department, three groups must. One sells tangible personal property. Another does real property contracts and also sells such property at retail. A third fabricates items and owes use tax on the fabrication cost.
Deadlines matter once you register. Returns and payments are due the first day of the month after each reporting period. They are late after the 20th. A late filing or payment can therefore draw a penalty of 10 percent of the tax owed, with a $50 minimum. Also, if you paid $5,000 or more in sales and use tax in the prior state fiscal year, you must file and pay electronically.
What Mistakes Do Florida Contractors Make Most Often?
Several mistakes come up again and again. First, owners apply one tax treatment to every invoice. Second, they treat a window air-conditioning unit like a central system, but the Department classifies the two differently. Third, they buy materials tax-exempt for a lump sum job, yet the Department says contractors on those contracts may not. Fourth, they assume itemizing labor changes the tax on a lump sum job. Fifth, they treat every maintenance agreement alike. Finally, they skip documentation, even though a labor-only repair requires it.
Audit your invoices for each of these mistakes, because they are the most common problems in Florida sales tax for contractors.
What Should You Do If You Find Past Mistakes?
Do not ignore them, and do not panic. The Department runs a Voluntary Disclosure Program for unpaid or underpaid taxes, including sales and use tax. Its page says that penalty is waived in most cases.
Timing matters, though. Your application must state that the Department has not already contacted you about the liability. So talk to a CPA who knows Florida contractor tax before you apply, because the right path depends on what you found and how far back it goes.
How Do You Apply Florida Sales Tax for Contractors on Every Invoice?
The hard part is not the rule, but applying the right rule to every invoice a technician writes in the field. So build the tax treatment into your job types in the invoicing system. Then no one has to decide on the spot.
Also keep clean records. Tax you pay on materials is usually part of what the materials cost you, so it belongs in job cost. Your CPA can also confirm the treatment.

Frequently Asked Questions
Do Florida contractors charge sales tax on labor?
Usually not on real property work. On lump sum, cost plus, fixed fee, guaranteed price, and time and materials jobs, the contractor pays tax on materials but does not charge the customer. However, when a contractor installs tangible personal property, the Department says to charge tax on the total charge. This is general information, not tax advice.
Does itemizing labor and materials change how a Florida invoice is taxed?
On a lump sum real property job, no. In a November 2025 advisement, the Department said the contractor should not charge the customer tax. That holds whether or not the invoice itemizes charges, so itemizing does not change the result. A retail sale plus installation contract is different, because it has strict requirements. Those include itemized materials priced before work begins.
Is HVAC installation taxed in Florida?
It depends on the equipment. The Department lists central air-conditioning units as fixtures, so the contractor pays tax on materials and does not charge the customer. But a window air-conditioning unit is tangible personal property, so the contractor collects tax on the total charge.
Are maintenance agreements taxable in Florida?
The Department says maintenance or service warranty contracts on taxable tangible personal property are taxable, the Department says. That rule does not include contracts on property that becomes part of real property, so the answer depends on what the agreement covers.
Does a Florida contractor need to register to collect sales tax?
Only in some cases. According to the Department, three groups must register. They are contractors who sell tangible personal property, contractors who do real property contracts and also sell such property at retail, and contractors who fabricate items and owe use tax on the cost.
What is the Florida sales tax rate for contractors?
The state rate is six percent, but most counties add a discretionary sales surtax. For contractors buying materials, the Department says the surtax applies to the first $5,000 of the sales amount.
What should a contractor do about past sales tax mistakes?
Talk to a CPA, and ask about the Department’s Voluntary Disclosure Program. Its page says that penalty is waived in most cases, but you must apply before the Department contacts you about the liability.
Where can a contractor find the official Florida sales tax rules?
The Department publishes guides GT-800007 and GT-800067. Also, the rules appear in Rule 12A-1.051 of the Florida Administrative Code and Section 212.06 of the Florida Statutes. Check the current versions, because rules and forms change.
The Bottom Line
Florida sales tax for contractors comes down to sorting each job correctly. A job is real property work, a fixture installation, a retail sale plus installation contract, or the installation of tangible personal property. Each group treats tax differently, and itemizing an invoice does not change that on a lump sum job.
So build the treatment into your job types and keep your documentation. Review old invoices if you suspect an error. This post is general information, not tax advice, so confirm your situation with a CPA or the Department.
