Florida’s Form DR-15, the sales and use tax return, is due on the 20th of the month after each reporting period, with your filing frequency (monthly, quarterly, twice a year, or once a year) assigned by the Department based on how much tax you collect. A late return brings a penalty of 10% of the tax due, with a $50 minimum, plus interest, and you must file even when you had no sales. Businesses that paid $5,000 or more in tax in the prior year must file and pay electronically.
The DR-15 looks like a routine monthly chore, and for a business with clean records it is. But the deadlines are firm, the penalties for missing them add up, and a handful of small, repeatable errors can quietly inflate what you owe until an audit brings it to the surface. If your business has nexus in Florida and collects sales tax, the DR-15 is how you report and remit it. For the wider context, see our complete guide to Florida sales and use tax.
The DR-15 at a Glance
- The DR-15 is Florida’s combined sales and use tax return.
- It is due on the 20th of the month after each reporting period.
- Your filing frequency is assigned by the Department, not chosen by you.
- A return is required even for a period with no sales.
- Filing late costs 10% of the tax due, with a $50 minimum, plus interest.
When the DR-15 Is Due
Every DR-15 is due on the 20th of the month following the period it covers. A monthly filer reporting January files by February 20; a quarterly filer reporting the first quarter files by April 20. If the 20th falls on a weekend or a holiday, the deadline moves to the next business day.
There is a separate trap for electronic filers. When you pay electronically, you generally have to initiate the payment by 5 p.m. Eastern on the business day before the 20th so the funds settle on time. Treating the 20th itself as the cutoff for an electronic payment is a common way to end up a day late. Missing that settlement window, even by a single day, is treated as a late payment that draws the full penalty.
What the DR-15 Reports
The DR-15 is a single return that captures more than the sales tax you collected. On it you report your gross sales, the portion that was exempt, and the resulting taxable amount, along with the state tax and the discretionary surtax due. It also has a line for taxable purchases, where you self-report use tax on items you bought without paying Florida tax at the time. After lawful deductions and the collection allowance, the form nets to the amount you actually owe.
Because so much flows through one return, an error in any single figure, the exempt portion, the surtax, or the use tax line, changes the bottom line. That is why the small errors below matter: they do not stay contained to one box on the form.
Your Filing Frequency
You do not choose how often you file. When you register as a dealer, the Department assigns a frequency based on how much tax you collect, and it can change as your volume grows or shrinks:
- Monthly for businesses collecting more than $1,000 in tax a year.
- Quarterly for $501 to $1,000 a year.
- Twice a year for $101 to $500 a year.
- Once a year for $100 or less a year.
The frequency is not permanent. As your sales grow, the Department can move you to more frequent filing, and a business that consistently under-files relative to its volume can draw scrutiny. If you operate more than one Florida location, each one may carry its own filing obligation.
On Time vs Late: Penalties and the Collection Allowance
Filing on time does more than avoid a penalty; it also preserves a small benefit. Filing late does the opposite.
| Filing on time | Filing late | |
| What it means | Return and payment in by the 20th | Return or payment after the deadline |
| Measurement (the trigger) | Filed and paid by the 20th | Filed or paid after the 20th |
| The cost | No penalty | 10% penalty ($50 minimum) plus interest |
| Collection allowance | You keep 2.5% of the first $1,200 | You forfeit the allowance |
The collection allowance is 2.5% of the first $1,200 of tax due, up to $30 per reporting location, but you only keep it by filing and paying on time. A late return forfeits it and adds the penalty and interest on top. Interest accrues monthly at a floating rate the state adjusts periodically, so an unpaid balance keeps growing until it is cleared.
The Zero Return Rule
One rule catches businesses off guard more than any other: you must file a DR-15 for every reporting period, even when you had no sales and owe no tax. This is the zero return. Skipping it is itself a filing failure, and a string of unfiled periods, even empty ones, can flag your account and complicate things later when you try to get current. If you have already missed several zero returns, the fix is to file the outstanding periods, and the longer the gap runs, the harder it is to get the account back in good standing.
Common DR-15 Errors
Most DR-15 trouble comes from small, repeatable errors rather than one large mistake. These are the ones that quietly inflate liability:
- Applying the wrong county rate, since Florida is destination-based and the rate follows the buyer’s county, not yours.
- Mishandling the $5,000 surtax cap, which limits county surtax to the first $5,000 of a single tangible item.
- Skipping the zero return in a period with no sales.
- Filing or paying late, which forfeits the collection allowance and adds penalty and interest.
- Leaving use tax off the return on out-of-state and online purchases, a top audit finding.
- Missing the electronic payment deadline, which falls the business day before the 20th.
How Small Errors Become an Assessment
The danger with these errors is that they repeat. A county-rate mistake or a mishandled surtax cap is not a one-time miss; it is built into how the business files, so the same shortfall shows up period after period. By the time the Department reviews the returns in a sales tax audit, the gap has compounded across months or years.
At that point the Department assesses the cumulative under-reported tax, adds penalties, and applies interest back to each period. If you have fallen behind on filing, or suspect your returns carry a recurring error, a Business CPA Tax Resolution Case Analysis reviews the back-filing and the exposure and lays out the cleanest way to resolve it, rather than letting it surface in an audit on the Department’s timeline.
For official guidance, the Florida Department of Revenue’s sales and use tax pages and its sales and use tax brochure cover the DR-15, due dates, and filing rules, though neither replaces advice on your own situation.
