Interest is assessed on the amount of taxes or fees due that was not paid on time. This includes late or underpayments of taxes or fees, and collection allowances (credits) that have been reduced due to underpayments of tax or disallowed because the return was filed late. A floating rate of interest applies. Florida's interest rate is updated twice a year, on January 1 and July 1. Current and past year's interest rates are published in Tax Information Publications (TIPs).

• The floating rate of interest remains at 7% for July 1, 2021 through December 31, 2021. Read more in TIP #21ADM-01 .
• The floating rate of interest is 7% for January 1, 2021 through June 30, 2021. Read more in TIP #20ADM-02 .

To calculate interest due with your tax return:

1. Get the daily interest rate factor(s) for the filing period(s) from the appropriate Tax Information Publication.
2. Calculate the number of days your return is late by counting the number of days from the “late after” date on the return through the date the return and payment are postmarked by the U.S. Postal Service or hand-delivered to the Florida Department of Revenue. Include the day the return and payment are postmarked or hand-delivered when calculating the number of days late.
3. Multiply the amount of tax due by the number of days late and then by the appropriate daily interest rate factor(s).

Example 1: A taxpayer owed $1,000 with his November 2013 Florida sales and use tax return (due 12/20/13). The taxpayer filed the return and paid the tax due on March 10, 2014. The return and payment are 80 days late and the daily interest rate for December 2013 to March 2014 was used. The interest amount due is computed as follows:

Example 2: A taxpayer owed $5,000 with their September 2009 Florida sales and use tax return (due 10/20/09). The taxpayer filed the return and paid the tax on February 10, 2010. The return and payment are 113 days late. Two different daily interest rate factors must be used in the calculation because the interest rate changed on January 1, 2010. For the period 10/20/09 to 12/31/09 the daily interest rate is .000219178 and for the period 1/1/10 to 2/10/10 the daily interest rate is .000191781. The interest amount due is computed as follows:

Municipalities and charter counties collect municipal public service tax (MPST) and report the tax rates to the Florida Department of Revenue. You can search the Department's MPST database or download a spreadsheet containing all MPST rates .

When a new employer becomes liable for the tax, the rate is 2.7% (.0270) and remains at that rate until the employer has reported for 10 quarters (11 quarters in some cases). At that time, a tax rate will be calculated using the employment record and the rating factors, which are built into the Reemployment Assistance Program Law. Rate notices are mailed to all contributing employers each year in December. An employer may appeal the tax rate within 20 days from the date of notification (date printed on the Reemployment Tax Rate Notice (Form RT-20). The maximum tax rate allowed by law is 5.4% (.0540), except for employers participating in the Short Time Compensation Program. Visit the Department's Reemployment Tax webpage for more information.

Sales and Use Tax and Discretionary Sales Surtax Rates

Sales tax and discretionary sales surtax are calculated on each taxable transaction.

Florida's general sales and use tax rate is 6% with the following exceptions: 4% on amusement machine receipts, 5.5% on the lease or license of commercial real property, and 6.95% on electricity.

Discretionary sales surtax (also called county tax) is imposed by many Florida counties and applies to most transactions subject to sales tax. The Florida Department of Revenue collects both taxes and distributes the surtax back to the counties. The discretionary sales surtax rate depends on the county. To compute the sales tax rate for each county, add the local option surtax rate to the general sales tax rate. The Discretionary Sales Surtax Information (Form DR-15DSS) lists the counties and their rates. The History of Local and Current Sales Tax Rates lists the counties and their historical local tax rates.

Effective July 1, 2021, businesses that collect and remit sales and use taxes to the Florida Department of Revenue must use a rounding algorithm when calculating the sales tax due on a transaction. Using this algorithm, the computation of the tax must be carried to the third decimal place; if the third decimal place is greater than 4, the tax must be rounded up to the next cent.

Businesses may apply the rounding algorithm to the aggregate tax amount computed on all taxable items on an invoice or to the taxable amount on each individual item on the invoice. Use of the rounding algorithm takes effect July 1, 2021, and businesses have until September 30, 2021 to update their point-of-sale systems.

For additional information on rounding, review Tax Information Publication (TIP) #21A01-02, “Rounding to Replace ‘Bracket System’ in Calculation of Sales and Use Taxes.”

Any person making taxable sales in Florida must separately state Florida sales tax on each customer’s invoice, sales slip, receipt, billing, or other evidence of sale. The sales tax and discretionary sales surtax may be shown as one total, or the sales tax and surtax may be shown separately.

Effective tax rates and rate divisors may be used by certain industries when it is impractical to separately state Florida sales tax on an invoice, sales slips, receipt, billing, or other evidence of a sale. These industry specific effective tax rates and rate divisors, and instructions for computing sales tax and discretionary sales surtax are available in the following brochures:

• Sales and Use Tax on Alcoholic Beverages (GT-800046 )
• Sales and Use Tax on Amusement Machines (GT-800020 )
• Sales and Use Tax on Concession Stands (GT-800003 )
• Sales and Use Tax on Vending Machines (GT-800041 )

If a prepaid wireless device is sold with prepaid wireless service of 10 minutes or less, or for $5 or less, the seller may elect not to apply the prepaid wireless E911 fee to the sale.

The E911 Board may adjust the rate of the fee, if necessary, to ensure full cost recovery or prevent over-recovery of costs incurred in providing E911 service. Any rate change will be posted to the Department's website. A written notice for each fee rate change will be issued to sellers at least 90 days before the effective date of the change.
