TIP #09A01-07
DATE ISSUED: October 7, 2009


Your total sales and use tax payments for all accounts that have the same Federal Employer Identification Number (FEIN) or Social Security Number (SSN) reached $200,000 for the period of July 1, 2008, through June 30, 2009. Based on this, you are required to make estimated sales tax payments for all accounts (see the enclosed list) beginning with your December 2009 return. This estimated payment requirement applies to the January 2010 through December 2010 collection periods, for all of your sales and use tax accounts listed.

Estimated Payments

You report your first 2010 estimated tax payment(s) on Line 9 of your December 2009 return(s). This will be the estimated tax for January 2010. Monthly sales and use tax returns are due on the 1st day of each month and are late after the 20th day of each month following the collection period. However, if the 20th falls on a Saturday, Sunday, or state or federal holiday, tax returns must be postmarked on the first business day following the 20th. You must initiate your electronic payment on or before Tuesday, January 19, 2010, 5:00 p.m., Eastern Time (ET).

When filing your January 2010 return, you will pay the estimated tax for February 2010 on Line 9 and then subtract the estimated tax previously paid on the December 2009 return (for January 2010) on Line 8. You must continue to make estimated tax payments on each return throughout 2010.

Three Methods for Computing Estimated Tax

The percentage factor for calculating estimated tax is 60%. Your estimated tax liability is based only on Florida sales and use tax due and does not include discretionary sales surtax. Compute your estimated tax liability using one of the following methods:

Note: If you incorrectly calculate or forget to enter your estimated tax, you cannot amend your return.

Method 1 (Averaging)

To use this method you must first calculate 60% of your average sales tax liability for those monthly tax returns for January 2009 through December 2009. Only use months where you reported taxable transactions.

Example: When completing your December 2009 return, you must first calculate your average sales tax liability for the 2009 calendar year. To calculate your average, complete the following steps:

Step 1.    Review all of your 2009 sales tax returns (including December return).

Step 2.    Add together the amounts from Line 7 (minus discretionary sales surtax) for all 2009 returns.

Step 3.    Divide the total of all Line 7 amounts by the number of returns filed with tax due on Line 7. This is your 2009 average sales tax liability.

Step 4.    Multiply your 2009 average sales tax liability by 60%.

Step 5.    Enter the amount determined in Step 4 on Line 9 of your December 2009 return and all returns for 2010 through November. When using this method, you will need to recompute the estimated tax due before filing your December 2010 return.

Method 2 (Same Month in Previous Year)

Calculate 60% of your sales tax collected during the same month of the previous calendar year.

Example: When completing your December 2009 return, multiply the amount on Line 7 of your January 2009 return (less discretionary sales surtax) by 60%. Enter that amount on Line 9.

Method 3 (Next Collection Period)

Calculate 60% of the tax collected for the collection period following this return.

Example: When completing your December 2009 return, your estimated tax liability is 60% of what you will collect (minus discretionary sales surtax) for the January 2010 return. Enter that amount on Line 9. If you are unable to estimate what you will collect (minus discretionary sales surtax) for the January 2010 return, we recommend you use Method 1 or Method 2.

Note: If you correctly calculate your estimated tax using one of the three methods described, you will not be assessed a penalty for underpayment of estimated tax. You are NOT required to use only one method and may choose to use any one of these methods throughout the year.

Consolidated Filing Method

Dealers who operate two or more places of business that report through a central office or location are eligible to file a consolidated return. All consolidated accounts must file and pay electronically. When filing a consolidated return with information for each location, only one electronic initiation and payment is necessary. If you would like to begin filing a consolidated return, please submit an Application for Consolidated Sales and Use Tax Filing Number (Form DR-1CON). After your application is processed, we will issue you a consolidated account number. You will need the consolidated account number before enrolling for e-Services.

Penalty for Underpayment of Estimated Tax

If you underpay your estimated tax, a penalty of 10% is due on the underpaid amount. We will send you a Notice of Additional Tax Due. If you forget to enter your estimated tax, you cannot amend your return.

Penalty Rate for Late Filing

The penalty for late payments of sales and use tax is either 10% of the tax due on your tax return, including discretionary sales surtax, or a minimum of $50, whichever is greater. The $50 minimum penalty applies even if no tax is due.


If your payment is late, you owe interest on the amount due. Florida law provides a floating rate of interest for late payments of taxes and fees due, including discretionary sales surtax. The floating rate of interest is calculated using the formula in section 213.235, Florida Statutes, and is updated on January 1 and July 1 each year. You may obtain interest rates from our Internet site at
