Forms to use BT401 Quarterly Tax Return of Sales and Use Tax
Before we begin The goal of the BT-401 form is to calculate sales tax and then divide it into the proper categories.

The basic 7.25% state sales tax is actually three state required taxes: 6% state sales tax, ¼% county tax, and 1% local tax.

In addition, if you conducted business in any other county or city that voted to increase its sales tax beyond 7.25%, there are one or more district taxes with tax rates ranging from .0125% to .5%

How often Usually a quarterly payment and reporting requirement
Due date Usually one month after calendar quarter-end:April 30, July 31, October 31, January 31. Some businesses complete this form annually, others monthly.

Now: District taxes
So far, you've accounted for a 7.25% sales tax. The next step is to calculate the district sales tax. To do that you need to determine where your business locations were during the last quarter. Your business locations include any county where:
  • Any part of your business is located (including storage or showroom);
  • A representative, agent, salesman, canvasser, or solicitor operates; or
  • Your business receives income from rentals or leases.
List the counties where your business operates (see Collecting Sales Tax). Record the county sales tax next to the name.
  • If none of the counties had more than 7.25% sales tax, line 18 should be 0. Skip the next section and go to line 19.
  • If any of the counties had more than 7.25%, you must complete the Schedule A.
Sch. A
LineWhat to enter
A-1Same as line 16 on the front of form BT-401.
A-2Sales made outside and delivered outside the special tax districts shown.
A-3Sales made from these districts, but delivered outside the special tax districts.
A-4Total special district sales which must be allocated: A-1 minus A-2 minus A-3.

Now, see if any counties where you conduct business are listed on the first column. You only need to include sales to those counties on this page.

LineWhat to enter
A-5Allocate the sales you reported in line A-4 above to the various districts shown in the first column. If any area has 8% or more sales tax, you must list the same sale on two lines. Therefore, the total sales you report in column A-5 may be greater than what you reported on line A-4.
A-6,70, unless you had any adjustments on line 10 (on the front of BT-401) for
  • Bad debts, cash discounts, returned merchandise, from sales made in special tax districts OR
  • If you had taxable purchases made in special tax districts where your supplier failed to collect the district's special tax OR
  • You had fix price contract sales where the contract was made prior to the effective date of the special tax district.
Please see the form's instructions if any of these apply.
