The receipt says 8.25%. The return still has to show which part of that is city and which part is transit.
You are not behind because Addison is confusing. You are staring at one local bucket that should be two. Dallas MTA is a full 1% of the combined rate, the same size as the city tax. A filing that treats both as city tax can still add up and still be wrong.
Addison is in Dallas County. The city tax is 1%. Dallas MTA is 1%. There is no special-purpose district on Addison's line. State sales tax is 6.25%. State, city, and Dallas MTA add to the combined 8.25%. The pieces you can name are the whole rate. Business personal property renditions go to Dallas CAD. The due date to put on the calendar is April 15. Use Dallas CAD's form, and follow that form's instructions for which date controls the property list. The Texas franchise (margin) tax report is due May 15. A no-tax-due threshold exists. The dollar cutoff is not printed on this page. Read the Comptroller's instructions for the report year before you decide the report is short. Texas has no state personal income tax. That fact does not retire the sales-tax return. Sales-tax filers are assigned monthly, quarterly, or yearly by volume. The assignment is on the permit, not on Addison's rate line. The retail-store cleanup site is the fleet page for a counter that collected this mix. The industries page lists the other guides.
Start with a receipt, not with a speech about software. Pick a Tuesday that was ordinary. Lay ten customer tickets on the desk. Each ticket should still show the city. City tax is 1%. Dallas MTA is the other 1%. A report that dumps both into an account named Sales Tax has preserved the customer's total and lost the split. The Comptroller's line for Addison wants the split. A later reviewer who only sees the total will ask which liability is which, and the file will not answer. Now set those tickets beside the return that covers the same days, and beside the bank deposits. The deposit is a bad stand-in for taxable sales. Card fees leave before the money lands. Cash paid out of the drawer never arrives. A gift card sold today is not the same as a shirt sold today. If the only number in the payable account is 'deposits times a rate,' the account is a plug. You cannot file a split you never recorded. Some of the ten tickets will name a different city. They do not get rescued by the fact that the other city also totals 8.25%. Addison's local mix is city 1% plus Dallas MTA 1%. Another city at the same total can be a 2% city tax and no transit at all. Same headline rate, different buckets. Those tickets come off the Addison worksheet. Send the last return you filed, the deposit listing for that same period, and the ten tickets with the city still readable. The first pass does not rebuild the year and does not recode inventory. It marks each Addison ticket as city 1% and Dallas MTA 1%, and it parks every other city on a side list. You get a one-page tie-out: tax collected on Addison tickets, tax that belongs on the Addison lines, and tax that belongs somewhere else. You also get the plug amount, if the payable account was just deposits times a rate. That page comes back before the next due date printed on your permit, so the open return can use the split. You do not need a tidier file than that to ask for the look. You do need the city left on the ticket. The file goes first.
The longer page for a store that rings taxable sales is the retail-store guide.
If the business is a different shape, start from the full list instead of forcing this one.
