Sales Tax Filing Deadlines: Texas Dates for Practices
Sales tax filing deadlines in Texas: Comptroller due dates, filing frequency, returns, discounts and penalties, plus the client calendar a practice needs.
What to take away
- Sales tax registration creates a recurring filing, including periods where the client sold nothing.
- Texas sales tax filing deadlines fall on the 20thmonthly, quarterly and yearly reports each have a fixed date set by the Texas Comptroller of Public Accounts (details below).
- The Comptroller tells each new permit holder by letter whether it files monthly or quarterly, so the practice files that letter with the client record.
- Collected tax belongs to the state, not the client, so the practice carries it as a liability.
- Late reports and late payments cost money in Texas, while timely ones earn a small discount.
- Every confirmation is filed with the return that produced it.
Texas Due Dates, Returns and Penalties
For Texas sales tax filing deadlines, follow the Texas Comptroller's due-date schedule: monthly reports are due on the 20th of the month following the reporting month, so the April report is due May 20; quarterly reports are due April 20 for Jan.–March, July 20 for April–June, Oct. 20 for July–Sept., and Jan. 20 for Oct.–Dec.; reports of sales for the previous year are due Jan. 20 for yearly filers. If a due date falls on a Saturday, Sunday or legal holiday, the next working day is the due date. Taxpayers are notified by letter, once their sales tax permit application is approved, whether they will file monthly or quarterly. On top of the state tax, cities, counties, special purpose districts and transit authorities can impose local sales and use tax, so the rate depends on the location. Permitted sales taxpayers can claim a discount on tax timely reported and paid, with an extra discount for those who prepay. A penalty is assessed on each report filed after the due date, a further penalty applies to tax paid late, and it rises once payment is more than 30 days late. Interest on past-due tax begins 61 days after the due date.
The return itself is Form 01-114, the Texas Sales and Use Tax Return, with Form 01-117 as the short form. Put the client's assigned frequency, the form it uses and the next due date on one line of the practice calendar.
Example: one client, four states
A bookkeeping client sold only in its home state for six years. Then it leased a warehouse in a second state, hired a remote controller in a third, and began selling through a marketplace.

Four registrations followed, each with its own rhythm. Two filed monthly, one quarterly, one annually with nothing to report. If one of them is Texas, the dates above apply to it; the other states publish their own schedules.
A registration behaves like a standing appointment. Standing appointments belong in one system, not four client folders.
Building the Registration List at Onboarding
Every state claim starts with a footprint, and state tax deadline differences decide how many dates that footprint creates.
Onboarding Registration Steps
- Map people, property, inventory, customers by state
- Commission written review of obligation states
- Read revenue department page for client's industry
- Register before first sale in required order
Write down where the client has people, property, inventory and customers, and date the document.
A written review of which states have a claim is a defined engagement with a written answer. Scope it as a separate engagement, not as a phone call.
- Map people, property, inventory and customers by state.
- Commission a written review of where the client has an obligation.
- Read the revenue department page written for that client's industry.
- Register before the first sale into the state, in the order the state requires.
The IRS keeps a topic page on state tax filing deadlines and extensions as a state index. The binding date still sits with the agency in each state.
Reconcile Collections Each Filing Period
Collected tax should never sit in the operating account looking like revenue. That habit causes most of the shortfalls found at filing time.
Reconcile Collections Each Period
- Reconcile ledger collections against bank deposits
- Confirm liability matches charged but not remitted
- Check for a state new since last period
- File everywhere open, including nil returns
- Save each confirmation beside its return
Move the money, or flag the balance as a liability in the ledger. If the client's books cannot carry that split, tax preparation cash flow basics cover the two-account method most owners accept.
- Reconcile ledger collections against deposits in the bank.
- Confirm the liability balance matches what was charged and not remitted.
- Check for a state new to the client since the last period.
- File everywhere a registration is open, including nil returns.
- Save each confirmation beside the return that produced it.
A nil return is the cost of an open registration.
Matching Registrations to the Practice Calendar
Six changes reset a client's sales tax position, and each one lands on the calendar as a question.
Matching Registrations to the Calendar
| Change in the client's business | Question the calendar must answer |
|---|---|
| New product or service line | Is it taxed the same way as what the client already sells? |
| New state or marketplace | Does a registration exist, and when is the first return due? |
| New warehouse or fulfillment arrangement | Does inventory held there create a presence? |
| Remote hire | Does that person change the client's position in the state? |
| Customer claims an exemption | Is the documentation valid, and where is it kept? |
| Sales end in a state | Should the registration be closed, and by what date? |
A tracker holds each client's frequency, due dates and proof of filing in one place.
The exemption row deserves a note. Documentation behind a claim of non-liability protects the seller later. Without it, the assessment lands on the client.
Two federal dates anchor the practice year even though none of these filings are federal. The IRS e-file shutdown and availability dates close the return window. Separately, PTIN renewal deadline dates decide who may sign a return at all.
Closing Registrations and Year-End Review
An open registration keeps filing alive after the last sale. At year end, list every registration the client holds and ask which ones still earn their keep.
Reconcile the full year of collections against the full year of filings, state by state. Give the accountant the state list, not only the federal figures.
When a client brings a notice from a period the practice never handled, the client missed tax deadline procedure sets out what to collect before anyone calls the state.
Keep returns, confirmations, exemption documentation and enough sales detail to rebuild a return. Retention periods are a state answer, not a federal one.
Common questions
Do we file a nil return in a state where the client sold nothing?
Yes, while the registration is open. That is why closing registrations the client no longer needs sits on the year-end list.
The client's marketplace says it handles sales tax. Is the practice finished there?
Possibly for sales made through that platform, and possibly not for anything else the client sells. Ask for the marketplace position in writing, then check what it leaves with the client.
What happens when a client collected tax and never filed it?
Take it to a CPA licensed in that state promptly. Voluntary correction is generally treated differently from being found, and the money was never the client's to keep.
Does a remote hire change the client's filing calendar?
It can, because payroll obligations often arrive with the person, and payroll tax cases collects ten of them, from the remote hire to the missed deposit.
