Can a retailer switch from reporting sales tax on an accrual basis to a cash basis, and what happens to sales tax already reported under the old method?

Plain-English summary

A company had been reporting Texas sales tax on the accrual basis but was experiencing a large increase in store-charge-card sales, and wanted to switch to a cash basis (remitting tax as customer payments come in) because that would more closely match sales taxes actually collected. Its representative asked whether any special paperwork was required for the switch.

The Comptroller confirmed the switch is permissible with no special forms — but flagged two important mechanics:

1. The change is prospective only. No credit is allowed for tax already remitted under the old (accrual) method. Because the company will have both "tax-paid sales" (made before the conversion) and "tax-due sales" (made after) coexisting during the transition as customer payments come in, it must establish a procedure to correctly track and report both categories. Getting this wrong exposes the company to a tax assessment plus penalty and interest if an audit later finds sales tax wasn't properly reported during the transition.

2. Credit/installment sales interaction. Switching to a cash basis can trigger 34 TAC § 3.302(f), which applies to retailers making installment sales who build the sales tax into the outstanding balance and charge interest on that balance. Those retailers must separately report and remit to the state a portion of the interest collected on the sales-tax portion of the installment balance — on top of the regular sales tax due — using a separate return for the same reporting period as their regular sales tax filings.

What this means for you

Retailers considering an accrual-to-cash switch for sales tax reporting

You can make the switch without special forms, but plan carefully for the transition period — you'll need a clear method for tracking which sales were already tax-reported under the old method versus which are newly tax-due under the new method, since no retroactive credit is available.

Retailers offering installment/credit sales with sales tax included in the balance

If you charge interest on outstanding balances that include the sales tax portion, check whether Rule 3.302(f)'s separate interest-remittance requirement applies to you — it's an additional filing obligation layered on top of your regular sales tax return.

Accountants advising clients on accounting method changes

This letter is a good short reference for the "prospective only, no retroactive credit" rule that generally governs sales tax accounting method changes, plus the installment-sale interest wrinkle that a cash-basis switch can surface.

Common questions

Q: Does a retailer need special forms to switch from accrual to cash basis sales tax reporting?
A: No special forms are required, per this letter.

Q: Is credit available for sales tax already remitted under the accrual method after switching to cash basis?
A: No — the change is prospective only; no credit is allowed for tax remitted before the change.

Q: What risk does a retailer face during the transition between methods?
A: If an audit determines sales tax wasn't properly reported and paid during the transition (tracking tax-paid vs. tax-due sales), the retailer is liable for the tax plus applicable penalty and interest.

Q: Does switching to cash basis affect installment sales with sales tax included in the balance?
A: It can — Rule 3.302(f) requires separately reporting and remitting a portion of interest collected on the sales-tax portion of installment balances, on a separate return for the same reporting period.

Q: Can any retailer rely on this exact permission to switch accounting methods?
A: Not directly. This is a Texas STAR letter ruling binding on the Comptroller only for the taxpayer it addresses (34 Tex. Admin. Code Rules 3.1, 3.10); confirm your own transition procedure with a tax professional.

From: Gilbert Zamora

To: "**"

Subject: COMPANY A

Dear **:

Thank you for your e-mail inquiry requesting permission for your client, the
COMPANY A, to switch from reporting sales tax on the accrual basis of
accounting to a cash basis for sales tax purposes.

Your client has been experiencing a large increase in "COMPANY A Charge" sales
during the last several months and the cash reporting method would more closely
coincide with sales taxes collected. You asked if there is any paperwork that
needs to be processed before this change can be made. Response: It is
permissible for your client to change from an accrual to a cash basis of
accounting (remitting tax as payments are received) for sales tax purposes. No
special forms need to be completed. However, the change from the accrual basis
to the cash basis for reporting the sales and use tax is prospective only.
Credit will not be allowed for tax remitted prior to the change in reporting
procedures. Since your client may have tax-paid sales (sales prior to
conversion) and tax-due sales (sales made after the conversion) a procedure
must be established to correctly account for sales tax on remittances from
customers during the transition period. If an audit should determine that the
sales tax has not been properly reported and paid, your client would be liable
for the tax, plus applicable penalty and interest.

In changing to a cash basis of accounting, your client may be affected by
Subsection (f) of Rule 3.302 regarding credit sales. Retailers who make
installment sales of taxable items, include the amount of sales tax due in the
outstanding balance, and charge interest on the outstanding balance are
required to send a portion of the interest collected on the sales tax portion
of installment sales to the state in addition to the regular sales tax due the
state. This additional amount is to be reported and remitted on a separate
return, but for the same reporting period as the retailer is currently filing
sales tax returns.

Please advise if your client will have interest to remit to the state so that
the reporting form can be sent. A complete set of rules, along with the text
of the Tax Code, and a wealth of other information are available through our
website at through the "Texas Taxes" window.

This opinion is based on the facts presented. Other facts though similar may
provide a different result. I hope this information answers your questions.

Our client, COMPANY A, would like to know if it is possible to go from
reporting sales on a accrual basis to a cash basis for sales tax purposes. They
have been experiencing a large increase in "COMPANY A Charge" sales during the
last several months and the cash reporting method would more closely coincide
with sales taxes collected. Is there any paperwork that needs to be processed
before this change can be made.

Thank you for your prompt response.
