Collecting Texas sales tax: how to track it in the books so filing is never a guess

Treat it as money you are holding, not money you earned

Sales tax you collect from customers belongs to the State of Texas from the moment you collect it, so your books should record it as a liability, not as income. Set up a sales tax payable account, make sure each taxable sale records the tax separately, reconcile that account to every return you file, and pay from it on time. Done this way, the amount on your return matches your books, and the money is never accidentally spent on payroll.

I see sales tax problems in otherwise well-run businesses all the time, and they almost always start in the books rather than on the return. Tax gets lumped in with sales, so revenue looks higher than it is and the return has to be estimated. Or the tax is recorded correctly but nobody checks that the liability goes back to zero after each payment.

This guide covers the Texas basics every owner should know, how to set up the books, and the monthly checks that keep returns accurate. It is general information; confirm the rules for your products and services with the Comptroller or a tax professional.

The Texas rules worth knowing first

According to the Texas Comptroller, Texas imposes a 6.25 percent state sales and use tax on retail sales, leases and rentals of most goods, as well as on taxable services. Local jurisdictions can add up to 2 percent more, for a maximum combined rate of 8.25 percent. Because local rates vary, the rate you charge depends on where the sale happens, and the Comptroller provides an online rate locator to look up the correct rate for an address.

The Comptroller's permit page says you need a sales and use tax permit if you are engaged in business in Texas and you sell or lease tangible personal property or sell taxable services in the state. That second part catches some service businesses off guard, because not every service is taxable but some are. If you are unsure whether what you sell is taxable, check the Comptroller's guidance on taxable services before you start collecting, or before you decide not to.

• State rate: 6.25 percent, per the Comptroller
• Local add-ons: up to 2 percent, for a combined maximum of 8.25 percent
• Permit needed if you sell taxable goods or taxable services in Texas
• Rate depends on location, so use the Comptroller's rate locator

Filing dates and what late costs

After your permit is approved, the Comptroller notifies you whether you will file monthly or quarterly, and some businesses file yearly. Its sales tax page lists monthly returns as due on the 20th of the month after the reporting month, and quarterly returns as due April 20, July 20, October 20 and January 20. If a due date falls on a weekend or legal holiday, the next working day is the due date.

Filing late is expensive relative to the work of filing on time. The Comptroller lists a $50 penalty for each report filed after the due date, a 5 percent penalty if the tax is paid one to 30 days late, and a 10 percent penalty if it is paid more than 30 days late, with interest starting 61 days after the due date. On the other side, it allows permitted sellers a discount of 0.5 percent of the tax timely reported and paid. In other words, filing on time is paid for; filing late is charged for.

Setting up the books so sales tax tracks itself

The goal is that every taxable sale automatically splits into two parts: the sale, which is your revenue, and the tax, which goes to a liability account. In QuickBooks that means turning on sales tax, entering the correct rates for the locations where you sell, and marking each product or service as taxable or nontaxable. If you sell through a point-of-sale system or an online store, the integration with your books has to bring the tax across as tax, not as part of the sale.

Exempt sales need records too. When a customer buys for resale or claims an exemption, keep the certificate they give you on file, organized so you can find it later. A sale recorded as exempt without a certificate behind it is a sale you may have to defend.

• Turn on sales tax in your accounting software and set the correct rates
• Mark each product and service as taxable or nontaxable
• Make sure point-of-sale and online store integrations record tax separately
• Record tax collected in a sales tax payable account, never in income
• Keep resale and exemption certificates on file for exempt sales

Selling across a metro area with different local rates

A business in the Dallas area can easily sell into a dozen cities in a week: a shop in one suburb, deliveries to another, installations across the county line. Because local rates differ, the rate on each invoice may not match the rate at your own address. Which local rate applies depends on how and where the sale is made, and the Comptroller publishes detailed guidance on it; if you deliver or ship, read it or ask a tax professional before you set up your rates.

In the books, the practical rule is to let the software apply the rate tied to each sale's location rather than typing a single rate on every invoice. Then, when it is time to file, the detail by location is already in the books instead of being rebuilt from memory.

The monthly check that catches mistakes early

Each month, before you file or as part of the close, compare three numbers: the taxable sales in your books, the tax collected in your books, and the amount on the return. They should agree. Then, after you pay, check that the sales tax payable account drops by the amount paid. If the account keeps growing, something is wrong: a payment recorded as an expense, tax collected but never remitted, or a sale entered twice.

This reconciliation belongs inside the regular monthly close, alongside the bank and credit card reconciliations; I walk through the full sequence in what happens during a monthly bookkeeping close. If the account has drifted for months and you are not sure where the difference came from, the warning signs in books that look reconciled but are wrong usually point to the cause.

Common sales tax mistakes in small business books

The most common mistake is recording gross receipts, tax included, as sales. Revenue is overstated, the return has to be backed out by hand, and income tax is calculated on money that was never yours. The second is paying the return from the operating account and recording the payment as an expense, which double-counts the tax and leaves the liability on the balance sheet forever.

Others are about rates and timing. Charging one rate everywhere when you deliver to locations with different local rates. Forgetting to account for the timely filing discount, so the books and the bank never agree. Treating the money in the account as available cash, then coming up short on the 20th.

• Recording tax-included totals as revenue
• Booking the sales tax payment as an expense
• Using a single rate when sales happen in different local jurisdictions
• Not recording the timely filing discount
• Spending collected tax before the return is due

Cash timing and your income tax method

Sales tax often sits in your bank account for weeks before it is due, which makes the account look healthier than it is. Some owners keep a separate savings account and move the collected tax into it each week, so it is never mistaken for operating cash. It is a simple habit that prevents a hard month from becoming a sales tax problem.

Sales tax timing is also separate from the method you use for income tax. Whether your books run on cash or accrual for income tax purposes, the sales tax return follows its own reporting rules, so confirm with your tax preparer how sales are reported for your business. If you are weighing the two income tax methods, I explain the differences in cash versus accrual accounting.

If you are already behind on returns

If you have collected sales tax and not filed, or not collected when you should have, do not wait. Penalties and interest grow with time, and the books are the starting point for fixing it. The first job is to rebuild accurate taxable sales by period, which usually means reconciling the bank and sales records for the months involved. That process looks a lot like the one in my guide to catching up books that are months behind.

Once the numbers are rebuilt, the missing returns can be prepared from real figures instead of estimates. If you are unsure whether you owed tax in the first place, get advice from a tax professional before filing anything, because the answer depends on exactly what you sell.

Sales tax as part of monthly bookkeeping

In our bookkeeping service, sales tax filing is included where it applies, alongside reconciliations, accounts payable and receivable and monthly reports. That means the tax is recorded correctly at the point of sale, reconciled in the close and filed from the same books. Clients in Plano, Garland, Flower Mound and across the Dallas–Fort Worth area get one team for both the books and the return.

We start with a free 30-minute consultation where we look at what you sell, where you sell it and how your systems record it, and then send a written flat-fee proposal. If something needs fixing first, we tell you up front.
