For a car wash, fuel, and quick-oil-change business in Texas, which charges are taxable and which are not?

Plain-English summary

A newly opened business — a coin-operated car wash with regular and unleaded fuel and a quick-oil-change service — asked the Comptroller, in writing, exactly what it must charge sales tax on. (The owner said they'd gotten varying answers.) The Comptroller sorted the business's charges into taxable and nontaxable:

Do NOT collect sales tax on:

1. Car wash receipts.
2. Gasoline sales.
3. Lump-sum charges for quick oil changes, and lump-sum charges to replace wiper blades, belts, and hoses. For these, you pay tax to your supplier when you buy the items — you are the consumer.

DO collect sales tax on:

1. Vending-machine sales of disposable towels.
2. Charges for oil, filters, belts, hoses, etc., when the labor and materials are separately stated to the customer. In that case you are a retailer of those items, not the consumer — so you don't pay tax to your vendor; instead you issue a properly completed resale certificate and collect tax from the customer.

The pivot is lump-sum vs. separated billing: bill the oil change as one lump sum and you're the consumer who pays tax up front; separately state the parts and labor and you're a retailer who buys tax-free for resale and collects tax from the customer.

What this means for you

Car wash / quick-lube / fuel operators

Car washes, gasoline, and lump-sum oil-change and wiper/belt/hose jobs are not charges you tax the customer on — but you owe tax to your suppliers on the parts and materials, because you consume them. Build that supplier tax into your pricing.

If you separately state parts

The moment you separately state the parts (oil, filters, belts, hoses) and the labor to the customer, the tax treatment flips: you become a retailer, buy the inventory tax-free with a resale certificate, and collect sales tax from the customer on those parts. Pick your billing method deliberately and apply it consistently.

Don't forget the vending machine

Disposable towels sold from a vending machine are taxable retail sales — collect tax on those regardless of the car-wash treatment.

Common questions

Q: Do I charge sales tax on car washes and gasoline in Texas?
A: No. The Comptroller told this operator not to collect sales tax on car wash receipts or gasoline sales.

Q: Is a lump-sum quick oil change taxable to the customer?
A: No — but you pay tax to your supplier on the oil, filter, and other items, because you are the consumer when you bill lump-sum.

Q: How do I make the parts a taxable retail sale instead?
A: Separately state the labor and materials to the customer. Then you are a retailer: buy the parts tax-free with a resale certificate and collect sales tax from the customer.

Q: Are the vending-machine towels taxable?
A: Yes. Vending-machine sales of disposable towels are taxable.

Q: Can I rely on this 1988 letter today?
A: Treat it as guidance only. It is based on the facts presented and can change with different facts; on the STAR system it binds the Comptroller only as to the taxpayer it was issued to and may no longer reflect current policy.

Citations and references

Rules and statutes: The letter applies the consumer-versus-retailer distinction for lump-sum versus separately stated repair charges (and the resale-certificate mechanism) but does not cite a specific Tax Code section or Comptroller rule by number.

Original ruling text

July 20, 1988

Dear ***:

Thank you for your letter dated June 28, 1988.

You should not collect sales tax on the following items in your business:

1. Car wash receipts
2. Gasoline sales
3. Lump-sum charges for quick oil changes and lump-sum charges for
   replacement of wiper blades, belts, and hoses. You should pay tax to your
   supplier on these items at the time of purchase.

You should collect sales tax on the following items in your business:

1. Vending machine sales of disposable towels.
2. Charges for oil, filters, belts, hoses, etc. if the labor and
   materials charges are separately stated to the customer. In this situation you
   should not pay tax to your vendor at the time of purchase on these inventory
   items; you should issue a properly completed resale certificate instead. You
   are considered a retailer of these items, not the consumer.

This opinion is based on the facts presented. If there are additional or
different facts, the opinion may change.

If you have any questions or need more information, please call our
toll-free number 1-800-531-5441. The regular number is 512/463-4600. You may
write me at Tax Correspondence, Comptroller of Public Accounts.

Sincerely,

Julie Pesl

Gentlemen:

I have recently opened a business in **, Texas and have
inquired about sales tax liability. I get varying answers; therefore, I am
requesting that you send me, in writing, a ruling on whether I am to collect
sales tax.

The nature of the business is as follows: Coin-operated car wash, regular and
unleaded fuel, and a quick-oil change. With the quick oil change, I offer the
oil filter, 5 quarts of oil, and the checking and/or servicing of various
things having to do with the car - wiper blades, tires, belts, hoses. Nothing
is sold except that which is part of the package - oil and/or air filter. Am I
to collect sales tax on the price I charge?

In connection with the car wash, I have a vending machine where I sell
disposable towels.

I have been open approximately 3 weeks and would like to have word from you at
your earliest convenience.

Sincerely,
