When can a Texas retailer accept an export certificate in good faith, and when does a sale to a Mexican buyer become taxable?

Subject

Certificate Of Exportation — Good Faith — Retailer Cannot Accept If He Knows Items Have Not Yet Been Exported

Plain-English summary

This 1992 Texas Comptroller letter answers a furniture retailer's question about selling to buyers who plan to take the goods to Mexico. The Comptroller makes two related points.

First, an export certificate — the document a retailer relies on to treat a sale as a tax-exempt export — cannot be accepted in good faith if the retailer already knows the goods haven't actually left the country yet. In other words, the certificate has to reflect reality at the time it's accepted; a retailer can't rely on it as cover when it knows the export hasn't happened.

Second, and more practically helpful to the retailer, sales tax isn't owed until the sale itself is legally complete. A sale happens when title or possession of the goods transfers for payment. Since furniture normally isn't "titled" like a car, that means the sale isn't complete until the buyer (or the buyer's representative) actually takes possession of the furniture — even if the retailer was paid earlier.

The letter then offers a practical structuring tip: if the retailer ships the furniture directly to a customs broker, the buyer doesn't take possession until the goods cross into Mexico. The broker certifies the export and provides documentation, so the retailer never has to collect Texas sales tax and then refund it once the export is confirmed.

What this means for you

Retailers selling to buyers who plan to export goods

If your customer plans to take purchased goods across the border, don't accept an export certificate if you already know the goods are still sitting in your store or warehouse. Wait until the export has actually happened, or structure the transaction so that possession doesn't transfer until the goods are on their way out of the country.

Furniture and other non-titled goods sellers

Because tax generally attaches when a sale is complete (transfer of title or possession), and non-titled goods like furniture don't have a paperwork transfer point, the practical trigger is when the buyer or their representative physically takes possession. Payment alone does not complete the sale for tax purposes.

Businesses with recurring export sales

Consider routing export sales through a customs broker. If the broker takes delivery and the buyer doesn't get possession until crossing into Mexico, the broker's own export certification can support treating the sale as exempt from the start, avoiding the collect-then-refund cycle described in the letter.

Common questions

Q: Can I ever accept an export certificate for goods that haven't shipped yet?
A: This letter says no — not if you already know the goods have not yet been exported. Accepting the certificate anyway would not be in good faith.

Q: When exactly do I have to charge sales tax on a sale to someone exporting the goods?
A: Not until the sale is complete. A sale requires transfer of title or possession for payment. For goods like furniture that aren't titled, that means the sale completes when the buyer (or their representative) takes physical possession — not simply when you receive payment.

Q: How can I avoid collecting tax and then having to refund it once an export is verified?
A: The letter suggests shipping directly to a customs broker under contract, so the buyer doesn't take possession until the goods cross into Mexico. The broker then certifies the export and supplies documentation, letting the sale be treated as exempt without a collect-and-refund cycle.

Q: Does this ruling apply to me even though I'm not the original requester?
A: Not directly. Under the Comptroller's STAR system rules, a detrimental reliance claim based on this letter is available only to the taxpayer it was issued to. Others can use it as a guide to the Comptroller's reasoning but should confirm current policy for their own facts.

Original ruling text

August 3, 1992

Dear **:

Thank you for your recent letter regarding the tax treatment of items exported
to Mexico. ** cannot accept an export certification in good faith for
items that they know have not yet been exported.

However, you are not required to collect sales tax until the sale is made. A
sale is defined as the transfer of title to or possession of tangible personal
property for a consideration. Since furniture is not normally titled, a sale
would not be complete until the buyer or the buyer's representative got
possession of the furniture, even if you received payment at an earlier date.

As we discussed, ** may find it easier to handle its tax obligations
on sales to Mexican nationals by contracting directly with customs brokers to
handle exports on their behalf. If the furniture were shipped directly to your
broker, the buyer would not take possession of the furniture until it crossed
into Mexico. Your customs broker would certify the export and provide your firm
with the documentation. In this way, **** would not have to collect and
then refund the tax.

I hope this information is helpful.

If you have questions or need more information, please call or write. You may
reach me by calling toll free, (800) 531-5441. My direct line number is (512)
