Is bottled, purified mineral water taxable in Texas, whether sold directly or through vending machines?

Plain-English summary

A company planning to buy water from local municipalities, purify it through reverse osmosis (removing impurities), add minerals back in, and sell it bottled -- both through direct sales and vending machines -- asked whether either sales channel would trigger Texas sales tax.

The answer is a clean no, on both channels: water, spring water, sparkling water, and mineral water are not taxable, regardless of whether it's sold at retail or through a vending machine. The purification-and-remineralization process described (reverse osmosis treatment, then adding minerals back) doesn't change that outcome -- it's still just water for tax purposes.

The one condition that would flip this: if the water is flavored or has any other ingredients added, it becomes taxable. So the exemption is specific to water in its essentially unflavored, unadulterated form (even mineral-enhanced), not to bottled beverages generally.

What this means for you

Bottled water companies and distributors

Plain, spring, sparkling, or mineral water stays exempt from Texas sales tax through any sales channel, including vending machines -- purification processes like reverse osmosis and adding minerals back don't affect this. The moment you add flavoring or other ingredients, the product becomes taxable.

Vending machine operators

Don't assume vending-machine sales automatically trigger tax that a direct retail sale wouldn't (or vice versa) -- for bottled water specifically, the channel doesn't matter; only the water's own flavored/unflavored status does.

Accountants and tax professionals

A clean, simple bright-line rule (flavored/adulterated = taxable, plain/mineral = exempt) worth having on hand for any beverage-industry client, and a reminder that this exemption analysis is not itself grounded in a specific numbered Tax Code section in this letter -- it reflects the Comptroller's general food/beverage exemption policy for water products.

Common questions

Q: What makes bottled water taxable?
A: Adding flavoring or any other ingredients to the water.

Q: Can I rely on this letter for my own bottled water business?
A: No. It is based on the specific facts presented and can only be relied on by the taxpayer to whom it was issued.

Original ruling text

April 22, 1999

Dear **:

Thank you for your recent letter regarding the taxability of purified water.

In your letter you stated that your client will purchase water from local
municipalities and will purify the water through a reverse osmosis treatment
system to remove impurities. Once purified, minerals will be added back to the
water. The water will then be bottled and sold through direct sales and
through vending machines.

Your questions are as follows:

1. Are retail sales (non-vending machine) of this product subject to sales tax?

2. Are vending machine sales of this product subject to sales tax?

Sales of the purified mineral water, whether through vending machines or not,
are not taxable. Water, spring water, sparkling water, or mineral water are
not taxable. However, if the water is flavored or has any other ingredients,
it would be taxable.

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

You may call me toll free 1-800-531-5441, extension 5-9787, if you have any
questions or need more information. The direct line is 512/305-9787. You may
also write to Tax Policy Division, Comptroller of Public Accounts.

Sincerely,

Philip Knisely
Tax Policy Division
