The utility company will cease charging state and RTD/CD sales taxes and state collected local taxes. If your business is less than 75% exempt, see the instructions below.

Box No. Phone number City State Utility Account Number Gas ZIP Electricity (Complete a separate form for each) For the purpose of this exemption, the term “industrial use” has the following meaning: the use of gas or electricity in a continuing business activity of manufacturing or producing tangible personal property or services. The following uses do not qualify for the exemption: electricity and or gas used in offices, lunch rooms, laboratories, maintenance rooms, computer rooms, lounges and waiting areas, and usage solely for the comfort of employees. Also, usage prior to or subsequent to the actual exempt activity performed. You must determine the percentage of exemption for each meter, either by using square footage for exempt and nonexempt usage or by determining the actual energy consumption of exempt usage. Keep a copy of your computations with your records and submit a copy to the Department of Revenue with any claim for refund of taxes paid. If usage is more than 75% exempt submit this Certificate to your utility supplier and it will not add tax to your utility billings. If less than 100% exempt, you must remit tax on the non-exempt portion. If usage is less than 75% exempt, do not submit this form to your utility supplier, but continue to pay tax on your utility bills and, in January of each year, submit a claim for refund of the tax paid on the exempt portion (DR 0137B). Under penalty of perjury, I swear or affirm that the gas and/or electric service which is billed to the above applicant under a commercial rate by the supplier named herein is used for industrial use and therefore qualifies for exemption under 39-26-102(21) C.R.S.

About the Sales Tax

Sales taxes are applied to the transfer of goods (and sometimes services) to the end consumer in most of the fifty states, and are collected by the vendor from their customers and remitted to the state taxation department on a regular basis. Therefore, most sales tax related tax forms are applicable to businesses, and not private individuals.
