Is electricity subject to sales tax?

It depends on the state and the customer class. Most states tax electricity sales to residential and commercial customers but exempt electricity used in qualifying industrial or manufacturing processes. Some states exempt residential electricity entirely. Others apply reduced rates to certain customer classes. The rate and exemption that applies to each of your customers depends on the state where they are located and how they use the electricity — not a single national rule.

What is a gross receipts tax and how does it differ from sales tax?

A gross receipts tax is levied on a company total revenue from energy sales, not on individual transactions. Unlike sales tax, which is collected from the customer at the point of sale and remitted to the state, a gross receipts tax is an obligation of the seller calculated on total receipts and remitted separately. Several states impose gross receipts taxes on energy companies in addition to or instead of sales tax. The rates, filing schedules, and registration requirements are completely separate from the sales tax system and are frequently overlooked by companies entering new markets.

Do retail energy suppliers need to register in every state where they have customers?

Yes. Operating as a retail energy supplier in a deregulated state requires registration with both the state energy regulatory authority and the state tax authority before you can legally supply and bill customers there. Economic nexus rules also apply — once you cross the sales threshold of a state, you have a collection obligation regardless of whether you have physical presence. Multi-state retail energy suppliers typically have registration and filing obligations in every state where they actively market and sell to end users.

What exemptions apply to industrial and manufacturing energy customers?

Most states exempt electricity and natural gas used directly in a qualifying manufacturing or industrial process from sales tax. The definition of qualifying use varies by state — some states require that the energy be used predominantly in the production process, others apply a direct-use test, and others have specific eligible NAICS codes. Collecting the correct exemption certificate from each industrial customer and validating that it meets the destination state requirements is essential. An invalid or missing certificate shifts the tax liability to the supplier on audit.

How does deregulation affect sales tax compliance for energy suppliers?

In deregulated markets, the retail energy supplier — not the utility — is responsible for collecting and remitting sales tax on the supply portion of the customer bill. The utility typically handles transmission and distribution, which may be taxed separately under a different regime. Entering a new deregulated market requires understanding which portion of the bill is taxable, at what rate, under which classification, and which registration the supplier needs before billing begins. Each deregulated state has its own structure and the compliance answer is different in Texas than it is in Illinois or New York.

What triggers an audit for an energy company?

Common audit triggers for energy companies include inconsistent exemption certificate documentation, large volumes of exempt sales without supporting certificates, nexus in a state without registration, gross receipts tax filings that do not reconcile with sales tax filings, and rate changes that were not applied to billing in the correct period. States with active energy audit programs — including New York, Illinois, Texas, and California — use cross-agency data matching to identify suppliers with collection gaps. Proactive compliance and a clean exemption certificate program are the most effective audit prevention tools.

Who we serve

Energy Companies and Utilities at Every Stage of the Value Chain

Retail Energy Suppliers

Retail energy suppliers operating in deregulated electricity and natural gas markets face sales tax collection obligations in every state where they sell to end users, combined with gross receipts tax regimes that vary dramatically by state. The deregulated energy market creates nexus in multiple states simultaneously, often faster than compliance infrastructure can keep pace. Getting the registration, rate, and exemption structure right from market entry is significantly easier than correcting it under audit.

Key obligations

Multi-state sales tax registration and filing
Gross receipts tax compliance
Residential vs. commercial rate differentiation
Exemption certificate management
State utility tax registration
Audit defense

Regulated Utilities

Regulated electric, gas, and water utilities operating under state commission oversight face a distinct compliance profile that combines state-specific utility tax regimes, gross receipts taxes, and sales tax obligations that vary by customer class and end-use. Rate case filings and tariff structures add complexity to the taxability determination for each customer segment.

Key obligations

State utility tax compliance
Gross receipts tax filing
Customer class taxability analysis
Exemption certificate management
Multi-jurisdiction rate and remittance management
Regulatory filing support

Independent Power Producers

Independent power producers selling into wholesale markets and directly to commercial and industrial customers navigate a compliance environment that differs significantly from retail energy suppliers. Wholesale sales, power purchase agreements, and direct retail arrangements each carry different tax treatment depending on the state and the structure of the transaction.

Key obligations

Wholesale vs. retail taxability determination
State sales tax on direct retail sales
Gross receipts tax where applicable
Multi-state nexus analysis
Exemption certificate management for industrial customers
Audit defense

Natural Gas Distributors and Marketers

Natural gas marketers and distributors operating across state lines face some of the most variable indirect tax environments in the energy sector. State taxation of natural gas differs based on end-use classification — residential heating, commercial use, industrial process use, and agricultural use each carry different rates and exemption eligibility in most states.

Key obligations

End-use exemption analysis
Residential vs. industrial rate differentiation
Multi-state sales tax registration
Gross receipts tax compliance
Exemption certificate management
Agricultural and industrial use exemption certificates

Renewable Energy Companies

Renewable energy developers and operators — solar, wind, and storage — frequently encounter sales tax exemptions for equipment and materials used in generation, but the scope and eligibility of those renewable energy tax exemption rules varies significantly by state. Getting the exemption certificate structure right on capital projects can represent material savings. Ongoing operational compliance requires the same multi-state registration and filing management as any other energy company.

Key obligations

Equipment and materials exemption analysis
Capital project tax savings review
State sales tax registration for operational footprint
Gross receipts tax where applicable
Multi-state nexus management
Exemption certificate management

The complexity

Why Energy Indirect Tax Is Different From Every Other Sector

Most sales tax compliance frameworks were built around standard product and service transactions. Energy does not fit that framework cleanly. The same product — electricity or natural gas — can be taxable at one rate for a residential customer, exempt entirely for an industrial customer using it as a manufacturing input, and taxable at a different rate for a commercial customer in the same state. Gross receipts taxes add another layer that operates completely outside the sales tax system and applies at the entity level rather than the transaction level. Deregulated energy market compliance creates simultaneous nexus in multiple states the moment you begin acquiring customers there, and deregulated market tax registration must be handled before billing begins. And state regulatory classification — whether a company is treated as a public utility, a retail energy provider, or a competitive supplier — determines which tax regime applies in the first place. Getting all of these right, simultaneously, across multiple states, requires a compliance team that understands retail energy supplier sales tax, electricity sales tax, natural gas sales tax, and the broader energy sector specifically — not just indirect tax generally.
