Electricity Tax for Business

Is an Electricity Bill Subject to Withholding Tax? At What Rate — and the VAT Invoice

When a business pays the utility for electricity, does it withhold tax, at what percent, and can the electricity be used as input VAT — how do you get the tax invoice? This page lays it out clearly for business owners, accountants and commercial tenants: the tax treatment of “electricity”, both the withholding-tax side and the VAT side, plus the case where you pay electricity through a building owner/landlord — referenced to Revenue Department rules.

Electricity bought directly from the utility (MEA / PEA) is NOT subject to withholding tax — the rate is 0%. For two legal reasons: (1) electricity is “goods” under Section 77/1(9) of the Revenue Code, and a sale of goods is outside the scope of withholding tax (which applies to services / hire-of-work / rent); and (2) the utility is a state enterprise, not a company or registered partnership under Section 39, so the payer has no withholding duty (per Revenue Department ruling กค 0706/11293). But electricity carries 7% VAT — a VAT-registered business can request a full tax invoice in the company's name to claim it as input VAT. Watch out: if you pay “electricity” through a landlord/building owner as a service charge or bundled into rent, that portion may fall under 3–5% withholding (see the table below).

Does an Electricity Bill Need Withholding Tax?

No — the rate is 0% for electricity a business pays directly to the Metropolitan Electricity Authority (MEA) or the Provincial Electricity Authority (PEA), whether the payer is an individual, a shop, or a company/partnership. The reasons are in the next section. VAT is a separate matter — electricity always carries 7% VAT.

Why Electricity Is Exempt (Goods + State Enterprise)

Two mutually reinforcing reasons keep electricity outside withholding:

Reason 1 — electricity is “goods”, not a service: under Section 77/1(9) of the Revenue Code, “goods” includes electric current. Selling electricity is therefore a sale of goods, and buying goods is outside the scope of withholding tax (unlike services, hire-of-work or rent, which are withheld).

Reason 2 — the utility is a state enterprise: MEA and PEA are state enterprises, not a company or registered partnership under Section 39, so a payer to the utility has no withholding duty. The Revenue Department addressed this directly in ruling No. กค 0706/11293 (payments to the PEA).

Water charges (from MWA/PWA) follow the same principle — a state enterprise and/or a sale of goods — and are likewise not withheld.

Paying Electricity Through a Landlord — Withhold? At What %

If a tenant does not pay the utility directly but pays the landlord/building owner, whether to withhold depends on what the charge is billed AS:

Paying Electricity Through a Landlord — Withhold? At What %
How the electricity is paidWithholding
Bought directly from the utility (MEA/PEA)None (goods + state enterprise)
Landlord recharges “actual electricity” (pass-through of units)Generally none (still electric current = goods)
Billed as a “service charge”3% (payer is a juristic person)
Bundled into / billed as “property rent”5% (the rent portion)
The 3% (service / hire-of-work) and 5% (property rent) figures are the standard rates in Revenue Department order ท.ป.4/2528 for juristic-person payers. What decides it is what the invoice calls the charge and whether possession of property is handed over (rent = handover, service = none). For borderline cases, confirm with the Revenue Department hotline 1161.

The VAT Invoice: Getting It in the Company Name & Claiming Input VAT

Even without withholding, electricity carries 7% VAT on the bill (see where the VAT line sits in how to read the electricity bill). A VAT-registered business can use that VAT as input VAT to credit/refund. The key condition is holding a full-format tax invoice stating correctly:

The company's name, address and 13-digit tax ID, matching its registration (not a personal name or the landlord's).

The words “Tax Invoice”, invoice number and date, the electricity line, the pre-VAT amount and the 7% VAT shown separately.

The meter/bill in the company's name — if the meter is still under a personal name or a previous owner, transfer the account to the company or ask the utility to issue the invoice in the company's name.

Both utilities offer tax-invoice / e-Tax-Invoice issuance and e-Service portals for business customers: MEA via MEA e-Service and MEA services; PEA via PEA e-Service. Ask about issuing the invoice in the company's name at MEA 1130 / PEA 1129.

Booking Electricity in the Accounts + Scope of This Page

In the accounts, electricity is an operating expense of the business, while the 7% VAT is recorded separately as input VAT (if VAT-registered and holding a full tax invoice). Keep the original tax invoice as support for the PP.30 filing and any audit. Electricity used for the business is a deductible expense for corporate income tax (for the business-side rate structure, see factory & business electricity cost).
This page is only about the tax on “electricity” on the bill, not the tax on a solar system. If you have installed solar and want the depreciation / accounting deduction of the solar asset for a company, see solar tax, depreciation & accounting for business.

FAQ

0% — none. Electricity is “goods” under s.77/1(9) and the utility is a state enterprise (s.39, ruling กค 0706/11293). This holds for both individual and juristic-person payers.

High Business Electricity Bills? Cut Them at the Source With Solar

Handling the tax on electricity correctly helps, but cutting the units you buy from the utility with rooftop solar (self-consumption) saves far more per unit. CapSolar assesses free from your actual bill whether EPC or PPA fits your business.
