Permits, registration and tax for a Thai laundromat

Is a health-hazard business licence required?

Yes. Under the Ministry of Public Health notification on health-hazard businesses (B.E. 2558 and amendments), machine washing, drying, ironing and pressing — explicitly including coin-operated washing machines — is a listed activity requiring a licence from the local authority before operating.

The point most often misunderstood: how this is applied depends on each local authority's own by-laws, under the powers the public health legislation grants them. Municipalities and sub-district administrations may differ on which activities need a licence, what documents are required, and the fee. The answer for your specific location can only come from the municipality or sub-district office where the shop will sit.

Before paying a rental deposit, contact that authority's public health division directly and ask whether machine laundry is covered by their by-law, what documents are needed, and how many days the review takes — that timeline affects your opening date.

Commercial registration or a company?

Commercial registration must be filed within 30 days of starting the business. The fee for a new registration is THB 50, filed at the district office, municipality or sub-district administration covering the shop's location.

Whether to operate as an individual or register a company depends on expected revenue, how many branches are planned, and tax planning. Investors planning several branches or using substantial credit often benefit from a company. Discuss it with an accountant rather than deciding from a general article.

When is VAT required, and what other taxes apply?

• VAT: register once business revenue exceeds THB 1.8 million per year, filing within 30 days of crossing the threshold.
• Income tax: personal income tax if operating as an individual, corporate income tax plus accounting and financial statement obligations if registered as a company.
• Signage tax: a shopfront sign is subject to annual signage tax, at a rate depending on its size and character, filed with the local authority.
• Property-related tax depends on whether you own or lease the premises, and on the lease terms.

Shops taking payment through an app record all revenue automatically, which helps with bookkeeping accuracy and filing — and is the data lenders typically want to see when assessing credit for a second branch.

The order to do things in

• Before paying a deposit: ask the local public health division about the licence, and the electricity authority about meter size and three-phase supply.
• Check building and zoning requirements for the premises, and what the lease permits regarding alterations and utility installation.
• File commercial registration, or incorporate, within 30 days of starting the business.
• Apply for the health-hazard business licence with the documents the local authority specifies.
• File signage tax after the sign is installed, and set up bookkeeping for annual filing.
• Track annual revenue and register for VAT immediately once it exceeds THB 1.8 million.

Is there a standard to reference?

The Thai Industrial Standards Institute has published a service standard for laundromats, which investors can use to compare the service standards of the brands they are considering against something other than each brand's own marketing.
