Frequently Asked Questions

Does my Thai company need an accountant?
Yes. Thai law requires all registered companies to maintain proper accounting records and have financial statements audited annually by a certified public accountant (CPA). You cannot do this yourself — you need a qualified Thai CPA.
How much does accounting cost for a Thai company?
Monthly accounting fees depend on the number of transactions, employees, and complexity of your business. MJ & Co offers competitive packages for small to medium businesses in Chiang Mai. Contact us for a quote based on your specific needs.
What is the corporate tax rate in Thailand?
The standard corporate income tax rate in Thailand is 20% of net profit. Small companies (paid-up capital under 5 million THB and revenue under 30 million THB) receive reduced rates: 0% on the first 300,000 THB and 15% on profit from 300,001 to 3 million THB.
Do I need to pay personal income tax in Thailand?
If you work in Thailand (with a work permit) or stay more than 180 days in a calendar year, you may be subject to Thai personal income tax. Tax rates are progressive from 0-35%. MJ & Co can handle your personal tax filing alongside your company accounts.
