Our Tax Preparation Process in Bangkok

At B-accounting, we take you through tax preparation and filing in four clear steps:

1

Meeting

A prerequisite to discuss your financial situation and fiscal needs, so our tax specialists fully understand the taxation implications for your business and which taxes are due to the Thai Revenue Department.

2

Records Collection

We track and organize your financial transactions and company statements to prepare your taxes accurately and on time, with bookkeeping support available if you need it.

3

Tax Filing

Your tax forms are prepared and filed before each official deadline, starting with withholding tax then VAT. E-filing gets you an extra week, and payment can be made by cheque, cash, or bank transfer.

4

Monthly Reporting

A clear, concise fiscal picture of your business every month, with guidance on what your numbers mean for your next business decisions.

Tax Preparation FAQ

What taxes does B-accounting prepare and file?

We handle corporate income tax, personal income tax, VAT, withholding tax, and international tax matters, along with tax due diligence reviews.

When are Thailand's tax filing deadlines?

Deadlines vary by tax type — withholding tax and VAT are generally filed monthly, while corporate income tax is filed twice a year (half-year and annual). We track every deadline for you and file on time.

What happens if I file late?

Late filing can trigger surcharges and penalties from the Thai Revenue Department. We build in buffer time ahead of each deadline specifically to avoid this.

I already have a bookkeeper — do I still need a tax consultant?

Bookkeeping and tax preparation are related but distinct. A tax consultant makes sure your books translate into correctly filed, compliant tax returns, and advises on the tax implications of business decisions.

Can you help with international tax matters?

Yes — we advise on cross-border tax questions, including how Thailand's double tax treaties may apply to your business.

What documents do I need to provide?

This depends on your tax type and business structure. After our initial meeting, we'll give you a clear checklist of the records and statements we need.
