Annual Bookkeeping

Service details

Stop worrying about the back office and get your time back for growing the business.
Annual bookkeeping from STA Accounting and Consulting, run by a professional team properly licensed under Thai law. Your business gets accurate, transparent financial records filed on time with every authority, without hiring in-house accounting staff and without buying accounting software or extra computer systems. We work closely with you, like a partner inside your organisation, to get the most out of every step.

1. Digital systems and legal readiness (Customer Service)
Appointment of an accountant to act as your company's registered accountant, as the law requires.
Full online filing: financial statements through DBD e-Filing and tax returns over the internet.
Handling the paperwork through the accounting cycle, including the newspaper notice calling the annual shareholders' meeting, plus collection and delivery of your accounting documents.

2. Bookkeeping, document control and year-end closing (Accounting and Closing)

Benefits to be received

1. You pay for the work actually done, not for monthly service you never use
A business with few transactions and no monthly filing duty does not need to pay a monthly fee for all 12 months. The annual package is charged once, based on the volume of transactions for the whole year.

2. Exactly as complete under the law. This is not a cut-down service
A full set of financial statements, the PND 50 filing, submission of the statements to the Department of Business Development, and a registered accountant legally responsible for the work, the same as the monthly service.

3. Send your documents once, not every month
Suited to an owner who has no time to organise paperwork regularly. Send one batch after you accept the engagement, and the team carries it through to the end.

4. You know the whole cost from the start
You see the full amount for the year on the day we quote. Nothing gets added along the way, so cash planning is simple.

5. A dormant business has its own rate
A business with no income and no expenses for the whole accounting year is charged at the dormant rate, not the same as a business with real transactions. This has to be confirmed in writing every year.

6. Move up to the monthly service as the business grows
When the transactions increase or you become liable to file monthly, you can move to the monthly service using the same carried-forward balances. You do not have to start the system again.

7. The limitation you should know before choosing, said plainly
The annual package does not include monthly filing. If the business is VAT registered, or makes payments subject to withholding tax, or has employees for whom Social Security must be remitted, it still has to file every month. In that case you should use the monthly service from the outset. It is cheaper and safer.

If you are not sure which group your business is in, tell us your document volume and the nature of the business and the team will assess it for you first.

Criteria for calculating service fees

Annual closing fees

A business with no activity, a dormant company - THB 5,000 a year
For a business with no income and no expenses at all during the accounting year. Covers the bookkeeping, closing the financial statements, submitting them to the Department of Business Development, and filing PND 50. The condition is that you confirm in writing every year that there really was no activity. If even one transaction occurs during the year, we go back to the normal rate and always tell you before issuing an invoice.

A business with activity - from THB 6,500 a year
This rate is for a business with no more than 30 transactions a year and straightforward bookkeeping. Above that, the fee rises with the actual transaction volume and the difficulty of the work.

If you want the closing and the audit on one invoice
A dormant company that also needs a CPA to certify the statements can take a combined package of bookkeeping, closing and audit at THB 10,000 a year. See the audit service page for details. The bookkeeping fee and the audit fee are always two separate items. This is the point people misunderstand most often.

Already on STA's monthly service? You do not pay for closing twice.
Closing the financial statements, filing PND 50, submitting the statements to the DBD and preparing the Bor Or Jor 5 are already included in the monthly fee. The rates on this page apply only to a business that is not on the monthly service.

All the rates above are per year and exclude 7% VAT.

The fee is based on transactions per year, not per month. Read this carefully, because it is a different unit from the monthly fee table. A business averaging 30 documents a month is about 360 transactions a year.

What we price on
- The number of transactions for the whole accounting year
- The type of business and how complex the bookkeeping is
- The condition of the documents received, and how complete the opening balances from the previous accountant are

Not included in this package
- Monthly tax filing, such as PP 30, PND 1, 3, 53 and Social Security contributions
- The audit fee, which is charged separately and always uses an outside licensed CPA
- The fee excludes 7% VAT

Statutory deadlines to plan around together
- Hold the shareholders' meeting to approve the financial statements within 4 months of the accounting year end
- Submit the financial statements through the DBD e-Filing system within 1 month of that approval
- File PND 50 within 150 days of the accounting year end

The sooner your documents reach us, the more time there is to review and fix problems before the deadline.
