A dormant company in Thailand is a registered entity that has stopped trading but remains on the Department of Business Development (DBD) register. Foreign business owners sometimes assume that a company with no revenue has no accounting or tax obligations, an assumption that leads to years of missed filings before the company is sold, dissolved or flagged by the DBD.
This guide explains what filing and compliance obligations a dormant company continues to carry with the Revenue Department and the DBD each year, helping business owners budget for the right filings and avoid the penalties that build up when they are skipped.
- A dormant company in Thailand continues filing PND 50 and PND 51 as nil corporate income tax returns and, where VAT registered, the monthly PP.30 return, even with no revenue for the year.
- A dormant company remains subject to the annual audit requirement, and failure to comply may result in penalties regardless of whether the company carried on business during the year.
- VAT deregistration can reduce the filing burden, but any outstanding input VAT credits must be resolved before deregistration.
- Late or missed filings carry separate penalties from the Revenue Department and the DBD, and directors can be held personally liable for AGM and financial statement failures.
- Once compliance costs outweigh the value of staying dormant, dissolution is often the more practical option.
What is a dormant company?
A dormant company, also known as a shelf company, is an entity that has been legally registered but does not engage in any business activities.
What are the benefits of a dormant company?
A dormant company enables business owners to keep a company available for future use, allowing operations to commence when needed without incorporating a new entity.
Future use
Keeping a company dormant avoids the cost and hassle of registering a new entity if the business restarts. A company can also be incorporated in advance and held dormant indefinitely, provided its accounting obligations stay current.
Intellectual property protection
A dormant company keeps its name reserved, since dissolving a company releases the name for others to use. Logos, slogans and designs can also be protected by registering them with the Department of Intellectual Property.
Reduced running costs
Ongoing costs are limited to the company’s annual accounting fees and any virtual office rental.
Tax returns required for a dormant company
A dormant company keeps a reduced but real set of filing obligations with the Revenue Department, and which forms apply depends on whether it stays VAT registered and whether it makes any payments during the year.
The annual and half-year corporate income tax returns stay due regardless of activity, filed as nil rather than skipped. The monthly value-added tax return follows the same logic for a VAT-registered company and is often the filing owners overlook first since there is nothing to report for most months. Any payment the company makes during the year, such as its own audit fee, usually carries a small withholding tax obligation too.
The following table summarises these filings and their deadlines.
| Form | Purpose | Deadline |
|---|---|---|
| PND 50 | Annual corporate income tax return (nil) | Within 150 days of the financial year end |
| PND 51 | Half-year corporate income tax return (nil) | Within two months of the first six months of the accounting period |
| PP.30 | Monthly VAT return, if VAT registered | 15th of the following month (23rd for e-filing) |
| PND 1 / 3 / 53 | Withholding tax on any payments made | 7th of the following month (15th for e-filiing) |
Missing any of these deadlines triggers certain penalties. Filing as a nil return rather than skipping it altogether also keeps the company’s compliance record intact with the Revenue Department, which matters if it later applies for a work permit, opens a bank account or resumes trading.
Auditor requirement for a dormant company
Thai law requires every registered company, dormant or trading, to have its financial statements audited each year by a licensed Certified Public Accountant (CPA) before the accounts go to shareholders at the Annual General Meeting (AGM) and get filed with the DBD and the Revenue Department. This applies even where the company recorded no transactions during the year, since the audit confirms the nil position rather than a level of profit.
A CPA still checks nil balances, related-party loans, accumulated losses and any residual assets such as a bank balance or office deposit, even on a dormant file. This is a genuine annual cost rather than a nominal formality, though it is typically lower than the fee for a trading company given the reduced transaction volume to test. A list of licensed auditors is available through the Federation of Accounting Professions (TFAC), the statutory body regulating the profession in Thailand.
Skipping the audit adds cost rather than removing it. Non-compliance carries separate exposure on two fronts: not preparing or submitting audited financial statements to the DBD and not holding the AGM within four months of the financial year end.
VAT deregistration for a dormant company
A company does not need to keep its VAT registration once it stops trading, and dropping it removes one recurring monthly filing. Under Section 85/10(1) of the Revenue Code, a VAT registrant whose taxable turnover has stayed below the small business threshold for at least three consecutive years can apply to the Revenue Department to cancel the registration, a test most dormant companies meet once enough time has passed.
Deregistration tends to make sense where there is no near-term plan to resume VAT-taxable sales and no ongoing need to reclaim input VAT. Where a return to trading is likely within a year or two, keeping the registration open is often the more practical choice.
The process starts with an application to cancel the registration (Form P.P.09) at the relevant Area Revenue Office, supported by a final VAT return covering the period up to deregistration. Any outstanding input VAT credit needs resolving before cancellation, since it cannot be used once the registration closes:
- Carried forward against a final output VAT liability
- Claimed as a refund from the Revenue Department, which can take several months where documentation needs review
Penalties for non-filing and director liability
Non-filing draws separate penalties from the Revenue Department and the DBD, and Thai law puts some of that exposure on directors personally rather than only on the company.
| Filing | Statutory Cap | Typical amount in practice | Additional surcharge |
|---|---|---|---|
| PP.30 (late or missing) | THB 2,000 (Section 90) | THB 300 within 7 days, THB 500 beyond | 1.5% per month on unpaid tax (Section 89/1), does not apply to a genuine nil filer. |
| PND 50 / 51 (late or missing) | THB 2,000 | THB 1,000 within 7 days, THB 2,000 beyond | Same 1.5% monthly surcharge, does not apply to a nil filer. |
On the accounting side, the company is required to prepare annual financial statements, have them audited by a licensed auditor, and submit the audited financial statements to the shareholders for approval within four months from the end of the financial year. Failure to comply with these requirements may subject the company to a fine of up to THB 20,000 under the applicable Thai laws. The company is also required to file the approved financial statements with the DBD within one month from the date of shareholders’ approval. Late or non-filing may result in additional penalties, with the amount depending on the nature and duration of the non-compliance. Penalties may also be imposed on the responsible director(s) in accordance with the applicable law and the DBD’s penalty/settlement schedule.
When to consider dissolving a dormant company
Dormant status works well when there is a genuine plan to reuse the company, whether to relaunch the business, hold intellectual property or act as an investment vehicle. It works less well as a default when there is no real intention to reactivate it, since the audit, tax and VAT obligations continue regardless of intent.
Weighing the decision means comparing the ongoing annual cost of staying dormant, covering bookkeeping, the audit and tax filings, against the one-off cost and timeline of dissolving the company. Dissolution in Thailand typically takes 45 to 90 days for a straightforward case with no debts and organised accounts, though it can extend well beyond that where tax clearance or creditor claims complicate the liquidation. Once the annual compliance spend outweighs the value of keeping the company registered, dissolution becomes the more practical route, and it draws a firmer line under director liability than an open-ended dormancy does.
Conclusion
Dormant status lets a business owner pause operations without giving up the company, and Thailand places no fixed limit on how long it can be held. What changes is not whether obligations exist but which ones apply: tax returns still go in as nil filings, a licensed CPA still signs off the accounts, VAT registration only needs keeping where it serves a purpose, and both the company and its directors carry penalty exposure for anything that lapses. Where those obligations no longer justify keeping the company on the register, dissolving it properly is usually the more practical way to close the chapter.
