How to validate the financial statement of your company?

All companies are required to prepare their financial statements for each financial year. The financial statement must be verified and notified by an approved auditor. The balance sheet must first be certified by the auditor of the company, approved by the shareholders and then filed with the Department Business Development (DBD) and the Revenue Department.

For a limited liability company, Article 1197 of the Thai Civil and Commercial Code states that the director is responsible for organizing the extraordinary annual general meeting of shareholders to approve the accounts within 4 months of the end of the fiscal year.

Article 1175 of the same code provides that the director must convene all shareholders registered in the register of shareholders within 7 days before the holding of the general meeting by letter with acknowledgment of receipt. The notice of meeting must include the following information: the place, day, time of the meeting and the agenda. This notice of the general meeting must also be published in a local newspaper at the latest seven days before the date fixed for the meeting.

The deadlines are extended to 14 days as soon as the general meeting deals with a special resolution.

Article 1197 of the Civil and Commercial Code provides that a copy of the financial statements must be sent to all shareholders at least three days before the general meeting. They must also be kept at the company’s head office for the same period for consultation.

When the general meeting is held, the shareholder, who cannot physically visit the site, may vote by proxy, provided that the proxy has been established in writing. Article 1188 of the Code provides that the proxy must be dated and signed by the shareholder and contain the following information:

1. The number of shares held by the shareholder
2. The name of the representative
3. The period for which the representative is appointed

Failure to comply with the rules relating to the convening or holding of the meeting with regard to the provisions of the Civil and Commercial Code is penalized by the invalidity of the resolution taken in violation of said provisions.

The maximum penalties that can be imposed for not having held an annual general meeting for the approval of the accounts within 4 months of the end of the financial year are a fine of 20,000 THB for the company, and a fine of 50 000 THB for administrators.

When should the financial statements be filed with the competent authorities?

Following the holding of the general meeting, the limited liability company has a period of one month from the date of the general meeting to file the financial statements approved with the Department Business Development (DBD) by the electronic filing system.

For example, if a company holds its general meeting on April 28, 2020, the last day to file its financial statements with the DBD will be May 29, 2020, because May 28, 2020 is a public holiday.

It must then proceed with the tax declaration using the PND 50 form to the Revenue Department within 5 months of the end of the financial year.

How is the declaration and payment of corporation tax carried out?

The declaration differs if the Thai or foreign company is doing business in Thailand or if the foreign company only receives income from Thailand.

As long as the company does business in Thailand, the company is required to make two declarations during the fiscal year: the annual declaration and the semi-annual declaration.

Thai and foreign companies doing business in Thailand are required to file their tax returns using PND 50 form within 150 days of their fiscal year end date. The payment of the Corporate Income Tax is concomitant with the filing of the tax declaration. Any company that transfers activities representing profits outside Thailand is also required to pay tax on the amount thus transferred within 7 days of the date of transfer via the PND 54 form provided for withholding tax.

In addition to the annual tax payment, any company subject to Corporate Income Tax is also required to make a semi-annual advance tax payment using the PND 51 form. The company is required to estimate its annual net profit as well as its tax liability and to pay half of the estimated amount of tax within 2 months of the end of the first six months of its financial year. The prepaid Corporate Income Tax is deductible from its annual tax liability.

For income paid to a foreign company not doing business in Thailand, the foreign company is subject to withholding tax by the payer at the time of payment. The payer must file the PND 54 declaration and make the payment to the tax authorities within 7 days of the month in which the payment is made.

When is it possible to obtain a tax credit?

For companies operating in Thailand, it is possible to obtain a tax credit when a tax has been deducted at source with regard to a service rendered, a dividend or interest paid or a rent perceived for example. The amount withdrawn will be credited during the annual tax declaration of the beneficiary company.

For income from countries that do not have a double taxation agreement with Thailand, foreign tax credits are allowed. These foreign tax credits are subject to certain criteria and conditions, and can be used up to the amount of Thai tax that would have been due if the income had been derived in Thailand.

What are the penalties for delay or failure to submit financial statements?

Failure to submit audited financial statements approved by the general assembly to the DBD within one month of approval is punished by a fine, the amount of which increases depending on the number of months late.

Below is the penalty table for a Thai limited liability company:

Number of months late Fine for the accountant (in baht) Fine for the director (in baht) Amount (in baht)
Less than 2 months late 1,000 1,000 2,000
Between 2 and 4 months late 4,000 4,000 8,000
More than 4 months late or no deposit 6,000 6,000 12,000

What are the penalties for late or non-reporting of income?

In the event of late declaration or absence of annual declaration, a late penalty of 1.5% of the tax payable per month is applied. Concerning the delay of the deposit and payment of the half-yearly declaration, it is sanctioned by a surcharge of 20% of the tax which must be paid.

Is there a tax consolidation regime for a group of companies?

Each company is taxed as a separate legal entity. Losses suffered by one subsidiary cannot be offset against profits made by another subsidiary. There is no tax consolidation. Losses can only be carried forward for a maximum period of five years.
