GDT tax deregistration in Cambodia

In 3 bullets

• Closing a company in Cambodia starts with tax deregistration: a request to close the tax file with the GDT, settling all returns and liabilities (TOI, VAT, ToS, withholding tax, patent tax), then a closing audit.
• After the audit, the GDT issues a tax clearance certificate (certificate of tax compliance) — the document the Ministry of Commerce (MoC) requires before it strikes the company off the register.
• In practice, allow 6 to 12 months: the tax audit is by far the longest phase. The law requires notifying the GDT within 15 days of dissolution (Article 203, Law on Taxation 2023).

When tax deregistration is mandatory

As soon as you permanently cease the activity of a tax-registered entity (Co. Ltd., branch, sole proprietorship…), you must close its tax file. Until that is done:

• the filing obligations keep running (monthly return even at zero, annual TOI return, annual patent tax);
• penalties and interest pile up on missed returns;
• the company cannot be struck off at the MoC.

Legal framework

• Law on Taxation 2023 — Article 203: the taxpayer must notify the tax administration within 15 days of the permanent dissolution of the business.
• GDT Instruction on the procedure for permanent business dissolution (issued 17 September 2024): sets out the forms and the filing channel (online or in person).
• The GDT Prakas and instructions, published at tax.gov.kh, govern the procedural detail — check the latest version before filing.

The tax-deregistration steps

1. Close the books and bring returns up to date

Before filing the request, the GDT Instruction requires you to:

1. Close the accounting books at the cessation date.
2. File all monthly returns up to the dissolution date.
3. File the annual Tax on Income (TOI) return for the short final period (1 January to the cessation date).

See the full calendar in the GDT tax returns guide.

2. File the dissolution / file-closure request

Two channels under the 17 September 2024 Instruction:

• Online via the registrationservices.gov.kh single-window portal.
• In person at the tax administration, using Form 103, signed by the director, manager, owner or an authorised representative.

Documents to attach:

• Notification of permanent dissolution.
• Permanent dissolution business form (Form 101).
• Receipt for the KHR 1,000,000 stamp duty on the dissolution legal documents.
• In practice the GDT also asks for the VAT certificate and the patent tax certificate to be returned, plus the latest filed return.

After filing, you receive a letter certifying receipt of the request by the tax administration.

3. Settle the final period and clear liabilities

You file and pay the final-period taxes, which typically include:

• the final VAT (and recovery of any input-VAT credit);
• the prepayment of profit tax (TOI prepayment);
• withholding tax (WHT);
• Tax on Salary (ToS) and fringe benefit tax;
• the current-year patent tax.

In parallel: asset liquidation, settlement of debts, closing entries.

4. Undergo the closing audit

This is the key step — and the longest. A preliminary audit is run by an appointed GDT auditor, whether or not the company is up to date with its obligations. In some cases a comprehensive audit is also required. Prepare every supporting document: monthly and annual returns, leases, invoices, statements, financial statements.

5. Obtain the tax clearance certificate

Once the audit is closed and all liabilities settled, the GDT issues the tax clearance certificate (sometimes called the certificate of tax situation / tax compliance). This is the document that unlocks the next stage: the MoC requires it to strike the company off the commercial register.

6. Strike off at the MoC (next step, outside the GDT)

With the tax clearance certificate in hand, you file the dissolution application at the commercial register (MoC), which publishes a public notice and then issues a certificate of dissolution / closing. Detail in the liquidation guide.

Common pitfalls

FAQ

How long does tax deregistration take in Cambodia?

In practice, 6 to 12 months, the closing audit being the longest phase. No published text fixes the audit duration: it depends on the GDT office, the number of years to review and the state of the bookkeeping. Confirm case by case.

Can I close a company without paying patent tax arrears?

No. The closing audit quantifies all unfiled returns and patent tax on the open periods, plus penalties and interest. The tax clearance certificate is only issued once everything is settled.

What is the difference with liquidation at the MoC?

Tax deregistration (GDT) closes the tax file and results in the tax clearance certificate. Liquidation / dissolution (MoC) strikes the company off the commercial register and results in the certificate of dissolution — it requires the GDT certificate first. See the liquidation guide.

Must I notify the GDT even if the company never traded?

Yes. A tax-registered company remains liable for its returns and patent tax until it is struck off. Even “dormant”, it must follow the tax-deregistration procedure to be closed properly.

How long must I keep records after closure?

At least 10 years: financial statements, books and supporting documents. The GDT can ask to inspect them even after deregistration.
