Cambodia has introduced clearer rules on who is responsible for unpaid taxes when a business changes hands, shares are transferred, or companies merge. The new regulation, signed by Deputy Prime Minister and Finance Minister Aun Pornmoniroth on July 29, 2026, sets out how tax liabilities are handled before and after these transactions and what buyers, sellers, shareholders and successor companies need to do.
The rules apply to taxpayers under Cambodia’s self assessment regime and require businesses involved in ownership transfers, share transactions or mergers to notify the tax administration and update their records within 15 working days of the transaction or approval date. The framework is designed to reduce uncertainty over outstanding tax debts and encourage businesses to settle their obligations before completing major ownership or structural changes.
Business Transfers Could Shift Tax Debts to New Owners
One of the most important parts of the regulation concerns the transfer of a business from one owner to another. The responsibility for outstanding taxes depends largely on whether the original owner properly settles their tax accounts before the transfer.
If the transferring owner applies to settle the business’s tax accounts, tax liabilities accumulated up to the date of the transfer remain the responsibility of the seller. The new owner would then generally be responsible only for tax obligations arising after taking over the business.
The situation changes if the seller does not settle the outstanding tax obligations. In that case, the acquiring owner may become responsible for all liabilities connected to the business, including debts that existed before the transfer. This makes tax due diligence an important part of any business acquisition in Cambodia.
Businesses Closing After a Transfer Still Face Tax Obligations
The regulation also addresses what happens when a company stops operating after transferring its business. A company that completes the required settlement procedures remains responsible for its outstanding tax debts.
However, if the business ceases operations without completing those procedures, the tax obligations can shift to the acquiring enterprise. Businesses that continue operating after transferring part or all of their operations also remain responsible for liabilities incurred up to the handover date.
For buyers, this means that completing a transaction is not simply a matter of signing a sale agreement. Checking the seller’s tax position and making sure the required procedures are completed could be critical to avoiding unexpected liabilities after the deal.
Qualifying Business Transfers May Avoid VAT
The new rules also provide an important VAT provision for qualifying business transfers. When the required notification procedures are properly followed, eligible transfers can be exempt from VAT.
Failure to meet the notification requirements, however, could result in a 10 percent VAT liability. This gives businesses another reason to ensure that tax administration procedures are completed on time rather than treating notification as a routine administrative matter.
Share Transfers Generally Limit Liability to Ownership Proportions
The rules also clarify tax responsibility in share transactions. In general, a shareholder’s liability is linked to their proportional ownership in the company.
This provides a different treatment from a direct business transfer, where an acquiring owner could potentially inherit broader outstanding obligations if the previous owner failed to settle them. For investors buying shares in a Cambodian company, understanding the company’s existing tax position remains important before completing a transaction.
The regulation also makes clear that shareholders may face responsibility in cases involving fraud or tax evasion, with liability potentially applying in proportion to their investment.
Mergers Transfer Outstanding Debts to the Surviving Company
Corporate mergers receive another clear treatment under the framework. When companies merge, the surviving company or newly established entity must assume all outstanding debts and obligations of the companies involved.
That means a merger does not simply combine businesses and assets while leaving previous tax liabilities behind. Outstanding obligations follow the corporate structure into the surviving or newly created company.
For companies considering mergers or restructuring, this makes tax and financial due diligence particularly important before the transaction receives final approval.
Sole Proprietors and General Partners Face Greater Exposure
The rules also highlight the difference between incorporated businesses and structures where owners or partners have unlimited liability. Sole proprietors and general partners can remain personally responsible for business obligations, meaning liability may extend to their personal assets.
This distinction is particularly important for business owners considering a transfer, restructuring or other ownership change. The legal form of the business can directly affect how far tax liabilities may reach.
What the New Rules Mean for Cambodian Businesses?
The new framework gives businesses a clearer roadmap for dealing with tax obligations during ownership changes, share transactions and mergers. More importantly, it makes the timing of tax settlement and notification a key part of completing these transactions safely.
For buyers, investors and companies planning mergers, the message is straightforward: do not treat tax liabilities as an issue to address after a deal is completed. Reviewing outstanding obligations, completing settlement procedures and notifying the tax administration within the required timeframe can help reduce the risk of inheriting unexpected debts or facing additional VAT liabilities.
Conclusion
Cambodia’s updated tax liability rules bring greater clarity to an area that can become complicated when businesses change ownership or corporate structures. The rules establish different responsibilities for business transfers, share deals and mergers while making clear that unpaid tax obligations do not necessarily disappear when ownership changes.
For Cambodian business owners, investors and companies planning acquisitions or mergers, understanding these rules before signing a transaction could be just as important as negotiating the purchase price. Proper tax checks and timely compliance can help prevent an ownership change from turning into an unexpected financial burden.
