Cambodia: Procedures for Recording and Declaring Taxes on Transactions that Occur and are Recorded in Accounting Prior to Payment

Issued: 02 December 2025

The General Department of Taxation (“GDT”) issued Instruction No. 37705 on 2 December 2025 to provide comprehensive operational guidance on the accrual accounting basis for tax purposes in alignment with Cambodia’s International Financial Reporting Standards requirements. The Instruction clarifies how taxpayers must record and declare transactions—both income and expenses—that are incurred and recognized in accounting before actual payment.

Below is the summary of Instruction No. 37705

A. Accrued Expenses

Taxpayers recording accrued expenses must ensure that the supporting documents, tax treatment, and subsequent adjustments are handled in accordance with Cambodian tax regulations.

1. Documentation Requirements

Accrued expenses must be supported by a Purchase Voucher that includes, document name or description, document reference number and date, Account and sub‑account codes, Debit and credit amounts, Description of the transaction, Name, signature, and date of the preparer and approver.

This ensures proper audit support and validation of expense recognition.

2. Reporting in the Purchase Journal

All accrued expenses must be recorded in the Purchase Journal, including Voucher number, Date. Amount, Description.

This ensures accurate liability recognition in the accounting period.

3. Withholding Tax (WHT) and VAT Input Implications

  • For transactions subject to WHT, the taxpayer must declare the WHT in the monthly return at the time the expense is accrued.
  • Input VAT cannot be claimed until a valid tax invoice is received from the supplier.

4. Adjustment Upon Receipt of Actual Invoice

Once the supplier’s actual invoice is issued:

  • Accrued WHT > actual WHT:
    Excess WHT may offset the current month’s WHT payable; any remaining amount is carried forward.
  • Accrued WHT < actual WHT:
    The shortfall must be declared and paid in the current month.

B. Accrued Revenue

Accrued revenue must be supported and reported properly for tax purposes, including PTOI and VAT obligations.

1. Documentation Requirements

Accrued revenue must be supported by a Sale Voucher, containing similar required elements as a Purchase Voucher.

2. Reporting in the Sales Journal

Accrued revenue must be recorded in the Sales Journal, including Voucher number, Date, Amount, and Description.

This ensures revenue is recognized in the correct accounting period.

3. Prepayment Tax  on Income (PTOI) and VAT Output Treatment

  • Accrued revenue arising from business activities or subsidiary income is subject to PTOI.
  • VAT output is not recognized until the actual tax invoice is issued.

This aligns VAT liability with invoice issuance, not accrual.

4. Adjustment Upon Issuance of Actual Invoice

After issuing the actual invoice:

  • Accrued PTOI > actual PTOI:
    Excess PTOI may offset current month’s PTOI; any remaining balance is carried forward.
  • Accrued PTOI < actual PTOI:
    Additional PTOI must be declared and paid in the current month.
  • VAT output is based solely on the actual invoice amount.

The GDT has also issued Instruction No. 37706, which provides guidance on how to declare accrued revenue and expense transactions in the E‑Filing system.

If any taxpayer intentionally declares false accrued transactions purposely for reducing tax based, it will result in penalties being imposed by the tax administration in accordance with relevant tax law and regulations in force.
