In a tax finalization inspection record, one request line silences the whole accounting room: ‘explain the service, entertainment and support expenses without full invoices and vouchers’. Everyone understands what those expenses are in operating reality, and the inspection team understands too. The question is no longer naming, but the stacked legal consequences: the tax layer — disallowance, arrears collection and fines; the administrative layer — false-declaration penalties; and the criminal layer — when a ‘facilitation’ line in the books is read as bribe money under Article 364 of the Penal Code. This article handles exactly that working session: how to answer the inspection team without locking oneself into the next layer, and how to clean the books after the finalization round ends.
The Tax Fate of the Expense: Deductibility Conditions and the Disallowance Mechanism
The Law on Corporate Income Tax 67/2025/QH15 sets three simultaneous conditions for a deductible expense: actually incurred and related to production and business activity; supported by sufficient lawful invoices and vouchers; and paid non-cash for transactions at the statutory threshold. An expense called ‘facilitation’ usually breaks all three: no invoice because its nature admits no invoice, no provable business relation because its true purpose cannot be written down, and cash payment. At finalization, the inspection team disallows these expenses from deductible costs, redetermines taxable income and collects the shortfall plus late-payment interest of 0.03% per day under the Law on Tax Administration. The consequence spreads to value-added tax: input invoices attached to a disallowed expense (if any) are also reviewed for credit. The point to understand is that disallowance by itself is a tax conclusion; it says nothing about the expense’s criminal character — the two assessments run on two different files.
From Disallowance to Penalty, and the Bribery-Characterisation Boundary
The second layer is the penalty for false declaration leading to a tax shortfall: a 20% fine on the under-declared tax under the tax and invoice penalty decree, applied where the filing put ineligible expenses into deductible costs. The third layer — criminal — opens only where evidence shows the expense was in substance giving or promising a benefit to a person with position and authority so they would do or omit an act within their responsibility, under Article 364 of the Penal Code on bribe-giving; at that point the matter leaves the tax inspection team for the investigators, and the individuals who decided the expense bear personal liability. The dividing factor between ‘non-deductible expense’ and ‘bribe money’ lies not in the name in the books but in the recipient, the purpose and the real money flow. Because of this boundary, the explanation session with the inspection team must be prepared as a lawyer-attended working session: answer the tax part precisely, provide vouchers within the inspection scope, and do not ‘explain verbally’ into describing transactions with individual officials outside the file — every surplus description becomes a signed working record.
Cleaning the Books after Finalization: a Roadmap Creating No New Traces
Proper book-cleaning has four steps in order. Step one is self-reviewing every period still inside the inspection limitation, listing every expense of the same kind and quantifying the arrears and penalty risk per period — before the authority extends inspection to other periods. Step two is supplementary filing for periods not yet under a published inspection decision under the Law on Tax Administration mechanism, because voluntary supplementation before that point is a clear sanction-mitigating factor compared with being detected. Step three is honest accounting treatment of the settled part: recording the disallowed amounts and arrears duties in the books per the inspection conclusion, and absolutely not ‘recycling’ old expenses into new ones with purchased invoices — invoice trading turns a tax problem into an independent criminal case. Step four is locking the future by procedure: a prohibited-expense catalogue, approval thresholds and voucher requirements for entertainment and service expenses; mandatory non-cash payment channels; and retraining the sales and project teams — where these expenses usually originate — on the boundary between lawful business cost and bribe-giving.
Frequently Asked Questions
Is this expense deductible?
Almost never, for an expense that is genuinely ‘facilitation’. The Law on Corporate Income Tax 67/2025/QH15 allows deduction only for expenses actually incurred for production and business, with sufficient lawful invoices and vouchers, and non-cash payment at the threshold transactions. An expense with no invoice, no provable business purpose and cash payment breaks all three conditions and will be disallowed at finalization — the default tax conclusion, before any question of its criminal character.
Will it be disallowed and fined?
Yes, in layers. Layer one is disallowance, collection of the tax shortfall and late-payment interest of 0.03% per day under the Law on Tax Administration. Layer two is the false-declaration penalty at 20% of the under-declared tax under the tax and invoice penalty decree. Both layers apply on the tax file; they do not automatically turn the expense into bribe money, and the enterprise should close the matter at the tax layer with voucher-based explanation and proper supplementary filing instead of letting the file drift into another assessment.
Can it be treated as bribery?
When evidence shows the expense was in substance giving or promising a benefit to a person with position and authority to do or omit an act within their responsibility — constituting bribe-giving under Article 364 of the Penal Code. The deciding factors are the recipient, the purpose and the real money flow, not the name in the books. Where this layer is suspected, the tax explanation session must involve counsel and every statement must be controlled as potential testimony, because the working record with the inspection team can be transferred to investigators.
How can the books be cleaned up?
In four steps creating no new traces: self-review every period inside the inspection limitation and quantify the risk; voluntarily supplement filings for periods not yet under a published inspection decision under the Law on Tax Administration to earn the mitigating factor; honestly record the disallowed amounts and arrears duties per the inspection conclusion, absolutely never buying invoices to legitimise old expenses; and lock the future with a prohibited-expense catalogue, approval thresholds, voucher requirements and non-cash payment channels for all entertainment and service expenses.
