Tax Authority Clarifies Per-Transaction Invoicing for Small Businesses Under 500 Million Dong in Annual Revenue

Household businesses in Can Tho raised questions with the Can Tho City Tax Department’s Sub-Office 2 about invoice eligibility under new rules effective from Government Decree No. 68/2025/NĐ-CP. Specifically, they asked whether businesses with annual revenue under 500 million dong can still purchase per-transaction invoices from the tax office when customers require invoices.

New eligibility rules for households under 500 million dong

The tax office response stated that, under Government Decree No. 68/2025/NĐ-CP, households with annual revenue under 500 million dong do not qualify to use electronic invoices and are no longer eligible to receive per-transaction invoices from the tax office. The tax office noted that this represents a complete change compared with the previous regime.

What if a household previously registered for electronic invoices?

Another question concerned households that had previously registered to use electronic invoices but, in 2026, their actual revenue is determined to be under 500 million dong. The Can Tho City Tax Office advised that in this case, the household business must suspend the electronic invoices that were previously registered.

The tax office also emphasized that household businesses should proactively review their revenue levels to follow the correct procedures and avoid later issues.

Ongoing monitoring and reporting requirement

Under Circular 152/2025/TT-BTC, households and individuals with annual turnover of up to 500 million dong continue to be required to monitor revenue for tax management using the S1a-HKD form. Revenue recording may be done on a per-transaction basis or as a daily revenue total, provided it fully reflects actual revenue.

This information is used by tax authorities to determine the scale of operations and the household’s tax obligations at any given time.

Purchases from other small households and invoice handling

For transactions where a household business buys goods from another household or individual business with annual revenue under 500 million dong, the seller typically does not issue invoices. In such cases, the buyer household may prepare a purchase ledger using the form specified in Circular 152/2025/TT-BTC.

The purchase ledger should include key details, including the seller’s name and address, the seller’s citizen ID or identifying information, and information about the goods purchased such as item name, quantity, and value, as well as the payment method.

Record retention for tax verification

The tax office guidance also highlighted that the buyer household should retain all payment documents and related records for these transactions. These documents will serve as evidence to support the legitimacy of costs if tax authorities conduct inspections or determine the household business’s tax obligations.
