Why VAT and e-invoicing matter
Vietnam VAT compliance is closely connected to invoicing. If the invoice is incorrect, issued late, missing required information or unsupported by proper payment documents, the tax consequences can affect both the seller and the buyer.
For foreign-owned companies, VAT and e-invoicing also affect cash flow. Output VAT must be declared and paid correctly, while input VAT deductions or refunds depend on proper invoices, eligible transactions and supporting documents.

Practical takeaway
VAT is not only a tax rate question. It is a document-control system involving contracts, invoices, bank payments, accounting records, tax filings and audit evidence.

VAT basics for foreign-owned companies
VAT generally applies to taxable goods and services supplied in Vietnam, imports and certain cross-border supplies. The applicable treatment depends on the transaction type, tax registration method, customer, product or service category and supporting documentation.
%
Output VAT
VAT charged on taxable sales, usually reflected in the company’s e-invoice and VAT declaration.
↩
Input VAT
VAT paid on eligible purchases, which may be deductible or refundable if conditions are satisfied.

Special treatment
Some exports, exempt supplies or non-taxable items may require different treatment and documentation.
Vietnam has continued updating its VAT framework, including changes under the new VAT Law effective from July 1, 2025 and temporary VAT reduction rules for eligible goods and services. Foreign-owned companies should confirm the current treatment before issuing invoices or claiming input VAT. :contentReference[oaicite:1]{index=1}
What is an e-invoice in Vietnam?
An e-invoice is an electronic invoice generated, stored and transmitted in a prescribed digital format. It is not just a PDF. It is part of Vietnam’s tax administration system and should be managed through approved processes and software.
E-invoices support tax authority monitoring, buyer verification, VAT declaration and accounting records. Companies need internal controls to make sure invoices are issued with correct information and matched to the underlying transaction.
| Area | What to control | Why it matters |
|---|
| Invoice timing | When the invoice is issued relative to delivery, service completion, payment or contract milestone. | Late or incorrect issuance can create tax and customer disputes. |
| Invoice content | Seller, buyer, tax code, description, amount, VAT rate, currency, date and required fields. | Incorrect invoice details can affect VAT deduction and accounting records. |
| Invoice type | VAT invoice, sales invoice, export invoice or other applicable invoice form. | The wrong invoice type can create downstream tax treatment problems. |
| System process | Software, digital signature, data transmission and storage. | E-invoicing compliance depends on system reliability, not manual correction later. |
| Corrections | Adjustment, replacement or cancellation process for errors. | Invoice mistakes should be corrected through proper procedures. |
Vietnam has continued expanding e-invoicing scope and technical requirements, including changes for foreign suppliers and digital-platform operators from 2026. :contentReference[oaicite:2]{index=2}
Input VAT: where many companies lose money
Input VAT deductions are valuable, but they are not automatic. A company may lose input VAT deductibility if invoices, payment evidence, tax treatment or business-purpose documentation are weak.
- Check whether the supplier invoice is valid and matches the actual transaction.
- Confirm the supplier’s tax information and invoice details.
- Maintain contracts, purchase orders, delivery evidence and payment records.
- Use non-cash payment where required for input VAT deductibility.
- Separate taxable, exempt and non-taxable business activities where relevant.
- Review export and cross-border documentation carefully before claiming VAT treatment.
- Reconcile invoice data with accounting records and tax declarations monthly.
The new VAT framework has changed some compliance fundamentals, and companies should review payment and documentation thresholds carefully before claiming input VAT. :contentReference[oaicite:3]{index=3}
Special issues for foreign-owned companies
Foreign-owned companies often face VAT and e-invoicing issues because their Vietnam accounting must connect with overseas contracts, group reporting, intercompany charges, foreign vendors and cross-border services.
🌐
Cross-border services
Foreign contractor tax, VAT treatment and invoice support should be reviewed before payment.
↔
Intercompany charges
Management fees, royalties, service fees and cost sharing need proper contracts and tax support.
📤
Export transactions
Export VAT treatment requires careful documentation, payment and delivery evidence.
Foreign digital suppliers and platforms
Foreign suppliers without a permanent establishment in Vietnam that conduct e-commerce or digital-platform business with Vietnamese organizations or individuals are increasingly affected by Vietnam’s VAT and e-invoicing framework. The VAT rate for certain digital/e-commerce services provided by foreign suppliers without a permanent establishment is reported as changing from 5% to 10% under the new framework. :contentReference[oaicite:4]{index=4}
Monthly VAT and e-invoice controls
Foreign-owned companies should not wait until the tax filing deadline to review VAT. A monthly process helps catch errors before they become audit or cash-flow problems.
| Control | What to review | Owner |
|---|
| Sales invoices | Invoice timing, VAT rate, buyer details, contract link and revenue recognition. | Accounting and sales operations |
| Purchase invoices | Supplier validity, invoice details, business purpose and payment evidence. | Accounting and procurement |
| Bank payments | Non-cash payment support for eligible input VAT and reconciliation with invoices. | Finance |
| Cross-border payments | Foreign contractor tax, VAT withholding and contract support. | Finance and management |
| VAT return preparation | Output VAT, input VAT, adjustments, carry-forward and supporting schedules. | Tax and accounting |
A company that is newly set up in Vietnam should implement these controls from the first month, not after the first audit.
Common VAT and e-invoicing mistakes
- Issuing invoices late or with incomplete buyer information.
- Using the wrong VAT rate because product or service treatment was not reviewed.
- Claiming input VAT without sufficient invoice, payment or business-purpose support.
- Failing to reconcile e-invoice data with accounting records and tax returns.
- Ignoring VAT issues in intercompany service fees, royalties or cost allocations.
- Using cash payments where non-cash payment evidence is required for input VAT deduction.
- Not reviewing export documentation before applying export-related VAT treatment.
- Waiting until year-end to resolve monthly invoice errors.
