The Hidden VAT Cost of Skipping an ATA Carnet
One of the situations our team unexpectedly encounters in providing accounting services in Thailand is when a client applies for a VAT refund, only to discover that a significant portion of the input VAT recorded in the accounts relates to goods that were temporarily imported for an exhibition or demonstration without using an ATA Carnet.
The VAT balance often remains on the balance sheet for months, or even years, not because the company is ineligible to recover it, but because no one connected the accounting implications back to the original customs transaction.
What is an ATA Carnet?
An ATA Carnet is an internationally recognised customs document that functions as a passport for goods temporarily entering another country. Instead of completing the normal import and export formalities and providing a customs guarantee, eligible goods may be admitted under a Carnet and subsequently re-exported using the same document.
Subject to the customs laws and procedures of the importing country, goods imported under a valid ATA Carnet are generally admitted without payment of import duties and import taxes, including import VAT where applicable. A Carnet is normally valid for up to one year from its date of issue and may be used in participating countries that have adopted the ATA Carnet system.
As a general rule, ATA Carnets are intended only for specific categories of temporary imports. Whether a particular shipment qualifies ultimately depends on the applicable customs legislation and the interpretation of the customs authorities in the countries involved.
Purpose
- Commercial samples
- Goods for trade fairs and exhibitions
- Professional equipment, such as filming equipment, broadcasting equipment, scientific instruments, or specialised tools
Condition of the Goods
The goods are generally expected to be non-perishable and to be re-exported in substantially the same condition in which they were imported. Goods that are sold, distributed, or consumed during the event, such as promotional materials, giveaways, brochures, or food samples, typically do not qualify, although the precise treatment depends on the applicable customs rules.
Timing
The goods are generally required to be re-exported within the validity period of the ATA Carnet, which is typically up to one year from the date of issue.
Eligible Countries
ATA Carnets may generally be used only where both the exporting and importing countries participate in the ATA Carnet system, subject to each country’s scope of acceptance and applicable customs regulations.
Where Companies Get Caught Out
The limitations above are precisely where many companies encounter unexpected tax consequences.
If any of the conditions for using an ATA Carnet are not met, or if a Carnet is not used where one would have been appropriate, the shipment generally falls back into the ordinary customs import procedures, together with the corresponding duty and VAT consequences.
In practice, this often occurs when equipment is brought into Thailand temporarily for a trade fair, product demonstration, testing, or similar business purpose without an ATA Carnet. The goods are processed through the normal customs import procedures on arrival and through the normal export procedures when they leave Thailand. Import duty and import VAT(where applicable) are paid at the time of import, even though the goods are not intended for sale in Thailand and will later be re-exported.
From an accounting perspective, the company records the import VAT as input tax and naturally expects to recover it through the normal VAT process.
However, unlike inventory imported for sale, a temporary import often has no corresponding taxable sale in Thailand that generates output VAT. As a result, the input VAT may remain outstanding on the balance sheet and, when included in a VAT refund claim, frequently requires additional supporting documentation.
By the time a VAT refund is reviewed, however, the logistics file may already have been closed, making it considerably more difficult to reconstruct the audit trail months later.
A Practical Example
We encountered this situation with a retail distributor that temporarily imported high-value products into Thailand for a trade exhibition before re-exporting them after the event.
At the time, the shipment was treated as a routine logistics matter rather than a transaction with accounting and tax implications.
The import VAT remained as a VAT refund receivable for almost a year, supported only by the original import documentation. Every subsequent request for additional evidence required the finance team to trace a shipment that the logistics department had long since regarded as completed.
Had an ATA Carnet been used where appropriate, much of that administrative burden, and the unnecessary cash flow impact, could likely have been avoided.
What We Do Differently
Our approach now has two parts.
First, we keep goods imported for resale completely separate from goods imported solely for temporary purposes such as exhibitions, demonstrations, repairs, or testing. These transactions follow entirely different VAT and documentary trails and should not be treated as though they are part of the same accounting cycle.
Second, we prepare a dedicated working paper for every temporary import, recording:
In practice, this schedule becomes the bridge between the customs documentation and the accounting records, allowing the finance team to demonstrate a complete audit trail from import through re-export whenever questions arise.
The purpose of the working paper is not merely administrative efficiency.
Why the working paper matters
Where a company cannot adequately demonstrate that the goods re-exported are the same goods that were originally imported, the Revenue Department may question the VAT treatment adopted and request further supporting evidence. Depending on the facts of the case, insufficient documentation may also give rise to broader VAT or corporate tax issues.
Maintaining a complete and traceable record from import through re-export significantly reduces that risk.
The Accounting Conversation Should Start Before the Shipment
In many multinational groups, decisions to temporarily import equipment into Thailand are made by operations, engineering, marketing, or sales teams, often with very little lead time.
The accounting and VAT implications are rarely part of that initial discussion.
By the time the finance team becomes involved, the shipment is often already in transit, leaving limited opportunities to optimise the customs and VAT position.
For that reason, we now encourage all foreign-owned clients to notify us before arranging any temporary import into Thailand.
Where an ATA Carnet is available, we can help determine whether it is appropriate for the shipment.
Where it is not, we can establish the necessary VAT treatment and documentation trail from the outset, making future VAT recovery significantly more straightforward and reducing the likelihood of unnecessary tax queries.
It is a relatively small step in the overall accounting process, but one that can prevent avoidable cash flow issues, minimise administrative burdens, and keep the balance sheet free from VAT balances that should never have remained outstanding in the first place.
