Four invoices arrive in the same month: a laptop, shared internet, a customer dinner and fuel for a company car. All show Estonian VAT, but that does not make all of the tax deductible. The result depends on how each purchase is used, whether the company makes taxable or exempt supplies, which special restriction applies and whether the evidence is ready when KMD is filed.
In my 15+ years in Estonian accounting, I have found that the safest review starts with the purpose of the purchase, not the VAT line. In practice, input VAT in Estonia is decided purchase by purchase. This article follows those four invoices from receipt to KMD and shows where the deductible amount changes. It complements our invoice and reverse-charge articles without repeating their primary intent.
Start with registration, taxable use and evidence
Under § 29 of the Value-Added Tax Act, the core right belongs to a taxable person acquiring goods or services for taxable business supply. A supplier's VAT line is therefore only the starting point. A company that is not VAT-registered normally has no current KMD deduction, and a registered company cannot deduct a purchase used for exempt supply or private consumption as if it were fully taxable business use.
The EMTA explanation of deductible input VAT also covers import VAT, intra-Community acquisitions and VAT self-assessed on qualifying services from foreign suppliers. Each route needs its own document: an invoice for an ordinary domestic purchase, customs evidence for an import, or the purchase document and calculation for reverse charge.
| Question | If yes | If no |
|---|---|---|
| Was the buyer VAT-registered for the relevant transaction? | Continue to the use test | No ordinary KMD deduction |
| Does the purchase support taxable business supply? | Full or partial deduction may be available | Block the non-business or exempt part |
| Is the required invoice or other evidence available? | Apply the timing rule | Wait until the evidence is received |
| Does a special restriction apply? | Use that restriction | Apply the general rule |
Trace four invoices instead of using one percentage
Assume a VAT-registered consultancy makes only taxable supplies. It buys a laptop for EUR 1,000 plus EUR 240 VAT and uses it only for client work. It also receives an internet invoice for EUR 100 plus EUR 24 VAT, supported by a 60% business-use allocation. Those two documents produce EUR 240 and EUR 14.40 of deductible input VAT.
The customer dinner costs EUR 200 plus EUR 48 VAT. That VAT is blocked by the guest-reception restriction even though the meeting has a genuine commercial purpose. Fuel for a passenger car costs EUR 100 plus EUR 24 VAT; if private trips are allowed and no lower taxable-supply ratio applies, the usual 50% limit leaves EUR 12 deductible. Across the four invoices, the company deducts EUR 266.40 rather than the EUR 336 shown as total VAT.
| Purchase | VAT on invoice | Deductible VAT | Reason |
|---|---|---|---|
| Business-only laptop | EUR 240 | EUR 240 | Taxable business use |
| Internet, 60% business use | EUR 24 | EUR 14.40 | Direct mixed-use allocation |
| Customer restaurant bill | EUR 48 | EUR 0 | Guest-reception restriction |
| Mixed-use passenger-car fuel | EUR 24 | EUR 12 | General 50% car limit |
Non-deductible VAT is not lost from the accounts: it normally becomes part of the expense or asset cost. What changes is that it does not reduce the VAT payable on KMD.
Separate prohibited VAT from VAT that only needs allocation
EMTA's input-VAT restrictions block VAT on goods and services connected with receiving guests and on meals or accommodation for employees, except employee accommodation on a business trip. A valid customer meeting does not override this rule. A staff lunch may also create a separate fringe-benefit question; income-tax classification and VAT deduction are different tests.
Mixed use is different from an absolute prohibition. The EMTA partial-deduction guidance requires direct classification where possible. If electricity, internet or another shared cost supports both business and private use, document a reasonable cost-based split. If the business itself makes both taxable and exempt supplies, a second taxable-supply proportion may reduce the business part further.
| Use pattern | VAT approach | Evidence to retain |
|---|---|---|
| Only taxable business activity | Full deduction unless a restriction applies | Invoice and business purpose |
| Business and private use | Deduct the supportable business share | Allocation method and source data |
| Taxable and exempt business supply | Apply the relevant partial-deduction method | Supply calculation and year-end review |
| Guest meal or entertainment | No input VAT deduction | Attendees and purpose for other tax treatment |
Treat the passenger-car rule as a ceiling, not a promise
For an ordinary category M1 passenger car used for both business and private trips, the EMTA passenger-car guidance generally limits input VAT on purchase, lease, fuel, maintenance and similar running costs to 50%. If part of the company's activity is exempt, the deductible percentage can be lower than 50%.
A full deduction is possible only when a statutory exception applies or the car is directly necessary for business and used exclusively for business purposes with credible controls. Do not infer 100% use from a policy sentence alone. Access, parking, trip records and the actual ability to take private journeys should tell the same story. The separate fringe-benefit calculation for private use does not replace the VAT analysis.
Post the deduction in the period supported by the invoice
According to the EMTA timing rule, the deduction generally follows the tax period in which the seller's supply arose, provided the invoice has arrived by the time the return is submitted. If the invoice is still missing at filing, deduct the VAT in the period when the invoice is received rather than inventing evidence for the earlier month.
Before KMD, reconcile the purchase ledger to invoice status, use classification, blocked categories and partial-deduction percentages. Record why an amount was fully deducted, limited or blocked. If the use of a fixed asset changes, a later adjustment may be required, including a five-year adjustment period for most fixed assets and ten years for immovables. That is a continuing control, not a one-time invoice decision.
- Confirm the company's VAT status and the supplier's tax treatment.
- Link the purchase to taxable, exempt or non-business use.
- Check the invoice, customs document or reverse-charge evidence.
- Apply any reception, passenger-car or partial-deduction restriction.
- Reconcile the approved amount to KMD and retain the calculation.
I do not approve input VAT from the account name alone. 'Office costs' can contain a fully deductible laptop, partly deductible internet and a completely blocked restaurant bill. The short note explaining purpose and allocation is often more valuable than a long month-end reconstruction.
A reliable input-VAT decision has four parts: registration, taxable business use, valid evidence and special restrictions. The VAT printed on an invoice is not the answer. The answer is the supportable amount after those tests.
If your purchase ledger mixes private use, exempt activity, cars and overseas suppliers, send a sample month through the AccRes contact form before the next KMD is filed.
