In short
- Deductible VAT (input VAT) is the VAT you pay your suppliers. You subtract it from the VAT collected on your sales: VAT to be remitted = VAT collected − deductible VAT.
- It only covers goods and services needed for your business, and you must be able to produce the supporting documents, starting with the invoice.
- Only Luxembourg VAT is deductible in Luxembourg; VAT paid in another Member State is reclaimed from that State’s authorities.
- If your deductible VAT exceeds the VAT due, the surplus is carried forward to the next period or refunded.
The principle: VAT should not cost your business
VAT is a tax on final consumption. For a VAT-registered business it is meant to be neutral: the VAT you pay on business purchases comes back to you.
Guichet.lu puts it simply: input VAT is VAT paid to suppliers, and the deduction regime exists so that VAT does not increase the cost of goods and services and stays fully neutral for taxable persons. Each business pays the Registration Duties, Estates and VAT Authority (AED) the difference between the VAT collected on sales and the deductible VAT paid on business purchases.
If VAT is new to you, start with our guide to VAT in Luxembourg: rates, registration and returns. This article focuses on the other side of the calculation, what you can recover.
Worked example: one laptop, one quarter
A self-employed consultant buys a laptop for her business: EUR 1,500.00 excluding VAT. At the standard rate of 17%, the supplier’s invoice shows EUR 255.00 of VAT, EUR 1,755.00 in total. In the same quarter she invoices her clients EUR 5,000.00 excluding VAT, which means EUR 850.00 of VAT collected.
| Line | Amount |
|---|---|
| VAT collected on sales (EUR 5,000.00 × 17%) | EUR 850.00 |
| Deductible VAT on the laptop (EUR 1,500.00 × 17%) | − EUR 255.00 |
| VAT payable to the AED for the quarter | EUR 595.00 |
The EUR 255.00 is not lost: it directly reduces what she pays. The figures are illustrative; to check a calculation, use our Luxembourg VAT calculator.
The three conditions to check
- The purchase is for your business. According to Guichet.lu, the deduction only covers VAT on goods and services necessary for the operation of the business.
- You keep the invoice. To deduct input VAT, you must be able to provide all supporting documents (invoices, transport documents, payments, etc.) at the AED’s request. Invoices received must be kept for 10 years from their date of issue.
- It is Luxembourg VAT. Only Luxembourg VAT is deductible in Luxembourg: VAT paid to another taxable person in Luxembourg, VAT declared on intra-Community transactions and VAT declared or paid on imports.
A correct invoice is the basis of any deduction. To check yours, see the mandatory information on an invoice.
What about VAT paid abroad?
A hotel in Paris, a trade fair in Cologne: French or German VAT cannot be deducted on your Luxembourg return. Guichet.lu specifies that refunds of foreign VAT on costs incurred in another Member State must be requested directly from the relevant authorities of that State.
When the deduction is limited or not possible
| Situation | Deduction | What Guichet.lu says |
|---|---|---|
| Goods partly used privately | Partial | If goods or services are not fully linked to the business, a pro rata deduction must be determined |
| Purchase used for exempt activities | None | Input VAT cannot be deducted when the goods or services are used for exempt activities |
| You do not charge VAT on your sales | None | No deduction if the taxable person is not obliged to apply VAT to the revenue of its activity |
| Both taxable and exempt activities | Partial | VAT is only partly deducted, using an allocation key or a pro rata |
If you use the small-business exemption scheme or part of your activity is exempt, have your calculation method checked: the pro rata is adjusted later, especially for capital goods.
More VAT paid than charged: carried forward or refunded
The first months of activity, or a quarter with large investments, can produce a negative result. According to Guichet.lu, if input VAT is higher than the VAT due, the surplus can either be refunded or carried forward to the next taxable period to be deducted then.
- Carry forward: the surplus moves to future VAT returns of the same calendar year.
- Refund: in theory monthly if the amount is EUR 1,200 or more, otherwise annually provided the amount is higher than EUR 2.40.
When do you claim the deduction?
As a rule, the deduction is claimed on the VAT return for the period in which the VAT became payable. Exception: if you opted for the cash-accounting scheme (possible with annual turnover excluding VAT below EUR 500,000), the deduction is only allowed once the invoice has been paid.

Frequently asked questions
What is deductible VAT?
It is the VAT you pay suppliers on business purchases (input VAT). You deduct it from the VAT collected on your sales and only pay the AED the difference.
How is the VAT payable calculated?
VAT to be remitted = VAT collected − deductible VAT. Example: EUR 850 of VAT collected and EUR 255 of deductible VAT leave EUR 595 to pay.
Can I deduct VAT paid in another EU country?
Not on your Luxembourg return: only Luxembourg VAT is deductible there. A refund of foreign VAT is requested directly from the authorities of the Member State concerned.
What happens if my deductible VAT exceeds the VAT collected?
The surplus is either carried forward to the next period or refunded. Refunds are in theory monthly from EUR 1,200, otherwise annual above EUR 2.40.
Can I deduct VAT on goods I partly use privately?
Partly: when goods or services are not fully used for the business, you must determine a pro rata deduction.
