How to remove VAT from a price in Luxembourg

Published February 8, 2026 · 2 min read

Why you cannot just subtract 17% from a gross price in Luxembourg, and the correct formula for extracting VAT.

Why subtracting 17% gives the wrong answer

The tax was calculated on the net price, not on the gross price. Taking 17% off the gross price removes too much. The correct approach is to divide the gross price by 1.17, which returns the net price exactly.

Worked example

Here is the calculation with sample figures. Change any number in the Luxembourg Reverse VAT Calculator to run your own.

The tax fraction

If you only need the tax portion, multiply the gross price by 0.1453. That fraction, the rate divided by 100 plus the rate, is sometimes called the tax fraction, and it is useful when you reconcile receipts that only show tax-inclusive totals.

Where this comes up

Expense claims, receipts from shops in Luxembourg, marketplace payouts and quotes given "all in" all need the tax extracted before you can record the net cost correctly in your books.

Quick reference at 17%

Common amounts in Luxembourg, worked both ways: adding tax to a net price, and extracting it from a price that already includes tax.

How Luxembourg compares

Standard rates on file for other countries. A difference of a few points matters most on high-value purchases and on cross-border sales.

Using the calculator step by step

1. Open the Luxembourg Reverse VAT Calculator.
2. Type your figures into the numbered lines. Results update as you type.
3. Check the rate field. It starts at 17%; change it if a reduced rate, local surcharge or exemption applies to you.
4. Read the result on the receipt panel, and use the formula shown under it if you need to explain the figure to a client or colleague.

Key terms

Marginal rate

The rate applied to the next unit of income. It decides how much of a raise or a deduction you keep.

Taxable income

Income left after allowances and deductions, on which the tax rates are applied.

Zero rate

A rate of 0% on a taxable supply. Unlike an exemption, the seller can usually still reclaim tax on costs.

Tax credit

An amount subtracted directly from the tax bill, worth its full face value.

Standard rate

The rate that applies to most goods and services unless a specific reduced rate, zero rate or exemption applies.

Common mistakes to avoid

• Subtracting 17% from the gross price instead of dividing by 1.17.
• Reclaiming tax on receipts that do not show a valid tax breakdown.
• Recording gross amounts as costs and then reclaiming the tax a second time.
