How to Account for Invoice Discounts as a Freelancer in the Netherlands (2026)

What counts as a discount on a Dutch freelancer invoice?

For Dutch VAT, a discount lowers the taxable amount when the customer obtains the reduction at the time of supply or earns an early-payment discount. A freelancer normally calculates VAT on the net consideration, not the pre-discount list price. In 2026 that usually means 21% VAT, sometimes 9%, and 0% or reverse charge only in specific cross-border cases.

A discount only changes tax correctly when the discount is visible in the invoice, agreement, or later credit invoice (creditfactuur). For most Dutch freelancers, the practical rule is simple: revenue follows the amount the client must actually pay for the service before or after a justified correction.

If you charge Dutch VAT, calculate the VAT over the discounted fee, not over a higher reference price. If you work under the [VAT returns guide for freelancers in the Netherlands](/knowledge-hub/vat-returns-netherlands-expat-freelancer-guide), the discounted amount flows into the same VAT return (BTW-aangifte) period as the invoice unless you later issue a correction. If you use the KOR, the discount still lowers turnover, but there is no output VAT line.

• Trade discount: reduce the net sales amount before applying 21% or 9% VAT.
• Volume discount: record lower revenue once the customer qualifies for the lower price.
• Early-payment discount: record the lower amount only if the customer meets the payment condition.
• Post-sale rebate: issue a credit invoice and reduce both revenue and VAT for the discount amount.
• Refund after a complaint or return: treat the refunded amount as a negative sale, usually with a credit invoice.

How should a freelancer show discounts on an invoice?

A discount should appear on the invoice in a way that makes the taxable amount traceable per VAT treatment. In practice, a Dutch freelancer should show the original fee, the discount line or net discounted fee, the VAT rate of 21% or 9% if applicable, and the final amount due. If a Dutch invoice (factuur) is required, it is normally issued by the 15th day after the month of supply.

A compliant Dutch invoice still needs the standard data points even when you give a discount. That means your legal or registered trade name, addresses, invoice number, invoice date, service date, description, and the amount per VAT rate or exemption. A discount is safest when it is shown before the VAT total, so the customer and the Belastingdienst can see the net basis immediately.

For EU business services where VAT is reverse charged, you do not show Dutch VAT, but you still show the discounted remuneration and the wording 'btw verlegd'. If you use the KOR, you show no VAT at all and state that a VAT exemption applies. For general bookkeeping hygiene, keep the discounted invoice together with the offer or contract that explains why the reduction was granted.

• Show the discount before the VAT total, not only as a payment note.
• State the net fee after discount for each applicable VAT treatment.
• Use 21% or 9% VAT only on the discounted taxable amount.
• For reverse charge, add 'btw verlegd' and the customer's VAT ID.
• For KOR invoices, show no VAT and mention that a VAT exemption applies.
• Keep the invoice date within the normal deadline: no later than the 15th day after the month of supply.

What happens to VAT if you offer an early-payment discount or charge for late payment?

Early-payment discounts and late-payment surcharges do not work the same way for VAT. If the customer obtains the discount at payment, Dutch VAT can follow the lower amount, but missed discounts or late-payment surcharges can create additional VAT later. At 21% VAT, a late surcharge of €121 contains €21 VAT because the tax fraction is 21/121.

The safest workflow is to decide whether you discount first or charge extra later, and then document only one method. If you show a conditional early-payment discount on the invoice and the customer pays late, you owe VAT on the lost discount in the VAT return (BTW-aangifte). If you instead invoice the full amount first and later allow a discount, use a credit invoice so both parties correct VAT with the same document.

How do you treat post-sale discounts, credit notes, and VAT return corrections?

A post-sale discount should normally be handled with a credit invoice (creditfactuur) that refers back to the original invoice and shows the negative amount of revenue and VAT. The correction belongs in the period of the credit invoice or, if a return was already wrong, through the Dutch VAT correction process. You can correct Dutch VAT returns for up to 5 years after the relevant calendar year.

Credit invoices matter because they synchronise your books, your customer's input VAT, and your VAT return. If you serve EU business customers and you already filed ICP and VAT returns, Belastingdienst guidance says a credit invoice can require a negative correction in the new ICP period and the same period's VAT return. Keep the original invoice, the credit invoice, and the reason for the price reduction in one file.

• Reference the original invoice number and date on the credit invoice.
• Reduce revenue by the net discount amount and reduce output VAT by the related VAT amount.
• Book the correction in the period of the credit invoice unless a filed return needs a formal correction.
• Use the Dutch VAT correction route if the earlier return is already inaccurate.
• For EU B2B supplies already reported in ICP, include the negative adjustment in the relevant follow-up filing.

How do supplier discounts affect your costs and input VAT?

Supplier discounts reduce your deductible business cost and can also reduce input VAT. You may deduct input VAT when you receive a valid invoice, but if the supplier later refunds part of the price, grants a rebate, or you leave the invoice unpaid too long, you must repay the excess input VAT. The standard Dutch one-year rule applies if a purchase invoice is still unpaid 1 year after its due date.

On the purchase side, the bookkeeping rule is the mirror image of sales. A lower final price means a lower expense base, and any VAT refund or credit note reduces the input VAT you may keep. If you later pay an invoice after reversing the VAT because of the one-year rule, you may deduct that VAT again in the return for the later period. The same logic matters for foreign invoices where Dutch VAT was self-accounted under reverse charge.

• On receipt of the original invoice, book the cost and deduct the input VAT if the invoice is valid.
• If the supplier grants a rebate later, book a reduction of the cost and a reduction of input VAT.
• If you recover part of the purchase price, repay the over-deducted VAT in the next VAT return.
• If the invoice remains unpaid 1 year after the due date, reverse the excess input VAT.
• If you pay later after reversing, claim the VAT again in the return for the payment period.

What changes if you use the KOR or invoice EU business clients?

The KOR and EU business invoicing change the VAT mechanics, but not the discount logic. Under the small-business scheme (kleineondernemersregeling, KOR), turnover up to €20,000 per calendar year can qualify for the Dutch VAT exemption, so discounts reduce turnover but no Dutch VAT is charged. For many EU B2B services, you invoice the discounted amount without Dutch VAT, add 'btw verlegd', and report the turnover under the EU reporting rules that apply to the service.

KOR users still need an orderly sales record because the discount lowers the turnover that counts toward the €20,000 annual threshold. KOR users also cannot deduct VAT on business costs, including foreign VAT, so a supplier discount mainly changes the cost amount rather than a VAT recovery position. That makes discount tracking simpler on sales but potentially more expensive on purchases.

For EU business clients, match the discounted amount on the invoice and the VAT return and use the customer's checked VAT number before relying on reverse charge treatment. For related cost tracking, see the [deductible expenses guide for freelancers in the Netherlands](/knowledge-hub/deductible-expenses-freelancers-netherlands), especially if you combine cross-border work with supplier rebates.

• KOR: no Dutch VAT on the invoice, but the discount still lowers turnover.
• KOR threshold: once annual turnover exceeds €20,000, the exemption ends immediately.
• EU B2B services: invoice the discounted amount and add 'btw verlegd'.
• Include both VAT IDs on many EU B2B service invoices.
• Keep invoice totals consistent with the VAT return and any ICP filing that applies.
