KIA investment deduction in the Netherlands (2026): rules, thresholds, and claiming steps

What is the KIA (kleinschaligheidsinvesteringsaftrek) and who can claim it in the Netherlands in 2026?

The KIA (kleinschaligheidsinvesteringsaftrek) is an investment deduction that reduces business profit for tax purposes when a business invests in qualifying business assets. In 2026, the total qualifying investment must be between €2,901 and €398,236, and each asset must cost at least €450. The deduction is claimed in the annual income tax or corporate tax return for the investment year.

In the Netherlands, many freelancers (ZZP’ers) run a sole proprietorship (eenmanszaak) and report profit in the annual income tax return (inkomstenbelasting). Browse the [Knowledge Hub](/knowledge-hub) for more freelancer accounting guides. The KIA is a profit deduction: it reduces taxable profit, which can reduce the tax due for that year.

The KIA is based on the total qualifying investment in the calendar year, not on one purchase. For KIA, the asset does not need to be new, but the asset must be a business asset (bedrijfsmiddel) and must not fall under an exclusion list. The KIA table sets the deduction amount for 2026.

• You are an entrepreneur for Dutch income tax or corporate tax purposes.
• Your total qualifying investment in 2026 is at least €2,901 and no more than €398,236.
• Each qualifying business asset has an investment amount of €450 or more.
• The business asset is intended for business use (not mainly private use).
• Excluded items (for example land, residential property, goodwill, and many passenger cars) are not included in the total.
• You claim the deduction in the tax return for the year of investment and keep contracts and invoices as evidence.

How much KIA can you deduct in 2026, and what is the maximum?

In 2026, the KIA depends on the total qualifying investment in the year. If the total is €2,901–€71,683, the KIA is 28% of the investment. If the total is €71,684–€132,746, the KIA is a fixed €20,072. If the total is €132,747–€398,236, the KIA is €20,072 reduced by 7.56% of the amount above €132,746, and it is 0 above €398,236.

The KIA is calculated on the total qualifying investment amount for the year. Example: if the total qualifying investment is €10,000 in 2026, the KIA is 28% × €10,000 = €2,800. The KIA is a deduction from profit, so the cash benefit depends on the income tax rate that applies to the business profit.

Which investments count for KIA in 2026, and which ones are excluded?

KIA applies to investments in business assets (bedrijfsmiddelen) used in the business, but not every purchase counts. You do not get KIA for assets below €450, for residential property and land, for goodwill and financial assets (securities and receivables), and for many passenger cars that are not for professional transport. KIA is also excluded for assets intended for at least 70% rental or for use abroad, and for several related-party transactions.

Many common freelancer purchases can be business assets, such as computers, specialist equipment, tools, and office furniture, as long as each asset is €450 or more and is not excluded. For KIA, the asset does not have to be new; second-hand assets can qualify if they meet the conditions for investment allowance.

For the investment amount, VAT (BTW) treatment matters. If the business can reclaim VAT on the purchase, the KIA base is the amount excluding VAT. If VAT cannot be reclaimed (for example, because the business only supplies VAT-exempt services), the KIA base is the amount including VAT. See the [VAT return guide](/knowledge-hub/vat-returns-netherlands-expat-freelancer-guide) for the basics.

• Count each qualifying business asset at the purchase amount (excluding VAT if VAT is deductible; including VAT if it is not).
• Exclude assets with an investment amount below €450.
• Exclude residential houses and land (including the ground under buildings).
• Exclude passenger cars not intended for professional transport.
• Exclude business assets intended for at least 70% rental or for use abroad.
• Exclude private-to-business transfers and certain purchases from close relatives or household members (unless an exemption applies).

When is an investment counted for KIA: contract date, payment date, or delivery date?

For KIA, “investing” means entering into a legal obligation to buy or improve a business asset. Examples include accepting a valid offer or signing a purchase agreement. KIA is reported in the return for the investment year, but if the asset is not yet in use, the claim for that year can be limited to what was paid until the year the asset is put into use.

This is why “before 31 December” usually means “sign the agreement or accept the offer by 31 December” if the goal is to have the investment fall in that calendar year. Delivery and the final payment can happen later, but the year-of-investment rules and the year-of-use rules determine how much KIA is claimable in each year.

Large assets that are not used quickly can also trigger the disinvestment rules. If a business asset is not put into use within 3 years after the start of the calendar year of the investment, the situation can be treated as a (fictitious) disposal for investment allowance purposes.

How do you claim KIA in the Dutch income tax return for 2026 investments?

KIA is claimed in the annual tax return for the year of investment. As an income tax entrepreneur, the return is filed digitally (via Mijn Belastingdienst, tax software, or a tax intermediary). The submission deadline is the date in the tax invitation letter, and it is often 1 May. If more time is needed, the Belastingdienst allows an extension request before the deadline; a common extension is 4 months.

Before filing, add up the total qualifying investments for the calendar year and apply the 2026 KIA table to calculate the deduction. The KIA is not the same as depreciation: depreciation spreads the cost over multiple years, while KIA is an extra deduction linked to the investment amount in the year(s) it is claimable.

To avoid mistakes, keep the calculation and evidence in one place. The [deductible expenses guide](/knowledge-hub/deductible-expenses-freelancers-netherlands) can help when deciding whether a purchase is a business cost, but KIA has separate eligibility rules (for example the €450 minimum per asset and the exclusion list). Keep the calculation, contract date, and invoice in the same file.

• Step 1: List each business asset bought or made in the year, and record the date you entered into the obligation (offer acceptance/contract).
• Step 2: Exclude assets below €450 and any excluded categories (for example land or many passenger cars).
• Step 3: Determine the KIA base per asset (excluding VAT if VAT is deductible; including VAT if it is not).
• Step 4: Sum the qualifying investment amounts for the year and compute the KIA using the 2026 table.
• Step 5: Enter the KIA amount in the investment allowance section of the annual return for that year.
• Step 6: Keep contracts, invoices, and proof of payment, and track whether the asset is disposed of within 5 years.

When do you have to repay KIA (desinvesteringsbijtelling), and what are the 2026 thresholds?

If a business disposes of assets for which investment allowance was claimed, part of the earlier deduction can be repaid through the desinvesteringsbijtelling (disinvestment addition). The addition applies if the asset is sold or gifted within 5 years after the start of the calendar year of the investment and the total disposal value is more than €2,900. The addition uses the same percentage as the earlier allowance and is capped at the earlier deduction.

Disinvestment rules are a practical reason to avoid buying assets solely to “hit the threshold” at year-end. If the business expects to sell the asset quickly, the KIA benefit may be partly or fully reversed. The disinvestment term is measured from the start of the investment year, not from the purchase date, so an investment made in December 2026 is still within the 5-year window until the end of 2031.

What happens if you file late or claim KIA incorrectly in 2026 (interest and penalties)?

Late or incorrect reporting can trigger tax interest and penalties. The Belastingdienst tax-interest percentage is 5% from 1 January 2026. Filing the income tax return after the formal notice (aanmaning) deadline can trigger a verzuimboete of €469 (up to €6,709 for repeat failures). Incorrect returns due to intent or gross negligence can trigger a vergrijpboete of 50% or 25% of the understated tax.

The Belastingdienst typically sends a reminder and then a formal notice (aanmaning). After the notice, the return must usually be submitted within 10 working days. Filing after that term can trigger the €469 verzuimboete, and repeated failures can increase the penalty up to €6,709. If the return results in tax to pay and the payment is late, the betaalverzuimboete is 5% of the unpaid amount with a minimum of €50 and a maximum of €6,709.
