KIA: an extra deduction when you invest in your business

When you invest in your business — a new laptop, professional camera, workshop equipment, or software license — you want that expense to reduce your tax bill. The Dutch tax system lets you do this twice: first through depreciation, and second through the KIA (kleinschaligheidsinvesteringsaftrek), a hidden tax break that many freelancers miss entirely.

What is the KIA?#

The KIA is an extra deduction on top of depreciation. In plain terms: if you invest more than a certain threshold in business assets in a single year, you can claim an additional deduction that cuts your taxable profit further.

It's not a refund — it's a deduction, which means it reduces your profit before tax is calculated. On a 37% marginal tax rate, an extra €1,000 deduction saves you about €370 in tax.

Think of it as the tax authority rewarding you for investing back into your business rather than pocketing all the profit.

The KIA threshold#

The system triggers when you invest more than roughly €2,900 in qualifying business assets in a calendar year. The exact threshold changes annually, so check belastingdienst.nl for the current figure.

Below that threshold: you'll use standard depreciation (afschrijving) instead, spreading the cost over the asset's useful life.

Above it: you unlock the KIA deduction on top of depreciation, giving you a faster tax recovery.

How much can you deduct?#

The deduction percentage varies depending on which "band" of investment you fall into. The rough structure is:

• The first band (from the threshold up to a certain amount) qualifies for a higher percentage (up to ~28%)
• Higher bands may have lower percentages

The exact percentages and band boundaries change yearly — the tax authority adjusts them. This is why you must link to the official source rather than relying on a fixed number here.

The bottom line: if you invest €5,000 in a year and hit the threshold, a significant slice of that investment gets an extra deduction beyond normal depreciation.

• Check if your total business investments for the year exceed ~€2,900
• Identify which assets qualify (see below)
• Look up the current KIA percentages and bands on belastingdienst.nl
• Calculate the extra deduction
• Claim it when filing your income tax return

What qualifies for the KIA?#

Most business assets qualify: laptops, vehicles, machinery, office equipment, software, tools, furniture. The asset must be:

• New (sometimes second-hand within limits)
• Used for your business
• Not a land or building (though some building improvements may qualify separately)

Common qualifying investments:

• Computers and electronics
• Business vehicles
• Professional equipment (cameras, printing machines, workshop tools)
• Software and SaaS subscriptions (annual cost can count)
• Furniture and fixtures in a dedicated business space

What doesn't qualify:

• Land or buildings
• Vehicles primarily for private use (if you use a car 50/50 business/private, only the business share counts)
• Stocks, bonds, financial assets
• Acquired second-hand from related parties

KIA vs. depreciation: the difference#

Here's the key distinction, because it trips up a lot of freelancers.

Depreciation (afschrijving) spreads the cost over the asset's useful life — typically 5 years for most equipment (20% per year). It's mandatory and automatic for assets over €450.

KIA is an extra deduction in the year you buy, on top of depreciation. It's accelerated tax relief for investment.

Example:

• You buy a €5,000 laptop in 2025.
• Depreciation: you deduct €1,000/year for 5 years (5-year lifespan assumed).
• KIA: in 2025, if the laptop pushes you over the ~€2,900 threshold, you get an additional deduction (percentage depends on the band, roughly 20–28%).
• Result: in year 1, you deduct significantly more than just the depreciation alone. In years 2–5, you deduct the normal depreciation amount.

This makes KIA especially valuable if you have a lumpy investment year — buy a lot of equipment in one year and get a bigger tax break upfront.

A worked example#

Year: 2025. Scenario: You're a design freelancer. You buy a new iMac (€3,500), software licenses (€800/year), and a refurbished desk (€400). Total: €4,700.

1. Above threshold? €4,700 is above the ~€2,900 threshold, so the KIA applies.
2. Depreciation: The iMac and desk are depreciated over 5 years (€820/year combined, estimated). The software is fully expensed in the year of purchase (€800).
3. KIA deduction: The amount above the threshold (€4,700 − €2,900 = €1,800) qualifies for the KIA band deduction. If the applicable band is 20%, you get an extra €360 deduction in 2025.
4. Tax result: Rather than deducting €1,820 in year 1 (depreciation + software), you deduct €2,180 (depreciation + software + KIA). On a 37% tax rate, that's €133 in tax saved in year 1 alone.

Note: these percentages are illustrative. Check the current rates before claiming.

When does KIA make a real difference?#

KIA is most valuable if:

• You have a lumpy investment schedule (spending €8,000 one year, €500 the next)
• You're in a higher tax bracket (the deduction's tax value is higher)
• You invest in a mix of assets that have long depreciation schedules (the KIA gives you upfront relief)

It's less valuable if:

• You invest very little each year (below the threshold)
• You're in a low tax bracket (the deduction saves you less)
• Most of your investments are low-cost items that fall under the €450 expensing rule (you already get immediate deduction)

Claiming the KIA on your return#

When you file your annual income tax return, the KIA goes on the form as part of your calculated deductions. It's not a separate tax form — it flows into your total aftrekposten (deductible costs) before calculating taxable profit.

If you use tax software or a boekhouder, they will typically calculate it automatically if you've recorded your investments. But it's worth spotting yourself so you can double-check:

1. Make sure all qualifying investments are recorded as assets (not just expenses)
2. Verify the total for the year
3. Cross-check against the current KIA thresholds and percentages
4. Confirm it's included in your declared deductions

Frequently asked questions#

The KIA is one of those tax breaks that rewards business investment — but it only works if you're aware of it and track your assets properly. Bundling equipment purchases into one year (if legitimate for your business) can unlock meaningful tax savings. Use ZZP Belasting to log your investments as you go, so you'll never miss calculating the KIA.
