BTW herziening in the Netherlands: when you must correct VAT

The BTW Bill That Arrives Two Years After the Purchase

For most purchases, the deduction is settled in the year of first use and never looked at again. Investment goods are the exception. Machines, vehicles, IT hardware, and buildings are tracked for years afterwards, because the right to deduct BTW rests on using the asset for taxed business activities, and what you intended on the day of purchase does not always match what happens later. If use drifts towards BTW-exempt activities, the original deduction turns out to have been too generous, and part of it goes back. If use drifts towards taxed activities, the original deduction was too cautious, and you can claim more.

The mechanism itself is old for machines and buildings, but it has just grown. From 1 January 2026, the same tracking applies to large services on real estate. Renovation and construction services costing 30,000 euros or more excluding BTW, first used on or after that date, are now followed for the year of first use plus four more years. Before 2026, the BTW on those services became final after the first year. A BV that refurbished its office this year is carrying a five-year obligation that the identical project would not have created in 2025.

Key takeaway: BTW herziening is not a penalty. It is a correction mechanism that makes the BTW system reflect how an asset was actually used over time, and it works in both directions. If taxed use falls, some BTW goes back to the Belastingdienst. If taxed use rises, you can reclaim additional BTW. The tracking runs for five years on moveable assets and on investment services, and for ten years on real estate.

Revision amounts end up in your ordinary BTW filing, so it helps to know how that cycle works first; when to file VAT Netherlands covers the return mechanics and deadlines.

Three Assets, Three Clocks

The revision period that applies to an asset decides how long the Belastingdienst follows the BTW deduction and how large each annual correction can be. Dutch law now has three categories, and each one runs its own clock.

All three clocks start from the same moment: the year the asset or completed service is first put into actual business use. The purchase date and the invoice date do not decide it. A machine delivered in November but not operational until January starts its clock in January. A renovation first used in December 2025 stays outside the new rules even if the final invoice arrives in 2026, because the date of first use is what counts.

The three clocks are independent of each other, and they can overlap on a single property. A BV that owns a building is already following the original acquisition BTW over ten years. If it renovates that building in 2026 for 200,000 euros, a second, five-year clock starts for the renovation. Each qualifying service gets its own period, so one property can carry several revision positions at once, and each needs its own record.

Not every purchase belongs in this system. The rules cover investment goods, meaning moveable assets you depreciate and real estate. Stock bought for resale is not an investment good, and its BTW deduction is final after the year of first use. That is one more reason the classification covered in inventory vs fixed assets Dutch bookkeeping matters well beyond the balance sheet.

What Triggers It and How to Calculate It

The calculation starts from one question: has the share of BTW-taxed use changed enough since the year of first use to matter? Every year within the revision period, you work out what share of the asset's use served taxed activities, and compare it with the share in the first year. A machine split between taxed production and exempt services needs a split of machine hours or output. A building usually needs a split of floor space or rental income between taxed and exempt use.

The tolerance works as a relative test, and this is where many explanations get it slightly wrong. The difference between the two percentages must be larger than 10% of the first-year percentage before any revision happens. When the asset started at 100% taxed use, that tolerance is 10 percentage points. When it started at 80%, the tolerance is 8 points. Within the tolerance you do nothing that year. Beyond it, you revise, and the revision covers the whole difference, not only the part above the tolerance.

The amount equals one fifth of the BTW charged to you on the purchase for moveable goods and investment services, or one tenth for buildings, multiplied by the full difference in percentage points. A drop in taxed use means extra BTW to pay. A rise means extra BTW to deduct.

The tolerance creates a cliff, so a small example helps. Take a machine on which 21,000 euros in BTW was charged, used 100% for taxed work in its first year. In a later year taxed use drops to 92%. The difference is 8 points, inside the 10-point tolerance, so nothing changes. In another year it drops to 85%. The difference is 15 points, beyond the tolerance, so the BV revises: one fifth of 21,000 euros times 15% is 630 euros to repay. The step from 8 points to 15 points did not add a few euros; it switched the obligation on.

Now a full run through a five-year period. A BV buys a machine in 2024 for 100,000 euros plus 21,000 euros BTW, with taxed use of 80% in the first year. The revision years run from 2025 to 2028. The tolerance is 8 points, 10% of 80.

In 2025, taxed use is 75%, a difference of 5 points, inside the tolerance, so no revision. In 2026, taxed use falls to 55%, a difference of 25 points, so the BV repays one fifth of 21,000 euros times 25%, which is 1,050 euros. In 2027, taxed use recovers to 85%, a difference of 5 points in the other direction, inside the tolerance, so no revision. In 2028 nothing changes and the period ends.

A sale also triggers revision. Selling an investment good within the period brings forward the revision for all remaining years in one go. Suppose a BV renovated its office for 200,000 euros plus 42,000 euros BTW, with first use in 2026 and 100% taxed use, and sells the building on 1 January 2029 in a BTW-exempt sale. Two years of the period remain, 2029 and 2030. When the sale is exempt, the calculation assumes fully exempt use for those years, so the BV repays two fifths of 42,000 euros, which is 16,800 euros. The same logic applies to other events that end taxed use, such as taking an asset out of the business.

Watch out: There is no separate return for revisions. The extra BTW you owe goes in rubriek 1a, and extra BTW you can reclaim goes in rubriek 5b, in your last BTW return of the year. For a quarterly filer, that is the Q4 return, filed in January. Because no invoice or payment prompts it, a revision is easy to skip, and an unreported revision is the kind of gap that surfaces in a boekenonderzoek.

A revision is checked against the same records an inspector looks at in any BTW audit, so documentation counts; surviving a boekenonderzoek covers what inspectors examine and how to prepare.

When Herziening Works in Your Favour

Most explanations present herziening only as money you hand back. That is half the picture. The mechanism is symmetrical, and when taxed use rises within the revision period, it lets you claim BTW you did not deduct at the start. The route is the same one: rubriek 5b of the last return of the year.

Picture a BV that buys a building in 2024 for 500,000 euros plus 105,000 euros BTW. At the start, only 30% of the building is let to a commercial tenant in a BTW-taxed way, and 70% is used for BTW-exempt medical services. The BV deducts 30% of the BTW, which is 31,500 euros. In 2026, the tenant expands and 60% of the building now serves taxed use.

The first-year percentage was 30%, so the tolerance is just 3 points. The shift is 30 points, far beyond it. The BV may deduct an additional one tenth of 105,000 euros times 30%, which is 3,150 euros, in its last return for 2026. If taxed use stays at 60%, the same extra deduction is available each year until the ten-year period ends in 2033.

This matters most for owners of mixed-use assets whose taxed activity grows. A care provider that adds commercial services, a school that develops taxed activities, or a property owner that moves part of a building from exempt to taxed use can all land here. Buildings are the most common case, and they usually involve the option for taxed rental, which comes with conditions of its own, so check them before counting on the extra deduction. In practice, many bookkeepers watch for repayments and not for recoveries. A routine yearly check of the use split on every tracked asset is how you catch both. The wider BTW cost picture for a Dutch entrepreneur is covered in how much tax you pay.

The 2026 Change: What Property-Owning Businesses Must Do Now

Since 1 January 2026, investment services on real estate carry a five-year revision period. For a BV that owns or rents business premises, renovation and construction work first used this year now brings a BTW tracking obligation that equivalent work did not carry in 2025.

The rule reaches any business that, in 2026 or later, has services performed on a building or land with a fee of 30,000 euros or more excluding BTW per service, provided the service is first used on or after 1 January 2026. A project begun in 2025 but first used in 2026 falls inside the rules. A project completed and put into use before 2026 does not.

The Belastingdienst's own description of an investment service is broader than many summaries suggest. It covers services that renew, enlarge, repair, replace, or maintain a building or land, demolition that belongs to a renovation, and materials and installations that become part of the building, such as pipes, heating systems, or machines fixed into the property. Its examples include painting window frames and doors, asbestos or soil remediation, fitting kitchens or bathrooms, insulation, and façade or roof renovation. That corrects a common assumption: maintenance is not excluded as a category. A 45,000-euro painting contract can be an investment service. A 12,000-euro one is not, but the reason is the threshold, not the type of work.

The threshold applies per service. A painter charging 25,000 euros and an electrician charging 10,000 euros are two separate services, both below 30,000 euros, and neither is caught. The sources I reviewed describe the threshold per service or assignment, not per invoice, so cutting one assignment into several smaller invoices should not be assumed to keep it below the line. Where a single assignment with one contractor exceeds the threshold, treat it as in scope.

For a BV with a 2026 project, a short routine keeps the obligation manageable. List every 2026 service over 30,000 euros excluding BTW and record the BTW charged on each. Note the planned taxed and exempt split in the year of first use, since that percentage is the benchmark for the next four years. Add each service to the fixed-asset records with its own five-year window, 2026 to 2030 for a service first used in 2026. Then, at the end of each year, compare the actual use split with the benchmark and calculate a revision if it moves beyond the tolerance. If a revision becomes likely, it needs reflecting in the books and the annual accounts, and annual accounts Netherlands covers how that reporting fits together. Keep in mind too that a revision is a different thing from correcting an invoice or a filed return, which creditfactuur Netherlands explains.

FAQs

What is BTW herziening?

BTW herziening, VAT revision, is the yearly check of whether an investment asset is still used for taxed and exempt activities in the same proportion as in its first year. If the proportion shifts beyond the tolerance, you repay part of the BTW you deducted or reclaim extra, depending on the direction of the shift.

How long is the revision period for a machine or vehicle?

Five years: the year of first use plus the four years that follow. It applies to moveable goods on which you depreciate for income tax or VPB, or could depreciate if those taxes applied to you. Stock held for resale is not covered.

How long is the revision period for a business building?

Ten years: the year of first use plus the nine years that follow. The deduction is checked against actual use in each of those years, and each year's correction is at most one tenth of the BTW charged on the purchase.

What is the new 2026 BTW revision rule for renovation services?

Since 1 January 2026, investment services on real estate are tracked for five years: the year of first use plus four. It applies to services first used on or after that date. The BTW deduction on such a service is no longer final after the first year.

What is the 30,000 euro threshold for the 2026 rule?

Only services with a fee of 30,000 euros or more excluding BTW per service fall under the new revision period. Smaller services are not tracked, and each qualifying service gets its own five-year period, so one building can have several revision periods running at once.

What triggers a BTW revision in a specific year?

A change in the share of taxed use beyond the tolerance, compared with the first year of use. Selling the asset within the revision period also triggers a revision for all remaining years, and so does taking the asset out of the business.

What is the 10% tolerance margin?

No revision applies in a year when the difference between that year's taxed-use percentage and the first-year percentage is no more than 10% of the first-year percentage. At a 100% start that is 10 points; at an 80% start it is 8 points. Beyond it, the full difference is revised.

How do I calculate the annual revision amount?

Take one fifth of the BTW charged on the purchase for moveable goods and investment services, or one tenth for buildings, and multiply it by the difference in percentage points between the first year and the year under review. For example, one fifth of 21,000 euros times a 25% shift is 1,050 euros.

Can BTW herziening result in a refund rather than a repayment?

Yes. If taxed use rises beyond the tolerance, you can deduct additional BTW. The extra amount goes in rubriek 5b of your last BTW return of the year, which makes the mechanism worth monitoring as a recovery opportunity, not only a liability.

Where do I report BTW herziening, in the quarterly or the annual return?

In your last BTW return of the year, there is no separate annual return for it. Extra BTW payable goes in rubriek 1a, and extra BTW you can reclaim goes in rubriek 5b. For a quarterly filer, that means the return for the fourth quarter.
