A March 2026 Tax Administration ruling confirms that BV losses incurred in 2024 before the January 1, 2025, WFKR transition don’t block rollover relief.
Those losses enter the standard carry-forward regime, subject to quantitative restrictions.
This timing gap creates practical challenges for restructuring and has real consequences for business planning and execution.
Core Facts
- BV losses incurred before January 1, 2025, don’t create an entitlement to loss carry-forward under Article 20 of the Corporate Income Tax Act 1969
- These losses don’t trigger the loss-absence condition under Article X of the WFKR.
- Losses remain deductible but enter the standard carry-forward regime with a €1 million threshold and 50% cap on excess profits.
- The restriction applies because Article 20 operates on a full financial year basis, and no entitlement exists until the year closes.
- This affects cash flow planning, fiscal unity structuring, and loss utilization in subsequent years.
The Dutch Tax and Customs Administration issued a technical clarification in March 2026 addressing a specific but consequential scenario.
If a BV acquires a limited partnership share in an open CV in 2024, incurs costs before year-end, and seeks to apply WFKR rollover relief as of January 1, 2025, the result is clear procedurally but complex operationally.
The answer is procedurally clean but operationally uncomfortable.
A negative profit realized before January 1, 2025, doesn’t create an entitlement to loss carry-forward under Article 20 of the Corporate Income Tax Act 1969.
Those losses don’t trigger the loss-absence condition under Article X of the WFKR. But those losses sit in a timing gap many founders didn’t anticipate when restructuring under deadline pressure in late 2024.
This is about how Dutch corporate tax law defines a loss, when it becomes deductible, and what the timing implications are for businesses restructuring open CV structures under the WFKR transition provisions.
What Changed on January 1, 2025?
As of January 1, 2025, the open commanditaire vennootschap ceased to exist as an independently taxable entity in the Netherlands.
The distinction between open and closed CV structures was eliminated through the Wet fiscaal kwalificatiebeleid rechtsvormen (WFKR). All CVs became fiscally transparent by default unless they qualified as a fund for joint account (FGR).
The change was designed to reduce hybrid mismatches in cross-border tax situations. The change created instant operational pressure for businesses using the open CV structure, particularly in real estate investment and regulated fund arrangements.
The hard deadline was December 31, 2024. Businesses had until this date to complete any restructuring under transitional rollover relief provisions. The Dutch government explicitly stated there would be no amendment to the legislation. This left a narrow window for execution. Many owner-managed businesses worked to comply.
Article IX of the WFKR introduced a deemed transfer fiction. Immediately before January 1, 2025, the open CV was treated as having transferred all assets to the participants, including any acquiring BV.
To avoid recognizing taxable profit from the fictitious transfer, businesses relied on Article X, the rollover relief provision. The relief came with conditions.
Bottom line: The WFKR eliminated the open CV structure and created a hard December 31, 2024, deadline for restructuring. Businesses were required to navigate deemed transfers and rollover relief conditions under time pressure.
How Does the Loss Absence Condition Work?
Article X, paragraph 1 of the WFKR states rollover relief applies automatically, without a formal request, provided certain conditions are met.
One condition: neither the open CV nor the limited partners has an entitlement to loss carry-forward under Article 20 of the Corporate Income Tax Act 1969.
This is not new. The same loss-absence condition applies in the regular Dutch reorganization facilities under Articles 14, 14a, 14b, and 14ba of the Corporate Income Tax Act. The rationale is anti-abuse: to prevent tax claims on transferred assets from being eroded through loss compensation by the receiving party.
The question in practice: does a BV incurring costs in 2024, before the deemed transfer date of January 1, 2025, have an entitlement to loss carry-forward blocking automatic rollover relief?
What to remember: Rollover relief applies automatically if no loss carry-forward entitlement exists. The anti-abuse rule intends to protect tax claims on transferred assets from being eroded by the receiving party’s losses.
Why Timing Determines Loss of Entitlement
The Tax Administration says no.
Here is why:
Loss carry-forward under Article 20 of the Corporate Income Tax Act operates on a full financial year basis. A loss is recognized only when the calculation of taxable profit for an entire financial year results in a negative amount. The loss becomes deductible, and the entitlement arises only after the financial year ends, when the loss is formally determined by the Inspector in a decision that is appealable.
Article X of the WFKR tests the situation immediately before January 1, 2025. At that moment, the financial year 2024 had not yet closed. No loss has been determined. No entitlement to carry-forward exists.
The Tax Administration confirms this: “Because the test in Art. X of the WFKR relates to the situation immediately prior to 1 January 2025; no entitlement to forward loss set-off for 2024 exists at this time.”
This applies even if:
- The BV’s first financial year runs only until December 31, 2024
- The BV is an existing company without prior loss years.
- The negative profit consists of accumulated negative hidden reserves rather than realized costs.
The statutory reference to Article 20 is decisive. The anti-abuse purpose of the loss-absence condition does not override the plain language of the law.
The core principle: Loss entitlement arises only after the financial year closes and the Inspector formally determines the loss. Before January 1, 2025, there is no entitlement for 2024 losses.
What Are the Practical Consequences?
The key takeaway: The ruling creates clarity on procedures but leaves businesses exposed to practical setbacks resulting from timing gaps.
A BV acquiring a CV share in 2024 and incurring costs before year-end doesn’t trigger the loss absence condition. Rollover relief applies automatically under Article X, paragraph 1 of the WFKR without filing a formal request.
But those 2024 losses aren’t lost. They remain deductible, subject to the standard Dutch loss carry-forward rules introduced in 2022.
Under those rules, losses carry forward indefinitely, but with quantitative restrictions. Losses offset fully only up to €1 million of taxable profit per year. For profits exceeding €1 million, only 50% of the excess is offset against losses.
For small businesses with losses from a restructuring year, the 50% cap on profits above €1 million directly impacts cash flow and future tax planning.
How Fiscal Unity Complicates Loss Utilization
The complexity deepens if the BV later joins a fiscal unity, a consolidated tax group.
When companies with pre-fiscal unity losses join a fiscal unity, those losses offset only the taxable profits generated by the specific company that incurred them. They don’t offset the wider group’s profits.
The €1 million threshold applies once per fiscal unity, not per company. This creates allocation challenges and calls for careful record-keeping to substantiate loss positions when companies later exit the unit.
For businesses restructuring under time pressure in late 2024, the timing gap between incurring losses and being able to utilize them heightened the complexity. This disconnect affected loss modeling and planning, creating unforeseen obstacles.
Main implication: 2024 losses remain deductible but enter a restricted carry-forward regime with a €1 million threshold and 50% cap on excess profits. In a fiscal union, losses remain company-specific.
What Was the Administrative Burden?
The December 31, 2024, restructuring deadline created procedural friction that many small operators underestimated.
The Dutch Tax Administration requires up to two months to respond to advance ruling requests (vooroverleg). For businesses needing certainty on loss treatment or rollover relief eligibility before the year-end deadline, formal consultation had to begin by October 2024 at the latest.
Many businesses missed that window. The result: restructuring during uncertainty, with loss treatment clarified only after the fact through rulings like the one issued in March 2026.
How Do Ownership Changes Affect Loss Carry-Forward?
Dutch law contains anti-abuse provisions that prevent loss carry-forward when ultimate ownership in a company changes substantially, 30% or more, compared to the year of the oldest loss.
This restriction doesn’t apply if the company is an active trading company with no substantial decrease in activity and no plans for substantial expansion. But for businesses restructuring through BV acquisitions of CV shares, ownership continuity must be meticulously managed to preserve loss positions.
Administrative reality: The December 31, 2024, deadline meant businesses needed to start advance ruling requests by October 2024. Many missed this window and restructured during uncertainty. Ownership changes of 30% or more threaten loss carry-forward.
What Should Founders Understand?
The March 2026 clarification doesn’t create new exposure. It confirms how the existing statutory framework functions when WFKR timing interacts with loss carry-forward rules.
But the ruling highlights a structural blind spot: the difference between avoiding a procedural barrier and preserving economic value.
A BV incurring costs in 2024 before the WFKR transition applies rollover relief automatically. But those losses enter the standard carry-forward regime, subject to quantitative restrictions that are not always anticipated during restructuring.
For businesses with material 2024 losses:
- Loss utilization is subject to the €1 million threshold and 50% cap on excess profits.
- Losses remain company-specific if the BV later joins a fiscal unity.
- Ownership continuity must be maintained to preserve loss positions.
- Record-keeping must be sufficient to substantiate losses when they are eventually deducted.
The operational consequence isn’t immediate. But the restriction surfaces in tax planning, cash flow modeling, and fiscal unity structuring in the years following the restructuring.
Structural reality: Avoiding the procedural barrier (loss-absence condition) doesn’t preserve the full economic value. Losses remain deductible, but with quantitative restrictions affecting cash flow and tax planning.
What Steps Should You Take?
If you restructured an open CV through a BV acquisition in 2024 and incurred losses before year-end:
Document the loss position clearly. Ensure 2024 costs are correctly recorded, and the loss determination is documented by your 2024 or extended first-year tax return. Loss carry-forward requires a formal determination by the Inspector.
Model the utilization timeline. If you expect taxable profits in future years, calculate how the €1 million threshold and 50% cap affect the utilization of losses. This affects cash flow, not just tax liability.
Review fiscal unity implications. If the BV is part of, or will join, a fiscal unity, confirm how pre-unity losses will be allocated and whether the €1 million threshold applies at the group or company level.
Check ownership continuity. If ownership in the BV has changed or will change, confirm the 30% anti-abuse threshold isn’t triggered. Loss carry-forward gets blocked if ownership shifts materially compared to the year of the oldest loss.
Retain restructuring documentation. The WFKR transition involved deemed transfers, rollover relief, and timing elections. Keep records that confirm the tax treatment applied, particularly if the loss position is later challenged or audited.
Action required: Document losses clearly, model utilization timelines, review fiscal unity implications, check ownership continuity, and retain all restructuring records.
This is structural. The WFKR transition created a timing gap that affects how losses are recognized, when they become deductible, and how they interact with other Dutch tax provisions.
The March 2026 clarification confirms the mechanism. The operational consequence depends on how you model and manage the loss position in the years that follow.
If you restructured under time pressure in late 2024, confirm now that your loss treatment is consistent with the statutory framework and that your tax planning reflects the quantitative restrictions introduced in 2022.
Structure is not bureaucracy. It is the price of staying in control.
Frequently Asked Questions
Do BV losses from the 2024 block WFKR rollover relief?
No. BV losses incurred before January 1, 2025, don’t create an entitlement to loss carry-forward under Article 20 of the Corporate Income Tax Act 1969. Therefore, they don’t trigger the loss-absence condition under Article X of the WFKR. Rollover relief applies automatically.
Where do 2024 BV losses go if they don’t block rollover relief?
Those losses remain deductible. They enter the standard Dutch loss carry-forward regime introduced in 2022, subject to a €1 million threshold and 50% cap on excess profits.
Why don’t 2024 losses create an entitlement before January 1, 2025?
Article 20 of the Corporate Income Tax Act operates on a full financial year basis. Loss entitlement arises only after the financial year ends and the Inspector formally determines the loss. Before January 1, 2025, the financial year 2024 has not closed. No entitlement exists at that point.
What happens if the BV joins a fiscal unity later?
Pre-fiscal unity losses offset only taxable profits generated by the specific company incurring them. They don’t offset the wider group’s profits. The €1 million threshold applies once per fiscal unity, not per company.
How do ownership changes affect loss carry-forward?
Dutch anti-abuse rules prevent loss carry-forward when ultimate ownership in a company changes substantially, 30% or more, compared to the year of the oldest loss. This applies unless the company is an active trading company with no substantial decrease in activity.
What should businesses that restructured in late 2024 do now?
Document the loss position clearly. Model the utilization timeline. Review fiscal unity implications. Check ownership continuity. Retain restructuring documentation. Confirm your loss treatment complies with the statutory framework.
Does the €1 million threshold apply per company or per fiscal unity?
The €1 million threshold applies once per fiscal unity, not per company. This creates allocation challenges when multiple companies with losses join a fiscal unity.
When did the WFKR deadline fall?
December 31, 2024. Businesses had until that date to complete restructuring under transitional rollover relief provisions. The Dutch government stated there would be no amendment to the legislation.
Key Takeaways
