The wire has cleared, the notary has closed the file, and the target continues to invoice its customers on Monday exactly as it did on Friday. That continuity is what makes the weeks after completion deceptive. Operationally very little changes; legally and fiscally, a great deal has. A company that was previously stand-alone is now a subsidiary within a group, with a parent that expects reporting, a lender that expects covenants, and a tax authority that will eventually ask who decided what, where, and on what commercial basis. The first ninety days are not about optimisation. They are about making the group’s own account of itself accurate before anyone else writes one.
The ownership chain and the right to sign
Start with the boring register work, because everything else is built on it. Shares in a BV transfer by notarial deed; the shareholders’ register must be updated to match, and the KVK filings must reflect the new statutory directors and the new ultimate beneficial owners. Access to the UBO register has been restricted since the Court of Justice ruling of November 2022, but the filing obligation itself has not softened. Where the acquired entity sits in a chain of holding vehicles, confirm that each link is documented and that the articles of every entity in the chain say what the transaction assumed they said, particularly on transfer restrictions, approval rights and the appointment and removal of directors.
Then map signing authority as it now stands, not as the organisation chart imagines it. Which directors bind the company alone and which only jointly; which powers of attorney survived completion and which should have been revoked; who holds the bank mandates; which employees can commit the company to supply contracts, leases or guarantees. A signature matrix that is agreed by the parent and filed with the corporate records is worth more than any amount of subsequent correspondence about whether a commitment was authorised.
The intragroup contracts that now exist
From the moment of completion, relationships exist between the target and the rest of the group whether or not anyone has written them down. Group management provides oversight. Treasury may sweep cash. Head office may hold trade marks, software or customer data that the subsidiary uses. Someone is seconded, someone guarantees a facility, someone provides IT and insurance cover. Each of these is a transaction between associated enterprises, and each needs a contract that describes what is actually being supplied, by whom, on what terms and against what consideration.
The common failure is not aggressive pricing; it is silence. A management fee invoiced monthly with no underlying agreement, no description of services and no evidence of benefit to the recipient is difficult to defend years later, even when the amount is modest and the commercial logic obvious. The same applies to interest-free intragroup balances that accumulate quietly and to guarantees given without any recognition of the benefit conferred. Document them while the facts are fresh and the people who negotiated the deal are still available.
Transfer pricing from the first invoice, not the first audit
Article 8b imposes the arm’s length principle and an accompanying documentation obligation without any threshold; size does not exempt a group from having to explain its intragroup pricing. Formal Master File and Local File requirements attach from consolidated revenue of 50 million, country-by-country reporting from 750 million, and the Pillar Two minimum of 15 per cent applies to groups above that same 750 million threshold. Below those levels the substantive obligation remains; only the prescribed format falls away.
What matters in the first quarter is deciding the components rather than negotiating a number: which costs enter the base, whether a mark-up is applied and to what, which allocation keys are used for shared services, how the recipient’s benefit is evidenced, and how often the policy is reviewed. Set it once, apply it consistently from the first invoice, and record the reasoning at the time. Our note on the article 8b documentation obligation sets out how that file is normally assembled.
A transfer pricing policy written in month one is a policy. The same document written in year three, after the first information request, is an argument.
Acquisition financing and whether the interest actually deducts
Most acquisitions are funded with some combination of external debt, shareholder loans and equity, and the deductibility of the resulting interest is rarely a single question. The earnings stripping rule implementing ATAD caps net interest at a percentage of fiscal EBITDA above a minimum threshold, and both the percentage and the threshold have been adjusted since introduction, so the position must be tested against the parameters in force for the year concerned rather than remembered from a previous transaction. Separately, specific anti-abuse provisions address debt used to acquire participations, and hybrid mismatch rules can deny deductions where the corresponding receipt is not taxed as expected in the lender’s jurisdiction.
There is a structural point behind the technical one. The participation exemption exempts dividends and capital gains on qualifying participations, subject to a minimum holding and to the motive, subject-to-tax and asset tests; it is mandatory and symmetrical rather than elective, so exempt returns come with non-deductible losses. Debt serviced out of exempt income therefore produces interest expense against returns that sit outside the base, which is the pattern the limitation rules are designed to catch. Where interest or royalties flow to low-taxed or listed jurisdictions, the conditional withholding tax in force since 2021 is a further consideration, and it applies alongside, not instead of, the deduction rules. The interaction is set out further in our discussion of the ATAD interest limitation.
VAT, registration and the first returns
The VAT position of a new holding entity follows what it does rather than what it is called. A pure holding company that merely owns shares is generally not a taxable person and cannot recover input VAT; a holding that supplies management services for consideration ordinarily is, with corresponding recovery on costs attributable to those supplies. This distinction decides the treatment of a material part of the transaction costs, so it should be resolved deliberately rather than assumed on the first return. Where a VAT group is contemplated, the financial, economic and organisational links must all be present and demonstrable.
Alongside this sit the practical registrations: VAT numbers where new supplies are made, payroll registration for any seconded or newly employed staff, listings for cross-border services, and reverse charge treatment applied consistently in both directions. Our overview of VAT for international holding companies covers the recovery analysis in more detail. If the target holds Dutch immovable property, check whether the share acquisition itself fell within the scope of real estate transfer tax, which can extend to shares in a property-rich company; the general rate for property differs from the rate applicable to a dwelling acquired as the buyer’s own residence.
Governance and the composition of the board
Since the ruling policy of July 2019, real economic nexus has been a precondition for advance certainty, and no ruling is available where the decisive motive is tax saving or where listed jurisdictions are involved. The wider point is that governance quality is now evidential. Who sits on the board, where they are resident, where meetings are held, what is actually decided there and whether the minutes record deliberation rather than ratification are all facts that will be tested against the group’s own description of itself.
Practically, this means agreeing a reserved matters list between parent and subsidiary, ensuring the board has the information it needs to make the decisions reserved to it, calendaring meetings for the year rather than convening them reactively, and resolving conflicts of interest before they arise on a live transaction. Where a works council or comparable employee body exists, its consultation rights on post-completion reorganisations should be confirmed early, since they constrain sequencing.
The calendar, and what the first quarter should produce
Corporate income tax is charged at 25.8 per cent in the upper bracket with a reduced rate in the first bracket, and provisional assessments should be revisited once the post-completion forecast is credible rather than left at the target’s historic figures. Dividend withholding tax at the general rate of 15 per cent may be reduced by treaty or exempt within the EU, in each case subject to anti-abuse conditions that require examination before a distribution is declared, not afterwards. Add statutory accounts filing at the KVK, periodic VAT returns and listings, payroll deadlines, and any DAC6 reporting arising from the acquisition itself where the relevant hallmarks are present, the obligation falling on the intermediary or, failing that, on the taxpayer.
By the end of the period the group should be able to produce, without reconstruction, a complete corporate file and signature matrix, a signed set of intragroup agreements, a transfer pricing policy applied from the first invoice, a financing memorandum recording the deduction analysis, a documented VAT position, and a filing calendar with named owners. None of this is glamorous work. It is simply the difference between a group that can explain itself on request and one that has to reconstruct itself under time pressure.
