A Luxembourg SPV can complete a transaction in a single week and then remain in the structure for years. Its compliance cycle does not become dormant with the deal activity. Interest accrues, board decisions are taken, accounts are closed, tax returns are filed and beneficial ownership records remain current.

The calendar is most effective when accounting, tax and governance are treated as one workflow. Separate providers can perform the individual tasks, but the evidence has to reconcile across the SPV service perimeter, the company’s bank accounts and the sponsor’s reporting chain.

The first month after incorporation or closing

The compliance file should be built while the transaction documents are still current. The incorporation deed, shareholder register, RBE analysis, financing agreements, acquisition documents, bank evidence and signing authorities form the opening package.

The opening balance sheet then records capital, share premium, shareholder loans, transaction costs and the acquired asset. The classification of those amounts should not be postponed to year-end. A cost booked incorrectly at closing can affect the carrying value, interest computation and tax return for several years.

The registered office and domiciliation framework also need to match the operating model. Mail handling, corporate records, board logistics and local contact points are part of the recurring file, not just incorporation formalities.

The monthly and quarterly accounting cycle

Even a simple HoldCo benefits from a regular close. Bank movements, invoices, interest, foreign exchange, capital calls and distributions should be booked in the period to which they relate. A quarterly cycle is often sufficient for a low-volume vehicle, while acquisition platforms with active financing or service flows require monthly work.

The core controls are stable:

Area	Recurring control
Bank	reconciliation and explanation of all movements
Debt	principal, accrued interest, repayments and covenant data
Investments	acquisition cost, impairments and disposal evidence
Expenses	allocation to the correct entity and period
Governance	board approval for material transactions
Tax	VAT, withholding and direct-tax positions where relevant

Management fees or other intragroup charges must be supported by actual services and an arm’s-length rationale. The same evidence supports bookkeeping and transfer pricing.

Board and shareholder governance

Board records should follow the transaction rather than reconstruct it later. Financing amendments, acquisitions, disposals, dividends and material service arrangements generally require a documented decision at the appropriate entity level.

The minutes should show that the directors received the relevant information and exercised their own judgment. A Luxembourg board that only records decisions already implemented elsewhere weakens the substance file. Meeting logistics, attendance and signing should therefore align with the company’s stated central administration.

The annual shareholder decision approves the accounts, allocates the result and deals with discharge and appointments. Dividend decisions must remain consistent with distributable reserves and the Luxembourg withholding-tax framework.

Annual accounts and RCS filing

Luxembourg capital companies generally approve their annual accounts and the appropriation of profit within six months after the financial year-end. The filing follows within one month after approval, no later than seven months after year-end.¹

The process starts with a clean trial balance, not with the filing portal. Accrued interest, transaction costs, foreign exchange, impairment indicators and intercompany balances need support. The annual accounts are then prepared under the applicable Lux GAAP framework and validated through eCDF before the RCS filing where required.

The existing guide to annual accounts filing covers the filing mechanics and late-fee exposure in detail.

Corporate tax and net wealth tax

The standard deadline for corporate income tax and municipal business tax returns is 31 December of the year following the tax year. The same deadline applies to the connected net wealth tax return under the current framework.²

The return should reconcile with the approved accounts while separately documenting tax adjustments. Participation exemption, interest limitation, transfer pricing, non-deductible expenses and net wealth tax require their own workpapers. A low accounting profit does not imply a low taxable base.

Tax advances and assessments need to be tracked between filings. The SPV may receive quarterly statements or requests that do not coincide with the annual accounts calendar. A tax account reconciliation prevents old advances or refunds from disappearing inside a general receivable.

VAT and withholding taxes

A passive holding company is not automatically a VAT taxable person. The position changes when the SPV supplies management or other services for consideration. The Luxembourg VAT guide provides the broader framework.

Interest and dividend flows may also create withholding or reporting obligations. The contract, recipient, treaty position and domestic exemption must be reviewed before payment rather than after the bank transfer.

RBE, registers and ongoing changes

The beneficial ownership analysis should be revisited whenever the ownership chain, control rights or senior decision-making changes. An annual review is a useful control but does not replace an event-driven update.

The shareholder register, directors, signing powers and registered office should match the RCS and the company’s corporate file. KYC records held by the bank, domiciliary and service providers should be refreshed from the same source.

A practical year-end sequence

The cleanest sequence is to freeze the ledger, resolve intercompany differences, prepare tax workpapers, document valuations and impairments, approve the accounts, complete the RCS filing and then finalise the tax return. The order keeps the accounting, governance and tax narratives aligned.

For private equity structures, the annual close is also a portfolio reporting exercise. Fund-level reporting, consolidation packages and lender information may use the SPV numbers before the statutory deadline. A controlled calendar therefore improves both compliance and investor reporting.
