How Does the Month-End Close Work at a Payment Company Holding Customer Money?

Key takeaways

• At a firm holding customer money, the month-end close starts from the last daily reconciliation of the month, because customer funds must already be reconciled every day under rules such as CASS 15.8 in the UK and Circular CSSF 26/906 in Luxembourg.
• Five reconciliations must agree before the books close: processor to bank settlement, safeguarded or FBO accounts to customer liabilities, intercompany positions, fee revenue to amounts swept out of customer accounts, and the general ledger to all of these.
• Under IAS 21, foreign currency monetary items such as customer balances and intercompany loans are retranslated at the closing rate and the exchange differences go to profit or loss; intragroup balances still produce FX results on consolidation.
• The UK monthly safeguarding return is due within 15 business days of month end under SUP 16.14A.3R; the NMLS MSB Call Report is due 45 days after each quarter end; Luxembourg firms file a monthly third-party funds table with the CSSF.
• A ten working day close can file every one of these returns from the same reconciled figures, provided the regulatory figures are produced inside the close rather than after it.

What are the key facts about the month-end close at a payment company?

A payment company's close adds customer money, several regulators and several currencies to the ordinary close, and the figures must agree with returns filed from the same month end.

How is the close different when a business holds customer money?

The close cannot discover a problem with customer funds for the first time, because the rules already require those funds to be reconciled daily.

In the UK, CASS 15.8 requires an internal safeguarding reconciliation (the firm's own records of what it owes customers against what it holds for them) and an external reconciliation (the firm's records against the bank's or custodian's statements) as often as necessary and no less than once each reconciliation day (CASS 15.8.19R and 15.8.42R). A shortfall must be paid in by the end of the day the reconciliation is performed, and any excess withdrawn (CASS 15.8.50R). In Luxembourg, paragraph 203 of Circular CSSF 26/906, which applies from 30 June 2026, requires daily controls and reconciliations, with weekly allowed only on a documented, board-approved risk analysis. US state money transmitter regimes take a different route: the licensee must hold permissible investments (assets of the types state law allows) at least equal to its outstanding transmission obligations, which the MSB Call Report then tests quarter by quarter.

The practical result is that a payment company's month end is the last daily reconciliation of the month, plus the accounting work that sits on top of it: accruals, revaluation, revenue, consolidation and reporting. A close that treats customer funds as a month-end exercise is either repeating daily work or exposing that the daily work was not done. Both cost days.

The second difference is scale. A group holding customer money in several countries runs a separate position for each legal entity, in each currency, and none of them may be offset against another. Our guide to multi-entity reconciliation explains how those positions roll up to a group total without netting.

Which reconciliations must be complete before the books close?

Five reconciliations, each agreed per entity and per currency, must be complete and reviewed before the general ledger is locked.

An FBO account is a bank account held "for the benefit of" a fintech's customers, typically at a sponsor bank in the US; the fintech's own ledger is the only record of how that balance divides between customers. Our guide to FBO account reconciliation covers that control in detail. For intercompany balances, the rule that matters at month end is that both sides are agreed in the same currency before consolidation starts; intercompany reconciliation for payment groups sets out the matching and settlement approach.

How are foreign currency balances revalued at month end?

Every foreign currency monetary item is retranslated at the closing rate, and the difference is recognised in profit or loss for the month.

IAS 21 defines monetary items as units of currency held and assets and liabilities to be received or paid in a fixed or determinable number of units of currency (paragraph 8). For a payment company that covers almost everything on the customer side of the balance sheet: bank and safeguarding balances, customer e-money or stored-value liabilities, processor receivables and intercompany loans. Paragraph 23(a) requires these to be translated using the closing rate at the end of each reporting period, and paragraph 28 sends the exchange differences to profit or loss. Paragraph 45 adds that an intragroup monetary balance cannot be eliminated on consolidation without showing the results of currency movements, so an intercompany loan between entities with different functional currencies (the currency each entity keeps its books in) produces a real FX gain or loss in the group accounts.

Two disciplines keep revaluation clean. First, use one closing rate source and time for every entity, set in the close calendar. Second, keep the regulatory test separate from the accounting translation: the safeguarding position is tested in each currency the firm owes customers, before any translation. Paragraph 214 of Circular CSSF 26/906 recommends holding users' funds in the currency owed and requires extra FX protection where a firm does not. Our guide to multi-currency reconciliation covers the currency-by-currency matching that comes first.

How is fee revenue recognised and swept out of customer accounts?

Fees earned from customers are the firm's own money once earned, so they must be recognised as revenue and moved out of customer accounts, with the two amounts agreeing.

Where a firm deducts its fee from funds it holds for customers, the fee sits inside the safeguarded or FBO balance until it is moved. Left there, it shows as an excess in the customer funds reconciliation. CASS 15.8.50R requires an excess to be withdrawn, and paragraph 210 of Circular CSSF 26/906 states that funds held for users must not at any time be mixed with other funds, naming fees and commissions linked to payment and e-money services specifically.

For the close, this creates a three-way check: the fee calculated from transaction data, the revenue posted in the ledger, and the sweep payment from the customer account to the operating account. A sweep larger than recognised revenue suggests customer money has left protection; revenue larger than the sweep means the firm's money is still mixed with customers'. Both should be visible from the last daily reconciliation, and both should be cleared before the regulatory figures are taken.

What does a ten-day close calendar look like for a payment company?

A ten working day close front-loads the customer funds work, so that accounting and regulatory reporting draw on figures that are already agreed.

Working days differ by country, so the calendar should state which country's business days apply to each entity. The UK return's 15 business day window is counted on UK business days and leaves a margin after day 10; the NMLS deadline is counted in calendar days.

Which regulatory returns are filed from the same month-end figures?

At least three regimes take their figures directly from the payment company's month-end or quarter-end position, and each must agree with the close.

For October 2026, the UK return falls due by 20 November 2026 (15 UK business days after 31 October), and the third quarter MSB Call Report falls due on 14 November 2026 (45 days after 30 September). The SUP 16.14A rules apply SUP 16.3.11R and 16.3.13R on complete and timely reporting to safeguarding institutions. The NMLS filing schedule and the Section III instructions set what the US return asks for; line PI130, average daily transmission liability, is only available to a firm that has measured its liability every day of the quarter. The CSSF legal reporting page lists the Luxembourg tables.

Our guides to the monthly safeguarding return and the NMLS MSB Call Report go through each return line by line.

What does a month-end close look like in numbers?

A UK e-money entity holding US dollar customer funds shows how the safeguarding test, the fee sweep and the FX revaluation fit together.

Worked example, with illustrative figures. Nexus Payments has a UK e-money institution whose functional currency is sterling. At 31 October it owes customers USD 10,000,000 of e-money and holds USD 10,050,000 in its US dollar safeguarding account. It also has a USD 2,000,000 intercompany loan to its US money transmitter. The previous month-end rate was 1.3000 US dollars per pound; the closing rate is 1.2500.

Step 1, the safeguarding test, is done in dollars: USD 10,050,000 held against USD 10,000,000 owed gives an excess of USD 50,000. The fee calculation for the month shows USD 50,000 of fees deducted from customer balances and recognised as revenue, so the excess is explained. The USD 50,000 is swept to the operating account and the safeguarding account then holds exactly USD 10,000,000.

Step 2, the revaluation, is done in sterling. Each dollar balance is retranslated at 1.2500 instead of 1.3000.

The gain on the safeguarded cash and the loss on the customer liability almost cancel, because the funds are held in the currency owed. The net gain of GBP 63,077 arises from the firm's own dollar balances: about GBP 1,538 on the USD 50,000 of fees and GBP 61,538 on the intercompany loan, which make GBP 63,077 once rounding is applied. The US entity records its USD 2,000,000 payable in its own functional currency and has no FX difference, so on consolidation the loan eliminates but the GBP 61,538 gain stays in group profit or loss, as IAS 21 paragraph 45 requires.

Step 3, settlement: the processor reports USD 1,182,000 of net card settlement for 31 October that reaches the bank on 2 November. It is listed as a timing item with its expected date and cleared on working day 2, not raised as a break. The return for the UK entity then reports the USD 10,000,000 position that the reconciliation already proved.

What audit evidence should the close leave behind?

Every figure in the accounts and every figure in a return should trace back to a dated, reviewed reconciliation without anyone rebuilding it.

For each entity and currency, the evidence pack should hold the last daily customer funds reconciliation with preparer, reviewer and timestamps; the settlement reconciliation with its timing items and the dates they cleared; the signed intercompany matrix; the fee tie-out and sweep approvals; the revaluation journal with the rate source; and each draft and filed return with a trace to the figures it used. Paragraph 203 of Circular CSSF 26/906 expects reconciliations to be subject to review, and CASS 15.8.60R requires a UK firm to tell the FCA in writing without delay if it cannot perform a reconciliation or resolve a discrepancy. A close that keeps this evidence as it goes produces the auditor's file as a by-product rather than a separate project.

What should a payment company's month-end close checklist include?

These checks cover the customer money, multi-entity and regulatory items that an ordinary close checklist leaves out.

• Last daily customer funds reconciliation for the month signed off for every entity and currency.
• Cut-off time and time zone documented and applied to every processor and bank.
• Processor settlements agreed to bank receipts, with every payout in transit listed and dated.
• Refunds, chargebacks and processor reserves posted and agreed to processor reports.
• Fees agreed three ways: calculation, revenue posted and amount swept out of customer accounts.
• No unexplained excess or shortfall in any safeguarded or FBO account.
• Intercompany balances agreed by both entities in the same currency before consolidation.
• All foreign currency monetary items revalued at one closing rate source and time.
• Regulatory figures drafted from the reconciled numbers and traced to them line by line.
• UK safeguarding return inside 15 business days; MSB Call Report inside 45 days of quarter end; CSSF monthly table on schedule.
• Second-person review of every reconciliation and return, and the evidence pack filed before the period is locked.

Frequently asked questions

How is the month-end close different at a payment company?

A payment company holds customer money that must already be reconciled every day, so its close starts from the last daily reconciliation of the month and adds settlement, intercompany, fee sweep and FX revaluation work across several entities and currencies, with regulatory returns drawn from the same figures.

How long should a payment company's month-end close take?

Ten working days is a workable target for a group with several regulated entities, provided customer funds are reconciled daily. The UK safeguarding return allows 15 business days after month end, which leaves a margin after a ten-day close.

When is the UK monthly safeguarding return due?

Within 15 business days of the end of each calendar month, under SUP 16.14A.3R. A firm does not submit one for the month in which it becomes a safeguarding institution.

When is the NMLS MSB Call Report due?

Sections I to III are due 45 days after the end of each calendar quarter. Section IV(a), on transaction destination countries, is due annually, 45 days after the end of the fourth quarter.

How are foreign currency customer balances revalued at month end?

Under IAS 21, foreign currency monetary items, which include bank balances, customer e-money liabilities and intercompany loans, are translated at the closing rate at the end of each reporting period, with exchange differences recognised in profit or loss.

Do intercompany balances create FX gains or losses on consolidation?

Yes, where the two entities have different functional currencies. IAS 21 paragraph 45 says an intragroup monetary balance cannot be eliminated without showing the results of currency movements in the consolidated accounts.

Why must fees be swept out of customer accounts?

Once earned, fees are the firm's own money. Leaving them in a customer account mixes them with customers' funds: CASS 15.8.50R requires an excess to be withdrawn, and Circular CSSF 26/906 paragraph 210 names fees and commissions as funds that must not be mixed with users' funds.

What evidence should a payment company keep from each close?

For each entity and currency: the last daily customer funds reconciliation with reviewer sign-off, the settlement reconciliation and timing items, the intercompany matrix, the fee tie-out and sweep approvals, the FX revaluation with rate source, and each return traced to its figures.
