EC Sales List and VAT return: what is the difference and how do they reconcile?
The EC Sales List (opgaaf ICP) specifies box 3b of the VAT return. Periods, the € 50,000 threshold, the reconciliation check and correcting a list.
The short answer
The VAT return and the EC Sales List (in Dutch: opgaaf intracommunautaire prestaties, ICP) are two different filings about the same transactions. In box 3b of the VAT return you declare the total of your supplies to and services in other EU countries. The EC Sales List is the specification of that total: per customer, with their VAT identification number and the amount.
For the same period those two amounts must be equal. If they differ, the client receives questions, and those questions end up at your firm.
Two filings, one set of books
The VAT return exists to remit or reclaim VAT. The EC Sales List exists to inform other EU member states: they check whether the customer declared the acquisition in their own country. That is why the list contains data the VAT return does not need, such as the customer's VAT identification number.
That difference in purpose also explains why the periods can differ. You may file the VAT return quarterly, for example, while the EC Sales List must be monthly once you exceed a threshold.
What you declare in box 3b
Box 3b of the VAT return contains supplies to and services in countries within the EU for which VAT has been reverse-charged to the customer. It concerns the net amount; there is no VAT against it, because the customer declares that in their own country.
What does not belong in 3b: supplies to private individuals in the EU (these fall under the distance selling rules and usually under the Union scheme), exports to countries outside the EU, and domestic supplies to a foreign customer holding a Dutch VAT number.
What the EC Sales List contains
Per customer: the VAT identification number including the country code, the total amount of intra-Community supplies in the period, and separately from that, the services. Additional situations such as supplies following a triangular transaction also have their own indicator.
The total of the EC Sales List for a period must equal what you declared in box 3b of the return for that same period.
Periods and the € 50,000 threshold
If you supply goods intra-Community, the list is monthly in principle. You may report quarterly if, in the quarter you are reporting on and in each of the four preceding quarters, you did not make more than € 50,000 of intra-Community supplies of goods per quarter. If you exceed the threshold in a quarter, you report monthly again from that quarter onwards.
The list must be submitted no later than the last day of the month following the period.
| Situation | EC Sales List period | Submission deadline |
|---|---|---|
| Supplies of goods above the threshold | Monthly | Last day of the following month |
| Supplies of goods below the threshold in the quarter and the four preceding quarters | Quarterly | Last day of the month after the quarter |
| Services only | Monthly or quarterly; annually only with a permit | Within 1 month of the chosen period |
Watch out for the combination that goes wrong in practice: a client on quarterly VAT returns who grows past the threshold and must therefore submit the EC Sales List monthly. The periods then diverge, and the reconciliation only works if you add the three months together per quarter.
The reconciliation check in three steps
- Add up per period. Add together the EC Sales Lists covering the same period as the VAT return.
- Compare with box 3b. The total must be equal. A difference of one euro is a difference too: it almost always points to an invoice in the wrong period or under the wrong box.
- Explain the difference before you submit. Find the cause in the books rather than adjusting the amount so that it matches.
Include this check in the standard monthly close, see Setting up the monthly close.
Common differences and their causes
| What you see | Likely cause |
|---|---|
| The list is higher than 3b | An invoice is in the list but was posted under 3a or as domestic in the return |
| 3b is higher than the list | A customer without a valid VAT identification number, so the line does not reach the list |
| A difference exactly equal to one credit note | The credit note was processed in a different period than the original supply |
| A structural small difference | Currency differences or rounding per invoice line |
| An amount under the wrong customer | The VAT number of an affiliated company used instead of the customer's |
Checking VAT identification numbers
The zero rate on an intra-Community supply stands or falls with a valid VAT identification number for the customer. Check that number for a new customer and periodically for existing ones, and keep the evidence of the check in the file. A number that was valid last year may have been terminated, for example after a reorganisation or bankruptcy.
This is exactly the type of check you can automate on the flagging side: let the software report that a number is missing or deviates, and let an employee assess what then happens to the invoice.
Correcting an EC Sales List
If a submitted list contains an error, you correct that list itself; that is a separate action alongside any correction of the VAT return. Two consequences to keep in mind:
A correction in the list without a correction in the return breaks the reconciliation, and a correction in the return without one in the list does the same. So always assess both. For the VAT side, see VAT correction (suppletie).
Corrections concerning customers feed through into the checks performed by the other member state. So inform the client when a correction may lead to questions from their customer.
What you automate and what you assess
| Automate | Assess |
|---|---|
| Adding up and reconciling 3b with the list | The cause of a difference |
| Flagging missing or invalid VAT numbers | Whether the zero rate was rightly applied |
| Monitoring the threshold per quarter | The switch to monthly reporting and communicating about it |
| Preparing the list from the sales ledger | Special situations such as triangular transactions |
Goods and services are not the same
Different rules apply to goods and to services, and that difference sits exactly where errors arise.
Intra-Community supplies of goods require evidence that the goods genuinely left the Netherlands. Without proof of transport the zero rate is open to challenge, regardless of a valid VAT number. The threshold determining monthly or quarterly reporting also applies to these supplies.
For services to businesses in the EU, VAT is reverse-charged to the customer when the place of supply lies in the customer's country. There are exceptions where the place of supply stays in the Netherlands, for example work on immovable property located here. Those exceptions do not belong in box 3b and therefore not in the EC Sales List either.
The practical consequence for the firm: record per client which types of supply occur and which treatment goes with them. Without that record, every employee assesses it anew, with differing outcomes.
What happens when it does not reconcile
A difference between box 3b and the EC Sales List surfaces in European control systems. The customer then shows an acquisition that does not match what they declared themselves, or the other way round.
The practical consequences escalate in this order: the customer contacts your client, the foreign tax authority puts questions to the customer, and the Dutch Tax Administration asks your client for an explanation. Even a correction without a substantive problem then costs time at three parties.
That is why the reconciliation check before submission is the cheapest moment. A difference you find yourself is an entry. A difference a foreign customer finds is a case file.
