Do I Need to Submit Intrastat Declarations After Brexit?

Understand whether your UK e-commerce business must submit Intrastat declarations for EU trade post-Brexit. Learn about current thresholds, commodity codes…

Yes, if your business exceeds the current thresholds for arrivals or dispatches of goods with EU countries you must submit Intrastat declarations in addition to normal VAT returns. The requirements remain in place after Brexit because the UK treats EU trade as neither fully domestic nor fully international for statistical purposes.

Many early-stage e-commerce founders find the rules confusing, especially when first scaling cross-border sales. This guide explains the key concepts in practical terms, the information you need to provide, and the steps you can take to simplify compliance without overpaying for specialist help.

What Intrastat Actually Is

Intrastat is the system used to collect statistical data on the physical movement of goods between the UK and EU member states. It is separate from VAT accounting and customs declarations. HMRC uses the collected data to produce official trade statistics that inform government policy and EU-wide reporting.

Unlike customs declarations, Intrastat does not usually involve paying duties. It is a reporting obligation only. The rules apply to both goods you sell to EU customers (dispatches) and goods you buy from EU suppliers (arrivals). You must report at the level of individual commodity codes rather than simply total sales or purchases.

Current Thresholds and Why They Matter

Separate thresholds exist for arrivals and for dispatches. When the value of your EU arrivals or dispatches in a calendar year exceeds the current threshold you must begin submitting Intrastat declarations from the month the threshold is crossed. Thresholds change periodically, so always check the latest figures on GOV.UK before relying on last year’s numbers.

Most new e-commerce sellers start below the thresholds and can focus on basic VAT recording. Once monthly EU trade consistently exceeds several hundred thousand pounds the obligation usually begins. Reaching the threshold in one category does not automatically trigger the other. Track both arrivals and dispatches separately throughout the year.

Practical tip: Set up a simple spreadsheet column that tags every EU invoice with its direction (arrival or dispatch) and estimated commodity code. Review the running total each quarter so you are not surprised in December.

Commodity Codes – Getting Them Right

Every physical product must be classified using an 8-digit commodity code from the UK Global Tariff. The first six digits are usually the same as the EU’s Combined Nomenclature; the final two digits can differ. Using the wrong code is one of the most common reasons for rejected declarations.

To find the correct code:

  • Start at the GOV.UK Trade Tariff search tool
  • Enter a clear description of your product (for example “men’s cotton t-shirt, knitted, 180 gsm”)
  • Follow the decision tree until you reach an 8-digit code
  • Save the code and a short description in your product database

Once you have more than a handful of SKUs, consider adding the commodity code field to your e-commerce platform or accounting software. This reduces errors when preparing monthly returns. If you import or sell complex items such as multi-part kits, check whether the code applies to the complete article or to its individual components.

Simplified Procedures and How to Use Them

HMRC offers two levels of simplification that can reduce the data you must submit. The first is the simplified Intrastat procedure, which allows fewer statistical details on low-value transactions. The second involves using VAT data to substitute for some Intrastat fields when the nature of the goods is straightforward.

To use simplified procedures you must still register for Intrastat but you can apply for authorisation via the online service on GOV.UK. Approval is usually granted if your records are accurate and you can demonstrate that full reporting would be disproportionate. Even with simplification you must still provide the 8-digit commodity code, the value, the net mass (in kilograms) and the country of origin or destination for each line.

Many UK startups use the simplification for the first year after crossing the threshold while they improve their internal data quality. Review the exact conditions each year because the permitted tolerances and value limits can change.

Step-by-Step: Preparing and Submitting Your First Declaration

  1. Register for Intrastat on the HMRC online service using your Government Gateway account. You will receive an Intrastat ID.
  2. Collect monthly data: invoice date, commodity code, EU country, value in sterling, net mass in kilograms, and nature of transaction code (usually 1 for purchase or sale).
  3. Convert all values to sterling using the HMRC monthly exchange rates published on GOV.UK.
  4. Validate the file using the free Intrastat validation tool provided by HMRC or compatible accounting software.
  5. Submit by the deadline – normally the 21st day of the following month. Late submissions can result in penalties.
  6. Keep detailed records for at least four years in case of enquiry.

Start with a test submission for a month where you know the figures well. Many accounting platforms now have built-in Intrastat export modules that map directly from sales and purchase ledgers. Test the export early rather than in the first compliance month.

Common Pitfalls for E-commerce Sellers

Low-value consignments sold via online marketplaces are still reportable if they cross the threshold. The fact that a fulfilment centre in Germany handles the parcel does not remove the obligation to report the movement from the UK.

Dropshipping from EU suppliers can create both an arrival (when stock enters the UK) and a dispatch (when you sell it onward). Record both legs accurately. Returns from EU customers must also be reported in the month they physically cross the border, often using a negative value or specific return code.

Currency conversion errors and missing net mass figures are frequent reasons for automatic rejection. Net mass must reflect the weight of the goods alone, excluding packaging. If you sell by the unit, convert your average unit weight into the total for the month.

When to Get Help and Where to Find It

For most straightforward e-commerce businesses the GOV.UK Intrastat guidance, the Trade Tariff tool and your accounting software are sufficient. If you sell highly regulated goods, use many different commodity codes, or trade in both directions at high volume, consider a short consultation with an accountant who specialises in international trade.

Free webinars and recorded guidance are available directly from HMRC. The online helpdesk can answer specific questions about your commodity codes once you have attempted classification yourself. Keep records of all correspondence.

Loomworks in Liversedge offers selected early-stage founders free desks, a registered address and mentoring; many of their e-commerce cohort use the on-site bookkeeping support to set up Intrastat processes correctly from day one.

Frequently asked questions

Do I have to submit Intrastat if I only sell digital products?

No. Intrastat applies only to the physical movement of goods. Purely digital downloads, software licences and services are outside the scope. You still need to account for VAT on EU sales of digital services under the VAT MOSS scheme.

What happens if I miss the Intrastat submission deadline?

HMRC can issue penalties for late or missing declarations. The size of any penalty depends on how late the return is and your previous compliance record. Submitting a nil declaration when you have no trade is still required once you are registered.

Can I use my normal VAT return instead of Intrastat?

No. The VAT return shows only total values. Intrastat requires a breakdown by commodity code, country, net mass and nature of transaction. Even if you use simplified procedures you must still file a separate Intrastat return.

Do I need to register for Intrastat every year?

Once registered you usually remain registered until your trade falls consistently below the threshold for two complete calendar years. You must still submit declarations every month even if some months have zero activity.

How do I classify products that could fit more than one commodity code?

Choose the code that most specifically describes the goods according to the tariff rules. When in doubt, request a Binding Tariff Information ruling from HMRC. This gives legal certainty and should be quoted on future declarations.
