Global VAT & Tax Strategy Weekly: 2 September 2026 : EU E-Commerce Milestones, UK VAT Filing Month & Cross-Border Compliance

TITLE: Key UK VAT Deadline, EU E-Commerce Growth, and Upcoming Compliance Changes

This week, prioritise your UK VAT return and payment due on 7 September 2026. Then review the European Commission’s latest e-commerce VAT figures, prepare for France’s e-reporting requirements, and monitor two UK consultations that could affect customs operations and tax error correction.

The immediate focus is simple: reconcile your records, file accurately, and document any known errors before deadlines pass.

Your 7 September UK VAT deadline comes first

Action required by 7 September 2026: Submit your VAT Return and ensure payment reaches HMRC for a quarterly accounting period ending 31 July 2026.

HMRC’s standard rule is that online VAT returns and payments are usually due one calendar month and seven days after the accounting period ends. For a period ending 31 July 2026, this produces a deadline of 7 September 2026.

Use HMRC’s VAT return guidance to confirm your own deadline. You must submit a return even if there is no VAT to pay or reclaim.

Complete these checks before filing:

1. Reconcile sales data. Match your bookkeeping records to Shopify, Amazon, eBay, WooCommerce, TikTok Shop, or other platform reports.
2. Check payment records. Compare gross sales, refunds, chargebacks, fees, and settlements against your bank statements.
3. Review imports. Match customs entries, import VAT statements, duty records, and postponed VAT accounting data.
4. Verify VAT treatment. Check standard-rated, zero-rated, exempt, outside-the-scope, and reverse-charge transactions.
5. Review currency conversions. Confirm that foreign sales and expenses use the correct exchange rates.
6. Submit through compatible software. Most VAT-registered businesses must keep digital VAT records and submit through Making Tax Digital-compatible software.

Do not leave payment until the last minute. HMRC requires the payment to reach its account by the deadline. Your bank transfer may need additional processing time.

For businesses searching for dependable vat return services UK companies can rely on, the priority is not just submission. It is maintaining a repeatable process that connects platform data, invoices, bank records, and import documents before every filing.

EU e-commerce VAT reached a new milestone

Published 31 August 2026: The European Commission released its Report on the application of the VAT e-commerce package for 2025.

The figures show continued growth in the One Stop Shop and Import One Stop Shop systems:

• Total VAT declared through OSS and IOSS reached EUR 38.8 billion in 2025.
• This was a 17% increase from EUR 33.1 billion in 2024.
• The Union scheme accounted for EUR 27.9 billion.
• The non-Union scheme accounted for EUR 3.2 billion.
• IOSS accounted for EUR 7.7 billion, up 22% from EUR 6.3 billion.
• More than 193,000 traders were registered by 31 December 2025.
• Registrations included 173,630 under Union OSS, 6,076 under non-Union OSS, and 13,733 under IOSS.
• The number of registered intermediaries reached 1,394.
• Cumulative VAT declared through the schemes since July 2021 reached approximately EUR 125.45 billion.

Turn EU growth into better controls

The statistics confirm that OSS and IOSS are now central to cross-border VAT compliance. They also show why accurate transaction data matters.

If you sell to EU consumers, complete this review:

1. Map each sales flow. Identify where goods are stored, dispatched, imported, and delivered.
2. Separate domestic and cross-border sales. Do not combine local VAT returns with OSS transactions.
3. Check the correct scheme. Assess whether Union OSS, non-Union OSS, or IOSS applies to each transaction.
4. Validate customer location evidence. Keep the records needed to support the consumer’s Member State and VAT rate.
5. Reconcile OSS data to platforms. Compare declared values with marketplace reports, payment processors, and fulfilment records.
6. Review low-value imports. Confirm that IOSS data, customs information, and customer VAT charges are aligned.

OSS can simplify reporting. It does not remove the need for transaction-level records.

Prepare now for the next ViDA milestones

From 1 January 2027: Certain OSS and IOSS registration-data amendments will apply.

From 1 July 2028: The main changes to OSS, IOSS, electronic reporting, and the transfer of own goods scheme will apply.

The European Commission adopted Commission Implementing Regulation (EU) 2026/1869 on 27 July 2026. It amends the operating rules for the special VAT schemes under the Single VAT Registration pillar of VAT in the Digital Age.

The regulation introduces the transfer of own goods scheme and further harmonises registration and electronic reporting data.

Do not wait until 2028 to prepare. Start by documenting:

• Which entities own stock in each country.
• How stock movements are recorded.
• Which warehouses and fulfilment providers are used.
• How platform reports are transferred into your accounting system.
• Which VAT registrations and OSS returns cover each transaction.
• How corrections are approved and retained.

This preparation will reduce disruption when reporting formats and scheme rules change.

France e-reporting now affects larger foreign businesses

From 1 September 2026: Large and intermediate-sized enterprises without a French permanent establishment may need to report transaction data through an authorised platform when they are liable for French VAT.

The French tax administration explains the position for foreign companies without a permanent establishment. These businesses are generally outside the French e-invoicing requirement, but they can still have e-reporting obligations for transactions treated as taking place in France.

The next phase begins on 1 September 2027 for micro-enterprises, very small enterprises, and SMEs. Businesses may be able to opt in earlier.

Review these points now:

1. Confirm your French company-size classification.
2. Identify French taxable supplies for which your business is liable for VAT.
3. Check whether OSS removes the need to report certain B2C transactions.
4. Select an authorised PDP or other approved platform where required.
5. Prepare transaction and payment data in the required format.
6. Reconcile e-reporting totals to French VAT returns and general ledger records.

The penalty for each missed transmission is EUR 50
