Overview

How to change your VAT service provider

Is your current VAT service provider falling short? Whether they are missing deadlines, neglecting communication, or facing financial difficulties, it is crucial to address these issues promptly. Delayed VAT submissions and poor service can lead to penalties, audits, and potential loss of access to schemes such as the Import One Stop Shop (IOSS).

Disruption in your VAT services is stressful, and switching can be necessary. Changing providers is not always straightforward because of timing, portals, and record handovers.

The sections below help you stay in control of the process.

VAT tips

Red flags for VAT agents

You may notice signs that it is time to find a new VAT provider, especially if your current agent shows signs of financial distress. Being caught off guard can jeopardise access to records and tax portals you need for compliance.

Inconsistent billing

Frequent billing changes or sudden price increases can indicate strain. Delayed invoicing is also a concern, as cash-flow problems often disrupt normal billing cycles.

High staff turnover

Difficulty reaching anyone by phone or email, or support tickets left unanswered, can signal operational problems. That often affects communication when you need it most.

Portal downtime

Inconsistent access to your agent’s systems or repeated outages should be taken seriously.

Do I need an EORI registration in specific countries?

You generally register at the first point of entry for goods into the EU, or in Great Britain when importing into the UK.

Gossip and rumours

In financial services there is often some truth behind market talk. Speculation alone should not drive decisions, but combined with other red flags it may be time to evaluate alternatives — through networks, social channels, or peers.

How can VAT consultancy help when switching VAT service providers?

Switching providers can be complex. With expert VAT consultancy, you can map risks, plan the handover, and keep filings compliant while operations continue.

Steps to change your VAT provider

When you decide to switch, start by organising your documentation. Keep sales data accessible — you will need it during the transition. Then request copies of key records from your current agent.

Request copies of your records

Ask specifically for:

  • VAT records
  • VAT filings and returns
  • Correspondence with tax authorities
  • Confirmation of submissions

Having prior submissions to hand simplifies handover, especially in countries such as the Czech Republic and Germany. UK clients typically need their last HMRC submission so a new agent can take over.

Missing submissions, letters, or payments increases audit risk.

Ignoring authority correspondence can lead to penalties and interest. If you cannot produce past returns or invoices when asked, you may face repayment or assessment issues.

If you are VAT-registered in France

Your previous agent usually must remove you from their fiscal portal before your new provider can file. Skipping this step can delay compliance with the French tax authorities.

If your provider is unresponsive

Contact the tax authorities directly for copies of past filings, and provide proof of registration (VAT certificates, prior emails). Each country has its own process; some requests take weeks. Gather what you have — your new provider may help reconstruct missing filings, often for a fee.

Searching for a new VAT service provider?

While you organise documents and contact authorities, research alternative providers and shortlist carefully before you move.

If you suspect insolvency or withdrawal of service, act early. A clear plan makes exit smoother and reduces the risk of missed deadlines.

Once you choose a successor, review your current contract — notice periods, termination, and offboarding conditions.

1. Reliability

Check commercial registers and filings where available to understand financial health.

2. Transparency

Prefer clear reporting: filing copies, payment confirmations, and regular updates.

3. Proven track record

Look for sector experience, case studies, and reviews comparable to your situation.

4. Customer support

Responsive teams and strong client feedback are good indicators.

Gather your documents

  • Copies of VAT returns and filings
  • Submission confirmations
  • Sales data and transaction history
  • Authority correspondence
  • VAT registration certificates

If registered in France

Ask the current provider to release your portal access so the new agent can take over.

If registered for IOSS

Have your current intermediary deregister the IOSS number to allow a clean new registration.

If the provider is unresponsive

  • Contact tax authorities for past filings
  • Contact the IOSS registration body for deregistration where relevant
  • Reconstruct missing filings with your new provider

Check for outstanding VAT

  • Keep a calendar of filing and payment deadlines
  • Reconcile filings against deadlines
  • File and pay late items to limit further penalties
