How we can help

  • Addressing VAT issues for your projects
  • VAT support during HMRC investigations and reviews, tribunal appeals, and compliance challenges in regulated sectors like financial services
  • Identifying VAT opportunities for saving money and conducting due diligence
  • Handling VAT penalties and disputes
  • Registering for VAT so you are compliant.

Proactive VAT advice

We offer expert advice on property transactions, construction projects, and corporate reorganisations and on more specialist areas such as cross-border trade, hospitality, and luxury assets including yachts and aircraft.

VAT has undergone major changes in recent years. The UK’s departure from the EU introduced new complexities, especially for importers and exporters with Northern Ireland’s distinct VAT regime and One Stop Shop (OSS) rules creating fresh compliance risks for UK-based businesses selling to EU consumers.

Sectors like construction have also faced a significant shift, with new rules on reverse charge VAT introduced in March 2021, changing how VAT is accounted for within supply chains.

Our expertise

Drawing on deep sector experience, we deliver tailored advice that helps clients plan effectively, maximise reliefs, minimise risk, and resolve disputes efficiently. Whether you need help with VAT planning and registration, handling an HMRC inspection, or managing VAT within a transaction, we’re here to support you every step of the way.

Frequently asked questions on VAT

VAT (Value Added Tax) is a transaction-based tax with complex rules that vary by sector, region, and transaction type. Specialist legal advice helps businesses stay compliant and avoid costly mistakes.

Every business and every project will have a large number of transactions, both purchases and sales, which should be understood for VAT, captured in the VAT record and reported to HMRC.

The VAT on sales must be recorded correctly by the seller. The VAT claimed on purchases must be recorded correctly, including identifying incorrect VAT charges by suppliers, identifying when to claim and when not to claim (including partial exemption and Capital Goods Scheme adjustments), and identifying when purchases are treated as sales under the various reverse charge mechanisms.

There are also obligations regarding when to register for VAT and when to deregister, when to submit and pay returns, how invoices are laid out and how VAT returns are submitted (Making Tax Digital or MTD).

Does that mean everything HMRC tells you to do is an obligation?

If you think HMRC is wrong, you can stand your ground and argue your case, preferably with an experienced adviser in support.

You must register for VAT if your taxable turnover exceeds £90,000 over the past 12 months, or if you expect it to go over that threshold within the next 30 days.

You’ll also need to register regardless of turnover if all of the following apply:

  • You are based outside of the UK
  • Your business is based outside the UK, and
  • You supply goods or services to the UK or plan to do so within 30 days

This applies to non-established taxable persons (NETPs) overseas businesses trading in the UK.

Even if you don’t meet the threshold, you can voluntarily register for VAT, which may allow you to reclaim VAT on business costs.

You won’t need to register if you only sell VAT-exempt or ‘out of scope’ goods and services.

Once registered, you’ll be responsible for charging VAT correctly and paying any VAT due to HMRC.

HMRC will investigate a business to ensure it’s VAT records and liabilities are correct. This will happen routinely (every few years), or because HMRC has concerns (every year or so), or because there is a specific question HMRC wish to answer.

Reliefs don’t really exist in VAT as they do for direct taxes. There are different rates of VAT with different advantages and disadvantages, some of which allow no VAT to be accounted for on a sale.

There are simplifications and special methods, where for example complex VAT calculations can be avoided or made more practical. There are also exceptions where VAT registration can be avoided. Planning a project to capture a balance of these various advantages can save time and money.

HMRC have a variety of ways of penalising a taxpayer who has put a foot wrong, such as failure to notify HMRC of a requirement (e.g. applying for VAT registration on time), failure to submit a VAT return or pay a VAT liability on time, making an error in calculating VAT liabilities on sales or recovering VAT on purchases, or compounding these mistakes with deliberate or evasive behaviours.

A taxpayer can also be assessed for interest for VAT which HMRC considers it did not receive on time.

There are ways to reduce or eliminate penalties, but the right approach from the earliest stages will produce the best result.

Since Brexit, businesses importing and exporting goods face new VAT rules, including import VAT, OSS compliance, and specific challenges for Northern Ireland, which now operates a separate VAT regime.

Client stories

It’s so rare to find a VAT adviser who will fight for you. You approach complex VAT issues positively, explaining the rules and why they aren’t clearcut, then help our clients to fight and support their view. It’s very rare and we really value it.

Hussein Bhaiji, Managing Partner at Merit Accountants The Accountancy People

One of our team helped a recruitment business avoid paying a £54m VAT liability by working closely with HMRC which resulted in the business avoiding the VAT risk. In another case, we successfully defended a hotel against a charge that it had reduced its VAT by too much for long-stay guests. HMRC conceded on the steps of the Tribunal. 

Avoidance of £54m VAT liability

A member of our VAT team saved millions of pounds for both buyers and sellers of businesses by recovering input tax as fully as possible and ensuring that VAT liabilities were not created unnecessarily when a business is bought or sold. This has also involved resolving VAT risks. 

Recovery of input tax following acquisitions

One of our specialists successfully helped a construction firm to resolve several HMRC VAT-related enquiries relating to a number of complex multi-million pound projects. We have helped numerous businesses facing HMRC VAT inspections, including specific HMRC challenges appealed to Tribunal. 

Advised on VAT regarding multi-million pound development

Online trading has increasingly become the target of anti-avoidance rules over the years.  While this is necessary, it has meant higher and higher burdens. We supported an online platform in its evolution to address these new rules and take on itself the pressures faced by the online traders using its platform.  

Guiding an online platform through VAT anti-avoidance changes

We assisted the government to provide post-Brexit VAT advice to numerous small and medium sized enterprises throughout the West Midlands, from those below the VAT registration limit to multi-million pound international businesses.  

Supporting West Midlands SMEs with post-Brexit VAT

We steered a client away from a significant VAT bill on a £30m property development project and into a safe position. We acted under high time pressure, but our advice enabled the project to proceed on time.  

Avoiding a VAT liability on a £30m property development

We assisted a UK PLC (over $10 billion worldwide capitalisation) with its cross-border supplies, including successfully resolving HMRC investigations and reducing its UK VAT liabilities. The saving in UK VAT has been millions of pounds each year.
