I have been a personal tax client of AAB for a number of years and in that time they have guided me through the tax return process and provided me with specialist advice relating to my non-resident tax position.
Peter Williams
I instructed AAB to investigate a fraud which had occurred at a remote subsidiary of my institution. They acted promptly and with persistence in researching the financial background, providing me with excellent oral and written reports.
Director, Charitable Institution
On announcement from the Government that IR35 changes were to be postponed, AAB were in touch instantly to discuss the best way forward and to assist with the Company’s communication to contractors surrounding this.

If your business is notified by HMRC that they propose to undertake an enquiry, we’ll provide reassurance and ensure the matter is resolved as quickly and efficiently as possible.
Whether it’s a VAT enquiry or a Trade and Customs Compliance review, our indirect tax team have extensive experience of supporting our clients through this process. Our team includes ex-HMRC Officers with years of experience, so we’ll explain not only what to expect during the enquiry, but also why it has arisen. Whether you’ve received a request for a full on-site VAT inspection, or a more targeted enquiry focussing on one area or period, our specialists can help you collate the information needed to respond to HMRC.
This will include a review of the information to identify any issues and whether you should make any disclosures to HMRC. Using our knowledge of HMRC’s internal processes, we will always try to ensure that any disclosure you make will eliminate or mitigate any HMRC interest and penalties HMRC.
Our support includes:
If, following interaction with HMRC, you receive a challenge or unfavourable decision from HMRC on VAT, Customs Duty or any other indirect tax, we can help you with our practical and commercial approach to settling disputes.
If you haven’t had a visit or enquiry from HMRC for a number of years, or if there have been significant changes to the staffing or operation of your business, you may want the peace of mind of our VAT Health Check. Designed to address the areas covered by HMRC on visits, and more, it can provide assurance that your current processes and controls are robust or if necessary, pre-empt issues where they arise.

Given the risk of an HMRC PAYE & Employer Compliance Review, many businesses choose to bring in our experts. We carry out a health check review of internal processes and reporting procedures to highlight any inconsistencies and suggest changes to ensure compliance with current legislation and the interaction with HMRC’s guidance.
Such a review is invaluable for minimising the chance of HMRC highlighting any errors which could result in substantial liabilities and penalties.
As part of the health check, we also highlight any areas requiring voluntary disclosure to HMRC. This minimises the number of years HMRC can look back to recover underpaid liabilities on an error and reduces any penalties charged, in comparison to what HMRC which impose if they found the error themselves.
Our team of experts will work with your business not only to support you through any HMRC reviews if they arise, but also to ensure you’re fully compliant with current legislation, significantly reducing risk of a future HMRC tax investigations.

It’s the service you don’t know you need until it’s too late – but we’re here to change that.
HMRC carries out thousands of tax enquiries into UK individuals and businesses every year. Whilst these are often triggered because of a particular red-flag, HMRC can and do regularly select taxpayers for enquiries using their ‘super-computer’ HMRC Connect.
Whilst you may be confident your tax affairs are accurate and up to date, if you’re the subject of an HMRC enquiry you must respond to it, even if you’ve done nothing wrong.
The fees and costs of dealing with the enquiry are payable by you and cannot be reclaimed from HMRC. Hence why it’s wise to protect yourself against the costs of tax enquiry through the Tax Fee Protection Service. After all, you wouldn’t drive your car without insurance!
HMRC Connect identifies more than 80% of the taxpayers HMRC choose to investigate. The system collects data from 30 sources, including UK and offshore banks, Companies House, the Land Registry, estate agents, the DVLA and other licensing authorities, and social media.
The data can be instantly reviewed by more than 3,000 HMRC tax investigators to produce a financial fingerprint for any taxpayer. If there are any discrepancies between tax returns or business accounts sent to HMRC, a tax enquiry will inevitably follow. Tax enquiries started from ‘Connect’ have produced billions of pounds in additional tax over the last few years.
Using ‘Connect’, HMRC can now target enquiries more accurately than ever – but they still get it wrong sometimes. That’s why we will always challenge HMRC regarding their perceived risks for opening an enquiry when defending clients.

TAX FEE PROTECTION SERVICE – THE FACTS
Tax Fee Protection Service covers the enquiry fees for HMRC enquiries into a range of taxes, including Corporation Tax, Income Tax, PAYE/NIC, IR35, VAT, Inheritance Tax and many more.
Coverage will only be provided if the service is in place prior to the enquiry being issued by HMRC. It is therefore vital that taxpayers consider the risk of failing to invest in the Tax Free Protection Service.
The service covers up to £100,000 towards your fees for co-operating with an HMRC Enquiry.
Policies range from £180 – £600 annually per individual tax entity, including businesses with turnover of up to £25m. Discounts are available for group policies and specialist quotes can be provided for businesses with turnover in excess of £25m.
Finally, some taxpayers may opt to avoid paying professional fees and Tax Fee Protection Service altogether, opting to deal with the enquiry themselves. This is not recommended for taxpayers under enquiry, as we’ve seen many examples of individuals and companies having to pay considerably more tax, interest and penalties than they may have been liable for.
