HMRC Enquiry Defence

Avalon Tax offers a credible and valuable option for businesses seeking assistance with HMRC R&D tax enquiries. 


The company possesses extensive expertise in this domain, led by our tax-qualified CEO, who has a distinguished background within HMRC and the Inland Revenue stretching back over 30 years. 


Jonathan’s experience includes serving as an HMRC Tax Inspector, Senior Tax Inspector, and national Compliance Project Board lead, working in close collaboration with the HMRC compliance departments in WMBC and ISBC. He has personally managed hundreds of tax enquiries, both inside and outside HMRC, and led on R&D related compliance projects whilst within HMRC. This experience provides us with valuable insights into HMRC's current R&D tax enquiry campaigns and helps solidify Avalon Tax's reputation as a valuable ally if you are faced with an HMRC enquiry.


We help R&D tax consultants and advisers manage their R&D tax relief enquiry needs. We also work directly with individual claimant companies who have been selected for an R&D tax enquiry from any HMRC department, including Fraud Investigation Service (FIS).


Avalon Tax is a reliable and trustworthy partner for any business seeking dependable R&D tax enquiry support.
