Ms MacDougall, who has worked in tax for 15 years, will head up the firm’s Scotland operations from Lismore in the Scottish Highlands.

An author of Bloomsbury tax guide Inheritance Tax in Scotland, the self-confessed “tax geek” will provide expert support in inheritance tax planning, trust and estate advisory, and international mobility, alongside bespoke personal and corporate tax planning.

The former doctor has sought changes to non-domicile and Additional Dwellings Supplement (ADS) legislation in both the UK and Scotland respectively for unjustly disadvantaged clients. She has also spoken at a Women in Business event and to students.

Commenting on her appointment, Ms MacDougall said: “I love a new challenge and Forbes Dawson’s reputation as a leading private client tax specialist with its technical expertise and enthusiasm for knowledge-sharing perfectly suits my desire to provide innovative solutions to complex tax issues.”

Joint managing partner Andrew Marr added: “As a firm, we advise business owners and their families across the whole of the UK and internationally.

“Not only will Brona’s unique background and extensive tax experience help us to manage the growing demand for our advisory services, but her expertise in Scottish taxes and complex estate matters will strengthen our offering throughout the UK.

“The appointment supports the company’s ambitious growth plans, opening the opportunity to extend its presence north of the border through the additional support to Scottish clients Brona can offer.”

Founded in 2012, Forbes Dawson is one of north-west England’s largest independent tax-only consultancies, providing expert advice and business support.
