EQ Accountants, which has offices in Dundee, Forfar, Cupar and Glenrothes, recently secured its 300th claim for R&D tax credits.
The seven-strong specialist team has now faciliated in excess of £16m of tax savings for companies in Scotland.
These have included £251,000 for a niche engineering business, £185,000 for a textiles manufacturer and £75,000 for a local soft fruit grower.
David Morrison, head of EQ taxation, said: “Many businesses think that R&D tax credits only apply to pure research but there are so many sectors who are entitled to make a claim.
“Businesses need to innovate to stay ahead and, as long as the company is seeking technological advances, they have a strong chance of qualifying.”
