What YesTax does

YesTax (legal entity TFF Tax Limited) is a Sheffield-based specialist tax consultancy founded in January 2019, focused exclusively on UK tax incentives including R&D Tax Relief, Patent Box, Video Games Tax Relief, and Capital Allowances. The firm advises UK companies across 18+ industry sectors on identifying, preparing, and managing claims, with services delivered by a team of 13-14 qualified professionals including Chartered Accountants, Chartered Tax Advisers, ATT-qualified specialists, and solicitors. The company's technology is described as market-leading tax relief software for claim preparation and management, with white-label software for partner firms listed as in development.

The firm's go-to-market is sales-led, explicitly rejecting cold calling in favour of word-of-mouth, professional referrals, and the YesPartner programme for accountancy firms. Partner firms receive dedicated business development support, bi-annual training, and marketing materials, generating a recurring referral stream. YesTax operates a fee-based professional services revenue model with bespoke engagement letters and no publicly disclosed pricing.

Since October 2022, YesTax has been owned by its employees via an Employee Ownership Trust (EOT), making it the only employee-owned specialist tax advisory firm in the UK. The EOT structure is paired with the Guiding Light Foundation, which receives 2.5% of turnover for charitable causes, primarily child rescue and support through a Nepal-based partner. The company holds three Accounting Excellence Awards (Best New Tax Practice, New Firm of the Year, Brand of the Year) and reports cumulative client outcomes of £143m in R&D tax savings, £12.2m in Capital Allowances savings, and £11.7m in Patent Box savings across its client base.
