Tax firm run by SNP’s auditors accused of potentially running avoidance scheme

Company challenged over advice that one expert says will enable families to avoid paying tax on private school fees

A boutique tax advisory firm run by the Scottish National party’s new auditors has been accused of potentially running a tax avoidance scheme to help parents who are paying private school fees.

Signature Tax, an offshoot of AMS Accountants Group, offers clients “tailored tax solutions” on its website, including advice on paying fees in a “tax efficient manner”.
