Knowle, Solihull · serving Birmingham & the West Midlands ICAEW Chartered Accountants & Registered Auditors

A chartered firm built around the biggest change in UK tax for 30 years

iTSA Digital Tax is a firm of ICAEW chartered accountants and registered auditors on Knowle High Street in Solihull. We named the firm after ITSA. Income Tax Self Assessment, because the system being replaced by Making Tax Digital is exactly the thing we set out to specialise in.

Why we started

Making Tax Digital for Income Tax is the biggest change to personal tax since Self Assessment arrived in 1997. From April 2026 it began replacing the annual tax return with quarterly reporting, and by April 2028 it will cover anyone with more than £20,000 of self-employment or rental income.

Most accountancy firms are treating it as a problem to deal with next year. We thought that was the wrong answer. A few hundred thousand sole traders and landlords are about to be told they now have five filing deadlines a year instead of one, most of them have never used accounting software, and almost none of them know it is coming.

So we built a practice around it: the software set-up, the quarterly filing, the deadline management and the final declaration, handled as one fixed monthly fee. Alongside the full range of work a chartered firm does, company accounts, Corporation Tax, VAT, payroll, audit and advisory.

How we work

Every client has a named chartered accountant who knows their business and stays with them. Our directors work directly with clients and intend to keep it that way as the firm grows, because it is the part of the service clients tell us matters most. Every set of accounts and every piece of tax advice is reviewed and signed off by a Fellow of the ICAEW before it leaves the firm, and we are registered to carry out statutory audit work.

What we hold ourselves to

  • A price before the work, not after

    Every engagement is a fixed fee, agreed in writing before anything starts. We do not bill by the hour, because hourly billing punishes you for asking questions and rewards us for being slow.

  • A named person who answers

    You will have one accountant who knows your business and answers the phone. Not a ticketing system, not a rotating account manager, not an offshore processing team.

  • Early, not late

    The value in an accountant is almost entirely in what they tell you before the year end. We flag deadlines months out and raise planning points while they can still change the outcome.

  • Plain English, always

    If you do not understand what we have told you, we have not done our job. We will explain a Section 24 restriction or a marginal relief calculation as many times as it takes.
