About M&B · Est. 2000
Real accountants. Real answers.Real fast.
For over two decades, M&B Tax Services has been the back-office backbone for UK landlords, contractors and growing businesses — turning HMRC chaos into one calm, compliant inbox.
M&B Tax Services started in 2000 with a single, stubborn idea: accountants should answer their phones. We were tired of clients being passed between juniors, charged for emails, and left to decode HMRC letters alone.
Today we look after landlords, freelancers, contractors and limited companies across the UK — from first-time sole traders filing their CWF1 to property portfolios juggling SA105s and Section 24. Same phone number. Same people. Same plain English.
“We don’t bill by the email. We don’t speak in jargon. We just get the work done — and tell you when it’s safe to stop worrying.”

Why choose M&B
Four reasons clients stay for years.
We’ve built our practice around the things bigger firms keep cutting — phone calls, fixed prices, and people who actually know your file.
“M&B Tax Services Ltd took weekly payroll & CIS off our plate in a fortnight. Haven’t missed a deadline since, and the subbies actually get paid on a Friday.”
