MM Business and Tax Consultancy

Welcome to MM Business and Tax Consultancy, a leading tax advisory firm headquartered in the heart of London, UK.

We are dedicated specialists in helping businesses of all sizes thrive in the complex UK tax environment. With a focus on tax returns, VAT compliance and issues, and full accountancy services, we deliver proactive, personalised solutions that ensure full compliance while unlocking every legitimate opportunity to reduce your tax burden and improve cash flow.

Our Expertise

We provide comprehensive support across a wide range of services, including:

  • Preparation and filing of personal, corporate, and partnership tax returns (including Self Assessment and Corporation Tax).
  • Expert guidance on VAT registration, returns, partial exemption, cross-border transactions, and specialist reclaims.
  • Reliable bookkeeping, management accounts, financial reporting, and year-end accounts to keep your records accurate and audit-ready.

What truly sets us apart is our proven success in helping businesses reclaim millions in overlooked tax reliefs and VAT refunds. We specialise in maximising claims under key UK schemes such as:

  • Research & Development (R&D) Tax Credits (including the merged scheme and enhanced support for R&D-intensive businesses).
  • Capital Allowances — taking full advantage of the new 40% First-Year Allowance for qualifying plant and machinery investments (effective from 1 January 2026), alongside the £1 million Annual Investment Allowance and other incentives.
  • Employment Allowance, Annual Investment Allowance, and additional reliefs to optimise your tax position.
