Founded in 1969 The CWM Partnership has spent over five decades doing one thing well: helping businesses and individuals navigate the complexities of tax, accounting and compliance — with straight answers, practical advice and genuine care for our clients’ success.

We are Chartered Certified Accountants based in Sanderstead, South Croydon, and proud to combine that long-standing expertise with a thoroughly modern, digital approach to accountancy. Whether you are a limited company, self-employed, a landlord, or simply need help with your personal tax affairs, we have the experience and the tools to help you.

For Limited Companies and Their Directors

Running a limited company brings its own distinct set of responsibilities, and we understand them well. From preparing statutory accounts and corporation tax returns to advising on the most tax-efficient structure for director remuneration — balancing salary, dividends and pension contributions — we help owner-managed businesses make the most of their position.

We also work closely with directors on their personal tax position, because the two rarely sit neatly apart.

For growing businesses considering whether to incorporate, or established companies looking to plan ahead, we bring the kind of rounded, experienced perspective that only comes from decades of working with owner-managed businesses of every shape and size.

For the Self-Employed and Landlords

If you run your own business as a sole trader or partnership, or you let residential or commercial property, we provide everything you need to stay compliant and tax efficient.

We are also fully prepared to guide you through Making Tax Digital for Income Tax, which is being phased in between 2026 and 2028 and will fundamentally change the way self-employed individuals and landlords report their income to HMRC. Quarterly digital submissions will replace the annual self-assessment return for most, and the transition requires the right software and the right adviser. We are already helping clients get ready, and whether you are at the beginning of that journey or need to move quickly, we will make the process straightforward.

If it touches your finances, we can help.

Part of Your Team — Without the Overhead

We understand that most small businesses cannot justify a full in-house finance team. That is precisely where we come in. We work as an extension of your business: getting to know you, understanding how you operate, and being available when you need us — not just at year end.

All our staff are trained to give you answers you can rely on across a wide range of subjects. Where a matter calls for specialist input — a larger firm for a one-off complex assignment, an independent financial adviser, or a solicitor — we will connect you with trusted associates and remain part of the conversation. Small practice, broad reach.

Old School Values. New School Tools.

What we believe sets us apart is the combination of genuine longevity and genuine modernity. We have the institutional knowledge that only comes from decades of doing this work across hundreds of businesses and individuals. We also invest in the latest cloud accounting platforms, digital workflows and MTD-ready systems, so that our clients are always in the best possible position — whether that means being compliant today or being ready for what is coming tomorrow.

We will always be direct with you, always be accessible, and always push forward alongside you.

Whether you are an architect, barrister, builder, creative designer, consultant, engineer, hairdresser, musician, property developer, retailer, restaurateur, tailor or run an online business — from day one we will understand what you need and work to give you more time to focus on what you do best.
