Chartered Accountants & Chartered Tax Advisors 
based near Mayfair

Chartered accountants and registered auditors

For over 40 years we have been supporting local, privately owned small to medium sized businesses and their owners with an extensive range of accountancy services, including tax advice and business audits.

Mayfair is London’s most exclusive district, synonymous with class and sophistication. It is home to exclusive hotels, art galleries and restaurants, as well as world-famous retailers – including bespoke tailors on Savile Row and designer fashions on Bond Street.

We are proud to work with entrepreneurs and private clients based in one of London’s most prestigious neighbourhoods. As chartered accountants, chartered tax advisors and registered auditors we offer proactive advice to help ensure that a business can fulfil its potential, and its owners achieve their personal goals.

Essential business advice for start-ups

The first three years of any business are notoriously the hardest. Many start-up businesses do not make it beyond this initial phase due to poor planning and ineffective business decisions.

At Warrener Stewart we have helped many businesses overcome these initial hurdles, and go on to flourish and grow, including Osborne Samuel Ltd, a modern and contemporary art gallery based in the heart of Mayfair. With years of experience and connections in the area, we can also introduce you to other trusted professionals, such as Meaby & Co solicitors and others based in Mayfair, who can help support your company.

Tax advice for private clients

Our team of Chartered Tax Advisors can provide ongoing advice about your personal tax position. We work with a wide variety of private clients to advise on a range of personal tax issues, from setting up trust funds following an inheritance, through to advice on developing a property portfolio.

Whatever your tax challenges, we are confident that we can devise and help you to implement the most advantageous solutions to protect and augment your wealth.

US tax return filing

Our tax team is also authorised to advise on American tax issues. We have several Enrolled Agents licensed by the US Federal Government available to file US tax returns for Americans living and working in Mayfair.

We also have an Authorized Acceptance Agent, licensed by the American tax authority (the IRS), to help non-residents apply for their individual tax numbers.

Registered auditors for Mayfair

At Warrener Stewart our registered auditors conduct audits for many firms around Mayfair. We also work for several regional branches of large multi-site organisations located in south west London (SW1, SW3 and SW7).

Although an audit may not be legally required for small, privately owned limited companies, it can be highly beneficial. The outcome can inform improved business performance and help guard against risk. It can also build confidence and credibility which is of particular interest to any company considering expansion or looking to sell.
