Mark Stemp

Partner, Private Clients
London

I help individuals, families and business owners make informed decisions about their tax affairs. My advice is practical and commercially focused, with an emphasis on explaining complex tax issues in plain English so clients can take clear, confident action.

With more than 25 years’ experience in private client tax, I specialise in Income Tax, Capital Gains Tax, Inheritance Tax and SDLT planning. I have particular expertise in property taxation, trusts, family investment companies and succession planning. Whether a client is investing in property, planning for retirement or passing wealth to the next generation, my role is to help them achieve their objectives in a tax-efficient and sustainable way.

I work with high-net-worth individuals, landlords, entrepreneurs and family business owners and regularly collaborate with solicitors and financial advisors to deliver joined-up advice. 

Since joining Crowe in 2012, I have worked across both the London and Thames Valley private client teams. More recently, I have led the development of the firm’s national private client property tax offering and its strategy for Making Tax Digital for Income Tax. I regularly speak and write on property tax matters.
