As a Croydon tax accountant we help East Croydon commuters with side income, self-employed carers and cleaners, small retailers and food businesses, and landlords across a borough with a large rental market. Many clients come to us after receiving their first HMRC letter, and we make the process straightforward.
Self-employed carers, cleaners and support workers can claim travel between clients, uniforms, equipment and phone costs. We keep returns simple and make sure you only pay tax on genuine profit. See self-employed accountants and add bookkeeping if you would like records kept for you.
Croydon has a large stock of rented flats, including many new developments. We prepare landlord returns, claim service charges and agent fees and explain mortgage interest relief. Mortgage interest relief is a 20% tax credit, rising to 22% from April 2027 when property income gets its own 22%, 42% and 47% rates. More on landlord tax returns; for missed rent, the Let Property Campaign.
HMRC sends letters when its data suggests untaxed income, such as rent, online sales or overseas savings. Do not ignore them. We review the letter, check your records and either file the missing return or explain why nothing is due. See our guide to HMRC letters about income abroad.
If you run a business with someone else, the partnership files an SA800 and every partner reports their share. We handle the whole set, together. See partnership tax returns.
Sold a flat, shares or an inherited property? Gains over £3,000 are taxable at 18% or 24%, and residential property sales have a separate 60-day reporting deadline. Our Capital Gains Tax team handles both returns.
Savings, rent or pensions from abroad usually belong on the foreign pages of your return, with relief for overseas tax. If past years were missed, our WDF service sorts it out.
Crypto is taxed as property in the UK. We calculate gains using same-day, 30-day and Section 104 rules and complete the crypto boxes on your return. More on our crypto page.
Keep it simple: send what you have and we will tell you if anything is missing.
What if I miss the deadline? Miss 31 January and HMRC charges £100, even if no tax is due. After three months daily penalties start, and more follow at six and twelve months. New points-based penalties arrive for all Self Assessment from April 2027.
