Self-Assessment Tax Return London

Self-Assessment Tax Return London

Self-Assessment Tax Return Specialists for Individuals, Landlords & Business Owners Across London

Why London Residents Need a Specialist for Their Self-Assessment Tax Return

London is financially diverse. Most individuals here earn from more than one source, which significantly increases tax complexity.

We help clients who have:

Salaried income + rental income
Self-employment + dividends
Foreign income + UK income
Capital gains + crypto trading
Airbnb or short-let properties
Director salaries + dividends
Multiple businesses or side hustles

And because HMRC is now using advanced data analytics to match income from banks, property portals, and digital platforms…

Errors are easier for HMRC to detect, making a specialist accountant more important than ever.

Who Must File a Self-Assessment Tax Return?

You must file a Self-Assessment return if ANY of these apply:

✔ You’re Self-Employed

Over £1,000 trading income.

✔ You’re a Landlord

Rental income from UK or overseas property.

✔ You’re a Company Director or Shareholder

Dividends, director’s loans, benefits in kind.

✔ You Earn Over £100,000

Personal allowance reduces—complex calculations needed.

✔ You Have Investment or Crypto Income

Shares, crypto gains, dividends, interest, buy-to-let disposals.

✔ You Receive Foreign Income

Salary, dividends, rental income, remittances.

✔ You Work in the Platform/Gig Economy

Uber, Deliveroo, Airbnb, Etsy, TikTok, YouTube, OnlyFans.

✔ You’re in a Partnership or LLP

Partners always file returns.

If you’re unsure whether you need to file, ask us. Most HMRC penalties come from people who didn’t realise they were required to register.
