Prop Firm Tax UK Guide: How HMRC Treats Funded Trader Income
If you're a UK funded trader, your prop firm payouts are taxable income. Here's how to handle them cleanly with HMRC.
UK funded traders have asked us this dozens of times: how do I report prop firm income? The short answer is self-employment income — but the structure matters.
You're a Service Provider, Not an Investor
Prop firm payouts are not capital gains. You don't own the capital you trade. HMRC treats your share as self-employed trading income.
Trading Allowance
Your first £1,000 of trading income each tax year is tax-free under the trading allowance. Above that, register as self-employed and file a Self Assessment.
Expenses You Can Claim
- Audit fees paid to the prop firm (until refunded)
- Trading platform subscriptions
- Charting tools (TradingView etc.)
- Home-office portion (light/heat)
- VPS rental for EAs
When To Set Up A Limited Company
Most traders earning above £50K/year benefit from a Ltd structure due to corporation tax + dividend treatment. Speak to an accountant before you incorporate.
