So, if you were earning £250,000 per tax year trading Forex.
You are only open to Income tax, not Capital Gains Tax.
This would be how you work out the income tax due on a £250,000 Forex related income for the tax year 2012-13
£250,000 Income - £0.00 Personal Allowance (no personal allowance as we are earning over £100,000)
- Basic Rate Tax Band:
£34,370 of the £250,000 taxed at 20% = [B]£6,874[/B]
Now we have the £250,000 - £34,370 = £215,630 which still needs taxing
- Higher Rate Tax Band:
£150,000 of the £215,630 taxed at 40% = [B]£60,000[/B]
Now we have the £215,630 - £150,000 = £65,630 which still needs taxing
- Additional Rate:
£65,630 of the remaining £65,630 taxed at 50% = [B]£32,815[/B]
So, the income tax due on a £250,000 income via Forex trading would be:
£6,874 + £60,000 + £32,815 = [B]£99,689[/B]**
Income received after tax:
£250,000 - £99,689 = [B]£150,311[/B]**
**This is an estimation and should not be used to compute any tax workings.
