Investing in a Hargreaves Lansdown SIPP via Your Limited Company (US Stocks)
This blog covers how it works, the real costs you’ll face, and actionable tips to save money—especially if your portfolio is around £100,000, mostly in a few large US stock positions.
How Employer Contributions Work via Your Limited Company
- Your limited company makes employer contributions directly into your personal HL SIPP.
- These contributions are tax deductible, reducing your company’s Corporation Tax bill by roughly 19–25%.
- The money flows directly from company retained profits → HL SIPP, allowing you to build your pension pot efficiently.
- Inside the SIPP, you can invest in a wide range of assets, including UK and US individual stocks, ETFs, and funds.
The Real Costs of a £100k US Stock Portfolio on HL SIPP
| Charge Type | Cost Estimate | Notes |
|---|---|---|
| Platform Fee | £200/year (0.45%, capped) | Fixed annual fee, capped for shares & ETFs |
| Dealing Fee | £11.95 per trade (£5.95 if frequent trader) | Applies to each stock buy/sell |
| FX Fee on US Stocks | 0.25% for trades over £20k | For £100k trade, expect ~£250 FX cost |
| Dividend Reinvestment | £1 per reinvestment | Minimal impact with few stocks; manual reinvestment preferred |
Important note on FX fees:
HL’s FX fee drops to 0.25% for trades over £20,000, meaning your £100k US stock purchases incur a ~£250 FX charge instead of the 1% often assumed. This is a big saving if you invest in larger lumps and this is why you should delay investing in SIPP pensions until you have the capital else its all going to be eaten in fees.
