You already run a successful trading company, and now you want a holding company sitting above it, perhaps to protect profits, ring-fence assets, or get ready for a future sale. The obvious-sounding move, "just sell my company to a new one", would trigger a Capital Gains Tax (CGT) bill on the whole value of your business. That is exactly what you want to avoid.
The good news is there's a well-trodden route that gets you the structure you want without a tax bill on the way in: a share-for-share exchange. It's the standard, tax-efficient way we insert a holding company above an existing trading company, and it's something we set up for owner-managed businesses regularly. This guide explains what the exchange is, why it works without triggering CGT, the stamp duty position, and the practical steps. For the bigger picture of why you'd build a group at all, start with our complete group structures guide.
A share-for-share exchange is simple to picture. You incorporate a brand-new company, the holding company (HoldCo), and then you swap your shares in the existing trading company (TradeCo) for new shares in HoldCo. In exchange for handing your TradeCo shares to HoldCo, HoldCo issues shares in itself to you.
After the exchange, the ownership picture has flipped neatly: you now own HoldCo, and HoldCo owns 100% of TradeCo. You haven't sold anything for cash, you haven't taken money out, and you still ultimately own the same underlying business, you've just added a layer above it.
