Reclaiming GST on subdivision

This is something you would need specific legal advice on. It could be individual, company or trustee depending on the circumstances.

Ownership entity won’t change the GST outcome either. Certainly GST can apply to the sale of vacant land, especially if you subdivide and sell as you will be conducting an enterprise. Have a look into the margin scheme to reduce any GST

I don’t know anything about the UK

There is no GST difference between ownership entities – in this situation, but there are a lot of other tax and non tax differences.

It could be anything depending on the circumstances. It will depend on a lot of thing – ability to claim the main residence exemption, land tax, intention with the front property, stamp duty laws, asset protection, estate planning etc etc

Once you determine which legal owner then you have to work out how to structure the structure. If it a company acting as trustee of a discretionary trust, then how to you fund the deposit, how about the remainder, who should be shareholder, director, terms of the trust, should the trustee be excluded as a beneficiary, should there be different capital and income beneficiaires, should default beneficiaries be included, if so what about the asset protecton issues etc

You need specific legal and tax advice.
