Who this is for: For founders who hold or are considering holding investment property and want to understand the full tax comparison before making a decision.
The question of whether to hold investment property personally or through a company is one of the most common questions founders ask. The answer depends on three factors: the rental yield, the expected capital gain, and the investment horizon.
The rental income comparison
Rental income held personally is taxed at the marginal income tax rate: 20%, 40%, or 45% depending on total income. For a founder paying 45% income tax, £100,000 of rental income leaves £55,000 after tax.
Rental income held in a company is taxed at 25% corporation tax. £100,000 of rental income leaves £75,000 after corporation tax. The annual saving is £20,000 per £100,000 of rental income.
Over ten years, the compounding advantage of retaining rental income inside a company at 25% versus extracting it personally at 45% is significant.
The capital gain comparison
When a property is sold personally, the gain is taxed at 18% (basic rate) or 24% (higher rate) CGT, after the annual exempt amount. For a founder paying higher rate CGT, the effective rate on a property gain is 24%.
When a property is sold by a company, the gain is taxed at 25% corporation tax. The after-tax proceeds are then subject to dividend tax (33.75% to 39.35%) when extracted personally. The combined rate on a property gain extracted from a company is approximately 54%.
The comparison
| Personal ownership | Company ownership | |
|---|---|---|
| Rental income tax rate | 45% | 25% CT |
| CGT on disposal | 24% | ~54% (CT + dividend tax) |
| IHT on death | 40% (no BPR) | 40% on shares (no BPR for investment co) |
| Best for | Short-term hold, high gain | Long-term hold, high yield |
The company is better for rental income. The personal name is better for capital gains. The right structure depends on whether you plan to sell or hold.
The holding company solution
For founders who want both the rental income efficiency and the capital gain efficiency, a holding company structure can be designed to hold the property company, with the property company paying dividends to the holding company free of corporation tax (under the dividend exemption). The holding company retains the capital at 25% corporation tax. When the property is eventually sold, the proceeds remain inside the structure rather than being extracted personally.
What This Looks Like for Your Numbers

The Property Architecture
The personal versus company property question is a Stability-layer question. Standard accountancy advice addresses it correctly. It is also the ceiling of what standard advice addresses. The Growth layer (a dedicated property holding company within a group structure) changes the question entirely. Property held inside a group can be funded by intercompany loans, generating interest deductions at the trading company level and compounding capital at the holding company level without triggering personal tax on the rental income.
The Expansion layer is the constitutional architecture that governs how property assets interact with the rest of the group, how they are funded, how income flows, how they are protected from trading risk, and how they transfer to the next generation without triggering the CGT and IHT events that an unplanned transfer creates.
