If you own a property with another person, the tax rules are different from sole ownership. Understanding how joint property ownership is taxed is essential for compliance and tax planning. This guide explains the key concepts and obligations.
For a complete overview of property tax, see our main Property owners and landlords page.
Tenants in Common vs Joint Tenants
There are two ways to own property jointly:
- Both owners have equal rights to the whole property.
- If one owner dies, the other automatically inherits the property.
- The ‘right of survivorship’ applies.
- Each owner owns a specific share of the property (e.g., 50/50, 60/40, or unequal shares).
- Each owner can sell or transfer their share independently.
- If one owner dies, their share passes to their estate, not automatically to the other owner.
How is Rental Income Taxed for Joint Owners?
For Joint Tenants
- For tax purposes, you are automatically treated as owning the property equally (50/50), even if you contributed unevenly to the purchase price.
For Tenants in Common
- You are taxed based on the actual shares you own. If you own 60%, you are taxed on 60% of the rental income.
- You can also elect to split the income differently (e.g., according to your contributions) by submitting a Form 17 to HMRC.
Form 17: Splitting Income Unequally
If you are tenants in common and you and your co-owner want to be taxed on your actual beneficial interest (rather than the default 50/50), you can submit a Form 17 to HMRC.
You can only do this if:
- You have an actual beneficial interest in the property (the shares must be unequal).
- You notify HMRC in writing (Form 17).
- The split reflects the actual ownership shares.
How is Capital Gains Tax (CGT) Treated?
For Joint Tenants
- The gain is split equally (50/50) for CGT purposes.
- Each owner can claim their Annual Exempt Amount (£3,000). See our guide: Capital Gains Tax for Landlords.
For Tenants in Common
- The gain is split according to the actual ownership shares.
- Each owner claims their Annual Exempt Amount on their share of the gain.
Reporting Requirements
Each owner must:
- Declare their share of the rental income on their own Self Assessment tax return. See our guide: Landlord Tax Return Guide.
- Pay tax on their share of the rental income at their marginal rate.
- For CGT, each owner must report their share of the gain.
Example: Joint Tenants
- Rental income: £24,000 per year.
- Ownership: Joint tenants (50/50).
- Each owner declares: £12,000.
- Each owner pays tax on £12,000 at their marginal rate.
Example: Tenants in Common
- Rental income: £24,000 per year.
- Ownership: Tenant A owns 75%, Tenant B owns 25%.
- Tenant A declares: £18,000.
- Tenant B declares: £6,000.
Transferring Property Between Joint Owners
If you transfer your share of a property to your spouse or civil partner, there is no CGT to pay at the time of the transfer (it’s treated as a disposal at ‘no gain, no loss’). However, the transferee takes over the original acquisition cost for future CGT calculations.
Stamp Duty Land Tax (SDLT)
When you buy a property jointly, you are jointly and severally liable for SDLT. If either owner is a higher-rate taxpayer (e.g., buying a second home), the higher rate applies to the whole transaction. See our guide: Buy-to-Let Tax.
