Joint Tenants vs Tenants in Common: Why It Matters for Property Owners

When owning property with another person—whether a spouse, family member, or business partner—the way the property is legally held can have a significant impact on tax, succession, and long-term planning.

Many property owners overlook this, but choosing between joint tenants and tenants in common is a key decision that should be reviewed regularly.

What’s the Difference?

Joint tenants

• Each owner is treated as owning the whole property equally
• You cannot define separate shares
• On death, the property automatically passes to the surviving owner(s) under the right of survivorship

This means the property does not pass under a will, regardless of what the will says.

Tenants in common

• Each owner holds a defined share (e.g. 50/50, 70/30, 95/5)
• Shares can reflect contributions or tax planning
• On death, the share passes via the owner’s will or intestacy rules

This gives much more flexibility for both tax and estate planning.

Why This Matters for Tax

1. Capital Gains Tax (CGT)

Each owner is taxed on their share of the gain when the property is sold.

• Joint tenants → gain is typically split 50:50
• Tenants in common → gain is split according to actual ownership shares

This creates planning opportunities:

• Allocate more ownership to the spouse with unused basic rate band
• Use both individuals’ annual exemptions (£3,000 for 2025/26)

2. Income Tax on Rental Profits

Rental income is generally taxed based on beneficial ownership.

• Joint tenants → usually taxed 50:50 (for spouses, unless a declaration is made)
• Tenants in common → taxed based on the actual ownership split

This allows:

• Shifting income to a lower-rate taxpayer
• Reducing overall tax on rental profits

3. Stamp Duty Land Tax (SDLT)

Changing ownership can trigger SDLT if consideration is given, including:

• Taking on part of a mortgage

However:

• Transfers between spouses with no consideration generally do not trigger SDLT
• But mortgage transfers must always be reviewed carefully

Inheritance Tax (IHT) and Estate Planning

Ownership structure has a major impact on what happens on death.

Joint tenants

• Property automatically passes to the surviving owner
• For spouses, this is usually IHT-free due to spouse exemption
• But there is no control over where the asset goes next

Tenants in common

• Your share passes according to your will
• Can be left to:
  • Children
  • Trusts
  • Other beneficiaries

This allows:

• Better use of the nil rate band
• Protection of family wealth
• Planning around care fees or second marriages

As confirmed in the ICAEW material, the deceased’s share forms part of their estate and can be directed accordingly under a tenants in common structure

Planning Opportunities

Using tenants in common can unlock several strategies:

• Pre-sale CGT planning by adjusting ownership shares
• Income splitting to reduce higher rate tax exposure
• Estate planning to control how assets pass on death
• Protecting assets for children or future generations

However, what works for income tax may not always be optimal for CGT or IHT, so planning needs to be coordinated.

When Should You Review Ownership?

You should review how a property is held if:

• You are planning to sell
• One spouse is a higher-rate taxpayer
• Your portfolio is generating significant income
• You are doing estate planning or writing a will
• There have been changes in family or financial circumstances

Conclusion

The choice between joint tenants and tenants in common is far more than a legal formality—it is a fundamental part of tax and estate planning for property owners.

A simple change in ownership structure can:

• Reduce tax liabilities
• Improve flexibility
• Provide better long-term protection for your assets
