The Property Tax Advantages of Being Married

Marriage comes with financial benefits, including several tax advantages related to property ownership. Whether you are buying, selling, or transferring assets, married couples and civil partners can access tax reliefs that unmarried couples or single individuals cannot.

This guide explores the key property tax benefits of being married and how to optimize your tax position.

1. Capital Gains Tax (CGT) – Tax-Free Transfers Between Spouses

One of the most significant tax benefits of marriage is that spouses and civil partners can transfer property between each other without triggering CGT.

Common mistake: If an unmarried couple transfers property between them, the transfer is taxed as if it were sold at market value, leading to a CGT liability.

Married advantage: Transfers between spouses are at “no gain, no loss,” meaning the receiving spouse inherits the original purchase price and there is no immediate CGT charge.

2. Splitting Ownership to Reduce CGT on Sale

Since April 2024, the annual CGT exemption is only £3,000 per person. However, married couples can double this exemption to £6,000 by jointly owning property.

Example:

  • John owns a rental property alone and sells it, making a £20,000 gain. His CGT exemption is just £3,000, meaning £17,000 is taxable.
  • If John had transferred 50 percent of the property to his wife before selling, both could use their £3,000 exemptions, reducing the taxable gain to £14,000 and saving £600 in tax at 20 percent CGT.

Married advantage: Transferring part-ownership before selling allows couples to use both exemptions and lower the CGT bill.

3. Inheritance Tax (IHT) – Tax-Free Transfers and Double Allowances

Inheritance tax is a major concern when passing on property. The tax-free threshold (nil rate band) for IHT is £325,000 per person.

Common mistake: Unmarried partners pay 40 percent IHT on any inheritance over £325,000.

Married advantage:

  • Spouses inherit tax-free, meaning there is no IHT on assets left to a surviving spouse.
  • The unused allowance transfers to the surviving spouse, effectively doubling the IHT-free allowance to £650,000.
  • If the estate includes a main residence, couples can also use the Residence Nil Rate Band (£175,000 each), increasing their combined IHT-free threshold to £1 million.

Example:

  • An unmarried couple with an estate worth £800,000 faces an IHT bill of £190,000.
  • A married couple can pass the estate tax-free to the surviving spouse, and when passed to children later, up to £1 million can be tax-free.

4. Stamp Duty Land Tax (SDLT) – No SDLT on Spousal Transfers

If you transfer property to your spouse, no Stamp Duty Land Tax (SDLT) is payable, unless there is a mortgage balance over £250,000.

Common mistake: If an unmarried couple transfers property ownership, the recipient pays SDLT on the market value.

Married advantage: Spouses can transfer property ownership without SDLT, allowing them to strategically split assets for tax efficiency.

5. Rental Income – Shifting Tax Burden to a Lower-Earning Spouse

Rental income from property is taxable based on ownership share. If one spouse earns significantly less, shifting rental income to them can lower the tax rate.

Common mistake: Unmarried couples must be joint owners to split rental income. Married couples can adjust ownership ratios freely.

Married advantage:

  • Spouses can change property ownership shares (e.g., 90/10 split) to allocate more rental income to the lower-taxed spouse.
  • If one spouse is below the personal tax-free allowance (£12,570), they can receive rental income tax-free.

Example:

  • Emily earns £70,000 (40 percent tax rate), and her husband Alex earns £15,000 (20 percent tax rate).
  • If Emily owns a rental property generating £10,000 in income, she pays £4,000 tax at 40 percent.
  • If she transfers 90 percent ownership to Alex, he only pays £2,000 tax at 20 percent, saving £2,000.

6. First-Time Buyer Stamp Duty Relief – Marrying a First-Time Buyer Can Cost You

If you are a first-time buyer, you get SDLT relief on properties up to £425,000.

Common mistake: If a first-time buyer marries someone who already owns property, they lose first-time buyer status and must pay full SDLT rates.

Married advantage: If both partners have not owned property, they can buy a home together and claim full first-time buyer relief.

7. Avoiding the 3 Percent Additional Property SDLT Surcharge

If you already own a home and buy another, a 3 percent SDLT surcharge applies. However, if one spouse does not own a property, the couple can buy in their name and avoid the surcharge.

Example:

  • Paul owns a house and wants to buy a £300,000 buy-to-let. If bought in his name, he pays 3 percent extra SDLT (£9,000).
  • If his wife does not own property, she can buy in her name and avoid the surcharge, saving £9,000.

Married advantage: If one spouse does not own a property, they can buy an investment property in their name and avoid the 3 percent SDLT surcharge.

Final Thoughts – Why Being Married Is a Tax Advantage

Married couples and civil partners can save thousands by structuring property ownership efficiently.

  • Capital Gains Tax: Transfers between spouses are tax-free, allowing for CGT exemption planning.
  • Inheritance Tax: Assets pass to spouses tax-free, and allowances double to £650,000 or more.
  • Stamp Duty: No SDLT on transfers between spouses, and strategic purchases can avoid the 3 percent surcharge.
  • Rental Income Tax Planning: Adjusting ownership splits reduces tax on rental income.
  • First-Time Buyer Relief: If both spouses are first-time buyers, they get SDLT discounts.
