Walking down the aisle to say your nuptials, through marriage or a civil partnership, is one of life’s pivotal moments.
 
As you embark on your new chapter together, you may think about the financial benefits you could reap from making your partnership official.

Here are three ways you could prosper together.

1. Enjoy potential Income Tax savings

The Marriage Allowance could reduce the Income Tax you pay.

Depending on your earnings, the tax rules allow you to transfer all or some of your annual Personal Allowance.
 
Your spouse or civil partner may be able to transfer part of their Personal Allowance to you if:

• Their income is less than £12,570 (2025/2026), meaning they do not pay Income Tax.
• You pay basic-rate tax – meaning your income is between £12,571 and £50,270 in 2025/2026. Your spouse or partner cannot transfer any of their Personal Allowance if you’re a higher- or additional-rate taxpayer.

The Marriage Allowance could help you to reduce your tax bill by up to £252 in 2025/2026. If you meet the criteria, you may be able to backdate your claim by up to four years.

Though this is a super-easy way to save on tax, many couples fail to take advantage. Indeed, MoneyWeek reports that an estimated 2.1 million eligible couples are missing out on potential savings [1]. 

The government website has a handy Marriage Allowance calculator to help you find out how much you could save.

2. Reduce your Capital Gains Tax bill

The Annual Exempt Amount for Capital Gains Tax (CGT) is £3,000 (2025/26) – a charge only becomes due if profits exceed this amount.
 
In 2025/26, you can team up and make profits of £6,000 in a single tax year before facing a charge.

CGT is usually payable on profits from selling certain assets, including: 

• Shares held outside of a tax-efficient wrapper, such as an ISA or pension
• Personal possessions worth more than £6,000 (excluding your car) 
  •    Property that’s not your main home.

CGT rates range between 18% and 32% (2025/26). The amount you’ll be charged will depend on your marginal rate of Income Tax and the asset you sell.

Tax rules can be complex, so if in doubt, please get in touch. Your Titan Wealth Planner can help ensure you’re making the most of all your tax allowances.
 
3. Help your family reduce Inheritance Tax

Being married often makes Inheritance Tax (IHT) planning easier.

This is because IHT rules for married couples or civil partners mean that:

• Your spouse or civil partner can usually inherit your entire estate without paying any IHT.
• You can pass on any unused “nil-rate band” – £325,000 in 2025/2026 – to your spouse or civil partner.

If you pass your main home to your children or grandchildren, you may also benefit from the “residence nil-rate band” – £175,000 for each of you. And, like the nil-rate band, you can pass on any unused allowance to your spouse.

All this to say, as a couple, you can potentially pass on up to £1 million without IHT. 

Every major life event could affect your financial plan

Marriage is just one momentous occasion that may result in you needing to review your financial plan.

Whether you’re getting married, making a career change, celebrating the birth of a child, or reacting to a life change forced upon you – every major life event carries a significant financial impact, but also an opportunity.
