Introduction to Marriage Tax Benefits

Introduction to Marriage Tax Benefits

Getting married or entering into a civil partnership in the UK brings a range of legal and financial changes, including several tax advantages designed to support couples. Understanding these marriage tax benefits is important for effective financial planning, as it can help you make the most of the allowances and reliefs available, reduce your overall tax liability, and ensure you’re not missing out on valuable entitlements.

Marriage and civil partnership can affect your taxes in several ways. The main areas where couples may see benefits are income tax, inheritance tax, and certain capital gains tax scenarios. For example, the government allows married couples and civil partners to transfer a portion of their personal income tax allowance to each other under specific circumstances. This is set out in the Income Tax Act 2007, Section 56, which outlines the rules for income tax treatment of married couples and civil partners.

Inheritance tax is another key area where marriage can make a significant difference. Assets passed between spouses or civil partners are generally exempt from inheritance tax, helping couples protect their estate for the future. The rules governing these exemptions are detailed in the Inheritance Tax Act 1984, which sets out the framework for how inheritance tax is assessed and collected in the UK.

These benefits are not limited to those who are married; civil partners are treated the same way under UK law, ensuring equal access to tax reliefs and exemptions. This alignment reflects the broader legal rights of married couples and civil partners, which extend beyond tax to other areas such as property, pensions, and next-of-kin status.

Whether you are planning your finances as a couple or considering how marriage or civil partnership might affect your tax position, it’s important to be aware of these rules. By understanding how income tax, inheritance tax, and other financial matters are impacted, you can take steps to maximise your entitlements and make informed decisions about your future together.

Income Tax Benefits for Married Couples

Income Tax Benefits for Married Couples

Marriage and civil partnership can bring significant income tax advantages in the UK, helping couples manage their finances more effectively. Understanding how these benefits work is important for making the most of your entitlements and reducing your overall tax liability.

How Marriage Affects Income Tax Liability

When you marry or enter into a civil partnership, your tax situation may change in several ways. While the UK tax system does not require married couples to file joint tax returns, there are specific allowances and options that can lead to tax savings. One of the main ways this happens is through the Marriage Allowance, which allows couples to transfer a portion of their personal allowance to their spouse or civil partner.

The Marriage Allowance: Eligibility and Tax Savings

The Marriage Allowance lets one partner transfer up to 10% of their personal allowance to the other, potentially reducing the recipient’s tax bill by up to £252 a year (for the 2023/24 tax year). To be eligible:

  • You must be married or in a civil partnership.
  • One partner must have income below the personal allowance threshold (currently £12,570).
  • The other partner must be a basic rate taxpayer (earning between £12,571 and £50,270).

If you meet these criteria, you can apply for the Marriage Allowance, which is set out in law under the Income Tax Act 2007, Section 56. This legal provision ensures that eligible couples can transfer part of their allowance and benefit from a reduced overall tax bill.

Example

Suppose Alex earns £10,000 per year (below the personal allowance), and Sam earns £30,000 per year (a basic rate taxpayer). Alex can transfer £1,257 of their personal allowance to Sam. As a result, Sam pays tax on £1,257 less of their income, saving up to £252 in tax for the year.

Joint Filing and Income Splitting

Unlike some countries, the UK does not have a system of joint tax returns for married couples or civil partners. Each person is taxed individually. However, Marriage Allowance provides a way to share unused personal allowance between spouses, which is the closest equivalent to income splitting in the UK.

If both partners have similar incomes above the personal allowance, the Marriage Allowance will not offer additional savings. However, if one partner earns significantly less, transferring allowance can be highly beneficial.

Child Tax Credits and Family Finances

In addition to Marriage Allowance, married couples and civil partners may be eligible for other financial support, such as Child Tax Credits. These credits are designed to help families with the cost of raising children and can be claimed alongside other marriage-related tax benefits. For more information on eligibility and how to claim, visit the official Child Tax Credits page on GOV.UK.

Combining Marriage Allowance and Child Tax Credits can significantly improve a family’s finances, especially when one partner has a lower income or if you have dependants. For a detailed breakdown of how these credits work, see our guide on Child Tax Credits.

Further Considerations

Understanding the full range of financial and legal effects of marriage is essential for effective tax planning. To learn more about the broader legal rights and responsibilities that come with marriage or civil partnership, explore our guide to marriage rights.

By making use of the Marriage Allowance and other available credits, married couples and civil partners can optimise their tax position and make the most of their combined income. If you think you may be eligible, it’s worth checking your circumstances and applying for these benefits to ensure you’re not missing out.

Inheritance Tax Benefits for Married Couples

Inheritance Tax Benefits for Married Couples

Inheritance tax (IHT) can significantly affect the value of what you leave behind, but married couples and civil partners enjoy important benefits that can reduce or even eliminate this liability. Understanding these rules is crucial for effective estate planning and ensuring your loved ones are financially protected.

How Inheritance Tax Works for Married Couples and Civil Partners

In the UK, inheritance tax is usually charged at 40% on estates valued above the nil-rate band, which is currently £325,000 per individual. However, special rules apply to married couples and civil partners, offering substantial tax advantages. If you’re legally married or in a registered civil partnership, assets left to your spouse or civil partner are generally exempt from inheritance tax, no matter the amount. This exemption applies regardless of whether you are in an opposite-sex or same-sex relationship, as detailed under the Civil Partnership Act 2004.

These rights are designed to protect partners financially after one passes away. For more on these protections, see our guide to inheritance rights for spouses.

The Nil-Rate Band and Transfer Between Spouses

The nil-rate band is the threshold below which no inheritance tax is due. When one spouse or civil partner dies and leaves their entire estate to the surviving partner, not only is the transfer tax-free, but any unused portion of their nil-rate band can be transferred to the survivor. This means that the surviving spouse or civil partner could potentially have a combined nil-rate band of up to £650,000 when they pass away, doubling the amount that can pass tax-free to beneficiaries.

For example, if John leaves his entire estate to his husband, David, no inheritance tax is due at that time. When David later dies, his estate can benefit from both his own and John’s unused nil-rate bands, potentially allowing up to £650,000 to be passed on free of IHT.

Reducing or Eliminating Inheritance Tax Liability

Marriage or civil partnership can therefore play a vital role in minimising inheritance tax. In addition to the transferable nil-rate band, there are other allowances, such as the residence nil-rate band, which may be available if you leave your home to direct descendants. By combining these allowances, many married couples and civil partners can pass on significant wealth without incurring inheritance tax.

It’s important to remember that these benefits are only available to couples who are legally married or in a registered civil partnership. Unmarried couples, even those who have been together for many years, do not receive these advantages.

The Importance of Estate Planning and Wills

To make the most of these inheritance tax benefits, proper estate planning is essential. This includes drafting a valid will and considering how assets are owned and passed on. Without a will, your estate may not be distributed according to your wishes, and your loved ones could miss out on valuable tax benefits. For practical steps and further guidance, visit our page on wills and estate planning.

The rules governing inheritance tax are set out in the Inheritance Tax Act 1984. This legislation provides the official framework for assessing and collecting inheritance tax in the UK.

Key Takeaways

  • Assets left to a spouse or civil partner are generally exempt from inheritance tax.
  • The unused nil-rate band can be transferred between spouses, potentially doubling the tax-free threshold.
  • Only legally married couples and civil partners qualify for these benefits; cohabiting partners do not.
  • Careful estate planning, including making a will, is crucial to maximise these tax advantages.

Other Tax and Financial Benefits of Marriage

Marriage and civil partnership offer a range of tax and financial advantages beyond the well-known allowances. Understanding these benefits can help couples make informed decisions to reduce their tax liabilities and strengthen their financial position.

Capital Gains Tax (CGT) Reliefs

One significant benefit for married couples and civil partners is the ability to transfer assets between each other without triggering Capital Gains Tax. Normally, selling or gifting assets like shares or property (that isn’t your main home) may lead to a CGT charge. However, transfers between spouses or civil partners are exempt, allowing couples to move assets freely and potentially take advantage of both partners’ annual CGT allowances when eventually selling those assets.

Stamp Duty Land Tax (SDLT) Considerations

When buying property together, married couples and civil partners can sometimes benefit from more favourable Stamp Duty rules. For example, if one partner already owns a property and the other does not, the couple may be able to avoid the higher rate of SDLT that usually applies to additional properties, depending on how the property is purchased and whether it will be their main home. It’s important to review the latest government guidance or consult a legal adviser for your specific situation.

Pensions: Contributions and Benefits

Marriage can have a notable impact on pensions. Spouses and civil partners may be entitled to inherit pension benefits or receive a survivor’s pension if their partner dies, which is not always the case for unmarried couples. Additionally, you may be able to boost your retirement savings by making contributions on behalf of your spouse, potentially increasing tax relief. For more details on how marriage affects your pension rights, see our guide to pension rights for spouses.

If you want to understand more about how tax relief works for pensions and the financial advantages of contributing to your spouse’s pension, MoneyHelper provides a clear overview in their guide on pension contributions and benefits.

Shared Assets and Property Ownership

Married couples and civil partners often find it easier to manage and share assets. For example, any jointly owned property or savings can be allocated in a way that maximises tax efficiency. Income from jointly owned assets can be split for tax purposes, potentially lowering your overall tax bill. For more on this topic, see our advice on sharing money and belongings with your spouse.

Government Benefits and Tax Credits

Your marital status can affect your eligibility for certain government benefits and tax credits. For instance, being married may impact means-tested benefits, such as Universal Credit, as your household income and assets are assessed jointly. In some cases, couples may qualify for higher thresholds or additional allowances, while in others, combining incomes could reduce the amount you’re entitled to receive.

Immigration and Financial Matters

Marriage also plays a key role in immigration-related financial matters. If one partner is applying for a visa or residency, being married or in a civil partnership can affect eligibility and financial requirements, such as minimum income thresholds. To learn more about the financial considerations involved, visit our section on spouse visa and immigration rights.


By fully understanding these additional tax and financial benefits, married couples and civil partners in the UK can make more informed choices about their finances, property, and long-term planning.

Planning and Managing Your Tax Benefits as a Married Couple

Planning and Managing Your Tax Benefits as a Married Couple

Making the most of marriage tax benefits starts with careful planning and regular review of your finances and legal documents. Here are some practical steps and considerations to help you and your partner maximise your entitlements and avoid common pitfalls.

Make the Most of Allowances and Reliefs

Married couples and civil partners in the UK can take advantage of several tax allowances, such as the Marriage Allowance and the ability to transfer unused personal allowances. By assessing your combined income and tax bands, you can often reduce your overall tax bill. For example, if one partner earns less than the personal allowance threshold, you may be able to transfer a portion of this allowance to the higher-earning partner, resulting in significant savings. Regularly reviewing your financial arrangements ensures you’re making full use of these benefits.

Update Legal Documents After Marriage

After getting married, it’s crucial to update your legal documents and inform relevant organisations of any changes. This includes notifying HMRC and your employer, especially if you have changed your surname. Keeping your records up to date helps prevent issues with tax codes, allowances, and National Insurance contributions. For more guidance, see our section on changing your name after marriage.

It’s also wise to review your will. Marriage can revoke an existing will unless it was made in contemplation of marriage, so creating a new will ensures your wishes are clear and your spouse is protected under inheritance tax rules. The Inheritance Tax Act 1984 sets out the framework for how inheritance tax applies to married couples, including valuable exemptions for assets passed between spouses or civil partners.

Property Ownership and Financial Arrangements

How you and your spouse own property can have significant tax implications. Joint ownership may offer advantages, such as sharing the Capital Gains Tax allowance if you sell an asset, or ensuring that property passes automatically to your partner on death. However, it’s important to consider what happens if your relationship ends. Understanding your rights around keeping your home after separation can help you make informed decisions now and avoid complications later.

If you are considering buying property together, think about whether to hold it as joint tenants or tenants in common. This affects not only inheritance but also how tax liabilities are shared. For more details on the tax and legal aspects of property division during divorce, see our guide on property considerations during divorce process.

Pensions and Financial Orders on Divorce

Pensions are often one of the largest assets in a marriage, and the way they are shared can have major tax consequences. If you separate or divorce, you may need to consider pension sharing arrangements. These allow pensions to be divided fairly, but it’s important to understand how this affects your future tax position and retirement plans.

Similarly, divorce financial orders determine how assets, income, and property are split. The tax treatment of these settlements can be complex, particularly when transferring assets or making lump-sum payments. Getting the right advice can help you avoid unexpected tax bills and ensure a fair outcome.

Seek Professional Advice for Complex Situations

While many couples can manage basic tax planning themselves, more complex situations – such as owning multiple properties, running a business, or dealing with international assets – often require specialist advice. A qualified solicitor or tax adviser can help you navigate the rules, make the most of available reliefs, and ensure your financial arrangements are robust for the future.

By staying proactive and regularly reviewing your financial and legal situation, you can ensure that you and your partner benefit fully from the tax advantages of marriage, both now and in the years to come.
