Can I Move Assets Between Spouses to Save Tax

At Towerstone, we provide specialist capital gains accountancy services for married couples and civil partners. We have written this article to explain how transfers between spouses can reduce tax, helping you make informed decisions.

One of the most effective tax planning strategies in the UK is moving assets between spouses. The tax system is designed to treat married couples and civil partners more favourably than individuals which means you can often reduce Income Tax, Capital Gains Tax and even Inheritance Tax by transferring assets to your spouse. In my opinion this is one of the most underused tax opportunities because many people assume transferring assets will trigger tax charges when in reality the rules are surprisingly generous.

This guide explains when you can move assets between spouses, how the transfers work, what taxes you can save, which assets can be moved, what paperwork is involved and the pitfalls to avoid. I will also include real world examples because they make the rules much easier to understand.

By the end you will understand exactly how spousal transfers work and how they can help you save significant amounts of tax legally and efficiently.

Understanding the Special Tax Rules for Spouses

The UK tax system treats married couples and civil partners as two individuals although it allows certain benefits when assets move between them. These benefits do not apply to unmarried couples no matter how long they have lived together.

The most valuable rule is this:

Transfers between spouses are usually tax free.

This applies to:

Capital Gains Tax
Income Tax shifting opportunities
Inheritance Tax

The idea behind the rule is that married couples are treated as a single economic unit. In my opinion this is one of the most powerful planning tools available because it lets you restructure ownership to reduce your family’s tax bill as a whole.

Can I Move Assets Between Spouses Without Paying Tax

Yes. You can transfer assets between spouses with:

No Capital Gains Tax
No Stamp Duty in most cases
No Income Tax on the transfer
No Inheritance Tax at the time of transfer

The key phrase HMRC uses is:

Transfers between spouses occur on a “no gain, no loss” basis.

This means the receiving spouse takes on the original base cost of the asset and no tax charge arises on the transfer.

Important reminder:

This rule applies only if you are married or in a civil partnership. It does not apply to partners living together without formal status.

Why Move Assets Between Spouses

Transferring assets is legal tax planning. You may do it for several reasons:

1. To use the lower income spouse’s tax band

If one spouse pays higher rate tax and the other pays basic rate you can transfer income producing assets to the lower earning spouse so the income is taxed at a lower rate.

For example:
Rent
Dividends
Savings interest
Premium Bond winnings are tax free anyway

This reduces your combined tax bill.

2. To use both personal allowances

Each spouse has a:

Personal allowance
Dividend allowance
Savings allowance
CGT annual exemption

Using two sets of allowances can save a lot of tax.

3. To reduce Capital Gains Tax

If one spouse has used their CGT allowance but the other has not you can transfer shares or other assets to them before selling. You then use their CGT exemption to reduce tax.

4. To reduce Income Tax on rental income

If one spouse pays higher rate tax and the rental income is significant you can transfer part or all of the property to the lower earning spouse.

5. To save Inheritance Tax long term

Gifts between spouses are exempt from IHT. Moving assets into the name of the spouse with better long term planning needs can be beneficial.

In my opinion income and CGT planning are the biggest reasons couples transfer assets because the savings can be substantial.

What Types of Assets Can Be Transferred

You can transfer almost any personal asset to your spouse tax free including:

Property
Shares
ISAs cannot be transferred but assets inside them can pass tax free on death
Business assets
Rental property
Crypto
Investments
Cars
Cash
Premium Bonds
Furnished holiday lets
Bank accounts
Personal belongings

The no gain, no loss rule applies to nearly all capital assets.

Assets that cannot be transferred freely:

Your ISA (although your spouse can inherit it on death)
Pensions
Company shares where restrictions apply
Trust interests

Everything else can usually be transferred with ease.

Capital Gains Tax: Why Spousal Transfers Are Powerful

When transferring an asset to your spouse:

No CGT is triggered
The spouse takes on your original base cost

This means you can double your annual CGT exemptions when selling investments.

Example:

You bought shares for £10,000
They are now worth £40,000
Gain = £30,000

If you sell alone:
You have one CGT allowance
Tax due on the remaining gain

If you transfer half the shares to your spouse:
You use two CGT allowances
You may reduce or eliminate the tax entirely

In my opinion this is one of the most widely used techniques among investors who want to sell shares tax efficiently.

Income Tax: Moving Assets to the Lower Earning Spouse

Income producing assets can be transferred to a spouse to reduce tax.

Assets that produce taxable income:

Rental property
Shares paying dividends
Savings
Business income from jointly owned businesses

Example:

One spouse earns £30,000
The other earns £95,000

If rental income is held by the higher earner they pay 40 percent or even 45 percent.
If transferred to the lower earner the rate may drop to 20 percent.

This can cut your family tax bill significantly.

Joint ownership of rental property

You can change the ownership percentage through:

A deed of trust
A Form 17 declaration

This allows you to shift rental income to the spouse in the lower tax band.

Stamp Duty: Do You Pay It When Transferring Property to a Spouse

Usually no although there are exceptions.

You do not pay Stamp Duty if:

No mortgage is being transferred
The transfer is a gift

You may pay Stamp Duty if:

There is an outstanding mortgage
The spouse being added takes on part of the mortgage
The transferred amount exceeds the SDLT threshold

Example:

£200,000 mortgage
You transfer half the home to your spouse
Your spouse “takes on” £100,000 of mortgage
SDLT may apply on the £100,000

This is often overlooked. In my opinion it is one of the biggest pitfalls couples face when transferring property.

Inheritance Tax: Spousal Transfers Are Exempt

You can move assets between spouses at any time without triggering IHT.

This is particularly important when:

One spouse has significant wealth
The other spouse has unused allowances
You want to rebalance ownership for estate planning

Spousal transfers allow married couples to use both nil rate bands effectively.

When Spousal Transfers Are Not Allowed

Transfers do not qualify for the no gain, no loss rule if:

You are separated permanently
You are not legally married or in a civil partnership
You are divorced
You transfer after the tax year of separation

Couples must be officially together in the same tax year for the rule to apply.

In my opinion many couples misunderstand the “year of separation” rule which can create unexpected CGT bills.

Does HMRC Consider It Tax Avoidance

No. Transferring assets between spouses for tax planning is legal and explicitly supported in legislation. HMRC only challenges arrangements that:

Include artificial steps
Involve non commercial structures
Attempt to disguise the true owner
Are designed to exploit avoidance loopholes

Simple transfers between spouses are normal tax planning.

How to Transfer Assets to Your Spouse Legally

The process depends on the asset:

Cash

Simple bank transfer
No tax implications

Shares

Your investment platform can perform an internal transfer
Often takes minutes

Property

Requires conveyancing
Possible SDLT considerations
A deed of trust if changing ownership percentages

Business assets

May require accountant advice
Company shares may need shareholder approval

In my opinion transferring shares or cash is the simplest and most tax efficient first step for most couples.

Real World Examples

Example 1: Dividends

You hold company shares producing £8,000 of dividends
You are a higher rate taxpayer
Your spouse is a basic rate taxpayer

Transfer shares to your spouse
Dividend tax drops from 33.75 percent to 8.75 percent
Saving over £2,000

Example 2: Rental property

Rental income £10,000 per year
Your spouse earns low income

Transfer property to spouse
Income taxed at 20 percent instead of 40 percent
Saving £2,000 per year

Example 3: Selling shares

Gain £20,000
One spouse uses their CGT exemption
Transfer half to the other spouse
Use two exemptions
No CGT due

Example 4: Savings interest

Savings interest £5,000
One spouse has no income
Savings taxed at 0 percent using their allowances

Transfer savings account
No tax payable

Common Mistakes to Avoid

Transferring assets when separated
Ignoring SDLT when a mortgage is involved
Failing to document the transfer properly
Assuming transfers apply to ISAs
Not using a deed of trust for property income
Ignoring how transfers affect wills and inheritance planning
Not updating land registry records
Rushing transfers without legal oversight

Conclusion

You can move assets between spouses to save tax and the tax rules are extremely favourable. Transfers between spouses are usually free of Capital Gains Tax, Income Tax and Inheritance Tax. This allows you to shift income producing assets, investment assets and property ownership so the lower earning spouse uses their allowances and tax bands fully. It is one of the most powerful and underused tax planning tools available to married couples.

In my opinion every couple with investments, rental property or significant savings should review ownership regularly. Even small changes can lead to large tax savings especially when it comes to income shifting and Capital Gains Tax planning.
