Transferring Rental Income to Wife via Declaration of Trust

The UK tax system is progressive, which implies that the higher earner pays a larger percentage in tax. If one spouse is a higher or additional rate taxpayer (40% or 45%) and the other is a basic rate taxpayer (20%) or has no income, moving rental income across can dramatically reduce your tax bill.

Each individual in the UK has a tax-free personal allowance (currently £12,570). If your spouse is not using theirs (e.g. they are not working or are retired), transferring rental income allows you to utilise this unused allowance.

Without this, their allowance is wasted while you pay higher tax unnecessarily.

For Example

• You: £12,000 rental income, taxed at 40%= Tax £4,800
• Spouse: £0 income, Personal allowance= £12,570 tax-free

If you transfer 100% of the rental income to your spouse, the entire £12,000 could be tax-free, or taxed at just 20% saving up to £4,800.

Even if your spouse has some income, their earnings might still fall within the basic rate band. You can transfer rental income up to the basic rate threshold (£50,270 for 2024/25) to keep them taxed at 20%, avoiding the 40% rate that you might pay otherwise.

If a married couple or civil partners jointly own a property, HMRC assumes the income is shared equally (50:50) even if the actual beneficial ownership is different.

So, even if you and your spouse have agreed between yourselves that one partner get 90% of the income, HMRC will still tax each of you on 50% unless you formally notify them otherwise.

To override the 50:50 rule, you must:

• Establish an alternative beneficial ownership split through a declaration of trust
• Submit Form 17 to HMRC within 60 days of signing the declaration of trust.

Joint Tenancy 

When two or more people purchase a property together with equal interest in the property and equal rights, this is referred to as joint tenancy. Perhaps the most common form of joint tenancy ownership is that of a married couple. A general rule of thumb for identifying a joint tenancy is what happens on death: when one joint owner passes away, their share of the property automatically passes to the surviving co-owner.

Tenancy in Common

If multiple people hold title under tenancy in common, this means that each individual can choose to sell their ownership interests in the property at any time. Unlike with joint tenancy, a tenancy in common agreement allows for multiple owners to own different percentages of the entire property. Unlike joint tenancy, a property held under tenancy in common does not automatically pass to the surviving co-owner upon death. Instead, the deceased's share is inherited by the person named in their will.

If a property is legally owned by just one spouse or civil partner, that person is legally entitled to 100% of the rental income and is therefore solely responsible for reporting and paying tax on the full amount.

However, it is possible to transfer a share of the beneficial interest in the property to your spouse using a declaration of trust. Once the beneficial interest is transferred, your spouse must declare their share of rental income on their own Self-Assessment tax return from that date, and the original owner must reduce their reported share accordingly.

For HMRC to accept the income allocation based on beneficial ownership, the declaration must:

• Reflect the true economic reality of ownership
• Be executed before the change in income allocation takes effect
• Be accompanied by Form 17 and retained for records
• Not be backdated under any circumstances

Failing to meet these requirements may result in HMRC ignoring the transfer and taxing the legal owners on the full amount.

The first legal document is to draft a Deed of Assignment with a solicitor. This step formalises who receives the income benefit, regardless of the legal ownership registered with the Land Registry.

Once the beneficial interest has been legally assigned, the next step often missed is submitting Form 17 to HMRC. Form 17 notifies HMRC that you are declaring property income in accordance with the actual beneficial ownership, rather than the default 50/50 split.

A Form 17 declaration is only valid if the property is held as tenants in common, where each party has a defined share of the beneficial interest. However, many married couples own buy-to-let property as joint tenants, which means they both own the whole property together and cannot hold unequal shares.

To declare unequal ownership for tax purposes, you must first sever the joint tenancy and convert it to a tenancy in common.

Even if you are the sole legal owner of a buy-to-let property, it is still possible to share rental income with your spouse by adding them to the legal title through a transfer of equity. If the property is mortgaged, you will generally need to obtain your mortgage lender’s consent before proceeding.

Additionally, if there is an outstanding mortgage, transferring a share of the property may result in Stamp Duty Land Tax (SDLT). This is because HMRC treats the transferred share of mortgage debt as consideration, and SDLT may be payable of that amount exceeds the relevant threshold SDLT may be payable if that amount exceeds £125,000. If the consideration is below £125,000 but above £40,000, a nil SDLT return will be payable even if the SDLT return is not filed.

It is also highly advisable to consult your mortgage lender in advance, as changes to the legal ownership or mortgage deed usually require their formal approval. Once your spouse is added to the title, you can then execute a deed of trust and submit Form 17 to HMRC to reflect the new beneficial ownership split for tax purposes.

This is usually the most expensive method. In this method, the current owner needs to remove themselves fully from the title of the property and their spouse becomes the new sole owner. This can trigger Capital Gains Tax (CGT), Stamp Duty Land Tax (SDLT) and additional legal and conveyancing costs.

Because of these additional tax and legal implications, this route is typically not recommended unless part of a larger financial strategy, such as estate planning or asset equalisation in divorce proceedings.

When you dispose of any property that is not your primary residence, you owe Capital Gains Tax. However, when you dispose your rental property to your spouse, the rules for CGT differ.

Under the Taxation of Chargeable Gains Act 1992,if a husband and wife (or civil partners) are living together and one of them gives or transfers an asset, such as a share of a rental property to the other, Capital Gains Tax (CGT) is not triggered at the time of the transfer. The law treats the asset as if it were transferred at the original purchase price, so there is no gain and loss for tax purposes.

In simple terms, this means that spouses can move assets between each other without paying CGT immediately, as long as they are genuinely living together.

When you decide to split rental income for tax purposes, you can trigger the basic rate of SDLT. This can happen if the spouse takes on a share of a mortgage or pays cash for their share of the property and the total consideration exceeds the SDLT threshold.

The table below shows the basic rate of SDLT. Therefore, it is important to understand how to transfer rental income to spouse.

When the transfer consideration of a second home is more than £40,000 then 5% additional rate of SDLT applies. Any money changing hands, or a mortgage share taken can be the consideration.

However, the provisions for the higher rates do not apply on the transfers between spouses or civil partners even if the recipient already owns a property.

HMRC states “For transfers on and after 22 November 2017, the higher rate rules disregard transactions solely involving the transfer of interests between spouses or civil partners while they are treated as living together on the date of purchase.”
