Can Foster Carers Split Income Between Spouses?

“It Goes Into Our Joint Account… So Surely We Can Split It?”

That was the first thing Richard asked during our meeting.

His wife, Claire, had been an approved foster carer for several years. Every month, the fostering allowance landed in their joint bank account, helping to cover household expenses, family holidays and the day-to-day costs of looking after children.

Richard assumed the tax position was straightforward.

“We’re married,” he said. “The money belongs to both of us anyway.”

It’s a question many foster carers ask.

If you’re married or in a civil partnership, share your finances and both contribute to the household, it seems perfectly reasonable to think the fostering income can simply be divided between you.

Unfortunately, tax doesn’t always follow what feels fair.

When it comes to fostering income, HMRC is interested in who is legally entitled to receive the income, not necessarily who spends it.

That distinction can make a significant difference to how the income should be reported and whether it can be shared between spouses.

The Short Answer

Can foster carers split income between spouses?

Sometimes, but not automatically.

Whether fostering income can be shared depends on several factors, including:

• Who is approved as the foster carer.
• Whose name appears on the fostering agreement.
• Who has the legal right to receive the payments.
• Whether one or both spouses are approved foster carers.
• How the Qualifying Care Relief rules apply to your circumstances.

Many couples assume marriage alone allows them to divide the income for tax purposes. In practice, the position is usually more nuanced.

The First Question Isn’t “Who Receives the Money?”

It’s:

Who Has the Right to Earn It?

This is where many people become confused.

Imagine these two situations.

Couple A

Sarah is the approved foster carer.

The fostering service contracts only with Sarah.

Payments are made into the couple’s joint bank account.

Although both spouses help care for the child, Sarah remains the person who is contractually responsible for the fostering arrangement.

Couple B

James and Emily are both approved foster carers.

Their fostering service recognises them as a fostering household, and both play an active role within the approved arrangement.

Their circumstances may require a different tax analysis because the legal and contractual position is different.

At first glance, both households look almost identical.

Both are married.

Both care for foster children together.

Both receive fostering payments.

But the tax position may not be the same.

That’s why relying on another foster carer’s experience can sometimes lead to incorrect conclusions.

AccounTax Zone Insight:
One of the biggest misconceptions is that ownership follows the bank account.
It doesn't.
Just because fostering payments are paid into a joint account doesn't automatically mean each spouse owns half of the income for tax purposes.
HMRC generally looks beyond where the money is paid and considers who is legally entitled to receive it.

Why Marriage Doesn’t Automatically Change the Tax Position

Many parts of the UK tax system recognise married couples and civil partners.

For example, there are rules covering:

• Marriage Allowance
• Transfers of assets between spouses
• Joint ownership of property
• Inheritance Tax exemptions between spouses

Because of this, it’s understandable why some couples assume fostering income works in exactly the same way.

However, fostering income is different.

The payments arise because someone has entered into an approved fostering arrangement with a fostering service.

The starting point is therefore understanding who that arrangement belongs to.

Only then can the correct tax treatment be considered.

Does It Matter Who Signed the Fostering Agreement?

In many cases, yes.

The fostering agreement often helps establish:

• who the fostering service has approved,
• who accepts responsibility for the placement,
• who receives the fostering payments,
• and who is expected to meet the responsibilities of a foster carer.

This doesn’t necessarily answer every tax question on its own, but it is an important part of understanding the overall position.

If only one spouse is party to the arrangement, that fact is likely to be relevant when determining who is entitled to the fostering income.

A Common Misunderstanding

It’s easy to assume that because both spouses contribute equally to caring for a child, the income should automatically belong to both of them.

In reality, legal responsibility and day-to-day support aren’t always the same thing.

One partner may:

• attend meetings,
• complete training,
• communicate with the fostering agency,
• and hold the formal approval.

Meanwhile, the other partner may still provide invaluable support behind the scenes.

Both roles are important, but they don’t necessarily have the same tax consequences.

Questions Worth Asking Before You Assume the Income Can Be Shared

Before making any changes to your tax return, ask yourself:

• Who is named on the fostering agreement?
• Is one spouse approved, or are both?
• Who is legally entitled to receive the fostering payments?
• How have previous tax returns been prepared?
• Has Qualifying Care Relief already been claimed?
• Would changing the treatment be consistent with HMRC’s guidance?

These questions are often more important than deciding how you’d like the income to be divided.

AccounTax Zone Tip
If you're unsure how fostering income should be reported, avoid simply copying what another foster carer does.
Every fostering arrangement is different, and small differences in approval status or contractual arrangements can lead to different tax outcomes.

Why This Matters More Than You Might Think

Getting the tax treatment wrong isn’t always immediately obvious.

Many couples complete their tax returns in good faith, believing they’ve shared the income correctly.

The issue often only comes to light years later if:

• HMRC reviews a Self Assessment return,
• the fostering arrangement changes,
• a new accountant asks questions,
• or previous tax returns are revisited.

Taking time to understand the correct position from the outset is usually far easier than correcting mistakes later.

When Can Income Be Shared and What Does HMRC Consider?

Imagine two married couples.

Both foster children.

Both receive fostering payments.

Both complete Self Assessment tax returns every year.

Yet one couple reports all of the income in one spouse’s tax return, while the other divides it between them.

At first glance, one of them must be doing something wrong.

Not necessarily.

The answer depends on how the fostering arrangement is structured, not simply on the fact that they’re married.

This is why tax planning for foster carers is rarely a one-size-fits-all exercise.

The Most Important Question

Rather than asking: “Can we split the income?”

A better question is: “Who is entitled to the fostering income?”

That single question usually determines where the conversation starts.

HMRC isn’t interested in who pays the mortgage or who buys the weekly shopping.

Instead, the focus is on the legal and contractual position behind the fostering payments.

Only after understanding that position can the correct tax treatment be considered.

Scenario One – One Approved Foster Carer

Emma has been an approved foster carer for five years.

Her husband, Daniel, works full-time.

Although Daniel helps with school runs, attends meetings when possible and supports the children every day, the fostering service has approved Emma as the foster carer.

The agreement is in Emma’s name, and the fostering payments are made because of that approval.

In this situation, simply deciding to report half the income on Daniel’s tax return may not reflect the underlying legal position.

Scenario Two – A Joint Fostering Household

Now consider another family.

Rachel and Chris both completed the approval process.

They both undertake training.

They both attend review meetings.

Their fostering service recognises them as approved foster carers within the household.

Although they work together as a team, the tax position still depends on the precise legal and contractual arrangements rather than assumptions that everything is automatically shared.

The important lesson is this:

Two couples can appear identical on the surface while having completely different tax outcomes.

AccounTax Zone Insight:
One of the biggest risks is assuming that because both partners play an equal role in caring for the child, HMRC will automatically view the income as belonging equally to both.
Providing equal care and having equal tax entitlement are not always the same thing.

Why Qualifying Care Relief Makes Things More Interesting

Many foster carers have heard of Qualifying Care Relief (QCR), but fewer understand how it interacts with couples.

Qualifying Care Relief isn’t simply about reducing tax.

It determines how qualifying fostering income is assessed for Income Tax purposes and, in many cases, means foster carers pay little or no Income Tax on their fostering income.

However, before considering how the relief applies, it’s important to establish who is claiming it.

If the underlying tax treatment isn’t correct, the relief may also be applied incorrectly.

That’s why it is often better to determine ownership of the fostering income first and only then consider how Qualifying Care Relief operates.

Does a Joint Bank Account Change Anything?

This question comes up surprisingly often.

“The money goes into our joint account, so doesn’t that mean we each own half?”

Not necessarily.

A bank account is simply where the money is paid.

It doesn’t automatically determine who earned it or who should declare it for tax purposes.

The same principle applies in many other situations.

For example, someone might pay their salary into a joint account with their spouse.

That doesn’t mean half of their employment income suddenly belongs to the other spouse for Income Tax purposes.

The same type of thinking can apply when looking at fostering income.

AccounTax Zone Tip
Think of the bank account as the destination, not the source.
Where the money is paid doesn't automatically decide who should include it on a tax return.

Should You Change Previous Tax Returns?

Some couples discover years later that they may not have reported fostering income correctly.

Their first instinct is often: “Should we amend everything?”

The answer depends on the facts.

Before making any amendments, it’s sensible to establish:

• how the fostering arrangement operated,
• who was approved,
• how previous returns were prepared,
• whether Qualifying Care Relief was claimed,
• and whether any corrections are actually required.

Changing historic tax returns without understanding the underlying position could create new problems rather than solving old ones.

Questions We Ask Before Giving Advice

Every fostering household is different.

Before advising a couple, we’d normally want to understand questions such as:

• Who is named on the fostering agreement?
• Is one spouse approved or are both?
• Have your circumstances changed over time?
• How have previous Self Assessment returns been completed?
• Are you receiving any other taxable income?
• Is either spouse self-employed?
• Has HMRC ever queried the treatment of your fostering income?

These questions help build the complete picture before discussing the most appropriate tax treatment.

Common Mistakes Married Foster Carers Make

• Assuming marriage automatically means income can be divided: Marriage doesn’t automatically determine ownership of fostering income.
• Following advice from another foster carer: Your friend’s circumstances may be completely different from yours.
• Looking only at the bank account: Where payments are received isn’t the only factor HMRC considers.
• Forgetting to review the fostering agreement: The contractual arrangement is often central to understanding the correct tax position.
• Focusing only on tax: The tax treatment may also affect how your wider financial affairs are managed, so it’s important to consider the bigger picture.

AccounTax Zone Insight
The couples who experience the fewest problems usually aren't those with the simplest circumstances.
They're the ones who take the time to understand the rules before making assumptions.

A Simple Decision Framework

Looking Beyond Tax

While tax is often the main concern, splitting fostering income can also raise wider questions about:

• financial planning,
• pension contributions,
• mortgage applications,
• household budgeting,
• and future tax compliance.

Making the right decision isn’t simply about reducing tax, it should also reflect the reality of your fostering arrangement and stand up to scrutiny if questions are ever asked.

Real-Life Scenarios, Common Mistakes and What to Do Next

There isn’t a single rule that answers every question about fostering income and spouses.

That’s because no two fostering households are exactly alike.

Some couples have one approved foster carer.

Others are approved together.

Some have employment income alongside fostering, while others rely entirely on fostering payments.

The more complex your financial circumstances become, the more important it is to understand how the rules apply to your own situation rather than relying on general advice.

Let’s look at a few practical examples.

Scenario 1 – One Spouse Is the Approved Foster Carer

Hannah has been fostering for three years.

Her husband, Ben, works as an electrician.

The fostering agreement is in Hannah’s name and she is the only approved foster carer.

Although Ben provides invaluable support around the home and helps care for the children, his role doesn’t automatically mean half of the fostering income belongs to him for tax purposes.

Before considering any change to the tax treatment, the couple should understand who is legally entitled to the fostering payments and how HMRC views the arrangement.

Scenario 2 – Both Spouses Foster Together

Olivia and Mark completed the approval process together and are recognised by their fostering service as approved foster carers.

They jointly attend reviews, complete training and work as a fostering team.

Many people assume this automatically means the income should be split equally.

However, the correct treatment still depends on the legal and contractual arrangements between the couple and the fostering service.

Equal responsibility doesn’t automatically mean equal tax treatment.

Scenario 3 – The Tax Returns Have Always Been Completed One Way

David and Rachel have been fostering for nearly ten years.

Every tax return has been prepared in exactly the same way.

Recently, they read an online article suggesting married couples should always split fostering income.

They’re now wondering whether every previous tax return was wrong.

The answer isn’t found in an online article.

It starts by reviewing:

• how the fostering arrangement was established,
• how the income arose,
• whether the existing treatment reflects the legal position,
• and whether any amendment is actually necessary.

Sometimes the existing approach is entirely correct.

AccounTax Zone Insight
One of the biggest risks isn't making a mistake.
It's making changes because someone on social media said that's how they do it.
Tax planning should be based on legislation and your own circumstances—not someone else's experience.

What HMRC Is Likely to Expect

Although every case depends on its own facts, HMRC generally expects tax returns to reflect the genuine legal and commercial position.

That means the tax treatment should be consistent with:

• the fostering agreement,
• the approval process,
• the entitlement to the fostering payments,
• and the relevant tax legislation.

Trying to alter the tax position simply to reduce tax, without the underlying facts supporting that treatment, could create unnecessary difficulties if questions are raised later.

Warning Signs That You Should Review Your Position

You may benefit from specialist advice if any of the following apply:

• You’ve recently become married or entered a civil partnership.
• One spouse has stopped fostering while the other continues.
• Both spouses have become approved foster carers.
• Previous tax returns were prepared by different accountants.
• You have employment, rental or self-employment income alongside fostering.
• You’re unsure who should claim Qualifying Care Relief.
• HMRC has asked questions about previous tax returns.
• You’re considering changing how fostering income is reported.

These situations don’t necessarily mean something is wrong, but they are worth reviewing.

Common Myths About Splitting Fostering Income

Myth 1

“We’re married, so we can split all of our income.”

Marriage alone doesn’t automatically determine how fostering income is taxed.

Myth 2

“The money goes into a joint account, so we each own half.”

The bank account is only one part of the picture.

HMRC is more concerned with who is legally entitled to the income.

Myth 3

“If another foster carer does it, it must be correct.”

Every fostering arrangement is different.

What is appropriate for one household may not be appropriate for another.

Myth 4

“Qualifying Care Relief automatically allows income splitting.”

Qualifying Care Relief is a valuable tax relief, but it doesn’t decide who is entitled to the fostering income in the first place.

That question must be answered before considering how the relief applies.

Myth 5

“Changing the tax return is easy if we change our minds later.”

Amending tax returns without fully understanding the legal position can sometimes create more problems than it solves.

AccounTax Zone Tip
Whenever your fostering arrangements change, whether that's becoming jointly approved, changing fostering agencies or altering your household circumstances, it's worth reviewing your tax position rather than assuming the previous treatment is still correct.

A Simple Checklist Before You Submit Your Tax Return

Before completing your Self Assessment, ask yourself:

• Who is approved by the fostering service?
• Who signed the fostering agreement?
• Who is legally entitled to the fostering payments?
• Have your household circumstances changed since your last tax return?
• Have you applied Qualifying Care Relief correctly?
• Does your tax return accurately reflect the legal position?
• If you’re unsure, have you taken professional advice before submitting the return?

Taking a few minutes to answer these questions can help avoid much bigger issues later.

Final Thoughts

When it comes to fostering income, there isn’t a universal rule that applies to every married couple.

The right answer depends on the facts.

Instead of asking: “Can we split the income?”

it’s often more useful to ask: “Who is legally entitled to the income, and does our tax return accurately reflect that position?”

That’s a small change in wording, but it completely changes the conversation.

Understanding the answer before submitting your tax return can help you avoid unnecessary mistakes, reduce uncertainty and ensure your tax affairs reflect the reality of your fostering arrangement.
