The Complete Guide To Foster Carer Tax Relief 

For anyone – not just foster parents – the word “tax” is readily associated with confusion, stress and panic. Every year, foster parents across the UK wonder: 

“Do I need to file a tax return?” 
“Is my fostering income taxable?” 
“What on Earth is Qualifying Care Relief?” 

Foster carers are often entitled to generous tax relief, income exemptions and a unique calculation method that simplifies the self-assessment process. 

Whether you’re new to fostering or have been doing it for years, understanding how Qualifying Care Relief works and how it applies to your circumstances can save you time, stress – and potentially a tidy sum of money. 

In this guide, we’ll walk you through: 

• What foster carers need to know about tax and income reporting. 

• How to calculate your taxable income (with simple examples). 

• What you can claim, deduct or ignore. 

• Where to get trusted help if you’re still unsure. 

What is Qualifying Care Relief for fostering? 

If you remember just one phrase from this blog, make it this one: Qualifying Care Relief. 

It’s a tax relief scheme created by HMRC specifically for foster carers and others who provide care in their home. Its aim is to make tax simpler, fairer and more manageable for carers across the UK. 

Who can claim Qualifying Care Relief? 

You’re eligible if you provide one of the following types of care: 

• Foster care (through a local authority or fostering agency). 

• Shared Lives care (adult placement). 

• Staying Put care. 

• Parent and child arrangements. 

At Mosaic Foster Care, our foster parents typically qualify under the foster care category and that means they can use this scheme to calculate their taxable fostering income in a way that’s tailored to the realities of care work. 

Why does this relief exist? 

That’s simple – caring isn’t a typical job. Your home is your workplace, your hours are unpredictable and the line between personal and professional expenses is blurred. The scheme recognises that, and gives foster parents: 

• A fixed tax exemption threshold. 

• A simplified method to calculate taxable income. 

• The chance to often pay no tax at all on fostering income. 

In short: Qualifying Care Relief can dramatically reduce your tax bill – or eliminate it altogether. 

How Foster Parent Income Is Calculated 

Now we know what Qualifying Care Relief is, let’s break down how it works in practice. HMRC offers two ways to calculate your taxable income as a foster parent and you get to choose the one that works best for you. 

Option 1: The Simplified Method (Qualifying Amount) 

This is the method most foster carers use. It involves two parts: 

1. A fixed tax exemption of £10,000 per household (regardless of the number of children). 

2. A weekly tax relief allowance for each child in placement: 

• £200 per week for children under 11 

• £250 per week for children 11 or older 

You add both together and that becomes your Qualifying Amount. If your total fostering income is below that figure, you don’t pay any tax on it. 

Example: 

Let’s say you foster: 

• One child aged 12 for the full tax year (52 weeks) 

Your calculation would be: 

• £10,000 (fixed exemption) 

• (£250 × 52 weeks) = £13,000 

• Total Qualifying Amount = £23,000 

If you received £23,000 or less in fostering payments, you won’t pay any tax on that income and you don’t need to list it as taxable e.g. If your fostering income exceeds the QCR threshold, the excess amount is treated as taxable profit. You can then use your personal allowance to offset this taxable profit. So, if you have no other income, you can still earn up to £12,570 tax-free on top of your QCR threshold. 

Option 2: The Profit Method 

If your income is above the Qualifying Amount, or if you have unusually high expenses, you may choose to be taxed on your actual profit instead. 

This involves: 

• Declaring your total fostering income. 

• Deducting allowable expenses (we’ll cover those in the next section). 

• Paying tax on the remainder. 

Most carers don’t need to use this method but it can be beneficial in specific cases. 

Is Foster Carer Income Taxable? What About National Insurance? 

So far, you’ve learned that most foster carers don’t pay tax on their income, thanks to Qualifying Care Relief. But what if your fostering income exceeds the threshold? Or do you choose the profit method? 

Let’s tackle tax and National Insurance separately. 

Foster care and tax: When is it taxable? 

Your fostering income only becomes taxable if it exceeds your Qualifying Amount (as we calculated in the last section). If that happens, you’ll pay tax on the difference, just like any other self-employed income. 

You’ll need to: 

• Register with HMRC as self-employed. 

• Complete a Self-Assessment tax return (usually online). 

• Include your fostering income and method used (simplified or profit). 

Even if you don’t owe tax, you must still register and complete a return if you receive fostering payments – that’s a legal requirement. 

What about National Insurance Contributions (NICs)? 

Foster carers may need to pay Class 2 or Class 4 National Insurance, but many are exempt due to low taxable profits. 

The rules: 

• If your taxable profit is under £6,725/year, you don’t pay Class 2 or Class 4 NICs. 

• If it’s over £6,725, Class 2 may apply. 

• Class 4 is only due if profit exceeds £12,570 (2025–26 figures). 

However, even if you don’t owe National Insurance, you might choose to pay Class 2 voluntarily to protect your state pension, maternity allowance and other state benefits. 

It’s worth speaking to a financial adviser or checking directly with HMRC to make the best choice for your situation. 

Claiming Expenses And Allowances 

Whether you use the simplified method or the profit method, understanding expenses is key, especially if you ever need to switch calculation methods or file detailed records. 

So, what exactly can you claim for? 

Allowable expenses for foster carers 

If you opt for the profit method, you can deduct reasonable, fostering-related expenses before calculating tax. These may include: 

• Food, clothing and toiletries for the child. 

• Travel costs (e.g. school runs, contact visits, therapy appointments). 

• Toys, games and entertainment. 

• Bedroom furnishings or equipment. 

• Training costs (if not reimbursed by your agency). 

• Mileage (usually at HMRC’s approved rate). 

Remember – anything reimbursed by your agency (like Mosaic Foster Care) cannot be claimed again as a deduction. 

Keeping records as a foster parent 

Regardless of your method, it’s sensible to keep: 

• Receipts for any child-related purchases. 

• A simple income log showing dates and amounts. 

• Notes on which child each expense relates to (if fostering multiple children). 

Keeping tidy records helps you if you’re ever asked to switch to the profit method, you face an audit or need to explain a specific expense and if you generally want to be confident you’re staying within HMRC rules. 

Pro tip: Even if your fostering income is exempt from tax, completing your Self-Assessment accurately helps protect your entitlements including state benefits and access to voluntary National Insurance credits. 

Common Questions: Foster Carer Tax FAQs 

Even with clear guidance, foster carer tax rules can result in some eyebrow-scratching moments. Let’s tackle a few of the questions we hear most often. 

1. Do I need to register as self-employed? 

Yes. Even if your fostering income is entirely covered by Qualifying Care Relief, you must register with HMRC as self-employed and complete a Self-Assessment tax return each year. 

2. Do I still need to file a tax return if I don’t pay tax? 

Yes. If you receive any fostering payments, HMRC requires you to file a return even if your income is fully exempt under the simplified scheme. 

3. Can I still claim Child Benefit or Universal Credit? 

Yes – usually. Fostering income does not count towards Child Benefit means-testing, and is generally ignored by Universal Credit. But always check your personal circumstances with a qualified adviser. 

4. Do I need to complete multiple tax forms? 

Not usually. Your Self Assessment tax return is the main form, and you’ll typically just add details of your fostering income under the self-employment section. If using the simplified method, HMRC will ask for your total income and whether your income is below the qualifying amount. 

5. Can I speak to someone about my specific tax situation? 

Yes. HMRC has lots of useful information and you can reach out directly to Fosterline on 0800 040 7675 for free advice or get in touch with the Fostering NetworkAlternatively, speak to Mosaic Foster Care – we’ll point you in the right direction for trusted financial guidance.
