Common Mistakes When Claiming Tax Credits
Claiming tax credits can be a lifeline for many families and individuals. However, the process can be complex, and even small mistakes could lead to delays, incorrect payments, or penalties. To help you avoid these pitfalls, we’ve outlined the most common errors people make when claiming tax credits and how to prevent them.
1. Providing Incorrect Personal Details
One of the most frequent mistakes is submitting incorrect or incomplete personal details. Mistakes in names, addresses, or National Insurance numbers can cause delays in processing your claim.
How to Avoid:
- Double-check your personal information before submitting your application.
- Ensure all details match official documents like your passport or driver’s license.
2. Misreporting Your Income
Underestimating or failing to accurately report your income can lead to overpayments, which HMRC will ask you to repay. On the other hand, overestimating your income may result in receiving less support than you’re entitled to.
How to Avoid:
- Use your latest P60 or payslips to report your earnings.
- Include all taxable income, such as bonuses, dividends, and rental income.
3. Failing to Update HMRC About Changes
Life changes such as moving house, changing jobs, or having a child can affect your tax credit entitlement. Not informing HMRC about these changes can result in underpayments or overpayments.
How to Avoid:
- Notify HMRC immediately of any significant changes, such as:
- Changes in employment status.
- A new child or change in childcare costs.
- Moving in with a partner or separating.
4. Claiming Tax Credits You’re Not Eligible For
Some claimants apply for tax credits without fully understanding the eligibility criteria, leading to rejected claims or penalties.
How to Avoid:
- Check your eligibility before applying. You may qualify for working tax credits if:
- You work at least 16 hours per week (depending on your circumstances).
- Your income is below the threshold.
- Use a Working Tax Credit Calculator to verify your eligibility.
5. Missing the Annual Renewal Deadline
Tax credits must be renewed annually. Missing the renewal deadline can result in your payments stopping or being overpaid.
How to Avoid:
- Mark the renewal deadline in your calendar.
- Complete the renewal online, via the HMRC app, or by phone.
6. Not Keeping Records
Failing to keep financial records can lead to errors when completing your application or during a compliance check.
How to Avoid:
- Retain all relevant documents, including:
- Payslips.
- P60s and P45s.
- Childcare receipts.
- Keep records for at least one year after the tax year ends.
7. Misunderstanding Joint Claims
If you live with a partner, you are required to make a joint claim. Applying as a single individual when you’re part of a couple can lead to penalties and repayment demands.
How to Avoid:
- Review HMRC’s definition of a “couple” for tax credit purposes.
- Submit a joint application if you live with a partner, even if they have no income.
8. Ignoring Overpayment Notices
Overpayment notices from HMRC are not uncommon. Ignoring these notices can lead to further financial penalties and legal action.
How to Avoid:
- Contact HMRC as soon as you receive an overpayment notice.
- Set up a repayment plan if necessary.
9. Overlooking Childcare Costs
Failing to report eligible childcare costs can result in lower payments than you’re entitled to. Conversely, overreporting costs may lead to overpayments.
How to Avoid:
- Provide accurate figures for childcare expenses.
- Update HMRC if your childcare costs change during the year.
10. Not Using Available Tools
Many people make mistakes because they do not use the resources available to them, such as calculators or guidance tools.
How to Avoid:
- Use a Working Tax Credit Calculator to estimate your entitlement.
- Read official HMRC guidance or seek advice from a professional.
