overpayment Archives

If you’ve recently lost your job and are wondering how tax refunds on redundancy payments work and are considering claiming back tax you may have overpaid, you’ve come to the right place. Being made redundant is a challenging time, both emotionally and financially. Amongst the many adjustments, understanding your tax position might feel like an unwelcome extra burden. However, here at Taxfile, we know that many individuals who experience redundancy are actually due a tax refund or tax rebate. So, we’re here to cut through the jargon and help you get back what you’re owed.

Why You Might Be Due a Tax Refund After Redundancy

The PAYE Puzzle

The UK’s Pay As You Earn (PAYE) system is designed for a consistent annual salary. When your employment ends part-way through a tax year (which runs from 6th April to 5th April), your employer has likely been deducting tax based on the assumption you’d earn that full year’s salary. This often leads to an overpayment and a potential tax rebate after redundancy.

Here’s why this “PAYE puzzle” often results in an overpayment:

Annual Tax Calculation: The Unfinished Year — Your Income Tax liability is calculated for the entire tax year. If your income stops or significantly reduces due to redundancy, your actual annual earnings will be lower than anticipated. This means you’ve paid too much tax upfront on income you ultimately didn’t earn for the full year.
Emergency Tax Codes: A Common Culprit — Sometimes, a final payment or even the redundancy payment itself can be processed with an emergency tax code (like 0T M1). These codes deduct tax at a higher, non-cumulative rate, often leading to a larger tax deduction than necessary. It’s a “better safe than sorry” approach by HMRC that often means you’re overpaying.
Income Below Personal Allowance: The Tax-Free Threshold — For the 2024/2025 tax year, most people have a Personal Allowance of £12,570 – this is the amount you can earn tax-free. If your total income for the year, including any taxable redundancy elements, falls below this threshold, you’ll have paid tax unnecessarily on earnings that should have been exempt.

Understanding Tax on Redundancy Payments

Unpacking Your Package

This is often the most confusing part, and it’s where many people miss out. Not all money you receive when leaving a job is treated the same way for tax. Knowing the difference is key to calculating your potential refund.

The £30,000 Tax-Free Golden Rule — The first £30,000 of your genuine redundancy payment (compensation for loss of employment) is completely tax-free. This is a significant benefit designed to help individuals during this transition.
What’s Taxable Above £30,000? Any portion of your redundancy payment that exceeds £30,000 is subject to Income Tax at your marginal rate. Crucially, this excess is not subject to National Insurance Contributions (NICs), which is an important distinction from regular earnings.
Other Payments That Are ALWAYS Taxable (Beware the “Hidden Taxables”) — Be aware that some payments in your redundancy package are always taxable as normal earnings, regardless of the £30,000 threshold. These include:
- Payment in Lieu of Notice (PILON) — Whether it’s contractual or non-contractual, money paid instead of working your notice period is subject to Income Tax and National Insurance.
- Accrued Holiday Pay — Payments for any untaken annual leave.
- Outstanding Wages, Bonuses, or Commission — Any pay for work you’ve already done or earned.
- Restrictive Covenants — Payments for agreeing not to work for a competitor, for example.

Taxfile Insight: It’s vital not to simply assume your employer has calculated everything correctly. Over or underpayments can occur, and it’s ultimately your responsibility to ensure you’re paying (and reclaiming) the right amount of tax. We’ve seen many cases where a simple check of the redundancy payslip reveals significant overpayments.

How to Claim Your Tax Refund

Your Options (And How Taxfile Can Help)

The method for claiming back tax after redundancy largely depends on your individual circumstances. Here are the common routes:

The All-Important P45 — Your employer must provide you with a P45 when you leave. This crucial document summarises your pay and tax deductions for the current tax year. Keep all parts safe – you’ll need Parts 2 and 3 for most claims!
If You Remain Unemployed (for 4+ weeks) and Don’t Claim Taxable Benefits:
- You can often get an in-year refund by completing a Form P50 (“Claiming tax back when you’ve stopped working”). You’ll send this to HMRC along with Parts 2 and 3 of your P45.
- Alternatively, you can claim your refund online via your HMRC Personal Tax Account – this is often the quickest and most straightforward route if you’re comfortable with online services.
If You Start a New Job Quickly (within 4 weeks):
- Hand Parts 2 and 3 of your P45 to your new employer. They should then adjust your tax code, and any overpaid tax should be refunded through your new salary via PAYE. It may take a couple of pay cycles to see the adjustment.
If You Claim Taxable Benefits:
- If you’re claiming benefits like Jobseeker’s Allowance or Carer’s Allowance (which are taxable), the Benefit Office will typically manage your tax refund as your benefits affect your overall tax position. You’ll need to send them Parts 2 and 3 of your P45. (Note: Universal Credit is generally not taxable, so you might still claim directly from HMRC if that’s your only benefit.)
HMRC P800 Tax Calculation (The Automatic Review):
- After the end of the tax year (which is 5th April, so typically summer 2025 for the current tax year), HMRC reviews PAYE records. If they identify an overpayment, they’ll send you a P800 tax calculation, explaining how to claim your tax refund. Important: Since May 2024, HMRC often requires you to actively claim your P800 refund online, rather than sending it automatically. Don’t miss this!
Self Assessment Tax Return (For Complex Cases):
- If your tax affairs are more complex (e.g., you’re self-employed, have significant other income, or need to declare certain payments that fall outside standard PAYE), you might be required or choose to file a Self Assessment tax return. Any overpaid tax would then be reclaimed through this comprehensive process.

Important Deadlines: Don’t Delay! You can generally claim a tax refund for up to four tax years after the end of the tax year in which you overpaid. For example, for the tax year ending 5th April 2021, the deadline to claim would have been 5th April 2025. Don’t leave money on the table!

Beyond the Refund: What Else Should You Consider After Redundancy?

While getting your tax refund is important, redundancy can open up other financial considerations:

Pension Contributions — If you received a significant redundancy payment, consider whether a portion could be paid into your pension. This can offer significant tax relief and boost your retirement savings.
New Employment & Tax Codes — Ensure your new employer uses the correct tax code from your P45. If you don’t have one, they might put you on an emergency code initially, which could again lead to overpayments.
Becoming Self-Employed? Redundancy often sparks a move into self-employment. If this is your plan, you’ll need to register with HMRC as a sole trader and understand your new tax obligations (e.g., Self Assessment, Class 2 & 4 NICs). Taxfile specialises in supporting self-employed individuals!
Income Protection/Benefits — Review any income protection insurance you have, or explore eligibility for state benefits to bridge the gap.
Financial Planning — This is an opportune moment to review your overall financial health, budget, and future goals.

Have you ever felt that you’ve paid more in taxes than necessary? Whether due to calculation errors, changes in personal circumstances, or evolving tax laws, overpayments can happen to anyone. The good news is that there’s a way to reclaim those excess funds through the process of overpayment relief claims. In this comprehensive guide, we’ll walk you through the ins and outs of reclaiming your hard-earned money.

What is Overpayment Relief?

Overpayment relief allows you to recover money you’ve mistakenly paid to HMRC within four years after the end of the tax year in which the overpayment occurred. It’s a financial safety net that allows you to correct discrepancies and regain control of your finances. Understanding the concept is the first step toward putting your overpaid taxes back where they belong – in your pocket.

Types of Overpayment

The overpayment must be for income tax, capital gains tax (CGT), Class 4 National Insurance contributions (NICs), or corporation tax. It applies to both overpayments and excessive assessments.

Eligibility Criteria

You must have a valid reason for believing you overpaid tax. This could be an error in your tax return, incorrect coding by HMRC, or changes in your circumstances affecting your tax liability. You cannot claim overpayment relief simply by correcting your tax return after the deadline.

Claiming Overpayment Relief

You need to submit a formal claim to HMRC in the correct format, explicitly stating that it’s for “overpayment relief.”

The claim should clearly identify the tax year, the amount you believe you overpaid, and the reason for the overpayment. Include any supporting evidence, like documents confirming income, deductions, or expenses. Your claim must be submitted within specific time frames — generally, four years from the end of the tax year for which you’re claiming. Special rules apply for late claims.

Claim Format

Your claim must be made in writing, stating the tax year, the amount overpaid, the reason for your claim, and whether you’ve previously appealed. You cannot claim through your tax return.

For more information please refer to the HMRC website or get in touch with Taxfile.
