What is Tax Code 500T?

Updated: May 22

Decoding Tax Code 500T: An Introduction

The 500T tax code in the UK is a temporary, non-cumulative tax code used by HM Revenue and Customs (HMRC) in situations where they lack sufficient information to assign a standard tax code. It often appears when starting a new job without a P45, in complex tax situations, or as an emergency tax code. The 'T' signifies items in your tax affairs needing regular review. This code means each pay period's tax is calculated separately, without considering the year's previous earnings or tax paid, potentially leading to over or underpayment of tax, requiring later adjustments.

The UK tax system uses tax codes to determine how much income tax an individual should pay. Each tax code is unique and reflects the taxpayer's circumstances, including allowances, deductions, and any additional incomes. Understanding your tax code is crucial for ensuring you're not overpaying or underpaying taxes.

Deciphering the 500T Tax Code

The 500T tax code is one that often confuses taxpayers. At its core, this code is used by HM Revenue and Customs (HMRC) in specific situations. It differs from standard tax codes due to its temporary nature and the manner in which it is applied to your income.

What is Tax Code 500T

When is the 500T Code Used?

  1. New Employment: If you start a new job and your employer doesn't have all the necessary details to determine your correct tax code.

  2. Complex Tax Situations: For individuals with multiple income sources or complicated tax affairs, the 500T code may be used temporarily.

  3. Emergency Tax Code: At times, it functions as an emergency tax code, particularly when HMRC needs more information to calculate the correct code.

Understanding the 'T' in 500T

The 'T' in the tax code is significant. It indicates that there are items in your tax calculation that need reviewing annually. These items could include taxable company benefits, State benefits, or adjustments for underpaid tax from previous years.

How the 500T Tax Code Affects You

  1. Income Tax Calculation: Under the 500T code, your income tax is calculated on a non-cumulative basis. This means each pay period is treated as separate, without considering previous earnings or tax paid in the tax year.

  2. Potential for Over or Underpayment: Due to its temporary and non-cumulative nature, there's a risk of overpaying or underpaying tax. It's essential to rectify the situation quickly to avoid financial surprises.

Navigating the Implications of the 500T Tax Code

Immediate Steps to Take

  1. Verify Personal Details: Ensure your employer has accurate and updated personal details, including your National Insurance number.

  2. Contact HMRC: Reach out to HMRC to provide any missing information or to understand why you've been assigned this code.

Understanding Pay Slips

Your pay slip under a 500T code will show your income and the tax deducted for that specific period only. Keep a close eye on these figures, as they can fluctuate based on your earnings and the temporary nature of the code.

A Real-Life Case Study of Someone Using the 500T Tax Code

Case Study: Sarah Thompson


Sarah Thompson, a 35-year-old marketing consultant from Birmingham, recently switched jobs and encountered the 500T tax code. Sarah's previous employer did not provide her with a P45 upon leaving, which led to her new employer assigning her a temporary tax code. This case study explores Sarah's journey to understand and rectify her tax code, ensuring compliance with HMRC regulations while managing her finances effectively.

Initial Encounter with the 500T Tax Code

Upon starting her new job in January 2024, Sarah received her first payslip and noticed a significantly higher tax deduction than expected. Her payslip showed a 500T tax code. Concerned about the high tax deduction, Sarah decided to investigate further.

Understanding the 500T Tax Code

Sarah learned that the 500T tax code is a temporary, non-cumulative code used by HMRC when they lack sufficient information to assign a standard tax code. The '500' denotes her tax-free personal allowance of £5,000 for the year, while the 'T' indicates that her tax affairs need regular review due to incomplete information.

Seeking Professional Help

Realizing the complexity of the situation, Sarah sought assistance from a tax advisor, Michael Green, at My Tax Accountant. Michael explained the implications of the 500T tax code and outlined the steps Sarah needed to take to resolve the issue.

Initial Consultation and Information Gathering

During the initial consultation, Michael asked Sarah for the following documents:

  • Her most recent payslips from both her current and previous employers.

  • Any P60s or P45s from the previous tax year.

  • Details of any other income sources, such as rental income or investments.

Calculating the Impact of the 500T Tax Code

Michael helped Sarah understand the immediate financial impact of the 500T tax code. Using her January payslip, they calculated her tax liability:

  • Monthly Salary: £4,000

  • Personal Allowance (under 500T): £5,000 annually (£416.67 monthly)

  • Taxable Income: £4,000 - £416.67 = £3,583.33

Assuming Sarah is a higher-rate taxpayer:

  • Basic Rate (20%) on £3,583.33: £716.67

  • Total Tax Deducted: £716.67

Sarah noticed she was overpaying tax compared to her previous job due to the lower personal allowance under the 500T tax code.

Contacting HMRC

Michael advised Sarah to contact HMRC to provide the necessary information for a correct tax code. Sarah called HMRC and provided the following details:

  • Her National Insurance number.

  • Details of her previous employment and income.

  • Confirmation that her new employer had not received a P45.

HMRC requested that Sarah send in her last payslip from her previous job and a letter explaining the situation.

Submitting Documents to HMRC

Sarah sent the required documents to HMRC via registered post, ensuring they were received promptly. Michael recommended keeping copies of all documents and obtaining proof of postage for record-keeping purposes.

HMRC's Response

Within three weeks, Sarah received a letter from HMRC confirming that her tax code had been updated to 1257L, which is the standard code for most taxpayers for the 2024/25 tax year. The '1257L' code reflected her full personal allowance of £12,570.

Rectifying Overpaid Tax

With the correct tax code now in place, Sarah's subsequent payslips showed reduced tax deductions. However, she had overpaid tax in January due to the 500T code. Michael guided her on how to claim a refund for the overpaid tax.

Claiming a Tax Refund

Sarah completed a form P50, "Claiming Tax Back When You Have Stopped Working," and submitted it to HMRC along with her January payslip showing the overpayment. She opted for the refund to be paid directly into her bank account.

Monitoring and Adjusting Tax Codes

Michael advised Sarah to regularly check her HMRC online account and payslips to ensure her tax code remained correct. He also recommended updating her tax code if her circumstances changed, such as starting a new job or having additional income sources.

Calculations and Figures

Example Calculations:

  • Salary: £4,000 per month

  • Correct Personal Allowance (1257L): £1,047.50 per month

January Payslip under 500T:

  • Taxable Income: £4,000 - £416.67 = £3,583.33

  • Tax Deducted: £716.67

February Payslip under 1257L:

  • Taxable Income: £4,000 - £1,047.50 = £2,952.50

  • Tax Deducted (20%): £590.50

Overpayment in January: £716.67 - £590.50 = £126.17

Long-Term Implications and Best Practices

Michael provided Sarah with long-term tax planning advice, emphasizing the importance of:

  • Keeping personal and employment details up-to-date with HMRC.

  • Regularly reviewing pay slips and tax codes for accuracy.

  • Utilizing HMRC's online services to track tax status and make necessary adjustments promptly.

Sarah's experience with the 500T tax code highlights the importance of understanding tax codes and taking proactive steps to resolve any discrepancies. By seeking professional help and promptly addressing the issue with HMRC, Sarah ensured her tax affairs were in order, avoiding potential financial surprises.
