What is an Income Tax Code?
An income tax code is a unique identifier issued by HM Revenue and Customs (HMRC) in the UK. This code takes into account the personal allowance available to the taxpayer, additional entitlements, and any adjustments due to benefits in kind. Employers use this code through the PAYE (Pay As You Earn) scheme to calculate and deduct the right amount of tax from an employee’s wages or salary.
Key Features of Income Tax Code
- Issued by HMRC: The code is determined by HMRC based on various individual taxpayer-specific factors.
- Personal Allowance: Incorporates the personal tax-free allowance and any additional allowances.
- PAYE Scheme: Used by employers under the PAYE scheme to calculate and withhold the correct amount of tax.
- Benefits in Kind: Can be adjusted to include tax on non-cash benefits like company cars.
- Equal Deductions: Ensures that tax is deducted in equal amounts throughout the fiscal year.
Examples
- Default Code: If the standard personal allowance is £12,570, an income tax code for an employee might be 1257L, indicating no non-standard adjustments.
- Adjusted Code for Benefits in Kind: If an employee has a company car, their code might be reduced to, for instance, 1157L, to account for the taxable value of the car.
- Zero Tax Code: If an employee’s earnings are below the personal allowance right from the start, their tax code could be 0T, indicating no tax is to be deducted.
Frequently Asked Questions
How is the income tax code calculated?
The income tax code is calculated by HMRC considering the personal allowance, additional allowances, deductions for benefits in kind, and any adjustments from last year’s overpayment or underpayment.
Can the tax code change during the year?
Yes, HMRC can update your tax code at any time during the fiscal year if your circumstances change, such as receiving a new benefit in kind or if they’ve reassessed your previous year’s tax return.
What does the “L” at the end of the code signify?
The “L” signifies that the taxpayer is entitled to the basic personal allowance. Different letters at the end of the tax codes can indicate other allowances or specific circumstances.
What should I do if my tax code is incorrect?
If you believe your tax code is incorrect, you should contact HMRC to clarify and correct it. An incorrect tax code can result in paying too much or too little tax.
