what is tax code 1257l?

What Is the 1257L Tax Code?

The 1257L tax code stands as the most common tax code issued in the UK by HM Revenue and Customs (HMRC) to salaried employees and pension providers. It is a critical component in determining an individual's tax obligations, specifically how much of their income is tax-free through personal allowances and how much must be paid to the government. The number "1257" represents a personal allowance of £12,570, which is the yearly income an individual can earn tax-free. The letter "L" indicates that the person is eligible for the standard personal allowance.

How Is 1257L Calculated?

This personal allowance is typically distributed in equal portions throughout the year, for example, equating to £242 per week or £1,048 per month if paid weekly or monthly, respectively, or £241 per week and £1,047 per month.

Who Receives the 1257L Tax Code?

The 1257L tax code typically applies to people with a single job and an income that doesn't reach higher tax brackets. It is also usually issued to those who are under the State Pension age, do not claim the Blind Person’s Allowance or Marriage Allowance, have a good track record of paying taxes, and have not recently changed jobs or moved into a higher income category. This code was introduced in April 2021, replacing the previous common code of 1250L, and has been confirmed to be frozen until at least April 2028.

While the 1257L code is accurate for the majority of employees with a single job and no additional benefits or allowances, your tax code is not static and can change from 1257L due to a variety of circumstances. HMRC usually updates your tax code as your circumstances change. Understanding these potential changes is crucial for ensuring you pay the correct amount of tax and avoid financial discrepancies.

When Might Your Tax Code Change from 1257L?

Changes to your tax code, including a deviation from 1257L, can arise from several primary categories of events:

1. Employment Shifts or Income Changes

A significant factor leading to a change in your tax code is alterations in your employment status or the number and type of your income sources.

• Starting a New Job: When you start a new job, your tax code can change, especially if your new employer does not have all the necessary information to correctly tax your pay. This can sometimes result in an emergency tax code being applied initially.
• Having Multiple Jobs or Income Streams: If you take on more than one job, or if you have multiple sources of income, such as a full-time job and a private pension, your tax code will likely change. For example, if you have multiple pension sources, HMRC might classify your taxes under codes like BR or D0. Your personal allowance, typically £12,570 with 1257L, may need to be split across these income sources, leading to different tax codes for each. If the allowance is split incorrectly across multiple jobs, it can lead to overpaying tax and potentially a rebate.
• Starting, Leaving, or Retiring During the Tax Year: Any changes in employment status mid-year, such as starting a job part-way through the tax year or retiring, can affect how your personal allowance is applied. The 1257L tax code is cumulative, so if you go back to work after a break or start mid-year, your tax-free personal allowance accumulates, which could result in paying less tax for a while.
• Transitioning to a Higher Income Category: The 1257L tax code primarily applies to individuals whose income does not fall into higher tax brackets. If your earnings increase significantly and you jump into a higher income category, your tax code might be adjusted to reflect this change, even if the personal allowance remains the same. For example, while the first £12,570 is tax-free, earnings between £12,571 and £50,270 are taxed at 20%, between £50,271 and £125,140 at 40%, and over £125,140 at 45%.
• Receiving Untaxed Income: If you begin to receive income that is not taxed at the source, this can necessitate a change in your tax code to ensure the correct amount of tax is collected.
• Becoming Self-Employed: It's important to note that self-employed individuals do not receive tax codes; instead, they report their annual income and calculate their taxes through the self-assessment system. If you transition from employment to self-employment, your tax code will effectively cease to apply in the same way.

2. Changes in Allowances or Benefits

Your tax code is a direct reflection of your personal allowance, which can be adjusted based on any allowances or benefits you receive. These adjustments can either increase or decrease your tax-free income, thus altering your tax code from 1257L.

• Taxable Company Benefits: If you receive taxable company benefits, such as a company car, private medical insurance, or a health club membership, your tax-free allowance will typically be reduced to account for the tax owed on these benefits.
• • For instance, if your employer provides you with a company car benefit valued at £5,000 annually and a health club membership worth £800 per year, your standard £12,570 allowance would be reduced. The calculation is £12,570 - £5,000 - £800 = £5,770, resulting in a new tax code of 577L.
  • Another example highlights a Chartered Accountant with a medical benefit of £380 and a car benefit of £6,000. Assuming an allowable expense of £500 (which would typically increase the allowance), the calculation is £12,570 (standard allowance) + £500 (allowance) – £380 (medical benefit) – £6,000 (car benefit) = £6,690, resulting in a tax code of 669L.
  • Similarly, if someone with a 1257L code starts receiving a taxable company car benefit worth £1,000 per year, their tax code would change to 1157L, reflecting a reduced tax-free allowance of £11,570 (£12,570 - £1,000). These reductions ensure you pay the correct amount of tax on your total income, including benefits.
• Tax-Deductible Allowances/Expenses: Conversely, if you have certain allowable expenses that can be claimed against your income, these can increase your tax-free allowance.
• • For example, if you pay an annual professional subscription fee (like to the Institute of Chartered Accountants or British Design Association) that is considered an allowable expense by HMRC, this amount is added to your personal allowance. If this subscription costs £500, your allowance would become £12,570 + £500 = £13,070, resulting in a tax code of 1307L.
  • If the professional subscription fee is £300, your tax-free allowance increases to £12,570 + £300 = £12,870, leading to a tax code of 1287L.
• Specific Allowances: Claiming certain specific allowances will also lead to a change from the 1257L tax code:
• • Blind Person’s Allowance: If you are eligible for the Blind Person's Allowance, your tax-free income will be significantly higher than the standard 1257L allowance. This could result in a 1544L code, indicating a total personal allowance of £15,440.
  • Marriage Allowance: This allowance lets a lower-earning partner transfer part of their unused personal allowance to their higher-earning spouse or civil partner. If one partner earns under £12,570 (and thus doesn't fully use their allowance) and the other earns above £12,570, the tax codes may change to 1370M (for the recipient of the allowance) or 1185N (for the one transferring it).

3. HMRC or Policy-Driven Changes

Beyond individual circumstances, broader administrative and governmental decisions can also impact your tax code.

• Annual Updates and Notifications: HMRC updates tax codes annually, typically sending out PAYE coding notices (P2 forms) between January and March each year. These notices reflect any adjustments to your personal allowance or other factors that influence your tax code. Even if your code is 1257L, you might receive a P2 form simply to confirm this for the new tax year.
• General Changes in Tax Rules: The government can implement changes to overall tax rules and personal allowances, which can lead to widespread adjustments in tax codes. For instance, the 1257L code was introduced in April 2021, replacing the 1250L code due to a change in tax regulations. While the £12,570 personal allowance is currently frozen until at least April 2028, historical changes have seen personal allowances (and thus tax codes) increase by small amounts each year.
• HMRC System Errors: Given the vast number of tax codes managed by HMRC, errors can occasionally occur in their system, leading to an incorrect code being assigned to an individual. Such errors can also arise from misinformation related to job changes, pension issues, or new income sources.
• Emergency Tax Codes: You might find your tax code changed to an emergency tax code such as 1257L W1, 1257L M1, or 1257L X. This often happens when HMRC does not have enough information about your income. Common scenarios for emergency tax codes include starting a new job, starting to receive a State Pension, or beginning work for an employer after a period of self-employment. Under an emergency tax code, your tax-free personal allowance is applied solely to each individual pay period, such as weekly or monthly, instead of being spread across the entire tax year.

4. Regional Variants of the 1257L Code

It is also important to remember that tax codes can differ slightly based on your location within the UK. While 1257L is the most common code in England and Northern Ireland, Scotland has introduced its own tax rates, which may differ slightly from the rest of the UK. For instance, in Scotland, the equivalent tax code is S1257L, and in Wales, it is C1270L.

What Happens If Your Tax Code Is Incorrect?

Having the wrong tax code can lead to serious financial consequences for a person. It can lead to either overpaying tax (meaning you receive less in your take-home pay than you should) or underpaying tax (which can result in fines from HMRC). If you have overpaid tax, you might be due a tax rebate. This often occurs if your tax code is wrong or if you had multiple jobs and your combined income was taxed too highly. HMRC would typically inform you of any overpayment via a P800 form, detailing how to claim your rebate.

How to Check and Correct Your Tax Code

Given the importance of your tax code, it is crucial to know where to find it and what to do if you suspect it is incorrect.

• Where to Find Your Tax Code: You can typically find your tax code on your payslip (often near your National Insurance number), on your P60 or P45 documents (which provide overviews of your annual earnings and withholdings), or on a Tax Code Notification (P2) issued by HMRC whenever there is a change to your code. Additionally, you can access your Personal Tax Account on the official HMRC website for complete information.
• What to Do if Your Tax Code is Incorrect: If you believe your tax code is wrong, it is paramount to contact HMRC immediately to minimise any tax errors. You can do this by:
• • Checking your current tax code on your payslip or HMRC account.
  • You can contact HMRC directly by calling 0300 200 3300 or 0300 200 3310.
  • Logging into your personal tax account on the HMRC website and using the online service to confirm or update your details.
  • When contacting HMRC, you should be prepared to provide accurate information such as your National Insurance number, details of any job changes, current employment proof, and salary slips. HMRC will then review your case and issue a new code if necessary.

Regularly checking your payslips and staying informed about tax rules are vital steps to avoid tax payment errors. Even though the 1257L tax code is the most common in the UK, mistakes can happen due to various factors, making proactive monitoring essential for ensuring your tax affairs are in order.
