Tax codes can often seem confusing, especially when you're trying to understand how they affect your income and the amount of tax you pay. Whether you're employed, self-employed, or receiving a pension, your tax code plays a crucial role in determining how much money is deducted from your earnings. In this blog, we'll break down what tax codes are, explain how to read and understand your tax code, and clarify what it means for your finances. By the end of this post, you'll have a clear understanding of how tax codes work and what to do if you think yours might be incorrect.
What Are Tax Codes?
A tax code is a combination of letters and numbers assigned to you by HM Revenue and Customs (HMRC) that tells your employer or pension provider how much Income Tax to deduct from your pay or pension. Essentially, it helps ensure that you pay the correct amount of tax throughout the year based on your income and personal circumstances.
How Are Tax Codes Formed?
Numbers: The numbers in your tax code indicate the amount of income you can earn before you start paying tax. For example, if your tax code is 1257L, the number 1257 means you can earn £12,570 tax-free in a tax year (which is your Personal Allowance).
Letters: The letters in your tax code provide additional information about your situation and how your tax should be calculated. For instance, the letter "L" typically means that you are entitled to the standard tax-free Personal Allowance.
Common Tax Codes and What They Mean
1257L: The most common tax code for the 2023/24 tax year, indicating you receive the standard Personal Allowance.
BR: Means you're taxed at the basic rate on all of your income from this job or pension (usually used if you have a second job or pension).
D0: Means you're taxed at the higher rate on all of your income from this job or pension.
D1: Means you're taxed at the additional rate on all of your income from this job or pension.
K: This code is used when your income or benefits exceed your Personal Allowance, meaning you have tax to pay on income that isn't being taxed elsewhere.
Understanding these codes is crucial because they directly impact how much tax is deducted from your earnings.
What Your Tax Code Means
Your tax code isn't just a random collection of letters and numbers—it directly influences how much Income Tax you pay. Understanding your tax code can help you ensure that you're not overpaying or underpaying tax. Here’s how to decode your tax code and what it means for your finances:
Breaking Down Your Tax Code
The Numbers: Your Personal Allowance
The numbers in your tax code (e.g., 1257 in 1257L) represent the amount of income you can earn tax-free. To determine this, HMRC multiplies the numbers by 10. For example, 1257 means you can earn £12,570 before you start paying Income Tax. This amount is usually based on your Personal Allowance, which is set by the government each tax year.
The Letters: Special Conditions
The letter in your tax code provides additional information about your circumstances and how your tax should be calculated:
L: You’re entitled to the standard tax-free Personal Allowance.
M: You've received a Marriage Allowance from your spouse or civil partner.
N: You've transferred part of your Personal Allowance to your spouse or civil partner.
T: Your tax code includes other calculations to work out your Personal Allowance (e.g., due to high income).
BR: All your income from this source is taxed at the basic rate (usually used for second jobs).
K: You have income that isn’t being taxed, and it’s greater than your tax-free allowance, so extra tax needs to be collected.
What to Do If Your Tax Code Seems Wrong
Check Your Pay Stub: Your tax code is usually shown on your pay stub or pension statement. If you notice a change or if the code doesn’t seem to reflect your situation, it’s important to take action.
Contact HMRC: If you believe your tax code is incorrect, you can contact HMRC directly to clarify. Common reasons for incorrect tax codes include changes in employment, multiple jobs, receiving taxable benefits, or changes in marital status.
Correcting Your Tax Code: If HMRC adjusts your tax code, your employer or pension provider will automatically update it, and any necessary adjustments will be made to your future pay.
Understanding your tax code and ensuring it’s correct can save you from unexpected tax bills and ensure that you're not paying more tax than you should be.
Common Letters in Tax Codes and Their Meanings
L:
Meaning: This is the most common letter and indicates that you are entitled to the standard tax-free Personal Allowance. If you see "L" in your tax code, it means HMRC considers you eligible for the standard Personal Allowance, which is the amount you can earn before paying tax.
M:
Meaning: The "M" code is used if you’ve received a Marriage Allowance transfer from your spouse or civil partner. This means your partner has transferred 10% of their Personal Allowance to you, increasing your tax-free allowance.
N:
Meaning: "N" indicates that you’ve transferred 10% of your Personal Allowance to your spouse or civil partner under the Marriage Allowance scheme. Your tax-free allowance is slightly reduced as a result.
T:
Meaning: The "T" code is used when your tax situation is more complex and requires HMRC to make additional calculations, such as when your income is higher than the Personal Allowance threshold, or you have other tax adjustments.
BR:
Meaning: "BR" stands for "Basic Rate." This code means that all of your income from this job or pension is taxed at the basic rate (20%) without any tax-free allowance. It's often used if you have more than one job or pension.
D0:
Meaning: The "D0" code means that all your income from this job or pension is taxed at the higher rate (40%). This is also used when you have more than one source of income and have already used up your basic tax-free allowance.
D1:
Meaning: "D1" indicates that all of your income from this source is taxed at the additional rate (45%). This is typically used for very high earners with additional income sources.
K:
Meaning: The "K" code is used when your taxable benefits or income are more than your tax-free allowance. Instead of allowing a tax-free amount, the K code increases the taxable amount, meaning extra tax needs to be collected from your income.
Less Common Letters in Tax Codes and Their Meanings
0T: No Personal Allowance is applied to your income, possibly because your Personal Allowance has already been used up or HMRC is waiting for information about your tax situation.
NT: No tax is deducted from your income. This is rare and usually applies to people who are not resident in the UK for tax purposes.
S: Your income is taxed using Scottish income tax rates.
C: Your income is taxed using Welsh income tax rates.
Understanding these letters can help you ensure your tax code accurately reflects your personal situation, helping you avoid paying too much or too little tax.
When are tax codes issued?
Tax codes are typically issued by HM Revenue and Customs (HMRC) at various times throughout the year, depending on your circumstances. Here are the common scenarios when tax codes are issued:
1. At the Start of the Tax Year (April):
Annual Update: Each new tax year, which begins on April 6th, HMRC issues tax codes to reflect any changes in the Personal Allowance or tax rules. If there are no significant changes in your situation, you’ll receive a new tax code automatically, often reflecting the updated Personal Allowance for that year.
2. When You Start a New Job:
New Employment: If you start a new job, your employer will need your tax code to calculate your tax deductions. HMRC will issue a tax code based on the information provided by you or your previous employer (often via your P45 form). If your employer doesn’t have your P45, they might use an emergency tax code temporarily until HMRC provides the correct code.
3. If You Change Jobs or Have Multiple Jobs:
Multiple Sources of Income: If you start a second job or have multiple sources of income, HMRC may issue new or additional tax codes to ensure that your income is taxed correctly across all your jobs or pensions. They’ll allocate the Personal Allowance to one job and may issue a BR, D0, or D1 code for the other.
4. When You Receive State Pension or Other Benefits:
State Pension: If you start receiving a state pension or other taxable benefits, HMRC will issue a new tax code to account for this income. Since the state pension is taxable but paid without tax being deducted, HMRC adjusts your tax code on other income sources (like a job or private pension) to collect the right amount of tax.
5. If Your Circumstances Change:
Change in Circumstances: Changes such as getting married, starting or stopping work, moving to a different tax jurisdiction (e.g., Scotland or Wales), or changes in taxable benefits can prompt HMRC to issue a new tax code. You should inform HMRC of such changes to ensure your tax code is updated accordingly.
6. If There’s a Change in Tax Legislation:
Legislative Changes: Sometimes, tax legislation changes in a way that affects how your income is taxed, such as adjustments to tax bands or allowances. In such cases, HMRC may issue new tax codes mid-year to reflect these changes.
7. When You’ve Underpaid or Overpaid Tax:
Adjusting for Overpayments/Underpayments: If HMRC discovers that you’ve underpaid or overpaid tax in the previous year, they may adjust your tax code to collect or refund the amount owed over the course of the current tax year.
8. Emergency Tax Codes:
Temporary Codes: If HMRC doesn’t have sufficient information about your income, they might issue an emergency tax code temporarily. This often happens when starting a new job without a P45. Emergency tax codes may result in higher tax deductions until the correct tax code is issued.
It’s important to check any new tax code you receive to ensure it’s accurate and reflects your current circumstances. If you think your tax code is wrong, contact HMRC as soon as possible to have it corrected.
How many tax codes should I have?
The number of tax codes you should have depends on your employment and income situation. Here’s a breakdown:
1. Single Employment or Pension:
One Tax Code: If you have only one job or pension, you should have just one tax code. This code will be used by your employer or pension provider to calculate the correct amount of Income Tax to deduct from your earnings.
2. Multiple Jobs or Pensions:
Multiple Tax Codes: If you have more than one job or pension, you might have a different tax code for each income source. HMRC will usually allocate your Personal Allowance (the amount you can earn tax-free) to one of your jobs, typically your main job or largest source of income.
Common Scenario: Your main job might have the standard tax code (like 1257L), while your second job could have a code like BR (Basic Rate) or D0 (Higher Rate), meaning the entire income from that second job is taxed at the appropriate rate without any tax-free allowance.
3. State Pension and Employment/Pension:
Two Tax Codes: If you receive a state pension and have another source of income (like a job or private pension), you will likely have two tax codes. The state pension is usually not taxed directly but will reduce your tax-free Personal Allowance on your other income. Therefore, your other income source will have a tax code that reflects this adjustment.
4. Benefits or Additional Income:
Adjusted Tax Code: If you receive taxable benefits (like a company car) or have other sources of taxable income (like rental income), HMRC might issue a tax code that takes these into account. This could be one tax code that adjusts for all these factors, or you might have separate codes if the income comes from multiple sources.
5. Emergency Tax Codes:
Temporary Tax Codes: In some cases, you might be given an emergency tax code temporarily until HMRC determines the correct code. This is often the case when you start a new job without a P45 from your previous employer. Once HMRC has the necessary information, they will issue the correct tax code.
Summary:
One Tax Code: For single employment or pension.
Two or More Tax Codes: If you have multiple jobs, pensions, or income sources.
If you have multiple income sources, it’s crucial to ensure that your tax codes are correct to avoid underpayment or overpayment of taxes. If you're unsure about your tax codes or think there might be an error, it's a good idea to contact HMRC or consult with a tax professional.
Conclusion: Take Control of Your Tax Code
Understanding your tax code is an essential part of managing your finances. It determines how much tax is taken from your earnings and ensures that you pay the right amount to HMRC. By breaking down the numbers and letters in your tax code, you can see exactly how much of your income is tax-free and what tax rate applies to the rest.
If you ever notice a discrepancy in your tax code, or if your circumstances change, it's crucial to address it quickly. A wrong tax code can lead to overpaying or underpaying tax, which can cause financial stress down the line.
