THE 50-30-20 BUDGETING RULE

WHAT IS A TAX CODE?

The 50-30-20 rule serves as a beneficial tool for budgeting, aiding in the effective management of spending. According to this guideline, you divide your monthly income into three categories: needs, wants, and savings. Establishing clear allocations for each category facilitates adherence to your budget and ensures better control over your expenditures.

Your tax code, comprised of both numbers and letters, plays a crucial role in determining the amount of income tax and national insurance you owe. If your tax code is inaccurate, you might end up paying more tax than necessary. You can locate your tax code on your payslip or P45, typically situated near your national insurance number.

Our comprehensive guide covers everything you need to understand about how tax codes function, the significance of the letters in your tax code, and steps to take if you suspect your tax code is incorrect.

HOW IS MY TAX CODE CALCULATED?

Initially, your tax allowances are computed, typically including your personal allowance (which is £12,570 for the tax year 2022/23), along with any additional allowances and job-related expenses, if applicable.

Next, your deductions are calculated, encompassing any income that you haven’t yet paid tax on, such as earnings from part-time work or state benefits.

Subsequently, your deductions are subtracted from your total tax allowances. This resulting figure represents the total income you’re permitted to earn before you become liable to pay tax.

Example: 1200L tax code would mean your personal allowance is 12,000

TAX CODE LETTERS AND WHAT THEY MEAN

Your tax code may not always include the common ‘L’ depending on your specific tax circumstances. Here’s a breakdown of the various letters used by HMRC in tax codes, along with their meanings:

– L: You are entitled to the standard tax-free allowance.
– M: Marriage allowance – You have received 10% of your partner’s allowance.
– N: Marriage allowance – You have transferred 10% of your allowance to your partner.
– S: Your income or pension is taxed using Scotland’s rates.
– T: Your allowance is reduced because your income exceeds £100,000.
– 0T: Your allowance is fully utilized, or you’ve begun a new job and your employer lacks the necessary details for a tax code.
– BR: You are taxed at the basic rate.
– D0: Your income or pension is taxed at a higher rate, typically applicable if you have more than one job.
– D1: Your income or pension is taxed at an additional rate, usually if you have more than one job.
– NT: You do not pay tax on your income.
– S0T: Your new employer does not possess the details required to assign you a tax code.
– SBR: Your income or pension is taxed using Scotland’s rates.
– SD0: Your income or pension is taxed using Scotland’s intermediate rate.
– SD1: Your income or pension is taxed using Scotland’s higher rate.
– SD2: Your income or pension is taxed using Scotland’s top rate.
– CBR: Your income or pension is taxed using Wales’s rates.
– CD0: Your income or pension is taxed using Wales’s higher rate.
– CD1: Your income or pension is taxed using Wales’s additional rate if you have more than one job.
– C0T: Your allowance has been utilized, or you’ve commenced a new job, but your new employer lacks the necessary details for a tax code.

EMERGENCY TAX CODE

If your tax code has ‘W1’ or ‘M1’ or ‘X’ at the end, then you are paying emergency tax, these will show on your pay slip as:

– 1250 W1

– 1250 M1

– 1250 X

You may be put on to an emergency tax code if you:

– Have started a new job

– Are working for an employer after being self-employed

– Are receiving company benefits or state pension

K TAX CODE

If your tax code begins with a ‘K’, it indicates that you’re not currently being taxed on that income because the tax deductions owed from previous years exceed your personal allowance. This typically occurs in the following situations:

– You are settling the previous year’s tax owed through your wages or pension.
– You are receiving taxable benefits, such as state benefits or company benefits.

WHAT IF MY TAX CODE IS WRONG?

It’s crucial to ensure you’re on the correct tax code because incorrect tax deductions can impact your state pension in retirement. If you’ve overpaid tax, you can claim a refund, but if you’ve underpaid, you’ll need to settle the shortfall with HMRC.

If you suspect you’re on the wrong tax code, it’s essential to contact HM Revenue & Customs promptly. Being on an incorrect code may result in either overpaying or underpaying tax on your salary. If you’re paying too much, you can claim a tax rebate.

AFTER YOUR TAX CODE CHANGES

If your tax code has been changed HMRC will write to you or email, they will also tell your employer or pension provider that your tax code has changed. Your next payslip will then show your new tax code and any adjustments to your pay if you were paying the wrong amount of tax.
