If you run a business or side hustle, while also paying tax through PAYE (for example, because you’re employed or receiving a company pension), you may be able to pay your Self Assessment tax bill through your PAYE tax code. This isn’t for everyone, and there are specific requirements you’ll need to tick off first, so we’ll look at who qualifies, and how it works.
PAYE stands for Pay As You Earn, which is the system employers use to deduct tax and National Insurance from employees each time they pay them. The amount they need to deduct depends on how much the employee earns, any tax allowances they’re entitled to, and what tax code they’re on.
Understanding your tax code may be confusing at first, as it’s just a series of numbers and letters. The letters usually refer to any tax allowances you’re entitled to, or whether you’re paying emergency tax (which can happen if it’s unclear what tax code you should be on, so you get ‘emergency taxed’ instead – usually paying too much tax, so speak with HMRC to get this fixed!).
The most common letter is L, which means you qualify for the normal amount of tax-free personal allowance. The numbers indicate how much tax-free you’re entitled to for that tax year.
Your Self Assessment tax return form will (normally) automatically default to the option which allows HMRC to collect the tax you owe through your tax code, but you can opt out of this by unchecking the box.
If you opt in, your employer will be notified by HMRC that your tax code has changed, and this new tax code will tell them how much to deduct from your wages each time they pay you. The deductions which HMRC tell them to make will cover what you owe after submitting your Self Assessment tax return.
This change to your tax code might give your employer reason to suspect that you have another source of income – which is something to consider if you don’t want them know about a side-hustle!
The tax you owe for Self Assessment will be deducted from your salary or pension in equal installments, similar to income tax or National Insurance payments. It’s spread out over twelve months, so you don’t need to pay up all at once!
To pay your tax bill through your PAYE tax code, you’ll need to meet all three conditions set by HMRC:
There are some exceptions to paying your Self Assessment tax bill through your tax code:
This depends on your circumstances, but some people prefer to pay through their tax code, so they don’t have to worry about paying manually. The tax will simply be collected in equal installments across the tax year (which is also great for your cash flow).
It’s worth noting that paying your tax bill this way means your tax code will change and your employer will be notified, so they’ll know you’ve submitted a Self Assessment return.
If you’ve spoken to your employer about this, it’s nothing to worry about! But it’s worth thinking about if you don’t want your employer to know about your side hustle, or if there are rules in your contract to suggest you can’t work outside of your employment.
If you meet all the requirements and you’re happy to pay your taxes through your tax code, you must submit your online Self Assessment by the 30th of December. If you submit paper returns, the deadline for this is the 31st of October instead!
