2 part time jobs

[Bellamerlin02]

I have started as employed part time, earning less than 12000 gbp but also continue to work self employed part time also earning less than 12000 gbp which I have declared to hmrc for past 2 years.
How do I pay tax/declare for the 2 jobs?

Your employer will deduct tax for the employment and you will continue to do self assessment.

I earn ca 12000, so under the threshold so my employer didn't deduct tax (only been there for a month). I earn around 8-10000 self employed so also haven't been deducted tax for the last 2 years as was my only income until now. Do I tell my new employer they need to deduct it?

Ah ok, sorry I didn’t register the under £12k. The employer will deduct tax in line with the tax code that HMRC has issued. I assume you must have ticked statement A that this is your first employment in the tax year, which is accurate as your self employment is not employment. So they have presumably been issued a tax code that utilises the full personal allowance.

As such, you need to start to put aside money from your self employment for a later tax bill. When you come to complete self assessment you will fill in both the employment and self employment earnings and it will calculate what you owe.

On your self assessment tax return, you tell them you had £12k employment income no tax and £10k trade income. Then it calculates your tax and you pay it directly to HMRC.

Unless you mean that your "self-employed" income is also employment but one where your employer pretends not to be your employer to evade tax. In which case you have a problem.

If as you're registered as self employed with HMRC then you pay the tax & NI on your self employed income by the deadline for the relevant tax year, but it will be based on your total income/profits so I would set aside a portion of your self employed income for your SA bill.
