Multiple jobs - any issues?

[SupDuck]

I work, employed, part time. I’m an ex professional who burned out and am now working an enjoyable, but lower paid, job.
I am now feeling better and would like to work full time hours. I have the option of a few hours self employed work and a few causal hours in another job. The 3 jobs would give me a decent, but not high, income and it would be my ideal scenario.
Do I need to have any concerns about any tax or other implications doing this? TIA

It’s absolutely fine! The tax return form is designed to deal with multiple jobs.
if total income exceeds £50k consider setting up a limited company.

I have multiple jobs and havent found any problems tax wise.

I have found that some employers offer better terms and conditions for employees over certain thresholds, whether is better sick pay, holiday or pension contributions so i miss out on those.

You might want to check the employment rules with your current employer. If I wanted to work another job (even working part-time) I would need my employer permission.

Thanks all that’s great to know I can go ahead with plans.
Luckily, my current job has no restrictions on other work.

@concernedrepurplehouse The self
employed work will only be a few hours a week and less than £400 / month. The main 2 wages are employed. Would I just do a tax return for that low amount as the employed jobs will be taxing me directly.

@SupDuck if you have more than one employment then you might need to split your tax code. It depends if you'll be using all of your personal tax allowance in one job. If you won't, you can split it with your second job. It does mean having a good idea what your regular earnings will be.

Ignore if you'll be earning more than the allowance in your main role.

I don’t know
