Hello, I am about to take on 2 part time jobs and freelancing work, and I'm wondering how this will work in terms of how my tax and NI contributions will be calculated. My total income over the 3 sources won't be over £40,000. How do I include this on the self-assessment form so HMRC know that I will also have paid tax on 2 other jobs? I'm worried about getting emergency taxed but also equally worried about not paying enough and ending up with a big bill! Any help and advice would be great. Thanks so much!
