Tax on income

underling

Hi could someone please tell me how to work out how much tax I should be paying.
I currently receive-
rent from lodgers- £500 per month,
rent from another property which is supposed to be £350 per month, but usually is less as money gets take out for repairs(its rented through an agency).
I recently started a new job. I have no set hours (zero hour contract), I have worked one week so far and have earnt £149. (my job is weather dependent, so on a good week ill be working 6-7 hours a day 6 days a week) I get paid £6 per hour and was told by ,my boss that he pays any tax due. I get paid in cash and don’t get given a wage slip.
I am also about to start another part time job and will be earning another £240 per month.
I have never earnt enough to pay tax before, and would like to know how to work out what I should be paying.
Also is £6 per hour below min wage (im 23)? Is that allowed because the tax is not taken out of my wages?

Minimum wage is currently £6.19.

You should get a payslip. Being cash in hand doesn't help you.

Under the rent a room scheme https://www.gov.uk/rent-room-in-your-home/the-rent-a-room-scheme you can have £4250 tax free a year. With £500 a month lodger money, you are over this.

Having 2 jobs will complicate matters as you will either have 1 personal allowance tax code, or 2 full (which you would need to sort out, you should fill in a P46 before you join your new employer and say you have a job), or something different. You really need payslips to see your tax code though.
