No tax deducted from wages

rr88

Until a few weeks ago, I was working a full-time job. 
A few months before I left, I took on a part-time job at the weekends.
For my part-time job, I dont appear to have had any tax deducted from my wages. I checked my HMRC account online as it emailed me about something along the lines of a change in tax code (around the same time as my first lot of wages from my part-time job).
So I've logged in and can see each of my wages on there, but with no tax deductions.
I didn't realise any of this until now because we don't get payslips at our job.
I am also self-employed, so will I just pay the tax for this when I come to do my tax return?
This is quite annoying as, if I hadn't have been registered as a sole-trader, then I wouldn't have got an email and probably been totally unaware that I was accruing a massive tax bill

Several alarm bells ringing here.

Employers must provide pay slips. Start there and ask for them.

You also need to get your tax code changed so tax is deducted, especially now this is your main job.

It will all come out on the wash through your Self Assessment return but it sounds like you would be better off with a BR (or SBR) tax code from now on.
