(edit title) Starting a first job in Sweden Needs to inform who? Options

[Somebody]

When a person starts first job in Sweden and so far has been only
SFI student not registered as unemployed person and living with working sambo
who should be informed about it?

- Migrationsverket?
- Skatteverket?
- Forsakringskassan?

or maybe the employer deals with that?

this will be casual job only, called when needed and paid per hour

TIA

Maybe I did this wrong, but no one?

If you have your personal number, you need to give that to your employer and you should be good to go. At least that's how I've always done it.

Never registered as unemployed though.

If you start working and want the possibility of getting unemployment insurance, then you need to join A-kassan.

However, I noted that you said that you were part time etc. If it is a bemanningsföretag then it could be of no use, since there are exceptions to people employed in such circumstances.

Other than that, it may be an idea to notify Fk of your new income. But again, if you are temporarily employed it might not lead to anything.
