I think the challenge with going freelancer will be with the things that are required of you as a corporate entity. Such as, reading up on legislation, accounting rules, dialog with tax office etc.
What is the salary tax breaking point for 2020?
When do you need to have declared and paid VAT during 2020 if you are one a 3 month schedule?
These are basic knowledge questions for a freelancer with a Swedish Aktiebolag, easily googleable in Swedish but challenging if you don't know it.
