Is it correct that ‘in secondary occupation’ appears in my cost category when I enter purchase invoices from before the start of my sole proprietorship?

Were you also an entrepreneur in your secondary occupation at that time?

You can adjust this in your social security contributions, if I am not mistaken.

Can you provide some more information about this? If I adjust my status quarterly in the social security contributions tab, Dextra generates new calculations for social security contributions that I still have to pay. (Which is incorrect, of course.)

Would you be able to answer here? I am quite concerned!
