We are using the standard tax rate recommended by the Swedish tax agency for "egenantällningsföretag", which is set at 30%. For future payouts we can set a lower or higher rate for you, however to get a lower rate you have to apply for "jämkning" (application for reduced tax) from the Swedish tax agency. Please note that this can only be applied for your primary employer, if you receive salaries from several employers at once you should only ask your primary employer for a reduced tax rate.
You can find further information about this on the tax authority website:
