Thankyou for your reply, however based on my previous thread ...

I'm not yet sure if I'll declare the income from the app as 'self-employment income' or 'hobby income'. But regardless of that, would what you're saying also apply if I were to file this income as 'hobby income' ?
Also, in what condition would a non-resident of a state need to file a non-resident state tax return for that state ? Isn't an app sold considered a source of income from that state ?
