I've heard a lot about the Holy Bread game. I haven't tried it yet, but I'm going to try it soon with your referral link.

Regarding the income tax, the way I handle that for my personal business is by putting 25% of all business revenue into an account and I leave it there until tax time. If I need to pay extra, I take it from that account. Whatever is left in that account after my taxes are done, I take out and start over for the next year.
