It’s late in the afternoon, I go downstairs to check the mail and low and behold, I’ve been paid—HOORAY. A check is there, written out to my business and I’m ready to mobile deposit it into my account. No matter how big or small the check is, this is an exciting day—someone is paying me for my services and that alone is pretty cool.   This is where things start to take a turn. You know you can’t take home every penny that you earn—there are taxes, business expenses .
