I'm an attorney, and do some side work for my dad. He's also an attorney and is self-employed (LLC). He collects a fee for trusts, which I write. I do the work, he gives me half of the fee.. How do I file? I'm newly licensed, about a year. He charges $400 for a trust. I spend hours writing it, communicating with the customer, etc. I often meet with the customer, and provide notary services. The customer writes a check to my dad's firm. (LLC) My dad writes me a check for half, $200. I'm trying to figure out how to claim this income, and what deductions/expenses I can apply. This is really a service to help my dad grow his business, and I definitely do not make wages worthy of my services. Of course, all income will be filed, but how do I maximize the benefit?
