the percentage that you pay to a gym can be considered equipment rental.
It is rather strange that your clients have to pay the gym which in turn pays you. That is not consistent with the status of an independent contractor.
This is similar to the way the Government utilizes contractors. You may want to read the following article to ensure you are documenting everything appropriately in case you get audited.
Natalie, Josh, Karin, Michael,
Thanks for your input I appreciate it very much. I know this situation is a bit odd.
A few details, I have brought all of my clients to this gym, none were given to me.
I have no benefits.
I do not have to follow any guidelines about how to train.
I am not reimbursed for anything.
After reading a bit about independent contractors I think I will either be able to claim this as a write off, OR I am being misclassified by my employer and am actually an employee. I will take the advice given by you guys and seek out a tax professional.
