Can employer find out about my side business
I have a full time job that I like and I'm planning to keep. I do however need some extra income to be able to apply for mortgage. I have an opportunity to work on the weekends, but I need to register a small business in order to be able to receive the compensation.
I've gone through the contract I have with my full time employer and it states that I agree to devote all my time during working hours to them and that I will not take other employment without their approval.
I know them enough that if I ask for their approval, they will say no, so I won't bother even trying.
What are the ways my employer can figure out that I have a second job assuming that:
I will register my business as a "Sole proprietorship".
I will of course do my best as before during working hours at my primary job, so I will not under-perform.
I will not post anything online about my second job.
I will have to file taxes for both income sources.
