USA Must primary tax payer know about dependent's EIN# and new business for taxes?

[New@Taxes]

Hi! My father is claiming me as a dependent for 2019. I started a LLC in 2019 that has its own EIN#. The LLC is an online retail dropshipping store, and neither it nor I made any income in 2019. I am also going to file for myself separately in order for the business to be put down on record as having filed taxes for its first year, however I haven't told my Dad about how I have a business EIN# and LLC, because I want to surprise him when I make money, and the anticipation of the surprise motivates me to work really hard. Does he need to know about the EIN# and LLC for his taxes, please?

Above will teach you what qualifies for dependent test.
There is no test concerning whether or not you own an LLC or have a business EIN.
So by itself the fact that you have that does not need to be disclosed to him as it s not one of the tests.

Thank you for the help! It sounds strange not telling him, right? It is one of those dreams one should probably abandon where one can only keep going because of the end goal. At least, I'll try and build the business up to a little something he could be proud of … .

I think just the fact that you had the initiative to do this will make him proud. Good Luck!
