Taxation of Profits from Loan Interest as an LLC

[Yael Fuerst]

Hi,

I have an LLC that I opened for my real estate properties and have an opportunity to loan $30,000 for 10% over 1 year.

My question is what would be my tax on the profit? From reading other posts do I understand correctly that it is 15%?

Are there any tax benefits in receiving the interest in monthly installments as opposed to the end of the year when loan is returned? 

Thanks!
