I'm considering making a loan to my sister-in-law to buy a car. Her current ride has 200k miles and has some reliability issues. Her job is a 30 minute commute through a rural mountainous area, so she is looking at buying a modest used car for 10-12k. Her credit is poor (500's) because of problems in the past where she missed payments. She was quoted a 12% interest rate.
My plan is to offer her a loan for 100% of the car value at 6% interest. She plans to sell her hooptie for around $1000 and use this to repay principle, as soon as practical. This is a win-win as far as I'm concerned - I accept the risk of the loan, I've had discussions with her about repayment, and I'm in a position to help her out without providing a handout.
My question is, if I provide this loan from business revenues, how does this affect our tax at the end of the year? I have a single-member LLC that is taxed as a disregarded entity, so shows up on Schedule C. Do I need to recognize the loan dollars as income for this year, pay the taxes on it, and then declare the interest as it's repaid? Or is there some other mechanism to reduce or defer paying taxes on the amount loaned until future years (which would be ideal).
If there is, I can't figure it out. It looks like I can't deduct the loan principal unless the loan is "worthless" and only then in the year where it becomes so. Do I have this right? Thanks!
