Sometimes to keep your cash flow moving, you may need to loan your Company money. This is perfectly legitimate, but make sure there is a written promissory note, with some reasonable interest rate, and some reasonable payment schedule.
I would recommend 1+prime as a minimum rate. The prime rate has remained at 3.25% since the end of 2008. Make sure you make timely interest payments and then report this interest as income on your 1040 form.
