Should I start my LLC now?================>>I assume LLC means SMLLC, then you do not need to start your LLC UNLESS you are actually engaged in business activities.
Or should I just wait until January for tax purposes?============>>>>I think so; you need to start your SMLLC when you actually get business contracts with your clients in 2016. As a disregarded for tax purposes, you usually need to report all of the LLC’s business activity on a personal tax return by calculating each net profit or loss on the Sch C attachment to IRS Form 1040. However, you need not file a Sch C/SE UNLESS the net taxable earnings for the business are $400 or more. Therefore, no tax reporting requirements exist for inactive SMLLC.
