Choice of Business Entity
My wife has an established service business which we have been operating as a "Sole Proprietorship" for several years. For both liability and tax reasons, I feel the time has come to either Incorporate or create an LLC. The liability reasons are obvious but the tax reasons are a bit more complicated. One major goal is to reduce her self employment tax (which we all know is a lousy investment) so that we can take more responsibility for our own retirement. I'm told an S-Corp is the best choice for this type of strategy. Now I find this new entity called an LLC. According to the IRS, an LLC can choose to file as a Schedule C, a Partnership, an S-Corp, a C-Corp, or any other type of return. So what is the difference? Should I incorporate and file an 1120S? Or should I create an LLC and file an 1120S anyway? In my state (New Hampshire) there is no difference in filing fees or administrative burden between an LLC and a Corporation. If an LLC can file any federal tax form it chooses, then what is the advantage? Conversely, if I want to file as an S-Corp, why not just become an S-Corp?
Thank you all so much in advance for your time and advice.
