I live in PA. Should I consider forming aLLC else where? Is there any benefits?
There are tax benefits that vary across the states. I recommend working with a very good vetted CPA. Find the best one that you can afford because, in the end, the CPA can save you thousands in taxes by setting the foundation for the corporation correctly. I have had a few corporations choose Delaware for a verity of different reasons, not just tax reasons. https://www.legalzoom.com/articles/incorporating-in-delaware-advantages-and-disadvantages
Some states have lower tax or no taxes. Nevada is a popular place for people to incorporate.
Keep in mind while I know a LOT about the law (having worked in journalism and as a coach/consultant for over 20 years) I am not a lawyer.
However, I can help walk you through some processes of forming your business — such as deciding your strategies in many areas (like marketing) and getting free publicity.
I would love to help you further, so I hope you'll book a short follow-up call soon.
