You will have better protection of your personal assets if you keep your business within an LLC. That said, there’s a cost to setting up and maintaining an LLC. The attorney whose advice I received indicated an LLC was a “no-brainer,” but when I considered the cost of set-up and the amount of at-home training I would be doing, it didn’t add up.
When I have more time to develop my training business, I will consider an LLC more seriously. It’s a separate legal entity, requiring its own tax return, a K-1, and then you include the K-1 income on your return. Pretty easy to do (I’m a CPA) but takes some effort.
