Hi Antoinette, you’re wise to consider this *before* making the move! The good news is that there are definitely great options for self-employed/small bizness owners when it comes to retirement. In my case, I have my own consulting practice and I set up a solo 401k. It works exactly the same as an employer plan – there are individual contributions and employer contributions – except, of course, that it’s ME in both of those cases! The contribution limits are generous – for the individual it’s $18,000 and as an employer, it’s up to 20%ish of net profit (I say “ish” because there’s some math to do to figure out the exact amount). The total combined contribution is in the $50,000 range. It’s actually an amazing way to sock it away (even catch up, like I had to) because of those generous contribution limits.
Vanguard has a really good comparison on their site: https://investor.vanguard.com/what-we-offer/small-business/compare-plans?Link=facet
Good luck!
