To LLC or not to LLC

Hello!


So, this is the first year I have been a full-time 1099 employee only (freelance). in previous years I had a W-2 to help offset taxes as well as right off’s, but that is not the case this year. If I am going to move forward in future years as a full-time 1099 employee, is it beneficial to do my freelance work under an LLC? Are there other tax breaks or write off’s I can get by doing so? Just curious about the pros and cons
