Well only you can tell if doing a rollover is best for you. IRA’s can give you more investment options and less fees. So, there are some advantages.
If you are doing a 403b rollover to IRA the first step is to call the company that hosts your 403b plan and see what their rules are. Do they have any fees or paperwork that you should be aware of? Are you even able to rollover your plan? If you are still employed with the company you might not be able to.
Once you figured that out it is time to worry about the IRA. If you already have an IRA you can call them and get the paperwork for a rollover. You may want to also figure out any rules or fees that they may charge.
If you want to get rid of all the hassles that come with traditional IRA rollovers remember to do a “direct rollover” so that the money is transferred to your plan and not to you directly.
