The 2008 and prior year Form 5500 datasets are complete and will not change. Any filers submitting delinquent Form 5500s for plan years prior to 2009 will use the current form available on EFAST2 (see EFAST2 FAQ 4). The data for that filing will be included in the current form dataset. EFAST2 offers a 5500 Version Selection Tool to assist filers in determining which version of the Form 5500 series to submit.
