From any formation achievable by a fractional tag: All walk straight ahead until in a completed double pass thru formation.
NOTE: Although the original idea was for dancers to have reached the starting formation by an actual fractional tag call, in practice many callers use Complete Your Tag from formations that have been reached by calls other than Tag calls; e.g., Heads Pass the Ocean (into "one quarter tag formation") and then Complete Your Tag (into completed double pass thru formation).
