Taylor struck on 35 and 66 minutes to seal Pompey's berth in the next round although they had to sweat it out late on after Andy Parton pulled one back for Iron.
A relatively quiet first half saw few chances, with Teddy Sheringham testing Scunthorpe keeper Tom Evans with a well-struck free kick from 25 yards.
Pompey then took the lead on 35 minutes when Evans palmed away Sheringham's close range shot and Matthew Taylor was there to sweep the rebound home right-footed from six yards.
Brian Laws' side did push forward after the goal and although they tested the home defence down the wings, they were unable to trouble Shaka Hislop.
The second half was even and the Division Three side held their own until Taylor grabbed his second goal of the game on 66 minutes.
Sheringham did well on the edge of the box to help the ball on and Taylor arrived to fire the ball past Evans on the half volley - again with his right foot.
The game looked all over but the home side seemed to relax too much, and Scunthorpe grew in stature and gradually applied more pressure.
Peter Beagrie had a free kick clawed away by Hislop and Steve Torpey headed just over the bar from the resulting corner kick.
Harry Redknapp's men failed to heed the warning and substitute Andy Parton volleyed in the closing stages to give the away fans a glimmer of hope.
Scunthorpe threw everything at Portsmouth in the dying minutes but failed to create another opening and Pompey held on to claim a place in the fifth round of the cup.
