Conquest Racing announced that Tagliani would return as a full-time driver for the 2009 season. However, the team ultimately concentrated on road and street course races after the Indianapolis 500; ninth place in Toronto proved his best result. Tagliani left Conquest Racing after the 2009 Rexall Edmonton Indy race in Edmonton, Alberta, Canada. It was announced on August 28, 2009, that Tagliani had signed a four-year deal with an option for a fifth year to drive for start-up FAZZT Race Team in the IZOD IndyCar Series beginning in 2010. After a successful 2010 campaign with Tagliani, FAZZT Race Team was looking forward to an even more successful 2011 season, along with the possible expansion on the grid with a second entry. However, the team was purchased by Sam Schmidt on March 1, 2011, and was absorbed into Sam Schmidt Motorsports. Tagliani was retained, along with all sponsors, for a full-time entry during the 2011 season, racing alongside his new teammates Townsend Bell, Wade Cunningham, and Jay Howard. In 2011, for the 100th anniversary of the first running of the Indianapolis 500, Tagliani qualified on the pole position with a four-lap average of 227.472 mph, besting Scott Dixon in the last run of the day. Unfortunately for Tagliani, he would run wide in turn 4 on lap 147 and make contact with the outside wall, inflicting damage upon the car which would force him to retire from the race the following lap. To date, Tagliani's best finish in the Indianapolis 500 is tenth, which he achieved in 2010 while driving for FAZZT Race Team. His best performance was arguably the 2016 event when he charged hard from 33rd starting position to lead 11 laps, matching a record set by Tom Sneva in 1980. NASCAR Xfinity and Truck Series Tagliani has run selected races in the NASCAR Xfinity Series since 2009. That year he entered the Montreal and Phoenix rounds with Pat MacDonald. He drove at Montreal in 2011 for Team Penske and 2012 for Steve Turner. He did not enter any race in 2013. In 2014, Tagliani announced that he would drive in two races in the series for Team Penske. At Road America for the Gardner Denver 200, Tagliani won the pole position driving Penske's No. 22. Tagliani nearly won his first NNS race leading the second half. However, it was questionable with 10 laps to go if Tagliani had
