Due to France's victory at the UEFA Under-19 championship, the nation qualified for the 2011 FIFA U-20 World Cup, which merited under-20 team appearances for Tafer. After missing the team's opening match of the season against Portugal, he made his under-20 debut in the team's 1–0 win over Montenegro. On 17 May 2011, Tafer scored his first goal for the team in its 3–3 draw with the United States netting France's opening goal.

He made his debut in the competition on 30 July 2011 in the team's 4–1 defeat to the hosts Colombia appearing as a substitute. Tafer is also eligible to represent Algeria and Portugal at international level.

On 24 August 2010, Lyon confirmed that the club had loaned out Tafer to fellow Ligue 1 club Toulouse. The loan was for the entire 2010–11 season and had a buyout option for €4 million. His signing was cited as a replacement for the departed André-Pierre Gignac, who joined Marseille. Tafer was presented to the media by the club on 25 August and was given the number 10 shirt, formerly worn by Gignac.

Despite being on the first-team, Tafer was limited to playing mostly on the club's Championnat de France amateur team appearing in 15 matches scoring five goals, which included a brace against RCO Agde and goals against rivals Saint-Étienne and AS Lyon Duchère. On 24 January 2009, Tafer made his professional debut in the club's Coupe de France match against Concarneau coming on as a substitute in the 75th minute. In the match, he was instrumental in the club's 5th goal after taking a pass and shooting the ball, which went off the post. Teammate Kader Keïta quickly pounced on the rebound and converted the goal. Lyon won the match 6–0. Two weeks later, Tafer made his league debut making a one-minute cameo appearance in a 3–1 victory over Nice. Tafer made two more league appearances being relegated back to the amateur team.

For the 2009–10 season, Tafer's playing time was slightly increased. On 26 September 2009 in his season debut, he scored his first professional goal against Toulouse after appearing in the match as a halftime substitute. The goal drew the match at 1–1 and Lyon won the match after a late second-half goal from Bafétimbi Gomis. Two months later, he assisted on César Delgado's goal in a 2–0 victory over Boulogne.

On 13 June, Tafer converted another hat trick, this time against England in a 4–2 victory. The match was played at Wembley Stadium in front of 15,000 spectators and the victory resulted in the team being presented the Fallenhero Trophy by The Football Association chairman Trevor Brooking. For under-19 duty, Tafer was again called upon by coach Francis Smerecki making his first appearance with the team at the 2009 edition of the Sendaï Cup. Beginning with the team's 2–1 victory over Belgium, Tafer scored a goal in four straight matches. On 7 June 2010, he was named to Smerecki's 18-man squad to participate in the 2010 UEFA European Under-19 Football Championship. In the tournament, he scored the opening goal in the team's 1–1 draw with England. The draw assured the club a place in the semi-final portion of the competition where France defeated Croatia 2–1. In the final, Tafer appeared as a halftime substitute and assisted on the team's opening goal scored by Gilles Sunu. France had been trailing 1–0 prior to the equalizer. France won the match 2–1 following a late goal from Tafer's domestic teammate Alexandre Lacazette. The title is the country's second UEFA Under-19 championship.

Following the 2007–08 season, Tafer signed his first professional contract with Lyon agreeing to a three-year contract until 2011. For the 2008–09 season, he was placed on Lyon's first-team squad and was assigned the 34 shirt, though he was reassigned to the number 29.
