On 20 August 2013, Taïder joined Internazionale on a four-year contract for a €5.5 million transfer fee, plus the loan of Diego Laxalt. Bologna also retained 50% registration as part of the co-ownership deal. He made his debut for the "Nerazzurri" six days later in a 2–0 home victory against Genoa, coming on as a substitute for Ricky Álvarez in the 85th minute. He played 25 times in 2013–14 Serie A for Inter, scoring once in a 7–0 win at Sassuolo on 22 September. On 4 December, in his only Coppa Italia match of the season, he scored a first-half penalty in a 3–2 home win over Serie B club Trapani in the tournament's fourth round.
