Of course there is also a formal future tense in Italian. To form the simple future (futuro semplice), you drop the final -e of the infinitive and add the endings -ò, -ai, -à, -emo, -ete, -anno. Only verbs ending in -are have further changes: they replace the -a- in the infinitive with an -e-.
Take a look at the following table which shows the conjugations for regular verbs ending in -are, -ere, and -ire.
