Il faut que j'aille à la banque. Il me faut aller à la banque. Falloir is used: With the infinitive Il faut arriver à l'heure. (It is necessary to arrive on time or One has to arrive on time or One must arrive on time.) Il ne faudrait pas faire cela. (One shouldn't do that.) With the infinitive and an indirect object Il me faut étudier. (I have to study.) Il lui fallait travailler. (He [she] had to work.) With que followed by the subjunctive Il faudra que je parte.
