In the report, the off-shell electromagnetic pion form factors in the Bethe-Salpeter formalism are considered. The separable kernel of the first rank quark-antiquark interaction is used to solve the equation analytically. The half-off-shell pion form factors $F_1$ and $F_2$, which are related to each other by the Ward-Takahashi identity, are calculated. The report shows a comparison of the obtained off-shell form factors and static properties of the pion for two types of kernel functions.
