Formaldehyde (CH2O) is a polar molecule. ; Kuz'menko, T.e. As a result, they are nonpolar molecules by nature (examples: CO2, SO3).

Agric. Nonpolar compounds will be symmetric, meaning all of the sides around the central atom are identical - bonded to the same element with no unshared pairs of electrons.
