The charges formally reside on the oxygen atoms, as we would expect for this strongly electronegative atom.

Explanation:

There are $5 + 4 \times 6 + 3 = 32 valence electrons$ $5+4xx6+3=32" valence electrons"$ for $P O_{4}^{3 -}$ $PO_4^(3-)$ , and a formal Lewis structure of $O = P {(- O^{-})}_{3}^{-}$ $O=P(-O^-)_3$ is proposed. What is your prediction with respect to the structure of the phosphate ion?

Note that when we titrate phosphporic acid $H_{3} P O_{4}$ $H_3PO_4$ with sodium hydroxide, we get mainly $H P O_{4}^{2 -}$ $HPO_4^(2-)$ at the endpoint in aqueous solution.
