I think there is a charge of 2- at the phosphate end of the molecule.
As the molecule is written, there should be no charge. However, whenever I have seen the molecule displayed, there are no hydrogens attached to the ogygens of the phosphate group. If there were no hydrogens, there would be a -2 charge.
Additionally, the article says that the molecule is created from Carbon dioxide. I think it's actually created using bicarbonate, or HCO3-. I'm not sure enough to edit the page though. Can anyone back this up?

I agree with pmont, that in physiological conditions there should be no Hs on the oxygens in the phosphate group; they are fairly acidic and thus not present at pH 7.2-7.4. So in the body, carbamoyl phosphate has a [-2] charge.
I'd also add that the enzyme that synthesizes carbamoyl phosphate is carbamoyl phosphate synthETase, not synthase. As stated in the article, it uses ATP so it's imporant to differentiate enzymes that use/don't use ATP as synthetases/synthases respectively. - Sam
