I have a CA resident who worked in NY as a non-resident. Her CA taxes were $10000 and she paid $8000 in NY taxes. When I filed the original return it showed the balance due of $10000 because I had forgotten to put in the Schedule S for credit for taxes paid to NY. I filed an amended return yesterday which included the Schedule S for $8000 and the amended return shows a balance due of $2000. The amended return was accepted yesterday. I just want to be advised that the amended return will supersede the original return and so when client pays the $2000 there should be no problem. I am just concerned that the amended will act over the original return. I have never made such a mistake before and just want to be comforted that the amended will be what CA will consider when processing her returns.
