CA RDP, RI Single and CA OSTC
A CA RDP return, but for RI each taxpayer files single. This means that the RI returns must be done before OSTC calculation for CA. Then that combined RI taxable income is input as an override for CA Schedule S.
There is no way to get the OSTC and the CA 540 correct. Either one or the other can be correct because the OSTC is automatically calculated based on the State indicators. And the Schedule CA adjustments, to Part I, Section B, Line 5 are also based on the state indicators.
