@gloriah5200 Thank you for the explanations. I checked the other state tax credit worksheet and it determined that our PA income tax are used as the tax credit to claim on our tax return. I think my question was once the paid PA income tax is used as the credit, can we still claim it as the deduction on the DE Resident schedule A - Itemerized Deductions form? I believe this was 'Enter Amount to Reduce Other State Tax Itemized Deduction' asked for.
Thanks.
