Are both New York state tax deductions and state sales tax allowed?

I am not a CPA and I think this is the case about taking sales tax as a deduction on federal tax return: you can only take the state sales tax as a federal deduction if you itemize your return. also, most folks take a standard deduction on their federal return and it is more than normal sales tax deduction unless you have a significant amount of sales tax receipts. I also think there is a maximum sales tax deduction based on your adjusted gross income. please have an accountant confirm

Thanks, I think. I do itemize my return and will indeed check w. CPA..also the unfriendly irs.gov site, which I was hoping to avoid.
