ROTH Conversion and Avoiding State Tax payments

Hello All, 

 

My income is bit less than 100k a year and filling returns as MFJ. I am non citizen-resident alien. 

I have contributed 12,000 to T-IRA last year (2022) for me and spouse.  This entire 12k are pre-tax / deductible funds. 

 

Q1: I know, I can contribute to ROTH directly.  But for this year (2023), I am planning to contribute 13k to T-IRAs and immediately recharacterize it to ROTH.  So that I can claim 13k as deductible funds in Federal taxes and add it back to my income via form 1099-R.   My understanding is - then I will avoid IL state taxes on these 13k, as state does not tax retirement income - Refer this link

Is my understanding correct ? 

 

Q2: Since I have never contributed to T-IRA - non deductible / after tax  funds, there should not be any complications wrt pro-rata/ aggregation rules from T-IRA side.  But wanted to confirm the same. 

 

Thanks in advance. 

 

Thanks,
