Summary
On $71,000 of retirement income in Illinois, your total tax is $9,766 (13.75% effective rate), including $7,234 in federal income tax, and $2,532 in Illinois state tax. Quarterly estimate: $2,442.
85.00% of your Social Security benefits ($17,000 of $20,000) is taxable based on your combined income. The IRS uses a formula comparing your other income plus 50% of SS benefits against threshold amounts.
Your federal income tax is $7,234 on $56,000 of taxable income, for an effective rate of 10.19% of gross retirement income.
Illinois adds $2,532 in state income tax on your retirement income, bringing your total tax to $9,766.
Your estimated quarterly payment is $2,442, due in April, June, September, and January. If you don't have taxes withheld from pensions or Social Security, quarterly payments help avoid underpayment penalties.
With 85.00% of your Social Security taxable, consider strategies to reduce combined income — such as Roth conversions in earlier years, timing retirement account withdrawals, or managing other income sources — to potentially lower the taxable portion.
