Summary
On $71,000 of retirement income in Hawaii, your total tax is $10,223 (14.40% effective rate), including $6,790 in federal income tax, and $3,433 in Hawaii state tax. Quarterly estimate: $2,556.
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 $6,790 on $54,900 of taxable income, for an effective rate of 9.56% of gross retirement income.
Hawaii adds $3,433 in state income tax on your retirement income, bringing your total tax to $10,223.
Your estimated quarterly payment is $2,556, 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.
