I am retired and withdrew $50,000 in Jan 2024 on my IRA account and withheld $3,000 from 2023 IRS refund as estimate tax. I delayed my SS benefit and my spouse is on SS benefit. My estimate federal tax is around $3,700 based on our current income (married join filing) of $67,000. I plan to withdraw another $30,000 (lowest bracket for income tax benefit) on my IRA in Dec 2024. I thought I can make payment in 4th quarter that due in Jan 2025.
I read on the internet that the IRS will spread all my 2024 income ($97,000) into 12 months instead. In that case I will miss the estimate tax on second and third quarters. My estimate federal tax will be around $7,300 for $97,000 income. My estimate tax due on each quarter will be $1825 that the $3,000 should cover the first and possible second quarter without penalty. I read the penalty will be around 8% (which is $1825x2x8%=$292)
Is my assumption correct and what is your advice? My option is not withdraw another $30,000. Thank you.
