How to do I calculate and pay advanced taxes for a Roth IRA conversion I did last month?

I converted 80K from an IRA to an Roth IRA account in July. How to I calculate and pay advanced taxes during this quarter so I don't have to pay a penalty? Do i use IRS tax table or expected effective tax rate to come up with taxes that are due?

How to do I calculate and pay advanced taxes for a Roth IRA conversion I did last month?

So the starting point for this is your taxable income for the full year.  

 

So, let’s start with the tax brackets for 2024:

 

2024 Filing Status: Single, Married Filing Jointly (MFJ), and Qualifying Surviving Spouse (QSS)

Tax Rate

Single Taxable Income Range (2024)

MFJ and QSS Taxable Income Range (2024)

10%

Not over $11,600

Not over $23,200

12%

Over $11,600 but not over $47,150

Over $23,200 but not over $94,300

22%

Over $47,150 but not over $100,525

Over $94,300 but not over $201,050

24%

Over $100,525 but not over $191,950

Over $201,050 but not over $383,900

32%

Over $191,950 but not over $243,725

Over $383,900 but not over $487,450

35%

Over $243,725 but not over $609,350

Over $487,450 but not over $731,200

37%

Over $609,350

Over $731,200

2024 Filing Status: Head of Household (HOH) and Married Filing Separately (MFS)

Tax Rate

HOH Taxable Income Range (2024)

MFS Taxable Income Range (2024)

10%

Not over $16,550

Not over $11,600

12%

Over $16,550 but not over $63,100

Over $11,600 but not over $47,150

22%

Over $63,100 but not over $100,500

Over $47,150 but not over $100,525

24%

Over $100,500 but not over $191,950

Over $100,525 but not over $191,950

32%

Over $191,950 but not over $243,700

Over $191,950 but not over $243,725

35%

Over $243,700 but not over $609,350

Over $243,725 but not over $365,600

37%

Over $609,350

Over $365,600

 

If your filing status is single the standard deduction would be $14,600 for tax year 2024. If married filing jointly it is $29,200 and HOH is $21,900.

 

You would need to see what marginal or marginal tax brackets the $80K conversion being the last incremental money  for the year falls in.   That would be the payment that you should make.  So here is an example:

 

Taxable Income $100K and single.  So while there is a small increment in the 22% tax bracket the vast majority of the $80K is in the 24% tax bracket.  So I would make a payment of $19,200 on or before September 16, 2024 here: IRS Direct Pay

 

Thank you for the question @Kris A 

 

Be well and safe!

How to do I calculate and pay advanced taxes for a Roth IRA conversion I did last month?

Hello Kris A, and thank you for your questions!

You asked,"How do I calculate and pay taxes for a Roth IRA conversion in advance?"

To calculate and pay advanced taxes on a Roth IRA conversion, follow these steps:

  1. Determine the amount of the conversion: The amount you converted is the starting point for calculating your estimated taxes. This amount will be included in your taxable income for the year.

  2. Project your income for the year: Estimate your total taxable income for the year, including the conversion. This will help you determine the correct tax bracket and tax rates that apply to your total income.

  3. Calculate your estimated tax liability: Use the tax rates, tax brackets, and deductions to estimate your tax liability for the year, including the tax due on the conversion.

  4. Calculate your required estimated tax payments: To avoid underpayment penalties, you may need to make quarterly estimated tax payments to the IRS. The required amount is usually 90% of the current year's tax liability or 100% of the prior year's tax liability (110% for high-income earners). You can use Form 1040-ES to calculate your required estimated tax payments.

  5. Make your estimated tax payments: You can make estimated tax payments online, by mail, or by phone using the IRS Electronic Federal Tax Payment System (EFTPS).IRS Payments 

 

Keep in mind that converting from a traditional IRA to a Roth IRA can add  the conversion amount to your taxable income for the year, potentially pushing you into a higher tax bracket. The conversion is then taxed at your ordinary tax rate, which may be adjusted depending on your new tax bracket.

For instance, if you're in the 22% tax bracket and convert $20,000, your taxable income for the year increases by $20,000. If this does not push you into a higher tax bracket, you will owe $4,400 in taxes on the conversion.

However, if your taxable income now exceeds the threshold for the 22% tax bracket, the conversion amount exceeding that threshold will be taxed at a higher rate, which is 24% in 2024.

Also keep in mind that this increase to your overall income, could impact your state tax return, as well, so you may want to consider making a state estimated payment based on your individual state income tax rates, as well.
