Contributing to traditional IRA after filing

[hybridtaxguy]

I know I cannot deduct contributions because of my income.  I intend on converting the traditional IRA to a Roth IRA in a backdoor conversion.

I've already filed my taxes for 2022.  Can I contribute the 6,000 yearly max for 2022 even though I filed already?  Would I have to amend?  I realize I'm cutting it down to the wire here, appreciate the help!  Was just reading about backdoor Roth and it seems worth it to contribute to a traditional IRA to covert it.  I'd like to take advantage of this for 2022 but unsure if I'd need to amend or not.

Yes, you can make IRA contributions for 2022 until April 18th.

Yes, you would have to file Form 8606 to report the nondeductible traditional IRA contributions (basis). The basis on line 14 will have to be entered next year on your 2023 tax return. Please see How do I amend my federal tax return for this year?

Please keep in mind the Backdoor Roth only works if all of your traditional/SEP/SIMPLE IRAs are empty (don't have any pre-tax funds). Otherwise, the pro-rata rule applies. 

To enter the nondeductible contribution to the traditional IRA on your 2022 tax return:

1. Open your return
2. Click “Deductions &Credits” on the top
3. Click "I'll choose what to work on"
4. Scroll down to “Traditional and Roth IRA Contributions” and click “Start”
5. Select “traditional IRA”
6. Answer “No” to “Is This a Repayment of a Retirement Distribution?”
7. Enter the amount you contributed
8. Answer “No” to the recharacterized question on the “Did You Change Your Mind?” screen
9. Answer the next questions until you get to “Any Nondeductible Contributions to Your IRA?” and select “Yes” if you had nondeductible contributions before this tax year
10. Enter your basis in the Traditional IRA from your 2021 Form 8606 line 14 (if you had a basis in the prior year)
11. On the “Choose Not to Deduct IRA Contributions” screen choose “Yes, make part of my IRA contribution nondeductible” and enter the amount (if you have a retirement plan at work and are over the income limit it will be nondeductible automatically and you only get a warning and then a screen saying $0 is deductible).

Next year on your 2023 tax return to enter the 1099-R conversion: 

1. Click "Federal Taxes" on the top and select "Wages & Income"
2. Click "I'll choose what to work on"
3. Scroll down and click "Start" next to "IRA, 401(k), Pension Plan (1099-R)" 
4. Answer "Yes" to the question "Did You Have Any of These Types of Income?"
5. Click "I'll Type it Myself"
6. Choose "Form 1099-R, Withdrawal of Money from 401(k) Retirement Plans, Pensions, IRAs, etc."
7. Click "Continue" and enter the information from your 1099-R
8. Answer questions until you get to “What Did You Do With The Money” and choose “I moved it to another retirement account”
9. Then choose “I did a combination of rolling over, converting, or cashing out money.” and enter the amount next to "Amount converted to a Roth IRA account"
10. On the "Your 1099-R Entries" screen click "continue"
11. Answer "yes" to "Any nondeductible Contribution to your IRA?" if you had any nondeductible contributions in prior years.
12. Answer the questions about the basis from line 14 of your 2022 Form 8606 and the value of all traditional, SEP, and SIMPLE IRAs
