Part — Instruction 8606 — Instructions for Form

Line 1 If you used the IRA Deduction Worksheet in the Form 1040 instructions or as referred to in the Form 1040-NR instructions, subtract line 12 of the worksheet (or the amount you chose to deduct on Schedule 1 (Form 1040), line 20, if less) from the smaller of line 10 or line 11 of the worksheet. Enter the result on line 1 of Form 8606. You can’t deduct the amount included on line 1.

If you used the worksheet Figuring Your Reduced IRA Deduction for 2025 in Pub. 590-A, enter on line 1 of Form 8606 any nondeductible contributions from the appropriate lines of that worksheet.

If you didn’t have any deductible contributions, you can make nondeductible contributions up to your contribution limit (see Overall Contribution Limit for Traditional and Roth IRAs , earlier). Enter on line 1 of Form 8606 your nondeductible contributions.

Include on line 1 any repayment of a qualified reservist distribution.

Don’t include on line 1 contributions that you had returned to you with the related earnings (or less any loss). See Return of IRA Contributions, earlier.

Line 2 Generally, if this is the first year you are required to file Form 8606, enter -0-. Otherwise, use the Total Basis Chart to find the amount to enter on line 2.

However, you may need to enter an amount that is more than -0- (even if this is the first year you are required to file Form 8606) or increase or decrease the amount from the chart if your basis changed because of any of the following.

You rolled over any nontaxable portion of your qualified retirement plan to a traditional IRA that wasn’t previously reported on Form 8606, line 2. Include the nontaxable portion on line 2.

Line 4 If you made contributions to traditional IRAs for 2025 in 2025 and 2026 and you have both deductible and nondeductible contributions, you can choose to treat the contributions made in 2025 first as nondeductible contributions and then as deductible contributions, or vice versa.

Example. You made contributions for 2025 of $2,000 in May 2025 and $2,000 in January 2026, of which $3,000 is deductible and $1,000 is nondeductible. You choose $1,000 of your contribution in 2025 to be nondeductible. You enter the $1,000 on line 1, but not line 4, and it becomes part of your basis for 2025.

Although the contributions to traditional IRAs for 2025 that you made from January 1, 2026, through April 15, 2025, can be treated as nondeductible, they aren’t included in figuring the nontaxable part of any distributions you received in 2025.

Line 6 Enter the total value of all your traditional IRAs as of December 31, 2025, plus any outstanding rollovers. A statement should be sent to you by January 31, 2026, showing the value of each IRA on December 31, 2025. However, if you recharacterized any amounts originally contributed, enter on line 6 the total value, taking into account all recharacterizations of those amounts, including recharacterizations made after December 31, 2025. For purposes of line 6, a rollover is a tax-free distribution from any traditional IRA that is contributed to another traditional IRA. The rollover must be completed within 60 days after receiving the distribution from the first IRA. An outstanding rollover is generally the amount of any distribution received in 2025 after November 1, 2025, that was rolled over in 2026, but within the 60-day rollover period. A rollover between a traditional SIMPLE IRA and a qualified retirement plan or an IRA (other than a traditional SIMPLE IRA) can only take place after your first 2 years of participation in the traditional SIMPLE IRA. See Pub. 590-A for more details.

You had a return of excess traditional IRA contributions (see Return of Excess Traditional IRA Contributions , earlier).
Incident to divorce, you transferred or received part or all of a traditional IRA (see the last bulleted item under Line 7 , later).
