An IRA affects your tax return in three places: the contribution you report for the year, the growth inside the account (which you don’t report at all), and any withdrawals, conversions, or penalties that flow through as income or additional tax. Whether the account helps or hurts a given year’s return depends on the type—traditional or Roth—and on income, age, and what you did with the money.
What Contributing Does to This Year’s Return
Traditional IRA: A Deduction on Schedule 1
A traditional IRA contribution can be subtracted from gross income as an adjustment on Schedule 1 of Form 1040, which lowers your adjusted gross income before tax rates apply.1Internal Revenue Service. Instructions 1040 (2025) The 2026 contribution limit is $7,500, or $8,600 if you’re 50 or older.2Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 A $7,500 contribution at the 22% bracket saves $1,650 on the federal return.
Whether the full deduction lands depends on workplace retirement plan coverage. If neither you nor your spouse is covered, every dollar you contribute is deductible regardless of income. When a workplace plan is in the picture, 2026 phase-outs apply:
- Single filer covered by a workplace plan: $81,000 to $91,000
- Married filing jointly, contributing spouse covered: $129,000 to $149,000
- Married filing jointly, contributing spouse not covered but other spouse is: $242,000 to $252,000
- Married filing separately, covered by a workplace plan: $0 to $10,000
Below the lower number, the full deduction applies. Above the upper number, none of it. In between, the IRS reduces it proportionally.2Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 You can still contribute above the phase-out; you just won’t get the deduction, and those nondeductible dollars need to be tracked (see Form 8606 below).
Roth IRA: No Deduction, but Watch the Income Limits
Roth contributions are made with money that has already been taxed, so nothing is deducted on the return.3Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs Eligibility to contribute at all depends only on income, not on workplace plan coverage. For 2026, single filers can make full Roth contributions with a modified adjusted gross income below $153,000, phasing out entirely at $168,000. Married filing jointly phases out between $242,000 and $252,000.2Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Contributing above the ceiling creates an excess contribution problem, covered later.
The Saver’s Credit
Lower- and moderate-income taxpayers may qualify for the Retirement Savings Contributions Credit on top of any deduction. It’s a dollar-for-dollar credit worth 50%, 20%, or 10% of the first $2,000 contributed ($4,000 for joint filers), tiered by AGI.4Internal Revenue Service. Retirement Savings Contributions Credit (Saver’s Credit) For 2026, single filers at $24,250 AGI or less get the 50% rate, and the credit disappears above $40,250 single, $60,375 head of household, and $80,500 married filing jointly.5Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs The credit applies to both traditional and Roth contributions, so a Roth funder who gets no deduction can still shrink the tax bill through the credit.
Growth Inside the Account Doesn’t Hit the Return
Once money is inside an IRA, dividends, interest, capital gains, and rebalancing trades generate no annual tax reporting. In a traditional IRA, that growth is tax-deferred and will be taxed on withdrawal. In a Roth, qualified distributions leave the growth untaxed permanently. Either way, nothing about ordinary investment activity inside the account appears on your 1040.
Withdrawals: Where the Return Feels the Account Most
Traditional IRA Distributions
Every dollar withdrawn from a traditional IRA counts as ordinary income at your federal rate for that year.6Internal Revenue Service. Retirement Plans FAQs Regarding IRAs Distributions (Withdrawals) A $30,000 withdrawal in the 22% bracket generates $6,600 of federal tax. This applies whether the underlying dollars came from deductible contributions, nondeductible contributions, or growth, though nondeductible basis gets sorted out through Form 8606 so it isn’t taxed twice. Large single-year withdrawals can push you into a higher bracket, so spreading distributions across years often matters.
Roth IRA Qualified Distributions
Qualified Roth withdrawals are tax-free. Two conditions must both hold: the account must have been open at least five tax years, and you must be at least 59½, permanently disabled, or using up to $10,000 for a first home.6Internal Revenue Service. Retirement Plans FAQs Regarding IRAs Distributions (Withdrawals) Your original Roth contributions can always be withdrawn without tax or penalty regardless of age or account age; the five-year rule and age test govern only the earnings.
Required Minimum Distributions
Traditional IRA owners must begin taking annual withdrawals at age 73 (born before 1960) or age 75 (born 1960 or later, starting in 2033).7Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs The first RMD is due by April 1 of the year after you reach the applicable age; subsequent ones must come out by December 31.8Federal Register. Required Minimum Distributions Skipping one triggers a 25% excise tax on the amount that should have been withdrawn, reduced to 10% if corrected within two years.9Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) Roth IRAs have no RMD during the original owner’s lifetime.
Early Withdrawals and the 10% Penalty
Taking money out before age 59½ generally adds a 10% additional tax on top of ordinary income tax.10Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts For traditional IRAs, the whole withdrawal is exposed. For Roth IRAs, the penalty and income tax reach only earnings pulled out before the qualified-distribution requirements are met; original contributions come out first, clean.
The code lists exceptions where the 10% penalty doesn’t apply:11Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
- First-time home purchase, up to $10,000 (IRA only)
- Qualified higher education expenses for you, your spouse, or dependents (IRA only)
- Total and permanent disability
- Substantially equal periodic payments calculated using IRS-approved methods
- Unreimbursed medical expenses above 7.5% of AGI
- Health insurance premiums while unemployed, after receiving unemployment compensation for at least 12 weeks (IRA only)
- Birth or adoption expenses, up to $5,000 per child
- Federally declared disaster, up to $22,000
An exception waives the penalty, not the income tax. Traditional IRA dollars still land on the return as ordinary income.
The 60-Day Rollover Trap
If you take an indirect rollover (a check made out to you), you have 60 days to redeposit it into another IRA. Miss the deadline and the whole amount is treated as a taxable distribution, plus the 10% penalty if you’re under 59½.12Internal Revenue Service. Retirement Plans FAQs Relating to Waivers of the 60-Day Rollover Requirement You’re also limited to one indirect IRA-to-IRA rollover per 12-month period across all your IRAs; direct trustee-to-trustee transfers and Roth conversions don’t count toward that limit.13Internal Revenue Service. 14Office of the Law Revision Counsel. 26 USC 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts The 6% applies every year the excess stays in the account. A $2,000 excess left in place costs $120 a year until corrected. To avoid the penalty entirely, withdraw the excess plus any earnings on it by your tax-filing deadline including extensions.
Prohibited Transactions
Certain uses of an IRA are banned outright: borrowing from it, pledging it as loan collateral, selling property to it, or using its funds for personal-use property.15Internal Revenue Service. Retirement Topics – Prohibited Transactions The rules also cover transactions with “disqualified persons,” including a spouse, parents, children, and controlled business entities. The penalty is unusually harsh: the IRA loses its tax-advantaged status as of January 1 of the year of the violation, and the full fair market value is treated as a distribution on that date, taxable as ordinary income, with the 10% penalty stacked on if you’re under 59½.
Form 8606: Tracking Nondeductible Contributions
Any traditional IRA contribution you can’t deduct—whether income put you past the phase-out or you chose not to claim the deduction—should be reported on Form 8606 with that year’s return.16Internal Revenue Service. About Form 8606, Nondeductible IRAs The form establishes your “basis,” the after-tax dollars already inside the account. Without it, the IRS has no record you paid tax on those contributions, and the same dollars will be taxed again on withdrawal.
The direct penalty for not filing Form 8606 is $50, and $100 for overstating a nondeductible amount.17Office of the Law Revision Counsel. 26 USC 6693 – Failure to Provide Reports on Certain Tax-Favored Accounts The real cost is the double taxation years later when basis can’t be reconstructed.
Roth Conversions on the Return
Moving money from a traditional IRA into a Roth IRA is allowed at any income level, but the converted amount is added to that year’s ordinary income.18Internal Revenue Service. Retirement Plans FAQs Regarding IRAs Convert $50,000 and $50,000 lands on the return as taxable income. The conversion itself doesn’t trigger the 10% early withdrawal penalty, but each conversion carries its own five-year clock; withdrawing the converted amount within five years while under 59½ brings the 10% penalty on the taxable portion. Conversions are reported on Form 8606.16Internal Revenue Service. About Form 8606, Nondeductible IRAs
How Traditional IRA Withdrawals Affect Social Security Taxes
For retirees drawing Social Security, traditional IRA withdrawals can drag benefits into taxable territory. The IRS uses “combined income” (AGI plus nontaxable interest plus half of annual Social Security benefits) to decide how much of the benefit is taxed. Traditional IRA distributions raise AGI and therefore combined income. Federal thresholds:
- Single filers below $25,000 combined income: benefits are not taxed
- Single filers between $25,000 and $34,000: up to 50% of benefits taxable
- Single filers above $34,000: up to 85% taxable
- Married filing jointly below $32,000: benefits not taxed
- Married filing jointly between $32,000 and $44,000: up to 50% taxable
- Married filing jointly above $44,000: up to 85% taxable
Roth distributions are excluded from AGI, so they don’t feed combined income. A $30,000 traditional withdrawal can push up to 85% of Social Security into the taxable column; the same $30,000 from a Roth doesn’t move the calculation.
Inherited IRAs: Different Rules
If you’re filing a return that includes distributions from an inherited IRA, the tax treatment tracks the account type but the timing rules are separate. Traditional inherited IRA distributions are ordinary income to the beneficiary. A surviving spouse can roll the account into their own IRA and treat it as always theirs. Most non-spouse beneficiaries of account holders who died in 2020 or later must empty the account by the end of the 10th year after the year of death.19Internal Revenue Service. Retirement Topics – Beneficiary Inherited Roth contributions come out tax-free; earnings may be taxable if the original Roth was open fewer than five years at the owner’s death.
