Basics
What is an IRA?
An Individual Retirement Account (IRA) is a tax-advantaged savings account you open directly with a financial institution - not through an employer. The government gives you a tax benefit now (Traditional IRA deduction) or later (Roth IRA tax-free withdrawals) to encourage long-term retirement saving. In 2026 you can contribute up to $7,000 per year ($8,000 if you are 50 or older).
What is the main difference between a Traditional IRA and a Roth IRA?
Timing of the tax break. With a Traditional IRA you may deduct contributions from your income today and pay tax when you withdraw in retirement. With a Roth IRA you contribute after-tax money, and qualified withdrawals in retirement are completely tax-free including the growth. The right choice depends on whether you expect your tax rate to be higher now or in retirement.
Use the break-even calculator →Who can open an IRA?
Any US taxpayer who has earned income for the year can contribute to an IRA. Earned income means wages, salary, tips, self-employment income, or alimony. It does NOT include interest, dividends, rental income, Social Security, or pension payments. There is no minimum age and no maximum age. You must contribute no more than your earned income for the year, up to the annual limit.
Can I have both a Traditional IRA and a Roth IRA?
Yes. You can own both types simultaneously and contribute to both in the same year. However, the $7,000 annual limit ($8,000 if 50+) applies across all your IRAs combined. You could put $3,500 in a Traditional and $3,500 in a Roth, or any other split, but the total cannot exceed $7,000.
2026 contribution limits →How do I open an IRA?
Open directly with a broker or financial institution online. The process takes 10 to 15 minutes. You will need your Social Security number, bank account for funding, and employer information. The five most popular providers are Fidelity, Charles Schwab, Vanguard, Robinhood, and M1 Finance. All offer $0 minimum and $0 annual fees.
Compare IRA providers →Limits and Eligibility
What are the IRA contribution limits for 2026?
In 2026 you can contribute up to $7,000 if you are under age 50, or $8,000 if you are age 50 or older (the $1,000 catch-up contribution). This is the combined limit across all Traditional and Roth IRAs you own. The deadline is April 15, 2027. Source: IRS Rev. Proc. 2025-32.
2026 limits in detail →How many IRAs can I have?
There is no limit on the number of IRA accounts you can own. Many people have multiple IRAs accumulated over years at different brokers. However, the annual contribution limit ($7,000 or $8,000) applies to the total across ALL your IRAs combined, regardless of how many accounts you have.
Can a non-working spouse contribute to an IRA?
Yes, through a spousal IRA. If you file taxes jointly and your spouse has earned income, the non-working spouse can contribute to their own IRA up to the annual limit based on the working spouse's earnings. This means a married couple can contribute up to $14,000 per year combined ($16,000 if both are 50+).
Spousal IRA rules →What happens if I contribute more than the limit?
Over-contributions are subject to a 6% excise tax per year on the excess amount for every year the excess remains in the account. To avoid the penalty, withdraw the excess contribution plus any earnings attributable to it before your tax-filing deadline (including extensions). Use IRS Form 5329 to report and pay the penalty if you do not fix it in time.
Tax Treatment
Are Roth IRA withdrawals ever taxable?
Qualified Roth IRA distributions are completely tax-free. To be qualified, two conditions must both be met: (1) you must be at least age 59.5, and (2) at least 5 years must have passed since your first Roth IRA contribution (this 5-year clock starts January 1 of the year you made your first contribution). Roth IRA contributions (not earnings) can always be withdrawn tax-free and penalty-free at any age.
Full withdrawal rules →Is a Traditional IRA taxed twice?
No. If you took a deduction when you contributed, you pay tax only once - when you withdraw. If you made non-deductible (after-tax) contributions and tracked your basis on Form 8606, those specific dollars are not taxed again on withdrawal. Only the growth and the pre-tax contributions are taxed at withdrawal. Proper Form 8606 filing is essential to avoid double taxation.
What tax form do I use for IRA contributions?
For Roth IRA contributions you do not need to file anything - they are not deductible and are made from after-tax dollars. For deductible Traditional IRA contributions, report on Schedule 1 of Form 1040 (line for IRA deduction). For non-deductible Traditional IRA contributions, you MUST file Form 8606 to track your cost basis. Failing to file Form 8606 every year can result in double taxation later.
Does contributing to an IRA reduce my taxable income?
Only a deductible Traditional IRA contribution reduces your taxable income. Roth IRA contributions do not. Whether your Traditional IRA contribution is deductible depends on your income, filing status, and whether you or your spouse are covered by a workplace retirement plan. In 2026 the deduction phases out at $79,000 to $89,000 MAGI for single filers covered by a workplace plan.
Traditional IRA deductibility limits →Conversions and Backdoor
What is a Roth conversion?
A Roth conversion moves money from a Traditional IRA (or other pre-tax retirement account) into a Roth IRA. You pay ordinary income tax on the converted amount in the year of conversion. After conversion, the money grows tax-free and qualified withdrawals are tax-free. Conversions are irrevocable since 2018 - you cannot undo them. The best time to convert is when your tax rate is temporarily low.
Conversion strategy guide →Is the backdoor Roth still legal in 2026?
Yes. The backdoor Roth IRA - contributing to a non-deductible Traditional IRA then converting it to Roth - remains legal under current law. The Build Back Better Act proposals to eliminate it were not enacted. Congress has implicitly endorsed the strategy in multiple legislative conference reports. There is no guarantee about future tax law changes, but it is fully legal as of April 2026.
Backdoor Roth step-by-step →What is the pro-rata rule for backdoor Roth?
If you have any pre-tax IRA balance (from deductible contributions or rollover from a 401k) on December 31 of the conversion year, the IRS treats all your Traditional IRA money as a single pool. Your conversion will be partially taxable in proportion to the pre-tax percentage. For example: $63,000 pre-tax + $7,000 after-tax = 90% pre-tax. Converting $7,000 means $6,300 is taxable. Solution: roll pre-tax balances into your employer 401k before the conversion.
Pro-rata rule explained →Can I recharacterize (undo) a Roth conversion?
No. Since the Tax Cuts and Jobs Act of 2018, Roth conversions cannot be recharacterized (reversed). Once you convert from Traditional to Roth, it is permanent. You can still recharacterize a Roth IRA contribution as a Traditional IRA contribution (or vice versa) for the same tax year, but you cannot undo a conversion.
Withdrawals and RMDs
When can I withdraw from an IRA without penalty?
Age 59.5 is the main threshold for penalty-free withdrawals from both Traditional and Roth IRAs. Before 59.5, a 10% early withdrawal penalty applies unless an exception applies (disability, first-time home purchase up to $10,000, higher education, medical expenses exceeding 7.5% of AGI, and several others under SECURE Act 2.0). Roth IRA contributions - but not earnings - can be withdrawn penalty-free at any age.
All withdrawal exceptions →What is the Roth IRA 5-year rule?
There are actually two separate 5-year rules. The account clock: to withdraw Roth earnings tax-free, your Roth IRA must have been open at least 5 years AND you must be 59.5 or older (or meet another qualifying exception). The conversion clock: each Roth conversion has its own 5-year clock before you can withdraw that converted amount penalty-free if you are under 59.5. The two clocks are completely independent.
Both 5-year rules explained →When do Required Minimum Distributions (RMDs) start?
Under SECURE Act 2.0, the RMD start age depends on your birth year. If you were born in 1951 through 1959, RMDs start at age 73. If you were born in 1960 or later, RMDs start at age 75. Roth IRAs have NO RMDs during the owner's lifetime - a major advantage for people who do not need the income and want to leave tax-free money to heirs.
RMD rules and calculation →Do Roth IRAs have Required Minimum Distributions?
No. Roth IRAs are exempt from RMDs during the account owner's lifetime. This is one of Roth's most significant advantages for wealth accumulation and estate planning. When a Roth IRA is inherited, non-spouse beneficiaries are subject to the 10-year rule, but because there are no RMDs, they can let the account grow tax-free and take the entire balance in year 10.
Inherited Roth IRA rules →What is the penalty for missing an RMD?
Under SECURE Act 2.0, the penalty for missing an RMD was reduced from 50% to 25% of the shortfall. The penalty is further reduced to 10% if you correct the missed RMD within 2 years and file IRS Form 5329. This means missed RMDs are always fixable - act quickly, take the missed distribution, and file the correction.
RMD rules →Employer Plans
Can I contribute to both a 401(k) and an IRA in the same year?
Yes. A 401k and an IRA are completely separate accounts with separate limits. In 2026 you can contribute up to $23,500 to your 401k ($31,000 if 50+) AND up to $7,000 to an IRA ($8,000 if 50+). Contributing to a 401k does not prevent you from contributing to an IRA - but it may reduce or eliminate the deductibility of a Traditional IRA contribution if your income is above certain thresholds.
IRA vs 401k order of operations →Does having a 401(k) affect my IRA deduction?
Yes, if you are covered by a workplace retirement plan (including a 401k, 403b, SIMPLE IRA, SEP-IRA, or pension), your Traditional IRA deduction phases out at lower income levels. In 2026 the phase-out is $79,000 to $89,000 MAGI for single filers, and $126,000 to $146,000 for married filing jointly when covered by a workplace plan. Above those limits you can still contribute to a Traditional IRA (non-deductible), making the backdoor Roth relevant.
Deductibility phase-out tables →Does the $145,000 mandatory Roth catch-up rule apply to IRAs?
No. SECURE Act 2.0 Section 603 requires workers who earned more than $145,000 (indexed) in the prior year to make their catch-up contributions as Roth - but this rule ONLY applies to 401k, 403b, and governmental 457b workplace plans. IRA catch-up contributions ($1,000 extra for age 50+) are unaffected. You can still make Traditional or Roth IRA catch-up contributions regardless of your income level. Effective starting 2026.
Catch-up contribution rules →Can I roll a 401(k) into an IRA?
Yes. When you leave an employer you can roll your 401k balance into a Traditional IRA (pre-tax to Traditional) or a Roth IRA (pre-tax to Roth, but you pay income tax on the converted amount). Rolling to an IRA gives you more investment choice and often lower fees. However, rolling into a Traditional IRA increases your pre-tax IRA balance, which can complicate the backdoor Roth pro-rata calculation. Consider rolling to your new employer's 401k instead if you plan to do backdoor Roth conversions.
Pro-rata rule and rollovers →Other
What happens to my IRA if I move to a different state?
Your IRA itself is unaffected. The federal tax rules are the same in every state. What changes is the state income tax on withdrawals. Some states (including Florida, Texas, Nevada, Washington, Wyoming, South Dakota, and Alaska) have no income tax and therefore no tax on IRA withdrawals. If you are doing Roth conversions, timing them after you establish residency in a lower-tax state can save significant money.
State tax and Roth conversions →Can I contribute to an IRA while collecting unemployment?
Only if you have other earned income. Unemployment benefits are not earned income for IRA purposes. If you have no earned income at all during the year, you cannot contribute to an IRA that year. If you have some earned income (freelance work, part-time wages) but less than $7,000, you can contribute up to your earned income amount.
What are the basic rules for an inherited IRA?
Under the SECURE Act (effective for deaths in 2020 and later), most non-spouse beneficiaries must empty an inherited IRA within 10 years. The 10-year deadline is December 31 of the 10th year after the original owner's death. Annual RMDs are also required during the 10 years if the original owner had already started RMDs. Spouses have more flexibility and can roll the inherited IRA into their own IRA. Eligible Designated Beneficiaries (minor children, disabled individuals, those not more than 10 years younger than the deceased) can still stretch distributions over their lifetime.
Inherited IRA rules in detail →Is a SEP-IRA the same as a Traditional IRA?
They are similar but not identical. A SEP-IRA is a Simplified Employee Pension IRA used by self-employed individuals and small business owners. Contributions are made by the employer (even if you are self-employed). In 2026 SEP-IRA contributions can be up to 25% of compensation or $70,000, whichever is less - much higher than the regular $7,000 IRA limit. Distributions are taxed the same as Traditional IRA distributions. You can hold both a SEP-IRA and a Traditional or Roth IRA simultaneously.
