Roth IRA Guide 2026

A Roth IRA is a retirement account funded with after-tax dollars — you pay taxes on contributions now, but your money grows tax-free and all qualified withdrawals in retirement are completely tax-free. This is the opposite of a Traditional IRA where you deduct contributions now but pay taxes on withdrawals. The Roth advantage is powerful: if you contribute $7,000 per year from age 25 to 65 and earn an average 8 percent annual return, you will accumulate approximately $1.9 million — all of which you can withdraw tax-free in retirement. With a Traditional IRA, that same $1.9 million would be reduced by 20 to 30 percent when you withdraw and pay taxes. Additional Roth IRA benefits include no required minimum distributions (RMDs) during your lifetime, allowing you to let the money compound indefinitely and pass it tax-free to heirs. You can withdraw your contributions (not earnings) at any time without taxes or penalties, making it a flexible emergency backstop.

The 2026 Roth IRA contribution limit is $7,000 per person ($8,000 if age 50 or older). You can contribute to both a Roth IRA and a 401(k) in the same year — they have separate limits. However, Roth IRA contributions have income restrictions. For single filers, you can contribute the full amount if your modified adjusted gross income (MAGI) is below $150,000, a reduced amount between $150,000 and $165,000, and nothing above $165,000. For married filing jointly, full contributions are allowed below $236,000, reduced between $236,000 and $246,000, and phased out above $246,000. If your income exceeds these limits, you cannot contribute directly but can use the backdoor Roth IRA strategy (covered in the next section). Contributions can be made from January 1 of the tax year through the tax filing deadline (typically April 15 of the following year). You must have earned income (wages, self-employment income, or alimony) at least equal to your contribution. Non-working spouses can contribute to a spousal Roth IRA based on the working spouse's earned income. Maximize contributions early in the year rather than waiting until December — extra months of tax-free growth compound significantly over decades.

If your income exceeds Roth IRA limits, the backdoor Roth strategy lets you contribute indirectly. The process is straightforward: contribute $7,000 to a Traditional IRA (non-deductible since you exceed income limits for deductible contributions), then convert the Traditional IRA to a Roth IRA, paying taxes only on any investment gains that occurred between contribution and conversion. If you convert quickly, there may be little to no taxable gain. The critical caveat is the pro-rata rule. If you have any existing pre-tax money in Traditional, SEP, or SIMPLE IRAs, the conversion is taxed proportionally based on your total IRA balance, not just the amount you contributed. For example, if you have $93,000 in a pre-tax rollover IRA and contribute $7,000 non-deductible to a new Traditional IRA, only 7 percent ($7,000 out of $100,000) of any conversion is tax-free. To avoid this, roll existing pre-tax IRA funds into your employer's 401(k) before executing the backdoor conversion. The mega backdoor Roth takes this further — some 401(k) plans allow after-tax contributions above the $23,500 limit (up to the $70,000 combined limit), which can then be converted to Roth. This allows up to $46,500 in additional Roth contributions per year.

A Roth conversion moves money from a Traditional IRA or 401(k) to a Roth IRA. The converted amount is taxed as ordinary income in the year of conversion, but then grows and is withdrawn tax-free forever. The optimal strategy is to convert during low-income years when you are in a lower tax bracket: early retirement before Social Security begins, a gap year between jobs, a year with unusually low income, or years when tax brackets are historically low. Convert just enough each year to fill up your current tax bracket without bumping into the next one. For example, if you are in the 22 percent bracket with $15,000 of room before reaching the 24 percent bracket, convert exactly $15,000 to pay 22 percent now instead of potentially higher rates later. This bracket-filling strategy executed over 5 to 10 years can convert hundreds of thousands of dollars at favorable rates.

Roth conversions also reduce future RMDs, which can lower your Medicare premiums (based on income) and reduce the portion of Social Security benefits that is taxable.

Because Roth IRA withdrawals are tax-free, you should hold your highest-growth (and therefore highest-taxed) investments here. This concept is called asset location — placing investments in the account type that provides the greatest tax benefit. Hold high-growth stocks, REITs (which generate ordinary income dividends), and actively traded funds in your Roth IRA where all growth is tax-free. Hold bonds and other income-generating investments in Traditional accounts where they generate tax-deferred income. For most people, a diversified portfolio of low-cost index funds works best. A simple allocation for a Roth IRA could be: 80 percent in a total US stock market index fund, 15 percent in an international stock index fund, and 5 percent in a small-cap value fund for higher expected returns. As you approach retirement, gradually shift toward more bonds and stable assets. Avoid frequent trading in your Roth IRA — while there are no tax consequences for trading within the account, frequent trading typically underperforms a buy-and-hold strategy due to market timing failures.

Roth IRA withdrawals follow specific ordering rules. First, your direct contributions come out tax-free and penalty-free at any time, regardless of age. This makes Roth IRAs a flexible emergency fund backstop. Second, converted amounts come out tax-free but are subject to a 5-year holding period — each conversion starts its own 5-year clock. If you withdraw converted funds within 5 years and are under age 59 and a half, you owe a 10 percent early withdrawal penalty (but no income tax since you already paid tax on the conversion). Third, earnings come out tax-free and penalty-free only if you are at least 59 and a half AND the account has been open for at least 5 years from your first contribution. Before meeting both conditions, earnings may be subject to tax and penalty. The 5-year rule for contributions starts from January 1 of the tax year you made your first Roth IRA contribution. If you made your first contribution for tax year 2026, the 5-year clock starts January 1, 2026, and ends January 1, 2031. Since contributions always come out first and are always tax-free, the 5-year rule only matters for conversions and earnings. Roth IRAs have no required minimum distributions during the owner's lifetime, but inherited Roth IRAs are subject to the 10-year distribution rule for most non-spouse beneficiaries.
