Roth IRA Guide 2026: Contribution Limits, Income Limits & Tax-Free Growth

What Is a Roth IRA?

A Roth IRA is a retirement account where you contribute after-tax dollars, your money grows tax-free, and qualified withdrawals in retirement are completely tax-free. It's one of the most powerful retirement savings vehicles available to American investors.

Unlike a traditional IRA or 401(k), you don't get a tax deduction when you contribute. But here's the trade-off that makes it worth it:

Tax-free growth: Every dollar of investment gains is never taxed
Tax-free withdrawals: Take money out in retirement without owing a penny to the IRS
No required minimum distributions: Keep your money growing as long as you want
Flexibility: Withdraw contributions (not earnings) anytime without penalty

Think about what tax-free growth means. If you invest $7,000 at age 25 and it grows to $100,000 by retirement, that entire $100,000 is yours. With a traditional account, you'd owe taxes on the $93,000 in gains.

How a Roth IRA Works

Step	What Happens	Tax Impact
1. Contribution	You deposit after-tax money	No deduction (already taxed)
2. Investment	Choose stocks, bonds, ETFs, mutual funds	No tax on trades
3. Growth	Investments compound over decades	No tax on dividends or gains
4. Withdrawal	Take money after age 59½	Completely tax-free

Who Can Open a Roth IRA?

You need earned income to contribute to a Roth IRA. This includes wages, salaries, tips, bonuses, and self-employment income. Investment income, rental income, and Social Security don't count.

There's also an income limit—if you earn too much, you can't contribute directly. But there's a workaround called the backdoor Roth (more on that later).

2026 Contribution Limits

The IRS sets annual limits on Roth IRA contributions. Here are the 2026 numbers:

Current Limits

Category	2026 Limit	Notes
Under age 50	$7,000	Combined limit for all IRAs
Age 50 and older	$8,000	Includes $1,000 catch-up
Spousal IRA	$7,000	For non-working spouse

Important: The $7,000 limit is combined across ALL your IRAs—traditional and Roth. You can't put $7,000 in a Roth AND $7,000 in a traditional. The total can't exceed $7,000 (or $8,000 if 50+).

Contribution Deadline

You have until the tax filing deadline (typically April 15) to make contributions for the previous year. This means you can make 2025 contributions until April 15, 2026. Many people don't realize this and miss out on extra contribution time.

Example: Maximizing Your Contributions

Scenario	Annual Contribution	After 30 Years (7% return)
Max contribution every year	$7,000	$708,000
Half the max	$3,500	$354,000
$100/month	$1,200	$122,000

Every dollar counts. Even if you can't max out, contribute what you can. You can always increase later.

Income Limits and Phase-Outs

Here's where Roth IRAs get tricky. The IRS imposes income limits that reduce or eliminate your ability to contribute directly.

2026 Income Limits

Filing Status	Full Contribution	Reduced Contribution	No Contribution
Single/Head of Household	Under $150,000	$150,000 - $165,000	Over $165,000
Married Filing Jointly	Under $236,000	$236,000 - $246,000	Over $246,000
Married Filing Separately	N/A	$0 - $10,000	Over $10,000

These limits use Modified Adjusted Gross Income (MAGI), which is your adjusted gross income with certain deductions added back. For most people, MAGI is close to their regular AGI.

Calculating Your Reduced Contribution

If you're in the phase-out range, here's how to calculate your reduced limit:

Subtract the lower limit from your MAGI
Divide by $15,000 (single) or $10,000 (married)
Multiply by $7,000
Subtract from $7,000

Example: Single filer with $157,500 MAGI

$157,500 - $150,000 = $7,500
$7,500 ÷ $15,000 = 0.50
0.50 × $7,000 = $3,500
$7,000 - $3,500 = $3,500 reduced limit

If your income exceeds the limits, don't worry. The backdoor Roth IRA lets you contribute regardless of income. It's completely legal and widely used.

The 5-Year Rule Explained

The Roth IRA has a 5-year rule that confuses many investors. Actually, there are TWO 5-year rules you need to know:

Rule 1: The 5-Year Rule for Earnings

For your EARNINGS (not contributions) to be withdrawn tax-free and penalty-free, you must meet BOTH conditions:

You're age 59½ or older
It's been at least 5 years since your first Roth IRA contribution

The 5-year clock starts on January 1 of the year you make your first contribution. If you contribute in December 2026, the clock starts January 1, 2026, and you satisfy the rule on January 1, 2031.

Rule 2: The 5-Year Rule for Conversions

If you convert money from a traditional IRA to a Roth IRA, each conversion has its own 5-year waiting period before you can withdraw that converted amount penalty-free.

Conversion Year	Penalty-Free After	5-Year Date
2026	January 1, 2031	Anytime in 2031
2027	January 1, 2032	Anytime in 2032
2028	January 1, 2033	Anytime in 2033

This matters primarily for early retirees who plan to access Roth funds before age 59½.

What You Can Always Withdraw

Here's the good news: you can ALWAYS withdraw your original contributions tax-free and penalty-free, regardless of age or the 5-year rule. The IRS uses ordering rules—contributions come out first, then conversions, then earnings.

Backdoor Roth Strategy

If your income exceeds the Roth IRA limits, the backdoor Roth IRA is your solution. It's a legal workaround that high earners have used for years.

How It Works

Contribute to a traditional IRA (no income limits for non-deductible contributions)
Convert the traditional IRA to a Roth IRA
Pay taxes on any gains between contribution and conversion
Enjoy tax-free growth going forward

Step-by-Step Process

Step	Action	Timeline
1	Open a traditional IRA (if needed)	Day 1
2	Contribute $7,000 after-tax	Day 1
3	Wait for contribution to settle	1-3 days
4	Convert entire balance to Roth IRA	Day 3-5
5	File Form 8606 with your taxes	Tax season

The Pro-Rata Rule Warning

Here's the critical catch: if you have ANY pre-tax money in traditional IRAs, the IRS applies the pro-rata rule. You can't just convert your non-deductible contributions—the IRS treats your conversion as a proportional mix of pre-tax and after-tax money.

Example:

You have $93,000 pre-tax in a rollover IRA
You contribute $7,000 non-deductible to a traditional IRA
Total IRA balance: $100,000 ($93,000 pre-tax, $7,000 after-tax)
You convert $7,000
93% of conversion ($6,510) is taxable because 93% of your IRA is pre-tax

Solutions to the pro-rata problem:

Roll pre-tax IRA money into your 401(k) before converting
Convert everything to Roth (pay taxes now)
Wait until you have no pre-tax IRA balances

Investment Options

A Roth IRA is just an account type—a tax wrapper. Inside it, you can invest in almost anything:

Common Investment Choices

Investment Type	Pros	Best For
Total stock market index funds	Broad diversification, low fees	Core long-term holding
S&P 500 index funds	Large-cap US exposure	Growth-focused investors
International stock funds	Global diversification	Reducing US concentration
Bond funds	Lower volatility, income	Closer to retirement
Target date funds	Automatic rebalancing	Hands-off investors
Individual stocks	Potential for higher returns	Experienced investors
REITs	Real estate exposure, dividends	Income + diversification

Tax-Efficient Placement Strategy

Since Roth IRA growth is tax-free forever, prioritize holding your highest-growth investments here:

Best for Roth IRA: Growth stocks, small-cap funds, emerging markets—assets with highest expected long-term growth
Less ideal: Bonds and dividend-heavy stocks (the tax-free benefit is wasted on lower returns)

If you have $500,000 in stocks that grows to $2 million, that $1.5 million in gains is completely tax-free in a Roth. Put your boring bonds in your taxable account where they generate less taxable income.

Where to Open a Roth IRA

Choose a low-cost brokerage with no account fees and commission-free trading. Popular options include Fidelity, Vanguard, Charles Schwab, and online brokerages. Look for:

No account minimums
Commission-free trades
Low-cost index funds
Good customer service
Easy-to-use interface

Roth vs Traditional IRA

The classic retirement question: pay taxes now (Roth) or later (traditional)?

Side-by-Side Comparison

Feature	Roth IRA	Traditional IRA
Tax on contributions	After-tax (no deduction)	Pre-tax (tax deduction)
Tax on growth	Tax-free	Tax-deferred
Tax on withdrawals	Tax-free	Taxed as ordinary income
Required minimum distributions	None	Start at age 73
Income limits for contributions	Yes ($165K single, $246K married)	No (for contributions)
Income limits for deduction	N/A	Yes (if covered by workplace plan)
Early withdrawal of contributions	Anytime, tax and penalty-free	Taxes and 10% penalty

When to Choose Roth

You're in a low tax bracket now: Pay the lower taxes now, enjoy tax-free retirement
You expect higher income later: Early career, expect significant salary growth
You want flexibility: Access contributions anytime without penalty
You want to avoid RMDs: Keep money growing indefinitely
Estate planning: Leave tax-free money to heirs
You expect tax rates to rise: Lock in today's rates

When to Choose Traditional

You're in a high tax bracket: The deduction is more valuable
You need the tax deduction now: Reduce current tax bill
You expect lower taxes in retirement: Will withdraw less income
You're close to retirement: Less time for tax-free growth to compound

The Math: An Example

Assuming you invest $7,000/year for 30 years at 7% returns:

Scenario	Roth IRA	Traditional IRA
Balance at retirement	$708,000	$708,000
Tax rate in retirement	0%	22%
After-tax value	$708,000	$552,000

If you're in the same tax bracket now and in retirement, the accounts are mathematically equivalent. But if you expect higher taxes later, Roth wins.

Your Action Plan

Ready to start or optimize your Roth IRA? Here's your roadmap:

If You're Starting From Zero

Check your income against the limits—can you contribute directly?
Open a Roth IRA at a low-cost brokerage
Set up automatic monthly contributions ($584/month to max out)
Choose a simple investment (total stock market index or target date fund)
Don't touch it for decades

If You're Over the Income Limit

Check if you have pre-tax IRA balances (pro-rata rule)
If yes, consider rolling them into a 401(k)
Open a traditional IRA with the same brokerage as your Roth
Execute the backdoor Roth strategy
Keep records and file Form 8606

If You Already Have a Roth IRA

Verify you're contributing the maximum ($7,000 or $8,000)
Review your investment allocation
Ensure you're holding high-growth assets in the Roth
Check beneficiary designations are up to date

The Power of Starting Early

Here's what maxing out your Roth IRA looks like over time:

Starting Age	Years to 65	Total Contributed	Account Value at 65 (7%)
25	40	$280,000	$1,497,000
30	35	$245,000	$1,028,000
35	30	$210,000	$708,000
40	25	$175,000	$474,000
45	20	$140,000	$307,000

Starting at 25 instead of 35 more than doubles your ending balance. The best time to start was yesterday. The second best time is today.

Key Deadlines to Remember

Contribution deadline: April 15 of the following year (April 15, 2027 for 2026 contributions)
Excess contribution fix: Must remove by October 15 deadline with extension
Annual review: Check income against limits each year

The Roth IRA is one of the best deals in the tax code. Tax-free growth for life, no required distributions, and flexibility to access contributions. Whether you contribute directly or through the backdoor, get money into a Roth IRA as early and as often as possible.

Your future self—enjoying tax-free income in retirement—will thank you.
