For tax year 2026, direct Roth IRA contributions phase out at $153,000–$168,000 MAGI (single or head of household) and $242,000–$252,000 (married filing jointly). The IRA contribution limit is $7,500, or $8,600 if you are 50 or older. The backdoor Roth strategy — a non-deductible Traditional IRA contribution followed by a Roth conversion — lets high earners contribute above these limits, but it is not automatically tax-free: the pro-rata rule taxes part of the conversion in proportion to any pre-tax Traditional, SEP or SIMPLE IRA balance, and the conversion must be reported on Form 8606.
- Who this is for
- High-income immigrants and NRIs in the US who earn above the Roth IRA direct-contribution income limits
- Timeline / decision window
- You can make a prior-year IRA contribution up to the April tax-filing deadline, but conversions are reported in the calendar year they happen. Report the whole flow on Form 8606 for that tax year.
What you'll need for the calculator
- Your tax filing status (single, married filing jointly, etc.)
- Modified adjusted gross income (MAGI) for the tax year
- Any existing pre-tax Traditional / SEP / SIMPLE IRA balances (for the pro-rata rule)
- How much you intend to contribute this year
- Whether you may leave the US / return to India later
Numbers shown are estimates. Tax rates, fees, thresholds, and treaty rules change and depend on your visa status, state, and individual circumstances — verify with a qualified professional before acting.

A backdoor Roth may be an option — see the pro-rata check below
- Check your combined Traditional/SEP/SIMPLE IRA balance — it drives the pro-rata calculation
- If your employer's plan accepts incoming rollovers, rolling pre-tax IRA money into it can reduce the pro-rata impact — plans are not required to accept them, so confirm with your plan administrator first
- Make a nondeductible contribution to a Traditional IRA
- Convert to Roth, and expect any earnings in the interim to be taxable
- File Form 8606 to report the nondeductible basis and the conversion
- Avoid new pre-tax IRA contributions later in the same year

What your result means
The tool tells you whether your income blocks a direct Roth contribution (so a backdoor is worth considering) and flags whether existing pre-tax IRA balances would make the pro-rata rule create tax on a conversion. A 'clean' result means the strategy can likely be done with little tax; a pro-rata warning means you would want to reduce pre-tax IRA balances before year end, or accept a partial tax hit. Moving pre-tax IRA money into an employer 401(k) is one way to do that, but employer plans are not required to accept incoming rollovers — confirm with your plan administrator before relying on it.
How the backdoor Roth works
Direct Roth contribution limits
If your income is below the phase-out range for your filing status, just contribute to a Roth directly — you don't need the backdoor at all. The backdoor only matters when your income is too high for a direct Roth contribution.
Non-deductible Traditional IRA contribution
There's no income limit to contribute to a Traditional IRA on a non-deductible (after-tax) basis. This is step one of the backdoor: put after-tax money into a Traditional IRA.
Roth conversion
Step two is converting that Traditional IRA to a Roth. A backdoor Roth is not automatically tax-free: the contribution was after-tax, so converting before it earns much limits the taxable amount, but any earnings in the interim are taxable and the pro-rata rule can make a large share of the conversion taxable regardless of timing.
The pro-rata rule
The catch: the IRS treats all your Traditional/SEP/SIMPLE IRAs as one pool, measured by their combined balance on December 31 of the conversion year — not on the day you convert. If you hold pre-tax IRA money at that point, part of every conversion is taxable in proportion to the pre-tax share, so a clean backdoor Roth usually requires little or no pre-tax IRA balance at year end.
Form 8606
You file Form 8606 to report the non-deductible contribution and the conversion, establishing your basis so the after-tax portion isn't taxed again.
Tax consequences
Tax on the conversion
If you have no pre-tax IRA balances at year end and convert soon after contributing, the taxable amount is usually small — you already paid tax on the contributed dollars. Any earnings between contribution and conversion are still taxable income, so the conversion is rarely exactly zero-tax.
Pro-rata tax
If you hold pre-tax IRA money, the taxable portion of the conversion equals the pre-tax share of your total IRA balances. This can turn a 'free' backdoor Roth into a taxable event.
Form 8606 basis tracking
Filing Form 8606 each year records your after-tax basis. Skipping it risks being taxed twice on the same dollars later.
If you later return to India
A Roth IRA's qualified withdrawals are tax-free in the US, but India does not recognize the Roth wrapper — once you're an ordinary resident (ROR), India may tax the growth. RNOR timing and the DTAA matter if you plan to return.
Step-by-step process
- 1Check your MAGI against the Roth phase-out for your filing status to confirm you actually need the backdoor.
- 2Reduce or eliminate pre-tax Traditional/SEP/SIMPLE IRA balances before December 31 to limit the pro-rata rule. Rolling them into an employer 401(k) is a common route, but check first — plans are not obliged to accept incoming rollovers.
- 3Contribute after-tax money to a Traditional IRA (non-deductible).
- 4Convert the Traditional IRA to a Roth IRA — ideally soon after, before it earns much.
- 5File Form 8606 for the year to report the non-deductible contribution and the conversion.
- 6If you may return to India, factor in how RNOR/ROR status and the DTAA will treat the Roth later.
Common mistakes to avoid
- Converting while holding pre-tax IRA money and getting an unexpected pro-rata tax bill.
- Forgetting to file Form 8606, losing the record of after-tax basis.
- Letting the Traditional IRA sit and earn a lot before converting, so the earnings become taxable at conversion.
- Assuming a Roth stays tax-free after moving to India — India may tax the growth once you're ROR.
- Doing a backdoor Roth when your income is actually below the limit and a direct contribution was allowed.
Example scenario
High-income H-1B couple, married filing jointly
Arjun and Meera are on H-1B, file jointly, and have a 2026 MAGI of $260,000 — above the $242,000–$252,000 direct-Roth phase-out — so they can't contribute to a Roth directly. Neither holds any pre-tax IRA balance. Each contributes the $7,500 annual limit to a Traditional IRA (non-deductible) and converts to a Roth a few days later; only the small amount of earnings in those few days is taxable. They each file Form 8606. Because they may return to India in a few years, they note that qualified Roth withdrawals are US-tax-free but India could tax the growth once they become ROR, so they plan around their RNOR window.

Frequently asked questions
What are the 2026 Roth IRA income limits and contribution limits?
For tax year 2026 the IRA contribution limit is $7,500, rising to $8,600 if you are 50 or older (a $1,100 catch-up). Direct Roth contributions phase out between $153,000 and $168,000 of MAGI for single filers and heads of household, and between $242,000 and $252,000 for married couples filing jointly. A married person filing separately who lived with their spouse at any time during the year phases out between $0 and $10,000; one who lived apart for the entire year is treated as single for this purpose.
Is a backdoor Roth tax-free?
Not automatically. The contribution itself is after-tax, so it is not taxed again on conversion, but two things can create tax: any earnings between the contribution and the conversion are taxable, and the pro-rata rule taxes part of the conversion in proportion to your combined pre-tax Traditional, SEP and SIMPLE IRA balance on December 31 of the conversion year. Someone with a large pre-tax IRA balance can find most of a backdoor conversion taxable.
Can H-1B workers do a backdoor Roth IRA?
Yes. Anyone with US earned income and US tax residency — including H-1B, L-1, and F-1 holders who are resident for tax purposes — can generally use the backdoor Roth strategy. The rules are the same as for US citizens; visa status by itself doesn't disqualify you.
Is a backdoor Roth legal?
Yes. It's a widely used, IRS-acknowledged strategy that combines a non-deductible Traditional IRA contribution with a Roth conversion. You must report it correctly on Form 8606 and watch the pro-rata rule, but the approach itself is legitimate.
What is the pro-rata rule?
The IRS treats all your Traditional, SEP, and SIMPLE IRAs as one combined pool. When you convert, the taxable portion equals the pre-tax share of that total pool — so if you hold pre-tax IRA money, part of a 'backdoor' conversion becomes taxable rather than tax-free.
Do I need Form 8606?
Yes. Form 8606 reports your non-deductible Traditional IRA contribution and the Roth conversion, and records your after-tax basis. Filing it is what keeps the IRS from taxing the same after-tax dollars a second time.
Should I do a backdoor Roth if I may return to India?
It can still make sense, but with a caveat: India doesn't recognize the Roth wrapper. US-qualified Roth withdrawals are US-tax-free, but once you're an ordinary resident (ROR) in India, India may tax the growth. Plan around your RNOR window and use the DTAA where it applies.
Is a Roth IRA taxable in India?
India doesn't give the Roth the same tax-free treatment the US does. While you're NRI or RNOR, foreign income is often outside India's net, but once you become ROR, India may tax Roth earnings as worldwide income. The DTAA helps avoid double taxation on the US-taxed portion.
