The Tax Math
Real numbers at four income levels. Assumes $7,000 annual contribution, 8% average returns, 30-year time horizon. The question is always: will your tax rate be higher or lower when you withdraw?

The Key Insight
Both accounts grow to the same balance ($838K on $7,000/yr at 8% for 30 years). The only difference is when you pay taxes. With Traditional, you save $840-$1,680/yr in taxes now but owe taxes on every dollar you withdraw. With Roth, you pay that tax now but never pay another cent on $838,000+ in growth. If tax rates rise even 1-2% — which they have in almost every decade of US history — Roth wins at every income level.
Decision Flowchart
Answer one question. Get your answer.
Is your tax rate now LOWER than you expect in retirement?
Roth IRA
Pay taxes at today's lower rate. Withdraw tax-free when your rate is higher.
Is your tax rate now HIGHER than you expect in retirement?
Traditional IRA
Deduct now at the higher rate. Pay taxes later at a lower rate.
Are your current and future tax rates roughly the same?
Roth IRA
When it's a toss-up, Roth wins on flexibility: no RMDs, tax-free withdrawals, better estate planning.
Are you unsure what your future tax rate will be?
Split or default to Roth
Tax diversification hedges your bet. If you can only pick one, Roth is the safer default because tax rates have historically trended upward.

Backdoor Roth IRA: For High Earners
Earn too much for a Roth IRA? Above $165K single or $246K married in 2026? The Backdoor Roth is a legal IRS-approved workaround used by millions of high-income professionals. It is not a loophole — it is a well-established strategy that Congress has explicitly chosen not to close.
Contribute to a Traditional IRA (non-deductible)
You will not get a tax deduction since you are above the income limit, but that is fine — this is a pass-through step.
Convert to Roth IRA immediately
Call your brokerage (Fidelity, Schwab, Vanguard) and convert the balance. Since you already paid taxes on the contribution, the conversion is essentially tax-free.
Invest and enjoy tax-free growth forever
Once in the Roth, all future growth and withdrawals are tax-free. Repeat every year.
Watch Out: The Pro-Rata Rule
If you have any existing pre-tax Traditional IRA balances (including SEP or SIMPLE IRAs), the IRS treats ALL your IRA money as one pool. Your conversion will be partially taxable proportional to your pre-tax balance. Solution: roll any pre-tax IRA money into your 401(k) before executing the Backdoor Roth. This clears the deck so your conversion is 100% tax-free.
Glen's Take
I ran a hedge fund. I have spent over a decade analyzing investments, tax structures, and the compounding math that builds real wealth. Here is what I tell every young person who asks me this question:
If you are in your 20s or 30s, go Roth. Do not overthink it.
Here is why: you are almost certainly in the lowest tax bracket you will ever be in. Paying 12% or 22% tax on $7,000 today to avoid paying 24%, 32%, or more on $838,000+ in growth is the single best tax trade available to an individual investor. It is not even close.
But here is the thing most people miss: tax diversification matters more than picking the “right” account. Having both Roth and Traditional balances in retirement gives you the ability to control your taxable income year by year. Need $80K this year? Pull $50K from Traditional (taxable) and $30K from Roth (tax-free) to stay in a lower bracket. That kind of flexibility is worth more than any calculator can show you.
My personal approach: I max my Roth IRA every single year, no exceptions. My 401(k) contributions go Traditional for the tax deduction at my income level. This gives me both buckets — a tax-free pool and a tax-deferred pool — so future me has options regardless of what Congress does to tax rates.
The worst decision is not making the wrong Roth vs Traditional choice — it is not investing at all. An investor who picked the “wrong” IRA type and contributed $7,000/yr for 30 years has $838,000. Someone who waited to figure out the “perfect” answer and contributed $0 has $0. Start now. Optimize later.
Age-Based Recommendations
General guidelines — your specific tax situation always trumps age-based rules of thumb.
You are likely in the lowest tax bracket you will ever be in. Decades of tax-free compounding ahead of you. Paying 12-22% tax now to never pay taxes on potentially millions in growth is the best trade you will ever make.
Your income is rising but you still have 25-30+ years of tax-free growth ahead. If you are in the 22% bracket, Roth still wins. If you have crossed into the 24% bracket, consider splitting — get some tax relief now while still building your tax-free bucket.
You are likely in or near your peak earning years. The tax deduction from Traditional contributions is most valuable now. But you still need tax diversification for retirement — having both Roth and Traditional balances gives you flexibility to manage your tax bill in retirement.
If you are in your peak earning years and retirement is 10-15 years away, the immediate tax deduction is powerful. You also get $8,000 in contribution limits with the $1,000 catch-up. However, if you expect similar spending in retirement, keep funding some Roth for tax flexibility.
If you are still working and in a high bracket, Traditional reduces your tax bill right now. If you have already retired or are in a lower bracket, Roth conversions can be a powerful strategy — convert Traditional balances to Roth before RMDs kick in at 73, filling up lower tax brackets each year.
Frequently Asked Questions
Should I choose Roth or Traditional IRA?
If your tax rate now is lower than what you expect in retirement, choose Roth — you pay a small tax bill today to avoid a larger one later. If your tax rate now is higher than you expect in retirement, choose Traditional — you get the deduction when it saves you the most. If you are unsure (most people), default to Roth. Tax rates have historically trended upward, and Roth gives you more flexibility with no RMDs, tax-free withdrawals, and better estate planning.
What are the Roth IRA income limits for 2026?
For 2026, you can contribute the full $7,000 to a Roth IRA if your modified adjusted gross income (MAGI) is below $150,000 (single) or $236,000 (married filing jointly). Contributions phase out between $150,000-$165,000 for single filers and $236,000-$246,000 for married filing jointly. Above those limits, you cannot contribute directly — but you can use the Backdoor Roth IRA strategy.
Can I contribute to both a Roth and Traditional IRA?
Yes, but the $7,000 annual limit ($8,000 if 50+) is shared between both accounts. You can split your contributions however you want — $3,500 Roth and $3,500 Traditional, or any combination — as long as the total does not exceed $7,000. Many financial advisors recommend this split approach for tax diversification.
What is a Backdoor Roth IRA?
A Backdoor Roth IRA is a legal strategy for high earners who exceed Roth IRA income limits. You contribute to a Traditional IRA (non-deductible since you are above the income limit), then immediately convert it to a Roth IRA. Since you already paid taxes on the contribution, the conversion is essentially tax-free — as long as you have no other pre-tax IRA balances. Watch out for the pro-rata rule: if you have existing Traditional IRA balances, a portion of your conversion will be taxable.
What happens if I withdraw from my Roth IRA early?
Roth IRA contributions (not earnings) can be withdrawn at any time, tax-free and penalty-free, regardless of your age. This is a major advantage over Traditional IRAs. Earnings, however, are subject to a 10% penalty and income tax if withdrawn before age 59.5 and before the account has been open for 5 years. Exceptions include first-time home purchase (up to $10,000), disability, and certain medical expenses.
Do Roth IRAs have Required Minimum Distributions (RMDs)?
No. Roth IRAs have no RMDs during the original owner's lifetime. Your money can grow tax-free for as long as you live, and you never have to withdraw a penny if you do not want to. This is one of the biggest advantages of Roth over Traditional. Traditional IRAs require minimum distributions starting at age 73, which forces you to take taxable withdrawals whether you need the money or not.
Is a Roth conversion worth it?
A Roth conversion — moving money from a Traditional IRA to a Roth IRA — can be extremely valuable if done at the right time. The best opportunities are years when your income is unusually low (job transition, sabbatical, early retirement before Social Security kicks in). You pay taxes on the converted amount at your current rate, then it grows tax-free forever. The ideal strategy is to convert just enough each year to 'fill up' your current tax bracket without pushing into the next one.
Which is better for estate planning: Roth or Traditional IRA?
Roth IRA wins decisively for estate planning. When your heirs inherit a Roth IRA, they pay zero federal income tax on withdrawals. With a Traditional IRA, your heirs must pay income tax on every dollar they withdraw — potentially at high rates if they are in their peak earning years. Under the SECURE Act, non-spouse beneficiaries must empty the account within 10 years. With a Roth, that 10-year withdrawal is tax-free. With a Traditional IRA, it could push them into a higher bracket for a decade.
Can I have a Roth IRA and a 401(k)?
Absolutely. A Roth IRA and a 401(k) have separate contribution limits. In 2026, you can contribute $7,000 to your Roth IRA and $23,500 to your 401(k) — that is $30,500 in tax-advantaged retirement savings ($39,000 if you are 50+). The optimal strategy is: (1) 401(k) up to the employer match, (2) max out Roth IRA, (3) max out remaining 401(k) space.
What investments should I hold in my Roth IRA?
Your highest-growth investments belong in your Roth IRA because the growth is tax-free. Put your stock index funds, growth stocks, and small-cap funds in the Roth. Put bonds, REITs, and dividend-heavy stocks in your Traditional IRA or 401(k) since those generate taxable income anyway. This is called 'asset location' — not to be confused with asset allocation — and it can save you thousands in taxes over a lifetime.
The Bottom Line
Roth and Traditional IRAs are both excellent retirement vehicles. The difference is when you pay taxes, not whether you pay them. If you are young and in a low bracket, Roth is almost always the right call. If you are in your peak earning years, Traditional gives you the biggest immediate tax break. If you want maximum flexibility in retirement, contribute to both.
A 25-year-old who contributes $7,000/yr to either IRA at 8% returns will have $838,000 by age 55. With a Roth, that entire amount is tax-free. With a Traditional, you might owe $170,000-$250,000+ in taxes on withdrawals depending on your bracket. That tax bill is the price you pay for the deduction you took decades ago.
The only truly wrong answer is not investing at all. Pick one. Start today. Your 65-year-old self will not care which IRA type you chose — they will care that you chose at all.
