Tax-Free Trading: How Roth Accounts Change the Math in 2026

NEW YORK – August 18, 2026 – Most of the retirement accounts we look at at Q3 aren’t built the way their owners think they are. So we tend to look at active trading a little differently than a brokerage does. When a trader has a great year, the return is only half the story. The other half is how much of it the IRS takes, again, every April.

And here’s the part that’s easy to forget, In a regular taxable brokerage account, you settle up with the government every year. If you sell a stock you’ve held one year or less at a profit and that gain is taxed at your ordinary income rate, which currently tops out at 37%. Higher earners can owe an additional 3.8% net investment income tax on top of that. Trade often and you’re creating a taxable event nearly every time you close a winner. Even losses don’t always land when you need them, because the wash-sale rule can disallow a loss when you buy back the same or a substantially identical security within 30 days.

A Roth account doesn’t work that way. Inside a Roth, buying and selling doesn’t throw off a yearly tax bill, and once you meet the requirements for a qualified distribution, withdrawals in retirement come out tax-free. Same trade, same gain, different tax outcome, largely because of the account it happened in.

A simple side-by-side is usually what makes it click:

Tax Treatment

Taxable brokerage

Roth

 

Short-term gains

Taxed every year, ordinary rates

Not taxed in the account

 

Option premium

Generally a taxable event (treatment varies by contract)

Not taxed in the account

 

 

Dividends

Taxed every year

Not taxed in the account

 

Frequent trading, rebalancing

Each sale can be taxable

No tax on trades inside

 

 

Money out in retirement

Depends on the account and holding period

Qualified withdrawals tax-free

The traders this tends to hit hardest are the income folks. If you’re writing covered calls, selling cash-secured puts, or living off dividends, you’re generating taxable cash flow on a schedule, and in a taxable account you hand over a slice of it every year. Run those same positions inside a Roth and that annual drag goes away. To be clear about what we’re saying and what we’re not: this isn’t a nudge to trade more. It’s a point about where the same activity gets taxed, and where it doesn’t.

So how does money get into a Roth?

Most people’s big tax-advantaged balances aren’t Roth money at all. They’re in traditional IRAs and old 401(k)s. That’s tax-deferred, not tax-free, and the difference costs people more than they realize: you got the deduction going in, but every dollar generally comes out as ordinary income later.

A Roth conversion is how you move money from that traditional bucket into a Roth. You pay ordinary income tax on whatever you convert in the year you do it, and from then on the growth and your qualified withdrawals are tax-free.

If the goal is to trade or hold income positions in a tax-free account, converting is the on-ramp. The real work is figuring out how much to convert, and in which years. That part is rarely obvious.

What actually changed in 2026

For years the whole pitch on conversions leaned on a deadline. Convert before the 2017 tax cuts expired at the end of 2025, the story went, because rates were about to jump. That deadline is gone.

The One Big Beautiful Bill Act, signed July 4, 2025, made the individual tax brackets permanent. For 2026 we’re still looking at the same seven rates, 10% through 37%, adjusted for inflation. If Congress had let the earlier law lapse, most of those rates were scheduled to rise and the top rate would have returned to 39.6%.

This is where our view runs against the grain, because we think a lot of people are reading it wrong. The permanence didn’t remove the reason to convert. It removed the artificial urgency. Plenty of investors hear “rates aren’t going up” and translate it to “nothing to do here,” and that can be a mistake.

The case for converting was never really about beating a calendar. It’s about your own numbers: how big your traditional balance is, what your income looks like now versus later, and what your required withdrawals may do to your bracket once they start.

The one part traders grasp instantly

You pay conversion tax on the dollar value you move. So when a holding is down, the same number of shares converts at a smaller tax cost, and if they recover, that recovery happens inside the Roth, tax-free. Traders tend to get this one right away, because it’s just cost basis and timing.

The caveat we give everyone still holds. This is one input, not a signal. The market can keep falling after you convert, and you still owe the tax on what you converted. It’s a factor to weigh alongside your bracket and how much cash you have on hand to cover the bill, not a reason to convert on its own.

Before you do it, the downsides

A conversion isn’t free, and one piece of it can’t be undone. The things we make sure people understand first:

The tax is due now

Whatever you convert gets added to this year’s taxable income, and a large conversion can push part of your income into a higher bracket.

You can’t reverse it

The ability to recharacterize a conversion was eliminated for conversions made in 2018 and later. Once it’s done, it’s done.

It can raise other costs

A bigger income number can trigger higher Medicare premiums (IRMAA), which are based on your income from two years earlier, and for people under 65 buying coverage through the Marketplace it can reduce a premium tax credit.

Each conversion has its own five-year clock

To withdraw converted amounts before age 59 1/2 without a 10% penalty, those funds generally must stay in the Roth for five years, tracked separately for each conversion.

Where the tax gets paid matters

The math generally works best when you cover the conversion tax with money from outside the retirement account, so the full balance keeps compounding. Pay it from the IRA itself and you have weakened the result.

And watch your state

State income tax treatment, where you live now and where you expect to live later, can change the answer.

Can you even trade options in a Roth?

Yes, within limits, and it’s one of the questions we field most. Many brokers will let you run defined-risk strategies in a Roth IRA depending on your approval level: covered calls, cash-secured puts, and long options are commonly permitted.

What you generally can’t do is trade on margin or use strategies that require it, such as selling naked calls, because IRAs can’t be margin accounts in the usual sense. Every broker sets its own rules and approval levels, so check what yours allows before you build a plan around it.

Who should actually be looking at this

In our experience it tends to matter most for self-directed investors with sizable traditional balances, who expect their taxable income to be as high or higher down the road, and who have cash outside the account to pay the conversion tax. If that’s not you, a conversion may do more harm than good.

And the complexity is real, which is a big part of what our team does. Required withdrawals, Medicare surcharges, the narrower brackets a surviving spouse can face, heirs who under current rules generally must empty an inherited IRA within ten years: all of it interacts, and it plays out over decades, not a single tax year. This is where multi-year modeling matters.

A fiduciary firm that specializes in Roth conversion strategy can run the projection across your whole retirement, not just this year’s return. The aim isn’t to convert as much as possible. It’s to convert the right amount, in the right years, for your situation.

Frequently Asked Questions

Are gains from trading inside a Roth IRA taxed?

Not while they stay in the account, and qualified withdrawals in retirement are tax-free. Compare that to a taxable brokerage account, where short-term gains, most option premium, and dividends are taxed every year. The trade-off is that Roth contributions and conversions are funded with money that has already been taxed.

Can you trade options in a Roth IRA?

Often, within limits. Many brokers permit defined-risk strategies such as covered calls, cash-secured puts, and long options in a Roth IRA, depending on your approval level. Strategies that require margin, such as selling naked calls, generally aren’t allowed, since IRAs can’t trade on margin the way a taxable account can. Confirm the specifics with your broker.

Is a Roth conversion still worth it in 2026?

It can be. Permanent tax rates took away the deadline pressure, but the long-term reasons to convert (reducing future required withdrawals, managing Medicare surcharges, and moving assets into a tax-free account) still apply. The right answer depends on your income trajectory, account size, and state.

Do you pay tax when you convert to a Roth?

Yes. The amount you convert is added to that year’s taxable income and taxed at ordinary income rates. It’s why many investors spread conversions over several years and pay the tax from funds held outside the retirement account.

Should I convert during a market downturn?

A downturn can lower the tax cost of converting a given number of shares, and any recovery inside the Roth is tax-free. Even so, it’s one factor, not a market-timing signal, and the tax is owed whether or not the market comes back.
