ETFs are one of the most tax-efficient investment vehicles available to U.S. investors. The reason comes down to a specific structural feature: the in-kind creation and redemption process, governed under Section 852 of the Internal Revenue Code, which allows ETF managers to exchange securities without triggering taxable events for shareholders. This mechanism is the single biggest reason ETFs beat mutual funds on taxes.
Only 7% of ETFs paid a capital gain in 2025, compared with 52% of mutual funds. That gap has stayed consistent for nearly a decade.

What Makes ETFs So Tax Efficient in the First Place?
The IRS treats ETFs and mutual funds the same way on paper. Both pay taxes on capital gains and dividends. The difference is when and how often those taxable events happen. ETFs are built to minimize those taxable events through their structure — not through special tax breaks.
A mutual fund manager must sell securities inside the fund to raise cash when investors redeem their shares. If those securities have gone up in value, selling them creates a capital gain. That gain gets passed along to every shareholder in the fund — even investors who just bought in last week and didn’t benefit from the earlier price increase.
ETFs work differently. When large institutional players called authorized participants (APs) want to redeem ETF shares, they don’t get cash. They get the actual underlying securities delivered in-kind. The ETF manager hands over a basket of stocks instead of selling them. Because no sale happens, no capital gain is triggered.
This single feature is the engine behind ETF tax efficiency. The IRS does not treat an in-kind exchange of securities as a taxable event, so the fund avoids distributing gains to shareholders.
How the In-Kind Creation and Redemption Process Works
The process starts with authorized participants — large broker-dealers or financial institutions that work directly with ETF issuers. APs are the only entities that can create or redeem ETF shares. Regular investors like you and me buy and sell ETF shares on the stock exchange, which means our trades happen between investors, not at the fund level.
How Creation Works
An AP gathers a basket of the underlying securities that match the ETF’s holdings — typically in large blocks of at least 25,000 shares called creation units. The AP delivers this basket to the ETF issuer. In exchange, the ETF issuer gives the AP newly created ETF shares, which the AP can then sell on the open market.
No securities were sold. No taxable event occurred. The ETF simply grew by absorbing new securities.
How Redemption Works
When an AP wants to redeem shares, the process runs in reverse. The AP collects enough ETF shares to form a creation unit and delivers them back to the ETF issuer. The issuer then hands the AP a basket of the underlying stocks — again, in-kind. The ETF issuer did not sell any holdings, so no capital gains are realized inside the fund.
This is the critical difference. Mutual fund managers are forced to sell holdings to raise cash for redemptions. ETF managers can hand over the securities themselves, completely avoiding the sale.
Why This Matters for Your Tax Bill
Active ETF managers can even use this mechanism strategically. When a manager wants to remove a stock that has appreciated in value, they can include it in the in-kind redemption basket. This lets the ETF unwind appreciated positions without creating a taxable event for remaining shareholders. It is, in effect, a built-in tax-management tool.
The result is fewer capital gains distributions year after year. According to T. Rowe Price, over a typical investment period, a mutual fund may distribute roughly 50% of returns as year-end capital gains, while an equivalent ETF distributes close to 0%.
ETFs vs. Mutual Funds: The Tax Efficiency Gap by the Numbers
The data makes this one of the clearest comparisons in investing. ETFs distribute fewer capital gains across every asset class, every management style, and every year measured.
| ETF Tax Metric (2025) | Mutual Fund Tax Metric (2025) |
|---|---|
| 7% of all ETFs paid a capital gain | 52% of all mutual funds paid a capital gain |
| 6% of equity ETFs paid a capital gain | 57% of equity mutual funds paid a capital gain |
| 23% of fixed income ETFs paid a capital gain | 37% of fixed income mutual funds paid a capital gain |
| 6% of alternative ETFs paid a capital gain | 30% of alternative mutual funds paid a capital gain |
These figures from State Street Global Advisors cover the full universe of U.S.-listed funds. The long-term average since 2016 shows 9% of ETFs distributing gains versus 53% of mutual funds.
Active ETFs Crush Active Mutual Funds on Taxes
The tax gap gets even wider when you look at actively managed funds. Only 9% of active ETFs issued a capital gain in 2025, compared with 53% of active mutual funds. Active mutual funds also charge an average of 0.32% more in annual fees than their ETF counterparts.
Nearly 27% of active mutual funds both underperformed their benchmark and paid a capital gain in 2025. For active ETFs, that number was just 2%. You could lose money and owe taxes — that is the worst-case scenario for mutual fund investors.
Even passive mutual funds lagged behind. In 2025, 41% of passive mutual funds distributed a capital gain, compared with just 4% of passive ETFs. The ETF structure provides a tax advantage regardless of whether the fund is actively or passively managed.
Real-World Examples: SPY, VTI, and QQQ
Understanding how this plays out with real ETFs makes the concept stick. Three of the most popular ETFs in the world — SPY (SPDR S&P 500 ETF), VTI (Vanguard Total Stock Market ETF), and QQQ (Invesco QQQ Trust) — all showcase different aspects of ETF tax efficiency.
SPY: The Original Tax-Efficient Giant
SPY tracks the S&P 500 and is the largest ETF in the world. Because it is an index fund, it has very low portfolio turnover. Stocks only leave the portfolio when they are removed from the S&P 500 index. Combined with the in-kind redemption process, SPY has historically avoided paying capital gains to shareholders in most years.
If you held SPY in a taxable brokerage account for 10 years, your main tax obligation would be on the dividends it pays (currently around a 1.2% yield) and the capital gain when you eventually sell. You would not receive surprise capital gains distributions mid-year the way you might with an S&P 500 mutual fund.
VTI: Low Turnover, Maximum Efficiency
VTI tracks the entire U.S. stock market — over 3,600 stocks. Its turnover ratio sits at about 4%, meaning it replaces very few holdings each year. Low turnover combined with the in-kind process means VTI rarely distributes capital gains.
Consider Maria, a 35-year-old investor in New Jersey earning $95,000 per year. She holds $50,000 in VTI inside her taxable brokerage account. Over 10 years, she pays taxes only on VTI’s quarterly dividends and her eventual sale. Her friend James holds $50,000 in a total stock market mutual fund in his taxable account. James receives capital gains distributions almost every year, eroding his after-tax returns even though both funds track the same index.
QQQ: Tech-Heavy but Still Tax-Smart
QQQ tracks the Nasdaq-100, which is dominated by large-cap tech stocks. Despite having higher concentration risk than VTI or SPY, QQQ still benefits from the same in-kind redemption structure. Over the last decade, QQQ posted annualized returns of about 17.7%, beating SPY’s 12.75%.
The key tax insight: those massive gains stayed unrealized inside the ETF. Shareholders only owed capital gains tax when they personally chose to sell their QQQ shares — not because the fund manager triggered a taxable event.
Three Scenarios That Show ETF Tax Efficiency in Action
Scenario 1: The Buy-and-Hold Investor
David, age 40, puts $100,000 into VTI in a taxable account. He plans to hold for 20 years. He is in the 22% federal tax bracket.
| What Happens Inside the ETF | Tax Impact on David |
|---|---|
| APs redeem shares in-kind — no securities sold | David owes $0 in capital gains from fund activity |
| VTI pays quarterly dividends (qualified) | David pays 15% tax on qualified dividends each year |
| David sells VTI after 20 years at a large gain | David pays 15% long-term capital gains tax at sale |
| VTI’s 4% annual turnover triggers minimal internal gains | David avoids annual capital gains distributions |
David controls when he pays his capital gains tax. He is not forced into a tax bill by other investors redeeming their shares.
Scenario 2: The High-Income Earner Switching from Mutual Funds
Priya, age 50, earns $400,000 per year and lives in California. She holds $500,000 in an actively managed large-cap mutual fund. Every year, the fund distributes capital gains — and she pays 20% federal long-term capital gains tax plus the 3.8% Net Investment Income Tax (NIIT) plus 13.3% California state income tax.
| What Priya Does | Tax Consequence |
|---|---|
| Keeps the mutual fund — receives $25,000 in annual capital gains distributions | Pays roughly $9,275 per year in combined federal and state tax on those distributions |
| Sells the mutual fund and moves to an equivalent active ETF | Pays a one-time capital gains tax on the sale, then near-zero distributions going forward |
| Holds the active ETF for 10+ years | Saves potentially $80,000+ in cumulative capital gains taxes over the period |
| Uses the active ETF’s in-kind process to defer gains | Keeps more money invested and compounding |
Priya’s switch triggers a one-time tax bill, but the long-term savings from avoiding annual distributions far outweigh that upfront cost. This is exactly why mutual funds saw $692 billion in outflows in 2025.
Scenario 3: The Retiree Drawing Income
Robert, age 68, is retired and lives in Texas (no state income tax). He has $300,000 in a bond ETF and $200,000 in a dividend-focused equity ETF, both in a taxable account.
| Robert’s Income Source | How It Is Taxed |
|---|---|
| Bond ETF interest payments | Taxed as ordinary income at Robert’s federal rate |
| Equity ETF qualified dividends | Taxed at 0% or 15% depending on Robert’s total income |
| Selling ETF shares for cash | Long-term capital gains rate (0%, 15%, or 20%) if held over 1 year |
| Capital gains distributions from bond ETF | 23% of fixed income ETFs distributed gains in 2025 — bond ETFs are less tax-efficient than equity ETFs |
Robert benefits from living in a state with no income tax. His equity ETF dividends may even qualify for the 0% long-term capital gains rate if his taxable income stays below certain thresholds.
The ETF Types That Lose Their Tax Advantage
Not every ETF is a tax-efficiency champion. Several categories come with structural problems that reduce or eliminate the tax benefits.
International and Emerging Market ETFs
Many emerging market ETFs cannot perform in-kind redemptions because the local markets restrict the delivery of securities. When an AP redeems shares, the ETF manager must sell securities for cash instead. That sale creates a capital gain inside the fund, which gets distributed to all shareholders. Emerging market ETFs can behave a lot like mutual funds from a tax perspective.
Leveraged and Inverse ETFs
Leveraged and inverse ETFs use derivatives — swaps, futures, and options — to amplify daily returns. These derivatives cannot be delivered in-kind. They must be bought or sold, triggering taxable events. Gains from these derivatives receive 60/40 tax treatment from the IRS: 60% of gains are taxed at the long-term rate and 40% at the short-term rate, regardless of how long you held the ETF.
The daily repositioning required to maintain leverage also creates high turnover. Combined with volatile cash flows, leveraged ETFs have historically made significant capital gains distributions on both long and short positions.
Commodity ETFs
Commodity ETFs that hold futures contracts (like many gold and oil ETFs) face the same 60/40 derivative tax treatment. Some commodity ETFs are structured as grantor trusts (like GLD, the SPDR Gold Trust), which means the IRS treats your gains as gains on a collectible — taxed at a maximum rate of 28% instead of the standard 20% long-term capital gains rate.
Exchange-Traded Notes (ETNs): The Tax-Efficiency Exception
ETNs are the most tax-efficient structure in the exchange-traded product universe. They are debt securities issued by a bank, not funds that hold assets. Because ETNs hold no securities internally, there are no dividends or capital gains distributed while you hold them. You only pay tax when you sell the ETN. The trade-off is credit risk — if the issuing bank fails, you could lose your investment.
How Federal Tax Law Treats ETF Gains and Dividends
Under the Internal Revenue Code, the IRS applies the same rules to ETFs as it does to mutual funds and individual stocks. The difference in tax outcomes comes from structure, not from special ETF tax treatment.
Capital Gains Tax Rates
When you sell an ETF at a profit, your gain is either short-term or long-term. Short-term gains (held less than one year) are taxed at your ordinary income tax rate — anywhere from 10% to 37%. Long-term gains (held more than one year) are taxed at preferential rates of 0%, 15%, or 20%.
High earners also face the 3.8% Net Investment Income Tax (NIIT) on top of capital gains if their modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). This NIIT applies to ETF capital gains, dividends, and interest income.
Dividend Tax Rules
ETF dividends fall into two categories. Qualified dividends — those from U.S. companies and certain foreign corporations where you have held the ETF for more than 60 days before the dividend date — are taxed at the lower long-term capital gains rates. Non-qualified (ordinary) dividends are taxed at your regular income tax rate.
Bond ETFs mostly pay ordinary income because interest payments do not qualify for the reduced dividend rate. This is why bond ETFs are inherently less tax-efficient than equity ETFs — a fact confirmed by the data showing 23% of fixed income ETFs distributing gains in 2025 versus just 6% of equity ETFs.
State Tax Differences That Can Cost You Thousands
Federal tax rules are uniform across the country, but state taxes add another layer that varies wildly. Your state of residence can significantly change how tax-efficient your ETF holdings really are.
High-Tax States: California, New York, and New Jersey
If you live in California (top rate 13.3%), New York (top rate 10.9% plus NYC’s additional tax), or New Jersey (top rate 10.75%), your ETF dividends and capital gains face a hefty state tax on top of federal taxes. Priya’s scenario above showed how a California investor could pay over 37% in combined federal and state taxes on capital gains distributions.
In these states, the tax efficiency of ETFs becomes even more valuable because every capital gain you can defer or avoid saves you at both the federal and state level.
No-Income-Tax States: Texas, Florida, Nevada, and Others
Seven states charge no state income tax: Texas, Florida, Nevada, Wyoming, South Dakota, Alaska, and Washington. If you live in one of these states, you pay only federal taxes on your ETF gains and dividends. Robert’s scenario showed how a Texas retiree keeps more of every dollar earned inside an ETF.
Municipal Bond ETFs and the State Tax Puzzle
Municipal bond ETFs like VTEB (Vanguard Tax-Exempt Bond ETF) and MUB (iShares National Muni Bond ETF) are federally tax-exempt. State tax treatment, though, depends on where you live. You generally only get state tax exemption for bonds issued within your own state.
If you live in New York and hold VTEB, only the portion of the fund that holds New York municipal bonds is exempt from NY state tax. The rest is subject to state tax. Some high-tax states like California and New York require at least 50% of a fund’s holdings to be in qualifying securities for state tax exemption to apply.
Treasury Bond ETFs and a Hidden State Tax Break
ETFs that hold U.S. Treasury securities carry a lesser-known benefit: Treasury interest is exempt from state and local taxes. This applies to ETFs and money market funds that invest primarily in Treasuries. The catch is that custodians often fail to isolate the Treasury-derived income on 1099 forms, causing investors to pay state tax they do not owe.
Check your fund company’s annual tax supplement to find the percentage of income derived from U.S. Treasuries. Then claim the state exemption on your state tax return. Missing this step can cost hundreds or thousands of dollars per year in states like California, New York, and Connecticut.
Tax-Loss Harvesting With ETFs: A Powerful Strategy
Tax-loss harvesting is the practice of selling an investment at a loss to offset capital gains elsewhere in your portfolio. ETFs are ideal for this strategy because you can sell one ETF and immediately buy a different ETF that gives you similar market exposure — without running afoul of the IRS wash sale rule.
The Wash Sale Rule: IRS Code Section 1091
The wash sale rule says you cannot deduct a loss if you buy a “substantially identical” security within 30 days before or after the sale. That creates a 61-day total window (30 days before, the sale date, and 30 days after). If you violate this rule, your loss is disallowed and added to the cost basis of the new purchase.
The rule applies to stocks, bonds, mutual funds, ETFs, and even acquisitions inside an IRA. If you sell an ETF at a loss in your taxable account and buy the same ETF in your IRA within the wash sale window, the loss is disallowed.
How to Harvest Losses Without Triggering a Wash Sale
The key is replacing your ETF with one that provides similar but not “substantially identical” exposure. The IRS has never defined exactly what makes two ETFs substantially identical, but industry practice offers clear guidelines.
| Swap That Works (Not Substantially Identical) | Swap That Is Risky (Possibly Substantially Identical) |
|---|---|
| Sell VTI (Vanguard Total Stock Market) → Buy ITOT (iShares Core S&P Total U.S. Stock Market) | Sell VTI → Buy VTSAX (Vanguard Total Stock Market mutual fund) — tracks the same index |
| Sell SPY (S&P 500) → Buy VOO (Vanguard S&P 500) — different issuers but same index, some risk | Sell SPY → Buy IVV (iShares S&P 500) — same index, same structure, higher risk of wash sale |
| Sell QQQ (Nasdaq-100) → Buy VGT (Vanguard Information Technology) — different index, different holdings | Sell QQQ → Buy QQQM (Invesco Nasdaq-100, smaller share version) — essentially the same fund |
| Sell a losing individual stock → Buy a sector ETF covering that industry | Sell a losing stock → Buy the same stock back within 30 days |
A common rule of thumb is that two ETFs with less than 70% overlap in their holdings are generally not considered substantially identical. The IRS retains final authority, and there is no bright-line test written into the tax code.
A Tax-Loss Harvesting Example
Elena holds $80,000 in a total stock market ETF that drops 15% during a market downturn, creating a $12,000 unrealized loss. She also has $12,000 in realized capital gains from selling another investment earlier in the year.
Elena sells the total stock market ETF, realizes the $12,000 loss, and immediately buys a different total stock market ETF from another issuer that tracks a different index. The loss offsets her $12,000 in gains, saving her approximately $1,800 to $2,856 in federal taxes (depending on her bracket). She maintains nearly identical market exposure throughout.
Research suggests that a disciplined ETF tax-loss harvesting strategy can generate 1.5% to 3% in annual tax alpha — extra after-tax return simply from smart loss harvesting.
Mistakes to Avoid With ETF Tax Efficiency
Even tax-efficient investments can become costly if you make common errors. Each of these mistakes has a specific negative consequence.
Holding bond ETFs in a taxable account when you have IRA space. Bond ETF interest is taxed as ordinary income at rates up to 37%. If you have room in a tax-deferred IRA or 401(k), bond ETFs belong there — not in your taxable brokerage account. The consequence: you pay your highest tax rate on income that could have been deferred or sheltered.
Ignoring the wash sale rule when tax-loss harvesting. Buying a “substantially identical” ETF within the 61-day window means your loss is completely disallowed. The disallowed loss gets added to your cost basis in the replacement security, but you lose the immediate tax benefit you were trying to capture.
Assuming all ETFs are tax-efficient. Leveraged ETFs, inverse ETFs, commodity ETFs, and some emerging market ETFs do not have the same in-kind redemption benefit. Holding these in a taxable account can generate significant capital gains distributions every year.
Forgetting to claim the state tax exemption on Treasury ETF income. Fund companies publish the percentage of income from U.S. Treasuries, but custodians do not separate it on your 1099. If you skip this step, you overpay state taxes.
Selling ETFs for short-term gains. ETFs are designed for long-term holding. If you sell within one year, you pay short-term capital gains at your ordinary income rate (up to 37%) instead of the preferential long-term rate (0%, 15%, or 20%). The entire tax advantage of deferral is lost.
Not checking your mutual fund’s capital gains distribution schedule before year-end. Many investors buy a mutual fund in November or December, right before the fund distributes its annual capital gains. You receive a taxable distribution on gains you did not participate in. ETFs rarely have this problem, but it is still worth checking the distribution calendar.
Do’s and Don’ts of ETF Tax Efficiency
| Do | Don’t |
|---|---|
| Do hold equity ETFs in taxable accounts — they generate the fewest capital gains distributions | Don’t hold bond ETFs in taxable accounts if you have tax-advantaged space available |
| Do use ETFs for tax-loss harvesting by swapping to a non-identical ETF | Don’t buy back the same or substantially identical ETF within the 61-day wash sale window |
| Do check your fund’s Treasury income percentage and claim state tax exemptions | Don’t assume your 1099 correctly separates Treasury-exempt income |
| Do hold ETFs long-term to qualify for the lower long-term capital gains rate | Don’t trade ETFs frequently in taxable accounts — short-term gains are taxed at ordinary rates |
| Do consider your state’s income tax rate when choosing between muni bond ETFs and taxable bond ETFs | Don’t buy national muni bond ETFs and assume all income is exempt from your state tax |
| Do compare the capital gains distribution history of any fund before buying | Don’t assume every ETF is tax-efficient — check if it uses derivatives, futures, or cash redemptions |
Pros and Cons of ETFs for Tax Efficiency
| Pros | Cons |
|---|---|
| In-kind redemptions avoid triggering capital gains for shareholders | Bond ETF income is still taxed as ordinary income at high rates |
| You control when to realize gains by choosing when to sell | Emerging market ETFs may not be able to use in-kind redemptions |
| Only 7% of ETFs distributed capital gains in 2025 vs. 52% of mutual funds | Leveraged and inverse ETFs lose most of the tax advantage due to derivative use |
| Tax-loss harvesting is easy with hundreds of similar but non-identical ETFs available | The wash sale rule creates a 61-day window you must carefully navigate |
| Active ETFs are now available with the same tax benefits as index ETFs | Commodity ETFs may be taxed at the 28% collectibles rate |
| State tax exemptions on Treasury ETF income add extra savings | Some custodians do not properly report Treasury income on 1099 forms |
| ETNs offer even greater tax deferral with zero distributions | ETNs carry credit risk — if the issuing bank fails, you lose your investment |
Key Organizations and Entities You Should Know
The IRS sets the federal tax rules for all ETF investors. Capital gains rates, the wash sale rule (Section 1091), dividend classification, and the NIIT all come from the Internal Revenue Code. Every tax decision you make with ETFs flows through IRS rules first.
Authorized Participants (APs) are the institutional players — firms like Goldman Sachs, JPMorgan, and Citadel Securities — that interact directly with ETF issuers. Their ability to create and redeem shares in-kind is the mechanism that drives tax efficiency. Without APs, ETFs would function like mutual funds.
ETF issuers — Vanguard, BlackRock (iShares), State Street (SPDR), Invesco, and Schwab — design and manage the funds. Vanguard pioneered a unique patent (now expired) that allowed its mutual funds to share a structure with its ETFs, giving even Vanguard mutual fund holders some of the ETF tax benefits. BlackRock’s iShares and State Street’s SPDR families represent the largest ETF lineups in the U.S.
FINRA and the SEC regulate ETFs as securities. The SEC approved the first ETF (SPY) in 1993 under the Investment Company Act of 1940. The SEC’s ETF Rule (Rule 6c-11), adopted in 2019, streamlined the process for launching new ETFs and established the regulatory framework that governs the creation/redemption process today.
The Heartland Advisors Ruling and Tax Law Precedent
While there are few landmark tax cases specifically about ETFs, the broader legal framework governing how in-kind redemptions avoid capital gains comes from Section 852(b)(6) of the Internal Revenue Code. This provision states that a regulated investment company (which includes ETFs) does not recognize gain or loss on the in-kind distribution of securities to a redeeming shareholder.
This is the specific legal authority that makes the entire ETF tax-efficiency machine work. Without Section 852(b)(6), every redemption could trigger a taxable event inside the fund. The provision has been in place for decades, originally benefiting mutual funds, but ETFs are the vehicle that uses it most effectively because all of their primary market transactions flow through the in-kind process.
The IRS has issued private letter rulings confirming this treatment for specific ETF structures. These rulings are not published as formal precedent, but they reinforce the IRS’s consistent position that in-kind creation and redemption transactions are non-taxable events.
FAQs
Are ETFs always more tax efficient than mutual funds?
No. Most equity ETFs are more tax-efficient, but bond ETFs, commodity ETFs, and emerging market ETFs may not be because they sometimes use cash redemptions or derivatives instead of in-kind transfers.
Do I owe taxes on ETF dividends even if I reinvest them?
Yes. Reinvested dividends are still taxable income in the year received. Qualified dividends are taxed at 0%–20%, while non-qualified dividends are taxed at your ordinary income rate.
Can I avoid the wash sale rule by buying an ETF that tracks the same index from a different company?
No. The IRS may consider two funds tracking the same index as substantially identical, even from different issuers. Use a fund that tracks a different index for safety.
Are ETF capital gains taxed differently than stock capital gains?
No. The IRS treats ETF capital gains the same as stock gains. Short-term gains are taxed at ordinary rates; long-term gains are taxed at 0%, 15%, or 20%.
Should I hold all my ETFs in a Roth IRA to avoid taxes completely?
No. Equity ETFs are already tax-efficient in taxable accounts. Roth IRA space is better used for less tax-efficient investments like bond funds, REITs, or actively managed mutual funds.
Do state taxes apply to my ETF gains?
Yes. Most states tax capital gains and dividends as income. Seven states have no income tax. High-tax states like California and New York add significant costs on top of federal taxes.
Is tax-loss harvesting with ETFs legal?
Yes. It is a legitimate and widely used strategy. You sell an ETF at a loss and buy a non-identical replacement. The IRS allows the loss deduction as long as you follow the wash sale rule.
Are actively managed ETFs less tax-efficient than index ETFs?
No. Active ETFs still use the in-kind redemption process. In 2025, only 9% of active ETFs paid a capital gain — far better than the 53% of active mutual funds.
Do I pay taxes on ETF gains inside my 401(k)?
No. Gains inside a traditional 401(k) are tax-deferred. You pay ordinary income tax only when you withdraw money in retirement. Roth 401(k) withdrawals are tax-free.
Can the IRS change the rules and make ETFs less tax-efficient?
Yes. Congress could modify Section 852(b)(6) of the Internal Revenue Code or change how in-kind transactions are treated. No current legislation proposes this, but the possibility exists.
