How NEOS ETFs SPYI, QQQI, and IWMI Achieve Tax Efficiency

NEOS ETFs like SPYI, QQQI, and IWMI achieve tax efficiency through three stacked mechanisms: they write options on broad market indexes that qualify as Section 1256 contracts (taxed 60% long-term and 40% short-term regardless of holding period), they harvest realized losses inside the portfolio to shrink the net gain that flows through to shareholders, and they classify a meaningful portion of each monthly distribution as return of capital, which defers tax by reducing your cost basis instead of counting as current income. The result is that a distribution rate that would be taxed as ordinary income in a typical option-income fund can end up taxed at blended capital gains rates, or not taxed at all until you sell.

The 60/40 Rule on Index Options

The starting point is the type of option each fund writes. Instead of selling calls on individual stocks or on ETFs like SPY, QQQ, or IWM, these funds sell calls on the underlying indexes themselves (the S&P 500, Nasdaq-100, and Russell 2000). Options on broad-based indexes are classified as nonequity options under federal tax law, which makes them Section 1256 contracts.

That classification triggers two automatic rules. Every open Section 1256 contract is marked to market on the last business day of the tax year, meaning it’s treated as sold at fair market value whether the fund actually closed it or not. And every gain or loss from these contracts is split 60/40: 60% long-term capital gain, 40% short-term, no matter how briefly the contract was held.¹

The rate difference matters. Long-term capital gains top out at a 20% federal rate; short-term gains and ordinary income top out at 37%.² For a top-bracket investor, the blended maximum on Section 1256 gains works out to roughly 26.8% rather than 37%. Funds writing options on individual stocks or on equity ETFs don’t get this treatment. Their option gains are short-term and fully ordinary. That gap is the single structural reason NEOS uses index-level derivatives.

Wash Sale Rules Don’t Apply

Section 1256 contracts carry a second, less-publicized advantage: the IRS wash sale rules don’t reach them.³ With ordinary securities, selling at a loss and repurchasing a substantially identical position within 30 days disallows the loss. With index options, the fund can close a losing position and reopen a near-identical one the same day without losing the deduction.

Internal Loss Harvesting

The 60/40 split lowers the rate on gains. Internal loss harvesting lowers the amount of gain that reaches shareholders in the first place. NEOS managers actively look for positions carrying unrealized losses and sell them to offset gains generated by the option overlay. The offsetting happens inside the fund, so the number reported on the fund’s annual tax filings is a smaller net figure than the gross activity would suggest.

This is where the wash sale exemption pays off in practice. Because losing index option positions can be closed and replaced immediately without losing the tax deduction, loss harvesting becomes a daily operational tool rather than a year-end scramble. The smaller the net realized gain the fund reports, the smaller the taxable slice of your distribution.

Return of Capital and Cost Basis

Look at any 1099-DIV for a NEOS fund and you’ll see part of the distribution classified as return of capital. This is not a warning sign on its own. Under federal tax law, a distribution counts as a taxable dividend only to the extent it comes from the fund’s current or accumulated earnings and profits.⁴ Anything paid beyond that reduces your cost basis in the shares instead of appearing as income for the year.⁵

An example. You buy shares at $50. You receive $2 per share classified as return of capital during the year. You owe nothing on that $2 now. Your adjusted basis drops to $48. When you eventually sell, the sale price is measured against $48, not $50, so the deferred amount reappears as capital gain. If you’ve held longer than a year, that gain is long-term. The mechanism converts what would have been current ordinary income into deferred long-term capital gain.

When Basis Reaches Zero

The deferral has a ceiling. The IRS does not allow negative basis. Once return-of-capital distributions have driven your basis to zero, any additional return-of-capital payment is treated as gain from the sale of property and becomes taxable in the year received.⁵ For shares held longer than a year, that gain is long-term. Investors holding these funds for many years in taxable accounts should track how quickly cumulative return-of-capital distributions are eroding the basis, because the deferral benefit ends when the basis is exhausted.

What the Structure Doesn’t Shield: the 3.8% NIIT

High earners face an additional layer that the 60/40 split does not eliminate. The Net Investment Income Tax adds a 3.8% surtax on the lesser of net investment income or the amount by which modified adjusted gross income exceeds $200,000 for single filers, $250,000 for joint filers, and $125,000 for married filing separately.⁶ Capital gains, dividends, and interest all count as net investment income, and Section 1256 gains are no exception.

If your income clears the threshold, the effective top rate on the long-term portion climbs to 23.8% and the short-term portion to 40.8%. These thresholds have not been indexed for inflation, so more filers cross them each year. The tax structure inside the fund is doing real work, but it doesn’t make the distributions invisible to NIIT.

Trade-Offs That Affect After-Tax Return

Tax efficiency only matters if the fund is actually producing a return. Writing calls on an index generates premium income but caps participation in rallies above the strike price. Over the decade ending in mid-2026, the Cboe S&P 500 BuyWrite Index captured only about 63% of the S&P 500’s total upside. During the recovery after the March 2020 crash, systematic covered-call strategies captured roughly half the rebound. In a strong bull market, that opportunity cost can outweigh the tax savings.

The subtler issue is NAV erosion. Every distribution, regardless of its tax label, comes out of the fund’s net asset value. If the fund’s total investment return doesn’t keep up with the distributions being paid, NAV drifts lower, and a headline yield of 12% on a shrinking NAV produces smaller dollar payouts over time. Return of capital is not inherently destructive, but it can be. The check to run is whether total return (share price change plus distributions received) is positive over your holding period, not whether the monthly payment kept arriving.

What Shows Up at Tax Time

Your brokerage sends a Form 1099-DIV. Box 3 reports nondividend distributions, and that number is the return of capital for the year — the amount by which you reduce your cost basis.⁷ Most brokerages adjust the basis automatically, but the adjustment can get lost when shares transfer between accounts or across brokers, so verify it.

The 60/40 calculation on Section 1256 contracts lives on Form 6781. The fund handles this at the entity level; you generally don’t file the form yourself for gains generated inside an ETF. Line 8 carries 40% of the net gain to the short-term column of Schedule D, line 9 carries 60% to the long-term column, and the results flow through to your 1099.³

Keep your own record of cumulative return-of-capital distributions and adjusted basis, especially if you hold these funds for years. A spreadsheet updated once a year when the 1099-DIV arrives is enough. When you eventually sell, the difference between your original purchase price and your adjusted basis can amount to thousands of dollars in capital gain you may not have anticipated. SPYI, QQQI, and IWMI all use the same tax-management approach on their respective indexes (S&P 500, Nasdaq-100, and Russell 2000), so the reporting looks the same across the lineup.⁸⁹
