A widely held fixed investment trust, or WHFIT, is a passive investment vehicle that holds a locked portfolio of assets and passes all of its income, expenses, and gains straight through to investors for tax purposes. The trust pays no federal income tax itself. Instead, if you own units, you report your proportionate share of every dollar the trust earned or spent on your own return, which makes annual filing meaningfully more involved than holding a mutual fund or a single stock.
What Qualifies a Trust as a WHFIT
Two conditions have to be met under Treasury Regulation §1.671-5.1eCFR. 26 CFR 1.671-5 – Reporting for Widely Held Fixed Investment Trusts
The trust has to be fixed. Once it’s established with a defined set of assets, the trustee cannot actively trade, swap securities, or rebalance. The assets sit until they mature, are called, or the trust reaches its termination date. If the trustee has the power to vary investments, Treasury Regulation §301.7701-4(c) can reclassify the whole thing as a business entity taxed as a corporation, which defeats the pass-through structure entirely.2Internal Revenue Service. Notice 2010-4 – WHFIT Transition Guidance
The trust also has to be widely held, which is satisfied when at least one interest is held by a middleman. A middleman is any intermediary holding trust units on behalf of a beneficial owner: custodians, brokers holding shares in street name, and nominees.1eCFR. 26 CFR 1.671-5 – Reporting for Widely Held Fixed Investment Trusts Because interests move through brokerages and custodians, the trustee often has no direct line to the actual owners, and the specialized reporting rules exist to bridge that gap.
What Kinds of Investments Are WHFITs
Regulations sort WHFITs into two categories, and the one you hold changes what your tax paperwork looks like.
Widely Held Mortgage Trusts
WHMTs hold pools of mortgage-backed pass-through securities. The most common are pools established through Fannie Mae, Freddie Mac, and Ginnie Mae, along with trusts that invest in regular-interest REMICs.3Federal Housing Finance Agency. About Fannie Mae and Freddie Mac They pass through both interest income and return-of-principal payments as mortgages in the underlying pool are paid down or refinanced. That constant drip of principal payments is what makes WHMT reporting particularly tedious, since each payment forces a cost basis adjustment.
Non-Mortgage WHFITs
NMWHFITs cover everything else. Unit investment trusts holding a basket of stocks or bonds fall here, as do commodity trusts like the SPDR Gold Trust (GLD). GLD is treated as a grantor trust whose income and expenses flow directly to shareholders. NMWHFITs can hold equities, debt instruments, commodities, or royalty interests. They skip the mortgage-specific complications but still require detailed pass-through reporting of income, expenses, and any gains from asset dispositions inside the trust.
How the Pass-Through Actually Taxes You
A WHFIT is a grantor trust under Section 671 of the Internal Revenue Code. When a person is treated as the owner of a trust, all items of income, deductions, and credits attributable to the trust are included in that person’s own taxable income.4Office of the Law Revision Counsel. 26 USC 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners The trust is effectively invisible for tax purposes. Each investor, called a Trust Interest Holder (TIH), owns a proportionate slice of every asset and must report their share of everything the trust earns or spends.
The trust files no income tax return and pays no tax. Every dollar of interest, every dividend, every capital gain from asset sales inside the trust lands on the TIH’s personal return. Trust expenses get allocated too, but as you’ll see below, allocation is not the same thing as deductibility.
The Tax Documents You’ll Receive
WHFIT investors get two things each year: a set of Forms 1099 and a supplemental written tax information statement.
The 1099s may include Form 1099-INT for interest, Form 1099-DIV for dividends, Form 1099-B for proceeds from asset sales inside the trust, and Form 1099-OID for original issue discount if the OID attributable to you exceeds $10 for the year.5Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID
The supplemental statement is where the detail lives. It breaks down every item of income, expense, and credit allocated to you, including OID calculations, non-pro-rata principal payments, and details of any asset sales within the trust. Because of the allocation work involved, that statement is due by March 15, later than the standard 1099 deadline.5Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID For many WHFIT investors, that late arrival is the reason to file for an extension rather than a rushed April return.
You’ll typically receive these from your brokerage, not the trustee. The trustee sends data to the middleman, and the middleman folds it into your consolidated statement.
Gross-Up Reporting and Phantom Income
A quirk of WHFIT reporting is the gross-up method for expenses. Trust expenses like trustee fees and administrative costs are not netted against income before you see your share. The trustee reports the full gross income to you and separately reports your allocated share of expenses. You then report the larger gross figure and try to claim the expenses as a separate deduction.
The catch: under current law, you usually can’t claim them. Trust administrative expenses allocated to an individual WHFIT investor are miscellaneous itemized deductions. Historically these were deductible only above a 2% adjusted gross income floor, which most retail investors never cleared. The 2017 Tax Cuts and Jobs Act then suspended miscellaneous itemized deductions entirely, and current law at Section 67(h) provides that no miscellaneous itemized deduction is allowed for any taxable year beginning after December 31, 2017, with no sunset.6Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions
The practical effect is that you’re taxed on the trust’s gross income but cannot deduct your share of its administrative expenses. The taxable income on your 1099 can be higher than the cash you actually received. For investors with sizable WHFIT positions, that gap is a persistent phantom income problem, and it won’t change without a future act of Congress.
Tracking Cost Basis
When the trust sells an underlying asset, you recognize your proportionate share of the capital gain or loss on Schedule D of Form 1040. The supplemental statement gives you the date of sale, gross proceeds, and the percentage of the trust asset sold.
For WHMT investors, the ongoing stream of principal payments requires continuous downward adjustments to your cost basis. Skip those adjustments and you’ll overstate your basis when you eventually sell, which understates the gain and sets you up for an unpleasant correction later. The supplemental statement is what you keep in the file.
What Happens When the Trust Ends
Every WHFIT has a specified termination date, which is part of the fixed requirement. When it winds down, the remaining assets are sold and the proceeds distributed to unitholders. That final distribution is treated as a sale of your proportionate share of the underlying assets. Your capital gain or loss is the difference between the proceeds you receive and your adjusted basis in the units.
For long-held WHMT units, the adjusted basis can be far lower than what you originally paid, because every principal payment along the way reduced it. An investor who paid $10,000 for units and received $3,000 in principal payments over the trust’s life has an adjusted basis of $7,000. If the trust liquidates and returns $7,500, that’s a $500 capital gain, not a $2,500 loss. Investors who haven’t tracked their basis adjustments year by year tend to find this out the hard way when the final statement arrives.
