Cleaning Up a PFIC Before Making a Sec 1296 MTM Election

Watch on YouTube

Here’s a full worked MTM example showing the first-year §1291 coordination doing the cleaning, then clean §1296 years afterward.
Numbers are illustrative and rounded; the interest-charge figures especially are ballpark because the real computation compounds daily at the §6621 rates.

Facts

• Client acquired the PFIC stock on 1/1/2019 for $100,000. Never filed Form 8621, no QEF or MTM election, so it’s a §1291 fund.
• First year electing §1296 MTM is TY 2022.
• FMV on 12/31/2022 is $180,000.

Year 1 (TY 2022) — The Coordination / “Cleaning” Year

The §1296 mark is FMV over adjusted basis on the last day of the year: $180,000 − $100,000 = $80,000 gain. Under §1296(j) / Treas. Reg. §1.1296-1(i), because this stock was a §1291 fund, that first-year mark is treated as an excess distribution under §1291(a) and thrown into the interest-charge machinery. So it does not just land as ordinary MTM income — it gets allocated ratably across the holding period (Part V mechanics, §1291(a)(1)(A)).

Holding period is 2019–2022 (4 years). Allocating $80,000 ratably gives $20,000 per year:

The three prior-year slices ($22,200 of tax) are the deferred-tax amount under §1291(c)(2), and each carries a §1291(c)(3) interest charge compounded from that year’s original return due date to 4/15/2023. Illustratively that interest might run on the order of $2,500–$3,500 total across the three years — but you’ll need the actual §6621 daily-rate computation for the real number. The current-year $20,000 slice is ordinary income with no interest charge.

On the form: §1296 election checked in Part II, the first-year mark run through the §1291 computation feeding Part V, interest charge flowing to the return.

Basis Reset (This Is The Actual “Cleaning”)

Under §1296(b), the inclusion increases basis: $100,000 + $80,000 = $180,000. The pre-election appreciation has now been taxed through §1291 and folded into basis. From here forward the §1291 taint is resolved and you’re in a clean §1296 regime.

Years 2+ — Clean MTM Under §1296, No More §1291

Now it’s ordinary MTM gain/loss under §1296(c), reported in Part IV, no allocation, no interest charge.

The 2024 loss is allowed because §1296(a)(2) permits MTM losses only up to “unreversed inclusions” (§1296(d)) — cumulative prior MTM inclusions net of prior allowed losses. Before the 2024 loss, unreversed inclusions = $80,000 (2022) + $30,000 (2023) = $110,000, so the full $20,000 loss clears easily and is ordinary (§1296(c)(2)).

Basis tracks under §1296(b): $180,000 + $30,000 (2023 inclusion) − $20,000 (2024 allowed loss) = $190,000, which ties to the 12/31/2024 FMV, as it should.

The One-Line Summary

The $80,000 first-year mark is the only amount that ever touches §1291 and the interest charge. It cleanses the pre-election gain via §1296(j), steps basis up to FMV, and every year after is plain-vanilla §1296 ordinary gain/loss in Part IV — no more allocation, no more interest charge.

Sections in play: §1296(a)–(d) (MTM inclusion, loss limit, basis, unreversed inclusions), §1296(c) (character), §1296(j) + Reg. §1.1296-1(i) (the first-year §1291 coordination), and §1291(a)–(c) (the excess-distribution/interest-charge computation that runs on that first

Here’s the key point on “purging”: for MTM there is generally no separate purging (prior year) election the way there is for QEF.
The purge is built into the coordination rule.
