The Trap

The PFIC Trap on Inherited Korean Funds

In Brief

Virtually all Korean mutual funds and ETFs are PFICs under US tax law. The default IRC §1291 treatment taxes gains at the top 37% rate plus an interest charge accruing back years. US heirs who keep them can owe $50,000-$150,000 in unnecessary tax. Best practice: dispose within one year.

What Is a PFIC?

A Passive Foreign Investment Company is a foreign corporation where 75%+ of income is passive or 50%+ of assets produce passive income. Korean mutual funds (펀드), ETFs (TIGER, KODEX, KBSTAR), and fund-form REITs all qualify. Direct Korean stocks (e.g., individual Samsung shares) are not PFICs.

The §1291 Disaster (Default Regime)

Without an election, gains and "excess distributions" are allocated across the entire holding period, taxed at the maximum ordinary rate (37%) for each year, with a compounding interest charge (~8%) added from each prior year. Even with stepped-up basis from inheritance, the §1291 mechanism can still apply.

Why Elections Usually Don't Help

QEF election: requires an Annual Information Statement that Korean funds almost never provide
Mark-to-Market: only for "marketable" funds; Korean ETFs may qualify, mutual funds usually don't

The Disaster Math

A US heir inherits a ₩500M Korean equity fund (parent held 15 years). Keep it 5 years, then sell: under §1291, allocated over 20 years at 37% + interest → estimated $80,000-$120,000 US tax. Sell within 1 year instead: stepped-up basis protects most value → estimated $0-$2,000. The difference: $80,000+ saved.

Form 8621: Annual Filing

Each US person owning PFIC shares files Form 8621 annually. There's no specific late-filing penalty, but the statute of limitations doesn't run until filed — creating indefinite audit exposure.

The Action Plan

Inventory all Korean fund holdings (assume all are PFICs)
Dispose within the first year
Reinvest in US-compliant vehicles or direct Korean stocks
