Which BTC ETFs trigger wash sale?

TLDR

In the US, selling a spot Bitcoin ETF at a loss and rebuying the same or a substantially identical Bitcoin ETF within 30 days can trigger the wash-sale rule.

1. The rule applies to crypto ETFs/ETPs (securities), not to native crypto held directly, per a recent tax explainer.
2. Switching issuers (IBIT, FBTC, ARKB, BITB, GBTC) can still be substantially identical when all track spot BTC.
3. Different tickers rarely avoid wash-sale; substantially identical is broad (think SPY vs VOO) per year-end guidance.

Deep Dive

1. Substantially Identical ETFs

The wash-sale rule disallows a loss if you repurchase the same or a substantially identical security within 30 days. Spot Bitcoin ETFs from different issuers all aim to hold or track spot BTC, so rotating IBIT into FBTC (or ARKB, BITB, GBTC) within 30 days after selling at a loss can be treated as substantially identical.

• Recent coverage explicitly distinguishes native crypto (property) from ETFs (securities) and notes wash-sale applies to the ETF category, including similar Bitcoin funds across issuers video overview.
• The different ticker workaround has a high bar. Equity analogies (SPY vs VOO) show similar funds likely fail the test, reinforcing that issuer switches may still trigger the rule insight.

2. Native Crypto Is Different (For Now)

Today, the wash-sale rule does not apply to native crypto like Bitcoin (BTC) itself. Investors can sell BTC at a loss and immediately rebuy BTC without triggering wash-sale. This flexibility does not extend to ETFs, which are regulated securities.

• Coverage clarifies that the strategy is unique to native crypto and that wash-sale constraints return when using ETFs/ETPs explainer.

3. Practical Framework

To avoid a wash-sale with BTC ETFs, either wait 31 days before repurchasing the same exposure or choose an instrument that is demonstrably not substantially identical. A miners equity fund or a futures-based crypto fund may differ, but the different enough test is facts-and-circumstances driven.

• Year-end guidance underscores that substantially identical can include funds with different tickers but the same underlying exposure and methodology overview.

Conclusion

Any US spot Bitcoin ETF (e.g., IBIT, FBTC, ARKB, BITB, GBTC) can trigger wash-sale if you sell at a loss and buy the same or a substantially identical BTC ETF within 30 days. Native BTC is not subject to wash-sale today, but ETFs are securities with stricter rules. Confidence: moderate because the IRS has not published ETF-specific substantially identical guidance; verify your plan with a tax professional.
