Wash Sale Rule 2026 — IRS Explained, 30-Day Window, Crypto Loophole, Tax Strategies
⚡ Read this before you open your next trade
**Wash sale rule (IRS Section 1091)** = US tax rule disallowing tax loss deduction if you buy back same/substantially identical security within **30 days before or after** selling at loss. Total **61-day window** (30 before + sale day + 30 after). **Purpose**: prevent tax loss harvesting via temporary sales. **Example**: 1) Buy 100 AAPL at $200 = $20,000 cost basis. 2) AAPL drops to $150. Sell 100 AAPL = $5,000 realized loss. 3) Buy 100 AAPL at $155 within 30 days. 4) **WASH SALE TRIGGERED**. $5,000 loss DISALLOWED for current tax year. 5) $5,000 added to new cost basis ($15,500 + $5,000 = $20,500 effective). 6) Loss recognized when finally sell new shares (no permanent disallowance, just deferred). **What counts "substantially identical"**: 1) Same stock (AAPL → AAPL). 2) Same options (AAPL options → AAPL options). 3) Different share class generally NOT (Berkshire A vs B = different). 4) Different ETFs tracking same index = GRAY AREA (SPY vs VOO usually OK, SPY vs SPDR S&P 500 = wash sale). **CRYPTO EXEMPTION**: Crypto NOT classified as security by IRS. Wash sale rule **DOES NOT APPLY** to crypto (yet — proposed legislation may change). Sell BTC at loss, buy back next minute = LOSS DEDUCTIBLE. **Tax strategies for wash sale**: 1) **Wait 31 days**: simple, ensures no wash sale. 2) **Buy similar but not identical**: SPY → IVV (S&P 500 vs S&P 500 = wash sale), SPY → IWM (S&P 500 vs Russell 2000 = NOT wash sale). 3) **Use different account**: spouse's IRA = STILL wash sale (counts as you). Spouse's taxable account = wash sale. 4) **Tax loss harvest year-end**: sell losing positions December 1, wait until February to re-enter. **For Polish traders**: Wash sale rule = US ONLY. **Polish tax law** does NOT have wash sale equivalent. Polish traders can: 1) Sell BTC at loss December 31. 2) Buy back January 1. 3) Loss deductible against gains on PIT-38. 19% Belka. **Polish loss carryforward**: Realized losses carry forward 5 years against gains. **Polish strategy**: Year-end loss harvesting = optimize Belka tax. Take profits at year start, take losses at year end. **For US-Polish dual residents**: complex. Get tax advisor. May trigger US wash sale even with Polish broker. This 2026 guide covers: wash sale mechanics, crypto exemption, US vs Polish, tax strategies, [Vantage](https://vigco.co/la-com-inv/CE3HlGvG) tax-efficient setup.
Polish Tax Strategies (No Wash Sale)
Polish trader advantage: NO wash sale rule. Tax loss harvesting trivial. Strategy 1: Year-end harvesting: 1) December 20: review losing positions. 2) Sell losers to realize losses. 3) January 2: buy back same positions if still believe in them. 4) Losses offset Belka 19% on gains in PIT-38. 5) Save 19% × loss amount in tax. Strategy 2: Loss carryforward: 1) Realize $10,000 loss in 2026. 2) No gains to offset = $10,000 loss carries forward 5 years. 3) Realize $20,000 gain in 2027 = offset $10,000 = pay 19% only on $10,000 net = $1,900 tax (vs $3,800 without harvest). Strategy 3: Combine with Vantage CFDs: 1) Vantage forex/gold trading = capital gains, PIT-38, 19% Belka. 2) Same loss harvesting rules apply. 3) End year, realize losses, restart positions January.
