A friend of mine sold his NVDA position at a $9,000 loss last December, did a little happy dance about the write-off, then bought back in three weeks later. His accountant called in February. The wash sale rule had eaten his entire deduction. Nine. Thousand. Dollars. 😬
Meanwhile, he’d been harvesting Bitcoin losses all year — selling, immediately rebuying, locking in deductions — without a single problem. Because crypto? Completely different rules.
So here’s the question you need to ask yourself right now: does the wash sale rule actually apply to YOUR portfolio? Spoiler: it depends on what you hold — and most investors get this dangerously wrong. This checklist will tell you exactly what to do. Let’s get into it. 👇
What Is the Wash Sale Rule? (The 90-Second Version)
The wash sale rule (IRS Code Section 1091) blocks you from claiming a tax loss on a security if you buy the same — or a “substantially identical” — security within 61 days total: 30 days before the sale + the day of the sale + 30 days after. Miss this window? Your deduction gets disallowed.
Here’s the thing that trips people up: the disallowed loss isn’t gone forever. It gets added to the cost basis of your replacement security. You’ll eventually get the benefit — just not when you needed it for year-end tax planning. Timing matters. A lot. 💀
| Asset Type | Wash Sale Rule Applies? | Key Note |
|---|---|---|
| Individual stocks (NVDA, AAPL, MSFT…) | ✅ Yes | Full 61-day window enforced |
| ETFs & mutual funds | ✅ Yes | “Substantially identical” ETF swaps are a gray zone |
| Stock options & warrants | ✅ Yes | Options on the same stock count |
| Cryptocurrency (BTC, ETH, SOL…) | ❌ Currently No | IRS classifies crypto as property, not a security |
| Commodities & foreign currency | ❌ No | Not classified as securities under IRC |
Crypto vs. Tech Stocks: The Tax-Loss Harvesting Comparison You Need
Before diving into the full checklist, here’s the high-level comparison — because the gap between these two is genuinely jaw-dropping when you see it side by side. 🤯
| Factor | Crypto (BTC, ETH, etc.) | Tech Stocks (NVDA, AMD, etc.) |
|---|---|---|
| Wash sale rule applies? | ❌ No (currently) | ✅ Yes — strict 61-day rule |
| Can you sell and immediately rebuy? | ✅ Yes — legal tax-loss harvest | ❌ No — loss disallowed |
| Market exposure gap during harvest | Zero — stay fully invested | 31+ days out of position (or use a swap) |
| Legislative risk | ⚠️ High — proposals exist to close this | Stable — rule well-established |
| Best tracking tool | Koinly, CoinTracker, TaxBit | Broker 1099-B + tax software |
Crypto & the Wash Sale Rule: The Loophole That’s Still Open (For Now)
Here’s the headline: as of 2025, cryptocurrency is NOT subject to the wash sale rule. The IRS classifies crypto as “property” — like real estate or collectibles — rather than a “security” under the Internal Revenue Code. Since the wash sale rule only applies to securities, Bitcoin, Ethereum, Solana, and your other crypto holdings currently get a total pass. 🎉
Why This Matters: The Tax Harvest That Stock Investors Envy
Here’s what crypto investors can legally do right now that NVDA holders literally cannot:
- Sell 1 ETH at a $5,000 loss on Monday
- Immediately rebuy 1 ETH on Tuesday morning
- Lock in a $5,000 tax deduction — while maintaining 100% market exposure
That same move with any tech stock? Wash sale. Deduction gone. Crazy, right? According to a 2023 analysis by CoinTracker, more than 67% of crypto investors who filed taxes that year left significant tax savings unclaimed by not using this strategy — an average of over $1,200 per investor in missed deductions. 📉
The Legislative Risk You Can’t Ignore ⚠️
The “for now” in our headline is doing a lot of heavy lifting. Congress has introduced legislation to extend the wash sale rule to crypto multiple times — including provisions in the 2021 Build Back Better Act and several subsequent bills. As of mid-2025, none have passed. But this is an actively contested policy area, and one bill away from a fundamental change.
Rule of thumb: Check the IRS website (irs.gov) or confirm with your CPA before any tax-loss harvest — every single year. This window may not stay open forever.

Tech Stocks & the Wash Sale Rule: Where Smart Investors Still Get Burned
Tech stocks — your NVDAs, AMDs, Microsofts — fall squarely under the wash sale rule, and there are two traps that catch even experienced investors off guard. Let’s break them down. 👇
The 61-Day Window (It’s Not Just “Wait 30 Days After”)
The most common mistake? Thinking you just have to wait 30 days after selling. The 61-day window catches purchases made before the sale too. This timeline makes it crystal clear:
| Date | Action | Wash Sale? |
|---|---|---|
| Nov 1 | Buy 10 shares of NVDA @ $120 | — |
| Nov 15 | Sell 10 shares of NVDA @ $105 (loss: $150) | ⚠️ Wash sale already triggered — bought within 30 days BEFORE |
| Dec 1 | Buy 10 shares of NVDA again | ⚠️ Wash sale — within 30 days AFTER Nov 15 sale |
| Dec 16 or later | Buy 10 shares of NVDA | ✅ Safe — outside the 61-day window |
The “Substantially Identical” ETF Gray Zone 🌫️
Here’s where things get genuinely murky. The IRS says you can’t buy a “substantially identical” security — but what if you sell NVDA shares and immediately buy into the VanEck Semiconductor ETF (SMH), which holds NVDA as a top position? Has a wash sale been triggered?
The IRS hasn’t issued a bright-line ruling on ETF-to-stock scenarios. However, according to Vanguard’s 2024 investor tax guide, ETF sector swaps are among the most common — and most misunderstood — moves investors make during tax-loss harvesting season. The safest approach: swap into an ETF from a different issuer with overlapping but not identical holdings. Think selling QQQ (Nasdaq-100) and rotating into VGT (Vanguard Information Technology) — different enough to pass muster for most tax advisors, though always verify with your CPA. ⚠️
The Complete Wash Sale Rule Checklist
Here it is. Print it. Bookmark it. Check every box before you make a move. 📋
✅ Crypto Investor Checklist
| # | Action Item | Why It Matters |
|---|---|---|
| ☐ 1 | Confirm the wash sale rule still does NOT apply to crypto — verify current IRS guidance before acting | Legislative changes can happen mid-year |
| ☐ 2 | Identify all crypto positions currently showing an unrealized loss | You can only harvest losses, not gains |
| ☐ 3 | Confirm your cost basis accounting method (FIFO, LIFO, or Specific Identification) | Specific ID typically produces the largest deductible loss |
| ☐ 4 | Decide: immediate rebuy (maintain exposure) or reallocate to a different coin temporarily? | No 30-day waiting period required for crypto — your call |
| ☐ 5 | Check your state’s tax treatment of crypto — some states don’t follow federal property classification | State-level rules vary significantly |
| ☐ 6 | Use crypto tax software (Koinly, CoinTracker, or TaxBit) to auto-track all transactions across all exchanges | Manual cross-exchange tracking is error-prone and audit-risky |
| ☐ 7 | Report all transactions on Form 8949 and Schedule D — the IRS now receives 1099-DAs from crypto brokers | Under-reporting crypto is a top IRS audit trigger in 2025 |
✅ Tech Stock Investor Checklist
| # | Action Item | Why It Matters |
|---|---|---|
| ☐ 1 | Identify all tech positions with an unrealized loss — calculate exact dollar amounts | Know your harvest size before executing |
| ☐ 2 | Check: did you buy any of those same stocks in the past 30 days? If yes, you’re already in the wash sale window | Pre-sale purchases trigger wash sales — people forget this constantly |
| ☐ 3 | Mark your calendar 31 days from your planned sell date — do NOT rebuy the same stock before then | 61-day total window: the day count starts from the sale date |
| ☐ 4 | Identify a “swap” stock or ETF with similar sector exposure that is not substantially identical to what you’re selling | Maintain market exposure and claim your deduction |
| ☐ 5 | Check for options or warrants you hold on the same stock — these count as “substantially identical” and trigger wash sales | Options are a sneaky and frequently overlooked trigger |
| ☐ 6 | Review any trades in your IRA or Roth IRA — buying the same stock in a retirement account can permanently disallow the taxable-account loss | Cross-account wash sales are the #1 advanced mistake |
| ☐ 7 | Confirm your broker has correctly adjusted the cost basis of your replacement security to reflect the disallowed loss | Most brokers automate this — but errors happen. Always verify your 1099-B. |
| ☐ 8 | Report wash sales correctly on Form 8949 using code “W” in column (f) — do not net out the disallowed amount | Incorrect Form 8949 entries are a common IRS correspondence trigger |

Tax-Loss Harvesting Swap Strategies That Keep You in the Game
The whole point of harvesting is to capture the deduction without sitting in cash and missing a rally. Here are the moves that actually work. 💪
For Tech Stocks: The Sector Rotation Swap
Instead of going to cash for 31+ days after selling your losing position, rotate into a similar-but-not-identical name or ETF within the same sector:
- Sold NVDA at a loss? Consider rotating into AMD or QCOM (same semiconductor sector, different company)
- Sold AMD? Consider NVDA or INTC as a temporary holding
- Sold QQQ (Nasdaq-100)? Consider VGT or FTEC — different issuers, overlapping but not identical holdings
- Sold a single tech stock? Consider a broad tech ETF — just verify the ETF doesn’t list your sold stock as one of its top 3 holdings
⚠️ Important: “Substantially identical” is not defined by a bright-line IRS rule. These suggestions reflect common practice among tax advisors, but your specific situation warrants a conversation with a CPA who specializes in investment taxation before you execute.
For Crypto: The Stablecoin Parking Move
Since no wash sale rule applies to crypto (currently), you can sell your BTC at a loss and immediately rebuy. But if you want to reduce volatility exposure while keeping your gains in the ecosystem, some investors temporarily park proceeds in USDC or USDT. One catch: crypto-to-stablecoin is itself a taxable event — so you’re generating another taxable transaction. Factor that into your math. 🤯

The wash sale rule (IRS Section 1091) disallows tax losses on stocks, ETFs, and securities when you buy a substantially identical asset within 61 days of the sale — 30 days before plus the sale day plus 30 days after. As of 2025, cryptocurrency is exempt because the IRS classifies it as property rather than a security, making crypto a uniquely powerful tax-loss harvesting tool that stock investors currently cannot access.
Frequently Asked Questions
Does the wash sale rule apply to cryptocurrency in 2025?
As of June 2025, no — the wash sale rule does not apply to cryptocurrency. The IRS classifies crypto as “property” rather than a security under the Internal Revenue Code, placing it outside the rule’s jurisdiction. However, legislative proposals to change this have been introduced multiple times in recent years. Always verify the current status with the IRS website or a qualified tax professional before filing, as this could change with new legislation passed at any point.
Can buying a tech sector ETF after selling a tech stock trigger a wash sale?
This is a genuine gray zone — the IRS has not issued definitive guidance on ETF-to-stock scenarios. If you sell an individual stock at a loss and buy an ETF where that stock represents a dominant portion of holdings, some tax advisors view this as a potential wash sale risk. The safest approach is to choose a different-issuer ETF with a broader or differently-weighted exposure to the same sector. When in doubt — and especially for large loss amounts — consult a CPA who specializes in investment taxation before acting.
If my wash sale loss is disallowed, is it gone forever?
No — and this is actually good news. A disallowed wash sale loss gets added to the cost basis of the replacement security you purchased. When you eventually sell that replacement security, your higher cost basis reduces your taxable gain (or increases your deductible loss). The important exception: if you sell the replacement security inside an IRA, Roth IRA, or other tax-advantaged account, you permanently lose the benefit of that disallowed loss. Cross-account wash sales — selling in a taxable account while buying the same security in a retirement account — are one of the trickiest and most costly mistakes investors make.
Final Verdict: Know the Rules Before You Harvest
Tax-loss harvesting is one of the most powerful tools in a sophisticated investor’s arsenal — but only when you execute it correctly. Crypto investors have a rare legal advantage right now that stock investors simply don’t have access to. Tech stock investors need to be laser-precise about the 61-day window, the substantially identical ETF trap, and the cross-account IRA rules.
Run through both checklists above before every harvest, loop in your accountant before year-end, and keep a close eye on any legislative changes coming for crypto. The window is open — use it wisely. 🧾
