How to Claim Crypto Losses on Your Taxes to Reduce Taxable Gains


Why Claiming Losses Matters for Crypto Taxes

Claiming capital losses on your cryptocurrency investments is an important tax strategy to lower your overall tax liability. Since the IRS treats virtual currencies like bitcoin as property for tax purposes, they are subject to the same capital gains and losses tax rules as stocks and bonds. By properly calculating and claiming your realized crypto losses, you can offset some of your taxable crypto gains to reduce how much you end up owing.

Some key reasons why deducting cryptocurrency losses matters:

  • Reduce Total Taxable Income from Crypto Transactions – Reporting both gains and losses allows you to calculate your net result for the year. If your total capital losses exceed gains, you can use up to $3,000 to lower regular taxable income.
  • Offset Realized Gains from Bitcoin or Other Coins – Losses balance out any long or short-term crypto capital gains, lowering your tax payment. This applies across all coins.
  • Carry Forward Leftover Capital Losses – If your losses exceed the $3K deduction limit and gains offset amount, you can carry forward excess capital losses to future tax years.

Tax Benefits Summary

Tax Benefit Description
Lower Taxable Income Claim up to $3,000 in net losses to reduce taxable income
Offset Gains Deduct losses against any taxable crypto gains
Carry Forward Losses Leftover capital losses can apply to future years

As you can see, recording both crypto gains and losses accurately on your taxes allows you to minimize tax overpayment and keep more of your investment returns.

Rules for Claiming Crypto Losses

While deducting cryptocurrency losses can seem straightforward, there are specific IRS rules around which crypto-related losses actually qualify:

Realized Losses Only

Only “realized” losses from selling, exchanging, or disposing of your cryptocurrency count as deductible losses. This includes:

  • Trading one coin for another
  • Selling crypto for fiat currency like USD
  • Paying for goods/services with crypto (calculated cost basis)

Unrealized losses from just holding coins as they drop in value do not qualify. You must “realize” the loss by completing a taxable transaction.

Short & Long Term Capital Gains Rules Apply

Cryptocurrency losses apply the same capital gains categories as stocks for short and long term:

  • Short – held 1 year or less
  • Long – held over 1 year

Your time holding the coins before selling or exchanging at a loss determines the loss type. Appropriate capital gains tax rates apply based on income.

Loss Deduction Limits

For reducing regular taxable income, you can only deduct:

  • Up to $3,000 in total net capital losses per year
  • Carried forward losses apply in future years

Net loss calculation factors both crypto gains and losses across transactions.

How to Calculate & Track Crypto Tax Losses

In order to claim eligible losses on your taxes, you need to calculate cost basis, transaction times, fair market values, and actual loss amounts.

First-In-First-Out (FIFO) Method

The IRS mandates use of the FIFO (First-In-First-Out) method when tracking cost basis across multiple buys/sells of the same cryptocurrency:

  • Oldest units purchased are tracked and removed first in capital gains calculations
  • Helps properly identify short vs long term holding statuses

FIFO matches purchases to sales for precise tracking of crypto investments over time.

Crypto Tax Software

Given complexities with FIFO calculations, transaction data, and record keeping across crypto buys, sells, trades, and wallet transfers, tax software can help identify, track, and calculate capital losses. Platforms like connect to exchanges via API to auto-import all transaction data and generate needed tax reports per IRS rules.

Benefits of crypto tax software:

  • Automatically track cost basis across purchases
  • Apply FIFO calculations appropriately
  • Import 100% of transaction history across platforms
  • Identify and categorize every capital gain and loss
  • Eliminate manual crypto tax reporting errors
  • Save time come tax season

Claiming Crypto Losses on Tax Return Forms

Once you’ve totaled your eligible capital losses for the tax year, you can claim them on the following IRS forms:

Form 8949

Used to report sales, exchanges, losses, and capital gain distributions for all investment transactions, including cryptocurrency.

Key details to include for crypto losses:

  • Date acquired/sold
  • Proceeds amount (USD value when sold)
  • Cost basis
  • Description of property

Calculated losses get tallied and transferred to Schedule D.

Schedule D

The primary IRS form to calculate and report overall capital gains and losses from investments.

Schedule D categories crypto transactions under “Short-term” and “Long-term” capital gain distributions to tally:

  • Total short-term transactions with losses
  • Total long-term transactions with losses

The total Schedule D losses amount connects to Form 1040 for final tax calculation.

Strategies to Lower Crypto Taxes with Loss Harvesting

One way to maximize crypto loss deductions is through intentional loss harvesting strategies.

This involves selling coins on purpose at an opportune time to realize losses that can offset taxes owed on gains earned throughout the year.

Steps to Harvest Losses

Here is the basic process to harvest and deduct losses:

  1. Review Coin Holdings – Identify coins held at a loss compared to cost basis
  2. Analyze Tax Status – Review current capital gains and tax estimates
  3. Strategically Sell – Sell coin lots at a loss to offset gains; avoid “wash sale” periods
  4. Repurchase Similar Asset – Optional: Buy back similar crypto if still confident in asset class
  5. Report Losses – Claim calculated losses on 8949 + Schedule D

Selling losers purposefully within the rules allows crypto investors to lower capital gains tax bills.

Avoiding Wash Sales

One key aspect of properly executing loss harvesting strategies is avoiding “wash sales” which can invalidate the loss:

  • Wash sale triggers if you buy back “substantially identical” coins 30 days before or after the sale
  • This includes buying forked version or similar cryptocurrencies
  • Disallowed loss gets added to cost basis of replacement coins

Carefully review wash sale rules before claiming any loss deductions.

Common Crypto Loss Scenarios

Beyond simple buy and sell transactions at a lower value, there are a few other ways you may incur deductible crypto losses:

Trading Altcoins, ICOs, or Airdrops

Trading one cryptocurrency for another is a taxable event. You must report any fair market value gains and losses:

  • Trading BTC for ETH would trigger calculable capital gains or losses
  • Swapping altcoins like stablecoins generates tax obligations
  • Transactions with ICO tokens or airdropped coins also matter

Use FIFO cost basis tracking across all trades.

Receiving “Dusted” With Valueless Coins

Getting small amounts of worthless coins sent to wallets can create tax deduction options. This “dusting attack” scenario allows you to:

  • Claim loss equal to fair market value when received
  • Mark coins as $0 cost basis if truly worthless
  • Deduct dust transaction losses from crypto gains

Save dust transaction records for loss reporting.

Losing Access to Old Crypto Purchases

Lost or forgotten about crypto buys from years back can generate capital losses if you no longer have access to the coins. This includes:

  • Abandoned wallets whose keys got lost
  • Sending to wrong address crypto can’t be recovered
  • Getting hacked and having coins stolen

Maintain records showing purchase dates and cost basis of lost cryptocurrency to maximize write-off potential.

Expert Tips to Legally Maximize Crypto Loss Tax Benefits

A few pro tips when managing capital losses on cryptocurrencies:

  • Strategically Move Coins to Establish New Cost Basis – After selling at a loss, transfer remaining coins to new wallets to purchase and hold at current lower cost basis
  • Conduct Loss Harvesting Before Year End – Evaluate investments in late Q4 and realize any losses prior to Dec 31 tax year cutoff
  • Consult Licensed Crypto CPA – Work directly with crypto tax expert to identify best loss harvesting opportunities while avoiding IRS audit triggers


Claiming eligible cryptocurrency capital losses is an important piece of legally minimizing tax obligations from bitcoin and other coin investments. Make sure to accurately track and record all realized losses using acceptable methods like FIFO. Strategically offsetting gains with deductions can help crypto investors maximize after-tax returns and build long term wealth. Work with a cryptocurrency tax professional to ensure you fully benefit from loss reporting while staying compliant.
