As cryptocurrencies continue reshaping the financial landscape in 2025, tax compliance has become more critical than ever. Regulators worldwide, especially the IRS in the United States, have expanded reporting requirements and introduced new forms to ensure accurate reporting of digital asset activity.
For both new investors and seasoned traders, understanding how cryptocurrency is taxed can protect you from penalties and optimize your overall tax liability. This guide explains the essentials of crypto taxes in 2025, the forms you need, key deadlines, strategies to manage liabilities, and Bitunix-specific reporting guidance.

Crypto Taxes

Understanding Cryptocurrency Taxation Basics

For tax purposes in the United States, cryptocurrency is treated as property rather than currency. This means that every taxable event, such as selling, trading, or using cryptocurrency to make purchases, must be reported just as you would with stocks or other capital assets.
A taxable event occurs whenever you dispose of cryptocurrency, including:
  • Selling for fiat currency such as USD or EUR
  • Trading one cryptocurrency for another
  • Using cryptocurrency to purchase goods or services
  • Earning income from mining, staking, or rewards
Each of these actions can result in either a capital gain or a capital loss, which must be reported.

What Counts as a Taxable Event?

In the eyes of many tax authorities, including the IRS in the United States, cryptocurrencies are treated as property. This means that standard property tax rules apply to transactions involving cryptocurrencies. A taxable event in the context of crypto occurs whenever you dispose of your cryptocurrency in any way—whether that’s selling it for fiat, trading it for another crypto, or using it to buy goods and services.

Which Tax Forms Are Used for Cryptocurrency?

Tax reporting for cryptocurrency requires different forms depending on the type of activity.
  • Form 8949: Used to list each sale or disposition of crypto. You must include acquisition date, sale date, cost basis, and proceeds for every transaction.
  • Schedule D (Form 1040): Summarizes your overall capital gains and losses, including those from crypto reported on Form 8949.
  • Form 1040: The main U.S. income tax form. It includes the virtual currency question on the first page, requiring all taxpayers to declare if they engaged in digital asset activity.
  • Form 1099 Series:
    • 1099-MISC: Reports staking, referral, or other miscellaneous crypto income.
    • 1099-B: Reports sales of crypto through brokers or exchanges.
    • 1099-DA: Starting in 2025, this form is specifically for digital asset transactions. Some U.S. exchanges will issue it, but overseas exchanges such as Bitunix may not.
  • Schedule C: If you receive crypto as business income, you must report it here.

How to Calculate Crypto Gains and Losses

  1. Identify the Cost Basis This is the original amount you paid for the cryptocurrency, including any fees.
  2. Determine the Fair Market Value This is the value of the crypto in fiat currency at the time of the transaction.
  3. Calculate the Gain or Loss Subtract the cost basis from the fair market value. A positive number is a gain, while a negative number is a loss.

Reporting and Paying Crypto Taxes

Accurate record-keeping is essential for compliance. You should track:
  • The date of each transaction
  • The value of the cryptocurrency in fiat at the time of the transaction
  • The purpose of the transaction (sale, trade, payment)
  • The other party involved, if applicable
You will then use this information to complete Form 8949, summarize totals on Schedule D, and report income on Form 1040.

Necessary Documentation

Accurate record-keeping is fundamental when it comes to cryptocurrencies. For each transaction, you should document

The date of each transaction

Knowing when you bought and sold cryptocurrency is essential for calculating taxes, especially since the duration you hold a crypto asset can affect the tax rate (short-term vs. long-term capital gains).

The value of the cryptocurrency in fiat at the time of the transaction

This information is crucial for determining the fair market value of your crypto when you conduct a transaction. You’ll use this value to calculate gains or losses.

The purpose of the transaction and who the other party was (even if it’s just their wallet address): 

This helps establish the nature of each transaction, whether it was a sale, a trade, or another type of exchange. Knowing the other party’s wallet address can also be important for record-keeping and regulatory compliance.

Strategies for Managing Crypto Taxes

Harvesting Losses

Tax-loss harvesting involves selling crypto at a loss to offset gains from other investments, reducing your taxable income. This strategy requires careful planning to ensure it aligns with tax regulations.

Long-Term Holding

Holding cryptocurrency for more than a year before selling or trading can significantly reduce tax rates due to the favorable rates applied to long-term capital gains.

Utilizing Tax-Deferred Accounts

Consider using tax-advantaged accounts such as IRAs to invest in cryptocurrencies. While the regulations around these investments can be complex, they may offer opportunities for tax-free growth or tax deferral.
