Cryptocurrency Tax Preparation: Step-by-Step for Businesses and Individuals

Crypto Startup September 03, 2025

Introduction
As the adoption of cryptocurrencies grows, both businesses and individuals face increasingly complex tax filing requirements. For investors and companies involved in digital assets, preparing taxes properly is crucial to ensure compliance, avoid penalties, and optimize tax outcomes. Cryptocurrency tax preparation involves tracking transactions, determining tax obligations, and applying strategies to minimize liabilities. This step-by-step guide will walk you through the essential tasks required for preparing crypto taxes in 2025.


1. Step 1: Gather Your Crypto Transaction Data
The first step in tax preparation is gathering detailed records of all your cryptocurrency transactions. This includes:
Buy and Sell Transactions: Record every purchase, sale, or exchange of crypto assets.
Staking and Mining Rewards: Include any rewards received for mining or staking crypto.
Airdrops and Forks: Document any tokens received as airdrops or as a result of forks.
Transfers and Withdrawals: If you transferred or withdrew crypto from exchanges or wallets, track these movements.

Use crypto tax software or manual record-keeping to ensure accuracy. Keep in mind that tax authorities may require transaction history for up to 5–7 years.


2. Step 2: Determine the Nature of Your Crypto Transactions
Each type of transaction has different tax implications:
Capital Gains or Losses: Selling or trading crypto typically results in capital gains or losses. You must calculate the difference between the selling price and the cost basis of the asset.
Income from Mining and Staking: Rewards from mining or staking are treated as ordinary income at the fair market value when received.
Airdrops and Forks: These are usually considered taxable income at the moment they are received, with their fair market value as income.
Gifts and Donations: If you’ve given or received crypto as gifts, they may be exempt from taxes depending on the amount and jurisdiction.

Clarifying the nature of each transaction will ensure they are reported correctly.


3. Step 3: Calculate Your Cost Basis and Fair Market Value
To determine your gains or losses, you need to calculate your cost basis (the price you paid for the crypto) and the fair market value at the time of the transaction:
Crypto-to-Crypto Transactions: If you exchanged one crypto for another, you need to calculate the fair market value of the crypto you received at the time of the transaction.
Crypto-to-Fiat Transactions: The value of crypto in fiat currency (USD, EUR, etc.) must be tracked for tax purposes.
Record Keeping: Maintain detailed records of dates, amounts, and exchange rates to calculate cost basis correctly.

There are different methods for calculating cost basis (FIFO, LIFO, HIFO), and each can affect your tax liability. Ensure you use a consistent method for all transactions.


4. Step 4: Report Your Crypto Gains, Losses, and Income
Capital Gains and Losses: Report your crypto capital gains and losses on forms like IRS Form 8949 (U.S.) or your local equivalent. Ensure you classify your gains as short-term (held for less than a year) or long-term (held for more than a year).
Income from Mining and Staking: Report mining or staking rewards as ordinary income, typically on Form 1040 (U.S.) or equivalent local tax forms.
Airdrops and Forks: Report the value of any airdropped or forked tokens as income at the time of receipt.

Use tax software to help automate the reporting process, or work with a tax professional who is familiar with crypto to avoid mistakes.


5. Step 5: Calculate and File Taxes for Crypto Transactions
Once your transactions are sorted and classified, calculate your overall tax liability:
Capital Gains Tax: This tax depends on whether the gains are short-term or long-term.
Income Tax: If you received crypto as income (through mining, staking, or airdrops), this will be subject to ordinary income tax rates.
Tax Deductions: If applicable, ensure to claim any deductions related to crypto activity, such as transaction fees, mining equipment costs, or staking-related expenses.

Once your calculations are complete, file your taxes with the appropriate tax authorities. Keep all records for future reference or audits.


6. Step 6: Seek Professional Help If Needed
Cryptocurrency tax laws are evolving, and the complexity of reporting transactions can be overwhelming. If you’re unsure about any part of the tax preparation process, seeking help from a professional is advisable:
Tax Accountants Specializing in Crypto: They can ensure accurate tax reporting and help you navigate regulatory requirements.
Tax Software for Crypto: Many platforms, such as Koinly or CoinTracker, can automate most of the crypto tax preparation process and integrate with exchanges and wallets.


7. Step 7: Stay Updated on New Regulations
The world of crypto taxation is rapidly evolving, with tax regulations changing as governments adapt to the growing industry:
New Tax Forms and Requirements: Keep track of any updates regarding crypto tax forms, such as IRS Form 1099-DA (U.S.) or other new reporting obligations in your jurisdiction.
Regulatory Changes: As the industry matures, governments may introduce new rules related to crypto taxation. Stay informed to remain compliant.
