Step-by-Step Guide to Filing Crypto Tax Returns

The rise of cryptocurrency has opened up new investment opportunities across the globe, but it has also brought a fresh set of tax obligations for investors. Many governments now treat cryptocurrency as a taxable asset, which means you need to report gains, losses, and other transactions in your annual tax return. Filing crypto tax returns can seem complex, especially for first-time investors, but with the right approach and understanding, the process becomes much more manageable.

In this guide, we will take you through each step of filing your crypto taxes, from gathering data to submitting your return, while also sharing tips to make the process smoother and compliant.

Why You Need to File Crypto Taxes

Before we dive into the steps, it’s important to understand why cryptocurrency is taxable. Most tax authorities, including the IRS in the US, treat cryptocurrency as property. This means that when you sell, trade, or even use cryptocurrency for payments, it may trigger a taxable event. Depending on your jurisdiction, activities such as staking rewards, mining income, or receiving cryptocurrency as payment for services can also be taxable.

Failing to report your crypto income can lead to penalties, interest, or even legal action. By filing your taxes properly, you ensure compliance and avoid unnecessary financial risks.

Step 1: Understand What’s Taxable

The first step in filing crypto taxes is knowing which of your activities fall under taxable events. Common taxable scenarios include:

• Selling cryptocurrency for fiat currency (e.g., selling Bitcoin for USD)

• Trading one cryptocurrency for another (e.g., exchanging Ethereum for Solana)

• Using cryptocurrency to purchase goods or services

• Earning crypto as income (from mining, staking, or freelancing)

• Receiving crypto as an airdrop or reward

Non-taxable events typically include:

• Buying cryptocurrency with fiat currency and holding it

• Transferring crypto between your own wallets

• Gifting small amounts of crypto (check local limits)

Understanding these rules helps you avoid over-reporting or missing required transactions.

Step 2: Keep Detailed Records of All Transactions

Accurate record-keeping is the backbone of proper tax filing. You should maintain a detailed log of every crypto-related transaction. This record should include:

• Date and time of the transaction

• Type of transaction (buy, sell, trade, earn)

• Amount of cryptocurrency involved

• Value in fiat currency at the time of transaction

• Transaction fees paid

• Wallet addresses or exchange account details

Keeping precise records ensures you can calculate gains and losses correctly and provide proof if the tax authority requests it.

Step 3: Calculate Your Capital Gains and Losses

Once you have your transaction data, the next step is calculating your capital gains and losses.

The basic formula is:

Capital Gain/Loss = Sale Price – Purchase Price

For example, if you bought 1 BTC for $30,000 and sold it for $40,000, your capital gain is $10,000. If you sold it for $25,000 instead, you would have a $5,000 capital loss.

There are two main types of gains:

• Short-Term Capital Gains – Assets held for less than a year; often taxed at a higher rate.

• Long-Term Capital Gains – Assets held for more than a year; usually taxed at a lower rate.

Losses can often be used to offset gains, reducing your tax liability.

Step 4: Include Crypto Income in Your Tax Return

If you have earned cryptocurrency through mining, staking, airdrops, or as payment for goods/services, this income must be reported as taxable income.

For income reporting:

• Fair Market Value (FMV) of the crypto at the time of receipt is used to determine taxable income.

• This amount is added to your ordinary income for the year.

• Later, when you sell or trade the crypto, you will also calculate capital gains or losses based on the FMV at the time you received it.

Step 5: Use Crypto Tax Software or Professional Help

Manually calculating taxes can be time-consuming, especially for active traders. Many investors now use crypto tax software that integrates with exchanges and wallets to automatically import and calculate data.

These tools help:

• Aggregate all transaction data

• Apply tax rules based on your jurisdiction

• Generate ready-to-file reports

Some advanced investment platforms, such as Valtrixio, already have built-in portfolio tracking features that make record-keeping easier. For official details and tools, you can visit valtrixio.it.

If your tax situation is complex—especially if you’ve traded across multiple exchanges or jurisdictions—consider hiring a tax professional experienced in cryptocurrency.

Step 6: Fill Out the Relevant Tax Forms

Depending on your country, different forms are used for crypto reporting. For example:

• United States:

  • Form 8949 – Lists sales and dispositions of crypto assets

  • Schedule D – Summarizes your total capital gains and losses

  • Schedule 1 or C – Reports crypto income

• United Kingdom:

  • Capital Gains Summary (SA108) for gains

  • Self-assessment forms for income

• India:

  • Report crypto gains under “Income from Other Sources” or “Capital Gains” depending on classification

Make sure to use the latest forms from your tax authority’s website.

Step 7: Double-Check Your Calculations

Before submitting your tax return, verify all entries for accuracy:

• Are all taxable events included?

• Have you accounted for transaction fees?

• Are the exchange rates correct for each transaction date?

• Have you separated short-term and long-term gains?

• Is crypto income reported correctly?

Errors can trigger audits or penalties, so a final review is crucial.

Step 8: Submit Your Tax Return on Time

Always file your return before the deadline. Late filings can lead to fines and interest charges. Most tax authorities allow electronic filing, which speeds up processing and reduces errors.

If you can’t complete your filing on time, apply for an extension, but remember that an extension to file does not necessarily mean an extension to pay owed taxes.

Step 9: Plan for Next Year’s Taxes

Once your tax return is filed, start preparing for the next tax year. Some proactive steps include:

• Keeping transaction logs updated regularly

• Setting aside a portion of profits for taxes

• Using tax-loss harvesting strategies

• Exploring crypto-friendly jurisdictions if applicable

By staying organized throughout the year, you can avoid last-minute stress during tax season.

Tips for Hassle-Free Crypto Tax Filing

• Automate Record-Keeping: Use platforms or tools that sync directly with exchanges and wallets.

• Stay Informed: Crypto tax laws can change quickly, so follow updates from your local tax authority.

• Be Transparent: Hiding crypto transactions is risky and can lead to legal trouble.

• Use Professional Advice: Even with software, complex cases may need expert guidance.
