Cryptocurrency Tax Consulting

The taxation of cryptocurrencies has become one of the most complex areas of tax law. Constant regulatory changes, the wide variety of possible transactions, and the increasing level of oversight by the tax authority require specialized and ongoing planning.

Nowadays, trading in cryptocurrencies involves much more than simply reporting a capital gain. Taxpayers must properly analyze the tax implications of their transactions, comply with reporting requirements, retain sufficient documentation to substantiate the source of their funds, and be prepared to respond to potential audits or inspections.

At IN DIEM, we provide specialized tax advisory services to individuals, investors, traders, companies, and blockchain projects, helping them manage their tax obligations with legal certainty and efficient planning.

This service is part of our practice specializing in cryptocurrency taxation.

Tax Advisory Services for Individuals

Individuals who trade in cryptocurrencies may face a wide variety of tax situations. Our team provides assistance in areas such as:

  • Taxation of Cryptocurrency Sales and Exchanges.
  • Reporting of income earned through staking, lending, or airdrops.
  • Compliance with reporting obligations to the Tax Agency.
  • Wealth Tax Planning Related to Digital Assets.
  • Inheritance, Probate, and the Transfer of Cryptocurrencies.
  • Defense against tax audit and inspection proceedings.

Our goal is to tailor our tax strategy to each taxpayer’s specific circumstances, avoiding unnecessary risks and ensuring full compliance with legal obligations.

Tax Advisory Services for Businesses

Companies that engage in blockchain-related activities or incorporate cryptocurrencies into their operations have specific tax needs.

We provide consulting services in:

  • Tax obligations related to cryptoassets.
  • Asset tokenization and blockchain-based business structures.
  • Funding through token offerings.
  • Taxation of Mining Activities and Validation.
  • Accounting and Tax Treatment of Digital Assets.
  • Compliance with reporting and documentation requirements.

Each project requires a customized analysis that takes into account both tax laws and regulatory developments in the sector.

Income Tax Return and Taxation of Cryptocurrencies

Proper reporting of cryptocurrency transactions is one of the main concerns for individual investors.

Calculating capital gains and losses requires analyzing transactions carried out on centralized exchanges (CEX), decentralized exchanges (DEX), private wallets, and DeFi protocols. Additionally, transactions such as swaps, staking, rewards, airdrops, and transfers between different digital assets must be properly valued.

At IN DIEM, we conduct comprehensive analyses of taxpayers’ past financial transactions and prepare reports designed to ensure that the information is correctly included in their income tax returns.

Form 721 and Reporting Requirements

Disclosure requirements related to cryptocurrencies have increased significantly in recent years.

The Form 721 for Cryptocurrencies allows you to report certain cryptoassets held abroad when the legally established requirements are met.

The filing of this requirement must be consistent with the rest of the available tax information and must properly identify platforms, balances, and account holders.

Corporate Income Tax and Digital Assets

Companies that hold cryptocurrencies or engage in activities related to digital assets should pay special attention to their accounting and tax treatment.

The way in which cryptoassets are recorded for accounting purposes directly affects their subsequent taxation. Furthermore, tokenization transactions, the issuance of digital assets, or the use of cryptocurrencies as a means of payment may give rise to specific tax implications.

We advise domestic and international companies on the tax planning and management of these transactions.

Ongoing Crypto Tax Assistance Program

Many investors and companies engage in recurring cryptocurrency transactions throughout the year.

That is why we offer an ongoing support service that includes monitoring transactions, reviewing the tax criteria applied, preparing tax returns in advance, and adapting to changes in regulations or interpretations.

This approach helps reduce cumulative errors and maintain a well-organized and consistent tax position over time.

Tax Planning for Cryptocurrencies: How to Optimize Your Tax Liability

Tax planning involves designing a legal strategy that allows you to anticipate tax obligations, optimize your tax burden, and minimize future risks.

In the realm of cryptoassets, this planning may include reviewing asset structures, analyzing whether it is more advantageous to operate as an individual or a legal entity, offsetting tax losses, or properly documenting the source of cryptocurrency funds.

A well-designed strategy allows you to plan ahead and avoid decisions that could lead to unfavorable tax consequences.

Who needs crypto tax planning?

Tax planning is particularly recommended for:

  • Investors with significant unrealized capital gains.
  • Traders who trade frequently.
  • Users of DeFi platforms.
  • People who earn returns through staking or lending.
  • Holders of multiple wallets or accounts on international exchanges.
  • Companies engaged in activities related to the blockchain ecosystem.

In these cases, the tax complexity often warrants a preliminary, specialized analysis.

Main Taxes Applicable to Cryptocurrencies in Spain

Depending on the taxpayer’s situation, cryptocurrency transactions may affect various taxes:

  • Individual Income Tax.
  • Corporate Income Tax.
  • Wealth Tax.
  • Inheritance and Gift Tax.
  • Specific disclosure requirements related to cryptoassets.

Each of these areas has its own specific characteristics that must be examined individually.

Benefits of Proper Tax Planning

Proper planning allows you to:

  • Reduce the risks associated with regularization.
  • Avoiding errors on tax returns.
  • Legally optimize tax planning.
  • Properly prepare the supporting documentation.
  • To facilitate the defense against potential actions by the tax authorities.

Prevention is often significantly more effective than correcting problems once tax proceedings have begun.

Common Mistakes When Reporting Cryptocurrency for Tax Purposes

Some of the most common mistakes include:

  • Do not report exchanges between cryptocurrencies.
  • Exclude returns earned through staking.
  • Using incomplete information from exchanges.
  • Failure to retain sufficient documentation.
  • Confusing tax obligations with reporting obligations.

These errors are often at the root of many of the verification procedures related to cryptoassets.
