The use of cryptocurrencies in recent years is increasingly on the radar of tax authorities around the world. The growing popularity of cryptocurrencies has increased their use for transactions and investments. Tax authorities want to ensure that individuals and businesses correctly report and pay taxes on any profits or income earned.
Cryptocurrencies are treated as property for tax purposes. Consequently, this means that transactions involving cryptocurrencies are subject to capital gains tax, just like any other investment. This includes buying and selling cryptocurrencies and using them to buy goods or services.
Individuals and businesses must keep accurate records of the dates and values โโof cryptocurrency transactions to calculate their tax liability. Failure to report cryptocurrency transactions or pay taxes on profits may result in penalties or other legal consequences. Does this raise a fundamental question about (your) crypto assets?
Authorities can see your cryptocurrenciescurrency
Decentralized finance (DeFi) protocols and self-service wallets do not necessarily mean that transactions are completely hidden from tax authorities. Tax authorities can access tools and technology to track transactions on public blockchain networks. Like Ethereum, commonly used for DeFi transactions.
Many tax authorities around the world are investing in blockchain analytics tools to help them identify and track individuals who fail to report their cryptocurrency transactions. Suppose a user exchanges cryptocurrency for a fiat currency, i.e. a government-issued currency such as USD, EUR or GBP. In this case, transactions may be subject to reporting requirements under Anti-Money Laundering (AML) and Know Your Customer (KYC) laws.
This means that the cryptocurrency user is required to report transactions to the tax authorities, depending on the regulations in force in a given jurisdiction. Please note that all crypto trading activities are public. On-chain data shows activities through transactions recorded on blockchain networks.
Connecting the dots
Here, on-chain data refers to information stored on the blockchain, the public ledger of all transactions on the network. Since the blockchain is a decentralized and immutable record of all transactions, it is possible to use data matching algorithms to analyze and combine various information on the blockchain, including the ownership of both assets and digital tokens.
In some cases, owners of cryptocurrency addresses can be identified using this data in the chain. Potential breach of privacy and anonymity of these individuals. Therefore, users must be aware of the public nature of the data in the chain and take appropriate steps to adequately protect their privacy.
In general, this may include using privacy-enhancing technologies such as hashes or privacy-oriented cryptocurrencies, or taking steps to hide transaction traces associated with their addresses.
Now moving to centralized exchanges, the portal’s infamous users use it to sell, buy and store cryptocurrencies. Most centralized cryptocurrency exchanges (CEX), such as Binance, are subject to regulatory requirements. In doing so, they share customer data with tax authorities or government agencies.
In many jurisdictions, these exchanges are classified as “Designated Service Providers” (DSPs) and must comply with regulations. Including Anti-Money Laundering (AML) and Know Your Customer (KYC) regulations.
The need to comply with regulatory provisions
DSPs should collect and store customer details, including names, addresses and identification documents, under these regulations and make them available to tax authorities or government agencies upon request. Failure to comply with these requirements may result in penalties or legal action.
It is important that individuals and companies using CEX are aware of and comply with these laws to avoid potential legal or financial consequences. While decentralized exchanges (DEX) may not be subject to exactly the same regulatory requirements as CEX, they still operate in a legal and regulatory environment.
As a consequence, they may be subject to additional supervision or legal requirements. Again, rules and regulations may vary by geographic region. Currently, attention is focused on Australia, which accounts for a significant percentage (25.60%) of cryptocurrency users worldwide.
Cryptocurrency exchanges and other Designated Service Providers (DSPs) in Australia must comply with AML/CTF regulations. In doing so, we share customer information and transaction records with the Australian Taxation Office (ATO) and other relevant regulatory authorities.
Australian regulators are taking over
The Australian Taxation and Revenue Service (ATO) has implemented a new data matching program to monitor cryptocurrency transactions and ensure tax compliance. The program enabled ATO to obtain data from cryptocurrency exchanges and match them with taxpayers’ records in order to detect discrepancies.

Under Australian tax law, cryptocurrency transactions are treated as taxable events. This means that individuals and businesses must report any gains or losses from these transactions on their tax returns. The ATO warned that failure to comply with these rules could result in fines and legal action.
Essentially, the data matching program identifies taxpayers who may be under-reporting or not reporting crypto-related income. The ATO has stated that it will use the data obtained under the program to conduct compliance activities and will accordingly provide education and support to taxpayers in need of assistance in meeting their tax obligations.
Deputy Commissioner Tim Loh, regarding this tool, stated:
โWe are able to match this data to people who trade crypto assets, so be sure to include gains and losses on your tax return.โ
Individuals and businesses involved in cryptocurrency transactions should know their tax obligations and ensure they keep accurate records of their transactions. The ATO has recommended that taxpayers consult a tax professional if they need help reporting cryptocurrency-related income.
Pay taxes or fines
The implementation of the ATO data matching program is a significant step towards ensuring that cryptocurrency transactions are subject to the same tax rules as other financial transactions, and that individuals and companies are accounted for their tax liabilities.
Speaking to BeInCrypto, CPA Australia said accountants should ask clients about cryptocurrency transactions as part of their tax filing checklist.
“If you don’t ask a question you may not get an answer because many taxpayers see crypto gains and losses like betting wins and losses and don’t think about it in terms of income tax so advisers have a duty to make sure they ask clients and refund point out to them that a review is underway and they may wish to make a voluntary disclosure before the IRS knocks on their door.โ
If you have concerns about the tax implications of DeFi transactions, it is best to consult a qualified tax advisor in your jurisdiction.
Despite the efforts of the ATO, there is still a lack of understanding and awareness of the tax consequences of cryptocurrency transactions. At this point, many people may not realize they have to pay taxes on cryptocurrency gains, or may not be sure how to report their transactions to the ATO.
That is why it is so important for individuals and companies involved in cryptocurrency transactions to seek professional tax advice to ensure tax compliance.
In general, paying taxes on cryptocurrency transactions is necessary to comply with Australian tax laws. The ATO plays a key role in enforcing tax compliance, and individuals and businesses need to ensure they report their transactions correctly.
