Crypto Audits in 2025 - the Polish Tax Authorities Are Scrutinising Poles' Accounts

The tax authorities are on the hunt - mass audits of cryptocurrency accounts

Polish tax offices (urzędy skarbowe) have launched an unprecedented wave of audits targeting holders of cryptocurrencies. According to media reports, including the Wyborcza.biz portal, law firms are increasingly being contacted by worried clients who have received requests for explanations concerning their digital assets. The scale of the tax authorities' activity points to a systematic, coordinated approach rather than isolated, random audits.

The main focus of tax analysts is currently the 2021 tax year - a period of particular boom on the cryptocurrency market, when many investors made significant profits. Importantly, officials are not carrying out a comprehensive review of the taxpayer's entire assets. Their activity is focused solely on settlements related to virtual currencies, which shows a precisely defined direction for the audits.

Lawyers specialising in cryptocurrency law point out that, in unofficial conversations, officials admit to receiving top-down guidelines requiring them to check a set number of "crypto taxpayers". This means the audit machine operates on the basis of set quotas, which the offices must account for in their reports.

The CRS Directive and the tax authorities' new tools for tracking cryptocurrencies

The key instrument that has enabled the tax authorities to act on such a broad scale is the CRS (Common Reporting Standard) Directive. This is an international standard for the automatic exchange of tax information between OECD countries, which for years remained largely "dormant" in Poland. Now, however, tax offices have begun actively and extensively collecting data on the foreign accounts of Polish taxpayers.

The way CRS works is simple but extremely effective - foreign financial institutions, including banks and cryptocurrency exchanges, automatically pass on information about accounts held for Polish tax residents. The tax authorities therefore receive a complete picture of where Poles keep their funds abroad, including accounts linked to cryptocurrency trading platforms.

In addition, the tax authorities have gained access to new, advanced analytical tools dedicated to auditing so-called crypto accounts. These make it possible to identify transactions, trace financial flows and select taxpayers who may have failed to meet their tax obligations. In practice, this means that concealing cryptocurrency profits has become much harder than it was just a few years ago.

Who is in the firing line? Three main selection criteria

The Ministry of Finance officially confirms that audits in the area of cryptocurrencies are under way, although it does not disclose their scale - it provides neither the number of accounts examined nor the number of requests sent. Based on the available information, however, we can point to three main factors that determine whether a given taxpayer ends up in the tax authorities' sights:

  1. A connection with the Zondacrypto exchange - as one of the most popular cryptocurrency exchanges available to Poles, this platform has become an object of particular interest to officials. Data on users' transactions and balances may be obtained through information exchange mechanisms.
  2. Risk analysis algorithms - the Ministry of Finance states that audits are based on the results of advanced risk analysis, which determines the likelihood of irregularities. The algorithms may analyse discrepancies between declared income and activity on bank accounts and exchanges.
  3. Tip-offs - officials admit that reports from third parties remain an extremely effective way of selecting taxpayers. Even a private conversation about cryptocurrency investments with friends can end in a tip-off to the tax office.

The last point is particularly worrying. It means that the risk of an audit stems not only from algorithms and system data, but also from the human factor - envy, spite or simply the "civic vigilance" of the people around us.

Consequences - a 75% additional tax assessment and criminal liability

The consequences of having undeclared cryptocurrency profits discovered can be very severe for a taxpayer. Polish law provides for harsh sanctions in this area, the scale of which depends on the nature and circumstances of the breach.

Where a taxpayer cannot prove a legal source of income, the tax authorities may apply a so-called additional tax assessment. This means undisclosed income is taxed at a penalty rate of as much as 75 per cent. With amounts of the kind mentioned in the cases cited - running into millions of zloty - the financial consequences can be nothing short of catastrophic for a household budget.

The situation becomes even more serious when the tax authorities find deliberate action to the detriment of the State Treasury. If a taxpayer tried to conceal income, for example by using a false identity or otherwise breaking the law, fiscal criminal law provisions and even provisions of the Criminal Code come into play. These may result not only in heavy fines but also in imprisonment.

It is worth stressing that the burden of proof in such proceedings rests largely on the taxpayer. It is the taxpayer who must show where the funds held in their accounts came from - both domestic and foreign.

How to prepare for a cryptocurrency audit

In the face of intensifying audits, proper preparation is crucial. Whether a taxpayer has already received a request or wants to protect themselves for the future, it is worth taking concrete steps:

Remember that responding to a tax office request is mandatory. Ignoring correspondence from the tax authorities will not solve the problem, but may significantly worsen the taxpayer's situation and lead to an escalation of audit activity.
