No more anonymity in the network, at least for the Polish tax. The National taxation Administration (KAS) in 2025 enters a full fresh level of control, utilizing advanced technologies to analyse our digital footprints. Your public photos of luxury holidays, a fresh car or an costly watch can be automatically compiled with data from your yearly PIT taxation return. If the algorithm detects a gross disparity between declared incomes and the lifestyle presented, you may anticipate a call to the office. It's not discipline fiction, it's a fresh reality that aims to seal the taxation strategy and fight the grey zone. Experts inform that for many Poles, especially those gaining income from undeclared activity, hard times are coming. The strategy is to be preventive, but its effectiveness in detecting irregularities may surprise even the most cautious.
How does the fresh KAS work? It's not magic, it's a data analyst.
The fresh tool of the National taxation Administration is based on advanced large Data analysis and device learning algorithms. This is not an authoritative manually browsing your Instagram or Facebook profile. It's a powerful strategy that actually aggregates and crosses data from many seemingly unrelated sources. The main nonsubjective is to identify alleged "undisclosed sources of revenue". The strategy scans publically available information on the Internet, including social networking sites, announced websites (e.g. OLX, Otomoto) and net forums.
The process is as follows:
- Data collection: Algorithms search the network for information related to your individual data (name, surname, city). They analyse photos, posts and ads.
- Behavioral analysis: The strategy evaluates lifestyle – frequency and directions of travel, brands of purchased products, vehicles and even the kind of restaurants visited.
- Crossing with databases: The collected information is compared with authoritative records specified as CEPiK base (vehicles), land registry (real estate) and, most importantly, your PIT statement and data from the STIR strategy (the IT strategy of the clearing house), which monitors the flows in bank accounts.
- Alert generation: If the strategy detects a crucial discrepancy – for example, pictures from a monthly journey to Asia at declared national minimum income – it generates an alert that goes to the KAS analyst for further verification.
It is automation and scale of action that represent the revolutionary nature of this solution. The strategy does not get tired and is able to analyse millions of profiles in a short time, typing those that request detailed control.
What precisely does the taxation check? Luxury holidays are just the beginning
Although the pictures from exotic beaches are the most pictorial example, the interests of the taxation are much wider. Algorithms were programmed to search for circumstantial signals indicating possible taxation irregularities. The mark was not only consumer spending, but above all evidence of unregistered business. Officials know very well that social media has become a powerful marketing tool for the grey zone.
This is what the strategy pays peculiar attention to in 2025:
- Unregistered services: Announcements on repair services, cosmetics, tutoring or wedding photography, published on local Facebook groups without registered company.
- Sales and rental: Regular sale of goods (e.g. clothes, handicrafts) by social media or rent of “black” housing announced on portals.
- Expensive shopping: To brag about a fresh luxury car, an costly watch, or a bag of a well-known brand whose value importantly exceeds the authoritative yearly income.
- Financing sources: The analysis of whether the life - kind presented could have been financed from legal sources. If not, the office may ask about the origin of the funds, specified as donations or inheritances, which are besides subject to taxation.
It is crucial to realize that the taxation does not question the specified fact of having luxury goods. The problem is that it is not possible to prove that they were acquired for the money from which the taxation was paid.
Who's on target? These groups should be on guard.
The fresh analytical tools of the KAS are not aimed at all citizen. The strategy is designed to first choice people and professional groups, where the hazard of a grey region is statistically highest. If you are 1 of them, you should take peculiar care to guarantee the transparency of your finances. In 2025, the list of “suspects” are headed by influencers, freelancers and manufacture representatives, where cash payments are common.
Particular attention will be paid to the following groups:
- Influencers and net creators: For promoting products in the barter (which is besides revenue) or receiving payments without issuing invoices.
- Construction and repair specialists: For the provision of services without registration of the activity and the acceptance of the payment “on the hand”.
- Beauty industry: Cosmetics, hairdressers, make-up artists frequently do business at home without appropriate registration.
- Trainers and trainers: Their announcements are easy to find online, and revenues are seldom full reported.
- Renters: Especially short-term rental, which frequently bypasses the taxation system.
For these people, public online activity, which has been a tool to get customers so far, can become evidence in taxation proceedings. The Fiscus assumes that if individual publically advertises their services, they conduct a gainful activity which must be reflected in documents.
How can we defend ourselves and avoid problems? The key is transparency
In the face of specified advanced control tools, the ‘something’ strategy is no longer effective. The best defence is full transparency and the regulation of your taxation affairs before the office becomes interested. It is not about giving up social media, but about ensuring consistency between digital image and financial reality.
Here are any applicable steps to take:
- Do a gross review: Make certain that all sources of gross from the last year (and erstwhile years, remembering the five-year limitation period) have been correctly reported in PIT statements.
- Document revenue: If you receive donations from a household that translates larger expenses, make certain they have been reported to the taxation office on appropriate forms (SD-Z2).
- Register: If you regularly supply services or sale goods, consider registering your business. Different forms of taxation are available, including undeclared activities up to a certain income threshold.
- Be careful online: Think twice before you publically brag about your costly acquisition if you do not have the authoritative income to cover it. Consider changing your profile privacy settings to more restrictive.
The era of digital transformation has reached the taxation administration for good. In 2025 our digital footprint was an open book, from which the fiscal can read more and more efficiently. Taking care of financial order and the compatibility of taxation returns with reality is not only an work but the best insurance policy against the costly consequences of taxation control.
