The Ministry of Finance has taken action against those providing services in fields such as fortune-telling, astrology, and mediumship. In initial examinations, 1,034 taxpayers were found to be risky, with undeclared revenues of 1.8 billion lira identified. It was found that a person who identified themselves as an astrologer earned 15 million lira but did not pay a single penny in taxes. The Treasury and Ministry of Finance scrutinized those providing services in various fields such as fortune-telling, astrology, spiritualism, mediumship, and horoscope, but not declaring their incomes. The ministry focused on this issue due to the increase in the number of individuals providing services in various areas such as fortune-telling, astrology, spiritualism, mediumship, cupping-leech therapy, horoscope, magic, meditation, numerology, talisman, and reiki. Artificial intelligence was used to analyze the business models in the sector to investigate the income sources derived by fortune tellers, astrologers, and spiritualists. Digital traces, websites, social media interactions, online payment systems, and other data were examined to understand these incomes. It was observed that services such as astrological predictions, special spiritualist information sharing, personalized birth charts, and tarot reports were provided through face-to-face sessions, phone and messaging, as well as WhatsApp and Telegram groups. It was also noted that interactive live broadcasts on YouTube and TikTok, and posts on Facebook and Instagram were used to increase follower numbers. These individuals were found to charge per session, earn income through live broadcasts and posts on social media platforms, or offer services such as purification, meditation, and therapy during three-day or week-long retreats. Within this scope, individuals providing services in various fields such as fortune-telling, astrology, spiritualism, mediumship, cupping-leech therapy, horoscope, magic, meditation, numerology, talisman, and reiki from 2021 to 2023 were monitored based on their social media platform activities and financial data. The incomes of those who are taxpayers were compared to their declared and reported revenues. Taxpayers who operate in these areas and earn income but do not fulfill their tax obligations were identified. According to the initial results of the analysis, 1034 taxpayers were classified as “risky,” and approximately 1.8 billion lira of undeclared revenue was identified. It was found in the analysis that 295 individuals were working without being taxpayers, and the process of establishing their taxpayer status had begun. In the analysis, it was discovered that an individual earning income through fortune-telling, providing astrological predictions and spiritualist information, creating personalized birth charts and tarot reports, organizing interactive live broadcasts on social media, and earning 15 million lira through these activities, had not registered as a taxpayer and did not declare their earnings. Taxpayers are being called upon to provide explanations based on these findings. Taxpayers who do not declare their earnings or correct their previous declarations will be subjected to tax audits. Minister of Treasury and Finance Mehmet Şimşek emphasized the need to tax services like fortune-telling and astrology that individuals provide on a personal basis within the scope of self-employment activities. He stated, “Our goal is to ensure tax justice, and our fight against undeclared income will continue without exception in all earnings. Work will also be carried out for the revenues obtained in 2024. Taxpayers who comply with the call for explanation and fulfill their obligations will not face severe penalties. Taxpayers should declare their actual earnings before the declaration period ends.”
