Small amounts, big problems - even minor transfers attract the tax authorities' attention

Although it might seem that only large transfers attract the attention of the National Revenue Administration (KAS), a series of small transfers can also be the start of serious consequences for the sender or the recipient. Small amounts can add up to a sum that raises suspicion - and then an inspection may not be far off.

What exactly do the tax authorities check?

• Banks must report suspicious transactions to the General Inspector of Financial Information (GIIF) - including those that seem small but are repeated or of unclear nature.
• Attention is drawn to: transfers of similar amounts sent regularly, especially to the same person; transfers without a specific title ("transfer", "for tomorrow", "for a service"); and frequent micro-payments that add up to a significant sum.
• Example: several months of PLN 200-300 paid into one person's account, with no descriptions and no stated source - this may be interpreted as an attempt to conceal income or as a gift.
• Banks and KAS can block an account for up to 72 hours, and in extreme cases for up to 3 months, if there is a suspicion of money laundering or concealment of income.

Why are micro-transfers a problem?

1. Accumulation of amounts – Although a single transaction may seem insignificant, a set of many such transactions can add up to a sum that requires an explanation.
2. Lack of documentation – If incoming payments are not supported by a contract, an invoice or a stated purpose of payment, they may raise suspicion.
3. Inconsistency with your return – If someone receives income that they do not report in their tax return, this may be a warning signal for the tax authorities.
4. Transfer titles – Vague titles ("for tomorrow", "for something") do not make it easier to demonstrate the purpose of the transaction - they may be interpreted as a concealed operation.

How to protect yourself? Practical tips

• Always try to describe the transfer precisely: state what you are paying for or what you are receiving - e.g. "reimbursement of building material costs", "gift from mother for flat renovation", etc.
• If you regularly receive or send funds - keep an archive of documentation: contracts, invoices, confirmations of receipt or transfer, internal notes.
• For gifts between unrelated persons - check the gift tax exemption limits and whether the gift must be reported to the Polish Tax Office (urząd skarbowy).
• Avoid terms such as "transfer" or "for tomorrow" as a title - it is better to be specific and consistent with the real purpose.
• If you run a business or have income from various sources - make sure the funds received in your account are consistent with what you declare in your PIT or CIT return.

Who is this article especially important for?

• Individuals who receive regular transfers from friends, family or contractors - and do not realise that they may exceed gift thresholds or be asked for explanations.
• Entrepreneurs and business owners - especially if part of their income may be informal or if they rely on many small payments.
• Partners and shareholders of companies who receive royalties, dividends or other income - every transaction may be analysed by the tax authorities.

Summary

Do not be misled by a seemingly small amount - it is rather the pattern and the transaction profile that decide whether you will be asked for explanations. Transparency, documentation and clarity are your best protection against an inspection.
