What Should You Write in the Payment Description, and Can the Bank See It?

Have you ever wondered what exactly to write in that little "Comment" or "Payment Description" field when transferring money? Many people treat it as a formality or even as a place for jokes such as "for pizza" or "repayment of a coffee debt". However, I want to warn you: for a bank, this field is one of the most important security indicators.

Today, I'll explain how to word your payment description correctly so that your money doesn't get "stuck" during a review, and what financial monitoring specialists actually see on their screens. After reading this article, you'll know how to avoid unnecessary explanations to the tax authorities and your bank, ensuring that every transfer goes through quickly and without unnecessary stress.

Let's start with the legal aspect. A payment description is a written explanation of the purpose of your financial transaction. Depending on the type of transaction and regulatory requirements, the payment description must clearly state the nature of the transaction — what the payment is for and to whom it is being made. All information is retained for at least five years.

I believe the main purpose of this field is to identify the economic substance of a transaction. For you, this means:

1. Proof of payment — if a dispute arises with a seller or service provider, your receipt with a clear payment description will be your strongest argument.
2. Protection against tax-related issues — correct wording helps determine whether the income is subject to taxation.
3. Convenience — you can always look back through your transaction history and find out what you spent money on six months ago.

A payment instruction (which includes the payment description) serves as the basis for debiting or crediting funds to an account.

I often see people ignoring this field and leaving it blank. However, I recommend always following a few basic rules that will help keep your account "clean" in the eyes of the bank.

Here is my short checklist of what to write in the payment description:

- Be specific. 

Instead of a vague "Payment", it's better to write "Payment for consulting services", "Payment for office rent for February 2026" or "Payment for marketing services". Being specific reduces the likelihood of a manual review.

- Include the invoice or contract number. 

This is particularly important for regular or large payments. For example: "Payment according to invoice No. 123 dated 20.02.2026" or "According to contract No. 45/K dated 01.01.2026". This allows the bank to clearly identify the basis for the transfer.

- Specify VAT (if it is a business payment). 

For legal entities and sole proprietors, this is crucial. Wording such as "including 20% VAT" or "excluding VAT" immediately helps clarify tax-related matters and simplifies accounting.

- Avoid jokes and excessive abbreviations. 

The payment description is not the place for slang, emojis or internal abbreviations. What makes sense to you may be unclear to the bank.

Every transaction passes through automated filters. If the system detects something suspicious, it sends the payment for manual review. To help prevent this, I've prepared a table of appropriate and potentially risky wording.

I emphasise: if you are making a substantial transfer, your payment description must match what is stated in your supporting documents (contract or completion certificate).

This is probably the most frequently asked question. Do you need to report to the bank when sending money to your mother or sister? In fact, payment descriptions for transfers to relatives are not strictly regulated, but I recommend not leaving the field blank.

I suggest using the following phrases:

1. "Provision of non-repayable financial assistance to a relative" — this clearly indicates that the transfer is not payment for a service or business income.
2. "Gift" — monetary gifts from first-degree relatives are not subject to taxation.
3. "For household expenses" — a simple and clear description for everyday expenses.
4. "Card top-up" — if you are transferring money between your own cards at different banks.

If you're an entrepreneur, the "Payment Description" field becomes your best friend when dealing with the tax authorities. When transferring earnings from your business account to your personal card for your own needs, it is extremely important to record this correctly.

The payment description for transferring a sole proprietor's own funds should look something like this: "Transfer of the sole proprietor's (full name) own income received from business activities to their personal card for personal needs. Excluding VAT".

Why this matters:

• It demonstrates that taxes on these funds have already been paid (or will be paid according to your taxation group).
• It separates your personal money from your business assets.
• During an inspection, you won't have to prove that this transfer is not additional income subject to another 19.5% tax.

The short answer is yes — the bank can see absolutely everything. Moreover, payment descriptions are analysed not only by bank employees but also by automated systems and financial monitoring algorithms.

Let's immediately dispel a common myth: "Nobody reads payment comments." That's not true. Modern banks operate on the principle of risk analysis, where every word matters. The "Payment Description" field is scanned for keywords, unusual wording and atypical transaction patterns.

- Automated transaction scoring.

The system analyses what you spend money on, how often, how much and to whom. Based on this information, your financial profile is created. Sudden deviations from your usual behaviour (such as unusual payments or new wording) may trigger additional checks.

- Financial monitoring.

The payment description is one of the key elements in combating money laundering and the financing of illegal activities. It helps the bank decide whether to request documents or explanations.

- Data archiving.

Banks generally retain information in accordance with financial monitoring legislation (often for several years). Even if a payment was made a long time ago, the bank may revisit it during an inspection or following a request from the regulator.

- Preparation of official certificates and statements.

When you need a bank statement for a visa, residence permit, loan or property rental, the bank will prepare it using this data. If your payment descriptions are chaotic or contain unclear wording, this could work against you.

The conclusion is simple: your payment description is part of your financial reputation. A single line of text can either make your life easier or create unnecessary complications.

Over my years of working in finance, I've seen plenty of mistakes that have cost customers time and stress. I've gathered the most common ones so you can avoid them:

1. Jokes. Descriptions such as "for bribing MPs" or "for secret services" will automatically raise questions from the bank. Banks have no sense of humour when it comes to the law.
2. Leaving the field blank. In some cases (especially when making payments to corporate accounts or using IBAN details), the bank may return the payment because its purpose cannot be identified.
3. An incorrect invoice number or full name. If you write "Payment for invoice 10" but the amount doesn't match or the invoice belongs to another company, expect a call from a bank representative.

So, what should you write in the payment description? The main rule is honesty and clarity. The more transparently you describe the nature of the transaction, the less attention you will attract from regulatory authorities.

I believe filling in this field is not bureaucracy but a matter of personal financial hygiene. It protects you as a consumer, helps the bank operate more efficiently and makes your financial transactions as smooth as possible.
