Your personal and sole-trader data in e-US: what to compare with your own records

In e-Urząd Skarbowy (e-US), you can check your own data and the data of the business you run to verify the accuracy and currency of information held by the National Revenue Administration (KAS). This option is described in the subsection “Information about your data, your business and companies” on the official individual account page in e-Urząd Skarbowy.

Here, we focus exclusively on your own data as an individual and the sole proprietorship (JDG) you run. We do not cover searching for an entry in the REGON database, generating a Taxpayer Report, logging in or a general overview of e-US services.

Which categories of your own data does the source list?

The “Your data” section presents taxpayer data held by KAS:

• first name and surname;
• PESEL;
• NIP — if the taxpayer has one;
• residential address;
• contact details: email, telephone number and electronic address;
• personal bank account.

Do not equate your personal bank account with your tax micro-account. The official page describes the micro-account separately, as an individual tax account for payments made using it.

Which business data can you check?

For the sole proprietorship you run, the scope described in the “Your business” section includes:

• business name;
• REGON;
• PKD code for the predominant business activity.

This comparison concerns business data held by KAS, rather than instructions for finding a business in the REGON database.

An optional checklist before speaking to your accountant

The following suggestion is solely an organizational recommendation, not a legal obligation. If you would like to prepare for a conversation with your accountant, you can:

• compare your first name, surname and PESEL with your own records;
• compare your NIP, if you have one;
• compare your residential address;
• check your email, telephone number and electronic address separately;
• compare your personal bank account with your own banking records, without substituting your tax micro-account for it;
• for your sole proprietorship, compare the business name, REGON and PKD code for the predominant business activity;
• note any discrepancies you notice and questions for the conversation.

Do not treat the ability to verify information as a guarantee that it is complete or up to date. Agreement between these details alone does not establish that all tax settlements are correct. This article’s scope ends with comparing the specified categories — it does not cover procedures for correcting or updating them.
