In 2026, the designation “ISNA” alone does not confirm the purpose or official address of a tax system. An accountant should first establish who sent the request and under which procedure: during a tax audit, the taxpayer is entitled to request an audit order and the official identification documents or identity cards of the officials (Article 161 of the Tax Code of the RK), while access to the premises and facilities subject to audit is granted upon presentation of the prescribed documents (Article 168 of the Tax Code of the RK).
What an “ISNA tax system” request may mean
The abbreviation “ISNA” is ambiguous without context. It may refer to an information system, an organisation’s internal module, a software product, a former service name, or an incorrectly entered search query. It cannot be regarded as a specific system of Kazakhstan’s tax authorities based solely on its name.
It is important for an accountant to establish exactly where the designation appeared:
- in a notice or another document;
- in a message from a counterparty;
- in an email containing an authorisation link;
- in the interface of accounting software;
- in an employer’s instructions;
- in internet search results;
- in an error message when submitting reports.
The context helps determine whether this concerns a government resource, a corporate system, or a third-party service. Until the owner, purpose, and full address have been established, the name “ISNA” does not confirm the resource’s official status or the sender’s authority.
How to verify ISNA without disclosing data to unauthorised persons
If a link to “ISNA tax” was received by email, messenger, or SMS, first verify the sender and the page’s full address. Do not rely solely on the logo, interface colours, or mention of a tax authority: these elements can be reproduced on an unauthorised website.
A safe sequence of actions for an accountant:
- Do not follow a shortened or suspicious link from the message.
- Do not enter a username, password, one-time code, or electronic signature details until the address has been verified.
- Find a reference to the system on the official resource of the relevant government authority.
- Compare the name, domain, purpose of the service, and prescribed login procedure.
- Ask the sender for the document number, grounds for the request, and an official response channel.
- Save the email or a screenshot if the message raises concerns.
- Before uploading files, check the scope of the requested information and the content of the document under which it is required.
An electronic signature and its password must not be given to another person. If the page asks you to download unknown software, disable browser protection, or install an unverified extension, stop and verify the request through an official channel of the relevant authority or organisation.
The authority of the employee requesting the action should also be verified separately. If the request concerns a tax audit, the taxpayer is entitled to require the tax authority officials to present an audit order, as well as official identification documents or identity cards (Article 161 of the Tax Code of the RK). The audit order must identify the persons participating in the audit: if a person is not named in it, the taxpayer is entitled to deny that person access to the premises or territory (Article 168 of the Tax Code of the RK).
What an accountant should do if ISNA is mentioned in a notice
First, determine whether the received file is an official document or an informational message. Check the addressee’s name, taxpayer identifier, date, registration details, reporting period, substance of the requirement, and specified response method. Missing information should not be filled in based on assumptions.
Then compare the notice with the documents available in the official account you use. Check not only the amount or period, but also whether the document itself is present, its status, and the specified compliance deadline. The deadline cannot be determined from the search query “ISNA tax system” alone: it must follow from the official document and the applicable provision.
If the designation “ISNA” appears only in instructions contained in an email and there is no corresponding document in the official account, contact the authority or organisation on whose behalf the message was sent through its official channel. Prepare the following for the enquiry:
- the original email without altering its content;
- the full link address;
- a screenshot;
- the document details;
- the date and time of receipt;
- a description of the action you are asked to perform;
- the error text, if one appeared.
Do not send a password, the private key of an electronic signature, or a complete set of personal data in an ordinary email. In the enquiry, describe the circumstances and provide details sufficient to identify the request without disclosing access credentials.
If the message concerns a tax audit, take into account the procedure established by the Tax Code of the RK. At the auditors’ request, the taxpayer must provide documents, accounting records, and explanations, as well as access to view data in software and an information system containing accounting and tax data (Article 161 of the Tax Code of the RK). These obligations apply specifically to a tax audit and do not confirm the authenticity of an arbitrary link or email.
How to organise an internal review of the request
It is useful for a company to establish a standard procedure for dealing with unfamiliar tax systems. Upon receiving a request bearing the designation “ISNA tax system”, the accountant records the source, establishes the owner and purpose of the resource, forwards the link to the person responsible for information security, and performs the requested action after the document and address have been verified.
The work record may state:
- who received the message;
- who sent it;
- which organisation and period it concerns;
- which document is attached;
- which address is specified for login;
- who confirmed its authenticity;
- which action was performed;
- where confirmation of submission was saved.
Such control is particularly important if the system is to be used to submit reports, sign a document, amend registration details, or upload employee data. An erroneous submission may result in the disclosure of the company’s accounting, tax, personal, and internal data.
If the purpose of ISNA cannot be established, do not enter information from the message into the accounting records or record a transaction based solely on a screenshot. First obtain a response through the official channel of the authority or organisation on whose behalf the request was sent. The obligation, deadline, and consequences should be determined from the applicable regulatory legal act and a verified document, rather than from an unexplained abbreviation.
For physical access as part of a tax audit, the audited person must admit tax authority officials after they present the audit order and their official identification documents or identity cards. If these documents are not presented or the persons who arrive are not named in the audit order, the taxpayer is entitled to deny access (Article 168 of the Tax Code of the RK). This rule allows an accountant to distinguish legally prescribed actions by auditors from a request whose origin has not been established.
Questions and Answers
What is ISNA in the tax system? — The designation “ISNA” alone does not identify a specific tax system. Identification requires the context, the resource’s full address, and the document in which this name is used.
Can I log in to ISNA using a link from an email? — Only after verifying the sender, the page’s full address, and the purpose of the resource through an official channel of the relevant authority or organisation. Until then, do not enter credentials, one-time codes, or electronic signature details.
Is there an obligation to use ISNA in 2026? — Articles 161 and 168 of the Tax Code of the RK establish the taxpayer’s rights and obligations during a tax audit, including the provision of documents and access to view accounting data, but do not establish an obligation to use a system called “ISNA”. The obligation to perform a specific action must follow from the applicable provision and an official document.
What should I do if ISNA requires an urgent report submission? — Compare the requirement with the official account and the original document, including the addressee, period, content, and deadline. If the document cannot be verified, submit an enquiry through the official channel of the authority or organisation identified by the sender.
What should be requested if the request concerns a tax audit? — The taxpayer is entitled to request an audit order and the official identification documents or identity cards of the auditors (Article 161 of the Tax Code of the RK). For access to the audited person’s premises or territory, these documents must also be presented, and the persons involved must be named in the audit order (Article 168 of the Tax Code of the RK).
How should an accountant document the verification? — Save the original message, the page’s full address, the document details, a screenshot, and the official response received. Do not save a password or the private key of an electronic signature with them.
