Before updating 1C in 2026, an accountant should check the database and platform versions, the backup, custom modifications, data exchanges, reporting, and accounting settings affected by the release. Particular attention should be paid to switching to a different inventory valuation method (Article 248 of the Tax Code of the Republic of Kazakhstan), applications and claims for the refund of excess VAT submitted before January 1, 2026 (Article 833 of the Tax Code of the Republic of Kazakhstan), as well as the preserved terms of investment contracts and agreements concluded before that date (Articles 837, 838 of the Tax Code of the Republic of Kazakhstan).
What May Change in a New 1C Release
A 1C update may affect more than just the program’s appearance. For an accountant, changes to accounting mechanisms are more important: documents, directories, entries, statutory reports, data exchanges with external systems, and validation checks.
When reviewing a new release, attention should usually be paid to the following groups of changes:
- support for current requirements of Kazakhstan’s legislation;
- new application solution features;
- correction of identified errors;
- improved stability and performance;
- changes to document and report forms;
- enhancements to data exchanges between configurations and external services;
- changes to roles, access rights, and user settings.
The mere availability of a new release does not mean that it contains all the changes listed above. The scope of enhancements must be checked in the official version description for the specific configuration, such as accounting, payroll, or trade management.
It is important to distinguish between a platform update and a configuration update. The platform provides the technical operation of the system, while the configuration contains the applied accounting logic. Installing a new configuration release may require a compatible platform version. This requirement must be checked before work begins.
Who Is Affected by the Update
Organizations and individual entrepreneurs that maintain records in 1C need to monitor new versions. In practice, responsibility is divided among the accountant, administrator, and support specialist.
The accountant assesses whether the required forms, transactions, and checks have been added and also verifies the results using test data. The technical specialist checks compatibility, creates a backup, installs the release, and resolves potential technical errors. The manager or owner of the accounting process approves the timing of the work, especially if the database is used by several departments.
Customized databases require particular attention. If software modifications have been made to the configuration, a standard update may affect modified objects. Before installation, it is necessary to determine which modifications are in use, who maintained them, and whether they need to be adapted to the new release.
Integrations should be checked separately: data exchange between accounting and payroll, trade, or retail systems; importing bank transactions; and the operation of electronic documents, cash register equipment, and other connected solutions. Even if the main configuration starts without errors, data exchanges must be tested after the update.
What to Do Before Installing a New Release
Updating the production database without preparation is risky. A safe process begins not with installation but with reviewing the changes and creating a recovery point.
Before updating, it is recommended to:
- Determine the exact configuration name and the installed version number.
- Check which version the new release is intended for and which intermediate updates may be required.
- Read the description of changes and identify the functions affecting the company’s accounting.
- Compare the release requirements with the installed platform version.
- Check for custom modifications and connected extensions.
- Create a backup copy of the information database and make sure that it can be restored.
- If possible, perform the update on a copy of the database first.
- Coordinate the period of program unavailability with users.
The backup should be stored separately from the production database. A cloud archive may be used as an additional tool to protect against data loss caused by equipment failures, software errors, and other unforeseen circumstances. However, having an archive does not eliminate the need for a test restoration: a copy is useful only if it can actually be read.
If the database is hosted by an external provider or maintained by a specialist, determine in advance who will create the backup, who will perform the update, and who will verify the result. It is best to assign these responsibilities before work begins.
How to Check 1C After the Update
After installation, it is not enough to make sure that the program opens. The accountant needs to perform a brief acceptance check of the transactions actually used by the company.
First, check user login and access to the required sections. Then open the main directories, current-period documents, and standard reports. Make sure that documents are posted as expected and that previously entered information is displayed correctly.
A practical checklist may include:
- opening the database under different user roles;
- creating and posting a copy of a standard document;
- generating a trial balance;
- checking payroll transactions if they are maintained in this database;
- generating the applicable statutory reports;
- testing data exchanges and connected equipment;
- reviewing error messages and warnings;
- comparing key indicators before and after installation.
When checking legislative mechanisms, compare the transaction period, accounting settings, and the conditions of transitional provisions. For example, tax applications and claims for the refund of excess VAT submitted before January 1, 2026 are considered in accordance with the procedure and time limits stipulated by the Tax Code dated December 25, 2017 (Article 833 of the Tax Code of the Republic of Kazakhstan).
If an organization is implementing a priority investment project under a contract concluded before January 1, 2026, the preservation of the terms of that contract until its expiry, to the extent provided for by the article, must be taken into account when checking the settings. For contracts concluded before January 1, 2018, the guarantee of stability of tax legislation is preserved, while for contracts concluded from January 1, 2018 to January 1, 2026, the tax preferences stipulated by the contract and the guarantee of stability of tax legislation are preserved. For agreements on investment obligations with the Government of the Republic of Kazakhstan concluded before January 1, 2026, the guarantee of stability of tax legislation is preserved (Article 837 of the Tax Code of the Republic of Kazakhstan).
Under an investment agreement concluded with the authorized state body before January 1, 2026, the taxation terms and the guarantee of stability of tax legislation stipulated by the agreement are preserved until its expiry (Article 838 of the Tax Code of the Republic of Kazakhstan). Therefore, after updating such a database, the applied settings should be checked against the terms of the specific agreement.
If, at the same time as the update, the organization switches to a different inventory valuation method for accounting purposes, the positive difference arising from the switch is recognized as income (Article 248 of the Tax Code of the Republic of Kazakhstan). The accountant should separately verify the recognition of the switch and the resulting amount.
If an error is detected, the sequence of actions, the message text, and the platform and configuration versions should be recorded. This record will help the specialist reproduce the problem and distinguish a release error from the consequences of a modification or an incorrect setting.
Frequently Asked Questions
Does every new release need to be installed immediately after it is issued? — The decision depends on the scope of changes, the state of the database, and the company’s needs. First, review the version description, assess the effective date of legislative enhancements, and test the update on a copy.
Can I update 1C myself? — A trained user can update a standard database if a backup has been created in advance and compatibility has been checked. For a customized database, it is advisable to engage a specialist familiar with the modifications made.
Which is more important to update: the platform or the configuration? — These are different components. The required sequence is determined by the compatibility of the specific configuration release with the platform version.
Why do reports need to be checked after an update? — A new release may change algorithms, forms, checks, or completion procedures. Verification helps detect discrepancies before reports are submitted or the period is closed.
What should I do if an error appears after the update? — Stop bulk posting of documents, save the error text and information about the platform and configuration versions, and then provide them to the support specialist. If necessary, the production state can be restored from a previously verified backup.
