In 2026, calculations in 1C are checked by reviewing the chain of source documents, accounting policy settings and breakdowns of the final amounts. If a tax agent reports corporate income tax withheld at the source of payment, the calculation must be submitted no later than the 15th day of the second month following the quarter in which the taxable income was paid (Article 356 of the Tax Code of the Republic of Kazakhstan).

How Cost Is Calculated in 1C

A correct calculation begins not with period-end closing but with checking the source data. Raw materials, supplies and finished goods must be entered in the directories. For each item, it is important to select the correct inventory item, unit of measurement and applicable accounting analytics.

The receipt of raw materials is then recorded in the system, specifying their quantity and cost. After the materials have been transferred to production, the production document provided by the configuration is created to record the raw materials used and the actual output of finished goods. Based on the registered data and configured settings, the system calculates the cost.

The practical sequence is as follows:

- Check the directories of raw materials and finished goods.

- Record the receipt of materials based on source documents.

- Record the use of raw materials in production.

- Register the output of finished goods.

- Perform the routine operations provided by the configuration.

- Reconcile the result against the cost and production cost reports.

If the result appears incorrect, first check the quantity of finished goods produced, the cost and quantity of raw materials written off, document dates and cost analytics. Manually correcting the result without identifying the cause is risky: when documents are reposted or the period is closed again, the system may recalculate the figures based on the registered data.

Calculation Methods and Verification of Results

Cost calculation methods in 1C depend on the specific configuration and accounting policy settings. Therefore, procedures from one database cannot automatically be transferred to another: documents serving the same purpose may contain different fields and be processed through different routine procedures.

For control purposes, it is useful to compare three groups of data:

- the cost and quantity of raw materials received;

- the quantity of materials actually transferred or written off to production;

- the quantity of finished goods produced and the costs allocated to them.

After the calculation, open the cost reports and check whether any unallocated costs remain, whether the required documents were posted in the correct sequence and whether the analytics were completed consistently. If one document specifies a department, cost item or product group that differs from those in the other related transactions, the expenses may appear in an unexpected section of the report.

For verification, it is convenient to select one batch of finished goods and trace the entire chain: receipt of a component, its transfer or write-off, the production document and the final report. This test case helps determine whether an incorrect result is related to the source data, document sequence or calculation settings.

Cost Calculation in 1C ERP, Trade Management and Manufacturing Enterprise Management

The search queries “cost calculation in 1C ERP,” “cost calculation in 1C Trade Management” and “cost calculation in 1C Manufacturing Enterprise Management” refer to different software solutions. The general principle is to consistently record the acquisition of resources, their use and the production result. However, the composition of documents, routine operations and reports is determined by the configuration, edition, enabled functionality and release.

In 1C ERP, the calculation is linked to the production module and cost allocation. In Manufacturing Enterprise Management, the procedure depends on the configured production and financial accounting. In Trade Management, check which production operations are available in the edition being used and which type of cost is calculated from the transactions registered in the database.

Before starting work, the accountant should record the exact configuration name, edition and release number. For “Accounting for Kazakhstan,” the current branch is 3.0.74.x; for “Payroll and HR Management for Kazakhstan,” it is 3.1.37.x. After updating the database, perform a test calculation on a copy or using a single controlled example and compare the result with the source documents and the previous calculation breakdown.

Payroll, Taxes and Final Settlement upon Termination

To calculate wages, individual income tax, social tax, mandatory pension contributions and social contributions, use the payroll section and the configuration’s reports on accrued taxes and contributions. The data in these reports must be checked for each employee and calculation type before payment documents are prepared.

If social tax or another figure has been calculated unexpectedly, check:

- whether the configuration and its release are up to date;

- the tax parameters in the system;

- the employee’s details and status;

- the applicable taxation procedure;

- the settings for accruals, deductions and calculation indicators;

- the registration period and document posting sequence.

After making changes, recalculate and compare the result with the detailed calculation breakdown. The reconciliation must show the calculation base and settings used by the system to derive each amount. The deadline specified in Article 356 of the Tax Code of the Republic of Kazakhstan applies only to the calculation of corporate income tax withheld at the source of payment and does not automatically apply to payroll tax and contribution reporting.

The final settlement upon termination in the Republic of Kazakhstan in 1C should begin by checking the date and grounds stated in the HR document, the employee’s accruals, and previous payments and deductions. Then create the calculation document, review the breakdown of each accrual and, after reconciliation, create the payment document. If the configuration automatically calculates related accruals, compare the result with the HR documents, timekeeping data, registered accruals, payments and deductions.

Frequently Asked Questions

Why does 1C calculate cost incorrectly? — The cause may lie in the source documents, their posting sequence or analytics: the write-off of raw materials was not recorded, the output was specified incorrectly, departments or cost items differ, or a routine operation provided by the configuration was not performed.

Can cost be calculated in the same way in 1C ERP, Trade Management and Manufacturing Enterprise Management? — No. The general logic is comparable, but the composition of documents, available functionality and calculation procedure depend on the configuration, edition, functional settings and release.

Where should the amounts of individual income tax, social tax, mandatory pension contributions and social contributions payable be obtained? — From the calculation documents and reports on accrued taxes and contributions provided in the payroll section. Before payment documents are prepared, the amounts must be reconciled against the breakdown by employee and calculation type.

What should be checked if social tax was calculated incorrectly? — Check the tax settings, employee record, applicable taxation procedure, accrual and deduction parameters, document registration period and whether the release is up to date. After making corrections, recalculate and compare the amounts with the detailed breakdown.

How can the final settlement upon termination be checked in 1C? — Reconcile the HR document, termination date, timekeeping data, accruals, payments and deductions, then review the detailed calculation breakdown before preparing the payment.
