51100: ACCOUNTING FORMS AND REPORTING FORMS IN UKRAINE FROM UKRBUSINESSCONSULT
Accounting forms 51100: how to choose the document for the required reporting period
An accounting form is linked not to the date the file was downloaded, but to the transaction and reporting period. The company first identifies the tax, fee, statistical indicator or HR event, then checks the document version and electronic form identifier.
This approach is especially important when restoring accounting records, correcting a previous declaration or preparing documents for a period whose rules were later changed.
The 51100 catalogue brings together forms used for different areas of accounting. In 2026, current filing is prepared using the official State Tax Service register and the current software version. Previously approved files remain useful for the relevant periods: they help read the company's archive, restore a calculation and prepare a correction under the rules applying on the relevant date.
The form is selected by the obligation
Work starts with an obligation record: taxpayer, tax or indicator, frequency, authority, deadline and filing basis. The name of an old file may resemble the current document, so the accountant checks the approving order, revision number and electronic identifier. For appendices, the link to the main declaration and the condition under which the appendix is completed are checked.
If reporting is prepared by an external accounting provider, the client supplies not only turnover figures but also a description of events during the period. Hiring employees, paying income to a non-resident, selling an asset, a relieved transaction or correcting an error may change the composition of the filing set. The responsible specialist records the conclusion in a working breakdown so that the manager can see how the final amount was formed.
Electronic register and software version
The State Tax Service publishes a register of electronic forms, PDF representations and XSD schemas for XML controls. The identifier shows the taxpayer category and document version. Before submission, the accountant updates the software, selects the required period, checks automatic controls and reviews the printable representation. The electronic signature belongs to an authorised person whose authority is current.
The delivery receipt confirms technical receipt, while the next receipt shows the processing result. Both documents are stored with the submitted XML and payment order. If the authority reports a discrepancy, the cause is corrected, a new file version is created and the link between the original and repeated filing is documented.
Working with prior-year periods
When restoring accounting records, a calendar is prepared by month, quarter and year. For each period it records the form in force at that time, the actual filing, receipts, payments and open issues. The form previously used helps verify the structure of the figures, while the calculation is supported by source documents, registers and the rules applicable to that period.
A correcting calculation is prepared after comparing the original declaration with the corrected data. The accountant shows the manager the change in the tax liability, the amount of additional payment or reduction and how it is reflected in current accounting. The documents are stored as one set so that a later review can reproduce the logic of the correction without oral explanations.
Company's internal catalogue
The working folder is organised by reporting type. It contains the current form, instructions, control table, completion example, details of the responsible person and a link to the official source. Previous versions are moved to subfolders for the relevant periods and retain their start and end dates of application.
Once a quarter, the accounting team checks the catalogue against the State Tax Service change feed. A change of form is immediately linked to the first filing date, software and employee. The manager receives a status register, while the team uses one agreed version. This reduces repeated work and simplifies transfer of the accounting function between specialists.
Preparing the reporting set
Before the first working meeting, the owner collects the facts that affect the result: obligations, period, source documents, accounting registers, previous submissions, payments and a current electronic signature. Documents are allocated by responsible employees and dates, while figures requiring clarification are marked for separate reconciliation. This approach helps the specialist confirm the working model more quickly and focus the consultation on decisions important for money, deadlines and contracts.
The result is prepared as a set including the confirmed version of the form, control reconciliation, ready electronic file, receipts and a structured period file. It records the official sources, source data, assumptions made, sequence of actions and confirmation of each completed stage. Where an accountant, lawyer and operations manager take part in the work, each is assigned their own part and deadline for providing information.
At the control meeting, the owner checks that each line of the report is supported by the accounting records and that the filing status is clear to both the owner and accountant. After approval, the materials are added to the corporate calendar and the company's working folders. The responsible employee updates them when participants, the contract, the object, the reporting period or a government service changes, so the adopted solution supports daily work and the further development of the business.
The final memo remains with the manager as a control tool in accordance with the company's agreed working schedule. It records completed actions, received documents, next dates and contacts of responsible persons. At the next management meeting, the team compares the actual result with the plan, records new tasks and promptly provides the specialist with information that affects the next stages of support.
