Accounting Policy Review and Update – Prepare Your Company for JPK CIT

JPK CIT reporting includes two structures:

• JPK_KR_PD — data from accounting books and CIT-related information
• JPK_ST_KR — fixed assets and intangible assets register, including depreciation data

JPK CIT implementation timeline – who is affected and when?

The new regulations are being introduced in stages:

• from 1 January 2025
  mandatory for tax capital groups and CIT taxpayers whose revenue for the previous year exceeded the equivalent of EUR 50 million
• from 1 January 2026
  mandatory for medium-sized enterprises (including those reporting JPK_V7)
• from 1 January 2027
  mandatory for all businesses maintaining full accounting records

What accounting policy changes does JPK CIT require?

The implementation of JPK CIT requires companies to adjust their accounting policy and accounting processes, including:

• switching to fully electronic accounting books (maintained using computer software),
• reviewing the current chart of accounts, identifying differences between accounting and tax results, and determining how these differences should be recorded (within the chart of accounts or through additional records),
• updating the chart of accounts and assigning the required tags/markers to enable correct generation of JPK files,
• updating and validating the customer and vendor database,
• expanding the fixed assets and intangible assets register, including depreciation, to ensure data completeness and compliance with the JPK_ST_KR structure,
• updating internal procedures, including accounting policies, accounting instructions, and internal control documentation, to ensure full compliance with the new reporting requirements.

Risks of failing to prepare for JPK CIT

Insufficient preparation may result in:

• inability to generate a correct JPK CIT file, which may lead to requests from the tax office or complications during a tax audit,
• penalties or sanctions for non-compliance, such as late submission or submission containing errors,
• inconsistencies in internal accounting rules and procedures, increasing the risk of operational disruption, unclear responsibilities, and difficulties during audits or inspections.
