We deliver specialized forensic accounting for reconstructing delinquent general ledgers and past tax records from previous financial years.

We compile complete packages of retroactive tax corrections for VAT, JPK_V7, CIT-8, PIT-36L, and ZUS declarations backed by formal legal justifications. We draft overdue statutory XML financial statements for the e-KRS court repository, reconciling balances and protecting boards from fiscal penalties.

Diagnostic audit and forensic inventory of delinquent accounting records

The process of reconstructing or cleaning up delinquent accounting ledgers begins with an exhaustive diagnostic forensic audit. We pinpoint which fiscal periods were closed correctly, map missing documentation gaps, and assess exposure risks for the board of directors.

  • Database and source documentation review: In-depth audit of ledger entries, VAT registers, asset books, and historical payroll.
  • Statutory balance reconciliations: Retrieving and verifying official tax and social security clearance statements directly from US and ZUS.
  • Missing document mapping: Assembling a structured shortfall audit list (missing vendor invoices, bank feeds, contracts).
  • Remedial blueprint and schedule: Establishing step-by-step correction milestones, priority tax filings, and fiscal impact models.

We provide executive leadership with unvarnished clarity regarding historical risks before initiating corrective journal entries.

Document recovery, journal re-posting and full ledger reconstruction

Following the diagnostic audit, we proceed with the systematic digital and physical reconstruction of delinquent accounting records. We post journal entries chronologically, ensuring exact attribution to statutory reporting periods.

  • Duplicate document and bank feed retrieval: Assisting in obtaining historical banking archives and vendor invoice duplicates.
  • Comprehensive journal re-posting: Entering transactions into Symfonia ERP under strict Polish Accounting Act protocols.
  • Reconstruction of VAT registers and JPK files: Re-establishing statutory tax point dates and input VAT deduction validity.
  • Fixed assets and depreciation rebuilding: Re-calculating historical cost baselines, depreciation rates, and cumulative allowances.

We restore total financial data integrity and balance sheet coherence for your business.

Filing retroactive VAT, CIT, PIT and ZUS corrections and balance reconciliation

Reconstructing accounting books almost invariably uncovers variances between true transactional reality and past tax filings. We generate comprehensive packages of retroactive tax corrections accompanied by formal statements explaining the grounds for amendment.

  • Retroactive JPK_V7 corrections: Rectifying input/output VAT balances and clearing erroneous transaction codes (GTU) and procedure flags.
  • Annual CIT-8, PIT-36/36L, and PIT-28 corrections: Re-computing taxable profit baselines and settling overdue balances or refund claims.
  • ZUS social security correction filings: Correcting individual employee contribution bases and amending statutory personal reports.
  • Tax overpayment allocation & installment petitions: Drafting formal motions for overpayment offsets or debt installment plans with authorities.

We execute corrections systematically to minimize fiscal penalty exposures and interest penalties.

Annual statutory close, corrected accounts and implementing bulletproof standards

The final milestone of a reconstruction project is compiling past statutory financial statements, submitting them to the Polish Court Register (e-KRS), and embedding robust internal accounting controls to ensure historical failures never reoccur.

  • Overdue XML financial statements: Drafting statutory Balance Sheets, Profit and Loss Accounts, and Notes for past financial years.
  • Filing with the e-KRS repository: Assisting the management board in clearing past court compliance notices and warnings.
  • Paperless workflow rollout: Replacing physical document binders with a secure cloud portal and automated KSeF invoicing.
  • Ongoing accounting transition: Seamless transition to ongoing monthly bookkeeping under certified senior CPA supervision.

We resolve past compliance distress and place your company on solid, audit-proof operational ground.

Loss, destruction or missing accounting documents is one of the most common “dark hours” for a business owner. Flood, disk failure, tax audit, a previous accountant’s error or documents that “went missing” – there are many causes. You cannot just “put something in Excel”. Books must be reconstructed legally under the Accounting Act and Tax Ordinance.
