Statutory Revenue and Expense Ledger (PKPiR) administration

The Polish Tax Revenue and Expense Ledger (PKPiR) is the primary accounting instrument for sole traders and general partnerships taxed under the progressive personal income tax scale (12% & 32%) or the 19% flat-rate income tax.

  • Rigorous revenue and expense booking: Compliance with the Polish Ministry of Finance Regulation on PKPiR accounting books.
  • Expense deductibility optimization: Careful inspection of vendor receipts to legally maximize tax-deductible operational costs (KUP).
  • Formal invoice validation: Rigorous review of supplier invoices, customs documents, and banking fees.
  • Low-value assets and equipment register: Statutory registers required by Polish income tax law.

We deliver disciplined accounting records that stand up to any tax authority inspection.

Fixed assets depreciation, vehicle leasing and automotive tax deductions

Acquiring plant, machinery, hardware, or company vehicles requires accurate entry into statutory fixed asset registers and exact depreciation schedules. At NWAGNER, we structure optimal depreciation and lease deduction strategies.

  • Depreciation strategy selection: Straight-line, accelerated declining balance, de minimis instant expensing, or newly fabricated asset rules.
  • Company car tax deduction limits: Applying statutory 100% (solely business), 75% (mixed dual use), or 20% (private car use) cost thresholds.
  • Operational and financial lease deductions: Monitoring the 150,000 PLN (or 225,000 PLN for EVs) statutory ceiling on lease payments and GAP insurance.
  • Asset disposal and scrapping: Proper calculation of taxable capital gains or losses upon equipment replacement and derecognition.

We optimize your tax deductions while maintaining full compliance with statutory accounting limits.

VAT compliance, JPK_V7 filings and monthly PIT-5/5L tax advances

Monthly income tax advance calculations and comprehensive VAT ledger management are the core of our ongoing compliance service. We enforce statutory deadlines, shielding your enterprise from penalty interest or fiscal sanctions.

  • Monthly or quarterly PIT advance computations: Exact calculations for PIT-5 (progressive tax) or PIT-5L (19% flat income tax).
  • VAT input and output ledgers with JPK_V7 filing: Full input tax deduction verification and electronic monthly submissions.
  • Entrepreneur ZUS contributions and health insurance: Exact health insurance premium computation tied to taxable net profit.
  • Cross-border EU and global exports: Intra-Community trade (WDT 0% VAT, WNT), goods export, and recapitulative VAT-UE statements.

All tax returns are securely transmitted to Polish tax authorities using Qualified Electronic Signatures.

Annual physical inventory (remanent) and annual tax returns PIT-36 / PIT-36L

The culmination of the tax year under PKPiR is the physical year-end inventory valuation (remanent) and final annual income tax filing. At NWAGNER, we ensure accurate inventory delta adjustments and maximize all eligible personal tax reliefs.

  • Annual physical inventory settlement: Valuation of opening versus closing stock and correct income adjustment in the ledger.
  • Annual tax filing PIT-36 or PIT-36L: Preparation and certified electronic submission to the appropriate tax office.
  • Tax deduction and credit optimization: Child relief, thermo-modernization credits, R&D credits, and IP Box preferential regimes.
