The Polish registered lump-sum tax (Ryczałt) offers highly competitive tax rates, yet its main exposure lies in misclassifying invoice service scopes under PKWiU codes. We inspect your service descriptions and invoicing categories to ensure 100% fiscal compliance.
We review your invoices continuously, shielding your business from retroactive reclassification audits by tax chambers.
Many sole proprietors under the lump-sum scheme also operate as registered VAT taxpayers. At NWAGNER, we maintain both your statutory Revenue Ledger and full VAT purchase and sales registers.
We deliver synchronized management of your flat revenue tax and full Value Added Tax compliance.
Under Polish lump-sum taxation, ZUS health insurance contributions are tiered into three distinct revenue brackets (under 60k PLN, 60k–300k PLN, and over 300k PLN). We track your cumulative revenues month-by-month to prevent unexpected year-end settlement surcharges.
You receive exact monthly payment summaries with bank accounts and statutory deadlines.
Partnering with NWAGNER is entirely paperless and tailored for tech contractors, consultants, and modern digital businesses. Your subscription includes complimentary access to our cloud invoicing tool fully integrated with KSeF.
You save valuable hours each month while enjoying absolute peace of mind regarding your taxes.
