Section 4 — Worked examples

Six fully worked classifications from a hypothetical Polish self-employed IT consultant.

Example 1 — Non-EU SaaS reverse charge (Notion)

Input line: 03.04.2026 ; NOTION LABS INC ; DEBIT ; Monthly subscription ; USD 16.00 ; PLN 64.32

Reasoning: Notion Labs Inc is US entity (Section 3.9). Import of services under Art. 28b. Report net PLN 64.32 in K_27, output VAT (23% = PLN 14.79) in K_28, input VAT PLN 14.79 in K_42 (or K_40 depending on form version). Net effect zero.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Field (output)	Field (input)	Default?	Question?	Excluded?
03.04.2026	NOTION LABS INC	-64.32	-64.32	14.79	23%	K_27/K_28	K_42	N	—	—

Example 2 — EU service, reverse charge (Google Ads)

Input line: 10.04.2026 ; GOOGLE IRELAND LIMITED ; DEBIT ; Google Ads April 2026 ; -3,800.00 ; PLN

Reasoning: Google Ireland (IE). EU service acquisition. Net PLN 3,800 in K_31, output VAT (23% = PLN 874) in K_32, input VAT PLN 874 in K_41.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Field (output)	Field (input)	Default?	Question?	Excluded?
10.04.2026	GOOGLE IRELAND LIMITED	-3,800.00	-3,800.00	874.00	23%	K_31/K_32	K_41	N	—	—

Example 3 — Restaurant service, blocked

Input line: 15.04.2026 ; RESTAURACJA POD SAMSONEM ; DEBIT ; Client dinner ; -450.00 ; PLN

Reasoning: Restaurant service (usługa gastronomiczna) — input VAT blocked under Art. 88 ust. 1 pkt 4. This is NOT catering (which would be deductible). Default: block. No input VAT.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Field	Default?	Question?	Excluded?
15.04.2026	RESTAURACJA POD SAMSONEM	-450.00	-450.00	0	—	—	Y	Q1	"Restaurant: blocked — catering (delivered) would be deductible, restaurant (on-premises) is not"

Example 4 — Domestic purchase, split payment threshold

Input line: 18.04.2026 ; DELL POLSKA ; DEBIT ; Invoice FV/2026/04/41 Laptop ; -7,995.00 ; PLN

Reasoning: Domestic purchase from Polish vendor. PLN 7,995 incl. 23% VAT. Net = PLN 6,500. VAT = PLN 1,495. Below PLN 15,000 gross threshold for mandatory split payment. Electronics (laptop) may trigger GTU_06 if client resells electronics — for purchases, no GTU required. Input VAT deductible in K_40. Check: is the supplier on the white list? Verify at wykaz podatników.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Field	Default?	Question?	Excluded?
18.04.2026	DELL POLSKA	-7,995.00	-6,500.00	-1,495.00	23%	K_40	N	—	—

Example 5 — EU B2B service sale (inbound receipt)

Input line: 22.04.2026 ; STUDIO KREBS GMBH ; CREDIT ; Invoice PL-2026-018 IT consultancy ; +16,500.00 ; PLN

Reasoning: Incoming from German company. B2B IT consulting — place of supply is Germany. Invoice at 0% with reverse charge note. Report net in K_19 (EU services supplied). GTU_12 applies (intangible/advisory services). Verify German USt-IdNr on VIES.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Field	Default?	Question?	Excluded?
22.04.2026	STUDIO KREBS GMBH	+16,500.00	+16,500.00	0	0%	K_19	Y	Q2 (HIGH)	"Verify German USt-IdNr; GTU_12 applies"

Example 6 — Vehicle, 50% restriction

Input line: 28.04.2026 ; TOYOTA LEASING POLSKA ; DEBIT ; Car lease May ; -2,200.00 ; PLN

Reasoning: Car lease payment. Passenger vehicles used for mixed purposes: 50% input VAT deduction under Art. 86a. PLN 2,200 incl. 23% VAT. Net = PLN 1,788.62. Full VAT = PLN 411.38. Deductible = 50% = PLN 205.69. Full 100% deduction requires: ewidencja przebiegu pojazdu (mileage log), VAT-26 form filed, and documented exclusive business use. Default: 50%.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Field	Default?	Question?	Excluded?
28.04.2026	TOYOTA LEASING POLSKA	-2,200.00	-1,788.62	-205.69	23% (50%)	K_40	Y	Q3	"Vehicle 50% deduction — 100% requires mileage log + VAT-26 form"

---

Section 5 — Tier 1 classification rules (compressed)

5.1 Standard rate 23% (Art. 41 ust. 1)

Default rate. Sales → K_10/K_11. Purchases → K_40.

5.2 Reduced rate 8% (Art. 41 ust. 2, Annex 3)

Food (certain categories), restaurant/catering services, passenger transport, construction/renovation of residential buildings (social housing). Sales → K_12/K_13.

5.3 Reduced rate 5% (Art. 41 ust. 2a, Annex 10)

Basic foodstuffs (bread, milk, meat, vegetables, fruit), books, periodicals, certain hygiene products. Sales → K_14/K_15.

5.4 Zero rate (Art. 41 ust. 4-11)

Exports → K_18. Intra-EU B2B goods (WDT) → K_17 (requires VIES-verified VAT number, transport proof). Intra-EU B2B services → K_19.

5.5 Exempt without credit (Art. 43)

Financial services (pkt 38-41), insurance (pkt 37), medical (pkt 18-19), education (pkt 26-29), residential rent (pkt 36), postal universal service. Excluded from JPK_V7 output boxes. If significant → R-PL-4 refuses.

5.6 Reverse charge — EU services (Art. 28b)

EU supplier invoices at 0%: net → K_31, output VAT → K_32, input VAT → K_41.

5.7 Reverse charge — EU goods (WNT, Art. 9)

Physical goods from EU: net → K_23, output VAT → K_24, input VAT → K_41.

5.8 Reverse charge — non-EU services (import usług, Art. 28b)

Services from outside EU: net → K_27, output VAT → K_28, input VAT → K_42.

5.9 Import of goods

Goods from non-EU: import VAT on customs declaration or via simplified procedure. Net → K_25, output VAT → K_26, input VAT → K_42.

5.10 Blocked input VAT (Art. 88)

• Restaurant services (usługi gastronomiczne) — fully blocked Art. 88 ust. 1 pkt 4. Catering (usługi cateringowe) IS deductible — important distinction.
• Accommodation services (usługi hotelowe) — blocked Art. 88 ust. 1 pkt 4. Exception: if resold or part of tourism package.
• Passenger vehicles: 50% default (Art. 86a); 100% requires mileage log + VAT-26 form.

Mandatory for invoices ≥ PLN 15,000 gross covering goods/services in Annex 15 (electronics, steel, fuel, construction, etc.). Payment must be split: net to supplier's regular account, VAT to supplier's VAT account. Non-compliance risks: loss of input VAT deduction, 30% sanction, joint liability.

5.12 White list verification (Art. 96b)

For payments > PLN 15,000 to VAT-registered suppliers: verify supplier's bank account is on the white list (wykaz podatników VAT). Payment to an unlisted account → input VAT deduction denied unless notified to tax office within 7 days (ZAW-NR form).

5.13 GTU codes (ewidencja section)

Sales of specific goods/services must be tagged with GTU codes (GTU_01–GTU_13) in the JPK_V7 ewidencja. For IT consultants, GTU_12 (intangible services) is the most common. GTU codes do not appear on the deklaracja section — only in ewidencja.

5.14 Sales — cross-border B2C

EU consumers above €10,000 threshold → R-EU-5 (OSS refusal). Below threshold → Polish VAT.

Known gaps

1. KSeF mandatory e-invoicing timeline is evolving — verify current mandatory dates.
2. Split payment (MPP) Annex 15 list may be updated — verify annually.

4. Vehicle 50%/100% distinction requires supporting documentation that cannot be verified from bank data.
5. GTU codes cover sales only — a future version should add detailed GTU classification guidance.
6. White list verification is flagged but cannot be performed programmatically — reviewer must verify.
