Polish VAT for Foreign E-Commerce Sellers 2026: Rates, Registration, OSS & JPK_VAT Compliance

The 2026 Polish VAT Landscape at a Glance

Few EU countries have moved as aggressively toward real-time tax enforcement as Poland. Between JPK_VAT (live since 2018) and KSeF (mandatory from 2026), the Polish Ministry of Finance now receives a structured XML record of nearly every B2B invoice and every monthly VAT ledger from every registered business. Treating Polish VAT casually — the way some sellers still treat smaller EU markets — is no longer viable. The card grid below summarises the four headline VAT rates and the three special regimes (OSS / IOSS / reverse charge) that every foreign e-commerce seller must understand.

1. Polish VAT (PTU) Rates 2026 — 23%, 8%, 5%, 0% Explained

Where Polish VAT Sits in the EU Picture

Poland's 23% standard VAT rate sits in the upper-middle of the EU range. Hungary tops the table at 27%, the Nordics cluster at 24–25%, and only Luxembourg (17%) and Malta (18%) charge meaningfully less. The 23% rate has been the Polish standard since 2011, when it was raised from 22% as a "temporary" austerity measure during the eurozone crisis — every annual budget since has extended the increase, and the Ministry of Finance has confirmed it remains at 23% throughout 2026.

For e-commerce sellers, the practical importance of this rate is enormous: it applies to almost every consumer SKU shipped to Poland — electronics, fashion, footwear, cosmetics, home goods, toys, accessories, sporting goods, automotive parts. Unless your product falls inside one of the narrowly defined reduced-rate categories listed in the Annexes to Ustawa o VAT, your default working assumption must be 23%.

The 8% Reduced Rate (Annex 3)

The 8% rate is reserved for goods and services listed in Annex 3 (Załącznik nr 3) to the Ustawa o VAT. The most relevant categories for cross-border e-commerce are:

• Pharmaceuticals and medicinal products registered in the Polish Pharmaceutical Register
• Certain medical devices classified under the Medical Devices Act
• Prepared / processed foods sold ready-to-eat (the broader basic-food category sits at 5%)
• Hotel accommodation and restaurant services (relevant for hospitality marketplaces, not classic e-commerce)
• Construction and renovation services for residential housing programmes
• Certain agricultural goods, fertilisers and animal feed

The 8% rate also temporarily covered domestic energy supplies during the 2022–2023 inflation response, but those reliefs expired in 2024 and energy now sits at 23% again.

The 5% Super-Reduced Rate (Annex 10)

The 5% rate is the narrowest category — listed in Annex 10 to the Ustawa o VAT. The most commercially relevant items are:

• Basic unprocessed foods — bread, dairy, eggs, meat, vegetables, fruit (not prepared meals)
• Printed books and e-books, including academic, fiction, children's books
• Specialist children's products — including certain car seats, prams, baby formula
• Feminine hygiene products (reclassified from 8% to 5% in 2022)
• Selected unprocessed agricultural produce

Specifically for e-commerce: a Turkish or German seller shipping children's books, e-books or baby essentials into Poland can lawfully apply 5% Polish VAT, but only if the SKU matches the exact CN-code description in Annex 10. The Tax Administration treats misclassification harshly — apply 5% incorrectly and you are liable for the 18% difference plus interest plus penalty.

The 0% Rate — Intra-EU Supplies and Exports

The 0% rate (stawka zerowa) is fundamentally different from a VAT exemption. With 0% you still treat the supply as taxable — you just charge 0% — and crucially preserve the right to deduct input VAT on the costs you incurred. The 0% rate applies to:

• Intra-EU supplies (WDT — Wewnątrzwspólnotowa Dostawa Towarów) B2B where the buyer provides a valid EU VAT ID and the goods physically leave Poland
• Exports outside the EU (Poland → Switzerland, UK, US, Turkey, Norway) with customs export documentation
• International transport services related to those supplies
• Selected diplomatic / international body supplies

For a German seller shipping to a Polish B2C customer, the 0% rate generally does not apply — that's a B2C distance sale taxable in Poland at the local rate. For a Polish seller shipping to a German B2B buyer with a German VAT ID, 0% (WDT) is the standard treatment.

2026 VAT Rate Summary Table

Rate	Polish Name	Typical E-Commerce SKUs	Legal Basis
23%	Stawka podstawowa	Electronics, fashion, cosmetics, home, toys, accessories	Art. 41(1) Ustawa o VAT
8%	Stawka obniżona	Medicines, certain medical devices, prepared foods, accommodation, construction	Załącznik nr 3
5%	Stawka super-obniżona	Basic foods, books, e-books, baby essentials, feminine hygiene	Załącznik nr 10
0%	Stawka zerowa	Intra-EU B2B (WDT), exports outside EU, international transport	Art. 41(3), Art. 83

2. KAS Registration for Foreign Sellers — VAT-R and the Tax ID Process

When You Must Register for Polish VAT

For foreign e-commerce sellers, registration with KAS (the Polish National Revenue Administration) is triggered by one of three independent events — each of which alone is sufficient to make registration mandatory:

• You store stock physically in Poland — Amazon FBA Poland (Sady, Pawlikowice, Kołbaskowo), Allegro One Fulfillment warehouses, third-party 3PL or a leased Polish warehouse. The moment your goods cross the Polish border into a warehouse you control or contract for, you perform "local supplies" for Polish VAT purposes and must register on day one. No turnover threshold protects you.
• Your B2C distance sales across the EU exceed the €10,000 pan-EU threshold and you do not register for OSS — if you choose not to use the One Stop Shop, you must obtain a Polish VAT number directly.
• You make B2B supplies in Poland with local Polish establishment (a branch, a permanent presence) — although pure remote B2B between two EU VAT IDs typically falls under reverse charge and may not require Polish registration.

What KAS Actually Is

The Krajowa Administracja Skarbowa (KAS) was created in 2017 by merging the previous Polish tax administration (US — Urzędy Skarbowe), the customs service (SC — Służba Celna) and the fiscal control office into a single, unified body reporting to the Ministry of Finance. For VAT purposes, foreign sellers are typically assigned to the Drugi Urząd Skarbowy Warszawa-Śródmieście — the dedicated tax office for non-resident taxpayers — though some FBA-only sellers are routed to local offices near the warehouse they use.

The VAT-R Form and Required Documentation

The registration mechanism is the VAT-R form (Zgłoszenie rejestracyjne w zakresie podatku od towarów i usług), filed electronically through the e-Urząd Skarbowy portal. Required documentation for a foreign seller usually includes:

• VAT-R form — completed in Polish (or via a tax representative)
• Certificate of incorporation — apostilled and translated by a sworn translator
• Director ID copies — apostilled where required
• Proof of business activity in Poland — warehouse lease, FBA enrolment, marketplace contract
• NIP application (NIP-2) — Polish Tax Identification Number
• Bank account confirmation for the white-list (Biała Lista Podatników)

Processing time is typically 30–60 days for a foreign applicant, sometimes faster if a Polish tax representative submits the file. The NIP number returned takes the form NIP: 1234567890 and is the seller's universal Polish tax identifier — used for VAT, JPK_VAT, KSeF and the white list.

The White List of Taxpayers (Biała Lista)

Once registered, your bank account must be reported on the Wykaz podatników VAT (Biała Lista) — the Polish white list of VAT taxpayers, available at https://www.podatki.gov.pl/wykaz-podatnikow-vat-wyszukiwarka. Any Polish B2B buyer making a payment above PLN 15,000 to an unlisted bank account loses the right to deduct that expense for income-tax purposes — so being correctly on the white list is operationally mandatory if you sell B2B.

Tax Representative — Required for Non-EU Sellers

Non-EU sellers (Turkish, UK post-Brexit, US, Chinese) must appoint a Polish tax representative (przedstawiciel podatkowy) — a Polish-resident accounting firm or tax adviser that takes joint and several liability for the seller's Polish VAT obligations. EU sellers (Germany, France, Netherlands, etc.) are not required to appoint a representative, although many do for practical reasons.

3. OSS (One Stop Shop) — B2C Distance Selling Cross-Border

The 2021 Reform That Changed Everything

Before July 2021, every EU country had its own distance-selling threshold (€35,000 in Poland, €100,000 in Germany, etc.), and exceeding any one threshold forced a full local VAT registration. The pre-2021 regime produced a forest of 27 separate VAT numbers for any seller doing meaningful pan-EU volume. The EU VAT e-commerce package of 1 July 2021 swept all of that away and replaced it with a single pan-EU €10,000 threshold and a single optional regime — the One Stop Shop (OSS).

How OSS Works for Polish-Bound B2C Shipments

An EU-established seller (let's say a German GmbH) shipping B2C to Polish consumers:

• Stays below €10,000 / year in total pan-EU B2C distance sales → charges German VAT (19%) on Polish-bound orders
• Exceeds €10,000 / year (or opts in voluntarily) → must charge Polish VAT (23/8/5%) on Polish-bound orders
• Without OSS → needs a Polish VAT number, files JPK_VAT in Poland and a German VAT return at home, plus separate VAT numbers in every other country sold to
• With OSS → registers OSS in Germany only, files a single quarterly OSS return reporting Polish, French, Italian, etc. VAT, and the German tax office distributes the money to each Member State on the seller's behalf

The Quarterly OSS Return

The OSS return is filed quarterly, by the end of the month following the quarter (so Q1 by 30 April, Q2 by 31 July, Q3 by 31 October, Q4 by 31 January). It contains, per destination country, the taxable amount and the VAT rate applied. No invoices are submitted with the return, but you must retain transaction-level records for 10 years and produce them on request.

OSS for Non-EU Sellers

OSS is structured into three schemes: Union OSS (for EU-established sellers), Non-Union OSS (for non-EU sellers providing services to EU consumers), and Import OSS / IOSS (covered in the next section). A non-EU seller shipping goods from outside the EU directly to Polish consumers normally uses IOSS for low-value consignments and reverts to standard import VAT plus a Polish VAT number for higher-value shipments.

OSS vs. Direct Polish VAT Registration — Decision Matrix

Scenario	Recommended Path	Why
EU seller, B2C only, no Polish stock	OSS in home country	Single quarterly return, no Polish admin
EU seller, Amazon FBA Poland	Polish VAT registration + OSS	FBA stock forces Polish VAT; OSS covers other EU sales
EU seller, B2B + B2C mixed	Polish VAT registration	B2B reverse charge requires PL VAT ID
Non-EU seller, < €150 imports to PL	IOSS registration	Avoids border VAT, smoother checkout
Non-EU seller, > €150 imports	Polish VAT + tax representative	Standard import VAT + monthly JPK_VAT

4. IOSS — Import One Stop Shop for €150-and-Under Consignments

What IOSS Solves

Before 1 July 2021, the EU exempted imports below €22 from VAT — the so-called "low-value consignment relief". That gave huge non-EU sellers (notably Chinese marketplaces) a massive advantage over EU competitors and was widely seen as VAT-arbitrage. The 2021 reform abolished the €22 exemption entirely and replaced it with the Import One Stop Shop (IOSS): a single EU-wide registration for non-EU sellers importing low-value consignments (intrinsic value ≤ €150) directly to EU consumers.

How IOSS Works in Practice

A Turkish or UK or US seller shipping a €40 product to a Polish consumer:

• Without IOSS → goods stop at Polish customs (Modlin, Pruszcz Gdański), the carrier collects 23% Polish import VAT from the consumer plus a clearance fee (often €5–10), delivery is delayed, conversion suffers
• With IOSS → seller charges 23% Polish VAT at checkout, includes the IOSS number on the customs declaration, parcel clears Polish customs in minutes with no additional payment from the consumer, delivered like a domestic shipment

The seller files a monthly IOSS return in the Member State of IOSS registration, declaring the VAT collected per destination country. As with OSS, the Member State of registration distributes the VAT to Poland and the other destinations.

Where to Register for IOSS

• EU-established sellers register IOSS directly in their home country
• Non-EU sellers register IOSS via an EU intermediary — a VAT-registered EU entity that takes joint liability. The intermediary is typically a Polish accounting firm, a Dutch/Irish tax-tech provider, or a marketplace-provided intermediary (Amazon, eBay, Etsy all offer IOSS intermediary services for their merchants)
• Marketplace-facilitated sales are special: when a non-EU seller sells through a marketplace like Amazon, eBay or AliExpress, the marketplace becomes the "deemed supplier" for IOSS purposes and handles the VAT collection itself — the seller does not need its own IOSS number for those marketplace orders

The €150 Cap — Per Consignment, Not Per Item

The €150 cap is the intrinsic value of the consignment — the goods value, excluding transport, insurance and any other taxes. A single parcel of 3 items × €45 = €135 intrinsic value qualifies; a parcel of 3 items × €60 = €180 does not, and reverts to standard customs import procedures with full import VAT collection at the border. Splitting a single order into multiple parcels to stay under €150 is treated as artificial fragmentation and is challenged by customs.

5. JPK_VAT — Monthly E-Reporting (Mandatory Since 2018)

The 2018 Revolution

Long before the rest of the EU adopted SAF-T-style reporting, Poland made the JPK_VAT (Jednolity Plik Kontrolny dla VAT — Standard Audit File for Tax) mandatory in stages from 2016, reaching full universal coverage in October 2020 when the integrated JPK_V7M file replaced the separate VAT return (VAT-7) and the JPK_VAT ledger. Since then, every VAT-registered Polish business — including every registered foreign seller — files a single combined XML to KAS every month.

What's Inside JPK_V7M

The JPK_V7M file contains two sections in a single XML:

• Deklaracja (declaration part) — the equivalent of the old VAT-7: total output VAT, total input VAT, net VAT due or refundable, EU acquisitions, exports, reverse-charge transactions
• Ewidencja (ledger part) — transaction-level data: every sales invoice (with buyer NIP, net amount, VAT rate, VAT amount), every purchase invoice you claim input VAT on, and a set of special markers (GTU codes 01–13 for goods, procedure codes like SW for distance selling, MK for cash-method)

The combined effect is that KAS receives a near-real-time picture of your Polish operations — every taxable supply, every customer, every supplier — within 25 days of month end. Discrepancies between your JPK_VAT and your buyers' JPK_VAT (mismatched invoice numbers, amounts, NIPs) trigger automatic cross-check letters from KAS.

Filing Deadline and Format

• Monthly filers — file JPK_V7M by the 25th day of the following month (e.g. March file due by 25 April)
• Quarterly filers (small taxpayers) — file JPK_V7K for the declaration quarterly, but still file the ledger sections monthly
• Format — XML conforming to the official MF schema, submitted via the e-Deklaracje system, signed with a qualified electronic signature or trusted profile (Profil Zaufany)
• Currency — PLN, with foreign-currency invoices converted at the NBP (Narodowy Bank Polski) mid-rate of the day preceding the chargeable event

GTU and Procedure Codes — The Polish Twist

Poland is one of the very few EU countries that requires sellers to tag specific transaction types with code letters inside the JPK_VAT ledger. The GTU codes identify sensitive goods categories — and getting them wrong is a fast track to a KAS inspection. The most relevant for e-commerce are:

• GTU_01 — alcohol
• GTU_03 — fuel and lubricants
• GTU_05 — waste / scrap
• GTU_06 — electronics covered by the reverse-charge appendix (phones, tablets, gaming consoles, processors, certain other CN codes)
• GTU_07 — automotive parts
• GTU_08 — precious metals
• GTU_10 — buildings, structures, land
• GTU_12 — intangible services (consulting, advertising, IT)

The procedure codes (SW for distance B2C, EE for B2C electronic services, TP for related-party transactions, MK for cash accounting) add another layer of metadata.

JPK_VAT and OSS — Important Boundary

OSS-only sales (where you use the OSS regime instead of a Polish VAT number) do not appear in a Polish JPK_VAT — they appear in your home country's quarterly OSS return. But if you have a Polish VAT number, you must file JPK_VAT every month, even if your domestic Polish sales are zero in a given month — a zero JPK_VAT is mandatory.

6. Reverse Charge B2B — How It Works in Poland

The General EU B2B Mechanism

For cross-border B2B supplies between two EU VAT-registered businesses, the EU operates the reverse charge mechanism: the supplier issues an invoice at 0% VAT (treating it as an intra-EU supply, WDT), and the buyer self-accounts for VAT at its own domestic rate, simultaneously claiming the same amount as input VAT. Net cash impact on the buyer is zero, but the transaction appears in both parties' VAT records and is matched via the EU's VIES (VAT Information Exchange System).

Polish Domestic Reverse Charge

In addition to the standard intra-EU mechanism, Poland operates a domestic reverse charge for specific sensitive categories listed in Annex 15 to the Ustawa o VAT. The most commercially relevant are:

• Construction services by subcontractors to main contractors
• Certain electronics — mobile phones, gaming consoles, tablets, laptops, processors — where the single-invoice net value exceeds PLN 20,000
• Steel and metals — bars, plates, scrap
• Coal and fuels in certain quantities
• Carbon emission rights trading

The PLN 20,000 electronics threshold is critical for B2B resellers — a single B2B invoice of 50 smartphones at PLN 500 each (PLN 25,000 total) falls under domestic reverse charge and must be invoiced with 0% Polish VAT plus the annotation "odwrotne obciążenie".

Split Payment (Mechanizm Podzielonej Płatności — MPP)

Parallel to the reverse charge, Poland operates a Split Payment (MPP) mechanism mandatory for B2B invoices above PLN 15,000 in the Annex 15 sensitive categories. The buyer pays the net amount to the seller's regular bank account and the VAT amount to a dedicated VAT account linked to that bank account. Funds in the VAT account can only be used to pay VAT, social contributions and selected other taxes — they cannot be freely withdrawn. The mechanism slashes VAT carousel fraud and is one of the reasons Polish VAT compliance has tightened so dramatically since 2018.

How a Foreign Seller Practically Handles Reverse Charge

• Validate the buyer's EU VAT ID in real time via VIES before raising the invoice
• Issue at 0% with the literal annotation "odwrotne obciążenie" / "reverse charge"
• Record the WDT in JPK_VAT and in the corresponding EC Sales List (VAT-UE)
• Reconcile against VIES quarterly to catch invalid VAT IDs before KAS does

7. Amazon FBA Poland — VAT Implications for FBA Sellers

The Storage Trigger

The single most-misunderstood point in Polish VAT among foreign sellers is the FBA Poland rule. Storing inventory in Amazon's Polish fulfillment centres triggers immediate Polish VAT registration — no thresholds, no grace period. The three centres:

• POZ1 / POZ2 — Sady near Poznań (operational since 2014)
• WRO1 / WRO2 — Pawlikowice near Łódź (added 2017)
• SZZ1 — Kołbaskowo near Szczecin (added 2020, cross-border optimised)

Once a unit of stock crosses into one of these warehouses under your seller account, you are deemed to perform Polish supplies. Both the shipment of goods into the Polish warehouse from another EU country (treated as a deemed intra-EU acquisition under Polish VAT) and every subsequent sale to a Polish or other EU consumer from that warehouse generate Polish VAT obligations.

Pan-EU FBA Compounds the Problem

Amazon's Pan-EU FBA programme uses Polish fulfillment as a cheap hub for distribution to Germany, Czechia, Slovakia, Hungary, Austria, France, Italy and Spain. Polish unit costs are roughly 20–30% lower than German equivalents — but the inventory moves between Amazon warehouses without seller-initiated transactions, and each cross-border movement is a deemed intra-EU acquisition + supply in the destination country, triggering VAT obligations in every Pan-EU FBA country.

A typical Pan-EU FBA seller therefore holds seven or more EU VAT numbers (DE, FR, IT, ES, PL, CZ, sometimes more) plus OSS for non-Pan-EU sales — which is why this is one of the most heavily outsourced parts of e-commerce accounting.

The CET (Call-Off Stock) Simplification

The EU's call-off stock simplification, codified in Polish VAT in 2020, lets a seller move goods to a known buyer's warehouse without triggering immediate VAT registration in the destination country. It does not apply to Amazon FBA — FBA stock is held for unidentified future buyers and is therefore a classic case of "consignment stock" requiring full local VAT registration.

Marketplace Liability Regime (Article 14a)

From July 2021, EU rules make online marketplaces jointly and severally liable for VAT collected on B2C sales by non-EU sellers using their platforms — and Polish Ustawa o VAT transposed this into Article 14a. In practice this means Amazon and Allegro themselves collect Polish VAT on behalf of many non-EU FBA sellers, file it directly, and remit the seller's net proceeds excluding VAT. The seller's own Polish VAT obligation reduces to consignment-stock movements and any B2B sales not covered by the marketplace deemed-supplier rule.

8. KSeF — Mandatory National E-Invoice System from February 2026

What KSeF Is

KSeF (Krajowy System e-Faktur — National e-Invoice System) is the Ministry of Finance's central e-invoicing platform, which from 2026 becomes the only valid channel for issuing Polish B2B and B2G invoices. Conceptually it sits between Italy's SDI (the EU pioneer, mandatory since 2019) and France's Chorus Pro / PDP model: every invoice is issued in a structured XML format (FA(2) schema), submitted directly to the KSeF API, and assigned a unique 10-character KSeF identifier that effectively replaces the seller's sequential invoice number for legal purposes.

The 2026 Rollout Calendar

The Ministry of Finance's confirmed timeline:

• February 2026 — KSeF becomes mandatory for large taxpayers (turnover above PLN 200M / approx. €45M)
• April 2026 — KSeF becomes mandatory for all other VAT-registered businesses, including foreign sellers with a Polish NIP
• Throughout 2026 — B2C invoices remain optional in KSeF; if issued via KSeF they are valid, if issued on paper or PDF they are still valid
• From 2027 — gradual extension to B2C (under review)

What Foreign Sellers Must Do

A foreign seller with a Polish VAT number (whether EU or non-EU established) falls inside KSeF scope. Practical steps:

• Obtain a KSeF API certificate from the Ministry of Finance e-portal — this is the cryptographic credential used to authenticate API calls
• Configure your invoicing software (or use Zunapro's KSeF module) to produce FA(2) XML — the schema has 70+ fields, including buyer NIP, supplier NIP, GTU codes, payment terms, due dates
• Submit each invoice to the KSeF API before delivering it to the buyer; the API returns the 10-character KSeF identifier within seconds
• Store the KSeF identifier with the original order and surface it to the buyer for KSeF-side download
• Apply Q-marketplace mapping — Allegro, Amazon and Empik orders to Polish B2B buyers all flow through KSeF, requiring marketplace-to-KSeF data piping

Why KSeF Matters Operationally

• VAT refunds accelerate — KSeF-issued invoices qualify for an accelerated 40-day VAT refund (vs the standard 60 days)
• The 10-character identifier replaces the invoice number for legal purposes — no more "lost invoice number" disputes
• KAS receives every invoice in real time — JPK_VAT becomes partly redundant because the underlying data is already in the Ministry's database
• Cross-checking is automated — any KSeF invoice not appearing in the buyer's own KSeF input log triggers an immediate cross-check letter

9. Penalties — What Happens If You Get It Wrong

The Three Layers of Polish VAT Enforcement

Polish VAT enforcement operates on three legal tracks, often applied cumulatively for serious cases:

• Tax-administrative sanctions under the Ustawa o VAT — automatic uplift to the VAT due
• Fiscal-penal liability under the Kodeks karny skarbowy (Fiscal Penal Code) — fines expressed in daily rates, up to 720× daily rate, plus potential imprisonment for the most serious offences
• Interest on tax arrears — calculated at the National Bank of Poland reference rate plus 4 percentage points (standard) or up to 150% of that base rate (penalty interest)

Specific Headline Penalties

• Failure to register for VAT when required — retroactive liability for all uncollected VAT, plus 30% sanction on under-declared VAT, plus interest
• Late JPK_V7M filing — up to PLN 500 per missing record in the ledger, plus PLN 720 fixed penalty for the late filing itself, plus daily-rate fiscal-penal exposure
• JPK_VAT errors — KAS can demand correction within 14 days; failure to correct triggers PLN 500 per uncorrected line
• Failure to issue a KSeF invoice (from February 2026) — up to 100% of the invoice VAT amount as administrative penalty, plus fiscal-penal exposure
• VAT carousel / fictitious invoices — criminal exposure: up to 25 years imprisonment for organised VAT fraud, plus 720× daily-rate fines, plus full restitution
• White-list violation (B2B payment above PLN 15,000 to unlisted account) — loss of expense deduction for the buyer; the seller can be jointly liable

The "Belka Tax" and Other Adjacent Hits

Foreign sellers sometimes confuse VAT penalties with the 19% capital-gains tax (Belka tax) or CIT on Polish-source income. They are separate regimes — but a finding of unregistered VAT activity in Poland almost always triggers a parallel CIT investigation by the same KAS office, multiplying the eventual liability.

10. Practical 2026 Compliance Checklist for Foreign Sellers

Step 1 — Diagnose Your VAT Trigger

• Do you store stock in Poland (FBA / 3PL / own warehouse)? → Polish VAT registration required immediately
• Are your pan-EU B2C distance sales above €10,000 / year? → OSS registration in home country (EU sellers) or IOSS via intermediary (non-EU, ≤ €150 consignments)
• Do you make B2B supplies into Poland? → Confirm whether reverse charge applies (Annex 15) or you need a Polish VAT number
• Do you make distance B2C sales below €10,000? → Charge home-country VAT; no Polish admin required (yet)

Step 2 — Register for the Right VAT Regimes

• EU seller, FBA Poland → VAT-R + NIP-2 → Polish VAT number + OSS for non-PL sales
• EU seller, OSS only → OSS registration in home Member State, quarterly returns
• Non-EU seller, marketplace-only → marketplace acts as deemed supplier for B2C; verify Article 14a treatment
• Non-EU seller, direct shipments ≤ €150 → IOSS via EU intermediary (often a Polish accountant)
• Non-EU seller, direct shipments > €150 → Polish VAT registration + tax representative + monthly JPK_V7M

Step 3 — Wire Up the Reporting Stack

• Polish NIP on the Biała Lista (white list of taxpayers) with the correct bank account
• Monthly JPK_V7M XML, filed via e-Deklaracje by the 25th of each month
• Quarterly OSS return in home Member State
• Quarterly VAT-UE (EC Sales List) for intra-EU B2B supplies
• Monthly IOSS return in Member State of IOSS registration (where applicable)

Step 4 — Activate KSeF Before February / April 2026

• Obtain a KSeF API certificate from the Ministry of Finance
• Implement the FA(2) XML schema in your invoicing pipeline
• Pipe each marketplace B2B order through KSeF and store the returned 10-character identifier
• Confirm white-list and KSeF cross-references match every invoice

Step 5 — Run Quarterly Compliance Checks

• VIES validation of all B2B customer VAT IDs (quarterly)
• Reconciliation of marketplace order data against JPK_V7M and KSeF identifiers
• White-list spot check against Polish suppliers above PLN 15,000
• GTU code review for any new SKUs in sensitive categories (electronics, automotive, fuels)
• OSS / IOSS threshold monitoring — confirm you are still inside the regime you registered for

Step 6 — Centralise Everything in Zunapro

1. Sign in to Zunapro and open the Poland accounting module
2. Connect your marketplaces — Allegro, Amazon.pl, Empik, Ceneo, Morele.net, Erli
3. Provide your Polish NIP, OSS / IOSS identifiers, and KSeF certificate
4. Map SKUs to VAT rates — Zunapro suggests 23 / 8 / 5 / 0% based on CN codes and Załącznik references
5. Enable auto-filing — JPK_V7M monthly, OSS quarterly, KSeF on every B2B invoice
