Poland Tax Intelligence – Government Resets Tax Reform, 22% CIT for Large Firms, Windfall Fuel Tax, Estonian CIT Crackdown

Executive Summary

Poland’s tax landscape is dominated by a dramatic legislative reset: the government has withdrawn its comprehensive tax reform bill and restarted drafting from scratch, even as parallel Sejm/Senate proceedings advance a 22% CIT rate for large groups (revenue > EUR 20M), PIT threshold increases, and Pillar Two implementation. The Windfall Profits Tax on fuel took effect November 1. Estonian CIT faces intensified scrutiny on related-party loans and rents. The EU ViDA package is being transposed for e-commerce VAT, a new EU customs handling fee applies to low-value parcels, and the Polish Investment Zone regime has been overhauled. KSeF penalty moratorium extended to end-2027. OECD transfer pricing guidance for intra-group services is being overhauled for AI. Enforcement actions target VAT carousel fraud, illicit tobacco, and illegal gambling.

Important Updates

Government Resets Tax Reform Legislation; 22% CIT for Large Groups and PIT Threshold Hikes Advance

The Ministry of Finance announced a complete restart of the tax reform package on November 3, citing an “unprecedented situation” from conflicting Sejm/Senate amendments. All prior legislative progress is nullified; a new cohesive bill targeting constitutional compliance is expected in Q1 2027 for 2028 effect. Simultaneously, a fast-tracked bill passed both chambers on November 5-6 introducing a 22% CIT rate for entities with revenue exceeding EUR 20 million (approx. 1,200 taxpayers), raising the first PIT threshold from PLN 120,000 to PLN 150,000 (tax-free allowance to PLN 30,000), lowering the flat-rate (ryczałt) revenue limit from EUR 2M to EUR 1.5M, and closing Estonian CIT to new entrants from 2027. The bill awaits presidential signature; a veto would delay implementation to 2028. Constitutional doubts persist over omnibus structure and accelerated procedure. Businesses should model 22% CIT impact on 2027 provisioning and monitor legislative tracker.

Windfall Profits Tax on Fuel Sector Takes Effect November 2026

Effective November 1, 2026, the Act on Windfall Profits Tax in the Fuel Sector imposes a temporary 33% tax on extraordinary profits of refineries, importers, and wholesalers through December 2027. The tax base is the positive difference between the average monthly margin per fuel type (gasoline, diesel, LPG) and a reference margin (2019-2021 average plus 20%). Monthly returns due by the 25th of the following month via e-Tax Office; first return due December 25 for November 2026. Exemptions apply for entities with turnover below PLN 50M and those investing ≥15% of revenue in renewables. Expected annual revenue: PLN 5-8B for energy price subsidies. Affected groups (PKN Orlen, Lotos, international traders) must maintain detailed margin records for five years.

Estonian CIT: Loans to Related Parties Treated as Hidden Profit Distribution

Tax authorities consistently classify financing provided to shareholders or related entities by Estonian CIT companies as hidden profit distribution (ukryty zysk), subject to 19% CIT in the month funds are made available — regardless of market-rate terms or repayment schedules. The mere related-party status (per Art. 11a CIT Act) triggers the presumption; the burden shifts to the taxpayer to prove genuine business purpose. The 2024 safe harbor (maturity ≤5 years, rate ≥WIBOR 1M + margin) does not apply if the borrower holds ≥25% shares. Tax due by the 20th of the following month; late payment incurs 14.5% interest. Companies must document business rationale, obtain corporate resolutions, set arm’s-length rates per OECD guidelines, and prepare transfer pricing documentation (TPR) for transactions exceeding PLN 10M (PLN 2M for financial). This affects all Estonian CIT groups with intra-group financing or cash-pooling structures.

Poland Implements EU ViDA Package for E-Commerce VAT; Deemed Supplier Rules Extended

The Council of Ministers approved draft bill UC-461 on October 28, transposing the first pillar of the EU VAT in the Digital Age (ViDA) package, effective January 1, 2027. Key changes: EU-wide €10,000 OSS threshold calculated on calendar-year aggregation of all B2C services and distance sales; taxable event moment aligned with VAT Directive Art. 14; website address declaration in VAT-R abolished; digital platform operators (marketplaces) gain deemed supplier liability for VAT on B2C supplies, extended to short-term accommodation rentals and passenger transport. Platform operators must register for OSS and implement deemed-supplier invoicing by 2027. Penalties up to PLN 20,000 per incorrect return and potential input VAT denial. Taxpayers should gap-analyze OSS/IOSS processes and engage ERP vendors.

New EU Customs Handling Fee for Low-Value Distance Sales Parcels

Effective October 30, 2026, a new EU handling fee (opłata manipulacyjna) applies to each customs declaration for low-value parcels (≤EUR 150) shipped via distance selling into the EU. In Poland, the fee is PLN 20 per declaration, payable by the declarant (postal operators, couriers, IOSS intermediaries) at lodgement via AES/ICS2 systems. The fee covers administrative costs of clearance, risk analysis, and physical inspections, distinct from customs duty (zero for ≤EUR 150) and import VAT. It must be itemized separately on customs invoices. An estimated 150M parcels enter Poland annually; non-EU vendors selling DDP must factor this into landed costs. Declarants must update IT systems for fee calculation and payment reference (NRB) generation. Non-payment triggers declaration rejection (error CUS-ERR-409) and storage charges. The European Commission will review the fee level after 12 months.

Polish Investment Zone (PSI) Revamped: Simplified Entry, Stricter Monitoring

The amended PSI Act entered into force November 1, 2026. New permit applications are simplified: the “substantial contribution” test replaced by minimum investment thresholds (PLN 10M large enterprises, PLN 3M SMEs) and job creation commitments. Existing permit holders face stricter annual reporting on employment and investment maintenance with clawback provisions. Eligible sectors narrowed (excluding real estate, financial intermediation). Aid intensity caps aligned with EU GBER 2023. Two-stage application: regional governor assessment, then Minister of Economy approval. First applications under new rules from January 1, 2027; existing holders must submit enhanced annual report by March 31, 2027. CIT exemption claimed in CIT-8; compliance verified within 5 years. MNCs benefit from streamlined new projects but face higher compliance for existing ones.

Temporary JPK CIT Exemption for Fixed Asset and Intangible Registers

A Minister of Finance regulation published October 30, 2026, suspends the requirement to submit JPK CIT structures for fixed asset registers (FA) and intangible/legal asset registers (IA) for tax years beginning after December 31, 2025, until further amendment. All other JPK CIT structures (GL, AR, AP, IN) remain mandatory. The exemption reduces administrative burden for capital-intensive sectors (manufacturing, energy, telecom, real estate) and IP-heavy industries (pharma, IT, R&D). Taxpayers must maintain accurate underlying records per Accounting Act and CIT Act; the relief applies only to electronic transmission. Ministry indicates a permanent SAF-T-integrated solution aligned with OECD BEPS Action 13 is under analysis. Penalties up to PLN 10,000 per filing error remain for mandatory structures.

KSeF Penalty Moratorium Extended to December 2027

The Sejm approved an amendment extending the moratorium on penalties for KSeF (National e-Invoice System) errors until December 31, 2027. The measure waives financial penalties for non-compliance or technical mistakes but does not suspend the obligation to issue invoices via KSeF. Mandatory adoption deadlines unchanged: large enterprises from July 2024, medium from January 2025, small from July 2025. The deferral covers administrative fines and tax-related sanctions. Businesses should use the extension to audit e-invoicing workflows, integrate ERP with KSeF APIs, and train staff. Failure to issue via KSeF may still trigger VAT deduction challenges for buyers. Ministry plans updated FAQs and technical specs by Q1 2027.

OECD Overhauls Intra-Group Services Transfer Pricing Guidance for AI Era

The OECD released draft guidance (October 2026) for the most comprehensive revision in decades of Chapter VII (intra-group services). The routine 5% mark-up safe harbor for low value-adding intra-group services (LVASI) is eliminated, replaced by a benefit test requiring demonstrable, measurable benefits to the recipient. Services incorporating AI, machine learning, or proprietary algorithms are explicitly excluded from LVASI treatment, mandating full comparability analyses and potentially higher arm’s length charges. A “DEMPE”-style functional analysis for services is introduced (Development, Enhancement, Maintenance, Protection, Exploitation of embedded intangibles). MNEs must document AI components, data inputs, training cycles, and model ownership. Cost allocation for shared AI infrastructure (cloud, data lakes) addressed. Effective 2027 fiscal years with one-year transition. Poland, Germany, France signaled adoption. Polish Ministry of Finance to issue national interpretation by Q1 2027. MNEs should map intra-group agreements, identify AI-driven services, prepare benefit test documentation, and review existing APAs.

New Joint VAT Liability for B2B Service Recipients from 2027

An amendment to the VAT Act passed by Parliament extends joint and several liability (odpowiedzialność solidarna) to recipients of specified services (advertising, accounting, IT, management consulting) starting January 1, 2027. Recipients liable for supplier’s unpaid VAT if they knew or should have known of fraud (due diligence test). Heightened due diligence required: verify VAT registration, check VAT whitelist (biała lista), confirm bank accounts on split payment register, retain documentation 5 years. Failure creates presumption of negligence. Construction services excluded; liability limited to VAT amount (not interest/penalties). Suspicious transactions must be reported to KAS within 14 days. Ministry to publish high-risk NACE codes and due diligence checklist by November 2026. Businesses must update procurement policies, integrate whitelist checks into ERP, train AP staff. Applies to domestic and cross-border B2B services with place of supply in Poland.

Expansion Relief Abolished; Robotization Relief Extended with Depreciation-Based Settlement

Draft amendment UD461 (public consultation October 20) proposes abolishing the expansion relief (ulga na ekspansję) entirely from PIT/CIT Acts effective January 1, 2027. Taxpayers with undeducted qualifying expenses lose future deductions. Conversely, robotization relief (ulga na robotyzację) extended 10 years to 2036 but settlement method changed: the additional 50% deduction (on robots, automation software, integration) will be spread over the asset’s depreciation period (5-10 years) instead of one-off deduction. Companies must adjust tax depreciation schedules from 2027 and include qualification statement in annual return. Affected businesses should accelerate eligible expansion expenditures into 2026 and review automation pipelines.
