Terms at hand: CFD (contract for difference) · Realized P/L · Position notional (notional value) · Break-Even · Tax residency · PIT-38 (Poland)
Consider a hypothetical Polish trader with PLN 250,000 annual taxable income comparing private PIT-38 with a limited company. The example assumes capital gains under classical CIT and includes tax when profit is distributed. First check the actual transaction classification before applying this comparison to another business.
Capital income and an operating loss do not disappear in one balance
The hypothetical limited company has correctly established PLN 20,000 capital-gains income and PLN 20,000 loss from other sources. Adding the results gives arithmetic zero. This does not mean the other-source loss removes the capital-income tax base.

The calculation for the capital income shown is 20,000 × 19% = PLN 3,800. The PLN 20,000 loss stays in its source; any later use requires a separate eligibility check. Before entering "CIT = 0", add a revenue source column and reconcile it with tax records. A combined portfolio or two-activity result does not replace classification.
Assumptions: Poland, ordinary limited liability company, tax year 2026, classical CIT. Correctly classified Article 7b income taxed at 19% and a separate other-source loss. No prior-year losses, deductions, special offsets or regimes altering the calculation. Minimum CIT and other company obligations are not modelled. Adding two results does not establish the complete accounting result. Official material: CIT Act, Article 7(1–3); MF: CIT loss deduction; MF: classical CIT rates.
Which income category can qualify for the reduced CIT rate?
Classical Polish CIT separates capital gains from other sources. The conditional 9% rate excludes capital gains; 19% applies to the capital income assumed here. Article 7b includes derivative income but has an exception for instruments hedging specified noncapital revenue or costs. Check the actual instrument purpose and statutory classification rather than saying the reduced rate can never apply to any derivative income.
The second modelled layer is a full dividend to a Polish individual shareholder, assuming nineteen-percent dividend PIT without exemption or treaty adjustment. Money retained in the company belongs to the company; it is not equivalent to money available for the owner’s private spending. The PLN 100,000 comparison below isolates these two tax stages and excludes other charges.
In the stated model, full distribution after 19% CIT and a 19% shareholder dividend charge gives 34.39% basic combined tax. Retaining profit leaves the same 81% before company running costs as the private 19% comparator. This model does not establish every personal or company obligation, every income level or every available regime.
Does the Estonian CIT rescue a pure trading company?
Estonian CIT can defer ordinary retained-profit tax for an eligible company. Hidden profits, nonbusiness expenses and other statutory events can nevertheless create tax before a normal dividend. Entry conditions, rates and shareholder credits need examination as part of the complete regime.
The Estonian CIT entry test includes less than 50% specified passive revenue in the prior-year total measured with VAT, including financial-instrument revenue. Examine all ownership, employment and other requirements and any applicable startup or small-taxpayer provisions. A newly starting company must not be assessed by an invented prior-year 100% ratio.
What fixed costs does a company carry that PIT-38 does not?
Add the actual administration, insurance and funding costs to the tax model. A company’s obligations differ from a private investor’s records and filing needs, but neither route has a universal zero-cost baseline. Use current quotes and the correct insurance titles instead of a fixed cost assumed for every trader.
No tax saving appears in the particular classical-CIT models shown below. That does not prove the result for every income level or structure. Examine income sources, separately applicable private charges, available regimes, actual costs and distributions alongside liability, joint ownership or succession aims.
What about a sole proprietorship on the lump-sum regime?
For private instrument income, PIT-38 is the ordinary Article 30b route. Business registration alone does not change that source. The Act also addresses disposals or exercise of rights occurring in business activity; evaluate the actual facts rather than asserting that own-account transactions can never fall within business activity. Availability of a revenue-based lump sum is a separate statutory question.
Compare legal forms only after establishing income classification and any available regime. Keep the private PIT-38 calculation as a baseline where it applies, and add actual company or business obligations to a separate model.
What are the real risks and traps of an LLC?
A company has register, accounting, financial-statement and applicable tax-reporting obligations. Check the required formats and deadlines for its financial year and reporting phase; not every company submits every listed JPK form on the same schedule. Proper accounting is mandatory where law requires it, but hiring an external accounting office is not a universal legal requirement.
Plan the actual liquidation process, creditor safeguards, records and tax consequences before incorporating. Separately, do not equate a small second holding with a single-member insurance title: Supreme Court resolution III UZP 8/23 of 21 February 2024 held that a 99% shareholder in a two-member company was outside the cited single-member-company social-insurance provisions. Simulated transactions and other insurance titles require their own factual assessment.
A worked example — Krzysztof and his 250,000-zloty question
In this invented example, the trader has correctly established PLN 250,000 taxable income and compares private nineteen-percent Article 30b treatment with classical company capital-income treatment. Assume full dividend payment to a Polish individual without exemption or treaty adjustment in Scenario B. Insurance and administration are separate variables, not a specified payable total.
At the assumed PLN 250,000 income, the basic 19% private calculation is PLN 47,500. The classical company-plus-dividend calculation is PLN 85,975, before other obligations. Retaining the assumed company profit leaves PLN 202,500 before running costs. These numbers support this model comparison, not a universal verdict that tax can never matter when selecting a structure.
What to do tomorrow — five steps before deciding on a company
Define the purpose of a proposed company and compare legally available treatments on your own facts. The models here show classical capital-income CIT and the cost of an assumed dividend; they do not exclude every tax reason for a structure. Assess liability, ownership, succession, accounting and insurance separately before committing to incorporation.
- Write down the intended purpose of the company. If the motive is tax, compare actual classified income, available regimes, other obligations and distributions; the particular capital-gains model here offers no saving. Liability, joint ownership and succession also require their own analysis.
- Book a paid consultation with a tax advisor registered on the KIDP roll, ideally one with clients from the financial sector. Ask for two variants run on your own numbers: PIT-38, and a company with revenue split across the two sources. It is worth preparing by reading our taxes section first, so you walk in with concrete questions.
- Obtain written administration quotes. Ask experienced accounting providers about monthly records, the annual statement and the applicable tax filings, including transaction volume and currencies. Compare coverage and any extra charges. Quotes inform the budget; three prices alone do not establish all company costs.
- Ask for the legal basis of a proposed regime. Check passive-revenue and other Estonian CIT conditions and the actual classification of trading activity. An individual ruling may clarify specified facts, but it is not the only available protection and does not universally eliminate earlier tax liability: official guidance distinguishes rulings obtained before and after the taxable event.
- Reconcile the applicable private settlement. Where Article 30b applies, retain separately recognised revenue and eligible costs, original currency amounts and the appropriate NBP conversion dates. Check the actual realisation events rather than only a final position close. Assess each proposed tax-deductible cost under the relevant provisions; neither usefulness nor an invoice settles every tool expense.
An invented classification counterexample concerns an ordinary importer with a USD 100,000 invoice. Assume hedge A actually meets Article 7b’s exception by securing specified noncapital operating revenue or costs and gives PLN 40,000 correctly established taxable income. Hedge B is instead an independent speculative position with PLN 40,000 capital income. If the company meets the nine-percent conditions for A, ordinary CIT is PLN 3,600; B at nineteen percent gives PLN 7,600, a PLN 4,000 difference. The model excludes other income and adjustments. Retain the linked obligation, exposure and period as evidence: a hedge label, or opening double the invoice notional, does not automatically classify the whole position as a qualifying hedge.

An ordinary company has PLN 20,000 capital income taxed at 19% and PLN 20,000 loss from other sources. What CIT arises on the capital income shown?
- PLN 0: the results sum to zero.
- PLN 3,800.
- PLN 1,800: the company can use 9%.
Check the answer and explanation
PLN 3,800.
Yes. Capital income shown is PLN 20,000 and 19% gives PLN 3,800. The separate loss does not reduce it in this model.
Frequently asked
Does a Polish LLC trading forex qualify for the 9% CIT rate?
Poland: the conditional nine-percent classical CIT rate excludes capital gains. Article 7b assigns specified securities and derivative income to that source but expressly excepts instruments hedging certain noncapital revenue or costs; special-entity provisions also need checking. An ordinary speculative capital-income model is therefore taxed at nineteen percent, while a correctly classified qualifying hedge needs a separate rate-eligibility check. Small-taxpayer status alone does not reclassify a transaction.
Does the sole shareholder of a Polish LLC have to pay social security (ZUS)?
Poland: a sole shareholder has a specified nonagricultural insurance title, but check actual coverage, concurrent titles and applicable bases before calculating payment. CEIDG start relief, preferential bases and Mały ZUS Plus do not automatically attach to that shareholder title. For health contributions, distinguish the relevant enterprise-sector fourth-quarter average wage from company income. Supreme Court resolution III UZP 8/23 of 21 February 2024 held that a ninety-nine-percent shareholder in a two-member company was outside the cited single-member social-insurance provisions. This does not decide simulated arrangements or other titles.
Does the Estonian CIT solve the problem for an own-account trading company in Poland?
Poland: examine all eligibility conditions of the company-income lump-sum regime. Article 28j’s prior-year test is less than fifty percent specified revenue measured with VAT, including disposal and exercise of financial-instrument rights. Startup and small-taxpayer rules have defined exceptions; do not invent a previous-year ratio for a newly starting company. Eligibility is not permanent permission, and hidden profits, nonbusiness expenses and other Article 28m categories can create tax before a normal dividend. A passive-income label alone does not complete the analysis.
Can I choose a sole proprietorship instead of a company for own-account trading in Poland?
Poland: classify the actual activity before comparing legal forms. Private qualifying Article 30b income is settled on PIT-38, and registration alone does not change its source. Article 30b(4) nevertheless addresses disposal or exercise of rights occurring in business activity, so own capital does not categorically exclude that treatment. Any revenue-based lump-sum eligibility is a separate statutory question. A Polish company has its own obligations and available regimes; insurance depends on actual titles, not a universal shareholder charge.
