Taxes, Law and Optimization PL/EU - Introduction

DISCLAIMER: Educational content, not tax/legal advice. Consult a tax advisor. Laws as of 2026.

Hook: Why do the best traders go bankrupt in April?

You make 200,000 PLN on crypto. You are king. April comes. Your accountant says: “You have 38,000 PLN to pay, and you didn’t deduct commissions, you have no TXID, the broker didn’t give PIT-8C. And you also declared CFD incorrectly.” From 200k, 140k remains after corrections, interest and fixes.

This course was created so that story never happens to you.

6. Your first checklist - what to prepare BEFORE start

1. Why is this important for a trader?

Because taxes are the only cost you cannot avoid. You can reduce spread by changing broker. You can reduce tax only with knowledge.

3 reasons why taxes are part of edge:

1. Net edge, not gross. Strategy with 20% annually and 19% flat tax is actually 16.2% net. If you miscalculate NBP rates, your backtest lies by 2-4%.
2. Leverage of legality. IKE/IKZE is 0% Belka tax. Estonian CIT is 0% until distribution. It’s free tax leverage.
3. Peace of mind = better decisions. Trader who fears tax office closes positions too early, doesn’t average, doesn’t hold long-term portfolio.

Example: Trader employee (120k annually) + 80k from stock trading. On employment has PIT-11 and 32% second threshold. If he doesn’t know that PIT-38 is 19% regardless of scale, he thinks he will pay 32%. Fear blocks him from scaling.

2. Who is this course for - and who it’s NOT for

For YES:

• You have > 10 transactions annually
• You have a foreign broker (IBKR, DEGIRO, XTB Intl, Bybit, Binance)
• You account for crypto staking / LP / futures
• You consider JDG or LLC for trading
• You want to start a company in Estonia / Cyprus / UAE
• You have > 20k profit yearly - then optimization returns 10x

For NO:

• You have only IKE and Polish ETF and don’t exceed dividend allowance - PIT-8C is enough
• You’re looking for “how not to pay taxes” - we don’t teach that. We teach how to pay less, legally.
• You don’t want to keep records - without records there is no optimization.

3. Course structure - 7 lessons you must go through in order

Recommended path: 1 week = 1 lesson + exercises.

4. How to work with course - tools

Prepare before start:

1. Google Drive: folder Trader_Taxes_2026 with subfolders /PIT-8C /Foreign_Broker /Crypto_TXID /Costs /JDG
2. Google Sheets: 3 registers - we will show template in lesson 06
3. Tools: Koinly (trial), CoinTracking, NBP API (table A), e-Tax Office account (trusted profile)
4. Documents: PIT-8C from last 2 years, transaction history from brokers (CSV), deposit/withdrawal history, W-8BEN confirmations

Formula for your goal in this course

Net_Profit = Gross_Profit - Effective_Tax - Costs_(Accountant+Tool)

Goal is to minimize Effective\_Tax legally, not Gross\_Profit.

5. Legal status for 2026 and disclaimers

We base on:

• PIT Act art. 17, 30b, Journal of Laws 2026, crypto as monetary capital since 2019
• CIT Act, Estonian CIT since 2021, changes 2023-2025
• ATAD Directive, Polish CFC art. 24a CIT
• Interpretations KIS 2024-2026, NSA judgments regarding CFD as PIT-36
• KSeF from 2026 - mandatory for JDG VAT

What may change after 2026-05-13? Lump sum rates, Estonian CIT limits (revenue 100M?), UAE rates (9% above 102k USD), IKE/IKZE thresholds.

Therefore each lesson has a section “What to check in 2027”.

6. Your first checklist - START

Before you go to lesson 01, do this in 45 minutes:

• Download PIT-8C from all Polish brokers
• Download Annual Tax Statement from IBKR/DEGIRO/eToro
• Download CSV transaction history (last 12 months)
• Check if you have active W-8BEN (IBKR -> Settings -> Tax Forms)
• Create Drive folder with 5 subfolders
• Create empty Google Sheets “Trader_Register_2026”
• Log into e-Tax Office and check if you have historical UPO

Intro exercise: Calculate rough estimate: how much tax did you pay in 2025? How much commissions? How much swap/overnight? Enter into sheet. This will be your benchmark. After course you will return to this number.

Summary

After this course you will not become a tax advisor, but you will be a conscious advisor client. You will speak accountant’s language, bring him 3 registers instead of 200 pdfs, and you will know when his advice “let’s put it in costs” makes sense and when it’s asking for an audit.

Next step: Lesson 01 - PIT-38 vs PIT-36 instrument map. There we will decide once and for all: where CFD, where stocks, where crypto.

Good luck. And remember - tax office likes a trader who has order.
