Bookkeeping Basics for Entrepreneurs in Poland – KPiR, VAT, and Tax Settlements

Bookkeeping is one of those topics that can intimidate first-time entrepreneurs. In reality, the basics are not that complicated – especially if you run a sole proprietorship (JDG). This guide explains the key concepts, documents, and obligations related to bookkeeping for a JDG in Poland.

Types of Bookkeeping in Poland

Depending on your legal form and scale of operations, you may use one of three types of bookkeeping:

1. Revenue and Expense Ledger (KPiR)

The most popular form of bookkeeping for sole proprietors using the progressive tax scale or linear tax.

KPiR is a simplified form of records where you enter:

• Revenue (sales of goods and services)
• Deductible business costs (expenses related to the business)
• At the end of each month/year, you calculate income (revenue minus costs)

Who uses KPiR?

• JDG on the progressive tax scale
• JDG on linear tax
• Civil, general, and professional partnerships (if revenue does not exceed EUR 2 million)

2. Revenue Records

Simplified records for entrepreneurs using the lump-sum tax (ryczałt). You only record revenue – costs do not matter because ryczałt is a tax on revenue.

Who uses revenue records?

• JDG on ryczałt

3. Full Accounting (Accounting Books)

Mandatory for limited liability companies (sp. z o.o.), joint-stock companies, and other commercial law entities. Requires maintaining journals, general ledger, subsidiary ledgers, trial balance, balance sheet, and profit and loss statement.

Full accounting is significantly more complex and almost always requires a professional accountant.

KPiR – Step by Step

Structure of KPiR

The Revenue and Expense Ledger has 17 columns. The most important ones:

What Documents to Record?

In KPiR, you record events based on:

• Sales invoices – issued by you
• Purchase invoices – from suppliers and service providers
• Internal documents – e.g. business trip settlements, depreciation
• Cash register reports – if you conduct retail sales
• Bank statements – for bank fees and commissions

Entry Deadlines

• Entries should be made chronologically
• When maintaining KPiR yourself – by the 20th of the month following the month in question
• With an accounting office – the office has until the tax declaration deadline

Summaries

• Monthly – summing revenue and costs for the given month
• Cumulative – total from the beginning of the year to the end of the given month
• Annual – closing KPiR at the end of the tax year

Deductible Business Costs – What Can You Write Off?

This is one of the most important issues in JDG bookkeeping. A deductible business cost is any expense that:

1. Is incurred to earn, maintain, or secure a source of income
2. Is not on the list of excluded expenses (Art. 23 of the PIT Act)
3. Is properly documented (invoice, receipt, contract)

Typical Business Costs

Without limitations:

• Computer equipment and software
• Office supplies
• Outsourced services (e.g. hosting, subscriptions, advertising)
• Training and courses related to the business
• Business phone and internet (portion used for business)
• Business insurance
• Business travel (per diems, accommodation, transport)

With limitations:

• Passenger car – operating costs at 75% (if also used privately) or 100% (exclusively for business, with mileage log)
• Leased car – deduction limited to PLN 150,000 value (PLN 225,000 for electric vehicles)
• Entertainment – lavish expenses (e.g. expensive restaurants) are NOT deductible
• Advertising – fully deductible, but do not confuse with entertainment

Depreciation

Fixed assets valued above PLN 10,000 net cannot be expensed in full immediately. You must depreciate them – spreading the cost over the useful life.

Depreciation rates (examples):

• Computers: 30% per year (approx. 3.3 years)
• Passenger cars: 20% per year (5 years)
• Office furniture: 20% per year (5 years)
• Buildings: 2.5% per year (40 years)

Exception: One-off depreciation up to EUR 50,000/year (for small taxpayers and businesses in their first year) – popular among entrepreneurs buying expensive equipment.

Fixed assets up to PLN 10,000 net – can be expensed in full in the month of commissioning.

VAT – Value Added Tax

Must You Be a VAT Payer?

Not always. You can benefit from the subjective VAT exemption if:

• Your turnover will not exceed PLN 200,000 per year
• You do not conduct activities excluded from the exemption

Activities excluded from exemption (you must register for VAT from the start):

• Advisory and legal services
• Jewellery services
• Sale of new means of transport
• Sale of building plots
• Certain debt collection services

VAT Registration

If you want (or must) be a VAT payer:

1. Fill in form VAT-R
2. Submit it to the tax office (on paper or electronically)
3. Specify the date from which you want to be a VAT payer
4. The office confirms registration – you become an active VAT taxpayer

How Does VAT Work?

VAT is charged on sales and deducted on purchases:

Example:

• You invoice a service: PLN 10,000 net + 23% VAT = PLN 12,300 gross
• You buy a laptop: PLN 5,000 net + 23% VAT = PLN 6,150 gross
• Output VAT (from sales): PLN 2,300
• Input VAT (from purchases): PLN 1,150
• Amount due to the tax office: PLN 1,150 (2,300 - 1,150)

VAT Rates in Poland

• 23% – standard rate (most goods and services)
• 8% – residential construction, certain catering services, books
• 5% – unprocessed food, e-books
• 0% – export of goods, intra-community supply of goods
• exempt – educational, medical, and financial services

JPK_V7 – Mandatory Records

Since 2020, all active VAT taxpayers submit JPK_V7M (monthly) or JPK_V7K (quarterly). This is an electronic file combining the former VAT-7 declaration with purchase and sales records.

Deadlines:

• JPK_V7M – by the 25th of the month following the reporting month
• JPK_V7K – records monthly, declaration quarterly

Quarterly reporting is available to small taxpayers (revenue up to EUR 2 million).

Invoicing – Basics

What Must an Invoice Contain?

Every VAT invoice must include:

1. Date of issue
2. Invoice number (sequential, unique)
3. Seller details (name, address, NIP)
4. Buyer details (name, address, NIP)
5. Description of goods/services
6. Quantity and unit
7. Unit net price
8. VAT rate
9. VAT amount
10. Gross amount
11. Payment deadline (not legally required, but standard)

Invoice Without VAT

If you are VAT-exempt, you issue an invoice without VAT. Instead of the VAT rate and amount, you enter:

• "zw." – for subjective exemption
• The legal basis for the exemption

Invoice Timing

• General rule: by the 15th of the month following the month of sale
• Earlier issuance: up to 60 days before delivery/service completion
• Advance invoice: within 15 days of receiving the advance payment

Document Retention

You must retain invoices and other accounting documents for 5 years from the end of the year in which the tax payment deadline fell. Documents may be stored electronically.

Self-Accounting vs Accounting Office

Self-Accounting

Advantages:

• Cost savings (software cost: PLN 50–150/month)
• Full control over documents
• Better understanding of your finances

Disadvantages:

• Risk of errors
• Time-consuming
• Need to follow legislative changes

Best for: freelancers with a few invoices per month, service businesses without employees.

Accounting Office

Advantages:

• Professional service
• Lower risk of errors
• Time savings
• The office's liability for errors (professional insurance)

Disadvantages:

• Cost PLN 200–800/month (JDG)
• Less control
• Need to submit documents on time

Best for: businesses with more transactions, operations with employees, VAT payers with many invoices.

Online Accounting

Platforms like inFakt, wFirma, or Fakturownia offer:

• Automated invoicing
• Automatic KPiR generation
• Tax deadline reminders
• Bank integrations
• Cost: PLN 50–200/month

A good compromise between doing it yourself and full accounting office service.

Most Common Bookkeeping Mistakes

1. Lack of Documentation

Every business expense must be documented. A receipt without the company's NIP is not an accounting document (with minor exceptions).

2. Mixing Personal and Business Expenses

Only expenses related to the business can be deducted. Grocery shopping, everyday clothing, or family holidays are not business costs.

3. Missed Deadlines

Late tax payments or declaration submissions result in interest and can lead to penalties.

4. Incorrect VAT Rates

Applying the wrong VAT rate (e.g. 23% instead of 8%) creates reconciliation and correction problems.

5. No Mileage Log

If you want to deduct 100% of car costs, you must maintain a detailed mileage log. Without it – maximum 75%.

6. Ignoring Year-End Inventory

At the end of the tax year (31 December), you must prepare a physical inventory – this covers trade goods, materials, and finished products.

Financial Planning and Bookkeeping

Bookkeeping is not just an obligation – it is a source of information about your business health. Regularly analyse:

• Revenue vs costs – is the business profitable?
• Revenue trend – growing, declining, or stagnant?
• Cost structure – where is the money going?
• Liquidity – do you have enough cash for current obligations?

Freenance tools can help visualise this data and plan future cash flows, which is especially important in the first months of operation.

Summary

JDG bookkeeping does not have to be scary. Key principles:

1. Document everything – an invoice or other proof for every expense
2. Watch the deadlines – the tax calendar is your friend
3. Separate your finances – a separate business account is fundamental
4. Choose your tools – good software saves hours of work
5. Do not be afraid to ask for help – an accounting office is an investment, not a cost
6. Keep learning – tax regulations change every year

Remember: it is better to spend an hour understanding bookkeeping basics now than to pay thousands of zlotys for mistakes later.
