Flat-Rate Tax vs. General Rules — Which Is More Profitable for Landlords

Flat-Rate Tax vs. General Rules — Which Is More Profitable for Landlords

Choosing the right taxation method is one of the most impactful financial decisions a landlord in Poland can make. The difference between flat-rate tax (ryczałt od przychodów ewidencjonowanych) and general rules (zasady ogólne, also known as the tax scale) can amount to thousands of zlotys per year, depending on your rental income, deductible expenses, and personal tax situation. Since 2023, following the Polish Deal (Polski Ład) tax reform, the landscape has shifted significantly, and many landlords who were previously comfortable with one method have found that the other may now be more advantageous.

This article provides a thorough comparison of both methods, explains the key factors that influence which is more profitable, and offers practical guidance for making an informed decision.

Overview of the Two Methods

Flat-Rate Tax (Ryczałt)

The flat-rate tax is a simplified taxation method where the tax is calculated on total rental revenue — without deducting any costs. Since 2023, it is the only available form of taxation for private rental income in Poland (rental income outside of business activity). The applicable rates are 8.5% on annual rental income up to PLN 100,000 and 12.5% on income exceeding that threshold.

The key advantage of the flat-rate method is its simplicity. You pay tax on what you receive, with no need to track and document individual expenses. The key disadvantage is that you cannot deduct any costs — including mortgage interest, renovation expenses, depreciation, insurance, or property management fees — from the tax base.

General Rules (Tax Scale)

Under general rules, rental income is taxed according to the progressive tax scale: 12% on income up to PLN 120,000 and 32% on income above that threshold. Critically, under this method, tax is calculated on profit — that is, revenue minus deductible costs. This means that all legitimate expenses related to the rental activity can be subtracted before the tax is calculated.

Important note: since 2023, general rules (tax scale) are available only if the rental is conducted as part of a registered business activity (działalność gospodarcza). Private landlords who rent outside of a business context are limited to the flat-rate method. This distinction is crucial and should be the starting point for any tax planning discussion.

Key Factors in the Comparison

Level of Deductible Expenses

The most significant factor in choosing between the two methods is the level of your deductible expenses. If your costs are low relative to your rental income, the flat-rate tax is usually more advantageous because the lower rate (8.5%) more than compensates for the inability to deduct costs. Conversely, if you have high deductible expenses — such as a large mortgage, significant renovation costs, or depreciation charges — the general rules may be more profitable because those deductions substantially reduce your taxable income.

Consider a practical example. Suppose you earn PLN 5,000 per month in rent (PLN 60,000 annually) and have deductible expenses of PLN 2,500 per month (PLN 30,000 annually). Under the flat-rate method, your tax would be 8.5% of PLN 60,000 = PLN 5,100. Under general rules, your taxable income would be PLN 30,000, and the tax (at 12%) would be PLN 3,600. In this scenario, general rules save you PLN 1,500 per year. However, this option requires conducting the rental as a business activity, which brings additional obligations.

Mortgage Interest

For landlords who financed their property purchase with a mortgage, interest payments are often the largest single deductible expense. Under general rules, mortgage interest (but not principal repayments) can be deducted from rental income. Under the flat-rate method, this deduction is not available. If you are still in the early years of your mortgage, when interest payments are at their highest, the general rules method may offer significant tax savings.

Depreciation

Property depreciation is another major cost item that can be deducted under general rules. The annual depreciation rate for residential properties in Poland is 1.5% of the property's initial value. For a property worth PLN 500,000, this amounts to PLN 7,500 per year in tax-deductible depreciation. Note, however, that since 2022, depreciation of residential properties purchased before that date can still be claimed under transitional rules, while properties acquired from 2022 onward are subject to different provisions. It is essential to verify current regulations with a tax advisor.

Administrative Complexity

The flat-rate method is significantly simpler from an administrative perspective. You need to keep a record of revenue received, but there is no requirement to track and document individual expenses. Under general rules, you must maintain detailed records of all income and expenses, retain invoices and receipts, and potentially file more complex tax returns. If you rent through a business, you also have to deal with business registration, ZUS (social security) contributions, and potentially VAT.

A property management platform like Brokik can help reduce the administrative burden under either method by automatically tracking rental payments, generating financial summaries, and keeping all documentation organized in one place.

Other Income Sources

Under general rules, rental income is combined with your other income (e.g., employment income) for tax purposes. If your combined income exceeds PLN 120,000, the excess is taxed at 32%. This means that for landlords with high employment income, the general rules may push them into the higher tax bracket, making the flat-rate method more attractive despite the inability to deduct costs.

When the Flat-Rate Tax Is Usually Better

• You rent privately (not as a business) — in this case, flat-rate is your only option since 2023.
• Your deductible costs are relatively low (below approximately 30-40% of rental income).
• Your property is mortgage-free or the mortgage is mostly paid off.
• You prefer simplicity and minimal paperwork.
• Your total rental income stays below PLN 100,000 annually (benefiting from the 8.5% rate).

When General Rules May Be Better

• You conduct rental as part of a registered business activity.
• You have high deductible expenses (mortgage interest, renovations, depreciation, management costs).
• Your total income from all sources stays below the 32% threshold.
• You are in the early years of a mortgage with high interest payments.
• You are willing to handle the additional administrative requirements of business rental.

Step-by-Step Decision Framework

To determine which method is right for you, follow these steps:

• Step 1: Determine whether you rent privately or through a business. If privately, flat-rate is your only option — and the analysis stops here.
• Step 2: Calculate your annual rental revenue across all properties.
• Step 3: List and total all deductible expenses: mortgage interest, insurance, property tax, management fees, repairs, maintenance, depreciation, and any other costs directly related to the rental.
• Step 4: Calculate the tax under the flat-rate method: 8.5% on revenue up to PLN 100,000 + 12.5% on revenue above PLN 100,000.
• Step 5: Calculate the tax under general rules: 12% on net income (revenue minus costs) up to PLN 120,000 + 32% above, remembering to add your other income sources.
• Step 6: Compare the two results and factor in the additional cost and effort of maintaining a business (ZUS contributions, accounting, etc.) if you choose general rules.

The Role of Professional Tools in Tax Management

Regardless of which taxation method you choose, maintaining accurate financial records is essential. Under the flat-rate method, you need reliable income tracking to ensure accurate tax declarations. Under general rules, detailed expense tracking is critical for maximizing deductions and supporting your tax position in case of an audit.

Brokik helps landlords keep their finances organized by automatically recording all rental payments, generating income summaries by property and period, and maintaining a complete financial history that can be exported for tax preparation. Having this data readily available saves time during tax season and reduces the risk of errors or missed deductions.

Important Considerations and Disclaimers

Tax regulations change frequently, and the information in this article reflects the general legal framework as of early 2026. Individual circumstances vary widely, and what is optimal for one landlord may not be optimal for another. Before making a final decision about your taxation method, it is strongly advisable to consult a qualified tax advisor who can assess your specific situation, including all income sources, existing tax obligations, and potential future changes to your portfolio.

Additionally, keep in mind that the choice of taxation method may have implications beyond income tax, including social security (ZUS) contributions, health insurance premiums, and VAT obligations. A comprehensive tax strategy should consider all of these elements together.

Conclusion

The choice between flat-rate tax and general rules is not a one-size-fits-all decision. It depends on your specific financial situation, the structure of your rental activity, and the level of your deductible expenses. For most private landlords in Poland, the flat-rate method is now the default (and since 2023, the only available option for non-business rental), offering simplicity and a competitive rate. For those who operate their rental as a business and have significant deductible costs, general rules may deliver meaningful tax savings — but at the cost of greater administrative complexity.

Whatever path you choose, keeping meticulous financial records is non-negotiable. A platform like Brokik provides the tools to track income and expenses effortlessly, giving you the data foundation needed for sound tax decisions and stress-free compliance.
