Taxing rental income: Everything landlords need to know about taxes on rental income

Anyone who rents out a property regularly generates income from letting and leasing. In principle, this rental income must be declared in the income tax return and taxed.

For many landlords, this raises the question of which income is taxable and which costs can be claimed for tax purposes. This is because, in addition to the income, numerous expenses related to the property can be deducted from tax.

The tax treatment of rental income follows clear legal rules. Structured documentation of income and expenses is therefore crucial.

In this article, you will learn how landlords tax rental income, which costs are deductible, and how to efficiently organize tax obligations in property management.

What does taxing rental income mean?

Taxing rental income means that income from renting out a property must be declared as part of the income tax return. For tax purposes, this income is treated as "income from letting and leasing".

In this process, the entire rent is not automatically taxed. The decisive factor is the so-called surplus of income over income-related expenses (Werbungskosten). This means: landlords only pay tax on the amount that actually remains as profit after deducting costs.

Income from letting and leasing

In German tax law, rental income is counted as income from letting and leasing.

This includes, for example:

• Income from renting out apartments

• Income from renting out commercial properties

• Income from renting out parking spaces or garages

This income must be declared in the income tax return.

Difference between income and taxable profit

The difference between income and the taxable result is important.

Landlords do not tax the entire rent, but only the surplus after deducting certain costs.

Example:

• monthly rental income: €1,200

• annual income: €14,400

• deductible costs: €5,000

In this case, only €9,400 must be taxed.

Which income from renting is taxable

Not only the monthly basic rent counts as taxable income. Other payments in connection with the rental can also be tax-relevant.

Typical taxable income

The most common rental income includes:

• monthly rental income

• Income from renting parking spaces or garages

• Allocations from service charge settlements

• One-off payments in connection with lease agreements

This income must, in principle, be declared in the tax return.

Treatment of service charges

Service charges are also considered income for tax purposes. At the same time, the corresponding costs can be deducted again as expenses.

This means:

• Service charges are initially booked as income

• Operating costs are deducted as income-related expenses

In practice, these amounts often balance each other out.

Which costs landlords can deduct from tax

A major advantage of renting out properties is that many costs can be taken into account for tax purposes.

These costs are referred to as income-related expenses (Werbungskosten).

Typical income-related expenses when renting

The most common deductible costs include:

• Maintenance and repair costs

• Property management fees

• Insurance for the property

• Property tax

• Interest on real estate loans

These costs reduce the taxable surplus.

Depreciation of the property

In addition to ongoing costs, landlords can also claim depreciation (AfA) for tax purposes.

In doing so, the value of the property is spread over many years for tax purposes.

Typical examples:

• Residential buildings are often depreciated over 50 years

• Around 2% of the building value can be taken into account annually

Depreciation is one of the most important tax advantages of real estate investments.

How the taxation of rental income works

Rental income is taxed as part of the annual income tax return.

In this process, income and expenses are compared.

Annex V in the tax return

Income from letting and leasing is declared in the so-called Annex V (Anlage V) of the income tax return.

Among other things, the following are entered there:

• annual rental income

• Service charges

• Income-related expenses

• Depreciation

The taxable surplus is calculated from this information.

Sample calculation for landlords

A simplified example shows how the tax is calculated.

Annual income:

• Rental income: €18,000

Deductible costs:

• Maintenance: €2,000

• Loan interest: €4,000

• Management costs: €1,000

• Depreciation: €3,000

Total income-related expenses: €10,000

Taxable surplus:

€18,000 – €10,000 = €8,000

Only this amount is taken into account in the income tax.

Typical mistakes when taxing rental income

Many landlords make similar mistakes when it comes to the tax treatment of rental income. These can lead to tax benefits not being used or to problems with the tax office.

Incomplete documentation of costs

A common mistake is the incomplete documentation of expenses.

Examples:

• missing invoices

• unrecorded repair costs

• unclear allocation of expenses

Without complete proof, costs often cannot be recognized for tax purposes.

Mixing private and rental-related costs

The clear separation of private and rental-related expenses is also important.

Typical problems arise when:

• Costs cannot be clearly allocated to the property

• private expenses are accidentally claimed as income-related expenses

Structured bookkeeping facilitates correct tax recording.

How landlords organize their property management efficiently

Structured management of tenancies also makes tax tasks easier. If income, costs, and documents are neatly organized, the tax return is much easier to prepare.

Structured documentation of income and costs

It is important for landlords to systematically record all relevant documents.

This includes:

• Lease agreements

• Invoices and receipts

• Service charge statements

• Documentation of repairs

Good documentation facilitates cooperation with tax advisors and tax offices.

Digital processes in property management

Digital solutions help landlords to organize management processes efficiently.

Typical advantages of digital real estate processes are:

• centralized document management

• structured management of tenancies

• better overview of income and costs

Anyone who rents out a property must tax the rental income generated. The decisive factor here is not the entire rent, but the surplus after deducting income-related expenses.

Many costs related to the property can be claimed for tax purposes and significantly reduce the tax burden. Clean documentation of income and expenses is therefore particularly important.

Digital processes and structured property management help landlords organize their documents clearly and fulfill tax obligations efficiently.
