Understanding German Income Tax

Before we dive into the strategy, you need to understand what you're actually taxed on in Germany. Your income tax isn't just calculated on your salary—it's based on your total taxable income, which includes:

• Employment income (your salary)
• Additional employment income (RSUs, VSOPs, etc.)
• Self-employment income (if you freelance or run a business)
• Rental income (from investment properties)

This last point — rental income — is crucial for what comes next.

When you own a rental property, you declare the rental income on your tax return (Anlage V). But here's the key: you also get to deduct all expenses associated with that property from your rental income. These deductions include:

• Mortgage interest payments
• Property management fees
• Maintenance and repairs
• Insurance
• Property tax (Grundsteuer)
• Building depreciation (Abschreibung für Abnutzung - AfA)

If your deductible expenses exceed your rental income, you create a rental loss. This loss doesn't just disappear — it reduces your overall taxable income, which means you pay less tax on your employment income.

Example: You earn €100,000 in salary and have a €10,000 rental loss from your investment property. Your taxable income becomes €90,000 instead of €100,000. At a 42% tax rate, that saves you €4,200 in taxes.

The key is in how you create that rental loss legally and strategically — and a particularly valuable tool is depreciation. This can turn a property that loses money on a monthly basis to being profitable after taxes.

How Depreciation Gets You Money Back

Depreciation (Abschreibung für Abnutzung, or AfA) is the most misunderstood — and most valuable — tax benefit in German real estate investing. Let's demystify it.

What Is Depreciation?

Depreciation is the accounting concept that buildings lose value over time due to wear and tear. In Germany, the tax code lets you deduct this theoretical "loss" from your taxable income — even though you're not actually losing money.

The key advantage: Depreciation is a non-cash expense. You don't spend a single euro, but you get to reduce your taxable income by thousands every year. The depreciation runs until the building value reaches zero - at 5% degressive depreciation you'll write off over approximately 20 years, at 2% linear it takes 50 years, and at 3% it takes 33 years.

What Can You Depreciate?

You can only depreciate the building itself, not the land. When you buy a property for €400,000, the purchase price is typically split:

• Land value: 20-30% (not depreciable)
• Building value: 70-80% (depreciable)

So on a €400,000 property, you might have €300,000 in depreciable building value.

Important: You can also depreciate renovation costs and improvements you make to the property — this is massive if you buy an older property and upgrade it.

Standard Linear Depreciation: The Baseline

The standard method is linear depreciation (lineare AfA), where you deduct a fixed percentage of the building value each year:

• Buildings constructed before 1925: 2.5% per year (40-year write-off)
• Buildings constructed 1925 or later: 2% per year (50-year write-off)
• New buildings (since October 2023): 3% per year (33-year write-off)

Legal basis: § 7 Abs. 4 EStG (Einkommensteuergesetz)

Example: €300,000 building value × 3% = €9,000 annual deduction

In this example, at a 42% tax rate, that could mean €3,780 in tax savings every year for 33 years.

The Big One: Degressive Depreciation (5%)

Since October 2023, there's a newer option worth understanding: degressive depreciation (degressive AfA) at 5% annually for the first years (§ 7 Abs. 5 EStG).

With degressive AfA, you can deduct 5% of the remaining building value each year instead of the fixed linear amount. This frontloads your tax benefits. You get bigger deductions early when they're most valuable.

How it works:

• Year 1: 5% of €300,000 = €15,000 deduction
• Year 2: 5% of €285,000 = €14,250 deduction
• Year 3: 5% of €270,750 = €13,538 deduction
• And so on...

You can use degressive for several years, then switch to linear when it becomes more beneficial (typically around year 8-10). This flexibility matters. Or you sell the property tax free after 10 years when the tax benefits become less significant.

Who qualifies: Only for newly constructed residential buildings where the construction permit was issued after September 30, 2023, AND you didn't start construction before October 1, 2023.

Illustrative tax savings (Year 1): €15,000 × 42% = €6,300 back through reduced taxes

Worth Knowing: Special Depreciation (Sonder-AfA)

On top of regular depreciation, you can claim special depreciation (Sonder-AfA) for certain new residential buildings (§ 7b EStG). This adds:

• 5% per year for the first 4 years (total of 20% extra deduction)

This is IN ADDITION to your regular depreciation (linear or degressive).

Requirements:

• New residential building
• Construction costs up to €5,000 per m² of living space
• Building permit issued in 2023 or later
• You can't live in it yourself (must be rented)

Combined power: In year 1, you could claim:

• 5% degressive AfA: €15,000
• 5% Sonder-AfA: €15,000
• Total first-year depreciation: €30,000

In this illustrative scenario, at 42% tax rate: up to €12,600 in tax savings in year one

Advanced: Heritage Protection Properties (Denkmalschutz)

Properties under heritage protection (Denkmalschutz) get the most accelerated depreciation benefits through three concurrent streams:

1. Enhanced renovation depreciation:

• 9% per year for 8 years, then 7% per year for 4 years on enhanced renovation costs
• Applies to modernization bringing the property to new-build standards

2. Standard renovation depreciation:

• 2% per year (linear) on standard restoration costs
• For work maintaining the old structure

3. Old building depreciation:

• 3% per year (linear) on the existing building portion
• Standard old building depreciation rate

Typical breakdown on a €400,000 heritage property:

• 72% renovation costs (€288,000):
  • 86% enhanced @ 9%/7%: €247,680
  • 14% standard @ 2%: €40,320
• 16% old building @ 3%: €64,000
• 12% land (not depreciable)

Year 1 depreciation:

• Enhanced: €247,680 × 9% = €22,291
• Standard: €40,320 × 2% = €806
• Old building: €64,000 × 3% = €1,920
• Total Year 1: €25,017

In this illustrative example, at 42% tax rate: €10,507 in potential tax savings in year one, continuing with three concurrent streams for 12+ years.

Requirements:

• Property must be officially listed for protection
• Renovations must be approved by heritage authorities
• Significantly more complex but extraordinarily tax-efficient

03 · The Numbers

12-Year Projection & Cashflow Analysis

Let's model a real-world scenario to see how this works in practice.

Your Situation:

• Annual salary: €100,000
• Tax bracket: 42%
• Current annual income tax: ~€32,000

Property Investment:

• Purchase price: €400,000
• Land value (25%): €100,000
• Building value (75%): €300,000
• New construction (eligible for degressive + Sonder-AfA)
• Financing: 100% at 4% interest
• Monthly rent: €1,500 (€18,000/year)
• Annual operating costs: €3,000

Key insight first: High interest rates on investment properties aren't bad if you can handle them — they're deductible. At 42% tax rate, a 4% mortgage effectively costs you 2.32% after taxes. Higher interest = larger deductions = bigger tax savings in early years.

Critical liquidity requirement: While after-tax calculations show profitability, you must be able to cover the pre-tax negative cashflow upfront each month. If a property loses €750/month before taxes, you need that available in your budget until you receive the tax refund. This is why many advisors emphasize the importance of stable income and emergency reserves. Pre-tax cashflow determines if you can afford it; after-tax cashflow determines if it's worth it.

Now let's see how this plays out in the complete cashflow picture.

Most people calculate rental property cashflow wrong—they only look at pre-tax numbers. Here's the framework:

Pre-Tax vs After-Tax Cashflow

Pre-tax (what most people only see):

• Rent: €1,500
• Mortgage: -€2,000
• Operating: -€250
• Monthly: -€750 ❌ "This loses money!"

After-tax (the complete picture):

• Rent: €1,500
• Mortgage: -€2,000
• Operating: -€250
• Tax savings breakdown:
  • Depreciation deduction (5% + 5%): +€525/month
  • Interest deduction: +€560/month
  • Total tax savings: +€1,085/month
• Monthly: +€335 ✓ Actually profitable

The "loss" is really forced investment into equity, funded by tax savings.

Timing & Receiving Tax Benefits

You receive tax benefits through:

1. Adjusted withholding (Lohnsteuerermäßigung) - get it monthly. Yes this is possible if you know how to file it.
2. Annual refund - lump sum when filing taxes

One common approach: Adjust withholding for better monthly liquidity, or build reserves knowing you'll get a large refund.

The Challenge: Finding These Properties

The math can work well, but finding properties that qualify for maximum depreciation (new construction, degressive + Sonder-AfA eligible) is the hard part. These properties are rare, highly sought-after, and often sold before hitting the public market.

04 · Is It For You?

Who This Strategy Works For

You've seen the numbers. Now the practical question: does this strategy make sense for your income?

Germany taxes your income in progressive zones — not as a flat rate. You don't pay 42% on everything you earn, only on the portion above ~€70,000. Your effective rate (what you actually pay on average) is much lower than your marginal rate (what each additional euro costs you). Property deductions reduce your income from the top down — so every euro you deduct saves you at your marginal rate.

Wherever you land today, the key takeaway is the same: understanding how depreciation and deductions work puts you ahead — whether you act now or later.
