Marginal Tax Rate (Grenzsteuersatz)

The tax rate on your last euro of income

3 min readUpdated December 2024

Your marginal tax rate (Grenzsteuersatz) is the percentage of tax you pay on your next euro of income. For real estate investors, this determines how valuable tax deductions like AfA and mortgage interest are.

Germany's Tax Brackets (2024)

  • €0 - €11,604:0% (tax-free)
  • €11,605 - €62,809:14% - 42% (progressive)
  • €62,810 - €277,825:42%
  • €277,826+:45% (Reichensteuer)

Most German real estate investors fall into the 42% bracket

Why This Matters for Real Estate

Every euro you deduct (via AfA, mortgage interest, or expenses) saves you taxes at your marginal rate:

  • 25% bracket: €8,000 AfA = €2,000 tax savings
  • 42% bracket: €8,000 AfA = €3,360 tax savings
  • 45% bracket: €8,000 AfA = €3,600 tax savings

Real Example

Two Investors, Same Property:

Investor A: €45,000 salary

  • Marginal tax rate: ~28%
  • Total deductions: €25,000
  • Tax savings: €7,000/year

Investor B: €95,000 salary

  • Marginal tax rate: ~42%
  • Total deductions: €25,000
  • Tax savings: €10,500/year

Same property, €3,500 more annual benefit for high-income investor

Strategic Insight

Real estate is more attractive at higher incomes

The German tax system makes rental properties increasingly valuable as your income rises. This is why high earners often build portfolios of negatively-cashflowing properties—the tax benefits more than compensate for the monthly shortfall.

Income Tax + Solidarity Surcharge

Note: Your effective rate includes Solidaritätszuschlag (solidarity surcharge) of 5.5% of income tax. So the true 42% bracket is actually ~44.3% effective. This makes deductions even more valuable.
