Calculating Gain


In the state of California, property owners who decide to sell an investment property are subject to the following taxes:

  • 15% federal capital gains tax
  • 9.55% state capital gains tax
  • 25% depreciation recapture tax

Calculating the tax bill upon the sale of a property isn’t as hard as one might think, but it does require that you have a firm understanding of some basic principles. The first thing to understand is how to calculate the Adjusted Basis:

Formula Example
Net Purchase Price $500,000
(Depreciation) ($100,000)
Capital Improvements + $25,000
Adjusted Basis $425,000


Calculating gain is the next step to figuring out your tax bill.  Let's assume we sold our property for a net sales price of $1,000,000.  With that assumption we calculate gain as follows:

Formula Example
Net Sales Price $1,000,000
(Adjusted Basis) ($425,000)
Gain $575,000

With a computed gain of $575,000, we can now start applying the tax rates mentioned above to compute the total tax liability on the sale of the property:

Tax Formula Tax Owed
15% Federal Capital Gain 15% * (Gain - Depreciation) $71,250
9.55% State Tax 9.55% * Gain $54,913
25% Depreciation 25% * Depreciation $25,000
Total Tax Bill   $151,163
