Simplified estimate: it does not apply the monetary devaluation coefficient (purchases more than 24 months ago) or the exemption for reinvestment in a permanent main residence, both of which can reduce the tax considerably. For residents, only 50% of the gain is taxed, added to your other income. Indicative values.

What are capital gains?

It's the profit you make when you sell a property for more than it cost you. That profit is subject to income tax (IRS), but only half (50%) enters the calculation, and you can deduct the purchase costs and works.

If you sold your permanent main residence and reinvest in another main residence, you may be exempt on the reinvested gain. The rules have details; it's worth confirming your case.
