Whether it's a question of how to prevent 500K in capital gains tax after living in your family home for 20 years, or planning in advance to make sure it never comes to that, you have options. I am not an accountant, but during this type of appointment I will help you workshop a plan that you can take to your CPA for tax planning. I will also supply the official IRS publications that explain the tax codes that will enable you to either eliminate, reduce, or defer the capital gains tax that would have upon selling your home.
