I am in Michigan and am about to sell my Professional Corporation.
A major portion of this sale is Personal Goodwill.
What are the tax percentages for this Good will -- State and Federal?

I assume your corp is c corp then, to reduce double taxation on sale of the corp is to separate the intangible assets personally owned by you, known as the personal goodwill, from those owned by the corporation. By separating the assets, the gain from the sale of assets can be divided between the corp and you, the shareholder. By dividing the gain between assets owned by the corp and assets owned by you, a shareholder, one level of tax can be avoided on the sale of the assets owned by you. This reduces the amount of gain realized at the corporate level, thereby reducing the total tax liability upon liquidating the corp. Any gain on the sale of assets owned personally by you incurs only one level of tax at your individual capital gain rates. To the extent that goodwill exists in a corporate asset acquisition, you, as a C shareholder, may expect to retain about an additional 25 cents for every dollar of goodwill allocated to the individual rather than to the corp.

Thank you for the response. Where would I find the break-down of the graduated capital gains tax (ie. 15, 22, or more) for 2015?

Again, Thank You!
