Carefully review your options before making a decision
When it come time to sell your corporation, you have two options. You can either sell the corporation stock or have the corporation sell the assets and distribute the proceeds. The tax implications of the two sales are very different. If you choose to sell the stock, you are the seller. The corporation is not affected by the transaction. The new owner steps into your shoes as the shareholder and takes over the existing corporation. If your share of the proceeds exceeds your basis in the stock, you'll have a capital gain to report on Schedule D.
If the corporation sells its assets, the corporation may close its doors. The assets could be sold to one person who intends to operate a business similar to yours, but does not want your corporation. The corporation return will reflect the sale of the assets. When the corporation liquidates, your share of the cash will be reported on Form 1099-DIV as a liquidating distribution. You'll use Form 1099-DIV to report the sale of your stock on Schedule D. Selling assets of the corporation could result in double taxation. The sale of the assets is taxable to the corporation and the liquidating distribution is taxable to the shareholder.
If you are selling the corporation stock for a loss, you may qualify for special tax treatment. It's a good idea to review the tax consequences of the sale with your tax advisor before making a move.
