The IRS will accept a valuation of private company common stock, if done by "the reasonable application of any reasonable valuation method." This includes:

  1. 1. The fair market value of tangible and intangible assets of the corporation;
  2. 2. The present value of future cash-flows; and
  3. 3. The market value of stock or equity interests in comparable companies.

The valuation may include other relevant factors, such as control premiums or discounts for lack of marketability, which are consistent with the standards laid out in IRS Revenue Ruling 59-60 regarding the valuation of private companies. Again, consistent with previous IRS valuation rulings, a valuation is considered reasonable if based on an appraisal by an independent appraiser as of a date that is within 12 months of the date for which the value is being determined. The IRS has also provided two other alternatives to an independent appraisal that are considered to meet the reasonable valuation test. One is a valuation of illiquid stock of a start-up company by experienced personnel, which may include employees or directors of the company. It would appear that a board of directors or a committee of the board of directors of a start-up company may do the valuation, where the board or committee is composed of experienced venture capitalists or private equity investors that have significant experience in valuing start-up companies. There are several additional requirements for this type of valuation to be reasonable, that are spelled out in the proposed regulations.

The other is a valuation based upon certain types of formulas. Examples of the formula-based valuation method would be valuing the stock based on a multiple of sales or earnings, or book value; however, for a formula-based valuation to qualify under the proposed regulations, it must be consistently applied to all valuations of the stock. Notice that this alternative valuation method will not be easily accepted by the government.
