In simple terms, the cost basis is what a person pays for the stock. The difference between the cost basis and the stock’s current price is called the net unrealized appreciation or NUA. The NUA is not subject to tax until the company stock is sold and will never be subject to an early withdrawal penalty.

How is an NUA taxed?

NUA relates to distributions of appreciated employer securities from an eligible employer-based retirement plan. When securities are sold, any NUA is taxed at the long-term capital gains rate. Any additional gain is taxed based on the holding period of the shares after they are distributed.

How do I report Nua on my taxes?

The total amount to report as NUA should be shown in Form 1099-R, box 6. Part of the amount in box 6 will qualify for capital gain treatment if there is an amount in Form 1099- R, box 3. To figure the total amount subject to capital gain treatment including the NUA, complete the NUA Worksheet on this page.

Is Nua subject to 10 penalty?

If you use the NUA strategy before you reach age 59½ or have separated from service before reaching age 55, and didn’t meet any other IRS exceptions, you may be subject to a 10% premature distribution penalty tax on the cost basis.

What does unrealized gain mean?

An unrealized gain is a potential profit that exists on paper, resulting from an investment. It is an increase in the value of an asset that has yet to be sold for cash, such as a stock position that has increased in value but still remains open.

What does unrealized appreciation mean?

An increase in the value of a property or other asset that the owner does not receive because the asset has not been sold. Unrealized appreciation occurs most commonly in real estate and securities because most other assets depreciate.
