Cost basis regulations require reporting of the original value of assets at disposal to determine profit or loss for tax purposes. The US government issued more formal rules in 2008, requiring brokers and mutual funds to report cost basis. This generated discussion and critics argued it added to the cost of managing customer accounts.

Cost basis regulations are rules relating to cost basis accounting, where the original value of assets is reported at the time of disposal and is used to determine profit or loss. A classic example is presented for investors selling stocks. When they make the sale, they must report the cost basis and provide information about whether they made a profit or loss on the sale. This determines the tax liability, based on the size of the gain or loss.

A significant reform in cost base regulations occurred in the United States in 2008, when the government issued more formal rules for this process. This was part of legislation designed to stabilize the economy to deal with a financial crisis. Under the new cost basis regulations, brokers, mutual funds and other entities that transferred securities on behalf of clients were required to report the cost basis. This was a change from the past, where investors were responsible for this calculation, and some companies provided it as an optional add-on service.

These requirements mean that financial agents must keep highly detailed and accurate records on securities, using a consistent valuation method for investments such as mutual funds where individuals do not directly hold securities. When securities or shares are transferred, the agent must comply with cost basis regulations. In reports filed with the US Internal Revenue Service (IRS), they disclose the original cost of the asset and any profit or loss taken by the customer. They should also indicate whether it is a short-term or long-term gain or loss.

For investors, cost basis regulations require that your tax returns disclose your profits and losses. They can use the information provided by their agents on their own tax returns. If there are inconsistencies between the broker’s report and the investor’s report, this may trigger an investigation. It is important to review copies of tax returns sent to the IRS to confirm that the information is accurate. When it is not, investors can request a correction and an amended form to provide up-to-date and complete information to the government.

Within the financial industry, the updated cost basis regulations generated considerable discussion. Critics argued that they created a regulatory burden that added to the cost of managing customer accounts. Some also worried that it could create confusion, as there are various ways to handle cost-based accounting and disclosures. When a client wants to use a different method, it could create a mismatch between submissions that could lead to an audit.
