Understanding the Wash Sale Rule and Its Tax Implications

By Brian Famigletti, Managing Director & Head of Marketing

What is the Wash Sale Rule?

The wash sale rule is an IRS rule that prohibits investors from claiming a tax loss from the sale of an investment if they repurchase the same or a “substantially identical” security within a 61-day window, starting from 30 days before the sale and ending 30 days after. 

This rule applies to investments beyond just stocks, such as contracts and options that would result in the investor acquiring the same security. The purpose of the wash sale rule is to prevent taxpayers from collecting tax benefits while maintaining essentially the same portfolio of investments. 

A violation of this rule disallows the loss, meaning it can no longer be used as a deduction to reduce taxable income. Then, the amount of the loss is added to the cost basis of the newly purchased security. On top of that, the original holding period is carried over as well.

What Triggers the Wash Sale Rule?

The wash sale rule applies to stocks, bonds, options, and other contracts to acquire securities. 

One of the most challenging aspects when trying to navigate the wash sale rule is defining what exactly constitutes a “substantially identical” security. The IRS does not provide a strict definition, so taxpayers must evaluate the material differences between two investments on their own. 

For example, two bonds issued by the same company may still be considered different if they have different coupons, maturities, or call features. On the flip side, shares of two separate funds with similar investment strategies could be considered identical. 

Investors must also be aware that the IRS considers all of their investments, not just those held within the same account. For instance, if an investor sold a security at a loss and their spouse repurchased that same security (or a “substantially similar” one) in a separate account, it could still trigger the wash sale rule. 

Additionally, investors with automatic dividend reinvestment programs may unknowingly purchase shares of a stock they just sold for a loss.

Tax Implications of the Wash Sale Rule

The main consequence of triggering the wash sale rule is that the investor is unable to immediately recognize a desired capital loss. Instead, the disallowed loss is added to the cost basis of the new security, postponing the tax benefit but not removing it entirely. Nevertheless, this can disrupt tax planning, particularly if investors are trying to offset gains in a specific year. 

The wash sale rule also has holding period implications. If the original shares were long-term holdings, that classification carries over to the newly purchased shares. This can actually be a positive for investors, as long-term capital gains are typically taxed at a lower rate. 
Avoiding the wash sale rule requires careful planning and coordination across investment accounts. Consulting with an investment manager like Griffin Asset Management can be a crucial part of thorough tax planning.
