Maximizing Tax Efficiency: How Betterment Uses Smart Tax Lot Selection to Reduce Your Tax Burden

When managing investments through a Betterment account, selling securities involves critical decisions that can significantly impact tax obligations. Each transaction, whether a withdrawal or rebalancing, triggers Betterment’s advanced technology to determine which securities and specific tax lots to sell. Through its tax-smart technology, Betterment aims to minimize the tax burdens associated with investments.

Understanding how tax lots are selected is essential for investors. The method of choosing which tax lots to sell considers both the cost basis of the security and the duration of its holding. This strategic selection process helps mitigate the overall tax impact of investment activities.

Tax lot basics and their impact on transactions

Every investment creates a unique tax lot, which serves as a record of the purchase, detailing the amount paid and the transaction date. The cost basis is crucial for tax reporting, as it dictates the profit or loss realized upon the sale of the security. For instance, purchasing $450 worth of a security, such as the Vanguard Total Stock Market ETF (VTI) at $100 per share, generates a tax lot reflecting 4.5 shares with a cost basis of $450.

Understanding cost basis reporting changes

Legislation enacted after the 2008 financial crisis transformed how brokers report cost basis to the IRS. This change underscores the importance of understanding your broker’s reporting method, as it directly influences taxable gains or losses. Brokers typically use a default method known as FIFO, or First In, First Out, which sells the oldest shares first. This approach may help avoid triggering short-term capital gains if older shares have been held for over a year.

While FIFO offers certain tax advantages, it does not account for whether the shares sold will yield a gain or a loss. This method often favors gains, as older shares are more likely to appreciate in value compared to recent purchases that may be temporarily down due to market fluctuations.

Betterment’s innovative TaxMin approach

Recognizing the limitations of FIFO, Betterment has developed a sophisticated algorithm to enhance tax efficiency during security sales, known as the TaxMin method. Initially relying on FIFO, Betterment has transitioned to this algorithm, which targets tax lots in a way designed to yield better outcomes for most investors.

When initiating a sale in a taxable account, Betterment’s algorithm first identifies which security to sell, aligning with the overall investment strategy. After pinpointing the security, the algorithm determines which specific tax lots to sell, emphasizing the minimization of taxes. For example, if a client holds multiple shares of VTI purchased at different prices, the TaxMin method analyzes these lots to select those that will ideally incur the least tax burden.

How TaxMin works to minimize tax liability

The TaxMin system operates on the principle of realizing taxable losses over gains, allowing short-term gains to mature into long-term ones, which are typically taxed at lower rates. This approach evaluates the cost basis of each lot to prioritize realizing losses before gains, maximizing tax efficiency for transactions.

Essentially, the algorithm is designed to facilitate the sale of shares by first targeting lots with available losses. If no losses are present, it seeks to minimize capital gains by prioritizing tax lots with the lowest capital gains, thereby optimizing the overall tax outcome.

Considerations for various tax situations

While TaxMin aims to reduce tax liabilities, some investors may benefit from a different strategy. For instance, those in lower income tax brackets or those expecting to face higher tax rates in the future might find it advantageous to sell assets at a gain initially, particularly if they can recognize capital gains at a 0% tax rate.
