Use Case Example: Tax Planning Strategies

Case Scenario: Meet Bob and Jennifer, both married and filing jointly, tasked with selling $100,000 from their investment portfolios. However, their differing tax planning approaches yield contrasting results.

Bob rushes to sell his equities without a plan, leading to a hefty tax bill of $22,000 due to high income and capital gains tax rates.

In contrast, Jennifer's advisor utilizes Netbasis tools to craft a meticulous pre-tax sale strategy. By strategically selling specific tax lots with Netbasis' proprietary NetZero tax method and leveraging features like wash sale detection and market correlation replacements, Jennifer minimizes her tax liability, owing only $8,000 the following year.

This disparity underscores the importance of robust tax planning. With access to advanced tools like Netbasis, advisors empower clients to optimize portfolios and reduce tax burdens, enhancing their financial well-being.

Conclusion Notes

Bob did not use Netbasis and sold $100,000 in capital gains using the industry default FIFO method (First-In, First-Out), while keeping the rest of his portfolio invested.

Conversely, Jennifer and her advisor needed to take $100,000 in profits from her portfolio while minimizing her tax liability and keeping the rest of her portfolio invested. They used Netbasis to pre-determine how to offset half of her overall losses. Utilizing the Net Simulator feature, they identified alternative stocks with similar positive correlations (price movements) to those she sold at a loss. By partially selling the loss positions and replacing them with similar securities, Jennifer's tax liability was reduced by $11,349. This strategy allowed her to maintain her market presence while offsetting just half of her overall losses against her realized gains from the sale.
