Calculate Your Historical Adjusted Cost Basis To Determine Your Real Net Worth – The Industry Leader in Cost Basis Analysis

Even though adjusting your cost basis is critical to calculating your capital gain/loss for tax reporting, it is also a crucial component of understanding your after-tax returns and ultimately your real net worth. A tax strategy without knowing your real net worth isn’t a tax strategy at all.


The desktop and online versions of the Netbasis application, with historical pricing and corporate actions, going back as far as 1925, will automatically calculate your adjusted cost basis in seconds, even when your securities have had complicated mergers, splits, spin-offs and other corporate events, and for a wide range of investment instruments.  Netbasis offers on demand, auto-completion of Forms 8949 and Schedule D.


With a record number of advisors moving from one firm to another, and firms continuing to merge and acquire other firms, client accounts are also in transition. Netbasis will reconstruct and verify cost basis information for Automated Customer Account Transfer Service (ACATS) or historical positions with missing or questionable cost basis within a client’s portfolio that is in transition, positioning you to provide a value-added to service to your clients.

Your clients with sizeable trading activity, such as hedge fund firms, are faced with the daunting task of sifting through large amounts of trade data to determine wash sale violations.

Tax Optimization

NetWorth’s Tax Optimization feature provides a powerful “What If” scenario feature that lets you enter your client’s objectives, such as “What would happen if I limited my gains to a certain dollar amount?” “What would happen if I wanted to maximize my capital gains by selling long term tax lots held for more than one year?”


You can define gain/loss objectives; select the gain or loss per share; choose from short or long-term gain/loss options; specify your goals for proceeds; and even enter the date of sale. Each time you adjust your scenario, you get your answer in seconds. The Tax Optimization tool easily facilitates your ability to neutralize tax obligations by factoring in past-realized gain/loss positions for tax lot harvesting on an easy to use screen.
