Frequently Asked Questions

What is Cost Basis?

When you sell a security, such as shares in a company or a mutual fund, you must report the capital gains as taxable income. Capital gains are the difference between what you paid for the security and what you sold it for. What you paid for the security is called the “cost basis.”

If I don’t have the complete purchase date, can I still use Netbasis?

If all you have is the year or month and year but not the day of a purchase, you can enter that into the system and Netbasis will calculate an adjusted cost basis using the average of the high/low price for the year and/or month.

No. Netbasis will automatically account for any corporate activity that happened while you owned your stock and adjust the cost basis and shares accordingly.
