About yearend

YearEnd helps startup employees optimize their equity and taxes, and can also file their tax returns. They simply connect their financial accounts and YearEnd will tell them how much tax they’ll owe and will make recommendations on how to make better decisions. At the end of the year, YearEnd can also file their tax return for them or they can collaborate with their existing tax accountant.
