I just got off a 2 hour call with gusto and what I have learnt is that the W2 is mainly about what income you got from the company. Which is basically the money to your account or the Roth account, from the company account.The tax filing for the year the government is mainly concerned about what money you earned this year. So contributions to Roth from your personal account the government is not very interested and maybe you don't need to report it in your taxes.
