There are two ways to put money in your NYCE IRA account: you can make contributions of earned income, and you can roll over assets.
Contributions can be made in the form of a check or money order to be deposited into your NYCE IRA account. You can also roll over assets, which are generally tax-free, as a distribution from a previous retirement plan or IRA.
2018 contributions must be received by the NYCE IRA Administrative Office prior to the tax filing deadline. In order for your contribution to be attributed to tax year 2018, the NYCE IRA Administrative Office must be in receipt of your contribution by April 10, 2019.
