Can I submit a previous year’s tax return using NETFILE?

The CRA’s NETFILE service accepts tax returns for the past four years. You can use TurboTax to NETFILE your returns for tax years 2018 and beyond during the 2021 tax season. For more information, visit CRA's Frequently asked questions page.

For tax returns prior to the 2018 tax year, you'll need to print and mail your returns to the CRA: T1 return contact.
