The Canada Revenue Agency’s Auto-Fill My Return (AFR) feature is a quick and easy way to download many of your slips right into H&R Block’s tax software.

When completing your return, you’ll be prompted to click the Sign in to My Account button, which will open a separate window containing the CRA’s My Account login page. If you don’t see this window, it’s possible your browser settings or a previously installed ad blocker might be preventing it from opening. You can adjust your browser settings by following these steps:

Google Chrome

1. Open Google Chrome.
2. In the top right corner of your screen, click the   or  icon.
3. Select Settings, then click Advanced.
4. Under Privacy and security, click Content settings.
5. Under Popups, click ADD next to Allow.
6. Enter the following URL to allow the popup window to open: http://www.cra-arc.gc.ca/esrvc-srvce/tx/ndvdls/myccnt/menu-eng.html.

Mozilla Firefox

1. Open Mozilla Firefox.
2. In the top right corner of your screen, click the icon with the three horizontal lines ().
3. Select Options, and then select Content.
4. Under Pop-ups, unselect Block pop-up windows, or choose to click Exceptions and choose which sites will be allowed pop-ups.

Internet Explorer

1. Open Internet Explorer.
2. Select the Tools button, and then select Internet Options.
3. On the Privacy tab, under the Pop-up Blocker, unselect the Turn on pop-up blocker checkbox.

If this doesn’t resolve the issue, you might have to disable the ad blockers that you’ve installed.

Note: If this is your first year filing a tax return, you won’t be able to use AFR or other services available through the CRA My Account; this is because the CRA requires that you file one tax return before you can register.
