Emigrant failed to inform payers of non-resident status

Have a couple that emigrated from Canada to Europe in Sep 2023. They are US citizens as well, so they have US Pension, Social Security, and Canadian work Pension (T4A), OAS and CPP, plus a T5 for some interest income. They didn’t inform any of the payers of their change in residency, so no NR4 slips.

I was going to file their emigrant return from Jan 1 to date of departure reporting their worldwide income up to that point. And then send in their slips to non-resident unit for a Priority Assessment as suggested by non-resident Part XIII unit.

But then I called the non-resident income tax unit and they said don’t send anything to Part XIII. Instead report the FULL amount on all the Canadian slips (T4A, T4AOAS, T4AP) on the part year return. Also report the US income and the T5 interest income only up to date of emigration and ignore the rest.

Any idea on the proper course of action?

Answered your own question, literally.

“report the FULL amount on all the Canadian slips (T4A, T4AOAS, T4AP) on the part year return. Also report the US income and the T5 interest income only up to date of emigration and ignore the rest.”

Ensure their credits are prorated for the emigration, as this may result in a higher liability. You need to also consider departure tax on any capital assets that are held within Canada. You can file an election to avoid this given you post collateral.

Generally, Part XIII should be captured within the proration of days the taxpayer was a non-resident within the year, that is why they are telling you to report all the income, as it makes up part of their liability (check your summary to make sure before finalizing). It’s normal to have little or no recourse on a newly emigrated taxpayer for the first year.

Subsequently, withholding tax would apply to income received from within Canada, but that is not really your problem at this moment…
