Where to find field 52630 and 52670?
Field 52630 was code 5263, and field 52670 was code 5267 in the prior-2019 version of myTaxExpress software.
Field 52630 and 52670 are both part of the spouse's net income. They are needed when the taxpayer (not the spouse) is a new immigrant (so the taxpayer has an entry date on page 1 of T1) in the tax year. Field 52630 is the spouse's net income after tax payer's entry date; Field 52670 is the spouse's net income before the taxpayer's entry date.
Note: Field 52630 + Field 52670 must be EQUAL to field 23600 in the supporting worksheet. Otherwise, you will get a validation error.
You can find fields 52630 and 52670 when you click the spouse net income field on page 1 of T1. See these screenshots.
