I have many clients with foreign limited partnership income reported on a T5013 in Box 104. However, the FTC page does not allow the assignment of foreign business income for LPs to a country. Subsequently, I must manually enter the income on the FTC page. In the Multiple Jurisdiction input, there should be some way to assign box 104 to a foreign country.
Thanks for asking about these points.
A positive amount in box 104, which posts to line 12200 of the T1, does get included in the calculation of CPP payable on self-employment income.
On these T5013 slips, I believe you are saying that they have an amount in box 104 as well as box 172, foreign tax paid on business income, but no amounts in the business income boxes for general partners (116, 120, 122).
As this is my first year with TaxCycle since 2014, I just had the chance to complete a live return with one of the LP returns. I managed to get the reporting correctly in TaxCycle, but the entry is counterintuitive.
