Questions about this calculator
How is the comparison built?
Portuguese IRS against the other country's tax, with social security and a day count beside them - the three things a border decision actually turns on.
What is the day count for?
Residence and treaty positions follow the days you are present in each country. The calculator keeps the count so the tax view and the residency view agree.
Is this a treaty analysis?
It is the preview: a foreign-tax-credit look-through and an evidence list to take to an adviser, not a substitute for the full treaty review.
