If I leave my family in Canada after landing, while I only start living in Canada say, after 3 years (in order to maintain my residency), then will I be required to pay tax during these 3 years while I am working outside Canada?
If so, how much will I be required to pay for a family of 6 persons? Will I be entitled to children tax benefits? How much?
If neither you nor your family are staying in Canada after landing, you will not be considered a resident for tax purposes and will not be required to pay tax in Canada on your world income for those 3 years before you settle. You will however not be entitled to child tax benefit either unless you and your children are living in Canada.
If you leave your family in Canada and only you live outside Canada for work reasons, you may be considered resident for tax purposes based on that you are keeping a second home in Canada and your family is in Canada enjoying services such as publicly funded health care and schools. In that case, your spouse can apply for child tax benefit for your children.
The taxes you must pay are based on your income and deductions, not on how many family members you have.
For child tax benefit, you can find a calculator here: http://www.cra-arc.gc.ca/bnfts/clcltr/cctb_clcltr-eng.html
Enter the number of children, your annual income, your spouses annual income and the UCCB income you are asked to report is child care benefit which would be $100 a month per each child under the age of 6.
