Hi Happywife08,
Not sure of your situation but heres mine: My wife is Canadian and works full time and has 2 children. She filed her taxes this year and put us down as common-law. Straight away all her tax benefits stopped. Even though I do not work, do not have a SIN number, I still had to file my taxes for 2001 and 2012. I could not do that without a SIN, so I had to apply for a ITN ( International Tax Number ). I have that now. Taxes filed showing $0 income. My wifes tax credits are now starting to come back.
However, and no one in the tax office can explain this, what I earned in the UK in 2011 tax year BEFORE I came to Canada is taken into account! Hence why my wife owed some tax credit money
Something else I learned was: according to the CRA we are classed as common law THE DAY WE BEGAN
LIVING TOGETHER. Wheras for immigration purposes we are classed as common law only after we have lived
together for a year. That is why I wasnt on the tax returns for 2011, we thought we were not classed as
common-law.
Interesting I had to do the exact same thing but they didn't tell me d day we began living together was considered common law
So what I would say to you is get a tax number and file your taxes, even if your income is zero. Additionally the CRA wants to know your WORLD income, even if you are not working in Canada.
