Generally speaking, Your RRSP limit is 18% your last year's income, but it is really depends on Revenue Canada, not on your calculation or your accountant.'s. :-)
So, if your T452 (Assessment of your income taxt return )for year 2000 was issued and granted you RRSP limit for $2000, then you can use it for year 2001 's purchasing RRSP, otherwise, if your limit is $0 for year 2000, like that in yr 2000, you have no fixed income in Canada, then you can not buy any RRSP until year 2002, any RRSP you bought will be used for your year 2002's income return. understood?:-)
