Are you referring to Pension Splitting?
Is your wife's Disability pension a CPP benefit?

My Wife is getting a Disability Pension (Benefit) CPP.  I have claimed an early CPP and T4RIF income. If I make more than a certain dollar amount will they cut her off the disability pension?

Tony your info is very helpful! Thanks again.

For starters, CPP pensions of any sort are not eligible for Pension Splitting.
Your T4RIF income may be eligible for Pension Splitting, depends on age.
Your wife's CPP Disability Pension (before tax) should not be affected by your income, but her tax situation could be affected by reduction of non-refundable credits.

will pension splitting effect my husbands Canada Pension Disability benefits?

 

You split the pension when you file the tax return, so it will not affect the CPP since it is not eligible for pension splitting. 

 

The disability benefits amount is calculated in your earned income for registered retirement savings plan (RRSP)/ pooled registered pension plan (PRPP) purposes and will be used to calculate your RRSP/PRPP deduction limit. So the split pension is not considered an earned income.

 

I hope this was helpful
