Good catch.
Canada Pension Plan (CPP) and Registered Retirement Savings Plan (RRSP) or Registered Retirement Income Fund (RRIF) are calculated differently. The following is right out of Turbo Tax help:
How are taxable Social Security benefits calculated?
Are your Social Security or Railroad Retirement benefits taxable? It depends on your income and your marital status. We'll figure it out for you based on the information you enter.
Here's how it works:
- We add up your total income, including your tax-exempt income and other adjustments the IRS requires
- Then we add one half of your benefits to this total
- Next, we compare this to a "base amount" (see below)
If the total is more than the base amount, some of your benefits will be taxable.
The base amount is:
$25,000 if you file as Single, Head of Household, or Qualifying Surviving Spouse
$32,000 if you're married and file a joint return with your spouse
$25,000 if you're married, you file separately from your spouse, and you and your spouse lived apart all year
$0 if you're married, you and your spouse file separate returns, and you lived together at any time during the tax year
