S is for SPLIT. Income splitting is a strategy that involves transferring a portion of revenue from someone is actually in a high tax bracket to someone who is in the lower tax range. It may even be possible to reduce the tax on the transferred income to zero if this person, doesn't possess any other taxable income. Normally, the other person is either your spouse or common-law spouse, but it can also be your children. Whenever it is possible to transfer income to someone in a lower tax bracket, it must be done. If primary between tax rates is 20% your own family will save $200 for every $1,000 transferred to the "lower rate" significant other.
