Commutative Property. An operation is commutative if you can change the order of the numbers involved without changing the result. Addition and multiplication are both commutative. Subtraction is not commutative: 2 - 1 is not equal to 1 - 2. Here are some examples of the commutative properties of addition and multiplication: 88 + 65 = 65 + 88. 153 = 153.
Another consideration is that SBP premiums reduce the retiree's taxable income and reduce out-of-pocket costs for coverage. SBP benefits are taxed as income to the survivor however the tax rate upon receipt of the annuity will generally be less than the member's current tax rate.

Payments from private and government pensions are usually taxable at your ordinary income rate, assuming you made no after-tax contributions to the plan. Annuities. If you purchased an annuity that provides income in retirement, the portion of the payment that represents your principal is tax-free; the rest is taxable. The insurance company that sold you the annuity is required to tell you what is taxable.
