Deductions from your pay that are used to fund a defined benefit pension plan are generally after-tax contributions to the plan. As such they are not subtracted from the amount reported in box 1 of your W-2 and are not listed in box 12 of your W-2. They are also not deductible anywhere on your tax return. When you eventually received distributions from the pension, some portion of the distributions will be nontaxable investment in the contract.
No, they would typically be before-tax contributions. As such, they will be subtracted from your wage income reported in box 1 on your W-2 form. So, that portion of your wage income is not taxed. Thus, they are "before-tax" contributions.
