Managing Deduction Types & Limits with BambooHR® Payroll

What are the different payroll deduction types, federal limits, and contribution amounts? How are they taxed and reported on the W-2?

Purpose: To help you understand each payroll-related deduction type, how it’s mapped on the W-2, and its contribution limits.


It is important to think of deductions in two categories—benefit deductions and non-benefit deductions. Benefit deductions are commonly those that make your employees excited, like healthcare or retirement, and help your employees, hence the name “benefit.” Non-benefit deductions are most commonly post-tax deductions like child support, cash advance repayments, garnishments, etc. BambooHR Payroll will help support both to ensure your payroll is all-encompassing and accurate. 

Deduction Types and Taxes

The table below maps out the different deduction types that sync to Payroll, its taxability, and which box each type is reported to on Form W-2:

Deduction Type Taxability W-2 Box Code Notes
401(a) Pre-Tax - subject to FICA tax and tax in some states Box 14 401a A governmental plan is an IRC Section 401(a) retirement plan established and maintained for the employees of: the United States or its agency or instrumentality; a state or political subdivision, or its agency or instrumentality; or an Indian tribal government or its subdivision, or its agency or instrumentality (participants must substantially perform services essential to governmental functions rather than commercial activities.)
401(k) Pre-Tax - subject to FICA tax and tax in some states
401(k) After Tax Post-Tax After-tax contributions to a 401(k) plan are similar to Roth contributions in that they're made with after-tax dollars and don't reduce taxable income in the year the employee makes them. Unlike Roth contributions, after-tax contributions aren't subject to the annual maximum limit.
401(k) Loan Repayment Pos-Tax Box 12 AA
401(k) Roth Post-Tax Box 12 BB
403(b) Pre-Tax - subject to FICA tax and tax in some states

408(k) - SEP Employer-only contribution - post-tax for the employee Box 12 F A Simplified Employee Pension (SEP) is a written arrangement (a plan) that allows an employer (including a self-employed individual) to make contributions toward its employees’ retirement without becoming involved in more complex retirement plans. A SEP must satisfy the requirements outlined in Internal Revenue Code (IRC) section 408(k), as well as the top-heavy requirements of IRC section 416 and the limitations on annual additions under IRC section 415. The contributions are made to traditional Individual Retirement Arrangements (not Roth or SIMPLE IRAs) of the plan participants. Under a SEP, IRAs are set up for each eligible employee.
408(k) - SEP Roth Post-Tax Section 601 of the Secure Act 2.0 allows employers to offer employees the option to treat employee and employer SEP contributions as Roth contributions (in whole or in part). Section 601 is effective for taxable years beginning after December 31, 2022.
408(p) - Simple IRA Pre-Tax - subject to FICA taxes and taxes in some states
408(p) - Simple IRA Roth Post-Tax Section 601 of the Secure Act 2.0 allows Simple IRAs to accept Roth contributions. Section 601 is effective for taxable years beginning after December 31, 2022.

Section 125 - Other Pre-Tax Section 125 - Other is optional and we do not report. Used for pre-tax plan types including Accident, Cancer, Critical Illness, Dental, and Vision plans. This plan deduction type is rarely used as those plan types are normally post-tax and don't qualify as Section 125.
Section 132/Commuter Benefit  Pre-Tax This deduction type is a compensation reduction agreement. A compensation reduction agreement is a way to provide qualified transportation benefits on a pre-tax basis by offering your employees a choice between cash compensation and any qualified transportation benefit. A compensation reduction arrangement can be used with a bona fide reimbursement arrangement. For each month, the amount of the compensation reduction can't exceed the monthly limits for transportation benefits described in Exclusion from wages, later.

The following deductions, ages, and federal limits are hard-coded in BambooHR. Please note that you will receive an error if the amount you enter for the employee's annual max exceeds the federal limits listed below.
