Which code relates to contributions made by government employees to tax-deferred retirement savings?

The correct choice pertains to Code G, which is specifically used for reporting contributions made by government employees to tax-deferred retirement savings plans, such as 457(b) plans. This code is significant because it highlights the contributions that are made from pre-tax income, allowing government employees to save for retirement in a tax-advantaged manner.

Understanding the context of tax-deferred contributions is essential for grasping broader tax planning strategies. These contributions reduce the taxable income in the year they are made, which can lower the overall tax burden for the employee. Additionally, funds in these accounts grow tax-deferred until they are withdrawn, typically during retirement when the individual's tax bracket may be lower.

The other options correspond to different types of contributions or retirement-related codes that do not specifically relate to contributions made by government employees. Familiarizing oneself with these codes and their purposes ensures a better grasp of retirement planning and tax reporting specifics.
