For the many members of the Arizona State Retirement System (ASRS), the nuances of paycheck deductions often slip by unnoticed, tucked neatly between health insurance fees and federal taxes on their paystubs. However, one particular aspect of these deductions, the pre-tax vs. post-tax contributions, merits a closer look, especially as they chart the course of their financial future.
As explained by the ASRS on their blog, "the 'Pension and Health Insurance Benefit' rate, which is a pre-tax deduction from your paycheck," accounts for the lion's share of the total contribution rate (11.86% of 12.00% for FY 2025-26). This pre-tax contribution, which is prominently listed as "ASRSRET" on paystubs, is accompanied by a smaller post-tax deduction, indicated as "ASRS LTD." This distinction is not just bureaucratic minutiae; it bears tangible effects on both current paycheck size and future tax obligations.
The practical upside to these pre-tax deductions is pretty straightforward. By lowering your taxable income now, pre-tax contributions mean "fewer taxes are taken out of your paycheck," as outlined on the ASRS blog. This immediate tax relief creates a more generous take-home pay. Yet, many retire, and they are struck with the realization - taxes are owed on the pension benefits they receive. Contrary to some retirees' beliefs, the taxes during their benefit phase are not a second taxation but simply the deferred taxes from their contribution period coming due.
The bewilderment some retirees feel upon seeing their pension checks reduced by taxes echoes a broader lack of understanding about retirement planning. "Some new retirees are surprised to see taxes taken out of their ASRS pension benefit when they start to receive retirement checks," reports the same ASRS blog post. The system functions akin to a 401(k), with pre-tax retirement plans being taxed upon withdrawal in retirement, rather than being taxed on both the front and back end.
For those craving a deeper dive into the essence of ASRS contributions, the ASRS website provides additional clarity. Whether it concerns the determination of rates, the fluctuation of expectations, or the intricacies of post-retirement taxation, further details await on their Contribution Rates page.
