Why Tanya Is Maxing Her 401(k)
At the 24% bracket, every dollar Tanya puts in her 401(k) saves her 24 cents in federal tax immediately. She's contributing $23,500 per year (the max), which saves $5,640 in federal tax alone. Her take-home drops from $7,720 to about $6,241/month, but she's effectively getting a 24% return on day one from the tax savings. before any investment growth.
She also does a backdoor Roth IRA ($7,000/year). No immediate tax break, but decades of tax-free growth. Between the 401(k), Roth, and her employer's 3% match ($3,600), she's putting away $34,100 per year toward retirement.
The 24% Bracket Cliff
Tanya is just barely in the 24% bracket. If she picks up extra shifts and earns $130K, the additional $10K is all taxed at 24% federal + 7.65% FICA = 31.65%. She'd keep $6,835 of that $10K. Still worth it, but it's a noticeable haircut compared to what she kept on her first $50K of income.
