Mito del raise
Nunca rechaces un raise.
$47K → $52K scenario. Rechazar? NO.
Before.
Miguel $47K.
Before: $43,344 take-home.
After raise.
Miguel $52K.
After: $46,519 take-home.
$3,175 más take-home. Rechazar = pierdes.
Regla universal
Impossible. Nunca. Cliffs SÍ existen pero es different topic.
Carmen
Carmen almost lost $10K.
Near-miss.
Carmen, $95K → $105K.
Reaction: rechazar. Consultó CPA.
Brother explicated marginal system.
Net $6,540/año. Con compounds: $200K+ lifetime.
15 min math previno $400K error.
Standard deduction
Standard deduction = 0% bracket.
Deduct primero. Then brackets apply.
$14,600
$14,600 = 0% effectively.
$29,200
$29,200 = 0% for MFJ.
$21,900
$21,900 HOH.
Age 65+ o Blind
Age/blind = more deduction.
Itemize vs standard
Standard = default para 90%.
Filing status
Filing status matters.
Single
Highest rates.
MFJ
Penalty o bonus depende.
HOH
Missed most often.
MFS
Rarely worth.
Regla
MFJ default. HOH verify.
Cliff effects
Cliffs SÍ existen. Solo no en brackets.
Real cliffs vs bracket myth.
- 1
Roth IRA cliff
$240K MFJ cliff.

Charity timing
Bundle timing.
Conversion timing
Low-rate windows.
Inflation
Brackets ajustan con inflation.
Automatic adjustment protects.

|---|---|---|---|
| 2020 | $40,125 | $85,525 | - |
| 2021 | $40,525 | $86,375 | +1.0% |

| 2025 (proyected) | ~$48,475 | ~$103,350 | +2.8% |
Por qué matter
