Bonus depreciation is automatic, so doing nothing means taking it. The election out under IRC section 168(k)(7) is made by asset class, 5-year, 7-year, 15-year, on a timely filed return including extensions, and once made it is generally irrevocable without IRS consent. That asymmetry is the first planning fact: you rarely get to change your mind, so the elect-out case has to be clear before filing.
When electing out beats taking the deduction
A deduction is only worth the rate it offsets. The strongest elect-out fact patterns:
- A low-bracket year. A deduction that offsets 12% income this year is worth less than straight-line deductions offsetting 35% income over the next decade. Retirement-transition years, startup years, and loss years are classic cases.
- Expiring attributes. If a net operating loss carryforward or credits are already set to absorb this year's income, bonus adds deductions you cannot monetize.
- QBI interaction. The section 199A deduction is capped by taxable income; a large bonus deduction can shrink the QBI benefit enough to claw back a meaningful share of the apparent savings.
- State addbacks. States that decouple from IRC section 168(k) require you to add the bonus back and depreciate separately, which creates a second depreciation schedule and, in some states, a benefit that never fully returns.
- An exit on the horizon. Depreciation on 5-year and 7-year personal property is recaptured as ordinary income under IRC section 1245 at sale. Front-loading a deduction 18 months before a sale mostly converts the timing benefit into ordinary income with extra paperwork.
One bad reason: passive loss fear. If IRC section 469 suspends the loss, it is not wasted; suspended losses carry forward and release against future passive income or in full when you dispose of the activity. Electing out to avoid a suspended loss usually gives up value.
Worked example
A fund principal winding down W-2 work expects $60,000 of taxable income in 2026 but $400,000 or more annually from 2027 on. Her new $750,000 rental would generate a $140,000 bonus deduction. Taken in 2026, most of it offsets income taxed at low rates or becomes a loss she cannot use. Electing out of bonus for the 5-year and 15-year classes keeps the accelerated MACRS schedule from the cost segregation study, spreading deductions into her high-rate years. Note what she kept: the study still pays off, because electing out of bonus does not undo the shorter recovery periods.
Readiness check before you file
- Projected marginal rate this year versus the next 5 years
- NOL, credit, and suspended loss balances that already shelter this year
- QBI deduction with and without the bonus deduction
- State conformity for every state in the return
- Expected hold period for the property
