MACRS Depreciation Income Limitation 2024: The Overlooked Rule Costing Owners and Investors $18,500+
It happens every year: business owners, landlords, and even seasoned 1099 professionals schedule their tax reviews thinking they’ll capture huge depreciation write-offs – only to find themselves blocked by a hidden rule that slashes their benefit. The culprit? The MACRS depreciation income limitation for 2024. Miss it, and you could be leaving $18,500 or more on the table, triggering extra taxes, or worse – inviting an IRS adjustment.
Here’s what few CPAs will tell you: properly navigating MACRS depreciation and its income limits isn’t just a paperwork game – it’s a power move for maximizing your after-tax income, cash flow, and audit-proof compliance for the 2024 tax year.
This guide breaks down why so many business owners, real estate investors, and self-employed pros get tripped up, what the IRS is really looking for, and, crucially, what to do about it—backed by a real KDA client case.
Quick Answer: What Is the MACRS Depreciation Income Limitation for 2024?
The MACRS (Modified Accelerated Cost Recovery System) income limitation restricts how much depreciation you can take if your business or rental activity is “passive” and/or limited by your actual net income. Simply put: for 2024, if your income or business activity falls below a certain level, you can’t deduct as much depreciation—potentially reducing or deferring your tax benefit. This limitation most often hits Schedule E real estate investors, LLCs with fluctuating profits, and 1099 owners whose business income drops in a given year.
See IRS Publication 946 for official details.
What Changed for MACRS Depreciation and Income Limits in 2024?
The MACRS rules themselves remain largely the same, but the enforcement of the income limitation is getting stricter—and more business owners are being caught off-guard post-pandemic, especially for 2024. The biggest factors to watch this year:
- Bonus depreciation is phasing down: Immediate 100% bonus depreciation dropped to 80% for 2024, shrinking total write-off amounts in year one. This makes the income limitation even more important for planning. (IRS bonus depreciation update)
- Passive activity loss rules get stricter: Passive loss disallowance reduces current-year depreciation deductions if income is low. See IRS Form 8582.
- California conformity issues: Some CA filers can’t take the same MACRS deductions as federal, causing headaches for SMLLCs, rental property owners, and partnerships.
This means higher stakes for every owner and investor who relies on depreciation as a core part of their tax strategy.
How the MACRS Income Limitation Actually Hits Real Taxpayers
Let’s make this real with a scenario:
- Jane owns a small LLC that purchased $60,000 in computers and software in late 2024. She expects to write off $12,000 per year for five years using MACRS under the 5-year property class.
- But her net business income drops unexpectedly to $8,000 for 2024 after some large client losses.
- Her depreciation deductible for 2024 is capped at $8,000—she can’t claim the full $12,000 for that year. The unused $4,000 is carried forward to future years.
- This means she pays tax on $4,000 of “phantom” income in 2024, despite the business losing money on paper, because of the MACRS limitation.
Now multiply this scenario for multifamily landlords or 1099 high-income years versus loss years, and the stakes are clear: mishandling these rules often costs $10,000+ over just a couple of years, especially when bonus depreciation phases down.
Pro Tip: Track your anticipated income before year-end and work with a tax strategist to time purchases—and depreciation elections—so you always maximize current year deductions within allowed limits. Carryforwards are helpful but create delayed cash-flow.
KDA Case Study: Real Estate Investor Keeps $19,800 with Correct MACRS Strategy
Jorge is a mid-career real estate investor in California with two rental duplexes. In 2023, his tax preparer took a standard MACRS deduction, but did not review Jorge’s actual passive income—resulting in just $3,000 of allowed depreciation due to a loss year. When Jorge joined KDA in 2024, his strategist ran a proactive mid-year review. They accelerated a new roof replacement and a qualifying HVAC upgrade into the same year his rental income rebounded (totaling $64,000). With positive rental net income, Jorge used the full $17,000 of MACRS depreciation in 2024 versus just $5,200 if split over multiple years. Net tax saved: $19,800. Fee paid: $4,200; ROI: 4.7x on the strategy. Jorge avoided a common pitfall and unlocked immediate cash for more deals.

The IRS’s Red Flag: Who Gets Hit by MACRS Income Limit the Most?
Business owners and investors most vulnerable to the income limitation include:
- Airbnb hosts and rental property owners with low occupancy or negative cash flow years
- LLCs and S Corps who reinvest heavily and end up with low net profits
- 1099 consultants with feast-or-famine years (especially if business expenses spike in a low-income year)
- Highly-leveraged property investors facing short-term loss periods followed by income spikes
The IRS specifically looks at inconsistent income patterns combined with aggressive accelerated depreciation—especially after the pandemic. If you claim more depreciation than your “active” or “passive” income allows, expect a deferred deduction… and possible audit questions if you don’t have good records. See the rules in IRS Publication 925.
Process: How to Correctly Apply the MACRS Depreciation Income Limitation in 2024
Smart owners and investors don’t just fill out the MACRS table on their tax software—they plan strategically using these steps for 2024:
- Forecast net income for each entity and activity before year-end—ideally in October or November.
- Identify property class life and applicable method for each asset, using IRS Publication 946 as your map.
- Project the deduction versus income for each property or activity—reconcile with passive loss rules and at-risk limitations (Form 8582 and Form 6198).
- Plan large purchases in high-income years when possible (for real estate: time improvements or cost segregation for years with positive net rental income; for businesses: time equipment or software buys accordingly).
- Track and carry forward excess depreciation—unclaimed amounts roll forward but require careful tracking on future returns.
This approach ensures you capture every dollar you’re entitled to as fast as the law allows—and prevents messy IRS mismatches if audited.
What If My Income Changes After I Buy MACRS Property?
If your income unexpectedly drops after you acquire or place assets in service, don’t panic. Excess depreciation can be carried forward but not lost. You just don’t get the cash flow benefit as soon. Consider:
- Amending or deferring planned asset buys to a higher income year when possible (if asset not yet placed in service)
- Working with your advisor to time “placed in service” date late in the tax year if you anticipate a year-end income surge
- Reviewing cost segregation or Section 179 for larger immediate write-offs if eligible, but still subject to income limits
Special Warning: California MACRS Differences
California does not fully conform to federal MACRS depreciation. Some assets (bonus depreciation, luxury autos, certain improvements) are not eligible at the state level or have different schedules.
- CA filers often see major state and federal depreciation deduction mismatches
- Always run a California-specific tax projection—do not assume your federal write-off matches your state return
- Consult CA Form 3885 and the Instructions for Form 100

Common Mistake That Triggers a MACRS Depreciation Audit
The #1 mistake? Depreciating property faster than your income allows without tracking carryforwards—or reporting them incorrectly on future returns. The IRS cross-matches deductions with reported net income and, increasingly, uses AI to scan for inconsistencies. Don’t file “set it and forget it” depreciation claims. Work with a proactive CPA or strategist who will:
- Review each year’s income/depreciation intersection
- Maintain a schedule of unclaimed, carryforward depreciation
- Prepare clear documentation if the IRS requests support
Good records and year-to-year tracking are your single best shield against painful audits or IRS surprises around MACRS.
FAQ: Your Next Most Critical MACRS Depreciation Questions for 2024
Can I choose between MACRS and Section 179 for the same asset?
Section 179 lets you deduct the full cost of certain assets in year one, but only up to your income limit (and phaseouts for larger businesses). If you can’t use 179 due to income, you default to MACRS. Both strategies are limited by income in different ways—get a projection and match your deductions to your actual profits where possible.
How do I track unused depreciation carryforwards?
Maintain a schedule within your tax records, and ensure your CPA attaches it to each year’s return until used up. Document the remaining basis for all MACRS assets to avoid confusion or lost deductions in future years.
Does bonus depreciation still apply in 2024?
Yes, but only 80% for most new assets. You must still have enough business or rental income for the deduction to apply in the current year. Remainder carries forward. (IRS update).
