One of the most frustrating things about the QBI deduction is this:
two business owners can run similar businesses, earn similar income, and get very different tax results.
The reason usually comes down to one factor most people overlook—income level.
If you’ve ever wondered why the QBI deduction seems generous for some people and completely unavailable for others, this article will make it clear.
QBI Is Not a Flat Rule
Many business owners assume the QBI deduction works the same way for everyone.
It doesn’t.
QBI is intentionally designed to change behavior as income increases. In other words, the tax code treats a lower-income business owner differently than a higher-income one—even if they run the same type of business.
This isn’t an accident or a loophole. It’s the point.
The Two Income Zones (Without the Math)
Instead of thinking about QBI in terms of numbers and tables, it’s more helpful to think in zones.
There is:
- a lower-income zone, where QBI works cleanly and predictably
- a higher-income zone, where additional rules begin to apply
Below a certain income level, QBI is relatively straightforward. Above that level, it becomes conditional.
You don’t need to know the exact cutoff to understand the concept. What matters is recognizing which zone you’re in.
Why Income Changes the Rules
Congress created QBI to encourage:
- business ownership
- job creation
- long-term economic growth
At lower income levels, the tax code assumes:
“This person is building something. Let’s make it easier.”
At higher income levels, the assumption changes:
“This person may already be doing well. Let’s be more selective.”
So instead of eliminating the deduction outright, Congress added filters—rules that decide who continues to qualify and who doesn’t.
Why Planning Works for Some People—and Not Others
This is where confusion often sets in.
You’ll hear things like:
- “Just restructure your business.”
- “Just change how you pay yourself.”
- “There’s always a workaround.”
Sometimes those ideas help.
Sometimes they do nothing.
The difference is income level.
Below the threshold, planning often isn’t even necessary.
Above it, planning may help—but only if the business qualifies under stricter rules.
And in some cases, no amount of planning restores the deduction at all.
Understanding this prevents wasted effort and false expectations.
A Real-World Example (Conceptual, Not Technical)
Imagine two business owners who both earn strong incomes.
Owner A:
- Runs a product-based business
- Employs staff
- Income is spread across systems and operations
Owner B:
- Earns income primarily from personal expertise
- Clients pay for skill, reputation, or advice
As income rises, the tax code treats these two situations differently—even if the dollar amounts look similar.
Why?
Because QBI is designed to favor businesses that scale beyond the individual.
This distinction becomes critical at higher income levels.
(We’ll explore this more in the next post on why certain professions lose the QBI deduction.)
Why Income Timing Suddenly Matters
Once income enters the higher zone, timing starts to matter.
Things like:
- a large one-time gain
- a bonus year
- selling an asset
- unusually strong business profits
can temporarily push income into a different zone—changing how QBI applies for that year.
This explains why:
- a deduction appears one year and disappears the next
- the same strategy produces different results over time
The rules didn’t change.
The income did.
The Most Common Mistake
The biggest mistake business owners make is assuming:
“If I qualified once, I’ll always qualify.”
QBI is recalculated every year, based on:
- total income
- business type
- how the income is earned
That’s why this deduction should never be assumed or taken for granted.
Why This Understanding Matters (Even Before Planning)
Before talking about strategies, structures, or optimization, there’s one essential question:
Does income level even allow planning to work?
If the answer is no, the smartest move is often acceptance—not force.
Clarity saves time, money, and frustration.
How This Fits Into the QBI Series
If this post helped you understand what the QBI deduction is, the next questions usually come fast:
- When does the QBI deduction change?
- Who qualifies — and who doesn’t?
- Why do some businesses lose it entirely as income rises?
To keep things clear, this series walks through those questions step by step.

The Bottom Line
The QBI deduction is not a universal benefit. It’s a targeted one.
As income increases:
- the rules change
- eligibility becomes conditional
- planning may help—or may not
Understanding this early prevents confusion later.
Once you grasp that income level controls the outcome, the rest of the QBI rules start to make sense.
