NOL Planning for Small Business Owners 2026: The Advisory Playbook

Quick Answer: For 2026, net operating losses carry forward with no expiration. Yet each year they can offset only 80% of taxable income. Carrybacks remain off the table for most businesses.

Pro Tip: Always run the basis computation before the NOL model. Otherwise, your projection overstates the deduction by a wide margin.

Quick Answer: A loss year forces decisions across three to five future years. That multi-year scope, plus real dollar impact, justifies a separate advisory fee.

Compliance work answers one question: what happened last year? Advisory work answers a harder one: what should happen next? NOL planning for small business owners 2026 sits squarely in the second camp. Therefore, it should carry a second price tag.

The math doesn’t lie

Run the numbers on a typical engagement. A client with a $500,000 carryforward faces roughly $150,000 in future federal tax exposure. Smart sequencing might save $20,000 to $40,000 of that. Consequently, a $10,000 fee returns multiples of itself.

Owners accept that math readily. However, they never see it unless you show them. Build the comparison first. Then quote the fee.

What goes inside the engagement?

• A five-year carryforward absorption schedule with the 80% limit applied
• Depreciation election modeling across Section 179 and bonus
• QBI coordination so the deduction is not wasted
• Entity structure review for loss utilization
• Retirement plan timing in low-income years
• A written implementation roadmap with dates

Each item is a deliverable. Moreover, each one is defensible on an invoice. Our MERNA strategy framework sequences these pieces in the right order.

Why loss years create the best entry point

A client in a loss year is already worried. Therefore, attention is high. Meanwhile, the planning window is wide open because nothing is locked yet. That combination rarely repeats.

Firms that scale advisory work use software built for scenario modeling, not spreadsheets. Our entity-aware tax planning software runs multi-year projections across 1040s, 1120-S returns, and K-1s at the same time. As a result, you model the whole portfolio instead of one form.

How Do Section 179 and Bonus Depreciation Interact With NOLs?

This is the single most valuable distinction in loss-year work. Many preparers elect both without thinking. However, the two provisions behave very differently when income turns negative.

Section 179: capped by business income

Section 179 lets a business expense qualifying property in the year it is placed in service. For 2026, the maximum election is $2.56 million, up from $2.5 million in 2025. The phase-down begins at $4.09 million of qualifying property. Confirm these figures at the IRS Publication 946 depreciation guide.

Yet the taxable income limitation matters more for your clients. Section 179 cannot push a business below zero. Instead, the disallowed amount carries forward to a future year with income.

Bonus depreciation: no income ceiling

Bonus depreciation has no business income limit. Consequently, it can drive taxable income negative and generate the NOL itself. That makes bonus the lever you pull when you want a loss.

Sometimes you want the opposite. In that case, elect out of bonus by asset class. Then income stays positive and the QBI deduction survives. Review current bonus rules at the IRS bonus depreciation regulations page.

Feature	Section 179	Bonus Depreciation
Can create a loss?	No	Yes
Asset-by-asset election	Yes	By class only
Disallowed amount	Carries over	Becomes NOL
Spending phase-down	Yes, at $4.09M (2026)	No

The sequencing play that earns your fee

Take a client with $600,000 of equipment and $200,000 of projected income. Full bonus creates a $400,000 loss. Alternatively, a partial election holds income at $120,000 and preserves QBI. Model both. Then show the five-year difference.

That side-by-side comparison is the deliverable clients pay for. Furthermore, it is the moment they stop seeing you as a preparer. Ready to build this into your firm? Book a strategy session with our team.

How Does an NOL Affect the QBI Deduction?

Here is the trap almost nobody explains. The Section 199A loss carryforward runs on its own track. It is not the same as the NOL carryforward. Nevertheless, both reduce future benefit.

Two carryforwards, one loss

A negative QBI amount becomes a qualified business loss carryforward. Next year, it offsets positive QBI before the 20% calculation runs. As a result, the client loses deduction value they never knew existed.

Meanwhile, the NOL itself reduces taxable income. Taxable income also caps the QBI deduction. Therefore, the loss hits the deduction from two directions at once.

What changed for QBI in 2026?

The One Big Beautiful Bill Act widened the phase-in ranges starting in 2026. Joint filers now get a $150,000 range, up from $100,000. All others get $75,000, up from $50,000. Consequently, more specified service businesses keep partial deductions.

Filing Status	2026 Phase-In Range	2025 Phase-In Range
Married Filing Jointly	$403,501 to $553,500	$394,601 to $494,600
Married Filing Separately	$201,776 to $276,775	$197,301 to $247,300
All Other Filers	$201,751 to $276,750	$197,301 to $247,300

Verify these ranges against the official IRS QBI deduction page before you deliver a plan. Tax figures move. Your reputation should not.

How Do You Price an NOL Engagement at $5K to $15K?

 

 

Hourly billing destroys advisory margin. Instead, scope the engagement by outcome. Then anchor the fee to the dollars at stake.

A three-tier pricing ladder

• Tier 1, $5,000: Single entity, three-year carryforward model, written roadmap
• Tier 2, $9,500: Adds depreciation election modeling and QBI coordination
• Tier 3, $15,000: Multi-entity, five-year projection, entity restructure analysis, quarterly reviews

Present all three. Most owners choose the middle. However, equipment-heavy clients often reach for Tier 3 on their own.

How to run the sales conversation

Lead with the assessment, not the price. Show the client their carryforward absorption schedule first. Then show what happens with no planning. The gap sells itself.

Never discount to close. Instead, remove scope. A $5,000 engagement with clear limits beats a $9,500 engagement at half price. Furthermore, it protects your anchor for the next client. Explore how ongoing tax advisory relationships compound this revenue.

Turning one engagement into recurring revenue

An NOL spans years. Therefore, the engagement should too. Convert the initial project into a quarterly review retainer at $1,500 per quarter. Clients accept this readily because the carryforward keeps changing.

Entity structure often needs a second look as well. Many loss-year clients benefit from entity structuring and S corporation analysis once profits return. That is another engagement, naturally sequenced.

What Mistakes Cost Firms the Most on Loss-Year Work?

Every mistake below shows up in real practice. Moreover, each one is avoidable with a checklist.

Mistake one: modeling before basis

A partner cannot deduct a loss beyond outside basis. Likewise, an S corporation shareholder is limited by stock and debt basis. Build the basis schedule first. Otherwise your projection is fiction.

Next, apply at-risk rules. Then apply passive activity limits. Only after all three does the NOL computation begin.

Mistake two: assuming state conformity

States diverge sharply on NOL treatment. Some cap carryforward years. Others suspend deductions entirely in budget years. California, for example, has suspended NOL use in past periods.

Check the client’s home state before you promise savings. Furthermore, check every state where the business files. Multistate clients deserve a separate line item on your invoice.

Mistake three: giving the analysis away

This one costs the most. A loss-year client calls in December with questions. You spend six hours modeling. Then you bill nothing extra.

Stop that pattern immediately. Create a separate engagement letter for planning work. In addition, set a clear start date and deliverable list. Review real outcomes on our client results page.

Mistake four: ignoring retirement timing

A low-income year is often the wrong year for a large deductible contribution. Conversely, it may be the perfect year for a Roth conversion. For 2026, employee deferrals rise to $24,500 in a 401(k) and $17,000 in a SIMPLE IRA. Confirm limits at the IRS retirement contribution limits page.

Uncle Kam in Action: The Equipment-Heavy Contractor

Here is a hypothetical example of how this works in practice.

The Scenario. Imagine a solo CPA serving a general contractor organized as an S corporation. The business bought $850,000 of equipment and vehicles during the year. Revenue dipped because two projects slipped into the next year. Projected taxable income sits near $180,000 before depreciation.

The Challenge. The owner wants the biggest write-off possible right now. Full bonus depreciation would create a loss near $670,000. However, that loss would carry forward slowly under the 80% rule. Meanwhile, the qualified business loss carryforward would shrink QBI deductions for years.

How Uncle Kam Would Approach It. The advisor would first build a basis schedule for the shareholder. Next, the advisor would model three depreciation scenarios side by side. Scenario one takes full bonus. Scenario two elects out for five-year property. Scenario three uses a partial Section 179 election to hold income positive.

Illustrative Numbers. Under full bonus, the client pays zero tax now. Yet the carryforward takes four years to absorb. QBI value lost across that period could reach roughly $28,000. Under the partial election, the client keeps about $90,000 of taxable income. That income supports a QBI deduction worth roughly $18,000. Combined across five years, careful sequencing could save roughly $35,000 compared with the reflexive full-bonus approach.

The Engagement. This scope fits a Tier 2 or Tier 3 fee comfortably. The advisor delivers three scenarios, a five-year absorption schedule, and a quarterly review plan. Numbers are estimates and depend on facts. Nevertheless, the structure holds across most equipment-heavy clients.

Frequently Asked Questions

Can my clients still carry an NOL back to prior years?

Generally no. The TCJA removed carrybacks for most taxpayers. The 2025 legislation kept that rule in place. However, narrow exceptions exist for farming losses and certain insurance companies. Always check the specific facts first.

How long does an NOL carryforward last in 2026?

Post-2017 losses carry forward indefinitely at the federal level. Therefore, no expiration pressure exists. States may differ sharply, though. Several impose their own time limits or suspension periods.

Should I bundle NOL planning into the return fee?

No. Bundling destroys the perceived value of the work. Instead, use a separate engagement letter and a separate invoice. Clients respect the distinction once you explain the scope difference clearly.

How long does a typical NOL engagement take to deliver?

Most Tier 1 engagements take ten to fifteen hours. Tier 3 multi-entity work often runs thirty hours or more. Consequently, effective rates land well above compliance billing. Scope tightly and the margin holds.

What documentation should I keep for the carryforward?

Keep the loss-year return, the NOL computation worksheet, and annual absorption schedules. In addition, keep basis records and any elections made. The IRS may examine the loss year even after the statute closes on it.

Does an NOL affect self-employment tax?

No. The NOL deduction reduces income tax only. Self-employment tax is computed on net earnings from the business itself. Therefore, a carryforward offers no relief there. Explain this early to avoid disappointment.
