PTET vs. SALT Deduction for CRNAs: The 2026 QBI Tradeoff

Anesthesia machine illustrating the PTET versus SALT decision and its effect on QBI for CRNAs.

2026 CRNA tax strategy

PTET is no longer an automatic yes.

The higher SALT deduction changed the comparison. The income phaseout and QBI deduction make sure it is still not simple.

For several years, pass-through entity tax elections were close to a reflex for high-income S corporation owners. Pay the state income tax through the business, deduct it above the line for federal purposes, and sidestep the individual $10,000 state and local tax limit.

Then the federal SALT cap increased. For 2026, the headline limit is $40,400. That makes paying state tax personally more competitive for some CRNAs. It does not make PTET obsolete.

The answer now depends on four numbers: your income, total SALT, itemized deductions, and how much qualified business income deduction you actually receive. This is a tax projection, not a slogan.

The short answer

When does each route tend to win?

PTET tends to look better when:

  • Your personal SALT deduction is limited or phased down.
  • You would otherwise take the standard deduction.
  • Property tax and other state taxes already consume the personal cap.
  • Your CRNA business produces little or no usable QBI deduction.
  • The state credit and election rules work cleanly for all owners.

Paying personally tends to look better when:

  • Your full state tax fits beneath the available SALT cap.
  • You already itemize enough deductions to use the additional SALT.
  • You receive a full or partial QBI deduction from the business.
  • PTET would create state credit, timing, or nonresident complications.
  • You are not locked into a multi-year state election.

First, fix the headline number

The 2026 SALT cap is $40,400, until it is not.

For 2026, the federal deduction for state and local taxes is capped at $40,400 for most filing statuses. Married filing separately receives half. The increased cap begins shrinking when modified adjusted gross income exceeds $505,000, or $252,500 for married filing separately.

2026 headline cap $40,400
MAGI phaseout starts $505,000
Reduction rate 30%
Minimum cap $10,000

Why this matters for CRNAs: A household can have less than $40,400 of state and local tax and still be limited. At $600,000 of MAGI, the 2026 cap falls to roughly $11,900. The phrase “our SALT is under $40,400” does not finish the analysis.

The deduction also requires itemizing. If your total Schedule A deductions do not exceed the standard deduction, paying state tax personally may produce little or no incremental federal benefit.

Same state tax, different federal route

What PTET changes

PTET moves eligible state income tax from the owner’s personal return to the pass-through entity. The state generally gives the owner a credit for tax paid by the entity. Federally, the entity deducts the payment when computing pass-through income, subject to the applicable timing and state rules.

PTET route

The business pays

  • The entity claims a federal business deduction.
  • Pass-through income and federal adjusted gross income generally decline.
  • The payment is not trapped under the owner’s Schedule A SALT cap.
  • The same deduction generally reduces QBI.
versus
Personal route

The owner pays

  • The tax may be deductible on Schedule A.
  • The deduction is subject to the available SALT cap.
  • It helps only to the extent itemized deductions beat the standard deduction.
  • It does not reduce the business’s QBI.

The QBI tradeoff

A business deduction can shrink another deduction.

Qualified business income is the net amount of eligible income, gain, deduction, and loss from the business. If the S corporation pays $20,000 of PTET, the payment may reduce QBI by $20,000. If you were otherwise receiving a full 20% QBI deduction, that can reduce the deduction by as much as $4,000.

That does not mean PTET “costs” $4,000. It means you lose a $4,000 deduction. At a 32% marginal federal rate, the estimated federal tax cost would be $1,280.

One important correction: W-2 compensation paid to an S corporation owner is not QBI. If the business pays you a $150,000 reasonable salary and has $200,000 of eligible ordinary business income after expenses, the starting QBI is generally closer to the $200,000 business income, not $350,000.

CRNA businesses are generally specified service trades or businesses in the field of health. For 2026, the QBI deduction for an SSTB begins phasing out above $403,500 of taxable income for married filing jointly and $201,750 for most other returns. It reaches the end of the phaseout range at $553,500 and $276,750, respectively.
2026 filing status Full SSTB treatment through Phaseout range ends
Married filing jointly $403,500 $553,500
Single or head of household $201,750 $276,750
Married filing separately $201,775 $276,775

The thresholds use taxable income before the QBI deduction, not gross revenue or MAGI. The actual calculation can also be limited by taxable income, W-2 wages, qualified property, prior-year QBI losses, retirement contributions, and other business deductions.

Run a first-pass comparison

PTET versus personal SALT calculator

This screening tool estimates the federal difference between paying eligible state income tax through the business and paying it personally. It is designed to show which inputs are driving the answer, not to replace the tax projection.

Enter the household numbers

Use expected 2026 modified adjusted gross income
The same state tax being compared under either route
Property tax, other state tax, and local tax that remain on Schedule A
Mortgage interest, charitable gifts, and other allowable deductions excluding SALT
Enter 32 for a 32% marginal rate
Use the effective deduction on the marginal dollar of QBI
Personal-route SALT cap $40,400
Estimated cap after PTET lowers MAGI $40,400
Estimated federal benefit: pay personally $5,056
Estimated federal benefit: PTET $4,096
First-pass result Paying personally is ahead by about $960

The personal SALT deduction is usable in this example, while PTET gives up part of the QBI deduction.

This simplified estimate assumes the state PTET credit fully offsets the compared personal state tax. It does not model AMT, the overall itemized-deduction limitation, state addbacks, nonresident credits, ownership allocations, timing differences, prior QBI losses, the taxable-income QBI limit, payroll changes, penalties, or state-specific fees. Use it to identify the likely direction, then confirm the election with a complete federal and state projection.

The actual decision process

Five steps before making the election

Project federal MAGI and the available SALT cap

Calculate the 2026 cap after the income phaseout. Run it once before PTET and again after the expected entity deduction because PTET may lower MAGI.

Compare itemizing with the standard deduction

For 2026, the standard deduction is $32,200 for married filing jointly, $24,150 for head of household, and $16,100 for single or married filing separately. A SALT deduction below the cap still may not change federal tax if the household takes the standard deduction.

Calculate the real QBI effect

Use business income after reasonable compensation and other QBI adjustments. Then apply the SSTB phaseout, taxable-income limit, and any wage, property, or loss limitations that matter.

Review the state election and credit rules

Confirm the election period, deadline, eligible owners, payment timing, owner credit, addback, estimated-payment rules, and nonresident treatment. PTET is a federal workaround built out of fifty different state instruction manuals.

Model every owner, not only the entity

A multi-owner practice can produce different answers for different shareholders. Ownership percentages, residency, filing status, other income, and property taxes can make one election valuable for one owner and less valuable for another.

A cleaner example

Why the same $15,000 tax can produce two answers

Assume a married CRNA household has $450,000 of MAGI before PTET, $15,000 of eligible pass-through state tax, $18,000 of other SALT, $15,000 of other itemized deductions, a 32% federal marginal rate, and a full QBI deduction.

Pay personally

The full $33,000 of SALT fits

The $40,400 cap has not begun phasing down. Total itemized deductions reach $48,000. Compared with the $32,200 standard deduction, the incremental deduction is $15,800, worth roughly $5,056 at 32%.

Pay through PTET

The business deduction loses some QBI value

The $15,000 entity deduction is worth roughly $4,800 before QBI. A full 20% QBI deduction falls by $3,000, creating an estimated $960 tax cost. The remaining personal itemized deductions add about $256 of value. Estimated total: $4,096.

In this example, paying personally is ahead by about $960. Change MAGI to $600,000 and the personal SALT cap falls sharply. PTET can become the stronger route even after accounting for QBI. One variable moves and the answer flips. That is the entire point of the article.

Michigan CRNA businesses

Michigan calls it the Flow-Through Entity Tax.

Michigan’s FTE tax allows an eligible S corporation or partnership to pay tax at the entity level and gives owners a refundable Michigan credit for their allocated share. For 2026, the state individual rate is 4.25%, and the FTE rate follows the individual rate.

Three-year election

The election generally applies to the initial tax year and the next two years. A choice that looks good this December also needs to survive the next two tax projections.

Election deadline

For calendar-year taxpayers, the election window generally runs through September 30 after the end of the tax year under the rules effective for tax years beginning in 2024 and later.

Return and estimates

The annual FTE return is generally due March 31. Estimated payments are generally due April 15, June 15, September 15, and January 15 when the expected liability exceeds the applicable threshold.

Credit reporting

Beginning with 2025 returns, Michigan members must report required FTE credit information on the applicable owner forms attached to the Michigan individual or fiduciary return.

Michigan rules have changed several times since the FTE tax began. Use the state’s current FTE tax page and deadline calculator rather than relying on an old checklist saved in the firm’s shared drive.

Common mistakes

Where the quick comparison goes wrong

Using $40,400 as a universal cap

The cap phases down with income. A high-earning household may be much closer to the $10,000 floor.

Treating salary as QBI

Reasonable compensation paid by an S corporation is excluded from QBI. Start with eligible business income, not salary plus distributions.

Ignoring itemization

A personal SALT deduction has no incremental value until total itemized deductions exceed the standard deduction.

Assuming a full 20% QBI deduction

CRNA clinical services are generally an SSTB. The deduction may be full, partial, or zero depending on taxable income and other limits.

Comparing only one year

A binding state election can outlive this year’s income, property-tax bill, or filing status.

Waiting until the return is prepared

Election and payment deadlines may arrive before the tax return tells you what would have been better. Projections need to happen during the year.

The practical takeaway

Run both routes before moving the money.

PTET can still be an excellent deduction. The larger SALT cap simply means it is no longer the default winner for every S corporation owner. A proper comparison should show the available SALT cap, itemization benefit, QBI cost, state credit, timing, and multi-year election consequences on the same page.

That is the sort of tax work that belongs in a projection, not in a frantic message two days before an election deadline.

Frequently asked questions

PTET, SALT, and QBI questions

Is PTET still deductible federally in 2026?

IRS Notice 2020-75 provides that qualifying state income taxes imposed on and paid by a partnership or S corporation may be deducted by the entity when computing its federal taxable income. The federal treatment still depends on the payment meeting the notice and applicable state-law requirements.

Does the $40,400 SALT cap apply to every 2026 taxpayer?

No. Married filing separately receives half of the general amount. For other filing statuses, the $40,400 cap begins shrinking when 2026 MAGI exceeds $505,000 and cannot fall below $10,000. The MFS threshold and floor are also halved.

Does a PTET payment always reduce QBI?

A deductible entity-level state tax payment generally reduces the pass-through business income used in the QBI calculation. Whether that changes the final QBI deduction depends on the taxpayer’s SSTB phaseout, taxable-income limitation, wages, qualified property, losses, and other adjustments.

Is an S corporation owner’s salary included in QBI?

No. Reasonable compensation paid by an S corporation to a shareholder-employee is excluded from QBI. The remaining eligible business income may qualify, subject to the Section 199A rules.

Can PTET help even when total SALT is below $40,400?

Yes. The cap may be phased down because of income, other SALT may already use the available cap, or the household may take the standard deduction. In those cases, an entity-level deduction can still produce federal value.

Can I decide on PTET when preparing the return?

Sometimes the state election window extends beyond year-end, but payment timing still matters for the federal deduction and state credit. Election, estimate, return, and credit-funding deadlines differ by state. The safer habit is to project the decision before the final payment deadline.
