Tax Planning for High-Earning Financial Consultants

As an advisor, your own practice is one of the most heavily taxed businesses in the code. Investment advisory is a specified service business, so the deductions other owners take for granted phase out fast as your income climbs. The right plan keeps them in reach.

Run the Numbers: Reclaiming the QBI Deduction You Lost

Because investment advisory is a Specified Service Trade or Business (SSTB), the 20% qualified business income deduction disappears entirely once a joint filer's taxable income clears about $553,500 in 2026. The fix is income timing. A large deductible retirement contribution can pull you back under the threshold, restoring the deduction and deferring tax at the same time. Assume an advisory couple with $560,000 in taxable income.
Above the SSTB Cap
QBI deduction denied

$0

At $560,000 of joint taxable income, you sit above the 2026 SSTB ceiling. As a financial business, the 20% deduction is fully phased out. A potential $46,000 write-off is lost entirely.
After Retirement Funding
QBI deduction restored

$46,000

A $160,000 deductible cash balance and 401(k) contribution drops taxable income to $400,000, below the threshold. The full deduction returns, and tax on the contribution is deferred for years.
Metric Above the SSTB Cap After Retirement Funding
Taxable Income (joint) $560,000 $400,000
Deductible Retirement Contribution $0 $160,000
Position vs 2026 SSTB Ceiling Above, deduction denied Below threshold
20% QBI Deduction Allowed $0 $46,000
QBI Deduction Restored, Plus Tax Deferred on the Contribution
$46,000 + deferral
For 2026, the SSTB QBI deduction phases out between $403,500 and $553,500 of joint taxable income and is denied above the top. Reducing taxable income below the threshold restores it. Figures are illustrative and depend on age, income, and entity structure.

Where RIAs and Brokers Quietly Overpay in 2026

These build on the fundamentals we cover on our consultants tax page and matter most once advisory income climbs into the phase-out zone. Four issues come up again and again with the practices we work with.

 
⚠ The SSTB Cliff

Your QBI Deduction Vanishes

Investment advisory and securities work are named SSTBs. Above roughly $276,775 single or $553,500 joint in 2026 taxable income, the 20% deduction is gone completely, not just reduced. Many advisors never realize they crossed the line.
⚠ The Salary Balancing Act

Your S-Corp Pay Cuts Both Ways

A lower S-corp salary saves payroll tax but shrinks the wages that support your deduction above the threshold. A higher salary does the reverse. Set in isolation, either number can cost you. The two have to be modeled together.
⚠ The State Tax Leak

You Skip the PTET Election

A pass-through entity tax election lets your firm pay state income tax at the entity level, where it stays fully deductible federally and sidesteps the personal SALT cap. It survived for service firms under current law, yet many advisors still miss it.
⚠ The Shelter You Outgrew

A 401(k) Alone Is Too Small

A solo 401(k) caps out long before a high-earning advisor's needs. Layering a cash balance or defined benefit plan unlocks far larger deductible contributions, and as shown above, can pull income back under the QBI threshold.

Who These Strategies Fit Best

These strategies reward advisors with real income at stake and a practice built to support them. Here is what tells us the moves above are worth modeling for you.
5 / 5 to be confident
Income at the Threshold
Taxable income near or above the SSTB phase-out, where the QBI deduction is shrinking.
An Established Practice
You run an RIA or brokerage business as a pass-through, not a W-2 paycheck.
Room to Fund Retirement
Steady cash flow that can support a 401(k) plus a cash balance or defined benefit plan.
A High-Tax State

You operate where a PTET election meaningfully lowers your federal bill.

A Multi-Year View
You plan to keep building the practice, since these structures reward consistency.

Expert FAQs

Why do financial advisors lose the QBI deduction?

Investment advisory is a Specified Service Trade or Business under Section 199A. For 2026 the 20% deduction phases out between roughly $403,500 and $553,500 of joint taxable income, and is denied entirely above the top of that range. Below the threshold, you can claim it in full.
Yes. The deduction is tied to taxable income, so a large deductible contribution to a 401(k), cash balance, or defined benefit plan can lower income below the threshold and restore it. You get the restored deduction and the tax deferral on the contribution in the same year.
Often, since it can reduce self-employment and Medicare tax. But your salary also affects the QBI calculation above the threshold, so the salary that minimizes payroll tax is not always the one that maximizes your deduction. The two need to be modeled together.
A pass-through entity tax lets your firm pay state income tax at the entity level, where it is fully deductible federally and bypasses the personal SALT cap. The final 2025 law kept this available to service businesses, so most advisory firms in income-tax states can still use it.
It depends on your age, income, and how the plan is designed, but the deductible limits run far higher than a 401(k) and rise as you get older. The plan needs an actuary to set up, so it works best when your income is strong and reasonably stable.
