PROVEN CLIENT OUTCOMES

Tax Planning Case Studies

See how Prosperl approached complex tax situations for High W-2 earners and business owners. Each example is based on a specific client’s facts; results vary.
These examples reflect specific client facts and tax rules in effect at the time. Results vary and are not guaranteed. This content is for general information and is not tax, legal or investment advice.

High W-2 Earners

High W-2 earners have fewer built-in deductions, making coordinated planning especially important. Each summary below explains the situation, the planning approach and what the reported number actually measures.

$137K Refund

High W-2 Strategy Stack

Client profile

Anonymous household with primary income from W-2 wages, equity compensation and limited business activity.

Measured result

A refund of approximately $137,000. Refund reflects tax already paid in excess of final liability; it is not the same as total tax savings.

Starting point

Withholding and estimated payments were set without a planning review, and available deductions and credits were not coordinated across the year.

Planning approach

A coordinated stack of timing, deduction and entity-adjacent strategies applied across the tax year, reviewed with the client before filing.

Scope and period

Single tax year, federal treatment. Prior payments and withholding levels materially affected the size of the refund.

Client responsibility

Client implemented recommended actions within required deadlines and provided supporting documentation.

$114K Refund

High W-2 with Real Estate and Timing Adjustments

Client profile

Anonymous high W-2 household that also held rental real estate alongside wage income.

Measured result

A refund of approximately $114,000, driven primarily by reduced final liability relative to amounts already withheld.

Starting point

Real estate activity was reported without a planning framework, and the timing of deductible items was not aligned with the wage income profile.

Planning approach

Real estate positions were reviewed for eligibility and documentation, and the timing of deductible items was adjusted so planning applied against the year's wage income.

Scope and period

Single tax year, federal treatment.

Client responsibility

Client maintained qualifying activity records and met documentation and participation requirements.

$74K Refund

High W-2 with Real Estate and Charitable Planning

Client profile

Anonymous high W-2 household with rental property and an existing charitable giving pattern.

Measured result

A refund of approximately $74,000. This reflects reduced liability against amounts already paid, not a cash gain beyond taxes paid.

Starting point

Charitable giving was unstructured and provided little tax benefit relative to the amount given.

Planning approach

Giving was restructured within recognized charitable planning rules and coordinated with the client's real estate positions.

Scope and period

Single tax year, federal treatment. Charitable vehicle and valuation details.

Client responsibility

Client funded and documented the giving strategy within the tax year and retained required substantiation.

“This example is based on a redacted client return. Results reflect that client’s circumstances and are not guaranteed.”

Business Owners

Entity design, timing and exit planning applied to owners with real operating complexity. Each summary states what the number measures and over what period.

$7.5M Tax Savings

$7.5M Tax SavingsProfitable S-Corp Owner with Multi-Year Planning

Client profile

Anonymous owner of a highly profitable S corporation with significant recurring income and succession considerations.

Measured result

Approximately $7.5 million in projected tax savings — a reduction in expected tax liability, not a refund or cash payment.

Starting point

The business was structured and taxed without a long-range plan, leaving recurring liability higher than necessary.

Planning approach

A multi-year plan covering entity structure, compensation design, timing of income and deductions, and long-term wealth and succession coordination.

Scope and period

Multi-year horizon. Taxes included, time period and realized-versus-projected.

Client responsibility

Client implemented structural changes, maintained compliance and sustained the plan across multiple years.

“This example is based on a redacted client return. Results reflect that client’s circumstances and are not guaranteed.”

12% Effective Tax Rate

$960K Income S-Corp Reaches a 12% Effective Rate

Client profile

Anonymous S corporation owner with roughly $960,000 of annual income from the business.

Measured result

An effective tax rate of approximately 12% for the year. Effective rate is total tax divided by the defined income base — it is not a marginal rate.

Starting point

Income was taxed at a materially higher effective rate with no coordinated planning across entity and personal returns.

Planning approach

Compensation, deductions and retirement and benefit structures were coordinated between the business and the owner's personal return.

Scope and period

Single tax year. Tax year, income base and whether federal, state and payroll taxes are included.

Client responsibility

Client adopted the recommended structures and maintained payroll and compliance requirements.

“This example is based on a redacted client return. Results reflect that client’s circumstances and are not guaranteed.”

Zero Federal Income Tax

Business Sale with a Seven-Figure Gain

Client profile

Anonymous owner selling an operating business that produced a seven-figure gain.

Measured result

Zero federal income tax on the gain from that transaction. This applies to the transaction, not to all of the client's income for the year.

Starting point

The sale was approaching without a pre-transaction tax plan, exposing the full gain to standard treatment.

Planning approach

Pre-transaction planning applied recognized provisions and timing to the structure of the sale, coordinated with the buyer's terms.

Scope and period

One transaction in a single tax year, federal income tax only. State treatment and any other taxes.

Client responsibility

Client engaged before the sale closed; the outcome depended on eligibility and on planning being in place prior to the transaction.

“This example is based on a redacted client return. Results reflect that client’s circumstances and are not guaranteed.”

How to Read These Results

Each case reports a different kind of outcome. These terms are not interchangeable, and the number alone never tells the whole story.

Refund

The amount returned to the client after filing, which can reflect overpayment, withholding correction, credits or an amended return. A refund is not the same as tax savings unless the underlying liability was actually reduced.

Tax savings

A reduction in the total tax that would otherwise have been owed, measured against a defined baseline and time horizon. Savings can be projected or already realized — each case notes which.

liability reduction

The change in tax owed for a specific year or transaction, before any refund or payment is applied. This is distinct from a refund, which reflects cash returned rather than liability avoided.

Effective tax rate

Total tax paid divided by a defined income base for a given year. The rate depends on which taxes are included — federal income tax alone, or federal plus state and payroll — and each case specifies that scope.
