The construction and real estate development industry continues to operate in a complex tax environment in 2026. Between the phase-down of bonus depreciation, ongoing interest expense limitations, evolving state conformity rules, the changes from the One Big Beautiful Bill Act and increased scrutiny around credits and accounting methods, tax planning has become more technical and strategic than ever.
As a construction or real development company owner, CFO or accounting professional, the key question is not simply “What do we owe?” but rather “How can tax strategy support project profitability, cash flow and long-term growth?”
The industry is known for managing long project lifecycles, significant capital investment and multi-state operations. The most effective planning balances opportunity with compliance, accelerating deductions and deferring income where appropriate, optimizing credits and reducing risk through strong documentation and method alignment.
Below are five key tax planning areas we recommend evaluating in 2026.
Method of Accounting and Revenue Recognition Strategy
For your construction and development company, how and when income is recognized often has a greater tax impact than the rate applied to it.
Key considerations:
- Percentage-of-Completion vs. Completed-Contract Method (CCM): Contractors that qualify under the gross receipts test may still benefit from CCM for certain projects, allowing deferral of income until completion.
- Look-Back Interest Calculations: Long-term contracts accounted for under percentage-of-completion require look-back calculations, which can create unexpected interest income or expense.
- Small Contractor Exemptions: Companies under the gross receipts threshold may have additional flexibility in accounting methods.
- UNICAP (Section 263A) Considerations: Proper identification of capitalizable vs. deductible costs can significantly impact timing.
- State Method Conformity: Not all states follow federal method rules, creating SALT planning opportunities and risks.
Planning opportunity: Periodic method reviews can uncover deferral opportunities or identify situations where an accounting method change may improve cash flow.

Cost Segregation and Accelerated Depreciation Planning
With bonus depreciation phased down and long-term capital investment increasing across the industry, asset classification has become even more critical.
Key considerations:
- Cost Segregation Studies: Reclassifying building components into shorter recovery periods (5, 7, or 15 years) accelerates deductions.
- Section 179 Expensing: May provide additional planning flexibility for qualifying property.
- Qualified Improvement Property (QIP): Interior improvements may qualify for shorter lives if properly documented.
- State Depreciation Decoupling: Many states do not conform to federal bonus rules, creating multi-state timing differences.
Planning opportunity: A cost segregation study may yield meaningful tax savings particularly when paired with strategic entity structuring.

Interest Expense and Capital Structure Optimization (Section 163(j))
Construction and development projects are capital-intensive, and interest deductibility remains a significant planning area.
Key considerations:
- Section 163(j) Limitation: Interest deductions may be limited based on a percentage of adjusted taxable income.
- Real Property Trade or Business Election: Electing out of Section 163(j) may preserve interest deductions but requires use of ADS depreciation (longer recovery periods).
- Entity-Level vs. Partner-Level Impact: Flow-through entities require careful modeling of interest allocation.
- Related-Party Financing Structures: Must be evaluated for compliance and documentation.
- State-Level Limitations: States may apply different interest limitation rules.
Planning opportunity: Modeling debt structure, entity elections and depreciation trade-offs together can significantly impact long-term after-tax project returns.

Tax Credits and Incentive Optimization
Federal and state incentives continue to be a powerful driver of project economics, particularly in development.
Key considerations:
- Energy-Efficient Commercial Building Deduction (Section 179D): Available for qualifying energy-efficient construction and retrofits.
- Energy Credits (Solar, Storage, etc.): Transferability rules may create monetization opportunities.
- Low-Income Housing and Historic Credits: Structuring and compliance are critical to preserving credit value.
- State and Local Incentives: Property tax abatements, job credits and development grants vary widely by jurisdiction.
- Prevailing Wage and Apprenticeship Requirements: Certain credits now require compliance documentation to qualify for enhanced benefits.
Planning opportunity: Coordinating credit planning early in the development lifecycle often yields significantly better results than addressing incentives after construction begins.
RKL services that can help
- Identifying applicable federal and state credits early in project planning
- Assisting with Section 179D, energy credits and transferability analysis
- Coordinating with engineers and third-party study providers
- Advising on documentation and compliance requirements
- Structuring transactions to maximize credit utilization
SALT Planning, Nexus and Entity Structuring
As your company expands geographically, state and local tax exposure often becomes more complex than federal reporting.
Key considerations:
- Multi-State Nexus: Physical presence, economic nexus and project duration can create filing requirements.
- Apportionment of Revenue: Construction contracts may be sourced differently depending on the state.
- Pass-Through Entity (PTE) Taxes: Elective state-level taxes may provide federal deductibility benefits
- Composite Filings and Withholding: Required for multi-state owners and partners.
- Entity Structure Alignment: Proper use of LLCs, partnerships, and S corporations can impact both liability protection and tax efficiency.
Planning opportunity: A proactive SALT review can reduce compliance risk while identifying structural opportunities to improve overall effective tax rates.

Planning Should Be Ongoing, Not Reactive
In 2026’s environment of changing depreciation rules, evolving state conformity, and continued scrutiny of method and credit compliance, you’ll benefit most from integrated tax planning that aligns with your project lifecycle, capital strategy and growth goals.
Early coordination between your financial management team and tax advisor often results in stronger cash flow, reduced audit exposure and more predictable after-tax returns.
The complexity of today’s environment also reinforces the importance of working with experienced industry-focused advisors who understand how tax rules intersect with job costing, development timelines, financing structures and ownership goals.
