Deduction Stacking – A Strategic Tax Planning Approach

Deduction stacking is a tax planning strategy that allows high-income individuals to optimize deductions by concentrating multiple years’ worth of expenses into a single tax year. By strategically timing deductible expenses, taxpayers can maximize itemized deductions in high-deduction years while benefiting from the standard deduction in lower-deduction years. This approach is particularly effective for those without mortgage interest deductions but who make significant charitable contributions.

Understanding Deduction Categories

The IRS allows for four primary deduction categories that reduce taxable income:

• Medical expenses exceeding 7.5% of adjusted gross income.
• State and local taxes (SALT), including income, sales, and property taxes, capped at $10,000.
• Mortgage interest on primary and secondary residences, subject to loan origination limits.
• Charitable contributions, subject to applicable income thresholds.

How Deduction Stacking Works

Rather than taking similar deductions annually, deduction stacking concentrates multiple years of deductions into a single tax year to exceed the standard deduction threshold. Common strategies include:

• Bunching charitable contributions into one tax year instead of spreading them out.
• Prepaying state and local taxes to fully utilize the $10,000 deduction cap.
• Timing medical expenses to exceed the income-based threshold in a single year.

Key Takeaways:

• Deduction stacking is most effective for those who regularly contribute to charities but do not have mortgage interest deductions.
• The strategy helps exceed the standard deduction threshold, increasing tax-free income.
• Prepaying property taxes and strategically timing expenses can enhance overall deductions.
• Proper planning can yield an additional $15,000–$25,000 in tax-free income.

By leveraging deduction stacking, taxpayers can create a more tax-efficient strategy, ensuring they maximize available deductions while maintaining compliance with IRS regulations.
