Bunching Your Deductions Can Provide Big Tax Benefits

If your tax deductions typically fall short of itemizing your deductions, or even if you can itemize, but only marginally, you may benefit from using the “bunching” strategy.

The tax code allows most taxpayers to utilize the standard deduction or itemize their deductions if that provides a more significant benefit. As a rule, most taxpayers wait until tax time to add up their eligible expenses and then use the higher standard deduction or their itemized deductions.

If you want to be more proactive, you can time the payments of tax-deductible items to maximize your itemized deductions in one year and take the standard deduction in the next.

Most itemized deductions include medical expenses, property taxes, state and local income (or sales) taxes, home mortgage and investment interest, charitable deductions, and casualty losses. The “bunching strategy” is more commonly associated with medical expenses, tax payments, and charitable deductions, although there are circumstances in which the other deductions might come into play. There are many opportunities to bunch deductions, and the following are examples of the bunching strategies most commonly used:

  • Medical Expenses – You contract with a dentist for your child’s braces. The dentist may offer you an up-front, lump sum payment or a payment plan. By making the lump sum payment, the entire cost is credited in the year paid, thereby dramatically increasing your medical expenses for that year. If you do not have the cash available for the up-front payment, you can pay by credit card, which is treated as a lump-sum payment for tax purposes. If you use a credit card, you must realize that the credit card interest is not deductible, and you need to determine if incurring the interest is worth the increased tax deduction. Another critical issue with medical deductions is that only the amount of the total medical expenses that exceed 7.5% of your adjusted gross income (AGI) is deductible. So, there is no tax benefit in bunching medical deductions unless the costs exceed this limitation. If the current year is an abnormally high-income year, consider putting off making medical expense payments until the following year when the 7.5% threshold is less.

  • Taxes – Property taxes on real estate are generally billed annually at mid-year, and most locales allow property owners to make semi-annual or quarterly payments. Thus, you have the option of paying it all at once or paying in installments. This provides the opportunity to bunch the tax payments by paying one semi-annual installment or two quarterly installments and a full year’s tax liability in one year and only paying one semi-annual installment or two quarterly installments in the other year. In doing so, you can deduct 1-½ years’ taxes in one year and 50% of a year’s taxes in the other. If you are thinking of making property tax payments late as a way to accomplish bunching, you should be cautious. The late payment penalty will probably wipe out any potential tax savings. This strategy won’t work if your mortgage payments include real property taxes that the lender holds until the taxes are due, as you can only deduct the tax payments that the lender makes on your behalf during the tax year. If you reside in a state with state income tax, the state income tax paid or withheld during the year is deductible as a federal itemized deduction. So, for instance, if you are paying state estimated tax in quarterly installments, the fourth-quarter estimate is generally due in January of the subsequent year. This allows you to either make that payment before December 31st and deduct the amount on the current year’s return or pay it in January before the January due date and use it as a deduction in the subsequent year. A few words of caution about the itemized deduction for taxes! Taxes are only deductible for regular tax purposes. So, to the extent you are taxed by the AMT (alternative minimum tax), you derive no benefits from the itemized deduction for taxes. Also, through 2025, you can deduct the maximum amount per year on your federal return for state and local taxes (property taxes and state income or sales taxes) is $10,000 ($5,000 if using the married separate filing status).

  • Charitable Contributions – Charitable contributions are an excellent fit for “bunching” because they are entirely payable at the taxpayer’s discretion. For example, suppose you usually tithe at your church. You could make your regular contributions during the year and then prepay the following year’s tithing in a lump sum in December of the current year, thereby doubling up on the church contribution one year and having no charitable deduction for a church in the other year. Typically, charities are very active with their solicitations during the holiday season, allowing you to make the contributions at the end of the current year or wait a short time and make them after the end of the year. Be sure you get a receipt or acknowledgment letter from the organization that clearly shows the year the contribution was made.
