This page describes a composite hypothetical. It is not a real client or a real result. The facts and numbers are assumptions for illustration.

The Scenario in Brief

A bakery owner orders new ovens in mid-December, expecting to claim a deduction on the return for the year. The equipment is delivered on December 28, but the electrician cannot complete the installation and hookup until January 6. The owner asks the advisor whether the deduction belongs in the current year or the next.

Assumptions Used

The Rule the Advisor Would Explain

For depreciation purposes, property is generally treated as placed in service when it is ready and available for its specifically assigned function. That is not the order date, the payment date, or necessarily the delivery date. For equipment that requires installation, the property is not ready and available for use until installation is complete and it can be operated. Section 179 and bonus depreciation depend on placed-in-service timing. Paying for the equipment in December does not by itself create a deduction for the year.

Applying the Rule to the Facts

In this scenario, the ovens were delivered but could not be used until January 6 after installation. The advisor would generally conclude that the ovens were placed in service in the following year, unless the facts support an earlier date. Documentation matters. The advisor would ask for the delivery receipt, the installation invoice and completion date, and any permits or inspection sign-offs that show when the equipment became ready for use.

Worked Arithmetic

Last week of Decemberup to 90,000 dollarstax reduction of about 28,800 dollars this year
January of next yearnonetax reduction of about 28,800 dollars next year if deducted then

The example shows a timing difference for the same asset and the same total deduction. If income in the next year is lower, the value of the deduction could differ. The comparison also depends on whether expensing is available and whether the owner wants to elect it. The figures are arithmetic on assumptions.

What the Owner Could Have Done

The advisor would discuss ways to reduce timing risk in future years. Owners planning a year-end purchase can order early, confirm the installation schedule with the vendor, and verify that the equipment will be operational before December 31. They can also confirm whether the equipment is in a category that requires more setup time. If timing cannot be met, the owner can consider other planning tools for the year, such as retirement plan contributions, but should not rely on a purchase that cannot be placed in service.

Scenario Variations Worth Considering

If the ovens had been ready to use on December 30 and the bakery had baked even a test batch, the placed-in-service date might be December. If the equipment did not require installation, delivery might be enough. If the equipment were delivered and installed but the bakery had not yet obtained a required permit, the date could be in question. Each fact affects the answer.

Risks and Limits

What This Scenario Teaches

Year-end deductions depend on facts that occur before year end. A purchase order and a payment are not enough. Planning early and keeping installation records makes the difference.

Questions to Bring to Your Advisor

  1. When will each asset be ready and available for use?
  2. What documents will show the date?
  3. What alternatives are there if installation slips into January?
  4. Should I plan purchases earlier in the year?

A Checklist for Year-End Purchases

An advisor working with this owner might suggest a short checklist for any purchase planned near year end. Confirm the delivery date in writing with the vendor. Ask whether installation, testing, or inspection is required before use, and how long each step takes. Line up the installer or electrician before the order is placed. Keep the delivery receipt, the installation completion notice, and any inspection record. Take dated photos of the equipment in operation. Record the first day of use in the fixed asset schedule. If any step is likely to slip past December 31, tell the advisor early so alternatives can be considered while there is still time.

Why Documentation Beats Memory

Placed-in-service disputes usually turn on records. A vendor invoice that shows a December delivery does not prove that the equipment was ready to use. An installation completion note, a dated photo, or a first-use production record can. Collect them at the time, since they are hard to reconstruct later.

Frequently Asked Questions

Does paying for equipment in December create a deduction for that year?

Not by itself. The property generally must be placed in service by year end.

Is this scenario based on a real bakery?

No. It is a composite hypothetical created for education.
