Materials Bought for a Job That Will Not Finish This Year
The materials are real. Which job used them, what is still on hand, and how the costs are treated at year-end are separate questions.
A load bought in November for a job that will still be open in January needs a clear record. The purchase date and the job’s finish date alone do not settle the year of the tax deduction. Start by showing what was used, what is waiting, and which job each item belongs to.
This checklist focuses on materials on hand. For the broader closing process, use the year-end books cleanup checklist.
Separate the Materials Into Three Groups
Used on a job this year
Identify the job that actually used the materials. Keep the supplier invoice and the supporting delivery or usage record together. For management reporting, those materials should be traceable to that job, whether it is finished or still running.
That job assignment is not an instruction to expense the amount immediately for financial-statement or tax purposes. The appropriate accounting treatment still needs to follow the business’s method and applicable rules.
Bought for a job, not yet used
Materials sitting in the shop or on site for a specific job should remain identifiable with that job. Record their quantity, location, cost, and unused status. Delivery to a site does not necessarily mean the materials have been installed or consumed.
Keep reserved materials distinguishable from materials already used. Do not charge them to an unrelated completed job simply to clear a general materials account.
Bought with no job attached
Stock, leftovers, and materials bought because the price was good may have no next job yet. Keep them on an unassigned materials schedule until their destination is known. Record where they are and reconcile the schedule to the books; a loose note is not a substitute for proper accounting records.
If leftovers came from a completed job, document the quantity and cost being returned to stock. Have the bookkeeper review any transfer so the same materials are not counted twice.
Build the Year-End Materials List
For a calendar-year business, count and document materials at the December 31 cutoff. Use the business’s actual year-end if it follows a different fiscal year. Start with fourth-quarter purchases, then include older stock still on hand.
For each item or identifiable batch, record:
- Supplier, invoice number, purchase date, and delivery date.
- Description, quantity, unit cost, and total cost supported by the invoice.
- Quantity used and the job that used it.
- Quantity still on hand and its physical location.
- Intended job, or an explicit unassigned-stock designation.
- Returns, credits, transfers, damage, or shortages needing review.
- Who checked the count and when.
Reconcile the list with supplier bills, credits, and the materials accounts. The vendor-bill review guide covers checking the invoice itself. Do not post a second expense merely because an item appears on this list.
Keep Unused Materials Visible on Open Jobs
A job manager should be able to see both materials already used and materials reserved for the remaining work. Label those figures clearly so a reserved-materials list is not mistaken for installed cost or an additional purchase requirement.
If a job-cost report already includes the purchase, reconcile that entry with the unused-materials schedule before making an adjustment. Avoid counting the same invoice once as a posted cost and again as a new cost to finish. The in-progress job-costing guide covers the broader forecast.
What This List Does Not Decide
Sorting the materials does not automatically create a deduction or defer one. The IRS explanation of materials and supplies distinguishes non-incidental supplies from other property and notes that capitalization rules can apply.
IRS Publication 538 explains accounting methods and inventory treatment, including alternatives available to qualifying small businesses. Eligibility and the method actually used matter. Construction-contract rules can also affect the final treatment, so ask the preparer to review the facts before making a year-end tax adjustment.
The useful handoff is a supported list of quantities, costs, locations, job assignments, and usage dates. It gives the bookkeeper and tax preparer facts to work with instead of a guessed balance.
How KDM Accounting Services Inc Can Help
KDM helps Florida contractors reconcile materials records, identify job assignments, and separate used materials from stock still waiting. We can review the list alongside the books and flag items that need tax-treatment review.
Used materials should be traceable to the job that used them. Reserved materials should remain identifiable with their intended job. Unassigned stock should stay visible without being forced onto an unrelated job.

Frequently Asked Questions
Does buying materials in December guarantee a deduction that year?
No. The purchase date alone does not settle the tax treatment. The accounting method, nature of the materials, and applicable inventory, capitalization, and construction-contract rules need review.
Are materials delivered to a job site automatically used?
No. Record their location and whether they remain unused, have been installed, or have been consumed. Keep reserved materials distinguishable from materials already used.
Where should materials with no assigned job go?
Keep them on an unassigned materials schedule reconciled to the books. Record their quantity, cost, and location rather than assigning them to an unrelated job.
What should the year-end materials list include?
Include supplier invoices, quantities and costs, delivery and usage dates, locations, job assignments, unused balances, and any returns, credits, transfers, damage, or shortages needing review.
Should unused materials be moved onto a finished job to clear the account?
No. Preserve the actual job assignment and unused status. Reconcile the materials schedule to existing entries and have the bookkeeper review adjustments so costs are not counted twice.
