Separate project milestones
Signing a purchase agreement, receiving keys, paying a contractor, and opening for business may happen on different dates. The depreciation analysis requires facts about readiness and availability for the intended use. Keep those facts rather than choosing the most convenient calendar date.
A property undergoing substantial work may need different analysis from a finished facility awaiting routine occupancy. Equipment and building components can also have different installation dates.
A clearly hypothetical timeline
An owner purchases premises in November, completes required electrical work in January, and begins production in February. The tax preparer needs the actual condition and availability during each period. The November purchase date alone does not answer when depreciation starts.
Save inspection approvals, utility activation, contractor completion records, photographs, and equipment commissioning reports. Ask the advisor which facts are decisive for the intended business use.
Maintain one milestone schedule
List each significant asset or project, purchase date, completion date, readiness evidence, and proposed placed-in-service date. Reconcile the schedule to invoices and the fixed-asset register.
Provide it before the year-end return is prepared. Current depreciation rules can depend on dates and other eligibility requirements, so inaccurate milestones can distort both timing and classification. A documented timeline is more useful than a bank statement showing when the deposit cleared.
Document each intended use separately
A property can be acquired in phases, with one area ready while another remains under construction. Ask the preparer how the facts affect the relevant assets and records. Do not force every asset into the same date simply because the purchase closed once. Machinery, tenant work, and later additions may have their own installation and readiness evidence.
Business plans can change during construction. A building purchased for storage may be redesigned for manufacturing, or a planned opening may be delayed by required permits. Preserve the sequence and the intended use at each stage. The advisor needs to understand what the taxpayer was preparing the asset to do. An occupancy certificate can be useful evidence but may not answer every tax question alone.
Consider a hypothetical facility where office space is ready in December but production machinery is commissioned in March. A single invoice or building deed cannot establish the readiness of every asset. Have operations staff prepare a short factual timeline and connect it to inspection records, commissioning reports, and photographs. The tax conclusion should follow those facts.
At year-end, ask whether any paid amounts relate to assets not yet available for use. Reconcile construction-in-progress records to the asset register and avoid depreciating deposits as if they were completed equipment. If work remains incomplete, record the expected milestone and follow up in the next period. Accurate cutoff is part of sound accounting as well as tax planning.
After the return is filed, preserve the evidence supporting the final dates and any changes from the initial forecast. If an asset is later moved or its use changes, retain those facts too. The record should explain what was ready, for which intended function, and when. That is more durable than a date selected from the purchase contract without examining the condition of the property.
Additional decision checks
Use evidence from people who know the project. A facilities manager can explain when systems operated, while a contractor can document completion and an inspector can describe approvals. Ask each person for facts within their knowledge rather than a tax conclusion. If evidence conflicts, preserve the conflict and obtain the advisor’s analysis. For illustration, a contractor may regard work as substantially complete while a necessary system remains unavailable for the intended business use. The owner should understand the actual condition at the relevant date. Record later changes separately instead of replacing the original timeline. A complete chronology helps the preparer make a defensible decision and prevents a convenient date from becoming an unsupported assumption copied into future returns.
Use the final timeline during return review and confirm that the preparer received updates after the initial forecast. A completed workpaper should reflect actual readiness evidence, not an uncorrected construction estimate.
