Preparing Advisors Before Year-End Tax Planning

investor tips Oct 26, 2026

Year-end tax planning often becomes more productive when the right information reaches the right advisors before December.

For commercial property owners, that can mean looking beyond financial statements and tax returns. Property acquisitions, renovations, capital projects, and prior improvements may involve records that help advisors understand what actually happened at the property.

The investor question is simple: What should I have ready before I talk with my advisors about year-end planning?

Start With What Changed at the Property

A useful review begins with the property itself.

Think through the ownership activity that occurred during the year. Did you acquire a property? Complete a renovation? Replace or add major components? Finish tenant improvements? Place a new project in service?

These events can create questions that require more than a year-end accounting summary.

The IRS Cost Segregation Audit Technique Guide emphasizes that cost segregation is factually intensive and involves both tax law and engineering analysis. It also identifies documentation as an important part of a quality cost segregation study.

That makes the property story important.

Your CPA understands the broader tax picture. An engineering-based cost segregation professional can help document and analyze the property itself. Bringing those perspectives together gives everyone better information for the planning conversation.

Gather Records While They Are Accessible

One of the most practical things an owner can do is organize property records before they become difficult to locate.

Depending on the project, useful records may include:

• Purchase and closing documentation
• Construction drawings and specifications
• Contractor documentation
• Purchase orders and change orders
• Cost records
• Fixed asset records
• Information describing renovations or improvements

The ATG specifically notes that a quality study uses the best available documentation to classify assets and determine costs, and that contemporaneous documentation is the most reliable and trustworthy. For new construction, it discusses reviewing construction documents, plans, specifications, purchase orders, and change orders.

The lesson for investors is straightforward: good recordkeeping is not simply an administrative exercise. It can support better analysis later.

Give Advisors Context, Not Just Numbers

A spreadsheet can tell an advisor what something cost. It may not explain what was built, why it was installed, how a space is used, or what changed during a renovation.

That context can matter.

The ATG describes a quality study as one that explains its methodology, uses appropriate documentation, conducts interviews with appropriate parties, explains its legal analysis, and reconciles allocated costs to actual costs.

In other words, supporting an analysis involves more than assigning numbers to a list of assets.

When preparing for a planning conversation, consider whether your advisors have enough information to understand both the costs and the underlying property activity.

Coordinate Before Decisions Need to Be Finalized

Waiting until the last year-end meeting to introduce a major acquisition or completed renovation can limit the time available to review the facts.

Earlier coordination does not mean assuming that a particular tax strategy applies.

It means giving your CPA and other advisors time to ask questions, identify missing information, and determine what deserves further analysis.

That distinction matters because property classifications are not based simply on an asset's name. The ATG explains that cost segregation involves determining proper classifications and costs, and that some studies require specialized expertise because of the factual and technical nature of the analysis.

Make the Conversation More Useful

Before your year-end planning meeting, review the properties in your portfolio and ask:

• What did we acquire this year?
• What did we renovate or improve?
• What projects were completed or placed in service?
• Do we have the supporting property and cost records organized?
• Does our CPA know about the significant property activity?
• Is there anything that may require engineering-based analysis?

You do not need to arrive with every answer.

The goal is to arrive with enough information for your advisors to ask better questions.

Year-end planning becomes more useful when it starts with a clear picture of what happened at the property, supported by records that help the advisory team evaluate the facts.
