Is It Too Late for 2026 Tax Planning After Thanksgiving?

Short answer: Some 2026 tax-planning windows have closed. Others may remain open into December, but time is short. Not all strategies are right or available for every client. Start with the client’s circumstances, then confirm timing and requirements.

Some planning deadlines have already passed

By the time Thanksgiving passes, the year-end tax bill may be on a client’s mind. But some strategies need to be considered well before December.

The current Q4 planning guide lists October deadlines for new cost-segregation projects, a November 15 deadline for a renewable-energy tax-credit opportunity, and November intake dates for new Step-Ladder Strategy clients. Those dates all fall BEFORE thanksgiving.

For example, The Step-Ladder Strategy has trusts that must be signed by December 31, but in general new clients need to be submitted by November 1 and engaged by November 15. Of course, a missed date doesn’t always mean the planning conversation has to wait until next year. But it does mean the next step should be a quick check of what is still available, with an acknowledgement that some strategies for this year are already too late to pursue.

2026 tax-planning opportunities that may still have time

There are several unique opportunities with December timing, especially if you’re an Accountant or an Advisor who utilizes a Virtual Family Office. These dates can refer to different steps, such as starting a review, initiating a strategy, or completing it, depending on specific cases.

This is key though: A December date does not necessarily mean there is time to wait until December to get started. Find out whether the deadline is for beginning a review, initiating the strategy, signing documents, or completing implementation.

These are just some examples, not a complete list. Eligibility, capacity, implementation time, costs, and client fit vary.

Start with the client’s tax situation

When time is short, it can be tempting to scan a strategy list and search for a match. A better starting point though is the client’s specific situation. Consider a closer review for clients who experienced a major change, such as:

• A large bonus, K-1, stock-option event, or other unusually high income
• A substantial increase in business profit
• A business or appreciated-asset sale
• A large capital gain or other liquidity event
• A significant charitable goal

Then clarify what has already happened and what decisions are still open. A strategy connected to a sale, for example, may have different requirements before and after the transaction. A year-end deadline does not automatically mean the opportunity is still available after the income or sale has occurred.

So with that in mind, here are 4 simple questions to guide a year-end review. If a client may have a meaningful planning need, use the first conversation to establish the basics:

1. What is the client’s projected 2026 income and tax exposure? Use the best current information available.
2. What major transactions have already happened, and what is still pending? Timing can affect what can be considered.
3. What can the client realistically complete before the deadline? Allow time for analysis, documentation, approvals, financing, and implementation.
4. Who needs to review the opportunity? Involve the appropriate specialist. This is where access to a VFO becomes paramount.

Accountants and Advisors don’t need to master every specialized strategy. They can identify a potential planning need, explain what they know about the client’s situation, and help the client take the next step with an appropriately qualified professional.

When no December tax strategy is a fit

A year-end tax review can still help even if no remaining opportunities suit the client. You can clarify their projected tax position, identify missing information, document decisions, and set a planning conversation for next year before the calendar becomes urgent again.

The goal is not to force a strategy into the final weeks of December. Instead, the idea is to give the client a clear answer about what can still be considered even if time is running out, and what has already passed…along with what can be done next.

Many Advisors and Accountants bring in a specialist from a VFO when a case calls for it.

Accountants do not need to become experts in every specialized strategy to help a client take the next step. When a situation may warrant deeper analysis, the Accountant can identify the issue, make an introduction to the appropriate specialist, and remain involved in the broader client conversation.

ERT’s Virtual Family Office gives Accountants access to these specialists who can help evaluate and coordinate advanced tax planning opportunities. The first step is a focused review of the client’s goals, timeline, and tax position, not a commitment to implement a strategy.

Frequently asked questions

Is it too late to reduce 2026 taxes after Thanksgiving?
Not always. Some deadlines have passed, but there are some opportunities with December timing. Whether a client can still pursue one depends on eligibility, availability, the specific deadline, and how much work remains.

What should an Accountant do first to tax plan after Thanksgiving?
Start with the client’s projected income, major transactions, goals, and timeline. Then confirm whether any relevant opportunity is still available and what steps must be completed before year-end.

Does a December 31 deadline mean the client can wait until December?
No. A year-end date may refer to the final signing or completion step. The client may need to start earlier to allow time for analysis, approvals, documentation, funding, or implementation.

What information should an Accountant gather for a year-end tax-planning review?
Start with the client’s best estimate of 2026 income, major transactions, expected tax liability, charitable goals, available cash, and any decisions that are still pending. The specialist reviewing a potential strategy may need additional details.

What if I don’t have a specialist to review a potential strategy?
You can identify the client’s situation and the question that needs to be answered, then make an introduction to a qualified professional. ERT’s Virtual Family Office gives Accountants a way to access specialists for a deeper review.
