What Changed Financially This Year? Your Year-End Tax Planning Checklist

November 09, 2026

When people think about taxes, they often think about gathering documents, preparing returns, and finding out whether they owe money or will receive a refund.

But tax preparation and tax planning serve different purposes.

Tax preparation reports the financial activities that have already occurred. Tax planning evaluates those activities and identifies decisions that may still be made before the year ends.

One of the most useful questions you can ask yourself is simple:

What changed financially or personally during the year?

The answer may reveal tax issues or planning opportunities that deserve attention before December 31.

1. Did Your Employment or Income Change?

Changing jobs, receiving a substantial bonus, taking on consulting work, or working multiple jobs can affect your overall tax liability.

Your payroll withholding may have been based on circumstances that are no longer accurate.

For example, a married couple whose combined earnings increased significantly may need to evaluate whether enough federal income tax has been withheld.

The IRS recommends reviewing withholding following major income and life changes. Its Tax Withholding Estimator can help eligible taxpayers evaluate their withholding based on current circumstances.

The objective isn't necessarily to eliminate any balance due. It's to understand the expected liability and determine whether adjustments are appropriate.

2. Did You Start or Expand a Business?

Starting a business, becoming self-employed, or experiencing a substantial increase in business profits can create new tax responsibilities.

Business owners should review year-to-date profit, significant purchases, employee compensation, retirement-plan considerations, and estimated-tax payments.

For an S corporation owner, compensation and shareholder distributions may also require review.

A profitable business doesn't automatically mean the owner has paid sufficient income taxes.

Planning should consider the business's structure, accounting records, and the owner's broader tax situation—not simply whether the business has money in its bank account.

3. Did You Purchase or Improve Rental Property?

Rental properties introduce additional tax considerations.

Property owners need to distinguish ordinary repairs from capital improvements, maintain depreciation records, and properly track rental income and expenses.

Purchasing a property also raises questions about when it was placed in service, how its cost is allocated, and whether particular expenses are currently deductible.

A review before tax season can help identify missing documentation and questions that should be resolved while records are readily available.

4. Did Your Retirement Situation Change?

Retirement-related decisions can have significant income-tax consequences.

Beginning retirement distributions, receiving pension payments, taking required minimum distributions, or considering a Roth conversion may affect taxable income and other tax calculations.

For example, converting funds from a traditional IRA to a Roth IRA generally creates taxable income to the extent the converted funds have not already been taxed.

Roth conversions made after 2017 cannot be reversed through recharacterization.

This makes advance analysis particularly important. A decision that may be beneficial over the long term can still generate a substantial current-year tax obligation.

The IRS explains these rules in its retirement-plan IRA guidance.

The appropriate decision depends on factors such as current and expected future income, available cash to pay the tax, and the taxpayer's broader financial situation.

5. Did Your Family Circumstances Change?

Marriage, divorce, the birth or adoption of a child, and the death of a spouse can affect tax filing status, withholding, credits, and deductions.

For many taxpayers, filing status is determined by marital status on the last day of the tax year, although special rules and exceptions may apply.

A surviving spouse, for example, may face different filing-status and income-tax considerations in subsequent years.

The IRS discusses these situations in its guidance on major life events and filing.

These changes should be discussed before assuming the next return will resemble the previous one.

What Should You Bring to a Tax Planning Meeting?

A useful planning conversation starts with reliable information.

Gather your most recently filed tax return, current pay statements, year-to-date business information, rental-property records, estimated-tax payments, retirement-account distribution details, and documentation of significant personal or financial changes.

Also prepare a list of decisions you're considering before year-end.

This last item is especially important. Planning can be more valuable when an important financial decision has not yet been finalized.

Make Planning an Ongoing Process

Not every financial change creates a tax-saving opportunity, and some strategies have limitations, deadlines, or unintended consequences.

The goal is to evaluate your circumstances, understand available options, and make informed decisions rather than relying on assumptions.
