99 Days to Year-End: 2026 Tax Planning Checklist

With approximately 99 days left in 2026, (YIKES!) this is a practical time to assess your tax position before filing season begins. The final stretch of the year can offer opportunities to address changes that may affect your tax result, manage cash flow, and reduce the risk of an unexpected amount due.

Tax planning is often more effective before December 31 than after the year has ended. A change in income, a new source of side earnings, increased retirement savings, or a significant life event can all affect your tax picture. Reviewing those developments now can help make the upcoming filing process more manageable.

Year-end tax planning does not need to feel overwhelming. By focusing on a few key areas, you can gain a clearer view of where you stand for 2026 and identify steps that may be beneficial before the calendar turns.

Check Your Withholding and Estimated Tax Payments

Reviewing paycheck withholding and estimated tax payments is an important part of 2026 year-end tax planning. The amounts already paid toward your tax obligation should be considered alongside your current income and any changes that occurred during the year.

A job change, additional earnings, investment transactions, self-employment income, or major personal developments may change the tax you ultimately owe. When withholding or quarterly payments do not reflect those changes, an unexpected balance could arise when you file.

Looking at these figures before year-end gives you time to determine whether an adjustment is needed. Taking action now may help prevent unwelcome surprises during tax season.

Review Side Income and 1099 Activity

Income earned outside a traditional job has become increasingly common. Freelance projects, consulting work, online selling, rideshare services, and digital payment platforms can all create income that needs to be considered for tax reporting.

If you had side income in 2026, use the remaining months of the year to review your documentation. Keeping track of revenue, expenses, and possible tax obligations can help you stay organized and develop a better understanding of your filing responsibilities.

A year-end review of self-employment activity may also reveal eligible business deductions. It can also reduce the chance of avoidable complications once it is time to prepare your return.

Consider Increasing Retirement Contributions

Retirement accounts can support long-term savings goals while also playing a role in current-year tax planning. Before year-end, it may be worthwhile to review your contributions to eligible accounts.

Additional contributions may reduce taxable income while increasing the amount set aside for retirement. Taxpayers age 50 and older may have catch-up contribution options that allow for additional tax-advantaged savings before the year ends.

Recent legal changes have also created expanded contribution opportunities for certain people in their early 60s. That makes a year-end retirement review particularly relevant for individuals nearing retirement.

Assess Whether a Roth IRA Conversion Makes Sense

The end of the year can also be an appropriate time to consider whether a Roth IRA conversion supports your broader financial objectives. This strategy involves moving some funds from a traditional IRA into a Roth IRA.

A conversion generally adds taxable income in the year it takes place. In exchange, qualified withdrawals from the Roth account may be tax-free in the future.

For individuals in a lower-income year or those planning for future retirement distributions, it may be useful to evaluate the long-term effect of a Roth conversion before December 31. The potential tax impact should be reviewed in light of your individual circumstances.

Look at Education and Dependent Care Benefits

Families with children and taxpayers supporting college students should review available tax benefits before the year closes. Education and dependent care expenses may create opportunities that are important to identify while records are current.

If you or a dependent attends college, paying certain qualified education costs before year-end may help maximize available education-related tax credits, depending on your overall situation.

It is also important to review records for daycare, after-school care, summer day camps, and other qualifying care expenses paid so that you could work or look for work. Recent tax law changes expanded the Child and Dependent Care Credit beginning in 2026, making this a timely area to revisit before filing season.

Make the Most of HSA and FSA Accounts

Health Savings Accounts and Flexible Spending Accounts can provide meaningful tax advantages, yet they are easy to overlook until late in the year. A timely review can help you understand the opportunities still available.

Check applicable contribution limits, current account balances, and qualifying expenses before year-end. Depending on your circumstances, there may still be ways to use HSA and FSA tax benefits before the calendar year concludes.

Spending a few moments on these accounts now can help ensure you are taking full advantage of their tax-favored treatment.

Revisit Charitable Giving Plans

Charitable contributions remain a valuable year-end planning topic for many taxpayers. Giving decisions can have both personal significance and potential tax implications.

Under the One Big Beautiful Bill Act, taxpayers using the standard deduction may still qualify to deduct certain cash charitable gifts beginning with the 2026 tax year. That means charitable giving may deserve consideration even when itemizing deductions is not expected.

Taxpayers near the point at which itemizing could be beneficial may also want to consider whether combining charitable gifts into one tax year could improve the overall tax value of their giving plan.

Confirm RMDs and Update Beneficiary Designations

Retirement tax planning includes more than saving and contributing. In general, taxpayers age 73 and older must take required minimum distributions from certain retirement accounts each year.

Missing a required distribution or withdrawing too little can lead to penalties. Reviewing account balances and distribution requirements before the end of 2026 can help ensure this obligation is addressed on time.

This is also a useful time to check beneficiary designations for retirement accounts, life insurance policies, and other financial accounts. Marriage, divorce, births, deaths, and other family changes can leave prior designations out of date. Keeping these records current helps align the distribution of assets with your wishes.

Organize Documents Before Filing Season

Organizing tax records is among the simplest and most valuable year-end planning steps. Gathering information early can reduce stress and help make tax preparation more efficient.

Collect receipts, donation acknowledgments, bank statements, documentation for business expenses, and other relevant tax records while they are still easy to find. Early organization may also help uncover deductions or credits that could otherwise be overlooked.

As tax season approaches, locating missing paperwork and confirming key details can become more difficult. Taking time now to prepare your records can make a meaningful difference later.

The last months of the year move quickly, but there is still time to review valuable 2026 tax planning opportunities. A handful of proactive steps may improve your overall tax outlook and ease the pressure of preparing your return.
