Financial Horizons: Insights for Building Wealth and Securing Your Legacy
Retirement Contributions Are One of the Last Great Levers of the Year
By Dr. Jose G. Cardenas | Chief Tax Strategist, The C & R Group, LLC
By November, many year-end tax decisions are already becoming harder to change.
Income has mostly been earned.
Bonuses may already be scheduled.
Investment gains may already exist.
Major business transactions may be underway.
But one area can still give many taxpayers meaningful planning flexibility:
retirement contributions.
A retirement contribution can do more than build future wealth.
Depending on the account and the taxpayer’s circumstances, it may also:
reduce current taxable income,
improve long-term tax diversification,
help manage cash flow,
and shift more money from current consumption into future financial security.
That is why retirement planning belongs in the year-end tax conversation.
Retirement contributions are not just investment decisions. They are tax-timing decisions too.
Start With the Workplace Plan
For employees, the first place to look is usually the employer-sponsored retirement plan.
For 2026, the employee elective-deferral limit for 401(k), 403(b), governmental 457(b), and the federal Thrift Savings Plan is $24,500. For participants age 50 or older, the general catch-up amount is $8,000. Employees who are age 60, 61, 62, or 63 during 2026 may qualify for a higher catch-up limit of $11,250 under applicable plan rules.
That means a worker who has not yet reached the annual limit may still have room to increase contributions through the final pay periods of the year.
But timing matters.
Employee salary deferrals generally must be made through payroll during the year. You cannot usually wait until tax preparation season and retroactively decide that part of a December paycheck should have gone into the 401(k).
That makes November a critical planning window.
If you still have several paychecks left, ask:
How much have I contributed so far?
How much contribution room remains?
Can my remaining paychecks support an increased deferral?
And most importantly:
Does increasing the contribution make sense for my cash flow?
Do not max out an account if doing so leaves the household unable to pay normal expenses or fund the tax reserve.
Traditional Contributions Can Affect Today’s Tax Picture
Traditional salary deferrals generally reduce current taxable wages for federal income-tax purposes, although payroll-tax treatment and specific plan rules still apply.
That can make traditional contributions especially relevant for taxpayers having a high-income year.
Suppose an employee has contributed only $14,500 to a 401(k) by early November.
The 2026 elective-deferral limit is $24,500.
That potentially leaves another:
$10,000
of employee contribution room.
If the employee’s remaining compensation and plan rules allow it, increasing the traditional 401(k) contribution may reduce current taxable income while increasing retirement savings.
That does not mean traditional is always better than Roth.
It means current-year tax impact belongs in the decision.
Roth Contributions Solve a Different Problem
Roth contributions generally do not reduce current taxable income.
The contribution is made with after-tax money.
But qualified Roth distributions can be tax-free later.
So the decision between traditional and Roth should not simply be:
“Which one gives me the biggest deduction today?”
The better question is:
“Do I want the tax benefit now, or am I willing to pay tax today in exchange for potentially tax-free qualified income later?”
For many households, the answer may even be a combination.
Part traditional.
Part Roth.
The right mix depends on current income, future retirement expectations, pension income, Social Security, required minimum distributions, other assets, and the household’s long-term tax strategy.
We will go deeper into that question later this week.
IRAs Still Offer Another Planning Opportunity
For 2026, the combined contribution limit across traditional and Roth IRAs is $7,500, or $8,600 for taxpayers age 50 or older because the IRA catch-up amount is $1,100. Contributions also cannot exceed taxable compensation.
Traditional IRA contributions may be deductible depending on income and whether the taxpayer or spouse is covered by a workplace retirement plan.
Roth IRA contributions are not deductible, and income limits can restrict eligibility.
That means an IRA can be useful, but the tax treatment needs to be checked before assuming the contribution will reduce current taxes.
One important difference from salary deferrals is timing.
IRA contributions for a tax year can generally be made by the tax-return due date, excluding extensions, rather than necessarily by December 31.
So an IRA may provide more flexibility after year-end than an employee 401(k) deferral.
But that is not a reason to ignore it now.
Knowing your likely contribution strategy before year-end helps with cash planning.
Business Owners May Have Even More Leverage
Business owners can have additional retirement-plan options, including:
Solo 401(k)s,
SEP IRAs,
SIMPLE IRAs,
and other qualified plans.
For 2026, the overall defined-contribution limit is generally $72,000, before certain catch-up contributions, subject to plan rules and compensation limits. SEP contributions can also reach up to $72,000 for 2026, depending on eligible compensation and the applicable contribution formula.
A one-participant 401(k), commonly called a Solo 401(k), allows an eligible owner to participate in two capacities:
as the employee making elective deferrals,
and as the employer making employer contributions.
The IRS specifically notes this dual role for one-participant 401(k) plans.
That flexibility can make retirement planning one of the most powerful remaining year-end tools for a profitable small business.
But plan deadlines, plan documents, employee eligibility, contribution formulas, and business structure matter.
The right question is not:
“What account lets me deduct the most?”
It is:
“Which retirement plan actually fits the business, the employees, the cash flow, and the owner’s long-term goals?”
A Quick Example
Consider David and Jennifer.
David owns a profitable consulting business.
Jennifer earns W-2 wages.
By November, their projected household income is significantly higher than expected.
Jennifer has contributed:
$15,000
to her 401(k).
She still has contribution room under the 2026 limit.
David has also had a strong business year but has not yet completed the retirement-plan contribution review for his company.
Instead of chasing last-minute purchases just to generate deductions, they review retirement first.
Jennifer increases her remaining traditional 401(k) payroll deferrals.
David reviews the business retirement plan with his tax and retirement-plan professionals and determines what employer contribution may be appropriate under the plan.
They also review IRA eligibility.
The result is not simply:
“Lower the tax bill.”
They have redirected more money toward retirement.
Improved the household’s tax planning.
And avoided buying something unnecessary simply to create a deduction.
That is a much stronger use of year-end planning.
Retirement Contributions Still Have to Fit the Cash Plan
This is where discipline matters.
A retirement contribution may reduce current taxable income.
But once money enters a retirement account, it generally becomes less liquid.
That means you should not drain the business operating account or household emergency reserve simply to maximize a tax deduction.
Before increasing retirement contributions, ask:
Do we have enough cash for normal expenses?
Is the tax reserve funded?
Does the business have enough Q1 operating cash?
Are major debt obligations covered?
Will we need this money in the near term?
Tax planning should strengthen the financial plan.
Not starve it.
Your Five Year-End Retirement Questions
Before December 31, review:
How much have you already contributed for 2026?
How much contribution room remains under the applicable plan?
Should the next dollar go traditional, Roth, or somewhere else?
Does the contribution improve the tax picture without damaging cash flow?
Are there business-owner or IRA opportunities that should be coordinated before year-end?
That is enough to begin a meaningful retirement-tax review.
Final Thought
November is not the time to assume retirement planning is finished for the year.
For many taxpayers, it is one of the last meaningful planning opportunities still available.
You may still be able to:
increase workplace-plan contributions,
review traditional versus Roth,
coordinate an IRA contribution,
or evaluate a business retirement-plan contribution.
The key is not simply to contribute more.
The key is to make the contribution fit the tax plan and the long-term financial strategy.
A retirement contribution is strongest when it does three jobs at once: builds future wealth, supports today’s tax strategy, and preserves financial flexibility.
That is why retirement contributions remain one of the last great year-end levers.
