In this article, we will discuss:

Key tax season deadlines and refund statistics Costco Wholesale employees should know.
Steps to reduce tax-related identity theft and common filing errors.
Retirement account contribution limits and planning opportunities for 2026.

With tax forms arriving in mailboxes and inboxes, tax season is officially underway for many Costco Wholesale employees. Depending on whether you expect a refund or anticipate owing taxes, filing your 2025 return can feel either rewarding or stressful. Starting early may help streamline the process and potentially limit last-minute pressure.

Statistics from the Internal Revenue Service show that the average refund issued during the 2024 filing season was $3,052 . For many individuals, receiving a refund can provide additional cash flow flexibility during the year.

The filing deadline for most individuals’ 2025 federal income tax returns is April 15, 2026 . If you request an extension by that date, you will have until October 15, 2026 , to file your return. Taxes owed, however, are still due by April 15, 2026. An extension allows additional time to submit paperwork, not additional time to remit payment. Taxpayers affected by federally declared disasters may qualify for deadline relief in certain situations.

There are several additional reasons to begin preparing your taxes early.

1. Take Precautions Against Identity Theft

Submitting a tax return early may lower the chance of tax-related identity theft. In these situations, criminals attempt to file fraudulent returns to claim refunds before legitimate filers submit their information. Filing promptly can limit the window for this type of activity.

If you believe your tax account may have been compromised, you should still file a valid return and pay any taxes due. In some cases, the IRS may ask for a paper return along with Form 14039, Identity Theft Affidavit . The IRS generally communicates with taxpayers through mailed notices rather than unsolicited emails, text messages, or social media messages.

2. Correct Errors and Make Adjustments

If you are waiting for tax documents from an employer, financial institution, or other source, it may be helpful to check whether electronic versions are already available. Accessing documentation earlier allows more time to review information and address potential inaccuracies.

Common tax filing mistakes include mathematical errors, missing income, overlooked credits, and incorrect reporting of investment transactions.

For example, Form 1099-B reports proceeds from investment sales used to calculate capital gains and losses. If total capital losses exceed gains, up to $3,000 may be deducted against ordinary income ( $1,500 if married filing separately ). Unused losses may be carried forward to future tax years.

3. Evaluate Planning Opportunities for 2026 and Beyond

The start of the year is often a practical time to review tax-related decisions that may affect upcoming filings.

You may consider adjusting tax withholding through your payroll department if your current withholding does not match your anticipated tax situation. Early planning may also help clarify contribution decisions for tax-advantaged accounts before the April 15, 2026 deadline.

IRA Contributions

For the 2025 tax year , the contribution limit for both traditional and Roth IRAs is $7,000 , with a higher limit of $8,000 for individuals age 50 or older. For 2026 , the limit increases to $7,500 , with a catch-up amount bringing the total to $8,600 for eligible individuals age 50 and older.

Traditional IRA contributions may lower taxable income for individuals who meet eligibility requirements. A nonworking spouse may also contribute to an IRA if the couple files jointly and has sufficient earned income.

HSA Contributions

For 2025 , Health Savings Account contribution limits are $4,300 for self-only coverage and $8,550 for family coverage, with an additional $1,000 catch-up contribution for individuals age 55 and older.

For 2026 , limits increase to $4,400 for self-only coverage and $8,750 for family coverage. Contributions for the 2025 tax year may generally be made until April 15, 2026.

SEP IRAs and Other Plans

Independent contractors and freelancers—including Costco Wholesale employees with consulting or side income—may establish a SEP IRA . For 2025 , contributions are limited to the lesser of $70,000 or 25% of eligible compensation . In 2026 , the maximum contribution increases to $72,000 .

Other retirement plan options for self-employed individuals include SIMPLE IRAs, Solo 401(k) plans, and pooled employer plans (PEPs).

4. Reduce Last-Minute Surprises

Waiting until the final days of the filing season can add unnecessary stress, particularly if taxes are owed. Filing an extension does not postpone payment obligations, and outstanding balances may lead to interest and penalties.

This may be especially relevant for individuals with self-employment or consulting income, who are typically required to make quarterly estimated tax payments. If estimated payments were missed, additional preparation may be required before filing.

5. Finish Early and Stay Organized

Tax preparation is often considered one of the year’s more time-intensive financial responsibilities. Beginning early and maintaining organized records throughout the year can make the process more manageable. Digital storage, consistent documentation practices, and organized filing systems can simplify future tax seasons.

Completing a return early may also provide a clearer view of your overall financial position, which can support broader retirement and income planning discussions.

Organizing Beyond Tax Season

Tax filing is only one element of a broader retirement strategy. Decisions related to IRA contributions, SEP IRAs, HSAs, and other retirement accounts can influence long-term financial outcomes.
