A year-end tax check starts with withholding and records

The IRS highlights income changes, quarterly payments and a simple document system as preparations for the 2027 filing season.

The Internal Revenue Service encouraged taxpayers on October 23 to review withholding, organize records and use official account tools before the 2027 filing season. The reminder addresses federal income tax planning throughout the year rather than announcing a new filing deadline.

Marriage, divorce, a birth or adoption, and a job change can affect withholding, filing status or eligibility for credits and deductions. The agency directs wage earners to its Tax Withholding Estimator and says a new Form W-4 should be submitted to an employer when an adjustment is needed.

Self-employed people, small-business owners and gig workers may need quarterly estimated payments when income is not subject to withholding. The IRS reminder does not set one payment amount for everyone; the appropriate amount depends on the taxpayer’s circumstances.

The agency’s Individual Online Account can be used for tasks such as viewing balances, payments, certain notices and records, reviewing payment plans and requesting an Identity Protection PIN. Its tools page also links to free preparation options and explanations of credits and filing status.

The IRS recommends an electronic or paper system for forms W-2 and 1099, digital-asset transaction records, the previous year’s returns, bank information, notices and documentation supporting claimed benefits. Keeping those items together can make preparation easier and help avoid overlooking relevant information.

The agency also warns against opening unexpected attachments or links in messages claiming to be from the IRS. Suspicious emails and texts can be reported to phishing@irs.gov. Official online tools should be reached directly rather than through an unverified request for personal information.
