Tax tips: what to gather and check before filing

By Refund Answers

Before you file, focus on three things: complete income records, the right filing status and dependents, and a review of the actual return—not just the refund estimate. The IRS says you are responsible for the information on your return even when someone else prepares it, and errors can delay processing. IRS common-error checklist

This checklist covers U.S. federal personal income-tax preparation, not state rules or individualized tax planning. Use forms and instructions for the tax year you are filing; don’t apply current-year figures to an older return.

1. Gather records before entering numbers

Make a list of every employer, income source and relevant expense, then match it to the documents you have. The IRS’s document guide includes:

• Identity and filing information: Social Security numbers or ITINs for everyone on the return, your current address, last year’s return and any IRS identity protection PIN (IP PIN).
• Income forms: W-2s from every employer; applicable 1099s for interest, dividends, unemployment, freelance work and retirement distributions; and SSA-1099 for Social Security benefits.
• Credit and deduction records: Childcare, tuition, charitable donations, retirement contributions, and mortgage or property-tax records where relevant.
• Marketplace insurance: Form 1095-A if you had Health Insurance Marketplace coverage.
• Side-work records: Income and expense records, payment-platform statements, mileage logs and estimated tax payments.

Don’t treat “no 1099” as “no taxable income.” The IRS requires reporting gig-work income even when no information return arrives or you were paid in cash. Compare your own records with the forms received. IRS gig economy guidance

If a document you expect is missing or appears wrong, resolve that question before submitting rather than guessing.

2. Recheck filing status and dependents

Don’t automatically carry last year’s answers forward, especially after marriage, separation, a death or changes in who you support.

Filing status affects filing requirements, the standard deduction, certain credits and tax. The IRS’s filing-status interview asks about marital status and household costs. Its separate dependent interview helps assess whom you may claim using relationship, support and income information.

Both tools are designed for people who were U.S. citizens or resident aliens for the entire tax year, with the same condition applying to a spouse if married. If that doesn’t describe your situation—or another person may claim the same dependent—get help before filing.

3. Check eligibility, not just receipts

Having an expense record doesn’t establish that you qualify for a tax benefit. Work through the software’s credit and deduction questions rather than skipping them or assuming last year’s result still applies.

A credit reduces tax; a deduction reduces income subject to tax. If you are eligible to choose between standard and itemized deductions, compare the options using qualifying expenses. Tax software can walk you through that comparison. Married people filing separately cannot take the standard deduction if their spouse itemizes. IRS credits and deductions guide

4. Review the completed return before signing

Use the IRS’s common-error checklist for this final pass:

• Names and Social Security numbers match each person’s Social Security card; ITINs and the address are correct.
• One correct filing status is selected, and dependent details are accurate.
• Income and withholding from every W-2 are included on one return.
• Deductions, credits and required schedules are complete.
• Any required IP PIN is entered.
• The return is signed and dated; both spouses sign and date a joint return.
• Any direct-deposit routing and account numbers are checked against bank records.
• If you owe tax, payment is arranged by the applicable payment deadline.
• A copy of the signed return and all schedules is saved.

E-filing can catch common errors and return a rejected submission for correction, but it does not replace your review. For a paper return, also check required attachments, mailing address and postage.

5. Know when to pause—and protect the deadline

Pause if you cannot explain a claimed credit, reconcile an income amount or settle a filing-status or dependent question. A qualified tax professional can help; eligible readers may also use free VITA or TCE preparation. Confirm that the site can handle your return, because available services vary.

If you need more time, request an extension by your applicable filing deadline. An extension to file does not extend the deadline to pay taxes owed. Estimate any unpaid tax and pay by the payment deadline. See the IRS’s extension instructions and filing and payment guidance for your situation.
