Tax Season Checklist: What You Need Before You File
Before filing, gather your W-2s (due Jan 31), 1099s, and deduction records; choose a filing status; decide standard vs itemized deductions; and decide whether to DIY or use a professional. Tax filing is due April 15 in 2026, with extensions to October 15. Missing documents are the #1 cause of filing delays.
Gather Your Income Documents
Start by collecting everything that reports your income: W-2s (employers must issue them by January 31), 1099-NEC for contract work, 1099-INT and 1099-DIV for investment income, 1099-B for stock sales, 1099-G for unemployment, and 1099-K for payment app or gig earnings. Missing a document is the most common cause of filing delays — wait until you have them all, then reconcile against your records.
Collect Deduction and Credit Records
Beyond income, gather records for deductions and credits: mortgage interest (Form 1098), student loan interest (Form 1098-E), tuition payments (Form 1098-T), charitable contribution receipts, medical expenses, child care invoices, and retirement contribution records. If you itemize, these add up quickly. If you're self-employed, organize business expense receipts and mileage logs.
Choose Your Filing Status
Your filing status — single, married filing jointly, married filing separately, head of household, or qualifying widow(er) — determines your brackets, standard deduction, and many credits. Choosing the right one can save thousands. Head of household requires you to pay more than half of household costs and have a qualifying dependent. Most married couples benefit from filing jointly; married separately rarely saves money.
Standard vs Itemized: Do the Math
Compare your total itemized deductions to the 2026 standard deduction: $15,000 single, $30,000 married filing jointly, $22,500 head of household (plus extra for age 65+ or blind). About 87% of taxpayers take the standard deduction. Itemizing only wins when mortgage interest, SALT (capped at $10,000), charitable gifts, and medical expenses over 7.5% of AGI exceed the standard amount.
DIY, Software, or a Professional?
Free File or commercial software handles straightforward returns — one W-2, standard deduction, no business income — in under an hour. A tax professional is worth the fee when you own a business, have rental properties, sold a home or investments, exercise stock options, or experienced a major life change. Whatever you choose, file by the April 15 deadline, or request an extension (also due April 15) to file by October 15. An extension to file is not an extension to pay.
Frequently Asked Questions
When is the tax filing deadline in 2026?
April 15, 2026. An automatic 6-month extension moves the filing deadline to October 15, but it extends only your time to file — any tax owed is still due April 15, and interest and penalties apply to late payments.
What happens if I miss a W-2 or 1099?
File once you have all your forms, or reconcile your records if a document is genuinely lost. The IRS matches returns against employer and bank filings, so omitting income can trigger a notice or audit. Ask your employer for a replacement W-2, and use Form 4852 to reconstruct income if needed.
Do I need to file if I made little income?
You may not be required to file if your income is below the filing threshold — about $14,600 for single filers under 65 in 2026. But you may still want to file to claim a refund of withheld taxes or refundable credits like the Earned Income Tax Credit.
Can I get my refund faster?
Yes — file electronically with direct deposit, and the IRS typically issues refunds within 21 days. Avoid paper returns and paper checks, which can add weeks. File early in the season to avoid the refund backlog that builds near the April deadline.
