Tax document checklist: what to gather

By Tom, CPA · Updated October 27, 2026

Part of: Easy Tax Strategies

TL;DR: Collect income forms (W-2, 1099s, 1099-B, 1099-R, SSA-1099, 1095-A), deduction and credit records (1098, 1098-T, 1098-E, charity receipts, HSA forms), account details, last year's return and IDs. Most forms arrive by January 31; brokerage 1099s often come mid-February or later. Store everything in one digital folder.

Educational only, not tax, legal, or investment advice. Examples are illustrations, not predictions. Rules and limits change; verify current figures and talk to a qualified professional about your situation.

Doing your taxes is 20% math and 80% finding the piece of paper that has the math on it. Somewhere in your house there is a 1099-INT for $14 of interest, and it will not reveal itself until April 14 at 11 PM. This checklist is how you win that game in January.

It covers 2026 returns filed in 2027. Check off what applies, ignore what doesn't, and you'll be ready whether you use software, a volunteer or a preparer. Based on the IRS "gather your documents" guidance and form instructions, as of October 2026. More quick wins in easy tax strategies.

CPA Warning Label: The IRS gets a copy of nearly every 1099 you get; a forgotten one usually turns into an automated notice with interest a year later.

Income forms

Work

• W-2 from every employer, including the one you left in March. Due to you by January 31.
• 1099-NEC for freelance or contract work. For 2026 payments, payers generally send one if they paid you $2,000 or more, up from $600. You still report all income.
• 1099-K from payment apps and marketplaces, if you met the reporting threshold.
• Your own records of business income and expenses for Schedule C.

Money and investments

• 1099-INT (interest), 1099-DIV (dividends), 1099-B (sales, with cost basis). Brokerages often issue consolidated 1099s in mid-February and may send corrections.
• 1099-R for IRA, 401(k) and pension distributions, including Roth conversions and rollovers.
• Schedule K-1 from partnerships, S corporations or trusts. Often late, sometimes March or beyond.
• 1099-DA or other statements for digital asset sales, if any.

Government and other

• SSA-1099 for Social Security benefits.
• 1099-G for unemployment and state tax refunds.
• 1095-A if you had marketplace coverage. You need it to reconcile the premium tax credit on Form 8962.
• Rental records: rent received, expenses, mileage log and depreciation schedule.
• Alimony for divorces finalized before 2019, and gambling W-2G forms.

Deduction records

• 1098 mortgage interest statement, plus property tax bills if not on the 1098.
• State and local taxes paid: state estimated payments and the date paid. The 2026 SALT deduction cap is $40,400, reduced at higher incomes.
• Charitable giving: written acknowledgments for any gift of $250 or more, and receipts for smaller cash gifts. From 2026, non-itemizers can deduct up to $1,000 ($2,000 joint) of cash gifts to qualifying charities, so keep receipts even if you take the standard deduction.
• 1098-T tuition statement and receipts for books and required fees, for education credits.
• 1098-E student loan interest (deduction up to $2,500).
• HSA: Form 5498-SA (contributions) and 1099-SA (withdrawals), plus medical receipts.
• Child and dependent care: provider name, address, tax ID and amounts paid.
• New for 2025 to 2028: records supporting qualified tips, qualified overtime pay, or interest on a loan for a new US-assembled personal vehicle (with VIN), if you plan to claim those deductions.
• Estimated tax payments: dates and amounts for all four federal quarters.

Accounts

• Social Security numbers or ITINs for you, your spouse and dependents, and dates of birth.
• Bank routing and account numbers for direct deposit or debit.
• IRA contribution records (Form 5498 arrives in May, after the deadline, so use your own records).
• Identity Protection PIN, if the IRS issued one. It changes every year.
• Driver's license for states that ask for it to fight identity theft.

Prior year

• Last year's full return. You need prior-year AGI or your self-select PIN to e-sign. First-time filers use $0.
• Carryovers: capital loss carryover (up to $3,000 deductible per year, the rest carries forward), suspended passive losses, charitable carryovers, and nondeductible IRA basis on Form 8606. Missing these costs real money.
• Depreciation schedules for rentals and business assets.
• Overpayment applied to this year's tax from last year's refund.

Lost last year's return? Your IRS online account shows prior-year AGI and transcripts.

Life-event extras

Big life changes add paperwork. If any of these happened in 2026, add the matching items:

• Sold a home: closing statement, purchase records and receipts for improvements, plus Form 1099-S if issued. The home sale exclusion may cover the gain, but you need basis to prove it.
• Bought a home: closing statement (points and prepaid property tax can be deductible).
• Married, divorced or widowed: the date, a copy of the decree, and any name change with Social Security.
• Had or adopted a child: Social Security number for the child (needed for the child tax credit), and adoption expense records.
• Moved states: dates of the move and wages earned in each state, for part-year returns.
• Started a business or rental: start-up costs, asset purchase receipts and the date the property was placed in service.
• Inherited assets: date-of-death values from the executor, which set your stepped-up basis.

Digital folder

Create one folder per tax year, for example "Taxes 2026," with these subfolders: Income, Deductions, Accounts, Prior Year and Filed. Each January:

1. Turn on paperless tax forms at every bank and brokerage, and set a calendar reminder for February 15 to download them.
2. Scan paper forms the day they arrive.
3. Name files clearly: "2026 1099-DIV Brokerage A.pdf."
4. Drop the filed return PDF into "Filed" with the e-file acceptance email.
5. Keep the folder at least three years after filing, longer for property basis records and Form 8606, which you need until the asset is sold or the IRA is empty.

Illustration

Jamie's 2026 checklist: two W-2s (job change in June), a 1099-INT from a high-yield savings account ($310), a consolidated 1099 from a brokerage with $1,200 of dividends and a fund sale, a 1098-E for $1,100 of student loan interest, an HSA 5498-SA, and a $600 receipt from a food bank. Last year's return shows a $2,000 capital loss carryover. Jamie's software asks for every one of these. Because they're in one folder, the return takes 50 minutes. The carryover alone saves $440 at 22% (offsetting $2,000 of ordinary income), and it would have been missed without last year's return.
