Tax Documents Checklist: Get Ready for Tax Time

Tax Documents Checklist: What to Bring (Oklahoma)

If you live in Oklahoma and you’re wondering what to gather before tax season, this tax documents checklist will make it simple. Most delays happen for one reason: forms arrive in different weeks, and people send items in pieces. This guide helps you collect everything first, then submit it one time—so your return can be prepared efficiently and with fewer follow-up questions.

A common question we hear every year is: what documents do I need to file taxes if my income comes from more than one place (W-2, retirement, investments, side gigs, or a small business)? The answer depends on your situation, but the checklist below covers the most common items for individuals and for many businesses.

Pro tip: Use this as a tax documents checklist. Gather your documents, sort them into the categories below, and then send everything all at once.

How to Get Your Documents to Roger Ely CPA

To protect your privacy and keep your file organized, we recommend sending documents through our secure portal whenever possible.

  • Upload via Verifyle (preferred)
    • Existing clients: Click Client Portal on our website (upper right-hand side).
    • New clients: Please call our office so we can email you a Verifyle link.
  • Or bring documents by our Seminole office (if you prefer in-person delivery).

If you’d rather not drive, secure upload is usually the fastest and easiest option.

Before You Start: The 60-Second Checklist

This makes everything easier before you upload or drop off:

  • Make two piles (or folders): Individual and Business
  • Put all “still waiting on it” items in one place (brokerage statements, K-1s, 1095-A, etc.)
  • Then send everything all at once

This is the simplest way to use a tax documents checklist for a CPA appointment without feeling overwhelmed.

Why This Checklist Matters for Oklahoma Taxpayers

Many Oklahoma households have a mix of income sources—W-2 wages, retirement distributions, investment accounts, a side gig, or a rental property. Even one missing form can slow down your return, trigger a notice later, or cause you to miss a deduction or credit you qualify for.

This checklist also helps you avoid the most common “surprise” issue: forms like brokerage statements, K-1s, or Marketplace health insurance documents arriving later than expected. When you know what to watch for, you can plan ahead.

And yes—people still ask it every year: what documents do I need to file taxes if I have multiple accounts, sold something online, or started a small business? The categories below will keep you on track.

Tax Documents Checklist for Individual Returns

 

If you’re filing only an individual return, you can use the checklist below and stop there.

1) Personal and Household Information

These items help ensure your identity, filing status, dependents, and banking details are correct:

  • Photo ID for taxpayers
  • Social Security numbers (or ITINs) and dates of birth for everyone on the return
  • Current address and best phone/email
  • Bank routing and account number (for direct deposit or payment draft)
  • Last year’s tax return (especially if you’re a new client)

If anything changed in your household (marriage, divorce, new child, move, name change), include a quick note.

2) Income Documents

If you’re asking what documents do I need to file taxes for income, think of it this way: any form that reports money you earned, received, or withdrew should be included.

Common examples include:

  • W-2s
  • 1099s such as 1099-NEC, 1099-MISC, 1099-INT, 1099-DIV, 1099-R, 1099-G, SSA-1099
  • Unemployment documents (often a 1099-G)
  • Retirement and pension distributions (often 1099-R)
  • Brokerage statements for interest/dividends and sales (stocks, ETFs, mutual funds, bonds)
  • K-1s from partnerships, S-corps, trusts, or estates (if applicable)
  • Other income: side jobs, online sales, gig platforms, rental income, prizes/winnings

Tip: If you worked in more than one state during the year, mention that early.

3) Deductions and Credits (Send What Applies)

Provide the forms and details that apply to your situation:

  • Mortgage interest and property tax (commonly Form 1098 and property tax receipts)
  • Charitable giving documentation (cash and non-cash donations)
  • Childcare expenses: provider name, EIN/SSN, and total paid
  • Education: Form 1098-T and related documentation if needed
  • Health insurance: Form 1095-A if you had Marketplace coverage
  • Retirement contributions and HSA documentation
  • Energy credits (solar, heat pump, windows/doors) with receipts and product info

If you’re unsure whether something matters, include it anyway or add a note.

4) Payments, Notices, and Prior-Year Items

  • IRS or state letters/notices you received (if any)
  • Estimated tax payment records (federal and state)
  • Prior-year return (especially for new clients or complex changes)

Most Commonly Missed Items (Individuals)

This is where many returns get delayed. If any apply, add them before you upload or drop off:

  • Student loan interest (Form 1098-E)
  • HSA documents (Form 1099-SA and/or 5498-SA)
  • IRA contribution form (Form 5498 often arrives later than other tax forms)
  • 1099-K forms (Venmo/PayPal/credit card processors)
  • Crypto activity (exchange statements for sales/trades)
  • Rental income/expenses (rents received and expense totals)
  • Identity Protection PIN (IP PIN) letter, if you have one

 

Business Returns Checklist (S-Corps & Partnerships — Due March 16, 2026)

 

This section is for calendar-year S-corporations and partnerships. For the 2025 tax year, the deadline is Monday, March 16, 2026 (because March 15 falls on a Sunday).

  • Legal business name, address, and EIN
  • Entity type (S-corp, partnership, LLC, etc.)
  • Ownership changes (new owners, percentage changes)
  • New state registrations, new locations, or major operational changes

2) Bookkeeping and Financials (Most Important)

Your business return depends on clean, final numbers. Please provide final, reconciled year-end financials—meaning your bank and credit cards are reconciled through 12/31.

  • Balance Sheet as of 12/31
  • General ledger (or accounting system export)
  • Bank and credit card statements (if not already fully reconciled)

3) Payroll

  • Year-end payroll reports (W-2/W-3 and quarterly reports)
  • Owner payroll details (if applicable)
  • Employer retirement contributions (if any)

4) Contractors (1099s)

  • Contractor list and totals paid
  • Confirmation that 1099s were filed (or copies / e-file confirmations)

If you paid contractors, confirm your 1099s are handled.

5) Assets, Vehicles, and Large Purchases

  • Equipment/furniture/computer purchases (date, cost, description)
  • Business vehicle use (business-use percentage and mileage totals/log)
  • Sale, trade-in, or disposal of assets

6) Loans and Interest

  • New loans or refinances (closing documents)
  • Year-end loan balances
  • Interest paid (loans, credit lines, business credit cards)

7) Owner Items (Commonly Needed)

  • Owner distributions and contributions (amounts taken out/put in)
  • Owner health insurance (especially for S-corp shareholders)

8) Inventory (If You Sell Products)

  • Beginning and ending inventory totals
  • Major inventory purchases (if not already captured in the books)

9) Other Items (If Applicable)

  • Rent/lease agreements (if new/changed)
  • Insurance totals (business policies)
  • Sales tax filings (if relevant)
  • One-time events (lawsuit settlement, disaster loss, major inventory write-off)

10) Prior-Year and Extension Information

  • Prior-year business return (if you’re new to us)
  • Any extension already filed and payment amounts (if applicable)
