Tax Season Simplified: The Ultimate Document Checklist for 2026
Let’s be real: tax season isn't exactly the highlight of the year. But if you are the type of person who values efficiency and hates digging through stacks of mail at the last minute, we’ve got you covered. Whether you are a freelancer, a 9-to-5er, or a crypto enthusiast, staying organized is the best way to avoid a headache in April.
March is the "golden window" to gather your paperwork. Getting ahead now means getting your refund faster. Here is everything you need to have ready before you hit "file."
Personal Info & Identification
The IRS needs to know exactly who is filing. Don't rely on memory; have these digital or physical copies ready:
- Social Security Number (SSN) or ITIN: This applies to you, your spouse, and any dependents.
- Bank Account Details: You will need your Routing Number and Account Number from your Inter US account to receive your direct deposit refund.
- Photo ID: A valid Driver’s License or Passport.

Income Proof (The "Paper Trail")
This is where most people get stuck. Depending on how you made your money last year, look out for these specific forms:
- Form W-2: If you worked as a traditional employee.
- Form 1099-NEC: Essential for freelancers, side-hustlers, and Gig Workers.
- Form 1099-INT: For any interest you earned on your savings or investment accounts.
- Investment Reports: Statements from your trading apps showing your capital gains or losses in stocks and crypto.
Deductions: Don’t Leave Money on the Table
Deductions lower your taxable income, which usually means a bigger refund for you. Keep track of:
- Student Expenses: Look for Form 1098-T for tuition payments.
- Health Costs: Records of significant medical or dental expenses.
- The Home Office: If you are self-employed, track your internet bill and a portion of your utilities.
The "Save & Print" Checklist

How to Organize Like a Pro
Ditch the physical folder. If you are the type of person who prefers a digital-first lifestyle, use a mobile scanning app or a dedicated cloud folder named "Tax Season 2026." Every time an email arrives with a form, move it there immediately.
Filing early does more than just reduce stress; it is one of the best ways to protect yourself against identity theft and ensure your money reaches you sooner.
Common Last-Minute Questions
People often ask if they need to keep every single coffee receipt. The rule is simple: only keep what is strictly business-related or a qualified deduction. If a receipt seems blurry or unimportant, scan it anyway just in case. When in doubt, a quick chat with a tax professional can save you from unnecessary stress later.
Let the Inter App do the heavy lifting
Think of your app as a digital command center for tax season. Instead of digging through old mail or scrolling through endless emails, you can find your key financial data exactly where you expect it to be.
- Your Tax Documents Hub: No more guessing games. The app centralizes your consolidated earnings and interest forms. To grab them, just head to the Invest section, tap the Settings icon (the gear), and select Documents.
- Seamless Reporting: If you’ve been active in the market, the app provides the clear reports you need for your stock and crypto gains or losses. It makes handing over accurate data to a tax preparer—or a software—totally painless.
- Speed Up Your Refund: Why wait for a paper check? When filing, use your Inter US Routing and Account Number for Direct Deposit. This is the fastest way to get your money exactly where it belongs: in your balance.
Direct Deposit: The finish line
When the IRS determines you are owed a refund, you have a choice: wait weeks for a physical check or get it instantly via Direct Deposit.
For anyone who prefers immediate access to their funds, simply enter your Inter US banking details into your tax software. Once the IRS processes your return, the money lands in your account automatically. From there, you can move it into your High-Yield Savings or use it for your next big goal.
Pro-Tip: The Digital Paper Trail
The smartest way to stay organized is to avoid paper altogether. Use your app to monitor monthly statements and cross-reference them with your 1099 forms. By keeping everything digital, you eliminate the risk of losing important info and make future filings even faster.
