Gather Your Personal Details and Past Records
Getting your tax documents in order is the first and most important step to a smooth tax season. Being organized can save you time, reduce errors, and help you claim all the deductions and credits you deserve.
To start, you need your basic identifying information and a look back at your previous tax filings. This information forms the foundation of your current year’s return.
- Social Security numbers (SSN) or Tax IDs (ITIN): You’ll need these for yourself, your spouse, and any dependents.
- Dates of birth: For everyone listed on your return.
- Prior year’s federal and state tax returns: These are super helpful for reference, seeing carryovers (like losses), and ensuring consistency.
- Photo ID: A driver’s license often helps with e-filing security.
2. Collect All Your Income Documents
This section is all about proving where your money came from. Make sure you have every piece of income documentation, whether it’s from an employer or your own business.
- W-2 forms: If you worked for an employer, you’ll get one of these.
- 1099 forms: These come in many types, detailing various income sources:
- 1099-NEC: For nonemployee compensation (freelancers, contractors).
- 1099-K: For payment card and third-party network transactions (gig workers).
- 1099-DIV: For dividends from investments.
- 1099-INT: For interest income from banks.
- 1099-B: For capital gains from selling stocks or other investments.
- 1099-G: For unemployment benefits or state/local tax refunds.
- 1099-S: For proceeds from real estate sales.
- Other income statements: This includes things like alimony received or gambling winnings (Form W2-G).
3 . Documentation for Deductions and Credits
This is where you can often save a lot of money! Deductions lower your taxable income, and credits directly reduce your tax bill. Keep meticulous records for everything here.
- Charitable donations: Receipts or acknowledgment letters for cash and non-cash gifts.
- Medical expenses: If you itemize, gather bills, receipts, and insurance premium statements.
- Childcare costs: Provider’s name, address, and tax ID or SSN, plus payment records.
- Education expenses: Form 1098-T for tuition, plus receipts for books and supplies.
- Home mortgage interest: Form 1098 from your lender.
- Real estate and property taxes: Records of payments to your local government.
- Business expenses (for self-employed/freelancers): This is crucial!
- Mileage logs: Detailed records of business travel. (More on this later!)
- Receipts: For supplies, equipment, software, and services.
- Home office expenses: Utility bills, rent/mortgage, insurance, and repairs.
- Health savings account (HSA) contributions and distributions: Form 1099-SA and 5498-SA.
- Student loan interest: Form 1098-E.
4 . Payments and Estimated Taxes
Make sure you account for any money you’ve already paid towards your self-employed taxes throughout the year.
- Records of estimated tax payments: If you’re self-employed, these are typically made quarterly using Form 1040-ES.
- Taxes withheld: This amount is shown on your W-2 or 1099 forms.
- Bank information: For direct depositing your refund or directly paying any taxes owed.
5 . Specialized Documentation for Unique Tax Situations
Today’s tax landscape is always changing. Some situations require specific paperwork to claim credits or report income accurately.
- Cryptocurrency transactions: Records of all buys, sells, and exchanges.
- Electric Vehicle Clean Vehicle Credit: Dealer reports and MSRP (Manufacturer’s Suggested Retail Price) for eligible vehicles.
- Stock options: Details like grant dates, exercise dates, and fair market values.

Missing or Incorrect Forms? Don’t Panic!
It happens. Sometimes forms arrive late, or you spot an error. Here’s what to do:
- Contact the issuer: Reach out to your employer, bank, or broker if a form is missing or incorrect.
- Check online accounts: Many institutions provide digital copies of your tax forms.
- File an extension: If you’re waiting on a form, it’s better to file an extension (Form 4868) than to file late or with incomplete information. This gives you more time to get your documents in order without penalty for late filing.
Overview of Key Deadlines
Understanding tax deadlines is crucial to avoid penalties. The general filing deadline for most individuals is typically April 15th.
| Action | Typical Deadline | Notes |
|---|---|---|
| Tax Day (Filing & Payment) | April 15th | Unless a weekend or holiday, then the next business day. |
| Estimated Tax Payments (Quarterly) |
April 15th (Q1) June 15th (Q2) September 15th (Q3) January 15th (next year, Q4) |
Quarterly estimated payments for self-employment income. |
| Request for Extension | April 15th | Provides a 6-month extension to file, not to pay. |
Remember, an extension to file is not an extension to pay. If you think you’ll owe taxes, pay an estimate by the April deadline to avoid penalties.

Customer Story: Rebuilding a Mileage Log for Tax Season
I work as a physical therapist, so I’m on the road every day driving between patients. When tax season started creeping up, I realized I hadn’t kept a proper mileage log all year. I panicked when my accountant sent over a tax preparation checklist, and mileage was right at the top of my priorities.
Then I found an app that turns Google Maps Timeline data into a complete mileage log. I downloaded it, imported my Timeline from my phone, and watched months of drives appear in minutes. No guessing routes, no digging through old notes. Sorting personal and business trips was simple, and generating a final log took just one tap.
For the first time, I feel prepared. Having my mileage organized and compliant is a huge relief, especially with tax season right around the corner.
Your Tax Preparation Summary
Getting ready for tax season doesn’t have to be a headache. By following a clear tax preparation checklist, you can save time, avoid mistakes, and maximize your returns.
Here’s a quick recap of your actionable steps:
- Start Early: Begin gathering documents well before the deadlines.
- Organize by Category: Use folders (physical or digital) for personal, income, deduction, and payment records.
- Track Everything: Especially business mileage and expenses.
- Confirm All Forms: Make sure you receive all necessary W-2s and 1099s.
- Review Last Year’s Return: Use it as a guide for what you’ll need this year.
- Seek Help If Needed: Don’t hesitate to consult a tax professional for complex situations.
FAQ
When do W-2s and 1099s arrive, and what if they’re late?
W-2s are due to you by January 31; many 1099s are due then too, while investment 1099s can arrive in February or March. If a form hasn’t arrived by mid-February, contact the issuer. You can also request an IRS wage and income transcript or file an extension.
What records help me get deductions and credits?
Receipts for charitable gifts, medical bills, childcare, educator expenses, and state/local taxes you paid. Mortgage interest (Form 1098), property taxes, and student loan interest (Form 1098-E). Education costs (Form 1098-T and statements), adoption expenses, and retirement contributions.
Should I itemize or take the standard deduction?
Most people take the standard deduction because it’s larger than their itemized expenses. Itemize if your deductible costs like mortgage interest, SALT taxes (subject to the cap), charitable gifts, and big medical bills exceed the standard deduction. Check the current standard deduction on IRS.gov before you decide.
I’m a freelancer/contractor. What’s on my checklist?
All income records (invoices, 1099-NEC/1099-K, and deposits) and business expense receipts. Mileage logs, home-office details, phone/internet split, equipment, and supplies. Include quarterly estimated tax payments and any sales tax you collected.
