What Documents Do I Need for Tax Season?

The number one thing that slows down tax preparation is missing documents. You sit down with your accountant, start going through everything, and realize you are missing a 1099, forgot about a stock sale, or never tracked your mileage.

This checklist covers what you need, whether you are filing as an individual, a freelancer, or a business owner. Print it out, check things off as you gather them, and you will have a much smoother tax preparation experience when it is time to file.

For Everyone: Personal Information

Before anything else, make sure you have the basics ready:

• Social Security numbers for yourself, your spouse, and all dependents
• Date of birth for all dependents
• Bank account and routing number for direct deposit of your refund
• Last year's tax return (your accountant can pull forward key information)
• Identity Protection PIN (IP PIN) if the IRS issued one to you
• Copy of your driver's license or state ID (some states require this for e-filing)

Individual Income Documents

Gather every document that reports income you received during the year:

Employment Income

• W-2 from each employer you worked for during the year
• W-2G for gambling or lottery winnings

Investment and Retirement Income

• 1099-INT for bank interest earned
• 1099-DIV for dividends from stocks, mutual funds, or ETFs
• 1099-B for stock, bond, or crypto sales (your brokerage provides this)
• 1099-R for retirement account distributions (401(k), IRA, pension)
• 1099-SA for HSA distributions
• SSA-1099 for Social Security benefits received
• K-1 (Schedule K-1) if you are a partner in a partnership or shareholder in an S-Corp

Other Income

• 1099-NEC for freelance or contract work ($600+ from any single client)
• 1099-MISC for rents, royalties, prizes, or other miscellaneous income
• 1099-G for state tax refunds or unemployment compensation
• 1099-S for real estate sale proceeds
• 1099-C for cancelled or forgiven debt
• 1099-K for payment processor income (PayPal, Venmo, Stripe, Square) if over $600

Tip: Most 1099 forms are due to you by January 31. If you are missing one, contact the payer directly. You are still required to report the income even if you never receive the form.

Individual Deductions

These documents help your tax professional find every deduction you are entitled to:

Housing

Organizing Tips That Actually Help

After working with thousands of clients, here are the things that make the biggest difference:

1. Use a Dedicated Folder

Physical or digital, have one place where tax documents go as they arrive. January through March is when most forms come in. Drop them in the folder the day you receive them.

2. Separate Business and Personal

If you are self-employed, keep business and personal expenses in separate bank accounts and credit cards. This alone saves hours of sorting at tax time.

3. Track Mileage Throughout the Year

Reconstructing a year of driving from memory does not work. Use a mileage tracking app (MileIQ, Everlance, or even a simple spreadsheet) starting January 1.

4. Keep Receipts for Anything Over $75

The IRS does not require receipts for expenses under $75 (except lodging), but keeping them for larger purchases protects you in an audit. A photo on your phone counts.

5. Do Not Wait for Every Document

If you are still waiting on one or two forms in late March, let your tax professional know. They can often prepare your return with estimates and amend later if needed. This is better than filing an extension and forgetting about it until October.

6. Review Last Year's Return

Your prior year return is a roadmap. Look at every line item and ask: "Do I have the document for this?" It catches things you might otherwise forget, like that small brokerage account or the rental income from a side property.

What If You Are Missing Something?

Do not panic. Here is what to do:

• Missing W-2: Contact your employer's HR or payroll department. They are required to provide it by January 31.
• Missing 1099: Contact the payer. You can also check the IRS Wage and Income Transcript (available mid-February) to see what has been reported under your SSN.
• Lost receipts: Check your bank and credit card statements for the transactions. For most audit purposes, bank records are acceptable backup documentation.
• No mileage log: You can reconstruct a reasonable estimate using your calendar (appointments, client meetings) and Google Maps for distances. It is not ideal, but it is better than claiming nothing.

The Payoff of Being Prepared

Walking into your tax appointment with everything organized does two things. First, it reduces the time (and cost) of preparation because your accountant is not chasing documents for weeks. Second, it ensures nothing gets missed. Forgotten deductions are money left on the table, and for business owners, the amounts add up fast.
