Tax Preparation Checklist: What to Bring to Your Tax Preparer (2025 Edition)

Education only, not tax advice. Requirements can vary by filing status, income sources, and life changes. Use this as a preparation roadmap.

Why showing up prepared changes everything

A tax return is not just a form — it’s a story backed by documentation. When you bring complete records:

• Your return is faster to prepare.
• You reduce back-and-forth emails and delays.
• You lower the risk of missing income or deductions.
• You strengthen your support file if questions ever arise.

Small business add-on checklist

If you have a side hustle, Schedule C business, or growing company, the quality of your bookkeeping becomes the difference between: a clean return and a painful reconstruction.

Core business records

• Profit & Loss statement (year-to-date).
• Balance Sheet (if you track assets/loans).
• Business bank and credit card statements.
• Sales reports (Shopify, Square, Stripe, Amazon, etc.).
• 1099s you received.

Expense proof & special areas

• Vehicle mileage logs or business-use summaries.
• Home office details (square footage, utility totals if used).
• Equipment purchases and receipts.
• Contractor payments and W-9s.
• Payroll reports if you have employees.

Capital gains & investing documents

If you sold stocks, crypto, or other assets, bring:

• 1099-B statements.
• Brokerage year-end summaries.
• Crypto exchange reports (if available).
• Cost basis notes for anything not clearly tracked.

These guides can help you understand the story behind those forms:

Life changes that need a quick note

Even when you have perfect documents, your preparer still needs your “real-life updates.” Make sure you mention:

• Marriage or divorce.
• New child or change in custody.
• Move to a new state.
• Starting or closing a business.
• Major asset sales or big life events.

What to expect from a good tax preparer

You should feel comfortable asking:

• What documents are still missing?
• Where is income being reported and why?
• Which deductions are being claimed and what supports them?
• What are the biggest risk areas on this return?

The best relationship is collaborative: you bring full facts, your preparer brings structure and law.

FAQs

Do I need my prior-year return?

If you’re working with a new preparer, yes — it helps confirm carryovers, basis items, and the pattern of your filing history.

What if I’m missing a form?

Don’t guess. Let your preparer know what income stream you expect. There may be ways to retrieve documents or confirm totals with account statements.

Is a 1099-K automatically taxable income?

Not always. It’s a reporting form that may include business income, personal reimbursements, or even personal-item sales. The key is matching it to your records.

What’s the biggest mistake small businesses make before tax time?

Waiting until year-end to “fix the books.” Monthly reconciled bookkeeping reduces errors and missed deductions.
