The phrase “tax season” often brings a rush of anxiety, but it doesn’t have to. For Houston residents, professionals, and small business owners, starting your 2026 tax preparation early is the single best way to ensure compliance and maximize your tax deductions. Waiting until the last minute guarantees missed opportunities and added stress.
This Tax Preparation Checklist is designed by our experienced Houston CPA firm to simplify the process, helping you organize your records and gather the necessary documents to claim every credit and deduction you are due. Don’t just file your taxes—strategize them.
2026 Tax Preparation Checklist
Phase 1: The Essential Documents Checklist (Personal & ID)
Before you dive into complex deductions, you must secure the foundational documents. This section is non-negotiable for an accurate and timely tax filing in Houston.
1. Personal Information
- Prior-Year Tax Return: This is your map! It provides carry-forward details (like depreciation or capital losses) and simplifies referencing your Adjusted Gross Income (AGI).
- Identification: Social Security Numbers (SSN) or Individual Taxpayer Identification Numbers (ITIN) for yourself, your spouse, and all dependents.
- Bank Information: Routing and account numbers for direct deposit of your refund.
- IRS Notices: Any correspondence received from the IRS or state tax agencies during the year (e.g., CP01A Notice for IP PIN).
2. Income Documentation
The forms you receive from your employer, banks, and investment firms are the backbone of your income reporting.
- W-2s: Wages, salaries, and tips from all employers.
- 1099 Forms:
- 1099-INT: Interest income from banks.
- 1099-DIV: Dividends and distributions from investments.
- 1099-B: Proceeds from stock/security sales (required for capital gains/losses).
- 1099-NEC/MISC: Payments for freelance or gig economy income.
- K-1s: Income from partnerships, S-Corporations, trusts, or estates.
- Retirement Income: Forms 1099-R for pension or annuity distributions.
Phase 2: Maximizing Your Tax Deductions and Credits
This is where proactive tax planning pays off. Ensure you have the documentation for all potential above-the-line and itemized deductions.
A. Home and Property Deductions (Crucial for Houston Homeowners)
- Form 1098: Mortgage interest statement from your lender.
- Property Taxes: Records of payments for Houston property taxes (a major component of the SALT deduction).
- Refinancing/Purchase: Closing statements (HUD-1 or Closing Disclosure) if you bought, sold, or refinanced a property.
B. Health, Education, and Dependent Costs
- Medical Expenses: Receipts for unreimbursed payments (doctors, dentists, tests, insurance premiums) that exceed the AGI threshold.
- Education Expenses:
- Form 1098-T: Tuition payments (required for the American Opportunity and Lifetime Learning Credits).
- Records of student loan interest paid (Form 1098-E).
- Childcare Costs: Statements from your daycare or provider (including their name, address, and Tax ID) for the Child and Dependent Care Credit.
C. Retirement and Charitable Giving
- Retirement Contributions: Records of contributions to Traditional or Roth IRAs, SEP-IRAs, or 401(k) plans (especially crucial for self-employed individuals).
- Charitable Donations: Bank records or receipts for cash donations and written acknowledgments from organizations for non-cash donations over $250.
Phase 3: The Small Business & Self-Employed Checklist
For Houston entrepreneurs and freelancers, your preparation is more complex. Integrating your accounting records makes all the difference.
| Category | Required Documentation | Key Deduction |
|---|---|---|
| Business Income | Final Profit and Loss (P&L) statement; all 1099-NEC/MISC received; sales revenue summary. | Qualified Business Income (QBI) Deduction (Section 199A) |
| Business Expenses | Organized receipts/invoices for all operating costs (advertising, utilities, rent). | General business expenses |
| Fixed Assets | Purchase date and cost of any equipment or large asset purchases made during the year. | Section 179 and Bonus Depreciation |
| Home Office | Records of the square footage of your dedicated office space and the total square footage of your home. | Home Office Deduction |
| Vehicle Use | Detailed mileage log showing business vs. personal miles (or records of actual expenses like gas and repairs). | Business use of vehicle deduction |
Pro-Tip: If you utilize our bookkeeping or payroll services, much of this data is already organized and ready for the final transfer to your tax forms, streamlining your entire filing process.
Final Review: 2026 Tax Preparation
Before signing your tax returns, a final review ensures you haven’t missed a simple, yet high-impact, opportunity.
- Check Your Credits: Did you claim the Earned Income Tax Credit (EITC), Child Tax Credit (CTC), or Premium Tax Credit if applicable?
- Verify Estimated Payments: Did you accurately record all federal and state estimated tax payments made throughout the year?
- Review Carry-Forwards: Consult your prior-year return to ensure you haven’t forgotten to carry forward any losses or credits.
- Confirm Personal Data: Double-check all names, SSNs, and birth dates—errors here lead to lengthy IRS delays.
