2. Organize Financial Records

Good bookkeeping is the foundation of accurate tax filing.

Prepare:

• Profit and Loss Statement
• Balance Sheet
• General Ledger
• Cash Flow Statement
• Trial Balance
• Bank Statements
• Credit Card Statements

Accurate financial statements help ensure your reported income matches your accounting records.

3. Reconcile Bank and Credit Card Accounts

Before filing taxes, verify that:

• Every transaction is recorded
• Deposits match bank statements
• Expenses are categorized correctly
• Outstanding transactions are reviewed

Reconciliation helps eliminate errors before they become tax issues.

4. Review Business Income

Your reported income should include every revenue source.

Examples include:

• Sales revenue
• Service income
• Consulting fees
• Online sales
• Interest income
• Rental income (if applicable)
• Investment income related to the business

Missing income can trigger IRS notices or audits.

5. Collect Expense Documentation

Proper documentation is critical during business tax preparation.

Gather receipts for:

• Office supplies
• Marketing expenses
• Advertising
• Software subscriptions
• Internet and phone bills
• Utilities
• Insurance premiums
• Professional services
• Accounting fees
• Legal expenses
• Business travel
• Meals
• Vehicle expenses

Digital copies are perfectly acceptable if they’re organized and accessible.

6. Review Payroll Records

If you have employees, verify:

• Payroll reports
• Employee wages
• Payroll tax deposits
• Federal withholding
• State withholding
• Social Security taxes
• Medicare taxes
• Unemployment taxes

Ensure W-2s have been issued accurately and payroll tax filings are complete.

7. Prepare Contractor Information

If you paid independent contractors during the year:

Review:

• Form W-9
• Contractor invoices
• Payment records
• Form 1099-NEC (where applicable)

Proper contractor reporting helps avoid IRS penalties.

8. Verify Business Deductions

Many small businesses miss valuable deductions every year.

Common deductions include:

Home Office

If you qualify, you may deduct eligible home office expenses.

Business Vehicle

Mileage or actual vehicle expenses may be deductible.

Office Equipment

Computers, printers, furniture, and office equipment.

Software

Accounting software, CRM tools, project management software, cloud storage, and subscriptions.

Professional Services

Expenses paid to:

• Accountants
• Attorneys
• Consultants
• Marketing agencies

Employee Benefits

Including:

• Health insurance
• Retirement contributions
• Training programs

9. Review Fixed Assets

Did you purchase equipment during 2026?

Review:

• Computers
• Machinery
• Office furniture
• Vehicles
• Technology upgrades

These purchases may qualify for depreciation or Section 179 deductions.

10. Calculate Estimated Tax Payments

Compare:

• Estimated taxes paid
• Actual tax liability

This helps determine whether you’ll owe additional taxes or receive a refund.

11. Check State and Local Tax Requirements

Federal taxes aren’t your only responsibility.

Depending on your state, you may need to file:

• State income tax
• Franchise tax
• Sales tax
• Business license renewals
• Local business taxes

Every state has different filing rules and deadlines.

12. Review Tax Credits

Many businesses overlook valuable tax credits.

Potential opportunities include:

• Research and Development (R&D) Credit
• Work Opportunity Tax Credit
• Energy Efficiency Credits
• Employer Retirement Plan Credits
• Disabled Access Credit

A qualified tax accountant can identify credits you may not know about.

13. Review Inventory

If your business carries inventory:

Verify:

• Beginning inventory
• Purchases
• Ending inventory
• Inventory adjustments

Accurate inventory valuation directly impacts taxable income.

14. Separate Business and Personal Expenses

One of the biggest tax mistakes is mixing personal and business expenses.

Before filing:

• Review owner withdrawals
• Separate reimbursements
• Correct personal charges

Clean records make tax preparation significantly easier.

15. Verify Tax Forms

Depending on your business structure, you may need:

• Schedule C
• Form 1065
• Form 1120
• Form 1120-S
• Form 941
• Form 940
• Form W-2
• Form 1099

Submitting the correct forms prevents unnecessary delays.

Common Small Business Tax Mistakes to Avoid

Many businesses pay more taxes than necessary simply because of avoidable mistakes.

Watch out for:

• Missing receipts
• Incorrect expense categorization
• Forgetting deductible expenses
• Missing filing deadlines
• Payroll tax errors
• Incomplete contractor information
• Not reconciling accounts
• Ignoring estimated tax payments
• Mixing business and personal finances
