Tax season might not officially kick off until next year, but smart business owners know that getting ready early is the key to a smooth and stress-free experience. The more you prepare now, the fewer surprises you’ll face later, and the easier it will be to file confidently and on time.

Whether you’re DIY-ing or working with a tax pro, this checklist will help you get your finances in order before the year wraps up.

✅ 1. Reconcile All Accounts

Make sure your bank accounts, credit cards, and payment platforms (like PayPal or Stripe) are fully reconciled through the end of October. Keep up with November and December as you go.

Why it matters: Reconciliation ensures every transaction is accounted for and eliminates surprises during tax prep.

✅ 2. Review and Categorize Expenses

Go through your books and make sure all expenses are correctly categorized. If you’re not sure whether something counts as a deductible expense, make a note to ask your tax pro.

Common categories to review:

• Software and subscriptions
• Office supplies
• Marketing and advertising
• Contractor payments
• Travel and meals
• Professional development

✅ 3. Clean Up Your Books

If your books are messy, now is the time to clean them up before tax season hits.

Check for:

• Duplicate or missing transactions
• Unmatched deposits or transfers
• Misclassified expenses
• Negative or incorrect balances

If you’re behind on your bookkeeping, this is a great time to hire help so you can catch up before the deadline rush.

✅ 4. Gather Key Tax Documents

Start compiling the documents you’ll need for tax filing. This includes:

• 1099s from contractors (and making sure you’ve sent any that you owe)
• Income reports from all payment platforms
• Mileage logs if you use a vehicle for business
• Home office or business use-of-home details (square footage, utility bills, etc.)
• Business loan or grant documentation

✅ 5. Check for Estimated Tax Payments

If you’re making quarterly payments, make sure you’ve paid the first three and schedule the final one for January. Keep a record of each payment so it’s easy to reference when you file.

✅ 6. Review Owner’s Pay and Distributions

If you’re an LLC, S Corp, or partnership, now is the time to make sure you’ve paid yourself appropriately and documented any distributions. This can impact how your income is reported and taxed.

✅ 7. Meet with Your Tax Pro Early

Book your appointment now before their calendar fills up. An early meeting gives you time to make final adjustments, plan for your tax liability, and avoid the last-minute scramble.

✅ 8. Plan for What’s Next

While you’re reviewing your numbers, start thinking ahead. What worked financially this year? What didn’t? Use this insight to set financial goals and systems for the new year.

Start Early, Stress Less

Tax prep doesn’t have to be overwhelming, especially if you start now. A few hours of prep in November and December can save you time, money, and serious stress in the new year.

✔ Review your books
✔ Organize your documents
✔ Connect with your tax pro

You’ve got this. Future you will be so glad you started early.
