Catch-Up Bookkeeping Before Tax Season: A Complete Checklist
By Accounting Ketchup Team · Last updated April 13, 2026
Getting your books caught up before tax season doesn't have to be overwhelming. Follow this 8-step checklist in order, and you'll go from "behind" to "CPA-ready" as efficiently as possible.
Before You Start: Assess the Situation
Answer these questions to scope the project:
- How many months behind are you? (This determines cost and timeline)
- How many bank/credit card accounts are involved?
- Do you have a QuickBooks Online account set up?
- What's your tax filing deadline?
Timeline estimate: DIY takes 15-40+ hours for a full year. A professional AI-powered service takes 3-7 days.
The 8-Step Catch-Up Checklist
Step 1: Gather All Bank and Credit Card Statements
Download statements from every account used for business for the entire catch-up period. Include:
- ☐ Business checking account(s)
- ☐ Business savings account(s)
- ☐ Business credit card(s)
- ☐ PayPal, Stripe, Square, or other payment processor accounts
- ☐ Any personal accounts used for business expenses
DIY time: 1-2 hours. Service time: 0 (they pull from QBO bank feeds).
Step 2: List All Accounts and Financial Institutions
Make a complete list of every financial account your business touches. Missing an account means missing transactions — and your books won't balance.
- ☐ Bank accounts (checking, savings)
- ☐ Credit cards
- ☐ Payment processors (Stripe, PayPal, Square)
- ☐ Platform accounts (Shopify, Amazon, Etsy)
- ☐ Loan or line of credit accounts
Step 3: Check Your Last Reconciled Date
In QuickBooks Online, check when each account was last reconciled. This tells you exactly where the "caught up" period ends and the "behind" period begins.
How to check: In QBO, go to Settings → Reconcile → select an account. It shows the last reconciled date and closing balance.
Step 4: Identify Gaps and Problem Areas
Look for:
- ☐ Months with no categorized transactions
- ☐ Large "uncategorized" or "Ask My Accountant" balances
- ☐ Bank balance mismatches (QBO balance vs. actual bank balance)
- ☐ Duplicate transactions
- ☐ Personal expenses mixed with business
Step 5: Categorize Transactions (or Hire a Service)
This is the big one. Every transaction needs a category.
DIY approach: Open each month's bank feed in QBO. Review each transaction. Assign a category. Repeat for every month, every account. Plan for 1-3 hours per month of catch-up.
Professional approach: Connect your QBO to an AI-powered service. AI categorizes 80-90% automatically; humans review the rest. Done in days, not weeks.
Step 6: Reconcile Every Account, Every Month
After categorizing, reconcile each bank and credit card account for each month. The reconciled balance in QBO should match your bank statement balance exactly. If it doesn't, find and fix the discrepancy before moving on.
DIY time: 15-30 minutes per account per month. Service: Included in the catch-up process.
Step 7: Run P&L and Balance Sheet Reports
Once everything is categorized and reconciled, run these reports:
- ☐ Profit & Loss (full year or catch-up period)
- ☐ Balance Sheet (as of period end)
- ☐ Bank reconciliation summary for each account
Review for obvious errors: negative expenses, revenue in wrong categories, missing months. Fix any issues before sending to your CPA.
Step 8: Send Clean Books to Your CPA
Give your CPA access to your QuickBooks Online file (Accountant access). Also provide:
- ☐ P&L statement for the full tax year
- ☐ Balance Sheet as of year-end
- ☐ 1099s received
- ☐ Any 1099s you need to issue
- ☐ Mileage/vehicle log (if applicable)
- ☐ Home office details (if applicable)
