If you’ve ever hit January and thought, “I’ll deal with it at tax time,” you’re not alone.
But here’s the truth: tax time is always easier when your books are “tax-ready” before your CPA touches them.
It saves you time, saves you money (fewer back-and-forth questions), and reduces the chance of missed deductions or incorrect numbers.
This quick checklist is built for small business owners who want a simple plan, without turning bookkeeping into a second job.
What “tax-ready” actually means (in plain English)
Tax-ready doesn’t mean you’re a CPA. It means:
Your accounts are reconciled (your books match the bank)
Transactions are categorized (no “uncategorized pile”)
Income and expense totals make sense
Your key reports are clean: Profit & Loss + Balance Sheet
You can answer basic questions quickly if your tax pro asks
When these are done, your CPA can do their job faster—with fewer questions—and you avoid last-minute scrambling.
Year-end checklist (do these in order)
1) Reconcile every bank and credit card account (through December)
This is step one for a reason. If your “cash in bank” doesn’t match reality, your reports can be wrong even if everything looks organized.
Quick check: If your Balance Sheet cash balance ≠ your actual bank balance, reconciliation is not done yet.
2) Clear the uncategorized pile (no “Ask my accountant” mountain)
Uncategorized transactions create vague reports and delays.
categorize consistently (same vendor = same category)
split transactions when needed (example: Costco = supplies + snacks)
add short memos on weird one-offs (“client refund,” “reimbursed,” etc.)
3) Confirm income totals make sense
Do a reality check:
compare this year vs last year
compare average month vs your busiest month
check for missing deposits (especially if you invoice)
If you use Stripe/PayPal/Square, remember:
deposits may be net of fees
fees should be tracked separately (so income isn’t understated)
4) Review big purchases (equipment, software, marketing)
This is where deductions can get missed. Look for:
laptops, phones, equipment
annual software subscriptions
major marketing spends (ads, websites, branding)
Tip: If something is a bigger purchase, add a memo like “new laptop for business” so it’s easy to spot later.
5) Confirm mileage logs (if you track mileage)
If you’re deducting mileage, your tax pro may ask for support. Make sure you have:
total business miles
date range covered
a system (app log, spreadsheet, calendar notes)
6) Confirm contractor totals + documentation (1099s)
If you pay contractors, you’ll want to know now—not on January 31.
Do a quick contractor review:
list who you paid
total paid to each person/business
confirm W-9s are collected (recommended)
note if payments were by credit card/PayPal (your tax pro will advise how that’s handled)
7) Export (or save) your year-end reports
These are the usual basics your CPA needs:
Profit & Loss (P&L) for the year
Balance Sheet as of December 31
Optional but helpful:
General Ledger
Expense detail report
A/R and A/P summaries (if you invoice or have bills)
A simple “one-hour” version if you’re busy
If you only have one hour this week:
Reconcile your main checking account
Categorize the uncategorized transactions
Export the P&L + Balance Sheet
That alone puts you ahead of most business owners.
When you should get help (instead of forcing it)
You’ll usually save time and money by getting help if:
you haven’t reconciled in months
the books don’t match the bank
“uncategorized” is out of control
you’re mixing personal + business spending
you’re unsure how to handle transfers, refunds, or merchant fees
