Year-End Tax Prep Checklist
Everything your CPA will ask you for, in one list. Work through it in December and tax season becomes a handoff instead of a scramble.
1. Books & financial statements
- Every bank and credit card account reconciled through December 31 — book balances match statements
- Final P&L and balance sheet for the year, with no uncategorized or "miscellaneous" balances
- Year-end statements for every loan and credit line, so book balances match lender balances
- AR review — write off invoices you'll never collect; your CPA needs to know about bad debt
- Physical inventory count as of December 31, if you carry inventory
2. Payroll & contractors
- W-2s issued to employees and filed by January 31
- W-9s collected from every contractor you paid $600 or more, and 1099-NEC forms issued and filed by January 31
- All four quarterly payroll filings (Form 941) and the annual unemployment filing (Form 940) accounted for
- Owner compensation documented — salary vs. draws vs. distributions, clearly separated
3. Assets & big purchases
- Invoices and financing docs for equipment, vehicles, or property bought this year — your CPA decides how to depreciate or expense them
- A note of anything sold, junked, or traded in, so it comes off the books
- Mileage log or vehicle-use summary for business vehicles
4. Deduction documentation
- Home office details (square footage) if you claim one
- Health insurance premiums paid by the business, especially for owners
- Retirement contributions made or planned before the filing deadline
- Any business expenses paid from personal accounts — documented and reimbursed (and next year, keep them separate)
5. State filings
- Arkansas: annual franchise tax report due to the Secretary of State by May 1
- Texas: franchise tax report and Public Information Report due to the Comptroller by May 15; business personal property rendition due to your county appraisal district by April 15
- Sales tax filings current through year-end in every state where you collect
6. Estimated taxes & carryovers
- Dates and amounts of every estimated tax payment made during the year — federal and state
- Last year's tax return, if you're working with a new preparer (carryovers live there)
Deadlines shift to the next business day when they fall on weekends or holidays — see our tax deadline calendar for the full schedule, and confirm specifics with your CPA.
Here's the quiet truth about this checklist: items 1 through 4 are simply what clean monthly bookkeeping produces automatically. When you outsource bookkeeping with InsightTrack, your year-end "prep" is us sending your CPA a reconciled set of books, the supporting schedules, and the 1099s we already issued — usually before they ask. Schedule a free consultation and make this the last year-end scramble.
