Year-end bookkeeping checklist for Idaho small businesses

December and January are when sloppy books finally cost you. A miscategorized expense, an account that never got reconciled, or a 1099 you forgot to send turns into a scramble in March, and your tax preparer ends up billing you to untangle it.

Year-end is your chance to catch all of that while it's still easy to fix. The goal is simple. Hand your CPA or tax preparer a clean, reconciled set of books so they can do their job fast and accurately, without guessing.

Here's the full checklist, in the order we run it, with timing so nothing slips. Most of it can be done in the first ten days after the year closes, the same way we close every month by the 10th.

Start here, because almost everything else depends on it. Reconcile each bank account, credit card, and loan against the real December statement. Your books should match the money that moved, down to the penny.

Reconciling now catches duplicates, missing transactions, and bank errors while they're easy to fix. Wait until April and you're rebuilding a year of history under a deadline.

If an account hasn't been reconciled in months, that's your first job. Work backward statement by statement until your ending balances match. For QuickBooks Online users, the reconciliation tool flags any discrepancy so you know exactly where the books and the bank disagree.

Practical step: pull the December statement for every account, reconcile each one, and confirm the ending balance in your books matches the statement before you move on.

Once accounts are reconciled, scan how transactions are coded. Owner draws sitting in expenses, personal charges mixed with business, vague "Ask My Accountant" or uncategorized buckets: these are the items that distort your profit and loss and slow your tax preparer down. Run a full-year profit and loss, read it line by line, and move misfiled transactions to the right account.

Payroll has hard deadlines and real penalties, so give it attention early. Confirm that every employee's wages, withholding, and benefits are recorded correctly, and that your Idaho state withholding and unemployment insurance amounts tie out for the year. New employers in Idaho pay an unemployment insurance rate of 1.0% through the Department of Labor.

For W-2s, verify each employee's legal name, Social Security number, and address before forms go out. For contractors, pull together a W-9 for anyone you paid during the year and confirm their name, address, and taxpayer ID so their 1099 is accurate. Missing W-9s are the most common reason 1099s get held up, so chase them down now rather than in late January.

Practical step: clear your uncategorized buckets to zero, reconcile your payroll totals for the year, verify W-2 details for every employee, and collect a current W-9 for each contractor who needs a 1099.

Your tax preparer needs an accurate picture of what you own and what's on the shelf. Make a list of any equipment, vehicles, or other fixed assets you bought, sold, or disposed of during the year, with the dates and amounts. That's the information your CPA uses to handle depreciation correctly.

If you carry inventory, count it. A physical year-end count gives you a real ending inventory number instead of an estimate, and it surfaces shrinkage or counting errors you'll want to catch before the books close.

Practical step: update your fixed asset list with anything bought or sold this year, and complete a physical inventory count so your ending inventory figure is real, not a guess. Leave the actual depreciation method and asset write-offs to your CPA.

If you sell taxable goods or services, reconcile what you collected against what you filed. Idaho's state sales and use tax is 6%. Most businesses file monthly, due the 20th of the following month, and you can file quarterly if you owe under $750 a quarter. Either way, you file even on a zero-sales period.

Don't forget use tax. If you bought equipment or supplies out of state or online and used them here in Idaho without paying sales tax, you owe 6% use tax on those purchases. Year-end is the time to review online and out-of-state buys and make sure use tax was recorded.

If you sell in a resort city such as Driggs, Victor, Swan Valley, or Irwin, those areas add a local-option tax on top of the state rate. Confirm you collected and reported the local piece correctly for any sales there.

Practical step: match your collected sales tax to your filed returns for every period, record use tax on any untaxed out-of-state or online purchases, and confirm resort-city local-option tax is handled if it applies to you.

Once everything above ties out, lock the year so the numbers don't shift after you've handed them off. Then give your CPA or tax preparer a tidy package: a year-end profit and loss, balance sheet, reconciliation reports, your fixed asset list, ending inventory, and payroll and contractor totals.

Clean books mean your tax preparer spends their time on tax strategy and filing, not on fixing your records. That usually means a faster turnaround and a smaller bill.

Tidy Ledgers handles the bookkeeping side of all of this and works alongside your CPA or tax preparer. We don't file your income tax return, and entity or legal questions belong with a CPA, attorney, or the relevant Idaho agency. What we do is get the books accurate, reconciled, and ready to hand off.

Run the checklist in order: reconcile accounts and review categories by early January, confirm payroll and collect W-9s by mid-January, update assets and count inventory by mid-January, square up sales and use tax by your filing due date, then lock the year and send the package.
