Behind on your books? A catch-up bookkeeping checklist

If your books are a few months behind, or you genuinely can't remember the last time you reconciled an account, this is the most ordinary thing we see. Receipts pile up, the bank feed gets messy, a busy season swallows a quarter, and suddenly last year is a guessing game. It happens to careful, hardworking owners all the time.

The good news is that catch-up work follows a predictable order. You don't have to fix everything at once, and you don't have to feel bad about where things stand. Work the steps below one at a time and the pile gets smaller every session.

If you'd rather not do it alone, that's fine too. Read through the checklist so you know what's involved, then decide how much you want to hand off.

Here's the sequence we follow when we clean up a backlog. Do them in this order. Each step makes the next one easier, and skipping ahead usually means redoing work later. The sections after this one walk through the steps that trip people up most.

Catch-up work falls apart when you start categorizing before you have the full picture. Pull every statement for your whole window first: checking, savings, each credit card, lines of credit, term loans, and every payment processor you use. Save them as PDFs in one folder by account and month. A live bank login only goes back so far, and the day you lose access mid-cleanup is the day you'll wish you'd downloaded them. If a statement is missing, request it from the bank now so it's ready when you need it.

Next, deal with mixed accounts, one of the biggest reasons books drift out of accuracy. Mark anything personal that ran through the business, and anything business you paid from a personal card. Personal spending out of a business account is usually an owner draw, and business spending out of your own pocket is usually an owner contribution or a reimbursement. Labeling these correctly keeps your expenses honest and saves your tax preparer from sorting it out in April.

Going forward, a dedicated business checking account and card makes every future month faster to close. If a separate account also raises questions about how your business is set up, that's a conversation for your CPA or attorney, not something to settle inside your bookkeeping.

Reconciliation is the heart of catch-up work. It's how you prove your books match the money that moved instead of hoping they do. Start with the oldest month and the oldest account, match each transaction to the statement, and confirm the ending balance ties out before moving forward. Working oldest to newest matters, because an error in January quietly throws off every month after it. Fix it once at the source and the rest falls into line. Watch for duplicate entries, deposits that never landed in your books, and bank fees you forgot about.

Once each account ties out, clean up where everything landed. Backlogs are full of transactions parked in 'Uncategorized' or dumped into a catch-all bucket, and that makes your profit and loss close to useless for decisions or taxes. Recode each transaction to the right account: real expense categories, income, transfers between your own accounts, owner draws, and the principal-versus-interest split on loan payments. Transfers and owner draws are common trouble spots, since miscoding them can inflate your income or expenses for no reason.

When you're done, your profit and loss should read like a true story of the period. If a category looks surprisingly high or low, that's a clue to go back and check it before you call this step finished.

If you sell taxable goods or services, reconcile sales tax for every filing period in your catch-up window. Idaho's state sales and use tax rate is 6%. A few resort cities, including Driggs, Victor, Swan Valley, and Irwin, add a local-option tax on top, so check whether you sell in those places. Most businesses file Idaho sales tax monthly, due the 20th of the following month. If you owe under $750 in a quarter, you may file quarterly instead. Either way, file every period even when you had zero sales, because a skipped zero-sales filing still counts as a missing return.

Don't forget use tax. If you bought items from out of state or online and used them in Idaho without paying sales tax, you owe 6% use tax on those purchases. Match what you collected and what you owe against your reconciled books for each period.

If you have employees, your payroll records need to match your books too. Confirm wages, the taxes you withheld, and any reports you owe are accounted for. Idaho withholding runs through the State Tax Commission, and unemployment insurance runs through the Department of Labor, with a 1.0% new-employer rate. Both are set up through Idaho Business Registration along with your sales tax permit. For deadlines you've already missed or questions about penalties, the Idaho State Tax Commission is the authority, and your CPA can advise on how to handle past-due periods.

With accounts reconciled, categories fixed, and sales tax and payroll squared away, run a fresh profit and loss and balance sheet for the full window. Read them with a skeptical eye. Anything that looks off is easier to fix now than after your return is filed. Then hand the clean numbers to your CPA or tax preparer. We keep books accurate and tax-ready and work alongside your tax preparer, but we don't prepare income tax returns, so the actual filing stays with them.

The last step is staying caught up. Once your backlog is current, the easiest path is a steady monthly routine, with books closed by the 10th of the following month, so you never have to do this big a cleanup again. That's the real payoff: knowing where you stand without dreading it.
