The Year-End Handoff: Books Your Preparer Can Actually Use

TLDR

A preparer does not file from your Profit and Loss. They file from a balance sheet that ties out, because that is where the errors hide and where the return’s carryover figures come from. Before you send anything: reconcile every account through December, clear the suspense accounts, prove owner draws and loans, tie payroll to the W-3, and write down the handful of judgment calls you made. Doing this in January costs a fraction of what it costs in April.

Every January the same conversation happens. An owner sends over a Profit and Loss, the preparer asks four questions, and it takes three weeks to answer them because the answers were never written down.

None of that delay is about the P&L. The P&L is usually fine. The problems live on the balance sheet and in the decisions nobody documented.

#Why the balance sheet is the real deliverable

The Profit and Loss tells you what happened. The balance sheet tells you whether the P&L is trustworthy.

If cash on the balance sheet does not equal the bank, revenue and expenses cannot be right either, because every transaction touches both statements. An unexplained balance in a clearing account is unrecognized income or an unrecorded expense sitting in plain view. Negative inventory, a payroll liability that never clears, a loan balance that does not match the lender’s statement: each one is a P&L error wearing a different hat.

Preparers also need the balance sheet for the return itself. Depending on the entity, the return carries balance sheet detail, and basis, loans and equity accounts drive real tax outcomes. An owner draw miscoded as an expense is not a bookkeeping nitpick; it changes taxable income.

#What to reconcile before you send anything

Every bank and credit card account, through December. Against statements, not the feed. If an account is missing a month, say so rather than letting it be discovered.

Loans, against the lender’s year-end statement. The balance should tie, and the year’s payments should split into principal and interest correctly. Booking a whole payment as expense overstates your deduction, which is the wrong error to have.

Payroll, against the W-3 and the quarterly filings. Wages in the books should agree with what was reported. When they disagree, the filings are usually right and the books are wrong, and that gap becomes a notice later.

Sales tax collected versus remitted. The liability should clear. A growing balance means you are collecting and not remitting, and that is a problem with its own deadline.

Owner draws and contributions. These belong in equity, not income or expense. This is the single most common miscoding I see, and it moves taxable income directly.

#Clear the suspense accounts

Whatever your software calls it: Uncategorized, Ask My Accountant, Suspense. It should be empty at year end, and it usually is not.

Everything in there is a transaction nobody could identify. Left alone, one of two things happens: it gets guessed at, or it gets excluded. A guess becomes a deduction you cannot support. An exclusion means your books do not tie to the bank, which puts you back at the first problem.

Emptying it is mechanical but not always quick, because the answers live with you rather than with the bookkeeper. Ten minutes with a list of twelve transactions in January is worth several emails in April.

#Write down the judgment calls

This is the step almost nobody does and it removes most of the back-and-forth.

For the year, note in one place:

Anything unusual. An asset sale, a new loan, an insurance settlement, a large refund, a related-party transaction. Preparers do not need it explained beautifully. They need to know it happened, because these are the items with special treatment.
Fixed asset purchases, with dates and amounts, and whether the item was placed in service. The date matters more than the invoice date for depreciation, and only you know when the equipment actually started being used.
Anything you were unsure about. If you guessed at a category, say which. A flagged guess costs a moment to correct. An unflagged one gets relied on.
Personal-use items. The vehicle, the phone, the home office. If personal use has not been split out, say so, because the preparer has to know whether that adjustment still needs making.

#What to actually send

A trial balance or a balance sheet and P&L for the full year
The general ledger for the year, or access to the books
Year-end statements for every bank, card and loan account
Payroll reports, including the W-3 and quarterly filings
Fixed asset detail with purchase dates and amounts
1099s you issued and any you received
Your notes from the section above
Last year’s filed return, if the preparer does not already have it

Send it once and completely. Sending a P&L first, then a balance sheet on request, then statements a week later is how a return that takes an afternoon becomes a month.

#The version of this that is not painful

Everything above is easy if the books were closed monthly and miserable if they were not. That is the entire argument for a monthly close: twelve small reconciliations that each take a short time while the details are fresh, instead of one reconstruction in January where you are trying to remember a transaction from March.

If you are reading this in January and the books were not closed monthly, the order is still the same. Start with reconciliation, because nothing else can be trusted until cash is proven, and work forward from there.

If you are handing off to a new preparer this year, there is a separate set of things worth doing so nothing falls between the old firm and the new one. That is covered in switching accountants cleanly.
