The Records That Have to Exist Before December 31
Your bank statement proves money moved. It doesn't prove what it was for, and by February nobody can tell the difference.
There's a version of “my books are done” that isn't done at all. The transactions are categorized, the accounts reconcile, the profit and loss statement looks reasonable. Everything balances.
And then someone asks what a particular payment was for, or who a particular vendor is, or whether a large purchase was a repair or an improvement — and the answer is a shrug, because the number is in the books but the evidence never made it anywhere.
That gap is invisible all year. It becomes visible in February, when it's expensive.
November is the right month to look at this. Not because of a deadline, but because almost everything on the list below is easy to fix while the year is still open and difficult or impossible once it closes.
What a bank feed actually tells you
A bank feed is a fast, accurate record of money moving. That's genuinely valuable and it's why modern bookkeeping is faster than it used to be.
What it can't tell you is why. A $2,400 payment to a supplier is a fact. Whether it was materials for one client's project, a piece of equipment that should be treated differently, or a deposit on something that hasn't been delivered yet — that's context, and it doesn't come through the feed.
Most of the time the context is obvious when the transaction is recent and gone when it isn't. Which means the whole game is capturing it close to when it happened, not reconstructing it at the end.
The records that actually cause problems when they're missing
Not an exhaustive list — an honest one, based on what tends to be missing when someone hands over a year.
W-9s from anyone you paid for services. This is the one with a hard edge on it, because it depends on cooperation from someone else. In November, a request usually takes one email. In late January, from a subcontractor you haven't worked with since summer, it can take weeks and sometimes doesn't happen. Collect them from everyone who provided services, without pre-deciding who will need one — that determination isn't yours or mine to make, and the cost of having one you didn't need is zero.
Documentation for anything large or unusual. The ordinary recurring expenses take care of themselves. It's the one-off purchases, the big-ticket items, and the transactions that don't look like anything else in the account that generate questions later. If a payment would make someone stop and ask, the answer should be attached to it now.
Anything you bought that will last more than a year. Equipment, vehicles, major technology. These get treated differently from ordinary expenses, and how they're treated is your CPA's determination — but that determination needs the purchase documents, the date, and the actual amount. A line in the books that says “Equipment $8,400” with nothing behind it is a question, not an answer.
Loan and financing paperwork. If you borrowed, financed a vehicle, or took on any kind of payment plan, the agreement matters — the payments coming out of your account each month are part principal and part interest, and separating them correctly requires the document. Without it, the whole payment usually gets recorded as one thing, which is wrong in a way that compounds every month.
Records of money you moved to yourself. Owner draws and contributions should be identifiable as what they are. This is straightforward when there's a regular transfer with a consistent description and genuinely painful when it's forty irregular movements nobody labeled.
Vendor records that identify actual entities. Legal name and address, not a first name and a phone number. “Mike's guy” is not a vendor record, and in January it's a mystery.
Anything that ran through a personal account. These need to be identified and recorded before the year closes. They're not miscategorized — they're absent, which is harder to notice. (More on why this happens.)
What's still fixable in November, and what isn't
Worth being clear about which way each of these runs, because it changes what you do this month.
Still easy now:chasing W-9s, tracking down purchase documents for the year's large items, finding the loan agreement in your email, identifying personal-account payments while you still remember them, and asking your own questions about transactions that look odd.
Getting harder: anything that depends on someone else responding, and anything that depends on your memory of a specific transaction. Both degrade steadily, and both fall off a cliff in January when everyone is busy.
Effectively gone:the reason behind a small ambiguous transaction from eight months ago that nobody noted at the time. Some of these can be reconstructed from context and some genuinely can't, and the honest thing is to say so rather than to guess.
The practical implication: start with the items that depend on other people. Those have the longest lead time and the least control.
Where my job ends
I'm going to be direct about this, because the topic invites confusion.
What I don't do is tell you what's deductible, what documentation any particular rule requires, how an asset should be treated, or what your return needs. Those are your CPA's calls, they rest on rules that change, and a bookkeeper guessing at them is worse than useless.
What I do is make sure the record exists and that it's attached to the right transaction — so that when your preparer asks a question, the answer is already sitting there instead of being reconstructed under time pressure. The determination is theirs. The evidence is mine.
The difference matters more than it sounds. A preparer handed complete records makes decisions. A preparer handed incomplete records asks you questions, waits, and bills for the time — and in the meantime you're the one doing the searching.
A reasonable November
None of this needs to be a project. An hour with your own books, working down the list above, will tell you where you actually stand. Most owners find two or three gaps, not twenty, and most of those gaps are one email away from closed.
The ones that aren't — the missing loan document, the four vendors with no W-9, the eight months of payments that ran through a personal card — are exactly the ones worth knowing about now rather than discovering when someone else finds them.
At EMJ Advisors, this isn't a fourth-quarter scramble because the records get attached as the transactions happen, all year. Your CPA gets a complete file. You get a January that involves a signature rather than a search.
If you're not sure what's actually behind the numbers in your books, that's exactly the kind of thing one conversation will tell you — and November is a much better month for that conversation than February.
