Year-end bookkeeping: what has to be ready before December runs out

Before December runs out, what has to be ready is not the whole pile of paperwork, it is the number. A reconciled, trustworthy P&L through November is what lets you decide on equipment, vendor payments, bonuses, distributions and owner draws while there is still time. After December 31 those decisions are out of reach. What is left for January is checking and delivering: reconciling December 31, finishing contractor data and building the package your CPA receives. Tax calls stay with your CPA.

What you can still fix in December and what only gets fixed later

The line between the two lists is the date of the event. Anything that depends on money moving has to happen inside the year. Anything that depends only on recording, classifying or collecting a document can be fixed later, with the year already closed.

The left column is what is worth chasing now. The right one is scheduled work that does not expire on January 1.

The decisions that belong to the owner, and only to the owner

November and December bring a set of decisions nobody makes for the owner. Your CPA explains the tax effect of each one. Bookkeeping supplies the number that shows whether it fits. You are the one who signs.

• Buying equipment. It depends on knowing the year's result so far and how much cash is left to cross the weak months at the start of next year. A rushed purchase made with a stale P&L tends to become a payment due in February.
• Prepaying a vendor. It depends on accounts payable being in order. Prepaying without knowing what is already committed just swaps a December problem for a January one.
• Distributions. They depend on the Balance Sheet actually showing what belongs to the owner. If draws and company expenses sit in the same place, that number does not exist.
• Year-end bonuses. They depend on the real cost of payroll, taxes included, not on the gross wage you carry in your head. The loaded cost usually surprises.
• Owner draws. They depend on the company account and the personal account being separated in the ledger. Without that, you do not know how much you already took this year.

Why none of those decisions works on an estimated number

A P&L with unreconciled months is wrong in both directions, and never the way you expect. Expenses not yet recorded make profit look bigger. A deposit counted twice, or a transfer between accounts treated as revenue, inflates the result as well. Meanwhile an equipment purchase dumped into expenses without review can make a good month look bad.

The problem is not the error, it is when it shows up. By March, when your CPA finds it, the December decision is made and the money is gone.

The order in which each front has to close

Closing every front in parallel feels faster and is almost always slower, because each one depends on the previous one. This is the sequence that avoids redoing work.

• Bank and card first. Nothing above it stands if the system balance does not match the statement. Reconciliation is the foundation, not the last step.
• Then receivables and payables. This is where you find out what belongs to the year's result and what is money still in motion. An old open invoice is usually a forgotten collection or a payment already received and never applied.
• Payroll next. Payroll cost closes on a calendar that belongs to the provider, not to you. Bonuses and the last run of the year have to land before their cutoff.
• Contractors after payroll. A W-9 for each one, the total paid during the year, and what went out by card or payment platform, which the platform usually reports on a 1099-K.
• Assets and loans last inside the year. What was bought, with date, amount and receipt. Each loan balance checked with the lender, with interest split from principal.
• Only then the annual reports. The P&L and Balance Sheet close on top of a base that already ties out, and the package can go to your CPA.

Flip that order and the work comes back. Closing the P&L before reconciling the bank means closing it twice. The item by item list of what belongs in the package is in the year-end checklist, the companion piece to this article.

Why the package has to arrive in January, not in March

Your CPA does not start your work when the material arrives. They start when the queue allows. A package that arrives in March competes with everyone else who also ran late, and lands too close to the federal deadlines: March 15 for S corporations and partnerships, which includes multi member LLCs, and April 15 for individuals and calendar year C corporations. Filing an extension is their call, not your plan B.

January has a deadline of its own. The 1099-NEC is due January 31, with the next business day rule when the date falls on a weekend or holiday. The threshold was 600 dollars for payments through 2025 and rose to 2,000 dollars for payments made from 2026 on, indexed for inflation after that. Always confirm with your CPA which one applies to you.

Where bookkeeping ends and your CPA begins

The split is simple and worth repeating, because almost every year-end friction starts there. Bookkeeping records, reconciles and organizes: what happened, when, in which account, with which document. Your CPA reads that against the law: how an asset is treated, what the depreciation is, whether an extension makes sense, what each decision does to the tax bill. They are the ones who prepare and file.

GS Brasil does not prepare or file taxes. What it does is deliver the information early enough for your CPA to decide with time, and for you to decide with a number.

How to reach December without the scramble

Whoever closes every month arrives in November to review, not to rebuild. The full month by month scope of the annual close is on the year-end bookkeeping page. If you want the number on the table before the decision instead of after it, Financial Support Premium tracks cash projections and margins during the year, which is when these choices actually come up.
