A year end bookkeeping checklist confirms that every account has twelve statements, every month balances to its closing balance, no transaction is left uncategorized, and the files the CPA needs are in one place. Work through it per client, in that order, because each step depends on the one before.
What should a year end bookkeeping checklist confirm?
A year end bookkeeping checklist should confirm that the books are complete, accurate and explained. Complete means every account and month is present. Accurate means each balance ties to the bank. Explained means open questions have an answer or a written note. The CPA can then work from the file without coming back to you.
Use the table below for each client. The statuses and notes are examples of how to fill it in.
| Check | What done looks like | Example note |
|---|---|---|
| Account list is complete | Every bank, card and loan account the client had in the year is in the books | Savings account opened in June, added |
| Twelve statements per account | A statement for every month of the year, or the months the account was open | Checking: 12 of 12 |
| Each month balances | Opening balance plus transactions equals closing balance, every month | Card account off by 40.00 in August, fixed |
| Year start and end balances tie | January opening balance equals last year's December closing balance | Matches prior year file |
| Nothing uncategorized | The uncategorized account is zero | 3 lines cleared with client answers |
| Transfers net to zero | Transfers and card payments between the client's own accounts cancel out | Clearing account at 0.00 |
| Personal charges separated | Personal spending is in owner's draw or a similar account, not in expenses | 6 charges moved |
| Review items cleared | No line is waiting in a review queue | Queue empty |
| Open questions listed | Anything unresolved is written down for the CPA | 2 unknown deposits noted |
| Handover package ready | Reports, statements and notes in one folder, named clearly | See folder list below |
Order matters
Run the checks top to bottom. A missing statement makes a balance check meaningless, and an unbalanced month makes categorization risky, because you may be coding a line that should not exist. Fix problems at the earliest step where they appear.
Who the checklist is for
The checklist serves the bookkeeper first. Its second reader is the CPA, who will ask the same questions. A bookkeeper who answers them before being asked saves a round of emails and usually saves the client money.
Counting twelve statements per account before year end
Counting statements means building a grid with one row per account and one column per month, and marking each cell as in, missing or not applicable. The grid shows gaps at a glance, and one missing statement is enough to stop a year end file from closing.
A statement count grid
The example below shows one client with three accounts. The marks are made up for illustration: a tick means the statement is in and balanced, a dash means the account was not open, and MISSING means the statement has not arrived.
| Account | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec | Count |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Checking 4417 | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | 12 of 12 |
| Business card 9032 | ✓ | ✓ | ✓ | MISSING | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | 11 of 12 |
| Savings 8821 | – | – | – | – | – | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | 7 of 7 |
In this example the card account has one gap in April. The savings account shows seven of seven, because it opened in June, which is a complete set. You read the count column last: it tells you whether you are done, and the cells tell you where to look.
How to build the grid
- List every account from last year's file, then add any account the client opened during the year. Ask the client directly about new accounts; they rarely mention them.
- For each account, check the bank or card statement for the statement period, not only the file name. A file called "March" may cover February 14 to March 13.
- Mark a month in only if the statement is there and its balance check passes.
- Compare the first statement's opening balance with last year's closing balance for that account.
- Count the ticks per account and write the result in the count column.
Statement periods that do not match months
Many card statements close mid-month, so twelve statements may run from the 15th to the 14th. Count them by closing date and make sure the last one reaches the year end. If a card closes on the 14th, December 15 to 31 sits on the January statement, and you need that statement to finish the year. The post on credit card statement periods and posting dates explains how to post those.
Closed accounts
An account the client closed during the year still needs its statements, up to and including the final one that shows a zero balance. Ask for the closing statement; banks often send it as a last paper or portal download.
Year end items to hand the client's CPA
Hand the CPA a package they can use without a call: the year's reports, the balanced statements behind them, a list of open questions, and a note on anything unusual. Include what you did, not only what you found, so they know what has been checked.
A handover folder
A tidy folder beats a pile of attachments. Example contents:
- Reports: profit and loss, balance sheet and general ledger for the year, as exports or PDFs.
- Reconciliations: one balanced statement summary per account, with the opening and closing balances.
- The statements: all twelve for each account, named with the same pattern.
- A transfers and personal charges note: what was treated as a transfer and what was moved to owner's draw.
- An open items list: unknown deposits, missing receipts and questions the client has not answered.
- A change log: corrections you made after the client first sent their records.
Write a short cover note
Keep it to a page. State the period, list the accounts covered, say which months balanced and which did not, and name the unresolved items. If you made a judgment call, such as coding a deposit as owner contribution because the client said so, write down who told you and when. The CPA then knows which numbers rest on documents and which rest on the client's word.
Sharing the files safely
The package holds statements with account numbers and balances, so send it through a channel you trust, not as a loose email attachment. The rules for sharing a client's files with their CPA confidentially cover access and clean-up.
Ask what the CPA wants
CPAs differ. Some want a general ledger export, some want the trial balance in a spreadsheet, and some want to log in to the client's accounting file. Ask once at the start of the year and note the answer in the client's record. It saves a rebuild in January.
What if a year end statement is missing?
If a year end statement is missing, request it before you do anything else, because every later check depends on it. The bank can issue copies of past statements, and the client can usually download them. Meanwhile, work on the rest of the books and mark the gap.
Where to get it
Try these in order:
- The client's online banking portal, which usually keeps statements for a period of time.
- The bank's branch or phone support, for copies of older statements.
- The client's email, where e-statement notices and PDFs often land.
- The client's paper files, if the account still sends them.
If you cannot get it today
You can still estimate where the gap sits. The previous statement's closing balance and the next statement's opening balance bracket the missing month. The difference between them is the net activity you need to explain. List that figure in your open items list and tell the CPA clearly that the month is unsupported.
Avoid filling the gap with a plug entry. A plug hides the problem and can pass the balance check without being true. A missing month with a note is better than a made-up month.
Catching up when several are missing
When more than one month is missing, treat it as a backlog. Collect the statements, convert them together and balance each month in sequence. The plan in the guide to catching up bookkeeping from bank statements covers that, and a batch converter helps here: AutoBankConvert accepts a folder of statements across months and holds back any statement that fails its balance check, which points straight at the month that needs attention.
Year end bookkeeping started too late in January
When year end work starts late in January, cut the checklist to what the CPA cannot do without: statements for every account, balances that tie, and a list of open items. Everything else can follow. A late start calls for triage, not for skipping the checks.
What to do first
Order the work by risk:
- Build the statement count grid for every client and send the missing-statement requests the same day.
- Convert and balance what you have, and note every month that does not tie.
- Clear uncategorized lines for the largest accounts first.
- Send the CPA a partial package with the open items list, rather than waiting to send a perfect one.
Be honest about the status
Tell the CPA and the client what is done and what is not. A package marked "March to December balanced, January and February awaiting statements" is useful. A package that says nothing and has a gap is a surprise later.
Make next year easier
Late starts usually trace back to late statements. Build the count grid at the start of the year and update it monthly, and the January scramble shrinks to one final check. If your monthly close already confirms a balanced statement for each account, the year end is mostly a matter of adding up what you already did.
For clients you are processing in bulk, AutoBankConvert lets you convert a month of statements for all of them in one upload, which keeps the grid current without extra typing.
