The accounting cycle is the repeating sequence a set of books runs through in every reporting period: identify and journalize each transaction, post it to the general ledger, prove the ledger balances on an unadjusted trial balance, book the adjusting entries, prove it balances again on an adjusted trial balance, prepare the financial statements, close the temporary accounts, and prove the close on a post-closing trial balance. What makes it a cycle rather than a checklist is the close at the end. Revenue and expense accounts are reduced to zero at the close while asset and liability balances carry forward, so the next period opens on a clean measure of performance and an unbroken measure of position.
The interval it runs over is the reporting period, and for a US taxpayer the annual period the books are kept on is the period the return is computed on. Taxable income is computed on the basis of the taxpayer’s taxable year, and the annual accounting period that defines that year is the annual period on the basis of which the taxpayer regularly computes his income in keeping his books (26 U.S.C. 441(a), (b) and (c)). Where a taxpayer keeps no books, or has no annual accounting period, or has one that does not qualify as a fiscal year, the taxable year is the calendar year by default (26 U.S.C. 441(g)). The books normally set the period, and where they do not, the statute sets it for them.
The Steps of the Accounting Cycle, in Order
The sequence falls into three phases, and every step belongs to one of them.
Record and post. A transaction enters the books when there is a source document behind it: an invoice, a receipt, a bank record. It is written first as a journal entry, the dated record naming the accounts and the amounts on each side, and then posted to the general ledger, the set of accounts where the balances actually accumulate. Both sides of the entry are written at once, the mechanism set out in bookkeeping and in double-entry bookkeeping.
Prove, adjust, prove again. The unadjusted trial balance lists every ledger account with its balance in a debit or a credit column and tests that the two totals agree, and what that test does and does not catch is in trial balance. The adjusting entries then move revenue and expense into the period each one was earned or incurred in, an accrual putting an amount on the books ahead of the cash and a deferral holding one that arrived early on the balance sheet until the period it belongs to, alongside depreciation and any correction the review turned up. The adjusted trial balance is the same listing run again once those entries are posted, and it is the version the statements are built from. Between the two some preparers lay out a worksheet, a working paper that sets the unadjusted balances, the adjustments and the adjusted balances in columns side by side. Nothing is posted from the worksheet itself. An adjustment exists in the books only once it has been journalized and posted like any other entry.
Report, close, prove the close. The adjusted balances are summarized into the financial statements, among them the income statement covering the period and the balance sheet reporting the position at its end, a split worked through in balance sheet vs income statement. The closing entries then reduce the temporary accounts to zero. The post-closing trial balance is the proof that they did, and its balances are the opening balances of the next period, which is the point at which the sequence starts again.
The sequence is stable. The number of steps it gets cut into is a teaching convention rather than anything a standard fixes, and presentations differ on whether the worksheet, the adjusted trial balance, the post-closing trial balance and the reversing entries are counted as steps of their own or folded into the ones around them. Reversing entries are the optional first-day entries of the following period that undo certain accruals so the next period’s routine posting runs without double counting.
What the Closing Entries Actually Do
Closing is the step that separates one reporting period from the next, and it is the step that gives the cycle its shape. The split behind it is set out in the IRS recordkeeping guidance for a double-entry system: income and expense accounts are closed at the end of each tax year, while asset, liability and net worth accounts stay open on a permanent basis (IRS Publication 583, Starting a Business and Keeping Records, Rev. December 2024). Net worth there is the excess of assets over liabilities. That is the temporary and permanent split, put as a duty a taxpayer’s records have to meet rather than as theory.
The closed balances are not deleted. They land in the equity account that carries the cumulative result, which is the one figure the two statements meet at, covered in balance sheet vs income statement and rolled forward in statement of retained earnings. What the closing step adds is the mechanics of getting them there.
Many ledgers run the transfer through an income summary account, a temporary account opened and emptied inside the close itself. On a period that ended in a profit, with fees earned and three expense accounts to clear, the entries run like this:
Fees earned 52,000
Income summary 52,000
Income summary 38,500
Salaries expense 26,000
Rent expense 7,500
Depreciation expense 5,000
Income summary 13,500
Retained earnings 13,500Fees earned, the three expense accounts and income summary all sit at zero once those entries are posted, and retained earnings has moved by the period’s result. A ledger that closes revenue and expense straight to retained earnings arrives at the same place without the holding account.
Where the Cycle Sits in a Firm’s Work
Inside a firm closing client books, the cycle is the unit of work that repeats, once per client per period, rather than a diagram. The assumption underneath it, that a business’s continuous life can be reported in intervals at all, is periodicity, and the interval a given client is held to is its fiscal year.
Not every client meets every step at the same frequency. A compliance-only client may see adjusting and closing entries once a year, while a client on a monthly close runs the recording, proving and reporting phase every month and still books the closing entries only at year end. The operational version of that work, who confirms what and in what order across a portfolio of client books, is in the month-end close checklist.
The practical reason the sequence is worth naming as a sequence is handoff. A preparer who stops at the adjusted trial balance and a reviewer who starts at the statements are working on the same period from two ends, and the step each of them owns has to be stated rather than assumed.
What the Accounting Cycle Is Not
The cash conversion cycle measures the days between paying for the inputs of a sale and collecting the cash from that sale, so it reads working capital rather than sequencing bookkeeping steps (cash conversion cycle).
The budget cycle runs on the same calendar in the other direction. It plans and approves what should happen in a period, while the accounting cycle records and reports what did.
An accounting period is the interval the cycle runs over rather than the cycle itself. The period sets the boundary, and the cycle is the work done inside it.
Common Questions
It depends on the numbering in front of you, because the numbering is not standardized. Where the sequence is cut into 8 steps, step 5 is usually the worksheet and the adjusting entries follow it. Where it is cut into 10, the worksheet is usually not counted and step 5 is the adjusting entries themselves. The order of the actual work is the same either way.
The 10-step version is the same sequence with intermediate stages broken out that shorter versions fold in: reviewing the adjusted trial balance, running the post-closing trial balance, and recording reversing entries at the start of the next period. It usually drops the worksheet, which is why it is not simply the 8-step list with two items added.
There is no standard 5-stage list. Presentations that use one collapse the same sequence into stages rather than steps, typically recording, posting, adjusting and proving, reporting, and closing, with the individual steps sitting inside those stages.
That question is usually reaching for transaction cycles rather than the accounting cycle. Transaction cycles group related transactions by the process that produces them, sales and collections, purchases and payments, payroll, and so on. They describe how a set of records is organized, not what happens to the books between one period end and the next.
Accountably places trained offshore accountants inside US CPA and EA firms, and a firm can run a block of its own close work through a trial task and have its own reviewer grade what comes back.
