Why does the payroll clearing account not return to zero, and what is stuck in it?

A waiting room for net pay, and a separate account for each amount you hold

When you record a payroll, the net pay for your staff goes into a waiting room in your books. When the bank pays your staff, the same amount leaves the waiting room. So after each pay run, the waiting room is empty again. Accountants call it the payroll clearing account.

So each payroll account has a correct shape. The clearing account must return to nil after each run. A tax account must hold about one month of taxes if you pay monthly. If an amount stays when it should leave, a payment did not occur, or an entry is wrong.

4,023.40 in Northbrook's clearing account, from five items

Northbrook pays its staff on the last business day of each month. A payroll provider calculates the pay. On Monday 19 October, the owner runs the skill for September 2026. The skill reads twelve months of entries on the clearing account, 2200, to Wednesday 30 September. Normal pay runs leave nothing. These movements did not net to nil:

The skill then sorts the 4,023.40 by age, in months before September. It ages each item from the run or entry that its memo names. Where a memo names nothing, it uses the oldest first, and it states which method it used.

1,800 + 0 + 1,560 + 663.40 = 4,023.40. Four items are older than 60 days, the skill's limit for a clearing account. The skill reports them as a total first: 2,223.40 in four items, more than 60 days in payroll clearing. The oldest is from before October 2025. JE-0912 is only 6 days old. The skill still lists it, because a manual entry with no payroll run behind it does not belong in this account.

The owner's question, in one line: 2200 does not return to zero because 4,023.40 of five items never left it. Two are unpaid wages that people own (1,050.00). One is a disputed final pay (1,150.00). One is an entry with no pay run behind it (1,800.00). The last 23.40 has no known origin.

A month that looks explained, on top of 2,223.40 that nobody explained

The usual monthly check compares the account with last month. The balance went from 2,223.40 to 4,023.40, and JE-0912 explains the 1,800. The skill uses a different test. A clearing account must be nil after the run, so it compares the balance with nil.

The skill also finds the lowest point of the balance in twelve months. At Northbrook that is 23.40. It is the part that never cleared at any time. The other 4,000.00 came into the account inside the twelve months, so the lowest point cannot show it. The age bands and the 60-day test show it. The skill reports all three results before any other work.

The federal tax account agrees with the books, and it holds two months

The same tests apply to each account for amounts that you hold for others. A tax account that you pay monthly must hold about one month of taxes at a month end. Northbrook deposits federal taxes monthly, by the 15th of the next month. If the 15th is not a business day, the deadline moves to the next business day². Under Publication 15 (2026), an employer is a monthly depositor if its taxes for a lookback period were $50,000 or less².

The roll-forward of 2210 gives a difference of zero, so the account looks reconciled. The skill does not accept a zero difference as proof. The expected figure came from the same entries as the books, so the zero proves only the arithmetic. The behaviour test shows the problem: the account grew, and it did not drop in September. The September 14,400 is not due until Thursday 15 October. The skill documents it as timing and proposes no correction for it.

The 12,600 is only 30 days old on 30 September, so the age test does not catch it yet. The behaviour test does. The full tie-out of the register to the books and the bank belongs to a different skill, payroll reconciliation. Part of the 12,600 is money that Northbrook took from its staff's pay. In the US, a person who must pay that money and willfully does not pay it can be personally liable³. This page is not legal advice.

Unclaimed pay stays a debt to a person

An easy correction is to write off the whole 4,023.40 so that the account shows zero. The skill refuses that. 1,050.00 of it is pay that two people own: the deposit that came back (640) and the check that nobody cashed (410). That money belongs to the employee until it belongs to the state. For example, in California, payroll and wages become unclaimed property after one year, and a business that holds unclaimed property must report it each year⁴. Other states have different periods and rules. Before a report, California expects the holder to send a letter to the owner's last address⁵.

An account for amounts you owe goes down only when you pay them, or when the creditor releases you. So the skill never writes off a tax or benefit balance without a statement from the authority or provider. A small write-off is a one-time step. If the same small write-off occurs each month, the skill reports it as a fault in the process.

Eight items, in one message

The skill asks these first, in one short batch. It asks only for what it cannot already see. Items E, F and H are requests for files.

1. Use MosoFin for this run, or upload the data yourself?
   MosoFin is the connection to your books and the other platforms that you link. With it, the skill reads from there. Without it, you upload the files, and the checks are the same. It asks only if your account has the MosoFin tools.
2. Which company, and which payroll accounts: clearing, suspense, and each account for amounts that you hold or owe?
   It does one reconciliation for each account, and each company has its own clearing account. On the MosoFin path, it shows the payroll accounts from your chart, and you approve the list. It never picks a company for you.
3. Which period?
   Required. Every read and every roll-forward uses it.
4. How often do you pay each amount that you hold: monthly, twice a week, each quarter?
   Required. The correct balance of each account depends on it. The skill never guesses it. Without it, the behaviour test has nothing to compare with.
5. Please give the payroll register for the period.
   Required. The register is the report from your payroll software, and it shows what each run owed. If you cannot give it, the skill uses your payroll entries in its place and says so. Then the result proves only that the account moved as the entries say.
6. Please give the bank statement for the period.
   The statement proves that the money left. Without it, the skill compares with the payments in your books and says so.
7. What is your limit for a write-off, and who approves one?
   The limit separates a small leftover from one that needs a correction. The skill never sets a write-off for you.
8. If you want a balance cleared, please give the statement of account from the tax authority, pension or benefit provider.
   Recommended, and required before any write-off on those accounts. A leftover on them is usually a payment to make or a refund to claim.

Northbrook's owner uploaded the files. The owner gave a limit of 50.00 and approves each write-off. The skill found one more account with payroll entries, 2250 Accrued payroll, and asked about it. The owner reviews 2250 with the month-end accruals, so the workpaper names it as excluded, with that reason. Then the skill reads the plan back and waits for a yes. The skill's own sample is for a UK company. For this US example, it reads like this:

"Reconciling the payroll control accounts of Northbrook Trading for September 2026 (payroll clearing 2200, federal payroll taxes 2210, 401(k) 2230 and state unemployment 2240) from the files you uploaded: GL detail for the last twelve months, trial balances at 31 August and 30 September, the September payroll register, the remittance records and the September bank statement. The accrual side uses the register. Federal taxes remitted monthly by the 15th, 401(k) monthly by the 7th, state unemployment quarterly. The bank tie-out is to the bank statement. Shall I go ahead?"

It never repeats one person's line back to you.

Connect your books, or upload seven items

This was Northbrook's first run, so no earlier reconciliation existed. The workpaper says so and takes the start balance from the trial balance at 31 August. Net pay agreed with the bank statement on both September pay dates: 4,200.00 on 15 September and 36,600.00 on 30 September.

A workpaper with nine sheets

The summary has lines for the preparer and the reviewer, and the answer ends with a Data sources line. The skill asks before it makes an Excel file, Payroll_Recs_2026-09_Northbrook Trading.xlsx. If you say no, you get the same sheets as tables in the chat. After you approve the results, it offers to save your rules for the next run: account list, payment schedules, payroll calendar, write-off limit and payees. It never saves balances, ages, open items or anybody's pay.

Other jobs go to other skills. payroll-reconciliation does the full tie-out of the register to the books and the bank. journal-entry-builder builds the proposed entries. payroll-journal-entry-builder builds the payroll entry itself.

Seven terms, in plain English

Payroll clearing account

A waiting room in your books between "payroll recorded" and "payroll paid". It must return to nil after each pay run.

Payroll control account

Any account that holds a payroll amount until you pay it: clearing, taxes, 401(k) or pension, and court orders. Your books show each one as a payable¹.

Withholding

Money that you take from pay for somebody else, for example tax or a 401(k). It is never the employer's money³.

Remittance schedule

How often you must pay a withholding to its owner. The authority sets it, and it decides the correct balance of the account².

Stale balance

An amount that stays in a payroll account long after it should leave. For a clearing account, the skill uses 60 days.

Never-clearing residual

The lowest point that the balance reached in twelve months. It is the part that never left at any time.

Unclaimed pay, and escheatment

Pay that a person did not collect stays theirs. After a period in the law of the state, the holder reports it and gives it to the state⁴.

Where the facts on this page come from

The sources are an accounting textbook, two IRS pages and two pages from the California State Controller's Office. We found each one on 28 October 2026 in search results. We did not open the pages, so follow each link for today's wording. What the skill does comes from the skill's own files.

1. OpenStax: Principles of Accounting, Volume 1, 12.5 Record Transactions Incurred in Preparing PayrollWhen a company pays wages that it owes, the payable goes down and so does cash. Payroll taxes, benefits and deductions follow the same pattern: they stay payables until the company pays them.
2. IRS (US): Publication 15 (2026), (Circular E), Employer's Tax GuideThe deposit schedule comes from a lookback period. In the 2026 edition, $50,000 or less makes a monthly depositor. A monthly depositor deposits by the 15th of the next month, or the next business day.
3. IRS (US): Employment taxes and the Trust Fund Recovery Penalty (TFRP)A person who must pay the taxes withheld from employees, and willfully does not pay them, can be personally liable. This is a US rule.
4. California State Controller's Office (US, one state): Unclaimed Property, Holder Reporting, Frequently Asked QuestionsIn California, payroll, wages and commissions become unclaimed after one year, and most other property after three years. A business that holds unclaimed property reports it each year. Other states have different periods and rules.
5. California State Controller's Office (US, one state): Holder Due DiligenceBefore a report, the holder sends a letter to the owner's address on record for property of $50 or more. If the owner replies, the holder pays the owner and does not give the property to the state.

No outside authority backs the age bands, the 60-day limit, the lowest-point test, the nine causes, the workpaper sheets or the order of the work. They are the skill's own rules. We made up Northbrook Trading and every figure in the example for this page. Every tax figure in it comes from Northbrook's payroll provider report. The page states no tax rate, no wage cap and no unclaimed property period for Northbrook.
