Sundries in accounting are small, infrequent transactions that don’t warrant their own line in the chart of accounts, so they’re grouped under a single miscellaneous heading. The label keeps the books uncluttered while still capturing every dollar that moves through the business. Sundries can be income or expenses, and they can also represent small amounts owed to or by the business.
What Qualifies as a Sundry Transaction
A transaction is sundry when two things are true: it happens rarely, and the amount is small compared with the business’s overall activity. A replacement part for a seldom-serviced machine, a one-time permit fee, or a refund from a cancelled subscription all fit. None of them tells you anything meaningful about how the business normally operates.
The practical test is whether tracking the item separately would add more clutter than clarity. If it shows up once or twice a year and doesn’t move the financial picture, dropping it into a sundry account saves time and keeps reports readable. Once that stops being true, the item needs its own account.
The Four Types of Sundry Accounts
Sundry accounts split along two axes: money in or money out, and whether the balance is something the business owns or owes.
Sundry Income
One-time revenue that sits outside core operations. Selling an old office desk, earning a small amount of interest on a security deposit, or getting a refund from a vendor all count. These amounts appear on the income statement but don’t reflect what the business does day to day.
Sundry Expenses
Minor, irregular costs: a bank service charge, a small late-payment fee, the cost of replacing a broken office lock. Each is too small to influence a budget on its own, but the entries still belong in the books for accurate tax reporting.
Sundry Debtors
People or companies that owe the business small amounts from non-operating activity. A common example is an employee who made a personal long-distance call on a company phone and owes for the charge. These are assets because the business has a right to collect.
Sundry Creditors
The mirror image: parties the business owes for minor, non-inventory obligations, such as a balance due to a local contractor for a one-time repair. These are liabilities because the business still has to pay.
Where Sundries Appear on Financial Statements
On the income statement, sundry income usually falls under an “Other Income” heading below revenue from main operations. Sundry expenses appear in the operating expense section, typically near the bottom to signal their minor role. The placement keeps attention on the costs that actually drive the business.
On the balance sheet, sundry debtors sit within current assets because the business expects to collect within the year. Sundry creditors go under current liabilities on the same logic in reverse. Stakeholders get a quick read on total miscellaneous obligations without wading through every small entry.
Sundry Expenses vs. Petty Cash
People often blur these two, and the distinction matters. Petty cash is a physical stash of money set aside for small purchases. On the balance sheet, it’s a current asset and stays there until the fund is replenished, at which point the actual expenses paid from it get recorded in the general ledger under their proper categories.
Sundry expenses aren’t a pool of money at all. They’re a classification for transactions that don’t fit anywhere else. A coffee run paid from petty cash might eventually land in the sundry expense account, but the two ideas operate at different levels. Petty cash is about how you pay. Sundry is about how you categorize what you paid for.
The Materiality Principle Behind Sundry Accounts
Grouping small items into a single account rests on the accounting principle of materiality. Under Generally Accepted Accounting Principles, information is material if leaving it out or misstating it could change the decisions a reasonable person makes based on the financial statements. If a transaction is immaterial, there’s no need to break it out.
A widespread rule of thumb treats anything below 5% of pre-tax income as presumptively immaterial. The SEC has acknowledged this benchmark as a reasonable starting point, but its staff has made clear that no single percentage substitutes for judgment. A misstatement can be well under 5% and still be material if it masks a trend, turns a loss into a profit, or involves something like self-dealing by management. The FASB has taken the same position, rejecting calls to adopt a fixed numerical formula.1SEC. Staff Accounting Bulletin No. 99 – Materiality
In practice, sundry accounts are fine as long as the totals stay small enough that no reasonable investor or lender would care about the details. The moment a sundry category grows large enough to matter, it needs its own account with full disclosure.
Tax Reporting for Sundry Expenses
The IRS doesn’t use the word “sundry,” but it expects you to account for miscellaneous business costs. Where those costs go on your return depends on your business structure.
Sole Proprietorships on Schedule C
Miscellaneous expenses that don’t fit the named categories on Schedule C go on Line 48, with the total carrying to Line 27b. The IRS requires you to list the type and amount of each expense separately, not just report a lump sum. “Sundry expenses — $2,400” won’t do; you need “bank fees — $180, equipment repair — $620,” and so on.2Internal Revenue Service. Instructions for Schedule C (Form 1040) (2025)
For small equipment and supplies, the de minimis safe harbor lets you deduct tangible property costing $2,500 or less per item without capitalizing it, provided you don’t have an audited financial statement. If you do have one, the threshold rises to $5,000 per item. These items often pass through a sundry expense account in the books before being itemized on the return.3Internal Revenue Service. Tangible Property Final Regulations
Corporations on Form 1120
Corporations report miscellaneous deductions on Line 26 of Form 1120 and attach a statement listing each deduction by type and amount. Examples the IRS gives for this line include insurance premiums, legal fees, supplies, utilities, and travel expenses not claimed elsewhere.4Internal Revenue Service. 2025 Instructions for Form 1120 – U.S. Corporation Income Tax Return
What You Cannot Deduct
Some costs that businesses mistakenly bury in sundry accounts are flatly non-deductible. Political contributions, lobbying expenses, club dues for social or recreational organizations, fines, and penalties paid to a government agency cannot be written off, regardless of how you categorize them. Parking tickets, tax penalties, and settlements for civil or criminal violations all fall in this bucket.5Internal Revenue Service. Publication 529 – Miscellaneous Deductions
Hiding a non-deductible expense inside a sundry account doesn’t make it invisible to the IRS. If audited, the accuracy-related penalty for negligence is 20% of the underpaid tax attributable to the error.6Internal Revenue Service. Accuracy-Related Penalty
Audit Risk and Internal Controls
Sundry accounts are where fraud likes to hide. Because the category is inherently vague, it’s easier for someone to slip a personal charge or fabricated expense into a bucket labeled “miscellaneous” than into a tightly defined account like payroll or rent. Auditors know this and give sundry accounts more scrutiny than most other line items.
A few controls keep these accounts clean:
- Require an itemized, original receipt showing the date, amount, and business purpose for every entry. No receipt, no reimbursement.
- Separate duties so the person who approves a sundry expense is not the person who records it or signs the check.
- Set an internal dollar cap on total sundry spending per period, with mandatory review by someone with authority before the balance can grow further.
- Lock down petty cash: limit access, require receipts before replenishment, and reconcile the balance at least monthly.
The IRS also notices when miscellaneous deductions look out of scale for the type of business. A return showing expenses 20% or more above industry norms for a category invites a second look. Lean, well-documented sundry accounts are the best defense.
When to Reclassify a Sundry Account
Sundry accounts are meant to be temporary homes, not permanent ones. If the same type of transaction keeps showing up, it’s no longer a stray. A monthly review is the simplest way to catch items that have outgrown the category.
Two signals that an item deserves its own account: the same type of expense or income appears three or more times in a quarter, or the total for a single type of sundry item starts representing a noticeable share of its parent category. When either happens, create a dedicated account, move future transactions there, and update the chart of accounts. The reclassification itself is a straightforward journal entry; the harder part is reviewing often enough to catch the pattern before it spreads across several reporting periods.
