Sundry expenses are the small, irregular costs a business incurs that don’t fit any standard expense category on the books. Think of them as an accounting junk drawer: a one-time wire transfer fee, a replacement power strip, a certified letter. Each cost is too small to matter on its own and none of them recur often enough to justify a permanent line item. The real skill isn’t recording them. It’s knowing when something has outgrown the label.
What Qualifies as a Sundry Expense
An expense belongs in the sundry category when it passes two tests. The dollar amount is immaterial relative to your total spending, and the cost is infrequent or nonrecurring. Fail either test and the expense probably deserves its own account. Monthly software fees are small but recurring, so they get a dedicated line. A one-time equipment rental might be large enough to track separately even though it only happens once.
Materiality is the accounting principle that makes this judgment call possible, and the Financial Accounting Standards Board is explicit that no fixed percentage applies to every business. Materiality is “an entity-specific aspect of relevance based on the nature or magnitude or both of the items,” and “no general standards of materiality could be formulated to take into account all the considerations that enter into” a reasonable judgment.1Financial Accounting Standards Board. Amendments to Statement of Financial Accounting Concepts No. 8 – Conceptual Framework for Financial Reporting Chapter 3 A $400 charge that barely registers for a company with $10 million in revenue could be a significant line item for a freelancer earning $60,000.
Common Examples
The costs that end up in a sundry account tend to be forgettable on their own, which is exactly why they get grouped. Typical examples include:
- A one-time bank service charge, such as a wire transfer fee or a cashier’s check fee that falls outside your normal banking relationship.
- Occasional postage, like sending a certified letter or a one-off package that doesn’t fall under a regular shipping contract.
- Minor repairs. Fixing a broken office chair, replacing a surge protector, getting a key copied.
- Small, infrequent charitable donations at a community event, provided your business doesn’t donate regularly enough to warrant its own account.
- Miscellaneous supplies bought outside your normal cycle: a whiteboard marker set, a replacement phone charger, cleaning supplies.
None of these items tells a useful story on its own line. Grouped under a sundry heading, they stay visible without cluttering your chart of accounts.
Where Sundry Expenses Show Up in Your Books
Sundry expenses are recorded in the general ledger as operating expenses. On the income statement, they appear as a single line, sometimes labeled “Sundry Expenses,” sometimes “Miscellaneous Expenses,” sometimes “Other Operating Expenses.” The total reduces gross profit on the way to net income, like any other operating cost.
Publicly traded companies face strict disaggregation rules from the SEC. Under Regulation S-X, any material item grouped under a catch-all “other” category must be broken out separately.2eCFR. 17 CFR 210.5-03 – Statements of Comprehensive Income Private businesses don’t file with the SEC, but the underlying principle still holds as best practice. If your sundry account starts looking bloated, that’s the signal to dig in and reclassify.
How Sundry Expenses Appear on Your Tax Return
If you operate as a sole proprietor or single-member LLC, your business expenses go on Schedule C. The IRS provides specific categories on Lines 8 through 27a for common costs like advertising, insurance, rent, and utilities. Anything that doesn’t fit those categories goes on Line 27b, which pulls from Part V of the form.
Here’s the part most people miss. You cannot lump everything into a single “sundry” entry on Part V. The IRS instructions require you to “list the type and amount of each expense separately.”3Internal Revenue Service. Instructions for Schedule C (Form 1040) Your internal books may group small costs under one sundry heading, but your tax return needs each expense type broken out. “Bank fees — $85” and “Office key copies — $22” are fine. “Sundry — $107” is not.
The same instructions flag items that never belong on this line at all: business equipment or furniture (which follows depreciation or separate expensing rules), permanent improvements to property, personal expenses, charitable contributions, and fines or penalties paid to any government.3Internal Revenue Service.

Costs That Don’t Belong in Sundry
Some business costs carry special deduction rules. Tossing them into a sundry account can cause you to miss a legitimate write-off or claim one you’re not entitled to. Give these their own accounts so you can apply the right tax treatment at year-end.
Meals and Entertainment
Business entertainment expenses are fully nondeductible under IRC Section 274. Client dinners and business meals generally remain 50% deductible, subject to the same statute’s limits.4Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses If you bury a $45 client lunch in sundry, you might accidentally deduct the full amount instead of half, or lose track of it entirely. Either outcome creates problems in an audit.
Equipment and Tangible Property
The IRS offers a de minimis safe harbor that lets you immediately expense tangible property costing up to $2,500 per item, or $5,000 if your business has audited financial statements. Items above those thresholds generally have to be capitalized and depreciated over time. Tracking these purchases in a dedicated account makes it far easier to apply the safe harbor correctly rather than capitalizing something that qualifies for immediate expensing, or the reverse.
Receipts and Recordkeeping for Small Costs
Small expenses get the same scrutiny as large ones if the IRS asks to see your records. For every business deduction, you need documentation showing the payee, the amount, proof of payment, the date, and a description confirming the expense was business-related.5Internal Revenue Service. What Kind of Records Should I Keep A credit card statement, a bank record, or an invoice can serve as proof. If one document doesn’t capture everything, the IRS accepts a combination of records.
There is one practical break for minor purchases. Under Treasury regulations, you generally don’t need a physical receipt for expenses under $75, except for lodging, which always requires a receipt regardless of cost.6Internal Revenue Service. Revenue Ruling 03-106 For a $12 parking fee or a $30 office supply run, a bank or credit card statement paired with a brief written note is sufficient. Grabbing the receipt anyway takes five seconds and saves real headaches later.
Keep business records for at least three years from the date you file the return. If you underreport income by more than 25%, the IRS has six years to audit. If you never file or file fraudulently, there is no time limit at all.7Internal Revenue Service. How Long Should I Keep Records
When to Stop Using the Sundry Category
A sundry account should stay small and boring. When it stops being both, something needs to change. The clearest signals that an expense has outgrown the label:
- It recurs monthly or quarterly. A cost that shows up on a regular schedule is predictable by definition. Phone service, software subscriptions, and cleaning contracts each need their own account, even if the individual amounts are modest.
- The sundry total is growing fast. If your sundry balance has doubled or tripled over a few periods, specific costs inside it are becoming material. Review the underlying transactions and spin off anything that has become significant.
- You can’t explain what’s in it. A sundry account you haven’t reviewed in months is a liability. If you can’t quickly describe what’s driving the balance, auditors and tax preparers will have the same problem.
Reclassification is straightforward. If your business starts paying a monthly graphic design subscription, move it out of sundry into something like “Software and Subscriptions.” The goal is for anyone reading your financial statements to understand where the money went without having to open the ledger and dig through individual entries. Overloaded miscellaneous accounts also undermine budgeting. You can’t forecast a cost you can’t see, and lumping recurring charges into sundry makes them invisible to anyone reviewing high-level financials. When the way your business spends money shifts, the categories should follow.
