What Are Sundry Expenses? Definition & Example
Not every business cost fits into a neat category — and that’s exactly what House Of Accounts explains here: what sundry expenses are, common examples, and how to record them correctly.
What Are Sundry Expenses?
Sundry expenses are small, occasional, or miscellaneous business costs that don’t warrant their own dedicated category in your accounts. Rather than creating a separate line for every tiny, irregular cost, businesses group them under a single “sundry expenses” heading for simplicity.
Common Examples of Sundry Expenses
- Small bank charges or transaction fees.
- One-off postage or courier costs.
- Minor stationery purchases.
- Small subscription fees for a tool used only occasionally.
- Parking fees or small incidental travel costs.
- Odd, one-time purchases that don’t recur regularly enough to justify their own category.
Why Businesses Use a Sundry Expenses Category
Creating a dedicated ledger category for every single small, irregular cost would clutter your accounts unnecessarily. Grouping genuinely minor, non-recurring items under “sundries” keeps your bookkeeping clean and readable, while still capturing every expense for tax purposes.
What Shouldn't Go Under Sundry Expenses
- Regular, recurring costs like rent, utilities, or software subscriptions — these deserve their own category.
- Large one-off purchases, which should be recorded and, where relevant, capitalised properly.
- Costs that recur often enough to justify tracking separately, even if individually small.
Are Sundry Expenses Tax-Deductible?
Yes, provided they’re genuine business costs incurred wholly and exclusively for the purpose of the business. HMRC treats sundry expenses the same as any other allowable business cost — the category is an accounting convenience, not a special tax treatment, so proper receipts and records still matter.
How to Record Sundry Expenses Correctly
- Keep a receipt or record for every sundry cost, however small — HMRC can still ask for evidence.
- Review the sundry category periodically; if a specific type of cost keeps appearing, it may deserve its own category.
- Avoid using “sundries” as a catch-all for costs you simply haven’t categorised properly — this can obscure genuine patterns in your spending.
Sundry Expenses on Your Profit and Loss Statement
On a typical profit and loss statement, sundry expenses appear as a single line item within your overheads or operating expenses section, usually positioned near the bottom alongside other minor cost categories. While individually immaterial, the total across a year can add up, so most accountants still review the sundry expenses total each year to check nothing significant is being buried inside it that deserves closer attention or its own category.
- Sundry expenses typically appear as one line within your overheads section on the P&L.
- An unusually large sundry total from year to year is worth investigating — it may signal miscategorised spending.
- Auditors and accountants often review this line specifically during year-end account preparation.
A practical habit worth adopting: review your sundry expenses category at least once a quarter rather than waiting until year-end. This makes it far easier to spot a pattern early — for example, noticing that “sundry” bank charges are actually a recurring monthly fee that deserves its own line — and keeps your management accounts genuinely useful for tracking how your business is actually performing throughout the year, not just at filing time.
Cloud accounting software makes this review far simpler than it used to be, since most platforms let you filter and export everything sitting under a given category in seconds. Rather than manually trawling through a year of transactions at tax time, a quick quarterly glance at the sundries total — comparing it to previous quarters — quickly flags anything that looks unusually high and worth a closer look before it becomes a bigger habit.
For businesses being audited or preparing accounts for a lender or investor, an unusually high or vaguely described sundry expenses line can also raise unnecessary questions, since it looks like a catch-all rather than carefully managed bookkeeping. Keeping this category genuinely small and well-documented supports a stronger overall impression of financial discipline when your accounts are reviewed by anyone outside the business.
