What it means
Every business generates a trickle of money outside its core trade. A bakery sells used oil to a recycler, a workshop sells metal offcuts, a landlord receives a small commission from a laundry operator, and an office collects an overpayment refund from a utility.
None of these are what the business is for, and none is large enough to report separately, so they are pooled into sundry income. The reason it sits below the main revenue line matters for anyone reading the accounts.
Revenue should reflect what the business actually sells, because growth rates, gross margin and revenue multiples are all calculated from it. Mixing a one-off insurance refund into sales would flatter the trend and mislead anyone using it to forecast.
Sundry income normally appears in other operating income, after gross profit and before operating expenses, or occasionally as a deduction from a related cost. It is still taxable income in most jurisdictions, and it still needs a proper audit trail, so the informal name should not imply informal treatment.
The main control issue is that small, irregular receipts are exactly the ones that go missing. Scrap cash, rebate cheques and refunds often bypass the normal sales process, so businesses should insist they are banked, recorded against a named sundry account and reviewed monthly by someone other than the person who receives them.
The other discipline is size. If any item inside sundry income becomes material or starts recurring predictably, it should be moved out and reported on its own line, because a bucket labelled miscellaneous stops being acceptable once it is large enough to influence a reader's judgement.
In practice
Real-world examples.
Example
An engineering workshop sells its steel swarf and offcuts to a scrap merchant roughly every six weeks, receiving between $600 and $1,200 each time. The bookkeeper posts every payment to sundry income and reconciles the total to the scrap merchant's remittance advices at year end.
Example
A serviced office operator receives $3,400 across the year in commissions from the coffee vending supplier and the on-site dry cleaner. Neither relates to the licence fees it charges tenants, so both sit in sundry income rather than inflating occupancy revenue.
Example
A haulage firm receives a $2,100 refund after successfully disputing a fuel card administration charge. Because it relates to a prior period cost that has already been closed, the finance manager records it as sundry income in the current year rather than restating last year's fuel expense.
Formula
Calculation
Sundry income = Sum of individual immaterial income items outside core trading revenue
Sundry income as a share of revenue = Sundry income / Total revenue
A mid-sized joinery business closes its year with core revenue of $4,700,000 from cabinetry contracts. Its bookkeeper reviews the miscellaneous receipts and finds four items that belong in sundry income.
Timber offcuts and sawdust sold to a biomass supplier: $4,200
Volume rebate received from a hardware supplier: $1,800
Insurance refund on an overcharged vehicle policy: $2,500
Commission from the vending machine in the staff room: $900
Sundry income = $4,200 + $1,800 + $2,500 + $900 = $9,400
Sundry income as a share of revenue = $9,400 / $4,700,000 = 0.2%
At 0.2% of revenue, the total is comfortably immaterial and grouping it on one line is appropriate. If the offcut sales alone grew to $180,000 through a recurring supply agreement, that item would need its own revenue line, because at nearly 4% of turnover it would be a genuine second income stream rather than a stray receipt.Case study
Seen in the real world.
Ashfield Joinery is a fictional business used purely as an illustrative example of how sundry income can quietly stop being sundry. For years its miscellaneous line held around $9,400, made up of offcut sales, a supplier rebate, an insurance refund and vending commission, which nobody questioned against $4,700,000 of cabinetry revenue.
Then the yard manager negotiated a standing contract with a biomass plant to take all timber waste at a fixed weekly rate. Within eighteen months that single arrangement was producing $180,000 a year, but it was still being posted to sundry income, so the board's revenue reports showed a flat core business and an unexplained lump of other income.
When a prospective buyer reviewed the accounts, the confusion cost Ashfield credibility and time, because a recurring, contracted and reasonably predictable $180,000 stream is worth considerably more than a miscellaneous receipt. The illustrative lesson is to run an annual review of what sits inside sundry income and promote anything that has become material or recurring to its own reported line.
Watch out
Common mistakes.
- Letting sundry income grow into a catch-all for anything the bookkeeper cannot immediately code, which hides errors and makes the account impossible to explain.
- Treating small scrap or rebate receipts as informal cash outside the accounting system, which creates both a tax exposure and an obvious opportunity for loss.
- Adding sundry income into the revenue figure used for growth rates or valuation multiples, which overstates the performance of the actual trading business.
Questions
People also ask.
Is sundry income taxable?
In almost all cases yes, because tax authorities look at the nature of the receipt rather than the label the business puts on the account.
How large can sundry income get before it needs its own line?
There is no fixed threshold, but once an individual item would change a reader's view of the business, usually somewhere around 1% to 5% of revenue depending on context, it should be reported separately.
What is the difference between sundry income and other income?
They largely overlap in everyday use, though other income is the broader heading that may also include material items such as interest received or gains on asset disposals.
