The detailed income statement and who reads it
What the detailed income statement adds to a set of annual financial statements, why it sits outside the reported set, who uses it and how it is built.
By Achekam · · 4 min read · For Accountants & audit firms in South Africa, Nigeria, Kenya
Turn to the back of most South African sets of annual financial statements for small companies and you will find a page or two headed "Detailed income statement". It lists every income and expense account, often dozens of lines, from bank charges to cleaning. Nigerian and Kenyan practices produce similar schedules under other names. Owners read it more closely than anything else in the set.
Yet it is not one of the primary statements, and it should not be read as though it were. This article explains what the detailed income statement shows, why it sits outside the statements a practitioner's report covers, who relies on it and how Achekam produces it.
What it shows that the primary statement does not
The statement of comprehensive income, or the income statement where it is presented separately, is designed for outside readers. It aggregates: revenue, cost of sales, a handful of expense categories, finance costs, tax. The presentation standards ask for enough lines to understand performance, not for a copy of the ledger.
The detailed income statement does the opposite. It breaks those totals down to something close to account level:
- revenue by stream, where the ledger records it that way;
- cost of sales, often showing opening stock, purchases and closing stock;
- each operating expense separately: rent, salaries, motor vehicle expenses, telephone, insurance, repairs, professional fees;
- other income and finance costs in detail.
An owner can see at a glance why profit moved. A primary statement that says "Operating expenses" went up tells them far less.
Why it falls outside the statements the report covers
Because it is a schedule of detail, the detailed income statement is generally presented as supplementary information rather than as part of the financial statements prepared under the framework. That has consequences:
- The practitioner's report does not extend to it unless the engagement says so. An audit or review conclusion is on the financial statements; a compilation report describes what was compiled. The detailed schedule usually falls outside that scope, and should say so.
- It must still agree. Being outside the report is not a licence to differ. Every subtotal in the detail must agree to the corresponding line in the primary statements.
- It must not contradict. A reader who sees "Directors' remuneration" in the detail and nothing about it in the related-party note will ask why.
Who uses it: owners, lenders and the tax computation
Three groups of readers rely on it.
Owners and managers use it to understand the cost lines the primary statements combine. For many small companies it is the only management information anyone reads all year.
Lenders often ask for it with the annual statements, to see what the costs are made of and how much of the cost base the owner could cut.
The tax computation starts from it. Adjustments for non-deductible items, such as fines or donations without the right receipts, are much easier to make from a detailed list than from aggregated lines. In South Africa the company's figures feed the ITR14 return, and SARS's guide to completing the ITR14 for companies gives step-by-step help with completing it accurately. Achekam does not submit tax returns to SARS; the firm files them itself and records the filing in Achekam.
Built from the same mapped trial balance as everything else
In Achekam, the detailed income statement is part of the draft set the Studio builds from a mapped trial balance, alongside the directors' report, the four primary statements, the policies and the notes. Every figure in it is calculated in code from the same mapping, which is the main protection against the detail and the summary disagreeing.
Some practical consequences:
- Mapping decides the detail. If an account is mapped to the wrong line, it shows in the wrong place in both the summary and the detail. Fix the mapping, not the schedule.
- Row titles can be reworded. A firm can change the wording of any row title and add its own lines and groups, and later builds keep those choices. Owners recognise their own account names, so consider using them.
- It comes out with the rest of the set. Staff download the statements as an A4 PDF made on Achekam's server, and issuing stores the final PDF with a fingerprint and locks that version. The board and tax packs are the statutory set under another name, and their cards list what is not yet included, which is worth reading before a pack goes to a lender or into the tax computation.
The notes that sit beside it take their figures from the same mapped trial balance, and anything the ledger cannot supply is left as "[to be completed]". Sign-off follows the usual rules too: each set names a preparer, a reviewer and an engagement partner, and only a user with a partner role can sign.
Labelling it so readers know it is supplementary
Readers cannot be expected to know where the financial statements end. Make it obvious:
- Place the detailed income statement after the notes, not among the primary statements.
- Head it clearly and state that it does not form part of the financial statements and is presented as supplementary information.
- Make sure the practitioner's report describes the pages it covers in a way that leaves the detail out, where that is the case.
- Use the same headings in the detail as in the primary statements, so totals can be traced from one to the other.
When an owner asks why a favourite expense line has "disappeared" from the income statement, the detailed schedule is usually the answer. How the expense lines in the primary statement are grouped in the first place is covered in presenting expenses by nature or by function, and the packs built from the same set in board packs and tax packs.
