Direct answer
SARS can potentially ring-fence an assessed loss from certain trades, which can limit its set-off against income from other sources. This is not decided simply because an activity is part-time, unpopular or loss-making. The rule is technical and depends on the applicable statutory tests, the taxpayer’s income position, the nature and history of the trade, and the facts showing whether there is a reasonable prospect of taxable income within a reasonable period.
The SARS ITR12 guide describes section 20A ring-fencing and refers to a facts-and-circumstances test. Do not use a social-media rule of thumb or a prior-year outcome as a substitute for current analysis.
What this means in practice
Keep separate records for each trade. A freelance service, creative activity, rental activity, consulting practice, farming activity or other side business should have its own income, expense, asset and liability evidence. Mixing the activity’s transactions with salary, family spending or a different business makes it hard to establish whether there is a genuine trade and what loss actually arose.
The history matters. Preserve prior-year returns, accounts, budgets, invoices, client contracts, marketing records, business plans, funding evidence, product-development records and explanations for unusual loss years. A new business may have different evidence from an established business in a temporary downturn. The relevant question is not whether the owner hopes it will succeed, but what objective facts show about the activity and its prospect of taxable income.
Do not use the phrase “side business” as a tax classification. A trade can be carried on alongside employment, and a loss may still need detailed consideration. Equally, a genuine activity can fall within technical ring-fencing rules. The relevant tests and affected trades should be assessed against current law and SARS guidance, not merely the amount of time spent after hours.
If a loss is potentially ring-fenced, record the issue before submitting the ITR12. Do not offset it against salary, investment income or another trade merely because accounting software produced a negative number. Keep the calculation and an explanation of how the loss was determined. Errors can arise from personal costs, unsupported expenditure, asset allowances, unrecorded income or incorrect allocation between activities.
Step-by-step
- Prepare separate trade accounts.
List income, expenses, assets, liabilities and transactions for the activity independently from salary, investment and household records.
- Reconcile the loss.
Trace income to invoices and bank records, and expenses to invoices, payment proof and trade purpose. Remove personal or unsupported items before analysis.
- Build a history file.
Keep prior returns, accounts, budgets, contracts, marketing, business plans and records explaining loss years or delays.
- Identify the relevant facts.
Record the nature of the trade, time devoted, commercial activity, income history, costs and objective evidence of a prospect of taxable income.
- Check current technical guidance.
Use the current SARS ITR12 guide and obtain advice on the statutory tests before deciding whether set-off is available or restricted.
- Preserve the working papers.
Retain calculations, evidence, return and assessment. SARS says ITR12 supporting records should be kept for at least five years.
Documents and records to keep
- Separate income and expense ledger for the activity.
- Invoices, contracts, client communications and bank records.
- Prior-year accounts, ITR12 returns and assessments.
- Business plan, budgets, marketing, quotes and proof of commercial activity.
- Asset register, allowance workpapers and records supporting any loss figure.
Important limits and exceptions
This is not a section 20A opinion and does not state a threshold, an affected-trade list or a conclusion for any taxpayer. Those matters should be verified from current law and official guidance. The activity may also raise issues separate from ring-fencing, including whether it is a trade, whether expenditure is deductible, how assets are treated and whether income was fully recorded.
Do not label a genuine commercial loss a “hobby loss” or assume that a hobby has become a trade without evidence. Do not rely on a previous assessment as a permanent approval. A material loss, a history of repeated losses, high-income circumstances or unusual expenses merits tailored review before the return is filed.
When to get tailored advice
Get professional advice before offsetting a significant side-business loss against other income, especially where losses recur, the trade has assets, records are mixed, or the taxpayer has several income streams. TaxProof can prepare the separate activity file and loss reconciliation for technical review.
