Start with the person who earns the income
Pillar 3a eligibility is personal. Helping with administration, deliveries or customer calls in a spouse’s business can be economically important without creating a qualifying income for the helper. Circular 18a addresses collaboration between spouses: to claim a 3a deduction for the collaborating spouse, the couple must demonstrate employment beyond ordinary mutual assistance, with OASI contributions deducted from that spouse’s earnings and recorded in their name. A shared household budget, a joint account or the business owner’s own contributions do not establish that evidence.
Compare two genuinely different situations
Imagine a florist whose spouse occasionally helps with stock and receives no wage and no earnings credited for OASI. That help alone does not establish 3a eligibility. In a second fictional case, the spouse works under a documented employment arrangement with agreed duties and pay, and the compensation office records contributions in their name. Those documents give the couple a basis to verify eligibility and the applicable contribution limit; they do not automatically prove a particular deduction. If the spouse already has a qualifying job elsewhere, check that income and occupational-pension affiliation as well.
Make the file agree across payroll and tax
Ask your payroll adviser and compensation office which status they recognise, from what date, and which evidence supports it. Keep the employment agreement, payslips and payments, and verify that the 3a account or policy is in the contributor’s name. Ask the tax authority how it wants the individual income and pension contribution shown. Do not backdate an arrangement or assume paying a 3a provider creates qualifying earnings. If duties or compensation change, update the record before calculating the annual limit rather than using the business owner’s limit for both spouses.
Avoid counting the same income twice
When household money flows through one account, trace the payer and the person to whom the income belongs instead of tracing only the bank debit. Keep each spouse’s contribution certificate beside their own employment or income evidence. This matters even if both policies are with the same insurer. If you cannot tell whose income a statement records, get a corrected explanation before estimating either spouse’s deduction.
Keep protection planning separate from the deduction
If there is no qualifying income, the family can still discuss freely available savings or a suitable 3b arrangement, without treating it as a substitute 3a deduction. Review what would happen to household income if either person stopped working, and whether existing pension, death and disability protection covers the actual household needs. If you are considering paying a salary, look at the overall employment and social-insurance implications with your advisers, not just the potential 3a deduction. The useful next step is a verified income and protection picture for each spouse.
