Home Carer Tax Credit and joint assessment (2026)

The Home Carer Tax Credit can apply in households where one spouse stays at home to care for a dependent. In practice, it can make the household outcome more sensitive to the second income if that income is near the eligibility thresholds.

If the second income is close to a threshold, small changes can flip the best option. That is why scenario testing (for example, testing €6k vs €8k vs €10k of second income) is often more useful than a single point estimate.
