Single assessment for married couples: why it appears in comparisons

Single assessment can be a useful baseline because it treats each spouse independently. Comparing against it helps you see whether joint or separate assessment is adding value in your scenario.

In some two-income scenarios where both spouses use most of their own bands and credits, the difference between options can be small. That is a cue to test sensitivity rather than assume one option is always best.

Compare the ranking first, then adjust one input at a time. If the best option changes frequently with small input changes, treat the choice as sensitive and review related factors like credits and pension.
