Compare tab

The Compare tab is the subtab on the Reports page that puts two tax years side by side. For each category (Items, Travel, Medical, and the rolled-up total excess cost), it shows the base-year total, the comparison-year total, the dollar delta, and the percent change.

The tab only surfaces when the household has data in more than one tax year. A brand-new account is single-year for its first calendar period and the Compare tab does not show; once a second year accumulates enough logged data, the tab appears.

The base year and the comparison year are user-selectable. Both are persisted in the URL alongside the scope and the active tab (?year=2026&compare=2025&tab=compare), so a comparison view is shareable and survives a refresh.

What the Compare tab is for. Year-over-year is the conversation a CPA or tax professional often has at the end of the second year: is this year's gluten-free premium consistent with last year, or is it materially different, and if so why. A household that moved, changed shopping habits, added a member, or hit a year with a major medical event will see the comparison move in predictable ways. A household whose number is wildly inconsistent for no clear reason is the case worth re-checking; not because the math is wrong, but because the comparable basket might have changed shape between years.
