6 areas

worth a closer look

Typical for similar filers

$14,256–$33,671/yr

Benchmark for areas we can't see on your return (e.g. giving, 401(k) features).

Most of these levers are still open — plan them in Deductsy before Dec 31.

Estimates only — not tax advice. Confirm with a CPA.

Example — typical ranges for a profile like this. Illustrative ranges for similar filers, not your results. Upload your Form 1040 to see precise figures for the categories we can read from your return.These are 2026 numbers — savings you can still act on. Unlike last year's return (already filed — nothing left to change), most of these moves — topping up your 401(k) or HSA, a Roth / backdoor Roth, a dependent-care election, harvesting a stock loss, a cost-segregation study — only count for 2026 if you make them by December 31, 2026. That's why it's worth a look now, not next April.
