Design one single mobile app icon for the App Type, using the Icon Concept as a bold, instantly readable central symbol. Render the Icon Style with crisp edges, a strong silhouette, comfortable padding and smart negative space, keeping the receipt and checkmark as one unified form rather than a detailed illustration. Use the Color Palette with strong contrast between the symbol and the rounded-square background. Present the icon as an iOS-style squircle with smooth rounded corners, centered on a plain very light neutral background. The icon should fill about 70 percent of a square 1:1 canvas and cast a soft, subtle shadow beneath it. Show no device, hands, mockup, extra objects, text, letters, watermark, glow or decorative effects. Make it feel original and refined, like a top Dribbble or Behance app icon shot, while remaining clear at small sizes.
Use these details:
App Type: "Tax filing app"
Icon Concept: "A paper receipt curling into a checkmark"
Icon Style: "Simple duotone icon"
Color Palette: "Emerald green and white"
