Each summary field includes a corresponding URL for retrieving itemized breakdowns. To enable the Tax Estimates feature for your customers, request access from your Layer representative. Returns the highest-level tax roll-up for top-of-dashboard display. This is the lightest of the Tax Estimates endpoints; use it for headline numbers, and use [Get tax details](/api-reference/v1/tax-estimates/get-tax-details) for the itemized calculation behind them. ## What the numbers mean Each field is derived from the same calculation as [Get tax details](/api-reference/v1/tax-estimates/get-tax-details), rolled up: * `total_income`: total business income (Schedule C revenue) plus any W-2/other income included in the calculation, in cents. * `total_deductions`: total deductions applied (business expenses, vehicle, home office, qualified tip/overtime, self-employment tax deduction), in cents. * `taxable_income_estimate`: the estimated taxable income after deductions, in cents. * `estimated_taxes_owed`: total projected tax liability (federal + state), in cents. * `taxes_due_date`: the next tax deadline in ISO-8601 date format. ## OpenAPI ````yaml get /v1/businesses/{businessId}/tax-estimates/overview openapi: 3.0.1 info: title: API version: latest servers: [] security: - BearerAuth: [] tags: [] externalDocs: url: / paths: /v1/businesses/{businessId}/tax-estimates/overview: get: tags: - Tax Estimates summary: Get tax overview description: >- Returns high-level tax summary for dashboard display.
