Returns a pre-signed S3 URL. To enable the Tax Estimates feature for your customers, request access from your Layer representative. Generates a downloadable tax document for the requested `year` and returns a pre-signed S3 URL. The URL is time-limited; download the document promptly after receiving it. ## Document types The `type` query parameter selects which document to export: * `TAX_PACKET`: a combined packet containing the business's tax summary and supporting detail for the year, suitable for sharing with a tax preparer. * `SCHEDULE_C`: a Schedule C (profit or loss from business) export derived from the business's P\&L data for the year. * `PAYMENT_HISTORY`: the quarterly estimated tax payment history, mirroring [Get tax payments](/api-reference/v1/tax-estimates/get-tax-payments) in downloadable form. ## OpenAPI ````yaml post /v1/businesses/{businessId}/tax-estimates/export openapi: 3.0.1 info: title: API version: latest servers: [] security: - BearerAuth: [] tags: [] externalDocs: url: / paths: /v1/businesses/{businessId}/tax-estimates/export: post: tags: - Tax Estimates summary: Export tax documents description: Generates tax documents for download.
