The Opportunity

Problem

Solo indie hacker founders cannot find reliable, affordable accountants who specialize in understanding indie hacker businesses.

Solution

SoloTaxify scans your transactions, applies indie-specific deductions (tools, ads, home office), and preps e-filed returns for US solopreneurs. It handles multi-state sales tax for digital products and generates audit-proof logs. Affordable alternative to accountants with one-click quarterly filings.

Target Audience

Solo indie hacker founders running bootstrapped online businesses

Differentiator

Built-in rules for 20+ indie deductions overlooked by TurboTax, like SaaS affiliate commissions.
