Freelancer Expense & Tax Calculator

Auto-track expenses and calculate quarterly taxes for freelancers. Connect bank, get tax estimates.

Tax season is freelancer anxiety season. You know that sinking feeling: opening a spreadsheet in March, trying to reconstruct what you spent over the past year, praying you kept enough receipts. Then paying an accountant $400 to tell you that you owe more than expected.

QuickBooks Self-Employed exists but costs $15/month and does way too much. Most freelancers don't need double-entry bookkeeping — they need to know three things: how much they made, how much they can deduct, and what they owe.

A dead-simple tax calculator that connects to your bank account and automatically categorizes expenses into deductible vs. non-deductible would save freelancers both money and panic attacks. No invoicing. No payroll. Just taxes. The one thing every freelancer dreads and nobody makes easy.

Why Now?

The gig economy and remote work created millions of new freelancers since 2020, many filing taxes independently for the first time. IRS enforcement budget increased significantly, meaning more audits. Plaid makes bank connections easy. AI can auto-categorize expenses with 95%+ accuracy. The pain is universal and recurring (literally — every quarter).

📊 Market Evidence

The Market Gap

QuickBooks Self-Employed is bloated and confusing for simple freelancers. Wave is free but lacks tax-specific features. Keeper Tax is close but clunky. Nobody owns 'dead simple freelancer taxes' at $12-25/month with modern UX and smart auto-categorization. The opportunity is in doing LESS, not more.
