Solo freelancers and consultants with variable monthly income overpay or underpay quarterly estimated taxes and have no tool that handles irregular income correctly
HN thread on consultant tax software (298 upvotes + 187 comments) shows strong community pain: CPAs charge $1800-6000/year for services that don't include proactive optimization, TurboTax misses deductions (QBI, solo 401k, home office), and quarterly estimated tax calculation assumes stable income which solo consultants don't have. Multiple commenters describe custom spreadsheets using the 'annualized income installment method' because no software implements it correctly for variable income. KeeperTax uses AI to find deductions but doesn't solve the quarterly estimation problem for irregular earners. Stated prices paid: $1800-6000/year to CPAs. WTP for software: $150-500/year clearly implied by the delta vs CPA cost.

Gap Assessment
QuickBooks Self-Employed, FlyFin, KeeperTax all exist but commenters on HN 33843816 still use custom spreadsheets for annualized income installment method. None handles the edge case of a high-income month in Q3 and low-income Q1/Q2 without over-penalty. The gap is specifically the annualized method + deduction discovery + S-Corp election modeling in one sub-$300/year product.
