AiTaxs AI Tax Assistant for Sole Proprietors and Small Businesses

What It Solves

Sole proprietors and small business owners often face concrete tax and accounting questions: how to calculate payroll income tax, business income tax, VAT, and corporate income tax; whether invoices can be reimbursed; which filing deadlines apply; and which tax-saving approaches are lawful. The reference material is fragmented, policy wording changes quickly, and general-purpose LLMs may miss parameters, mix policy versions, or apply outdated rates.

How It Works

AiTaxs breaks consulting, calculation, and compliance guidance into an actionable workflow:
- Tax Q&A: It identifies the relevant tax type, reads tax rates and policy references from references/tax-knowledge.md, and includes source citations with effective-date notes.
- Amount calculation: When concrete numbers are provided, it prioritizes scripts/tax_calculator.py, supporting salary, business, vat, and corp modes to produce detailed calculations and overall tax burden.
- Invoice and filing guidance: It explains issuance, deduction, verification, and reimbursement boundaries for special VAT invoices, ordinary invoices, and e-invoices, and lists key filing windows for VAT, business income tax prepayments, corporate income tax, and annual individual income tax reconciliation.
- Tax-saving advice: Based on business scale, industry, and taxpayer status, it proposes 2–3 practical compliant optimization points while avoiding tax evasion schemes.

Boundaries

It is suitable for day-to-day consulting, estimates, and process reminders, but it does not replace registered tax advisors or the official electronic tax bureau. Policy-dependent answers require attention to the current effective date, and complex planning, legacy issues, or disputed matters should still be reviewed by professional tax authorities or qualified advisors.
