Accounting & Tax Services
Financial reporting, tax preparation, and audit management built by accounting professionals.
Accounting & Tax Services is in expert discovery. M44 is documenting requirements with working CPAs and tax professionals, and recruiting founding contributors who define what the application must solve.
Industry landscape
The accounting industry provides financial reporting, tax preparation, audit services, and advisory support to businesses and individuals navigating complex regulatory and tax environments. Accounting firms range from Big Four global practices and national regional firms to local CPA practices serving small businesses and individual clients. State boards of accountancy regulate CPA licensing, enforce ethics rules, and oversee continuing professional education requirements. The AICPA (American Institute of CPAs) provides professional standards, while FASB and GASB set GAAP accounting standards that govern financial reporting.
Tax seasons concentrate work around federal and state filing deadlines, with practitioners preparing individual returns, corporate tax filings, partnership K-1s, and navigating multi-state tax obligations. Audit engagements require examining financial statements, testing internal controls, and issuing opinions on compliance with GAAP. Advisory services span business consulting, transaction support, and specialized areas like SOX compliance, R&D tax credits, and SALT (state and local tax) planning. The fragmentation between tax preparation software, audit management systems, and client communication platforms creates operational complexity.
Accounting & Tax Services is in expert discovery: M44 is documenting requirements with domain experts in tax preparation, audit procedures, and client service workflows. The application's foundation is real expertise from CPAs and tax professionals — not generic AI trained on scraped internet data.
Market context
The U.S. accounting industry employs over 1.4 million professionals across 45,000+ CPA firms and corporate accounting departments. The Big Four firms (Deloitte, PwC, EY, KPMG) employ over 250,000 professionals in the United States, while regional and local firms serve middle-market companies and individual clients. State boards of accountancy regulate over 650,000 active CPA licenses. The IRS processes over 150 million individual tax returns and millions of business returns annually, with state tax agencies adding additional filing requirements across 50 jurisdictions.
What M44 is building here
The Accounting & Tax Services application targets tax preparation efficiency, audit management, and client service. The approach: expert-built software designed by CPAs who understand real tax workflows — not generic AI that doesn't distinguish between Schedule C sole proprietorship rules and partnership K-1 allocations. Domain experts who prepare multi-state tax returns, conduct financial statement audits, and advise clients on complex tax positions are documenting the requirements.
Measures of success
Design scope for the Accounting & Tax Services application: automated tax return preparation and review, audit documentation management, client data organization, multi-state tax compliance tracking, professional judgment documentation, and client communication workflows. Discovery is focused on how firms manage tax season workflows, what audit documentation looks like across engagement types, and how client service holds up during capacity-constrained periods.
