Automate tax workpaper preparation for 1040, 1120, 1120-S & 1065
Tax workpapers are the supporting schedules that evidence every figure on a filed return — deduction support, M-1 adjustments, K-1 allocations, basis schedules, NOL carryforwards, and depreciation. Building them manually from client financials takes hours every filing season. Rima automates the entire process. Send your financial records and source documents via Slack or email and get back completed, reviewer-ready tax workpapers in your Excel templates — within 3 hours.

Tax workpapers are the supporting schedules prepared during tax return preparation that evidence every figure on a filed return — income schedules, deduction support, depreciation calculations, carryforward schedules, and entity-specific documents like Schedule K-1 allocations. For US CPA firms, they are required for professional standards compliance and provide the audit trail between the client's financial records and the filed Form 1040, 1120, 1120-S, or 1065.
