The Complete Corporate Tax Software for Serious Preparers
Handle every business entity, every form, every filing — all from a powerful, IRS-approved desktop platform backed by APEX’s expert bilingual support.
Everything in One Package
Built for Tax Professionals Who Mean Business
TaxSlayer Pro Desktop Premium goes beyond individual returns — it’s a full-service corporate tax platform designed to grow with your practice.
Full Corporate Business Suite
Prepare and e-file federal and state returns for all major business entities — corporations, S-corps, partnerships, trusts, nonprofits, and more — from a single platform.
Unlimited Federal & State E-Filing
No per-return fees, no annual caps. File as many returns as your business can handle with IRS-authorized e-file transmission built right in.
PaperCut Document Management
Go paperless with the included PaperCut system — scan, store, and organize client documents digitally alongside each return for a fully organized office.
Digital Signature Pad Support
Capture client and preparer signatures electronically. One signature auto-populates the federal e-file authorization, state forms, and bank product documents simultaneously.
Twilio SMS Client Messaging
Communicate with clients by text message directly from inside the software via Twilio — no switching apps, no missed messages during busy season.
TaxesToGo® Mobile App
Let clients securely submit their tax documents from their phone — reducing office wait times and enabling remote intake for any return type.
Bank Product Integration
Offer Refund Advance Loans up to $7,000, Refund Transfers, check disbursements, and prepaid debit cards through built-in banking partners — no extra setup required.
Production-Ready Marketing Materials
Access professionally designed banners, door hangers, mailers, posters, and email templates — ready to brand and print for your office from day one.
W-2 Barcode Scanner Support
Speed up data entry by scanning W-2s with a 2D barcode scanner (Motorola DS6707). Client data populates automatically — no typing, no errors.
