Apex Tax
Real-Time Tax Visibility, No Surprises at Filing Time
Apex Tax automates the complete tax reporting lifecycle — from calculating tax liability to generating IRS-ready forms — with real-time transparency that helps keep you audit-ready all year long. Our unified platform supports a comprehensive array of tax forms across traditional securities, retirement accounts, and digital assets.
Available as a unified platform with Apex Cost Basis or as a standalone module, Apex Tax includes optional Business Process Outsourcing (BPO) services to handle daily reconciliation, corporate actions, wash sales, and income reclassification — so you can focus on growing your business instead of issuing forms.
- Broad Form Coverage: Support for 17 U.S. IRS and Puerto Rico forms
- Real-Time Tax Statements Year-Round: Generate draft tax statements on demand anytime, not just during tax season
- Electronic Filing Ready: Direct integration with IRS filing systems (FIRE and IRIS) for federal and state tax reporting
- Note that FIRE is retiring on December 31, 2026. The IRS is replacing the FIRE system with the Information Returns Intake System (IRIS), and Apex will be running both through year-end. We suggest that you apply for your IRIS Transmitter Control Code (TCC) as early as possible, since it can take up to 45 days to receive it.
- Automated Income Reclassification: Daily automated processing handles complex income reclassification for mutual funds and REITs with seamless return-of-capital processing between Tax and Cost Basis systems
Supported Tax Forms
Automatically Generate These Tax Forms
Apex supports a full spectrum of U.S. IRS and Puerto Rico tax forms across traditional securities, retirement accounts, and digital assets. We strive to integrate IRS-mandated forms ahead of their required reporting season — like we did with the 1099-DA and 1099-K in 2025 — giving your team time to test, validate, and prepare.
