The Credential
Big Four depth,
at every engagement.
SIM TAX was founded by Barbara Chrzanowska, EA, PMP — a tax strategist whose career spans PwC, EY, BDO, and RSM. She has led engagements for private equity portfolio companies, family offices, and multi-entity corporate structures across the Southwest.
That institutional experience — the processes, the precision, the awareness of where complexity hides — now serves every SIM TAX client directly.

The Difference
A partner, not
a vendor.
At a large firm, you get a rotating cast of associates and a billing clock that runs on every call. At SIM TAX, you work directly with your advisor — someone who knows your business, plans ahead, and is available when decisions need to be made.
We integrate with your existing team — CFO, controller, bookkeeper — and think like a partner in your business, not a service provider who appears at filing time.

What We Do
Comprehensive tax services for your organization.
From structuring decisions to year-round advisory, we handle the full tax lifecycle of your business with institutional rigor.
Business Tax Preparation
Federal and state filings for corporations and partnerships prepared with Big Four precision. Complex returns, multiple schedules, K-1s — handled completely and on time.
Multi-Entity & Partnership Tax
Cross-entity allocations, K-1 management, and coordinated filing across complex ownership structures. We manage the full picture so nothing falls through the cracks.
External Tax Advisory
We work alongside your CFO, controller, or bookkeeper as a dedicated strategic tax partner — available year-round for planning, questions, and decisions, not just at filing time.
Multi-State & Nexus Compliance
Nexus analysis, apportionment, and state filing obligations wherever your business operates. We stay ahead of compliance so your growth never creates unexpected exposure.
Executive & Owner Compensation
Optimize salary, distributions, and benefits structures for owners and key executives. We align personal and business tax strategies so both sides of the ledger work together efficiently.
Industries
Deep expertise in your industry.
Every industry carries its own tax complexity. We bring sector-specific knowledge so nothing specific to your business gets missed.

How We Work
From first call to year-round partner.
Every engagement follows the same disciplined process — because consistency is the foundation of good tax advisory.
01
Discovery & Assessment
We start with a complimentary strategy session to review your entity structure, current tax exposure, and goals. No templates — every engagement begins with understanding your specific situation.
02
Strategic Tax Plan
We build a documented year-round tax plan aligned with your business objectives. You receive clear recommendations, projected impact, and a calendar of actions — not just a return.
03
Execution & Filing
We prepare and file all required federal and state returns with institutional accuracy. Every number is checked. Every position is documented. Every deadline is met.
04
Year-Round Advisory
Quarterly planning reviews, proactive outreach before major decisions, and on-call guidance throughout the year. You always know where you stand — and what comes next.
