For Businesses & Corporations
SIM TAX brings Big Four and national-firm depth to your organization — as a dedicated external tax advisor that integrates with your team, plans proactively, and delivers results year-round.
The Credential
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
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
From structuring decisions to year-round advisory, we handle the full tax lifecycle of your business with institutional rigor.
We design the optimal structure — LLC, S-Corp, C-Corp, or partnership — and build a tax plan that scales with your business. Every decision is made with long-term efficiency in mind, not just this year's filing.
2026: the qualified business income deduction is now permanent, so S-Corp reasonable-compensation planning has to solve for payroll tax and the QBI wage limitation together. Section 174A also restores immediate expensing of domestic R&D.
Federal and state filings for corporations and partnerships prepared with Big Four rigor. Complex returns, multiple schedules, K-1s — handled completely and on time.
2026: the 1099-NEC/MISC reporting threshold rises to $2,000 for payments made this year, and 1099-K reverts to $20,000 and 200 transactions. The IRS is also retiring the FIRE system ahead of the 2027 filing season — electronic filers move to IRIS.
Cross-entity allocations, K-1 management, and coordinated filing across complex ownership structures. We manage the full picture so nothing falls through the cracks.
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.
Nexus analysis, apportionment, and state filing obligations wherever your business operates. We stay ahead of compliance so your growth never creates unexpected exposure.
Check your own exposure with our free State Compliance Tool. In Texas, the 2026 franchise tax threshold is $2.65 million — entities below it owe no tax but still file a Public Information Report.
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.
2026: new deductions for qualified overtime ($12,500 single / $25,000 joint) and tips (up to $25,000) change payroll setup and reporting — particularly for healthcare and professional-services employers.
Industries
Every industry carries its own tax complexity. We bring sector-specific knowledge so nothing specific to your business gets missed.
Real estate operators face some of the most complex tax situations in business — multiple entities, passive income rules, depreciation timing, and capital events. We bring deep real estate tax experience to every engagement.
100% bonus depreciation is now permanent for qualified property acquired after January 19, 2025, and the Section 179 limit sits near $2.5 million (indexed) — the ROI on a cost segregation study has changed materially.
Houston's energy sector demands advisors who understand the full tax toolkit — from depletion deductions to JV structuring. We serve upstream, midstream, and energy services companies with the depth the industry requires.
The OBBBA begin-construction deadline of July 5, 2026 for solar and wind credits has now passed. Projects that missed it should be evaluated against the December 31, 2027 placed-in-service backstop.
Physicians and healthcare operators have unique compensation, retirement, and entity considerations. We help medical practices and group practices structure themselves efficiently and plan proactively throughout the year.
Law firms, consulting firms, and service businesses navigate SSTB rules, partner equity, and multi-state complexity every year. We bring structure and strategy to firms that have outgrown their current tax approach.
How We Work
Every engagement follows the same disciplined process — because consistency is the foundation of good tax advisory.
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.
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.
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.
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.
Your first consultation is free. We'll review your current structure, identify your exposure, and outline a plan — no obligation.
