Frequently Asked Questions.

Here are some of the frequently asked questions and their best answers for your clarification.

What business tax services does Fortress Accounting provide?

We handle federal and state tax preparation, strategic tax planning, R&D tax credits, multi-state filings, and international disclosures including Forms 5471, 5472, and FBAR. We work with C-corps, S-corps, partnerships, LLCs, and foreign-owned entities across the U.S.
It starts with looking at your full financial picture throughout the year, not just at tax time. We identify deductions you may be missing, structure your compensation strategically, maximize credits like the R&D Tax Credit, and plan around major business decisions so you are not caught off guard at filing time.
Year-round. Tax planning only works when it is proactive. We offer quarterly reviews, ongoing guidance, and availability throughout the year so you can make smarter decisions before they affect your return, rather than trying to fix them after.
Yes. We help businesses catch up on late filings, respond to IRS notices, and get into compliance without unnecessary penalties. We assess where you stand, file what is needed, and put a plan in place so it does not happen again.
Yes. We work with businesses operating in multiple states and manage complex state and local tax requirements, including nexus analysis, apportionment, and jurisdiction-specific compliance. If you sell or operate in multiple states, this is something you need to get right.
