Free Tax, Accounting & Bookkeeping Guides for NJ Business Owners
Free guides, tools, and expert articles to help NJ business owners make smarter tax and financial decisions.
Tax and accounting decisions get made every week in a small business — most of them quietly, by an owner doing their best between a sales call and a payroll run. The resources below exist for those moments. They are not a substitute for a CPA who knows your situation, but they will help you ask better questions, recognize when something deserves professional attention, and avoid the most common (and most expensive) self-inflicted tax mistakes.
Everything here is written by our CPA — licensed in New Jersey and New York — and tailored to small-to-mid-size businesses, executives, and high-income individuals operating across the NY/NJ/PA tri-state corridor. Federal rules apply uniformly; state and local rules diverge constantly. Where it matters, our content calls out NJ-specific, NY-specific, or PA-specific treatment so you don't act on generic guidance that doesn't reflect your jurisdiction.

How to Use These Resources
If you are just starting a business, begin with our entity-selection guide and the QuickBooks setup walkthrough — both are linked under Guides & Checklists. The decisions you make in the first ninety days (LLC vs. S-Corp election, accounting method, chart of accounts) compound for years. Getting them right at the start is dramatically cheaper than reworking them later.
If you are preparing for tax season, the Tax Calendar lists every federal and NJ deadline that affects pass-through entities, C-corps, payroll, and individual filers. Pair it with the document checklist on the Guides page so nothing in your records gets overlooked. Most taxpayer underpayment penalties trace back to a missed quarterly estimate, not a botched return — the calendar exists to prevent that.
If you are actively managing a business, the blog is the most actively updated section. We publish on NJ-specific topics (the SALT workaround, BAIT election mechanics, sales-tax nexus changes), federal updates that move the needle for small businesses (Section 179, bonus depreciation, R&D capitalization), and recurring problems we see in client engagements (mismatched 1099s, incorrect S-Corp shareholder basis, missed reasonable-compensation analysis).
If your situation is outside the patterns these resources cover, that is the right time to talk to a CPA. The IRS does not give partial credit for good-faith reliance on a generic article. Schedule a free consultation and we will work through your specific facts.
These resources explain common tax and accounting questions, with links to source material and notes on scope where relevant. Tax rules change, and the right approach depends on your facts. Use the material as background for a discussion with your CPA.
If you would rather scan everything at once than work down from a category, the full site directory lists every published page in one place — services, industries, service areas, calculators, and the complete blog archive.
If you are an existing ProAxis client, the resources here are intended to supplement — not replace — the conversations you are already having with your engagement CPA. Specific tax positions on your return depend on facts only your CPA has full visibility into, and a published article cannot capture the weighing of facts that goes into a real recommendation. Use the resources as background context that makes the engagement conversation more productive, and route the actual decisions through the engagement.
