Starting a business is exciting—but it can also be overwhelming. At Fortitude Tax & Accounting, we help new business owners build a strong financial foundation from day one. Our team guides you through choosing the right business entity (LLC, S Corp, or sole proprietorship), setting up your books correctly, and creating a proactive tax plan tailored to your goals. With the right structure and systems in place, you’ll avoid costly mistakes, stay compliant, and accelerate your growth.
Whether you’re launching your first side hustle, opening a professional practice, or growing a service business, Fortitude provides startup accounting, tax guidance, and bookkeeping support designed to keep more money in your pocket as you scale.
Your company’s financials are more than numbers—they’re the scorecard for your business. When your books are organized, accurate, and up to date, you can see exactly where your business stands and where it’s headed.
Clear financials build trust with banks, investors, and key stakeholders, giving them confidence in your business’s health and future. More importantly, they give you the confidence to make smart investments, manage cash flow, and plan your next stage of growth without second-guessing.
At Fortitude Tax & Accounting, we help startups and new business owners create the kind of financial clarity that drives funding, opportunity, and long-term success.
Based in Stansbury Park, Utah, Fortitude Tax & Accounting helps new business owners, entrepreneurs, and service professionals nationwide with bookkeeping, proactive tax planning, and business entity setup.
Whatever stage your business is at, Fortitude operates as your back-office accounting team—at a fraction of the cost of hiring in-house staff. And when you’re ready to grow and build your own team, we’ll help make that transition smooth.
Our startup accounting services include:
The right entity depends on your income, liability needs, and long-term goals. Many small business owners start with an LLC for liability protection, while others benefit from electing S Corporation status to save on self-employment taxes. At Fortitude Tax & Accounting, we evaluate your unique situation and recommend the structure that provides the best tax advantage.
An LLC is simple to set up and provides liability protection, making it a popular choice for new business owners. An S Corp may reduce self-employment taxes if your business is profitable enough to pay yourself a reasonable salary. We’ll guide you through the pros and cons of each so you don’t leave money on the table.
Yes! We not only help you choose the right entity, but also file the necessary documents with your state, handle your S Corp election if applicable, and make sure everything is compliant from the start. Our process saves you time and prevents costly mistakes.
Choosing the wrong entity can lead to higher taxes, missed deductions, and even compliance issues. For example, staying a sole proprietor when you could benefit from an S Corp could cost you thousands in unnecessary taxes. That’s why we help you make the right choice upfront and adjust if your business grows into a different structure later.
While you can file basic paperwork on your own, having an accountant ensures your entity choice is aligned with your tax strategy. At Fortitude, we go beyond filing forms—we build a tax plan around your entity type so you start strong and stay compliant.
Yes! Fortitude Tax & Accounting is based in Stansbury Park, Utah, but we serve new business owners nationwide. We help entrepreneurs across the U.S. evaluate their entity options, handle filings, and integrate bookkeeping and tax planning for long-term success.
