About Our Firm

MSG Tax & Accounting Inc. was built for small business owners who want more than just once-a-year tax prep. Based in Southern California and serving clients across the Inland Empire, Los Angeles, and Orange County, we offer year-round strategy, guidance, and real partnership, not just compliance.

Our Process

Our firm is led by Manny Singh, a CPA who took everything he learned at a large firm in Irvine and repurposed it for the kinds of business owners who are usually overlooked: self-made, fast-growing, wearing every hat. Whether you’re scaling an e-commerce brand, managing rental properties, driving growth in the trucking industry, or leading a medical practice, we bring clarity and planning to help you take control.

Our core services include:

  • Business and individual tax preparation

  • Subscription-based tax planning and bookkeeping

  • Cash flow management and business consulting

  • IRS audit support (non-attest)

  • Financial statement preparation

  • Retirement and estate/trust tax planning

At MSG, we don’t aim to work with hundreds of clients — we aim to go deep with the right ones. Our ideal relationship is built on a subscription model, combining bookkeeping, planning, and prep throughout the year. It’s better ROI for you, and more rewarding for us.

When he’s not advising clients, you’ll probably find Manny outside — shooting hoops, cheering on the Lakers or Dodgers, or just enjoying the Southern California sun. He didn’t launch this firm to be buried in cubicles. He launched it to help business owners succeed and live more freely.

Let’s take the complexity out of your taxes — and turn it into a strategy that actually works for you.
