St. Louis CPA Services That Bring Clarity to Your Business
Most St. Louis firms are one of two things: big regional shops with $20,000-a-year minimums, or solo preparers who file the April return and disappear until March. There’s a real gap in the middle, and we built the firm to live in it.
Thompson Flaherty is an Illinois and Missouri-licensed CPA firm fifteen minutes from downtown, working year-round with small businesses and families across St. Louis, Clayton, and St. Charles County.
What a St. Louis CPA Actually Does for a Small Business
The work splits into three categories. A firm that only does one of them is leaving you exposed on the other two.
Missouri and Illinois Together, Which Most St. Louis Firms Can’t Do
The genuinely useful thing about a CPA sitting on the Illinois side of the river is that the metro doesn’t respect the state line, and neither do our licenses.
We work with an owner whose company is registered in Missouri, whose warehouse sits in Illinois, and whose employees live on both sides. That’s two state returns, apportionment between them, withholding into different states, and a city earnings tax question underneath it all. Handled well, it’s routine. Handled by two firms that don’t talk to each other, it turns into amended returns.
The city’s 1% earnings tax reaches anyone living in St. Louis city whatever their employer’s location, and anyone employed by a business inside the city whatever their home address. It’s the item we most often find missed on a new client’s prior-year filings, and we walk through it in our breakdown of the St. Louis earnings tax.
What Does a CPA Cost in St. Louis?
Pricing should be a number, not a mystery. Here’s roughly where our St. Louis clients land.
We quote a real number after a 30-minute intro call, and we’d rather tell you we’re not the right fit than talk you into a package you don’t need.
We Do Things Differently Than Most St. Louis Accountants
Most firms are built around volume. File the return, move to the next client, get through tax season. That works until you actually need help. Here’s what you get with us instead.
Why St. Louis Clients Choose Thompson Flaherty
We’re not a high-volume tax shop. Every client works directly with a dedicated CPA who handles both the tax work and the ongoing advice throughout the year. And we’ll tell you honestly when something isn’t the right move, even when the alternative carries a higher fee.
Our services start at $550 for a basic return, reflecting the level of care, attention, and strategy we bring to every client.
Serving the Whole St. Louis Region
Most engagements run virtually, so the relationship looks the same whether you’re in the Central West End or out past Wildwood. When it’s worth meeting face to face, the drive from Edwardsville is short.
When Should a St. Louis Business Hire a CPA?
There’s no revenue number that applies to everyone, but a few moments where owners reliably outgrow doing it themselves.
If two or more of those describe your year, the conversation is worth having now rather than in March.
