Quick answer
Who handles accounting for small businesses in the Flathead Valley?
406 Consulting Group is a Flathead Valley firm, based in Columbia Falls, that handles bookkeeping, payroll, business and personal tax, controller reporting, and fractional CFO work for businesses across the Flathead Valley — Kalispell, Whitefish, Columbia Falls, Bigfork, Lakeside, and around the lake. You work directly with the two founders, in person at our Columbia Falls office or by phone and video, as one connected team instead of a separate bookkeeper, tax preparer, and advisor.
What changes when we take over
Stop guessing. Know where your money is — every month.
Most valley owners we meet are good at their trade and buried in the paperwork. The books are a few months behind, the tax bill is a surprise every spring, and the busy season hides whether the year actually made money. That gap costs real dollars: missed deductions, a loan that takes three extra months, a bid priced below cost.
Here’s what you get instead:
- Books closed and reconciled every month — you know your real profit, not just your bank balance
- Taxes planned during the year, with no April surprises
- A cash plan that carries you through the slow season
- Financials a lender can approve, ready before you need the loan
- A founder who picks up the phone and can meet you in person in Columbia Falls

We live here too
Built for how business actually works in the Flathead
A big-city firm sees a tax return. We see a valley where summer pays for winter, contractors race the snow, and half the lake shore is a short-term rental. That context changes the advice.
Summer pays for winter
Tourism, lake traffic, and the building season pack most of the valley's revenue into a few months. We plan the whole year so January payroll and spring taxes aren't a scramble.
Building and remodeling boom
Contractors here juggle short seasons, rising costs, and bank draws. We set up job costing that shows which jobs actually made money — while there's still time to fix the next bid.
Lodging and resort taxes
Short-term rentals and lodging owe Montana's 8% lodging taxes, and Whitefish businesses also collect its 3% resort tax. We keep the filings and the pricing math straight.
Equipment-heavy businesses
Excavation, logging, ag, and outfitting carry big equipment lists. Above $1 million statewide, Montana's business equipment tax applies — we track it and plan purchases around it.
Healthcare and professional firms
Practices and firms that grow around Logan Health and the valley's professional base need clean payroll, entity planning, and owner-pay strategy, not just a tax return.
Owners who are the business
Most valley companies are owner-run. We give you the numbers and the plan a CFO would, so decisions about hiring, buying equipment, or borrowing aren't guesses.
Joe’s Excavation, Columbia Falls: a great August, a scary February
Joe runs two excavators and a crew of five. From May to October he’s booked solid and the bank account looks great. Then the ground freezes. By February he’s covering payroll for his best operator, an equipment payment, and a property tax bill with almost nothing coming in — and his tax preparer just told him he owes more than he set aside.
Step 1
Close the books monthly
Joe sees profit by job, not just a bank balance.
Step 2
Build a 12-month cash plan
Summer cash gets set aside for winter costs and taxes.
Step 3
Plan taxes in the fall
Time equipment buys and owner pay before year-end.
The result: February is boring. Payroll clears, the tax bill matches the plan, and Joe can decide on his next machine with real numbers in front of him.

Who You’re Actually Working With
Two founders who’ve sat on both sides of your financials
Your Flathead Valley accountants are also your neighbors. You aren’t handed off to a junior bookkeeper. You work directly with the people whose names are on the door — and their backgrounds are exactly the ones a growing business needs in its corner.

Carrie Anderson
Co-Founder · The Lender’s Eye
A former corporate controller and the contracted commercial loan analysta Montana community bank relies on — she has spread, packaged, and recommended 300+ commercial loans. She knows exactly how a bank reads your financials to decide what you can borrow — because she’s the one doing that analysis. That’s why our clients’ books come out lender-ready, not just tax-ready.

Jason Anderson
Co-Founder · The Operator’s Eye
A degreed accountant with 10+ years in tax and a decade of enterprise operations and accounting at BP, with a lifelong discipline for process, efficiency, and Six Sigma— made practical, not academic. He builds the job costing, tax strategy, and systems that let a company actually see where its money goes and scale without the wheels coming off.
Both spent years in the oil & gas industry, and both design financial systems from a whole-company view— not just an accounting lens. You get a firm that reads your numbers like a lender and builds systems like an operator.
Meet the team“Carrie is amazing. The analysis and the work she does is top tier. I’ve been in operations a long time and I know quality work when I see it.”

Montana has no general sales tax, but it does have a state income tax (for 2026, 4.7% up to $47,500 of taxable income for single filers and 5.65% above that), a 6.75% corporate income tax, an 8% tax on lodging stays, a 3% resort tax inside Whitefish city limits, and a business equipment tax for businesses with more than $1 million of equipment statewide.
