Real Situations. Real Numbers. No Internet Speak.
These aren't case studies from a brochure. They're the kinds of situations we see every week working with Idaho business owners — from framing crews in Meridian to HVAC companies in North Idaho. If any of these sound familiar, that's the point.
When the Bank Says No — And the Books Are Why
Picture a framing crew out of Meridian. Three crews, about $200,000 in revenue, busy enough that the owner is on the job site every day. He goes to his bank for a $50,000 line of credit to cover payroll between draws. The bank says no. Not because the business isn't profitable — it probably is. But the books are a mess. Business expenses are mixed with personal spending. There's no clear separation between the business account and the owner's account. The P&L looks like a disaster even though cash is coming in. This is one of the most common situations we see with small contractors in the Treasure Valley.
When books are mixed with personal spending, a bank can't evaluate the business — so they don't approve it. Clean financials unlock things that messy books never can: a readable P&L that shows true profitability, a balance sheet that supports a credit application, and a clear picture of what the business actually earns. A framing company at $200K with a proper chart of accounts for construction and clean separation between business and personal is a fundable business. The same company with mixed books and no job separation isn't — regardless of how busy the owner is. The work is the same. The financial picture is completely different.

Line of credit — the difference between clean books and mixed ones
The Books Looked Fine. They Weren't.
A client came to us after working with a cheaper bookkeeping service for several years. On the surface, the books looked okay — revenue was being recorded, expenses were being tracked. But when we reviewed the books in detail, we found two problems that had been compounding quietly for years. First: the owner had been making capital contributions to the business — putting their own money in to cover slow months — and those contributions had been coded as revenue. That inflated taxable income every single year. The owner was paying income tax on money they had already paid tax on personally. Second: equipment purchases — a skid steer, a trailer, a work truck — had been coded as owner contributions instead of fixed assets. That meant the business never took the depreciation deductions it was entitled to. Thousands of dollars in write-offs, gone.
“The books looked fine. But they were paying taxes on money they'd already paid tax on — for years.”
When we corrected the coding and reconstructed the proper treatment of those transactions, the picture changed significantly. The owner had been overpaying taxes for years because the books were wrong in ways that aren't obvious unless you know what to look for. A cheaper bookkeeper records what happens. A good one understands what it means — and catches the difference between a capital contribution and revenue, between an asset purchase and an expense. The owner was prepared to keep paying. They didn't have to.
From $500K to $2.5M — Without the Owner Having to Be There Every Day
Here's what a landscaping company at $500,000 in revenue typically looks like: the owner is doing everything — quoting jobs, managing crews, handling customer calls, and trying to keep up with the books on Sunday nights. He knows he's leaving money on the table but doesn't know where. He can't take a vacation. He can't hire a manager because he doesn't know if he can afford one. He is the bottleneck in his own business. This is the most common pattern we see in Boise-area service businesses that are growing but haven't built the financial systems to support the growth.
The path from $500K to $2.5M isn't about working harder — it's about building the financial infrastructure that lets the business run without the owner being the answer to every question. That starts with a real P&L that shows which services are actually profitable. Then a simple dashboard: revenue by service line, labor cost as a percentage of revenue, a 13-week cash flow forecast. With that foundation, an owner can make a decision like 'stop quoting lawn maintenance at competitive rates and focus on irrigation' — because the numbers show irrigation margins at 42% and lawn maintenance at 11%. That's the kind of insight that changes a business.
When the Offer Comes, You Have 3 Weeks or 9 Months
Here's what acquisition readiness actually looks like in practice. A North Idaho HVAC company — 14 technicians, $3.8M in revenue, eight years of steady growth — gets contacted by a regional PE-backed rollup that's been acquiring HVAC businesses across the Mountain West. The owner wasn't actively looking to sell. But the offer was real, and the number was interesting. What happens next depends entirely on one thing: whether the books are already right.
If the financials are clean, auditable, and consistently maintained — three years of management reporting, a WIP schedule, proper job costing — due diligence takes three weeks. If they're not, it takes six to nine months to reconstruct, and half the time the deal falls apart in the process. The difference isn't luck. It's whether the financial foundation was built before the opportunity arrived. This is why Controller-level work matters even when you're not thinking about selling. The business that's ready when the offer comes is the business that built the systems years before anyone called.

Idaho-Specific Expertise.
406 Consulting Group was built in Montana and serves businesses across the Mountain West.

Get in TouchPTET Election Evaluated for Every Eligible Idaho Client
Idaho's pass-through entity tax election is one of the most valuable tools available for S-Corp and partnership owners — and most aren't using it. We evaluate it for every eligible client as part of onboarding, and update the analysis annually as Idaho's income tax rate continues to change.
We Track Idaho's Ongoing Tax Rate Reductions
Idaho's income tax rate has dropped four times since 2021. Each reduction changes the math on the PTET election, S-Corp elections, and income timing decisions. We update our analysis annually so your strategy reflects current law, not last year's rates.
Built for the Treasure Valley Growth Cycle
We've seen the pattern dozens of times: strong revenue growth, financial systems that haven't kept pace, and a business owner making critical decisions without real data. We build the infrastructure that lets you grow without flying blind.
Remote-First, Idaho-Rooted
We serve businesses in Boise, Meridian, Nampa, Coeur d'Alene, Twin Falls, Idaho Falls, Pocatello, Lewiston, and across the state. Cloud-based accounting, video calls, and real-time dashboards mean geography is never a barrier.
What Idaho's Tax Structure Means for Your Business
Idaho has been actively cutting taxes — the income tax rate has dropped four times since 2021. Here's where the real planning opportunities are.
Income Tax: 5.695% (2024) — and Falling
Rate Trending DownIdaho's income tax rate has been cut three times in recent years: 6.5% in 2021, 6% in 2022, 5.8% in 2023, 5.695% in 2024. The legislature has signaled continued reductions. For S-Corp and partnership owners, this is a moving target — your tax strategy should be updated annually to reflect the current rate and any new planning opportunities the reductions create.
Pass-Through Entity Tax (PTET) Election — 5.695%
Most UnderutilizedIdaho's PTET election allows S-Corps and partnerships to pay state income tax at the entity level, making it fully deductible as a business expense on the federal return. This effectively bypasses the federal $10,000 SALT cap. For an Idaho S-Corp owner with $150K in pass-through income, this election can save $2,000–$3,500 in federal taxes annually. Most Idaho business owners are not using it.
Sales Tax: 6% — With Important Exemptions
Exemptions Often MissedIdaho has a 6% state sales tax, but with significant exemptions for manufacturing equipment, agricultural inputs, and certain business purchases. Idaho also exempts most services from sales tax — a meaningful advantage for service businesses. Understanding which purchases qualify for exemption is often overlooked and can represent thousands in annual savings.
Corporate Income Tax: 5.3% Flat Rate
Entity Structure MattersC-Corps pay a flat 5.3% Idaho corporate income tax. For most owner-operated businesses, the pass-through structure remains more tax-efficient — but the right entity choice depends on your revenue, owner compensation, growth trajectory, and exit plans. We evaluate entity structure for every new client.
Idaho Regions We Serve
The Treasure Valley is not the Magic Valley is not the Panhandle. Each region has its own industries and financial dynamics.
Boise & Treasure Valley
Idaho's capital and the economic engine of the state. Boise, Meridian, Nampa, and Caldwell businesses are scaling fast in construction, tech, professional services, and trades. The Treasure Valley has one of the fastest-growing business communities in the country — and most businesses are running financial systems that weren't built for their current scale.
Coeur d'Alene & North Idaho
The Panhandle is in the middle of a construction and hospitality boom. Coeur d'Alene, Post Falls, Hayden, and Sandpoint businesses are growing fast — driven by in-migration, tourism, and a thriving trades economy. Seasonal revenue patterns and rapid scaling are the two most common financial challenges here.
Twin Falls & Magic Valley
The Magic Valley is Idaho's agricultural heartland — but also home to a growing food processing, manufacturing, and professional services economy. Businesses here often have strong revenue but face significant seasonal cash flow challenges tied to harvest cycles and processing contracts.
Idaho Falls & Eastern Idaho
Eastern Idaho's economy is anchored by energy, healthcare, and agriculture. Idaho Falls, Rexburg, and Pocatello businesses tend to be capital-intensive and owner-operated — with banking relationships that require clean, credible financials and a clear financial narrative.
Lewiston & North Central Idaho
Lewiston and the Clearwater region have a strong trades, logistics, and agriculture-adjacent economy. Businesses here often have stable revenue but need better cash flow management, banking readiness, and a tax strategy that keeps pace with Idaho's ongoing rate changes.
Sandpoint & Bonner County
Sandpoint and Bonner County have seen significant in-migration and a construction surge. Businesses here face the same challenges as Coeur d'Alene — rapid growth, seasonal revenue, and financial systems that weren't built for the current scale of operations.

Business Turnaround & Financial Advisory
The Foundation Has to Be Right Before Strategy Matters
Most Idaho businesses have a tax preparer. Very few have clean books, compliant payroll, and real-time financial visibility. That's the foundation we build first — because without it, every other service is built on sand.
Clean Books, Every Month
Idaho's fast-growing economy — construction, agriculture, technology, and professional services — demands accurate, reconciled financials maintained monthly. We use QuickBooks Online or Xero, categorized correctly for your industry, and ready for your bank, your CPA, or your partners whenever they need it.
Idaho Payroll Done Right
Idaho's growth economy means more employees, more complexity, and more compliance exposure. We process payroll accurately and on time, manage Idaho state withholding and unemployment insurance filings, and handle the multi-state payroll issues that come when Idaho businesses expand into Nevada, Utah, or Oregon.
