One Valley. Two Tax Systems. CPA Support for Clarkston Businesses and Cross-River Households.
Clarkston businesses and households are tied closely to Lewiston and the Idaho side of the valley. That creates state-specific tax, payroll, and bookkeeping issues that should be planned before filing season.
Clarkston storefronts owe Washington B&O on gross receipts and retail sales tax on delivered goods even when most customers live in Lewiston. Misclassifying services as non-taxable or shipping inventory from Idaho without use-tax accrual produces assessments that dwarf the monthly compliance cost you skipped.
Bench orchards and grain operators in Asotin County still face federal Section 179, prepaid input expenses, deferred crop insurance reporting, and Schedule J averaging - while Washington adds B&O on marketed crops and custom work. Federal and state filings need one coordinated calendar before harvest checks arrive.
Households domiciled in Washington while earning Idaho wages from Lewiston hospitals or valley employers must reconcile Idaho withholding against Washington residency, plus any Idaho rental or K-1 income on the east side of the river. Filing each state in isolation routinely double-counts or drops credits.
Clarkston sits on the Washington bank of a valley that runs on river trade, Asotin County agriculture, and daily commerce with Lewiston - which means our clients here live in one state's tax system while their money often earns in another.
Washington B&O registrants on Bridge Street and the commercial corridor who sell to Idaho buyers, run Idaho deliveries, or hire across the river and need sales tax and payroll documented before an audit letter arrives.
Wheat, pulse, orchard, and vineyard-adjacent businesses on the Washington benches who manage equipment purchases, seasonal crews, crop revenue swings, and lender-ready books behind every financing decision.
Restaurants, motels, and retail operators serving river traffic and Lewiston commuters who manage Washington sales tax, tip reporting, and payroll through event weekends and quieter winter weeks.
HVAC, electrical, plumbing, and fleet contractors running jobs in Clarkston, Lewiston, and rural Asotin County who need mileage, job profitability, and worker classification handled during the season.
Families with Washington domicile and Idaho wages from Lewiston employers, hospital systems, or valley industry who need withholding credits, rental income, and side business income coordinated on one plan.
Washington-side storage, cold-chain, and transfer businesses tied to Palouse grain movement who need inventory, depreciation, and B&O treatment aligned to how freight actually moves through the valley.
Clarkston clients get a clear process built around the full LC Valley picture: where income is earned, which filings are required, and what the books say before decisions are made.

“I thought my CPA was doing a decent job until I switched to Kane Tax and Accounting. They found tax strategies nobody had ever brought up and saved my business way more money than I expected. Tax planning is clearly what they do best and it has made a huge difference for my bottom line.”
“Collin is one of the best in the area! His communication is on point and makes things easy for business owners to understand while they’re trying to scale their business. He’s helped our business move forward and has freed up time for us to continue to do what we do best as he takes over areas in his expertise. I highly recommend Collin for any business owner in the area.”
“Great experience with Collin. I was sick and tired of my families accountant and needed someone who would take the time to explain things & he did just that.”
Clarkston sits across the Snake River from Lewiston, forming the Washington side of the Lewis-Clark Valley. Daily life and business activity move across the river constantly, but tax systems do not merge as neatly as the local economy does.
Washington businesses need to understand B&O tax, sales tax, payroll filings, and state registration even though Washington does not impose individual income tax. Those rules are easy to overlook when a company is focused on operations and Idaho customers are part of the mix.
Clarkston households often have Idaho connections: employment in Lewiston, rental property across the river, business customers in both states, or investments that touch multiple jurisdictions. Coordinating those facts before the return is prepared can reduce confusion and cleanup.
The local economy includes hospitality, trades, healthcare, retail, logistics, agriculture-adjacent services, and professional offices. Each industry has different bookkeeping and tax needs, from payroll classification to inventory, mileage, depreciation, and sales tax documentation.
Cash flow can be seasonal or project-based in the valley. Owners who wait until year-end to reconcile books often miss estimated payment windows, underprice work, and make hiring decisions without knowing real margins.
Kane Tax & Accounting serves Clarkston clients remotely with secure digital tools and direct CPA planning. The firm is built for clients who want practical guidance across Washington and Idaho - filings, books, payroll, and the planning that connects them.
Whether you operate a service company, manage rentals, run a restaurant or shop, or need personal tax planning around multi-state income, we provide tax preparation, bookkeeping, payroll, and advisory support.
For Clarkston clients, the goal is simple: keep the records clean, understand both state tax systems, and make decisions before deadlines force a rushed answer.

Both. We are based in Coeur d'Alene and meet clients in person for planning sessions and year-end reviews, but most ongoing work happens over secure document sharing and Zoom.

Yes. Many of our clients are business owners who want one firm handling the business return, their personal return, bookkeeping, and payroll so nothing falls through the cracks. We also work with individuals who just want their personal taxes done right by a CPA. We will tell you honestly which services fit your situation.
It depends on your margins, and neither side is automatically cheaper. Washington has no income tax but charges a Business and Occupation tax on gross receipts, which you owe even in a year you lose money. Idaho taxes business profits instead. For a low-margin business the Washington B&O tax can bite harder; for a high-margin one, Washington's no-income-tax structure can come out ahead. We model both sides for your actual numbers.
Most likely yes. The B&O tax applies to gross receipts, not profit, and normal expenses like payroll, rent, and materials do not reduce it the way deductions reduce income tax. The rate depends on your business classification. Because it is built so differently from federal tax, it catches a lot of Clarkston owners off guard, which is why it helps to have a CPA who files both states.
Yes, and this surprises people. Because the tax is on gross receipts rather than net income, you can have a break-even or loss year and still owe it. We build that into your planning through the year rather than leaving it to filing season.
If you are a Washington resident working in Lewiston, Idaho taxes the income you earn from Idaho sources and you file an Idaho nonresident return. If you are an Idaho resident working in Clarkston, Idaho taxes your income and Washington does not tax wages. Getting the sourcing right is where we help.
Possibly. Selling into both Idaho and Washington can create a collection obligation in each, depending on where and how you do business. Washington also ties sales tax filing to B&O filing. We sort out where you have an obligation so you are collecting and remitting correctly in both states.
Yes. That is the norm in the valley. Customers cross the bridge both ways, which affects sales tax, B&O classification, and how income gets sourced. We set up your reporting so serving both sides does not create a filing mess.
When your business serves both sides of the river, payroll and B&O filings are running, and the questions shift from whether books are accurate to whether you can afford the next hire, a second location, or a heavy equipment purchase without choking cash flow. Fractional CFO work is for Clarkston owners who need projections, job-level profitability, and a written plan before they commit - especially when Washington gross-receipts tax means a bad timing decision hurts even in a profitable year.
Yes. Valley businesses often have crew members living on different sides of the river. We set up withholdings, workers comp, and state unemployment filings correctly for Washington employees, coordinate Idaho resident issues where they affect your employees' returns, and keep payroll tax deposits on schedule so B&O and sales tax filings stay tied to clean wage records.
