The part that makes it hard
Washington asks more of a contractor’s books than most states do.
None of this is exotic. It’s just a lot of small things that have to be right every month, and most of them have nothing to do with bookkeeping in any other state.
Sales tax follows the job site.
Rates are destination based, so two jobs at the same price a few miles apart owe different amounts. Rates change quarterly. Your invoicing software only knows what somebody typed into it on setup day.
Whether you charge sales tax depends on who hired you.
Working directly for the property owner, you charge sales tax. Working as a sub for another contractor, you don’t, but only if you have their reseller permit on file. No permit means the DOR treats that job as retail, and the tax comes out of your pocket at audit instead of your customer’s.
Nobody invoices you for use tax.
Materials pulled from reseller-permit inventory for your own property, shop supplies, equipment and tools bought out of state. It’s owed, no vendor bills you for it, and it’s the line that most often goes unreported for years.
Rates change while jobs are still open.
Progress payments on a long job routinely straddle a rate change. On cash basis, what you collected months ago and what gets reported now can pull apart, and reconciling that afterward is far harder than getting it right as you go.
The state return isn't the only return.
Seattle, Bellevue, Tacoma, Everett and dozens of other cities levy their own B&O, each with its own registration, thresholds and filing schedule. Some file through FileLocal, some direct. Take a job across a city line and you may owe somewhere you have never filed.
Sales tax and B&O arrive on the same return.
The sales tax portion is money you collected and were holding, so it clears a liability. The B&O portion is a tax on gross receipts, so it’s an expense. One payment leaves the bank and it has to land in two places.
- The rate belongs to the job site, not your shop, and there are hundreds of jurisdictions with rates that move on their own schedule. On top of that, construction has its own rules layered over it. Whether the job is retail or wholesale. Whether the reseller permit is on file. What you owe use tax on. Which city wants a return.
- A bookkeeper who doesn’t file Washington returns every month has no particular reason to know any of that. Nothing in their work flags it, and the errors don’t announce themselves. They accumulate quietly across a year of invoices and surface when the return doesn’t tie.
- That’s most of what we clean up. Not carelessness, just someone working from what’s normal everywhere else. It’s also why we’re not a national service that assigns you whoever is free this quarter and starts over when they leave.
Owner and entity
- Business and personal funds run together, so nothing reconciles cleanly
- Personal spending treated as business expense, or the LLC account used as a personal account without proper draws or distributions
- After an S-corp election, no reasonable salary running through payroll, and owner health insurance reported incorrectly
Sales tax mechanics
- Payments coded straight to income without invoicing, so sales tax was never calculated or separated at all
- Credit card surcharges passed to customers but never taxed
- The DOR payment coded to a single account, so sales tax payable never clears or B&O never hits the P&L
Filing and records
- Accounts not reconciled, so the numbers were never trustworthy to begin with
- Subcontractors paid with no W-9 collected up front and no 1099s filed at year end
- DOR returns unfiled for years, with penalties and interest still accruing
The expensive one
Unfiled DOR returns don’t go quiet. They compound.
Washington adds a late penalty that escalates the longer a return sits unfiled, and interest runs on top of it. A contractor who quietly stopped filing three years ago isn’t carrying one problem. They’re carrying every quarter since, each with its own penalty tier.
This is fixable. We have brought files current, worked back through the unfiled periods, and put clients back on a filing schedule they can actually keep. It isn’t comfortable and it isn’t free, but it stops getting worse the day you start.

What you actually get
What a month looks like.
The same rhythm every month, so you always know where things stand.
We work the file
Transactions categorized, accounts reconciled, invoicing and sales tax checked against the jobs they belong to. If something doesn’t look right, you hear from us then, not at year end.
Filings prepared and submitted
Your monthly DOR return prepared, filed and paid on schedule, plus any city B&O you owe, with the payment split correctly between liability and expense in your books.
You get a closed month
Financials your CPA can use without rebuilding them, and a bookkeeper who can tell you why anything on them looks the way it does.
What we don’t do
- Tax returns – Your CPA keeps those. We hand them clean books and stay out of the way.
- Construction CFO work – No WIP schedules, AIA billing or certified payroll. Most contractors your size don’t need it, and we’d rather tell you that than sell it.
- Guarantees about the DOR – We can get your filings right and your records defensible. Nobody can promise you’ll never hear from them.
