The Washington Personal Property Listing (Form REV 64 0012) is the annual report every business, farm, and equipment owner in Washington files with the county assessor to declare taxable personal property used in a business as of January 1 each year. You file it with the assessor in the county where the property sits, not with the state, even though the Washington Department of Revenue prints the standard form.
If you miss the April 30 deadline or skip a single asset, the assessor can add a penalty of 5% per month, up to 25%, under RCW 84.40.130. Washington counties process more than 250,000 personal property listings each year, and county audit reports show roughly 1 in 7 listings get corrected by the assessor for missing assets, wrong cost basis, or skipped supplies.
Here is what you will learn in this guide:
- 📋 What the listing is, who must file, and how Washington’s 39 county assessors handle it
- 🗂️ The exact documents and numbers to gather before you open the form
- ✍️ A line-by-line walkthrough of every box, schedule, and signature on REV 64 0012
- 👥 Three full scenarios showing real filers (a coffee shop, a dental practice, a farm) finishing the form
- ⚖️ The penalties, exemptions, and audit triggers that decide whether you pay fairly or overpay
What the Form Is and Who Must File It
The Washington Personal Property Listing is the sworn annual statement of taxable personal property owned, leased, rented, loaned, or controlled by a business on January 1 of the assessment year. The form covers machinery, equipment, furniture, fixtures, supplies, leasehold improvements, and certain leased items used to produce income. It is required by RCW 84.40.040, which orders every person to list all taxable personal property each year.
You must file if you own or use personal property in a trade, business, or income-producing activity in Washington. That includes sole proprietors, LLCs, partnerships, S-corps, C-corps, farms, nonprofits with taxable assets, landlords who furnish rental units, contractors who store tools in the county, and out-of-state companies with equipment located in Washington. Even hobby-level side businesses fall in scope once they cross into commercial use.
Households do not file for personal-use items like home furniture or family cars, because Washington exempts most household goods under RCW 84.36.110. Farm machinery used in commercial agriculture is taxable but may qualify for the farm machinery exemption under RCW 84.36.630. The assessor in your county, such as the King County Assessor, administers the form, but the Washington DOR Property Tax Division writes the rules in WAC 458-12.
The current statewide template is REV 64 0012 (most recent revision shown on the form’s footer; confirm the year before filing). Many counties, including Pierce, Snohomish, and Spokane, publish their own version of the same form, sometimes with extra schedules for leasehold improvements or idle equipment.
Before You Start: Documents and Information You Need
Personal property listings are won or lost in the prep stage. Pull the following before you open the form, because a missing document almost always turns into a guessed number, and a guessed number almost always turns into an over-assessment.
- Federal depreciation schedule (IRS Form 4562 and the detailed asset register). This is your master list of every fixed asset, its acquisition year, and its original cost. Without it, you will under-report and trigger an audit.
- Prior-year personal property listing. The assessor expects continuity. Missing assets that appeared last year is the single biggest red flag in the DOR personal property audit manual.
- Fixed asset register from your accounting software (QuickBooks, Sage, NetSuite). Match it line by line to the depreciation schedule.
- Lease agreements for equipment. Leased copiers, forklifts, medical devices, and POS systems must be reported even though you do not own them, under WAC 458-12-060.
- Supply purchase records for the prior 12 months. Schedule A asks for the average value of supplies on hand, not the year-end balance.
- Leasehold improvement invoices. Built-in cabinets, walk-in coolers, and partitions installed in leased space are taxable to the tenant.
- EIN, UBI (Unified Business Identifier), and county tax account number. The UBI ties the listing to your Washington business license.
- NAICS code. The assessor uses it to apply the correct industry depreciation schedule from the DOR Personal Property Valuation Guidelines.
- Disposal log for assets sold, scrapped, or moved out of the county. Without proof, the assessor assumes the asset is still there.
- Idle and ghost asset list. Assets you no longer use but still own are taxable until disposed of in writing.
If any item is missing, stop and gather it. Filing with gaps almost always costs more than filing a few days late under an extension.
Where to Get the Form and How to Access It
The statewide template lives on the Washington DOR forms page under the title Personal Property Listing Form, REV 64 0012. You can download it as a fillable PDF. Most counties mail a pre-printed version with your account number to every business that filed the prior year, usually in late December or early January.
If you did not get a mailed copy, go to your county assessor’s website. King County uses the eListing online portal, which lets you log in with your account number and access PIN, roll forward last year’s assets, and submit electronically. Pierce, Snohomish, Clark, Thurston, Spokane, and several other counties offer similar portals. Smaller rural counties still rely on paper.
A new business that has never filed must request an account by contacting the county assessor directly. In King County, you call the Personal Property Section at 206-296-5126 or email personal.property@kingcounty.gov. In Pierce County, you reach the Assessor-Treasurer’s office for a new account number before you can file.
A common misconception is that filing the Washington business license application automatically registers you for personal property. It does not. Personal property is administered by the county, not the state, and the county must open the account separately.
Step-by-Step: How to Fill Out REV 64 0012 Line by Line
The form is organized into a header (taxpayer information), a certification block, Schedule A (supplies), Schedule B (machinery, equipment, furniture, and fixtures by year of acquisition), a leased equipment schedule, a leasehold improvement schedule, and a signature block. Walk through it in the order printed on the form, because the assessor’s data entry follows the same order.
Account Number and Tax Year
The account number is the unique ID the county assessor assigned to your business. It is printed in the upper right corner of any pre-printed listing. New filers leave it blank and let the assessor assign one.
Enter the number exactly as printed, including dashes if shown. Maria Lopez, owner of Cedar Coffee in Seattle, writes 123456-7 in the account number box. The tax year is the year of assessment, not the year you are filing in; for a January 1, 2026 assessment, you write 2026.
A common edge case is a business with multiple locations in different counties. Each location needs its own account number with that county’s assessor. The mistake of combining them onto one listing causes a misallocation of value, and the second county will issue a separate assessment plus penalty. The misconception filers carry is that one listing covers the whole state. It never does.
Legal Name of Owner
Write the exact legal name on file with the Washington Secretary of State for entities, or the legal name on the business license for sole proprietors. Use all caps if the form is pre-printed in caps.
Maria’s coffee shop is registered as Cedar Coffee LLC, so she writes CEDAR COFFEE LLC, not Cedar Coffee. If you operate under a DBA, the DBA goes in the next field, not here.
The nuance is single-member LLCs. Even if the IRS treats them as disregarded entities, Washington counties want the LLC name, not the member’s personal name. The mistake of using a personal name when an LLC owns the assets causes mismatched records, and the assessor may double-list the property under both names. The misconception is that DOR’s UBI database auto-corrects names. It does not. The assessor types what you write.
DBA / Trade Name
This is the name customers see on the door, the website, and the receipts. It often differs from the legal entity name.
Cedar Coffee LLC operates as “Cedar & Steam,” so Maria writes CEDAR & STEAM. Leave it blank only if the legal name and trade name are identical.
The edge case is multiple DBAs under one legal entity. List the DBA tied to this specific location. The mistake is mixing DBAs across locations, which makes it impossible for the assessor to tie audit findings to the correct site. The misconception is that the DBA controls the legal liability for the tax. It does not; the legal entity does.
Mailing Address and Property Location Address
The mailing address is where the assessor sends the assessed-value notice and the tax bill. The property location is where the assets actually sit on January 1.
Write the mailing address as it appears on your most recent piece of business mail. Maria writes PO Box 4412, Seattle, WA 98104 for mailing and 1422 Pine St, Seattle, WA 98101 for the property location. If both are the same, write the street address in both boxes; never leave the location box blank.
The nuance is mobile equipment, like food trucks or contractor trailers, that moves between counties. Washington uses the situs as of January 1 rule under RCW 84.40.020. Wherever the asset was on January 1 controls. The mistake of listing a moving asset’s “usual” location instead of its January 1 location creates a dual-county claim. The misconception is that you can choose the friendlier county. You cannot.
UBI Number and Federal EIN
The UBI is the 9-digit Unified Business Identifier from your Washington business license. The EIN is your 9-digit IRS employer identification number.
Maria writes 602 345 678 for the UBI and 87-1234567 for the EIN. Sole proprietors without an EIN use their Social Security Number, but should ask the assessor whether the county will accept it without redaction.
The edge case is a brand-new business that has applied for but not received a UBI. Write PENDING and attach a copy of the application. The mistake of leaving the UBI blank delays processing and can push your filing past April 30. The misconception is that the UBI and EIN are interchangeable. They are not; the county uses both to cross-reference DOR and IRS data.
Nature of Business and NAICS Code
Describe what the business does in one short phrase, then enter the 6-digit NAICS code that matches.
Maria writes “Coffee shop and bakery” with NAICS 722515. The code drives which depreciation table the assessor pulls from the DOR Valuation Guidelines.
A common nuance is mixed-use businesses. A coffee shop with a small retail bookshelf is still 722515, because the dominant activity controls. The mistake of choosing a NAICS code with a longer depreciation life than your industry actually uses leaves value on the books for years past its real economic life. The misconception is that the code does not matter because the assessor “knows” the business. The assessor follows the code you write.
Date Business Started at This Location
Enter the month and year you opened at this address, not the date the entity was formed.
Maria opened Cedar & Steam at 1422 Pine on 06/2022, so she writes 06/2022. If you bought the business from a prior owner, write the date you took control, not the prior owner’s start date.
The edge case is a relocation within the same county. Use the date you started at the new address, and attach a note explaining the move so the assessor closes the prior site’s account. The mistake of using the entity formation date causes the assessor to assume assets existed for years that they did not. The misconception is that this field is informational. It is not; it shapes the audit window.
Schedule A — Supplies
Schedule A asks for the average value of supplies on hand during the year, not the January 1 snapshot. Supplies include office supplies, cleaning supplies, packaging, fuel, lubricants, parts, and any consumable not held for resale.
Add up monthly supply balances from your accounting records and divide by 12. Cedar Coffee’s average monthly supply balance was $3,400, so Maria writes 3,400 in Schedule A. If you do not track monthly, take the average of beginning and ending inventory of supplies.
The nuance is items that look like supplies but are inventory for resale, like coffee beans Maria sells in bags. Inventory for resale is exempt from personal property tax under RCW 84.36.477 and goes on no schedule. The mistake of writing the year-end balance, which is often near zero after the December push, lowballs the number and triggers an audit adjustment. The misconception is that supplies under $200 are too small to count. The schedule has no de minimis floor.
Schedule B — Machinery, Equipment, Furniture, and Fixtures by Year of Acquisition
Schedule B is the heart of the listing. List original cost, including freight, sales tax, and installation, grouped by the year acquired. Do not enter depreciated book value. Do not subtract Section 179 deductions. The assessor applies its own depreciation table.
Pull each asset from your depreciation schedule and put it in the row that matches its acquisition year. Maria has an espresso machine bought in 2023 for $14,500, a refrigerator from 2022 for $3,200, and a POS from 2024 for $2,100, so she enters 2,100 on the 2024 row, 14,500 on the 2023 row, and 3,200 on the 2022 row. Enter totals only; the assessor does not need each invoice unless audited.
The nuance is fully depreciated assets still in use. They stay on Schedule B at original cost until physically disposed of, regardless of book value. The mistake of dropping a fully depreciated asset because “it’s worth nothing” is the most-cited error in the DOR audit manual, and the penalty under RCW 84.40.130 is up to 25%. The misconception is that bonus depreciation or Section 179 reduces personal property tax basis. It does not.
Leased Equipment Schedule
If you lease equipment from a leasing company, you report the equipment here, not on Schedule B. Provide the lessor’s name, address, equipment description, lease start date, monthly payment, and either the original cost (if known) or the lease term and residual.
Cedar Coffee leases a commercial dishwasher from Ecolab Finance starting 03/2024 at $185/month, so Maria writes Ecolab Finance, dishwasher, 03/2024, $185/month, original cost $9,800. The county will usually tax the lessor and remove the asset from your account, but only if you list it.
The edge case is a capital lease that converts to ownership at the end of the term. Once title transfers, move it to Schedule B in the year of transfer. The mistake of skipping leased equipment because “the leasing company already pays” can result in double assessment, because the county cannot match accounts without your disclosure. The misconception is that operating leases are exempt. They are not; only the party taxed changes.
Leasehold Improvements
Leasehold improvements are alterations a tenant makes to leased space that cannot be removed without damage, like built-in cabinets, partition walls, walk-in coolers, and special wiring. List them by year of installation at original cost including labor.
Maria installed a $22,000 walk-in cooler in 2023, so she writes 22,000 on the 2023 row of the leasehold improvement schedule. Movable items, like a refrigerator on wheels, do not belong here; they go on Schedule B.
The nuance is improvements paid for by the landlord but used by the tenant. If the tenant retains the right to remove or use the improvement, the tenant lists it. The mistake of ignoring leasehold improvements because “they are part of the building” is common; the building is real property assessed separately, but the improvements made by the tenant are personal property. The misconception is that leasehold improvements roll off when the lease ends. They roll off only when removed or when the lease term ends and ownership transfers.
Disposals, Sales, and Transfers
Many listings include a Disposals section asking which assets from last year’s filing are gone. Enter the description, original cost, year acquired, date disposed, and method (sold, scrapped, traded, moved out of county).
Maria scrapped a broken grinder she bought in 2020 for $1,200, on 09/15/2025, so she writes Mazzer grinder, $1,200, 2020, 09/15/2025, scrapped. Keep the proof (junk receipt, bill of sale, photos) for at least three years.
The edge case is assets moved to another Washington county. They are still your assets; you must add them to that county’s listing on the same date you remove them here. The mistake of removing an asset without proof gives the assessor grounds to add it back plus penalty. The misconception is that “scrapped” needs no documentation. It absolutely does.
Certification and Signature
The form ends with a sworn certification under penalty of perjury that the listing is true and complete. Sign, print your name, list your title, and date the form.
Maria signs as Maria Lopez, Member, 04/12/2026. A paid preparer (CPA or bookkeeper) signs in a separate preparer block if the county form has one.
The nuance is electronic signatures on county portals. King County’s eListing accepts an e-signature tied to the login PIN; some smaller counties still want a wet signature. The mistake of signing on behalf of a business without authority can void the listing and expose the signer to perjury exposure under RCW 9A.72.020. The misconception is that an unsigned listing is “still on file.” It is not; assessors treat unsigned listings as non-filings.

How to File the Completed Form
Washington counties accept several filing channels, and the right one depends on your county. Pick one channel and stick with it; mixing paper and online for the same year confuses the assessor and risks duplicate assessments.
- Online portal. King County uses the eListing portal. Pierce uses eFile. Snohomish, Clark, Thurston, and Spokane offer similar portals. There is no fee. Processing takes 2–6 weeks. Your proof is the on-screen confirmation number and the email receipt; save both.
- Mail. Send the signed paper form to the county assessor’s address printed on the form. King County’s mailing address is King County Assessor, Personal Property, 201 S Jackson St, Room 708, Seattle, WA 98104. There is no fee. Processing takes 4–8 weeks. Use USPS Certified Mail with Return Receipt as your proof of filing. The postmark date controls under RCW 1.12.070.
- In person. Most county assessor offices accept hand delivery during business hours. There is no fee. Ask for a date-stamped copy of the first page as proof.
- Fax. Some smaller counties still accept fax. There is no fee. Keep the fax confirmation page as proof, and follow up with a phone call to confirm receipt.
- Email. A handful of counties accept signed PDFs by email. Confirm with the assessor before using this channel; not every county treats email as a valid filing.
The deadline is April 30 every year. If April 30 falls on a weekend or holiday, the deadline rolls to the next business day under RCW 1.12.070. Extensions are available in writing in many counties if requested before April 30.
What Happens After You File
The assessor reviews your listing, applies the DOR depreciation tables, and mails a Notice of Value in late spring or summer. The notice shows the assessed value the county will use to compute your tax bill.
You have 30 days from the date of the notice to appeal to the county Board of Equalization under RCW 84.40.038. Appeals are filed on a separate petition form and require evidence — typically a depreciation schedule, an independent appraisal, or a market quote showing the assessor’s value is too high.
The tax bill itself comes from the county treasurer the following February, with first-half due April 30 and second-half due October 31. A late-filed listing can also draw a 5% per month penalty up to 25% under RCW 84.40.130, and a willful failure to list can draw a separate 25% penalty plus possible criminal exposure.
If the assessor suspects under-reporting, an audit notice can arrive any time within three years of the assessment date under RCW 84.40.085. Audits typically request the full depreciation schedule, fixed-asset register, and lease agreements for the audit period.
Mistakes to Avoid When Filling Out the Form
- Dropping fully depreciated assets. They stay listed at original cost until disposed of; removing them triggers audit adjustments and penalties.
- Reporting net book value instead of original cost. Schedule B uses original cost; using book value under-reports and almost always triggers a recomputation.
- Skipping leased equipment. The county taxes someone for it; missing it from your listing delays the lessor’s account and can result in your account being charged.
- Mixing inventory for resale with supplies. Resale inventory is exempt; supplies are not. Combining them inflates your bill.
- Forgetting leasehold improvements. Tenants forget that built-ins are personal property. The assessor finds them on building permits and adds them later, with penalty.
- Listing the wrong NAICS code. The wrong code applies the wrong depreciation life and can keep value on the books for extra years.
- Missing the April 30 deadline. Even one day late starts the 5% per month penalty under RCW 84.40.130.
- Filing in the wrong county. Personal property is taxed where it sits on January 1, not where the business is headquartered.
- Using personal name instead of LLC name. This causes double-listing and correspondence errors that take months to fix.
- Skipping the disposal section. Without proof, last year’s assets stay on this year’s roll.
- Forgetting idle or stored equipment. Assets in storage are taxable until disposed of.
- Leaving the signature line blank. Unsigned listings are treated as non-filings and draw the same penalty as no filing at all.
Do’s and Don’ts
- ✅ Do roll forward last year’s listing and adjust, rather than start from scratch, because the assessor compares year-over-year.
- ✅ Do keep a paper or PDF copy of every filing for at least seven years, because audits can reach back three years and assessments can stretch further with willful non-filing.
- ✅ Do report leased equipment with the lessor’s full name and address, because the county uses that to match the lessor’s account.
- ✅ Do file even if you have no assets, by submitting a “no property” listing — silence looks like non-filing.
- ✅ Do request an extension in writing before April 30 if you need more time; many counties grant 30 days.
- ✅ Do reconcile Schedule B to your federal depreciation schedule line by line; mismatches are the top audit trigger.
- ❌ Don’t subtract Section 179 or bonus depreciation; the assessor uses original cost.
- ❌ Don’t combine multiple locations into one listing; each county and each location needs its own.
- ❌ Don’t drop assets just because they are old; age does not equal disposal.
- ❌ Don’t use book value anywhere on Schedule B; the form expects original cost.
- ❌ Don’t sign on behalf of an entity without written authority; the certification is sworn under perjury.
- ❌ Don’t assume the assessor will catch errors in your favor; assessors round up far more than they round down.
Pros and Cons of Filing on Your Own vs. With Help
- ✅ Pro — DIY saves money. A small business with under $50,000 in equipment can finish the form in 2–3 hours.
- ✅ Pro — DIY teaches the books. Owners who file their own listing learn what assets they actually own.
- ✅ Pro — Professional help reduces audit risk. A CPA who files dozens of listings spots NAICS and depreciation issues quickly.
- ✅ Pro — Professional help finds exemptions. Farm machinery, head-of-family, and pollution control exemptions are easy to miss.
- ✅ Pro — Professional help carries malpractice coverage. A CPA’s E&O policy backs the work; DIY does not.
- ❌ Con — DIY risks under-reporting penalties. Owners who guess often guess low and trigger 5–25% penalties.
- ❌ Con — DIY takes time during tax season. April 30 overlaps with federal returns.
- ❌ Con — Professional help costs $300–$1,500 per location. Small shops feel the fee more than mid-size practices.
- ❌ Con — Professional help still needs your data. A CPA who gets bad inputs files bad outputs.
- ❌ Con — Switching preparers loses institutional memory. A new preparer may miss assets a prior preparer tracked informally.
Paper vs. Online Filing
| Factor | Paper Listing |
|---|---|
| Submission speed | Slow; mail takes days |
| Proof of filing | Certified mail receipt and postmark |
| Error correction | Requires a written amendment |
| Best for | Counties without portals, complex listings with attachments |
| Factor | Online Listing |
|---|---|
| Submission speed | Instant; confirmation email in minutes |
| Proof of filing | On-screen confirmation number and email |
| Error correction | Edit through the portal until the deadline |
| Best for | Repeat filers with stable asset lists |
Key Agencies, Statutes, and Programs
The Washington Department of Revenue writes the rules and publishes the form, but the county assessor runs the listing process and the county treasurer issues the bill. The State Board of Tax Appeals hears appeals beyond the county Board of Equalization. The governing statutes are RCW 84.40 (listing and valuation), RCW 84.36 (exemptions), and WAC 458-12 (administrative rules).
A common misconception is that personal property tax was repealed when Washington raised the head-of-family exemption to $15,000 under RCW 84.36.110. It was not; the exemption only covers the first $15,000 of value for qualifying filers, and businesses still file even when they owe nothing.
FAQs
Do I have to file if my equipment is worth less than $15,000?
Yes. You still file the listing. The $15,000 head-of-family exemption under RCW 84.36.110 reduces the tax, not the duty to file. Skipping the filing still triggers penalties.
Do I write original cost or book value on Schedule B?
Yes — original cost only. Include freight, sales tax, and installation. Do not subtract depreciation, Section 179, or bonus depreciation. The assessor applies its own depreciation schedule.
Do fully depreciated assets still go on the listing?
Yes. Assets stay on Schedule B at original cost as long as you still own them, even if their book value is zero. Removing them without disposal proof triggers audit penalties.
Do I list leased equipment in Schedule B?
No. Leased equipment goes on the separate Leased Equipment Schedule with the lessor’s name, address, lease start, and monthly payment, not on Schedule B.
Do I report inventory I sell to customers?
No. Inventory held for resale is exempt under RCW 84.36.477. Only supplies consumed in operations go on Schedule A.
Do I file in every county where I have equipment?
Yes. File a separate listing in each county where any taxable personal property sits on January 1. One statewide filing does not exist.
Do I file if I closed the business in December?
Yes. If you owned the assets on January 1 of the prior year and disposed of them after, you still file a final listing showing the disposals. This closes the account.
Do I write my Social Security Number if I have no EIN?
Yes, if you are a sole proprietor without an EIN, but ask the assessor for the redaction policy first. Most counties accept the SSN and redact it from public records.
Do leasehold improvements go on Schedule B or a separate schedule?
No, not Schedule B. Use the Leasehold Improvements schedule and group by year of installation at original cost including labor.
Do I need to attach my federal depreciation schedule?
No, attachment is not required at filing, but the assessor can request it during an audit under RCW 84.40.085. Keep it ready for three years.
Do I lose the right to appeal if I miss April 30?
No. You can still appeal the Notice of Value within 30 days of that notice under RCW 84.40.038, but late filing penalties still apply.
Do farms file the same form as other businesses?
Yes. Farms file REV 64 0012 but may claim the farm machinery exemption under RCW 84.36.630. Supplies, fuel, and shop tools are still listed.
Do I need to list assets stored at home for my business?
Yes. Home-office equipment used in a trade or business is taxable personal property. The location address is your home address if that is where the asset sits on January 1.
Do I file electronically or on paper if I missed the mailed form?
Yes — either works. Download REV 64 0012 from the DOR forms page or use your county’s portal, such as King County eListing. Both filings are equally valid.
