Washington Form REV 41 0058 is the Application for Refund or Credit that taxpayers file with the Washington State Department of Revenue to recover overpaid excise taxes such as Business & Occupation (B&O) tax, retail sales tax, use tax, and public utility tax. The form lets a business, consumer, or authorized representative ask the agency to either return the money or apply it as a credit against a future tax bill.
Filing the wrong amount, missing the four-year statute of limitations under RCW 82.32.060, or skipping required attachments can cause an outright denial. The Department of Revenue processes thousands of refund applications each year, and internal DOR data shows that roughly 1 in 5 refund claims is delayed or denied because of missing schedules, math errors, or an unsigned Confidential Tax Information Authorization when a third party files.
Here is what this guide covers:

What the Form Is and Who Must File It
Form REV 41 0058 is the official Washington State application that a taxpayer uses to request a refund or credit of state excise taxes that were paid in error or overpaid. The form is governed by RCW 82.32.060 and the procedural rules in WAC 458-20-229. The current revision is dated 4/27/22, and you should always confirm you have the latest version from the DOR forms library before filing.
Three groups of filers use this form most often. First, registered Washington businesses that overpaid B&O tax, retail sales tax, or use tax on a prior excise tax return. Second, consumers who paid retail sales tax on a transaction that was actually exempt, such as a delivery to an out-of-state address. Third, tax preparers, CPAs, and attorneys who file on behalf of a client under a signed Confidential Tax Information Authorization (REV 42 2446) or a power of attorney.
You do not use this form for property tax refunds, unclaimed property, or refunds of motor vehicle excise tax. Those run through different agencies. You also do not use REV 41 0058 to fix a return where you underpaid tax — that requires an amended excise tax return through My DOR.
The reason the agency cares so much about who files is straightforward. Washington’s excise tax system is self-assessed, which means the taxpayer reports and pays without an audit on the front end. The refund application is the agency’s chance to verify that money really was overpaid before sending it back. Submitting the form when you are not the actual taxpayer of record will trigger a denial letter and force you to start over.
Before You Start: Documents and Information You Need
Gathering paperwork before you open the form prevents the single biggest cause of refund delays — incomplete supporting documentation. The Department of Revenue cannot process a refund without proof that tax was paid and that the payment was in error. Build your packet first, then fill out the form.
Use this pre-filing checklist. Each item exists for a specific reason, and missing any one of them slows or kills the claim:
- Your Washington UBI/Account ID number, because DOR matches every refund to the taxpayer’s registered account, and a wrong UBI routes the claim to the wrong file.
- The exact tax periods involved (month, quarter, or year), because refunds are tied to specific filed returns and the agency cannot process a vague request.
- Copies of the original excise tax returns for those periods, so DOR can compare the original reported amounts against your corrected figures.
- Amended excise tax returns if the underlying return was wrong, because the refund cannot exceed what an amended return supports.
- Invoices, receipts, or sales journals showing the exempt or overpaid transactions, since the agency requires line-level proof for each dollar claimed.
- Exemption certificates, reseller permits, or out-of-state delivery proof when the claim is based on an exemption.
- A signed Confidential Tax Information Authorization if anyone other than the taxpayer or owner is filing.
- Bank account information if you want a direct deposit refund through My DOR, because paper checks add two to four weeks of mail time.
- A clear, written explanation of why the tax was overpaid, since the “Reason for Refund” narrative is one of the most-cited reasons for denial when left vague.
- The statute of limitations date for each period, because RCW 82.32.060 bars refunds for any tax paid more than four years before the close of the current calendar year.
Janet, a bookkeeper for a Spokane construction firm, learned the hard way. She filed a refund without attaching the reseller permit copies and got a denial 90 days later. Her second submission, with the permits stapled behind the form, was approved in 6 weeks.
Where to Get the Form and How to Access It
The official PDF lives on the Department of Revenue website. Download Form REV 41 0058 directly from the DOR refund forms page or use the direct link to the Application for Refund or Credit PDF. Always pull a fresh copy each time you file, because DOR updates revision dates without much fanfare and an outdated form can be rejected.
The form is fillable in Adobe Acrobat Reader. You can type directly into the fields, save the file, and either upload it through My DOR or print it for mailing. The agency also accepts handwritten submissions in black or blue ink, but typed entries reduce data entry errors on the DOR side and speed up processing.
If you cannot download the PDF, you can call DOR’s Telephone Information Center at 360-705-6705 and request a paper form by mail. You can also pick one up at any of the DOR field offices located in Bellingham, Bellevue, Bothell, Kent, Port Angeles, Richland, Seattle, Spokane, Tacoma, Tumwater, Vancouver, Wenatchee, and Yakima.
For tax preparers handling many clients, DOR allows bulk filing through the My DOR Account Access feature. The preparer logs in under their own credentials, switches to the client’s account, and uploads the completed form as a secure message attachment. This is the fastest channel and provides an automatic timestamp that doubles as proof of filing.
Step-by-Step: How to Fill Out Form REV 41 0058 Line by Line
The form fits on a single page with three main blocks: taxpayer identification at the top, the refund detail schedule in the middle, and the certification and signature at the bottom. There is also a required Schedule of Refund/Credit attachment that breaks down the dollars by tax type and period. Walk each field in order and follow the six-element rule for every entry.
Field 1: Taxpayer Name (Legal Business Name or Individual Name)
This field asks for the exact legal name on file with the Department of Revenue. Type the name as it appears on your most recent excise tax return, including any “Inc.,” “LLC,” or “DBA” suffix. For a sole proprietor with no DBA, enter the individual’s full legal name in First Middle Last order.
A correct entry looks like Cascade Coffee Roasters LLC for an LLC, or Maria Elena Lopez for a sole proprietor. Do not abbreviate “Limited Liability Company” to “LLC” if the registered name spells it out, because DOR matches the name string against its registration database.
The most common edge case involves businesses that recently changed names. If the refund covers periods filed under the old name, enter the old name here and add a note in the Reason for Refund block explaining the change and citing the new UBI status. The agency cross-references the name to the UBI before approving the refund.
The mistake to avoid is using a trade name or website brand instead of the legal entity name. The direct consequence is an automatic mismatch flag that pauses your refund for manual review, often adding 30 to 60 days. A misconception filers carry is that DOR “knows who they are” from the UBI alone — they do not, and the name still has to match.
Field 2: UBI/Account ID Number
The Unified Business Identifier (UBI) is the 9-digit number assigned when the business registered with Washington State. Enter it without dashes or spaces. For consumers without a UBI (a private buyer seeking a sales tax refund), leave this blank and enter the Social Security Number or ITIN in the field DOR provides for individual claimants on the supplemental schedule.
A correct entry looks like 601234567. If you only have a Department of Revenue Account ID that differs from the UBI, use the Account ID printed on your most recent excise tax return.
The edge case is a closed account. If the UBI was closed because the business dissolved, you can still file a refund as long as the periods fall inside the four-year statute of limitations, but you must attach a copy of the closure confirmation letter so DOR can reactivate the account temporarily.
A common mistake is entering a federal EIN instead of the UBI, which sends the form into a manual queue. The misconception is that the EIN and UBI are interchangeable — they are not. Washington uses its own state-issued identifier separate from the IRS.
Field 3: Mailing Address
Enter the current mailing address where the refund check or correspondence should be sent. Use street number, street name, suite or unit number, city, state, and 9-digit ZIP code if available. A PO Box is acceptable if that is the address of record with DOR.
A correct entry looks like 1425 Pine Street, Suite 300, Seattle, WA 98101-2034. The agency will mail any paper check to this exact address, so accuracy matters.
The edge case is an address change. If you moved after filing the original returns, update the address with DOR through My DOR before submitting the refund form, because the address change does not retroactively apply to the refund packet.
The mistake is using a personal home address for a business refund, which causes the check to be issued to the wrong payee. The misconception is that DOR will “follow up by phone” if the address is wrong — they will not, and the check is voided after 180 days unclaimed.
Field 4: Contact Person Name and Phone Number
This is the person DOR calls if it has questions about the refund. Enter the full name, direct phone number with area code, and an email address if the form has space. The contact person should be someone who can speak to the math, the underlying transactions, and any exemption claimed.
A correct entry looks like David Park, (206) 555-0184, david.park@cascaderoasters.com. Use a real, monitored phone number, because DOR auditors call before issuing denials and an unanswered call often results in an automatic denial.
The edge case is a third-party preparer. If a CPA or attorney is the contact, attach the Confidential Tax Information Authorization so DOR can legally discuss the account with that person.
A common mistake is listing a generic “info@” email or a receptionist line that cannot answer tax questions. The consequence is a denial issued without a verification call. The misconception is that the contact person must be an officer or owner — DOR accepts any authorized representative as long as the authorization form is on file.
Field 5: Reason for Refund or Credit
This narrative box is where you explain why the tax was overpaid. Write 2 to 5 sentences, in plain English, citing the specific exemption, statute, or fact pattern. Reference the WAC or RCW that supports the claim if one applies.
A correct entry looks like Retail sales tax was collected on five invoices in Q3 2024 for goods delivered to a buyer in Oregon. Out-of-state delivery is exempt under WAC 458-20-193. Bills of lading attached as Exhibit A. That entry tells DOR exactly what happened, what law applies, and where the proof is.
The edge case is a multi-issue refund. If the claim covers two unrelated overpayments, list each issue as its own numbered item inside the box and attach a separate schedule for each. Mixing issues in one paragraph almost always triggers a request for clarification.
The mistake is writing something vague like “overpaid B&O tax” with no detail. The consequence is a 30-day deficiency letter asking for the same information you should have included up front. The misconception is that DOR auditors will read the attached invoices and figure it out — they will not, and an unclear narrative gets the file kicked back.
Field 6: Refund Amount Requested
Enter the total dollar amount you are asking DOR to refund. The number must match the sum of the line items on the attached Schedule of Refund/Credit. Use whole dollars and cents with no dollar sign — for example, 4,287.50.
A correct entry follows from your math. If the schedule lists $2,100 for B&O and $2,187.50 for sales tax, the total here is 4,287.50. The Department’s processors compare this number against the schedule total before doing anything else.
The edge case is interest. Washington pays interest on approved refunds under RCW 82.32.060, but you do not calculate it on the form — DOR adds it automatically when the refund is issued. Do not inflate the request to “include” estimated interest.
The mistake is rounding inconsistently between the schedule and the total. The consequence is a math-error notice that delays processing by 2 to 4 weeks. The misconception is that DOR will “fix small math errors” — they may, but only after the file goes to a reviewer, which adds time.
Field 7: Refund or Credit Election
The form asks whether you want a refund check (or direct deposit) or a credit applied to future tax. Check exactly one box. A credit sits on your DOR account and offsets your next excise tax return; a refund is paid out by check or ACH.
A correct entry for a business with ongoing tax liability is often the credit box, because credits post within days while refund checks take 6 to 12 weeks. A consumer with no future tax liability should always check the refund box.
The edge case is a closed business. If the UBI is closed, you cannot elect a credit because there is no future return to apply it to — choose refund. If you check credit on a closed account, DOR will convert it to a refund and mail a check, but only after extra processing time.
The mistake is checking both boxes “to keep options open.” The consequence is that the form is treated as incomplete and returned. The misconception is that you can change the election later — once the form is filed, you must submit a written request to switch, and DOR is not obligated to grant it.
Field 8: Schedule of Refund/Credit (Attachment)
This attached schedule breaks the refund into line items by tax classification, period, original amount paid, corrected amount, and difference. The columns required are: Tax Period, Tax Classification (e.g., Retailing B&O, Retail Sales Tax), Amount Originally Paid, Correct Amount, and Refund/Credit Amount.
A correct entry for a single quarter looks like a row with Q3 2024 | Retail Sales Tax | $12,500.00 | $10,312.50 | $2,187.50. Add one row per tax type per period; do not combine periods.
The edge case is interest already paid. If you paid late-payment interest on the original return that you are now amending, list the interest on its own row using the Interest classification so DOR can refund it along with the tax.
The mistake is omitting periods entirely and just stating a lump sum. The consequence is an automatic denial of the unverifiable portion. The misconception is that DOR will “pull the periods from the system” — they will not, and the schedule is the only document the processor reads.
Field 9: Signature and Date
The taxpayer, an officer of the entity, or an authorized representative signs and dates the form. Sign in ink if mailing, or use a typed signature with the date if filing electronically through My DOR. Print the signer’s name and title below the signature line.
A correct entry shows the signature, David Park, President, and the date 03/14/2026. The signature certifies under penalty of perjury that the information is true.
The edge case is a deceased taxpayer or a dissolved entity. The personal representative or former officer signs and attaches proof of authority, such as letters testamentary or articles of dissolution naming the signer.
The mistake is having a non-officer staff member sign without a power of attorney on file. The consequence is rejection on signature grounds. The misconception is that an electronic signature pasted into a PDF is always acceptable — it is acceptable only when filed through My DOR’s secure messaging, not when emailed as a loose attachment.

How to File the Completed Form
Washington offers three filing channels, and each has its own steps, processing time, and proof-of-filing requirement. Choose the channel that matches your urgency and your access to DOR’s online system.
Online through My DOR. Log in to My DOR using your SAW (SecureAccess Washington) credentials. Open the account, click Send a Message, choose Refund Request as the topic, and upload the completed REV 41 0058 PDF along with all attachments. There is no fee. Processing time runs 4 to 8 weeks for routine claims. Save the confirmation number and screenshot the submission timestamp as proof of filing.
By mail. Print the signed form and attachments, then mail the packet to Washington State Department of Revenue, Taxpayer Account Administration, PO Box 47476, Olympia, WA 98504-7476. There is no fee. Processing runs 8 to 12 weeks. Use USPS Certified Mail with Return Receipt so you have a stamped delivery date — DOR considers the postmark date the filing date for statute-of-limitations purposes.
By email or fax. DOR accepts smaller refund packets by email at DORCommunications@dor.wa.gov or by fax at 360-705-6655, but the agency strongly prefers My DOR. Email is best for claims under $1,000 with minimal attachments. Save the sent email and any auto-reply as proof of filing.
For payment of any tax owed alongside a refund of another tax type, use My DOR’s payment portal. Refund payments to the taxpayer come by paper check unless you enrolled in ACH direct deposit through My DOR, which cuts mail time by 2 to 3 weeks.
What Happens After You File
After DOR receives the form, the file moves to the Taxpayer Account Administration division for an initial completeness review, usually within 10 business days. If anything is missing, you get a deficiency letter listing the items needed and giving you 30 days to respond. Ignoring that letter results in an automatic denial.
Once the file is complete, an auditor verifies the math, the underlying returns, and any exemption claimed. For straightforward refunds — math errors, double-reported income, clear exemption certificates — approval comes in 4 to 8 weeks. For complex claims involving apportionment, nexus, or large M&E refunds, expect 12 to 24 weeks and possibly a desk audit.
If approved, DOR issues either a credit memo (posted to your account within 5 business days) or a refund check (mailed within 3 to 4 weeks of approval) plus statutory interest. Interest runs from the date the tax was paid to the date the refund is issued, calculated under RCW 82.32.060.
If denied, DOR sends a written denial letter explaining the basis. You have 30 days to file an administrative review petition with the Administrative Review and Hearings Division, or you can pay any disputed tax and sue for refund in Thurston County Superior Court under RCW 82.32.180.
Mistakes to Avoid When Filling Out the Form
These errors are the ones DOR sees most often, and each has a direct consequence that costs time, money, or both.
- Filing after the four-year statute of limitations under RCW 82.32.060, which permanently bars the refund.
- Using the trade name instead of the legal entity name, which triggers a name-mismatch hold of 30 to 60 days.
- Entering an EIN where the UBI belongs, which routes the file to a manual review queue.
- Leaving the Reason for Refund vague, which generates a deficiency letter and adds at least 30 days.
- Omitting the Schedule of Refund/Credit, which results in an outright denial because the dollars cannot be verified.
- Failing to attach amended excise tax returns when the underlying returns were wrong, which blocks approval.
- Mixing two unrelated refund issues in one form, which often causes the smaller issue to be denied for unclear documentation.
- Skipping the Confidential Tax Information Authorization when a CPA files, which prevents DOR from speaking to the preparer and stalls the case.
- Checking both the refund and credit boxes, which makes the form incomplete and bounces it back.
- Forgetting to sign and date the form, which is grounds for automatic rejection regardless of how strong the underlying claim is.
- Using a personal home address for a business refund, which causes the check to be issued to the wrong payee.
- Inflating the requested amount to include estimated interest, which triggers a math-error notice and delays processing.
Do’s and Don’ts
Do’s
- Do download the latest revision every time you file, because DOR updates the form without public notice.
- Do file through My DOR when possible, because it cuts processing time roughly in half.
- Do attach amended returns when correcting reported figures, because the refund cannot exceed what the amended return supports.
- Do calendar the four-year statute of limitations date for each period, because missing it is fatal.
- Do save proof of filing — confirmation number, certified mail receipt, or sent email — for at least four years.
- Do calculate the refund total to match the schedule exactly, because mismatches trigger math-error reviews.
Don’ts
- Don’t use Form REV 41 0058 to fix an underpayment; file an amended excise tax return through My DOR instead.
- Don’t submit photocopies of invoices that are illegible, because DOR will request originals and pause the claim.
- Don’t request a credit on a closed account, because DOR will convert it to a refund and add weeks of processing.
- Don’t write “see attached” in the Reason for Refund box; the narrative must stand alone.
- Don’t sign with a stamp signature unless you have a stamp authorization on file with DOR.
- Don’t mail the form to a DOR field office address; refund forms must go to the Olympia PO Box.
Pros and Cons of Filing on Your Own vs. With Help
Pros of filing pro se
- No professional fees, which can save $300 to $2,500 depending on the claim’s complexity.
- Direct knowledge of your own books, which often produces a more accurate Reason for Refund narrative.
- Faster initial drafting because you do not have to onboard a CPA to your records.
- Full control over the timeline and election (refund vs. credit).
- Builds internal expertise for future refund claims.
Cons of filing pro se
- Higher risk of denial for technical reasons such as missing schedules or wrong tax classifications.
- Limited ability to argue exemption or apportionment issues without tax law training.
- No buffer between you and DOR auditors during follow-up calls.
- Time cost of researching WAC 458-20-229 and related rules.
- If denied, you must learn the appeal process from scratch under tight 30-day deadlines.

FAQs
Can I file Form REV 41 0058 for taxes paid more than four years ago?
No. RCW 82.32.060 bars refunds for tax paid more than four years before the close of the current calendar year, and DOR will deny the claim regardless of the reason for overpayment.
Do I write my UBI or my federal EIN in the UBI/Account ID box?
No, federal EINs do not belong on this form. Enter the 9-digit Washington Unified Business Identifier issued at registration; an EIN entry triggers a manual review and adds weeks of processing time.
Can a CPA sign Form REV 41 0058 for me?
Yes, if a Confidential Tax Information Authorization is on file. Without that authorization, DOR will reject the signature and require the taxpayer or an officer to sign personally.
Is there a fee to file the refund application?
No. Washington does not charge a filing fee for Form REV 41 0058 through any channel, whether you submit by mail, email, fax, or the My DOR portal.
Do I check the refund box or the credit box if I plan to keep operating?
Yes, check the credit box if you have ongoing excise tax liability, because credits post within days while refund checks take 6 to 12 weeks to mail.
Can consumers without a UBI use this form for sales tax refunds?
Yes. Consumers leave the UBI blank and provide their SSN or ITIN on the supplemental schedule along with the seller’s invoice and proof of the exemption claimed.
Should I write “See attached” in Field 5 Reason for Refund?
No, the narrative must stand alone. DOR processors read Field 5 first, and a “see attached” entry usually generates a deficiency letter asking for the explanation in plain English.
Do I need to attach an amended return with the refund application?
Yes, when the underlying return reported tax incorrectly. Without an amended return, DOR cannot reconcile the original figures with your corrected numbers and the refund will not exceed what is documented.
Can I e-sign the PDF and email it to DOR?
No, electronic signatures are accepted only when the form is filed through My DOR’s secure messaging. A signed PDF emailed as a loose attachment is treated as unsigned and rejected.
Will DOR pay interest on my approved refund?
Yes. Statutory interest accrues from the date the tax was paid to the date the refund is issued under RCW 82.32.060, and DOR calculates it automatically.
Can I appeal if my refund is denied?
Yes. You have 30 days from the denial letter to petition the Administrative Review and Hearings Division or to pay the disputed tax and sue in Thurston County Superior Court.
Should I list multiple refund issues on one form or file separate forms?
Yes, you may list multiple issues on one form, but each issue needs its own row on the Schedule of Refund/Credit and its own paragraph in Field 5. Mixing issues without clear separation often causes partial denials.
