The answer is simple: put your legal name on Line 1 of the W-9 form and your DBA on Line 2. The IRS requires this exact setup because <a href=”https://www.irs.gov/pub/irs-pdf/fw9.pdf”>Line 1 must match your tax return</a> while Line 2 shows the alternative business name you use. When these don’t match correctly, the IRS flags your W-9 as rejected, and your client faces <a href=”https://www.irs.gov/pub/irs-pdf/p1281.pdf”>backup withholding that removes 24% from all future payments</a> until fixed. Over 30% of small business owners fill out this section wrong, creating IRS notices and payment delays that could cost thousands in penalties.

What Is a W-9 Form and Why Does Your Business Need One
The W-9 form is your tax identity document. When a client or customer plans to pay you more than $600 in a year, they need this form to report that payment to the IRS on a 1099-NEC form. Think of it as a bridge between you and the IRS—your client gives the IRS proof they paid you, and the IRS matches it to your tax return.
Without a W-9 on file, your client cannot legally pay you. They must either ask you for one before sending money or they are required to hold back 24% of your payment (this is called backup withholding). This means if you earned $1,000, your client would only send you $760 and hold $240 to send to the IRS. You cannot get this money back until you file your taxes or provide a corrected W-9.
The form collects four key pieces of information: your name, your business name (if different), your tax classification type, and your taxpayer identification number (your SSN or EIN). Each piece must match exactly what the IRS expects to see in their computer system. A single typo, wrong number, or misplaced name creates a mismatch that causes rejection.
Understanding DBAs (Doing Business As): Your Business Nickname
A DBA is a legal business nickname. It is the name you use to market your business or operate under without formally incorporating. You can have one legal name and multiple DBA names, but they all connect back to your SSN or EIN. The IRS does not issue a separate tax ID for a DBA—it stays tied to your personal or business tax number.
Here’s the critical point: <a href=”https://www.wolterskluwer.com/en/expert-insights/doing-business-under-an-assumed-name”>a corporation, LLC, partnership, or sole proprietor that does business under an assumed name must comply with state DBA registration rules</a>. This means you likely filed paperwork with your county or state to register your DBA. You may have paid fees ($10 to $150 depending on your state) and potentially published a public notice. However, registering your DBA does not change how the IRS treats your tax ID.
When you fill out your W-9, you’re telling clients: “My tax ID is in my legal name, but I also do business under this DBA.” This is legal and proper. It tells the client to make the check or payment to the DBA name while reporting it under your personal or business tax number. The line between your legal identity and your business brand matters on this form.
Line 1: Your Legal Name (The Foundation Everything Rests On)
Line 1 is where your legal identity goes—not your DBA, not a nickname, not an abbreviation. <a href=”https://www.irs.gov/pub/irs-pdf/fw9.pdf”>For a sole proprietor or disregarded entity, enter the owner’s name on line 1, and enter the business/disregarded entity’s name on line 2</a>. This name must match exactly how it appears on your most recent tax return (your Form 1040 if you’re a sole proprietor).
Why does this matter? The IRS uses Line 1 as the anchor point. They compare the name you put here to their database of tax returns they received from you. If you file taxes as “Sarah Johnson” but put “S. Johnson” or “Sarah J.” on the W-9, the IRS computer flags this as a mismatch. Your client then receives a notice called a CP2100, which forces them to take action to correct your information.
If you changed your name and updated it with the Social Security Administration but have not filed a new tax return yet, you need to provide your old legal name (as it appears on your most recent tax return) on Line 1. Once you file your next tax return with your new name, you can use that on future W-9s.
Single-member LLC owners must put their personal name on Line 1, not the LLC name. This applies even though you are operating as an LLC for liability protection. Since the IRS taxes single-member LLCs as disregarded entities (meaning they ignore the LLC and tax you as a sole proprietor), your personal name goes on Line 1. Your LLC name goes on Line 2.
Do not use commas, abbreviations, or punctuation that does not exist on your actual tax return. The IRS system is sensitive to exact matches. If your name appears as “John Smith-Jones” on your tax return, use “John Smith-Jones” on the W-9. If you use “John Smith Jones” or “John Smith-jones” (lowercase), it creates a mismatch.
Line 2: Where Your DBA Belongs (And Why This Line Matters)
Line 2 is built for your DBA. <a href=”https://createaustin.org/wp-content/uploads/2024/03/Guide-to-Filling-Out-a-W-9.pdf”>If you have a business name, trade name, Doing Business As (DBA) name, or disregarded entity name that is different than the name entered on Line 1, write it in this box</a>. This line says to the client: “I operate under this other name, so you might see checks made out to this business name.”
When your client issues a 1099 form, they report payment to the name on Line 1 and reference Line 2 in their records. This tells the IRS that you operate under multiple names but have one tax ID. The IRS accepts this because it is standard business practice.
If you do not have a DBA, you leave Line 2 completely blank. Do not put anything there. Some business owners feel tempted to repeat their name or put the word “None,” but this creates confusion for whoever processes your form. Blank means you operate under your legal name only.
You can list multiple DBAs on Line 2 if you operate under more than one name. Separate them with semicolons to make it clear they are different names: “Jane’s Consulting; J Consulting Group; TechWorks”. Some clients and the IRS prefer only one DBA per form, so if you use many names, you might need to submit different W-9s to different clients showing only the relevant DBA each one pays. This prevents confusion about who is being paid.
For single-member LLCs, put your LLC name on Line 2. It is a disregarded entity name, which means it functions like an alternative name from the tax perspective. The LLC provides business liability protection but does not change how the IRS taxes you. Your personal name stays on Line 1, and your LLC name goes on Line 2.
The name on Line 2 becomes the payment name. Clients will often make checks out to whatever name appears in your Line 2 box. If you put “Sarah Johnson Consulting” on Line 2, payments will come addressed to “Sarah Johnson Consulting.” Make sure this is a name that matches your business license or DBA registration so you can deposit checks under that name.
Line 3a: Federal Tax Classification (Matching Your Structure to Your Tax Method)
Line 3a is where you tell the IRS which box describes how you are taxed. Seven options appear on the form: Individual/sole proprietor, C Corporation, S Corporation, Partnership, LLC, Trust/Estate, and Other. You check one box only. This is separate from your business structure—it is about your tax structure.
If you are a sole proprietor with a DBA, you check “Individual/sole proprietor or single-member LLC.” This is true even if you have formed an LLC that is disregarded for tax purposes. The name of your business structure does not determine this answer; the way the IRS taxes you does.
If you are a single-member LLC that is disregarded, you also check “Individual/sole proprietor or single-member LLC.” <a href=”https://www.legalzoom.com/articles/how-to-fill-out-a-w9-for-an-llc-disregarded-entity”>For a disregarded LLC, always select “Individual/sole proprietor or single-member LLC.” The wrong entity classification election can lead to incorrect tax treatment and confusion</a>.
If you own a multi-member LLC (more than one owner), you check the “LLC” box and write “P” to the right (for Partnership, since multi-member LLCs default to partnership taxation). If your multi-member LLC elected S-Corporation taxation, you write “S” to the right. If you elected C-Corporation taxation, you write “C” to the right. This tells the client and IRS which tax filing your LLC uses.
This section confuses many business owners because they mix structure with taxation. Your LLC structure protects your personal assets from lawsuits. Your tax classification determines which tax forms you file. A single-member LLC uses the LLC structure for protection but gets taxed as a sole proprietor (disregarded). You check “Individual/sole proprietor,” not “LLC,” because your tax method is sole proprietor taxation.
The TIN Section: SSN Versus EIN (The Numbers That Connect Everything)
Your Taxpayer Identification Number (TIN) is either your Social Security Number (SSN) or your Employer Identification Number (EIN). The IRS uses this number to match the name you provide to their tax return records. If your name and TIN do not match, backup withholding happens automatically.
For sole proprietors with a DBA, <a href=”https://multi-business-solutions.com/filling-out-the-w-9/”>if you put your name on line 1, you must enter your social security number here, even if you have an EIN for your sole proprietorship</a>. Your SSN is tied to your personal name, and that is what matches the IRS database. If you have an EIN for your sole proprietorship, you can use either the SSN or EIN, but SSN is preferred because it is less likely to cause confusion.
Single-member LLCs that are disregarded use the owner’s SSN or EIN, not the LLC’s EIN. <a href=”https://www.irs.gov/businesses/small-businesses-self-employed/single-member-limited-liability-companies”>For federal income tax purposes, a single-member LLC classified as a disregarded entity generally must use the owner’s social security number (SSN) or employer identification number (EIN) for all information returns and reporting related to income tax</a>. This is a common mistake—many people put the LLC’s EIN on the W-9 and then wonder why they receive CP2100 notices from the IRS.
If you do not yet have an EIN but have applied for one, you can write “applied for” in this section. Once you receive your actual EIN, you must submit an updated W-9 to all clients. EINs take only a few minutes to obtain online through the <a href=”https://www.irs.gov”>IRS.gov</a> website.
The number you provide must be in the correct format. An SSN is nine digits separated into three groups: 123-45-6789. An EIN is also nine digits but formatted differently: 12-3456789. Write them exactly as they appear on your IRS letter. If you write a number with incorrect dashes or a missing digit, the client’s system rejects it automatically.
| Your Business Type | Which TIN to Use |
|---|---|
| Sole proprietor (your legal name on Line 1) | Your SSN or personal EIN |
| Single-member LLC disregarded (your name on Line 1, LLC name on Line 2) | Your SSN or personal EIN, not the LLC’s EIN |
| Multi-member LLC, partnership, or corporation (business name on Line 1) | The business EIN |
Scenario 1: Sole Proprietor with DBA
Meet Marcus. He works as an independent consultant under the name “Marcus’s Tech Solutions.” His legal name is Marcus Rodriguez. He registered his DBA with his county and pays taxes as a sole proprietor using his Social Security Number.
When Marcus fills out his W-9, he enters:
- Line 1: Marcus Rodriguez
- Line 2: Marcus’s Tech Solutions
- Line 3a: Individual/sole proprietor (checked)
- TIN: 123-45-6789 (his Social Security Number)
Why does he put his legal name on Line 1? Because that is the name on his tax return. The IRS expects to see “Marcus Rodriguez” when they look him up. His DBA is the nickname he uses for marketing and billing, but his taxes go under Marcus Rodriguez.
When Marcus’s client receives the W-9, they see his legal name and his DBA. They make checks out to “Marcus’s Tech Solutions” (his DBA) and report payment under Marcus Rodriguez’s Social Security Number. This works perfectly because the IRS will match the name on the 1099-NEC (Marcus Rodriguez) to Marcus’s personal tax return.
If Marcus had put “Marcus’s Tech Solutions” on Line 1, his client’s system would try to match “Marcus’s Tech Solutions” to Social Security Number 123-45-6789. The IRS computer would reject this immediately because it has no record of “Marcus’s Tech Solutions” filing a tax return under that SSN. The IRS would send a CP2100 notice, and Marcus’s client would start backup withholding.
| Marcus’s Setup | What Happens |
|---|---|
| Legal name on Line 1, DBA on Line 2, correct SSN | Client issues 1099-NEC to Marcus Rodriguez; IRS matches to his tax return; payment flows normally |
| DBA on Line 1 instead of legal name | IRS rejects the name/TIN match; client receives CP2100 notice; 24% backup withholding begins; Marcus’s pay gets reduced |
Scenario 2: Single-Member LLC Disregarded Entity with DBA
Meet Claire. She formed a single-member LLC called “Claire’s Wellness LLC” but also operates under the DBA “Wellness Coaching Pro.” She is the only owner of her LLC, and she has not elected to be taxed as a corporation. This makes her LLC a “disregarded entity” for tax purposes—the IRS ignores the LLC and taxes her like a sole proprietor.
Claire fills out her W-9:
- Line 1: Claire Martinez (her legal name, not the LLC name)
- Line 2: Claire’s Wellness LLC or Wellness Coaching Pro
- Line 3a: Individual/sole proprietor (checked, not LLC)
- TIN: 456-78-9012 (her Social Security Number)
Claire makes a mistake that many LLC owners make. She thinks: “I formed an LLC, so I should check the LLC box on Line 3a.” But this is wrong. The question is not “Do you have an LLC?” The question is “How does the IRS tax you?” For a single-member disregarded LLC, the IRS taxes you as a sole proprietor. You check “Individual/sole proprietor.”
If Claire had checked “LLC” instead of “Individual/sole proprietor,” her client would think she is a multi-member LLC or an LLC taxed as a corporation. This confusion could delay payment processing or cause the 1099 to be issued incorrectly. Claire’s tax return is filed on Schedule C (sole proprietor form), not on Form 1120 (corporation form), so checking the wrong box creates a mismatch.
On Line 2, Claire can list her LLC name, her DBA, or both. Since she operates under both names, she could put “Claire’s Wellness LLC; Wellness Coaching Pro” to be clear. Different clients might pay her under different names, so listing both prevents confusion. However, she must always put her personal name (Claire Martinez) on Line 1.
The critical mistake: Claire cannot put her LLC’s EIN on the W-9. Even though her LLC has its own EIN, for income tax purposes, she uses her SSN. The LLC’s EIN is reserved for employment taxes if she has employees or for certain business obligations. For 1099 reporting, the IRS wants her SSN matched to her legal name because that is where her income gets reported on her personal tax return.
| Claire’s Correct Setup | Claire’s Common Mistake |
|---|---|
| Legal name on Line 1, LLC name on Line 2, checked “Individual/sole proprietor,” provided SSN | Put LLC name on Line 1, checked “LLC” box, provided LLC’s EIN |
| Client issues 1099 to Claire Martinez; IRS matches to her tax return; income correctly reported | Client’s system rejects name/TIN match; backup withholding starts; Claire’s pay gets held |
Scenario 3: Multiple DBAs with One EIN
Meet James. He owns a marketing agency called “James Smith Marketing LLC.” He also operates under the DBA names “Brand Builders” and “Digital Growth Strategies.” All three names connect to the same LLC and the same EIN. Different clients might pay him under different names depending on which service they use.
James’s W-9 shows:
- Line 1: James Smith Marketing LLC (his LLC name)
- Line 2: Brand Builders; Digital Growth Strategies
- Line 3a: LLC (checked, with “P” written to indicate partnership taxation—he has one other business partner)
- TIN: 78-9012345 (his LLC’s EIN)
James lists both DBAs on Line 2 with a semicolon separating them. This tells clients and the IRS that his LLC operates under multiple brand names but has one tax ID. Payment can come under any of these names, but the 1099 will always report to his LLC’s EIN.
If James had only listed “Brand Builders” on Line 2, a client paying him under “Digital Growth Strategies” might create confusion. They could wonder if this is a different entity or owner. By listing both DBAs, James prevents clients from having to request updated W-9s for each brand name he uses.
One critical rule: James cannot have a separate EIN for each DBA. The IRS issues one EIN per business entity. All DBAs connect back to that single EIN. If James wanted separate EINs, he would need to form separate businesses (separate LLCs or corporations). Since everything operates under one LLC, one EIN serves all his business names.
James could also submit different W-9s to different clients showing only the relevant DBA each one uses. For example, he might give Brand Builders clients a W-9 showing “Brand Builders” on Line 2, while Digital Growth Strategies clients see “Digital Growth Strategies.” Both would show the same LLC name and EIN on Line 1. This can reduce confusion if clients prefer to work with only one brand name per relationship.
Common Mistakes That Trigger IRS Rejection and Backup Withholding
Mistake 1: Putting Your DBA on Line 1 Instead of Line 2
This is the most common error. When you put your DBA on Line 1, the IRS tries to match “Sarah’s Consulting” to your Social Security Number. The IRS has no record of “Sarah’s Consulting” filing a tax return—they have a record of Sarah Johnson filing under that SSN. The name and TIN do not match. Your client receives a CP2100 notice, and backup withholding begins immediately.
Mistake 2: Using the Wrong TIN for Your Business Type
Sole proprietors sometimes put their business EIN on the W-9 when they should use their SSN. Single-member LLC owners frequently put their LLC’s EIN when they should put their personal SSN (since the LLC is disregarded). When the name and TIN do not match, the IRS flags it. Your client must notify you, and backup withholding starts until you provide a corrected W-9.
Mistake 3: Leaving Line 2 Blank When You Have a DBA
If you operate under a DBA and leave Line 2 blank, your client has no record that you use this alternative name. When they receive payment under a DBA name, they cannot match it to the W-9 on file. This confusion can delay payment processing or cause the 1099 to be issued under the wrong name.
Mistake 4: Changing Your Name Without Updating Line 1
If you legally changed your name or legally married and changed your last name, you need to update your W-9. Line 1 must match your current tax return. If your most recent tax return shows your married name but your W-9 shows your maiden name (or vice versa), it is a mismatch. Update your W-9 with all clients once you have filed a tax return under your new name.
Mistake 5: Using Abbreviations or Punctuation That Does Not Match Your Tax Return
If your tax return shows “Sarah Johnson-Smith” but you put “Sarah Johnson Smith” (no dash) on the W-9, this is a mismatch. The IRS computer looks for exact matches. Similarly, if you abbreviate “Robert” as “Bob,” it does not match your tax return. Use the exact legal name as it appears on your tax return, character for character.
Mistake 6: Checking the Wrong Tax Classification Box
Many single-member LLC owners check “LLC” when they should check “Individual/sole proprietor.” Single-member LLCs are disregarded entities taxed like sole proprietors. Checking the wrong box tells the client and IRS that you are taxed differently than you actually are. This can cause issues when the client reports your income on the wrong type of 1099 form.
Mistake 7: Providing an Incorrect SSN or EIN
A typo in your TIN causes immediate rejection. If you put 123-45-6780 instead of 123-45-6789, the name and TIN do not match. Triple-check your TIN before submitting the W-9. Match it exactly to what appears on your IRS letter or Social Security card.
Mistake 8: Not Updating the W-9 When Your Business Structure Changes
If you started as a sole proprietor, got an EIN, and now have employees, you need a new W-9. If you converted your sole proprietorship to an LLC, you need a new W-9. Outdated information causes the IRS to flag your record. Update your W-9 whenever your business structure, tax classification, or legal name changes.
Mistake 9: Signing the Form Digitally or Not Signing at All
Many business owners think digital signatures work on the W-9. They do not always. Some clients require an actual handwritten signature under penalties of perjury. Without a valid signature, the W-9 is incomplete. Your client may refuse to accept it and may start backup withholding as required by law until you provide a properly signed form.
Mistake 10: Failing to Match Your DBA Exactly to Your State Registration
You registered your DBA with your state and it has a specific legal name. When you put this name on Line 2 of the W-9, use the exact name as registered. If you registered “Sarah’s Wellness & Consulting, LLC” but you write “Sarah’s Wellness and Consulting” on the W-9, it creates confusion. Use the exact registered name so clients can verify it matches your state records.
Do’s and Don’ts: Actionable Rules That Prevent Rejection
Do put your legal name on Line 1 — Use the exact name as it appears on your income tax return. No abbreviations, no nicknames, no variations. This is the anchor that the IRS uses to verify your identity.
Don’t put your DBA on Line 1 — Your DBA goes on Line 2, not Line 1. Putting it on Line 1 creates an immediate name/TIN mismatch that triggers backup withholding at 24%.
Do update your W-9 whenever your legal name changes — If you legally married, divorced, or changed your name, file an updated W-9 with all clients once your next tax return is filed under the new name.
Don’t leave Line 2 blank if you operate under a DBA — Clients need to know you use an alternative name. Blank Line 2 creates confusion when payments come under your DBA name.
Do use your exact SSN or EIN as shown on your IRS letter — Match the format and dashes exactly. No typos, no variations. One wrong digit causes rejection.
Don’t use the LLC’s EIN on a single-member disregarded LLC’s W-9 — Single-member LLCs must use the owner’s SSN or personal EIN for income tax reporting, not the LLC’s business EIN.
Do check the tax classification box that matches how the IRS taxes you, not your business structure — Single-member LLCs are disregarded and taxed as sole proprietors, so check “Individual/sole proprietor,” not “LLC.”
Don’t abbreviate, use nicknames, or remove punctuation from your legal name — “Bob” instead of “Robert” or “Smith” instead of “Smith-Jones” causes rejection. Match your tax return exactly.
Do get a handwritten signature on the form — Digital signatures are not always accepted. Most clients require a handwritten signature under penalties of perjury in the certification section.
Don’t wait to provide a W-9 until your client asks — Provide it proactively before you start work. If your client has to ask, it delays payment processing and may trigger backup withholding on your first check.
Pros and Cons: When DBAs Help and When They Create Problems
| Situation | Pros | Cons |
|---|---|---|
| Using a DBA for a sole proprietorship | Builds brand identity without forming an LLC; allows multiple business names under one tax ID; more professional appearance | Provides no liability protection; requires state registration and potential renewal fees; clients must keep track of two names on W-9 |
| Using a DBA with a single-member LLC | Protects personal assets from liability; allows separate business name; professional branding | Creates complexity in naming requirements; requires matching LLC name to owner name on W-9; increased filing fees for LLC formation |
| Operating under multiple DBAs | Reach different markets under different brands; keep separate customer bases; one tax ID serves all | Clients may get confused about which business they are paying; requires listing multiple names on W-9; difficult to keep track for accounting purposes |
| Using an EIN as a sole proprietor (optional) | Adds privacy by not putting SSN on W-9; appears more professional to large clients; separates personal and business finances | Extra step to apply for EIN that is not required; some clients expect to see SSN; does not provide liability protection; adds accounting complexity |
| Registering a DBA versus forming an LLC | DBA registration is quick and inexpensive ($10–$150); minimal paperwork; simple to maintain | No personal asset protection; state requires renewal; may require newspaper publication; easy for someone else to register similar name |
| Listing multiple DBAs on one W-9 | Clear communication to all clients about your business names; prevents confusion when payments come under different names | Line 2 becomes crowded; some clients prefer one name per form; increases chance of data entry errors |
Frequently Asked Questions
Q: Can I put just my DBA on Line 1 instead of my legal name?
No. <a href=”https://multi-business-solutions.com/filling-out-the-w-9/”>Line 1 must show the name as it appears on your 1040 tax return. If you file as a sole proprietor using your legal name, that name goes on Line 1</a>. Putting your DBA on Line 1 creates a name/TIN mismatch that causes backup withholding.
Q: What if my DBA is registered under a different legal name than I currently use?
Register your DBA again under your current legal name, or submit a W-9 showing your current legal name on Line 1 and update your DBA registration with the state. Mismatches between your legal name and DBA registration can create processing problems. Your tax return uses your current legal name, so your W-9 must match.
Q: Do I need an EIN for my DBA?
Not always. <a href=”https://www.legalzoom.com/articles/do-i-need-an-ein-for-a-dba”>If you’re a sole proprietor or operate a single-member LLC, you can use your Social Security number instead of an EIN for tax purposes</a>. An EIN is optional unless you have employees or run a partnership or corporation.
Q: Can I list two DBAs on Line 2 of my W-9?
Yes. Separate them with a semicolon or slash to make clear they are two separate names: “Brand A; Brand B.” Some clients prefer only one DBA per form, so you may need to submit different W-9s showing different DBAs to different clients.
Q: What happens if my W-9 has the wrong name or TIN?
Your client receives a CP2100 notice from the IRS. They must send you a letter asking for corrected information. If you do not respond within 15 days, they start backup withholding at 24% on all your payments. You get less money, and it continues until you provide a corrected W-9.
Q: If I have both an SSN and an EIN as a sole proprietor, which do I put on the W-9?
Either one works if you have both. However, SSN is preferred because it creates fewer mismatches. Your personal income tax return uses your SSN, so the IRS expects to see your SSN on income-related documents like the W-9.
Q: Do I need to file a DBA with my county or state to use it on the W-9?
Yes, in most states. <a href=”https://www.doola.com/blog/dba-state-filing-fees-per-state”>Filing fees range from $10-$150, with most states charging $20-$50 for initial DBA registration</a>. Check your state’s requirements. Using an unregistered DBA might violate state law.
Q: What if I operate in multiple states under different DBAs?
Register each DBA in the state where you operate. Use the DBA you want clients to see on Line 2. You still use your personal or business name on Line 1. Each state’s registration is separate; one EIN covers all of them.
Q: Can I use a P.O. Box for my business address on the W-9?
No. <a href=”https://www.irs.gov/pub/irs-pdf/fw9.pdf”>The W-9 requires a physical street address, not a P.O. Box</a>. Use your actual business location or home address if you work from home. The IRS needs a real address to contact you.
Q: How often do I need to submit a new W-9 to my clients?
Only when something changes: your legal name, your address, your tax classification, or your DBA. If nothing changes, the original W-9 stays valid. However, many large companies ask clients to re-submit W-9s annually for their records, even if no changes happened.
Q: If my W-9 is rejected, how long does backup withholding last?
Until you provide a corrected W-9 and your client receives it. Backup withholding stops within 30 days of your client getting the corrected form. However, you still get the withheld money when you file your tax return and claim it as a payment on your return.
Q: Can I submit a W-9 electronically or does it have to be printed and signed?
Both work. Many platforms accept electronically signed W-9s using DocuSign or Adobe Sign. However, some clients and government agencies require a printed form with a handwritten signature. Ask your client which format they accept.
Q: What if I listed the wrong DBA on Line 2?
Provide an updated W-9 with the correct DBA name. Mismatched DBA names do not cause backup withholding like name/TIN mismatches do, but they create confusion in client records. It is better to correct it quickly than let the wrong name stay on file.
Q: Do I list my business’s DBA on Line 2 if I am a single-member LLC disregarded entity?
Yes. Put your personal name on Line 1 and both your LLC name and any DBA on Line 2 to be completely clear. Your client then knows you operate as an LLC under a specific brand name, all connected to one tax ID.
Q: What does the certification section require me to confirm?
You confirm under penalties of perjury that your TIN is correct, you are not subject to backup withholding, you are a U.S. citizen or lawful resident, and the information on the form is accurate. A false statement can result in a penalty of up to $250 per form. This is why accuracy matters.
