When You Need a W-9

The general rule

Anyone who's going to pay you money that the IRS needs to know about will ask you for a W-9. The W-9 lets them collect your Taxpayer ID so they can later report the payment correctly on a 1099 (or other information return).

If you're an individual paying another individual for personal reasons (paying a friend back for dinner, gifting cash to a family member), no W-9 is involved. The W-9 only enters the picture when there's a business or financial reporting context.

Most common: starting a freelance or contract gig

This is the W-9 use case most people encounter. When a business hires you as an independent contractor, freelancer, or vendor, and they expect to pay you $600 or more during the year, they're required by IRS rules to collect your W-9 before issuing payment.

Examples:

• You're a graphic designer hired for a logo project
• You're a writer working on contract for a publication
• You're a web developer building a site for a client
• You're a consultant providing services to a company
• You're a photographer covering a wedding for a couple's business
• You're an Etsy seller, Uber driver, or DoorDash delivery contractor (these platforms have their own W-9 collection process)

If you provide services as an independent contractor, expect a W-9 request from any client paying you over $600/year.

Banks and brokerages

Financial institutions need your W-9 to report interest, dividends, and other investment income to the IRS. You'll typically encounter this when:

• Opening a new bank account that earns interest
• Opening a brokerage account
• Setting up an IRA or 401(k) rollover
• Receiving stock dividends

Most banks build the W-9 information into their account opening process, you may not even realize you've technically completed a W-9 because they ask the same questions through their own forms.

Real estate transactions

Real estate is a major W-9 use case:

• Selling your home, the closing agent collects a W-9 from the seller to report the transaction on Form 1099-S
• Receiving rental income, if a property management company pays you rent on behalf of tenants, they need your W-9
• Mortgage interest, your lender may need a W-9 if you're receiving mortgage interest income (rare, mostly for hard-money lenders)
• Real estate commissions, agents and brokers regularly fill out W-9s for the brokerage they work under

Other situations that trigger W-9

• Royalties, book authors, songwriters, mineral rights holders
• Prize money, game shows, sweepstakes, gambling winnings, esports tournaments over $600
• Awards and grants, academic prizes, research grants from foundations
• Settlement payments, legal settlements (some, not all, depending on type)
• Affiliate marketing earnings, Amazon Associates, ShareASale, CJ Affiliate, etc.
• Influencer / sponsored content payments, paid brand partnerships, including barter arrangements valued over $600
• Speaker fees and honoraria, universities, conferences, corporate events
• Board member compensation, for-profit and non-profit boards

When you do NOT need a W-9

• You're a W-2 employee. Employees fill out W-4s, not W-9s.
• Personal payments. Paying friends back, gifting money, splitting rent, no W-9 needed.
• Payments under $600/year from a single payer. Technically you might still be asked for one, but the legal requirement triggers at $600.
• You're a corporation receiving payments. C-corps and S-corps are generally exempt from 1099 reporting (with exceptions for legal/medical services). Some clients still collect W-9s anyway.
• You're a foreign person or entity. You'd use a W-8 form instead. See our W-8 guide.

How often do you need to provide a new W-9?

Generally, once per client. The W-9 stays on file until your information changes (new address, new business name, new TIN). If something changes, send the client a fresh W-9 right away, especially if you've moved or changed your business structure (e.g., went from sole prop to LLC).

Some larger companies require an annual W-9 update as part of their vendor compliance process. That's not an IRS requirement, it's just the company's internal policy.
