Nobody sets up a publishing account hoping to spend an evening on tax forms. You want to upload your book, pick a cover, and watch the first sale come in. Then KDP asks you to complete a tax interview, and the mood changes fast.
I’ve seen authors put this off for weeks because it looks intimidating. Others rush through it, guess at a few answers, and only find out later that a chunk of their royalties is being held back. Neither ends well. The truth is that the KDP tax interview is a short, fairly logical process once someone explains what each screen is really asking. This guide does exactly that, using the W-8BEN as the example most non US authors will run into.
One quick note before we start. I’m not a tax professional, and this isn’t tax advice. It’s a plain language walkthrough. Rules differ by country, and you should check with a qualified accountant if your situation is complicated.
Why the Tax Interview Exists
Amazon is a US company, and KDP royalties from US sales count as US source income. So the US tax system wants to know who’s being paid and where they live for tax purposes.
If you’re a US person, you’ll end up with a W-9. If you’re an individual outside the US, you’ll get a W-8BEN. If you’re publishing through a company rather than as yourself, the entity version applies, the W-8BEN-E.
The stakes are real. Without a completed and accepted form, KDP withholds tax on US royalties at the default rate, which for many non US authors is 30 percent. Royalties for ebook sales on Amazon.com, and print sales on a few other marketplaces like Amazon.ca, are affected. A properly filed W-8BEN can lower that rate if your country has a tax treaty with the United States, sometimes all the way to zero on royalties. That gap is why the interview matters.
Before You Sit Down
Ten minutes of preparation saves a lot of backtracking. Gather a few things first.
You’ll need your legal name exactly as it appears on official documents. Your permanent address in the country where you live for tax purposes. A mailing address if it differs. Your date of birth. And a tax identification number.
That last item worries people most, so here’s the reassuring part. KDP accepts either a US tax number or the tax number issued by your own country’s tax authority. Many authors don’t need to chase an ITIN, which is a hassle to get. Have your local tax number ready, and be careful copying it. A typo is one of the most common reasons forms get bounced.
Step-by-Step Walkthrough
Step One: Find the Tax Interview
Log in to your KDP account and look for the section called Tax Information, usually reachable from your account settings. If you haven’t completed it yet, you’ll see a prompt to start the interview.
Take a moment before clicking anything. Close the other tabs. Set aside twenty minutes without interruptions. The interview saves your answers as you go, but rushing is how mistakes creep in.
Step Two: Tell KDP Who You Are
The first screens ask whether you’re publishing as an individual or a business, and whether you’re a US person for tax purposes.
Be honest, and think about it properly. A US person means a US citizen, a US resident, or a US organization. If you’re living in another country and aren’t a US citizen or resident, you’re a non US person. Choose the individual option if you’re publishing under your own name.
Your answers steer the form you’ll end up with. Get this part wrong and you’ll end up with the wrong document altogether, which is a pain to unwind.
Step Three: Enter Your Personal Details
Now come the basics. Your name, country of citizenship, and permanent residence address. The permanent address is the place you live and pay taxes, not a PO box, not a hotel, and not a mail forwarding address.
If you use a separate mailing address, add it in the field provided. Otherwise you can usually leave it matching your home address.
Take care with spelling and formatting. Amazon’s system compares this information against your account, and small mismatches can delay approval.
Step Four: Add Your Tax Number
This is where you enter your taxpayer identification number. If you’re not a US person, that’s typically your foreign TIN, the number your own tax authority uses to identify you.
Different countries call it different things. It might be a national tax number, a personal identification number, or a similar reference. If you’re unsure which one counts, check your country’s tax authority website or ask your accountant before submitting. Entering the wrong kind of number is a classic slip.
You’ll also see a spot for date of birth. Fill it in the format the form requests.
Step Five: Claim Your Treaty Benefits
This screen is the reason many people avoid the interview, and it’s actually the most valuable one.
The form asks whether you want to claim benefits under an income tax treaty between your country and the United States. If your country has one, say yes. You’ll then confirm your country of residence, select the treaty article that covers royalties, and choose the withholding rate that applies.
For royalties from books, the income type is royalties, not dividends or interest, since the treaty articles differ. Treaty rates vary by country, so don’t assume a rate you heard from someone in another country. The IRS publishes treaty tables, and KDP’s help pages explain how to find your rate. Some countries lower the rate to zero, some to a modest percentage, and some have no treaty at all.
If no treaty applies to you, the default rate stays in place. Nothing you enter here will change that, and you shouldn’t claim benefits you’re not eligible for.
Step Six: Review the Form Carefully
After you answer the questions, KDP generates the form and shows it to you before you accept. Please don’t scroll past this.
Read it line by line. Check your name, address, country, tax number, and the treaty claim. If anything is wrong, don’t accept it. Go back and retake the interview so the form is corrected. Authors have found errors at this stage that would have caused problems for years.
The form is signed electronically under penalty of perjury, which just means it needs to be accurate. Don’t guess.
Step Seven: Sign and Submit
Once everything checks out, you’ll be asked to confirm that the information is correct and to sign electronically by typing your name. After that, submit.
It can take a little time for KDP to validate what you sent. In some cases Amazon may ask for more information, so keep an eye on your email, including your spam folder.
Step Eight: Check That It Worked
Don’t assume. Go back to the Tax Information section afterward and look at the tax document. You should be able to see the details of your submitted form, including the treaty rate for royalties if you claimed one.
If the rate looks wrong, or the status shows something unexpected, contact KDP support and explain what you see. It’s much easier to fix a problem now than after several months of royalties have been withheld.
Mistakes That Cost Authors Money
A few problems come up again and again.
Not finishing the interview at all is the biggest. Royalties may still be earned, but payments can be delayed until your tax information is in order.
Entering the wrong tax number is next. Digits get transposed, or people use a number that isn’t the right type.
Skipping the treaty claim happens more often than you’d think. The screen looks confusing, so people click through it, and the full withholding rate stays in place.
Then there’s forgetting to renew. Tax forms don’t last forever. KDP will notify you when yours is due to expire, so keep your contact email current and act on the reminders.
And finally, choosing the wrong form type, like picking a business form when you’re publishing as an individual. That usually means starting over.
When Your Situation Isn’t Simple
Some authors publish through a company, use a business tax number, live in one country while being citizens of another, or have income from several platforms. In those cases, the interview can get more complicated, and the safest move is to talk to a tax professional who understands cross border issues.
Also remember that the KDP interview only deals with US tax. What you owe in your own country is a separate matter, and you’ll usually need to report your royalties there. Keep good records of your earnings and payments.
Setting Up Everything Else Around It
The tax interview is only one part of getting started. If you’re still figuring out how to publish a Kindle ebook, you’ll also handle formatting, cover design, categories, pricing, and your book description.
Some authors prefer to hand those pieces to ebook publishing services so they can focus on writing. The Author Central, for example, supports authors from editing and formatting through publishing. If you need help with the manuscript itself, ebook writing services can cover that side too. When you’re comparing options, treat the search for the best ebook publishing company as a test of honesty. Ask what’s included, and be cautious about any top ebook publishing company that skips over the details of taxes, rights, or payments. Those parts are always yours to complete, and a good provider will say so.
The Short Version
Prepare your details, start the interview from the Tax Information section, tell KDP who you are, enter your personal information and tax number, claim treaty benefits if they apply, review the form carefully, sign, and then confirm the result afterward.
Do that once, do it carefully, and you can forget about it until renewal time. Your royalties stay intact, your payments come through on schedule, and you can get back to what you actually enjoy, which is writing.
