KDP Beginner FAQs: Straight Answers to the Questions Every First-Time Author Actually Asks

There is a strange gap between the questions KDP beginners most want answered and the places where those answers are given clearly. Amazon’s own help pages are thorough but written in policy language. Forum threads devolve into conflicting anecdotes. YouTube videos mix genuine advice with sponsored content. The result is that simple factual questions — “Do I need to register a business?” “Can I change my book after it’s published?” “What actually happens if I find a typo?” — end up feeling harder than they should.

This article is built around the questions that come up most often from authors approaching their first KDP upload. No marketing angle, no sales pitch, no “well, it depends” evasion where a clear answer exists. If you have an answer you are not sure about, one of the questions below probably covers it.

Getting Started on KDP

Do I need to register a business or incorporate before publishing? No. You can publish on KDP as an individual using your personal name or a pen name, and most beginners do exactly that. Some authors eventually set up a limited company or LLC for tax or liability reasons once their publishing income becomes significant, but this is a decision for later — not a requirement for getting started. Amazon treats you as a sole trader or self-employed author by default, and your royalties are reported to you accordingly.

Can I publish under a pen name? Yes, freely. KDP lets you enter any author name on a book, and that name does not need to match the account holder’s legal name. Many authors use pen names for genre separation (writing thrillers under one name and children’s books under another), privacy, or marketing reasons. Our guide on pen names and anonymous publishing on KDP walks through the mechanics of running multiple author identities from a single account.

Is there an age requirement? Yes — you must be 18 or over to open a KDP account. Younger authors usually publish through a parent’s account, with the parent as the contractual party and the young author as the listed author name. See the age and geographic restrictions article for the full list of eligible and ineligible countries.

Do I need to buy an ISBN? For ebooks, no — Amazon assigns an ASIN automatically and no ISBN is required. For paperbacks and hardcovers, you can either use the free ISBN Amazon provides (which marks you as “Independently Published”) or buy your own from Bowker in the US, Nielsen in the UK, or the equivalent agency in your country. Your own ISBN lets you list your chosen imprint as the publisher, which some authors care about and others do not.

How long does the whole publishing process actually take? From hitting “publish” to the book going live, expect 24 to 72 hours for an ebook and up to 72 hours for a paperback. The full timeline from finished manuscript to live book — including cover design, proofreading, file preparation, metadata, and upload — is more realistically measured in weeks, not days. The KDP publishing timeline article breaks down each stage in detail.

Money, Royalties, and Payments

How much can a beginner actually expect to earn? Honest answer: most first books earn very little in their first year. The median first-time KDP book earns somewhere between zero and a few hundred dollars over its first twelve months. A small percentage of first books break through immediately. A larger group earn modestly and build over time as the author publishes more titles. The authors making significant income from KDP almost always have ten or more books in their catalogue, not one.

When and how does Amazon pay me? Royalties are paid monthly, roughly 60 days after the end of the sales month. December’s royalties arrive in late February or early March. Payment is by direct bank transfer in most markets, with each Amazon marketplace paying in its local currency unless you consolidate via a multi-currency service. Amazon has a minimum threshold before it releases payment — typically around $100 for wire transfers or as low as $10 for direct deposit, depending on your country.

How does the 35% vs 70% royalty split actually work? For ebooks, KDP offers two royalty tiers. The 70 per cent tier is only available if your list price falls within a specific range (roughly $2.99 to $9.99 in the US, with equivalents in other markets) and the book meets other conditions like file-size limits. Outside that range you earn 35 per cent. The 70 per cent tier also deducts a “delivery fee” based on file size — a heavily illustrated book can lose meaningful royalty to this fee. Print royalties work on a different formula entirely: 60 per cent of list price minus print cost. The KDP royalties guide breaks down the maths with worked examples.

Will Amazon withhold US tax from my royalties? If you are a non-US author in a country with a tax treaty with the United States, and you complete the tax interview correctly claiming your treaty benefit, withholding drops from the default 30 per cent to 10 per cent, 5 per cent, or zero depending on the treaty. If you skip the tax interview or fail to claim treaty benefits, Amazon withholds the full 30 per cent — and that money is very difficult to recover later. The non-US authors guide walks through the tax interview questions.

Do I pay income tax on my KDP earnings? Yes. KDP royalties are taxable income in your home country regardless of how Amazon handles US withholding. You need to report the earnings to your local tax authority and pay any applicable income tax, national insurance, social security, or self-employment tax that applies in your jurisdiction. US withholding (where it still applies after treaty benefits) can typically be credited against your home-country tax bill. Consult a local accountant once your royalties become meaningful.

Rights and Exclusivity

Does Amazon own my book if I publish on KDP? No. You retain full copyright and full ownership of the work. Amazon is a distribution partner, not a publisher in the traditional sense, and the KDP agreement grants them a non-exclusive licence to sell your book — not any ownership of the content. You can unpublish at any time and take your work elsewhere. Many authors misunderstand this based on the word “publishing” in the platform name, but the legal reality is closer to a distribution arrangement than a publishing contract.

Can I publish the same book on other platforms too? For paperbacks and hardcovers, yes, always — KDP has no exclusivity on print. For ebooks, the answer depends on whether you enrol in KDP Select. If you do not enrol, you can publish your ebook on Kobo, Apple Books, Barnes & Noble, Google Play Books, and any other retailer simultaneously (“going wide”). If you do enrol in KDP Select, your ebook must be exclusive to Amazon for 90 days at a time.

What does KDP Select exclusivity actually cover? KDP Select exclusivity applies only to the digital ebook edition. Your paperback and hardcover can be sold anywhere regardless of Select status. The exclusivity also applies only to commercial distribution — you can still give away free copies as advance reader copies, email your list, or send a PDF to a reviewer. Select locks you out of competing ebook retailers, not from all other distribution. The KDP Select vs wide publishing article covers the full trade-offs.

Can I remove my book from sale later? Yes. Unpublishing is a one-click action in the KDP dashboard. Your book’s product page remains visible to people who already own it (so existing readers can still access what they bought), but new sales stop immediately. If you are enrolled in KDP Select, be aware that unpublishing does not end the Select enrolment period automatically — your book is still exclusive to Amazon for the remainder of the 90-day term even when not on sale. Auto-renewal can be turned off at any time from the KDP Select management page.

Files, Formatting, and Technical Questions

What file formats does KDP accept? For ebooks, KDP accepts .docx (Microsoft Word), .epub, and .kpf files from Kindle Create, among others. For paperback and hardcover interiors, KDP accepts print-ready PDFs. For covers, ebooks need a JPEG or PNG at specified dimensions, and print books need a wraparound PDF with bleed. The manuscript formatting requirements article covers each format in technical detail.

Can I edit my book after it has been published? Yes — and this is one of KDP’s genuine advantages. You can re-upload the interior file, update the cover, revise the book description, change categories, and edit keywords at any time. Changes to the file go through Amazon’s review process (usually 24–72 hours) before going live. The title, subtitle, and author name are the main things that cannot be easily changed post-publication; everything else is editable indefinitely.

What if I find errors in my book after it’s gone live? Fix them. Re-upload the corrected file, wait for Amazon’s review, and the updated version goes live. If the errors are significant, KDP will occasionally push the updated file to existing customers who bought the earlier version — this is done selectively and not guaranteed, but it happens. See the fix KDP formatting errors article for the exact process.

Why does my book look different in the previewer versus the final product? The previewer shows how your book will render on specific Kindle devices and apps, but the actual appearance varies by reader device, font size, and user settings. An ebook is a reflowable format, not a fixed layout — readers control how it looks. For a paperback, the previewer is closer to the final product, but minor rendering differences are normal and a physical proof copy remains essential.

Content Rules and Approval

Can my book be rejected? Yes. KDP reviews every new upload and re-upload before going live, and can reject files for technical issues (broken formatting, cover dimensions wrong, metadata errors) or content issues (suspected plagiarism, prohibited content, trademark problems). Most rejections are technical and easily fixable. The KDP file rejection reasons article lists the common causes and how to fix each.

What content is prohibited on KDP? The main categories are: content that infringes another party’s copyright or trademark, sexually explicit content involving minors, content promoting violence or hatred, misleading content designed to deceive (such as fake “companion” books that are actually just low-quality AI-generated imitations), and content that violates local laws. The full content guidelines are available in the KDP Help Centre and are worth reading before you upload anything unusual.

What if my account gets suspended? Account suspensions happen, sometimes in error and sometimes for legitimate reasons. The response is always the same: contact KDP Support through the appeal process, explain the situation clearly and professionally, and be prepared to document your legitimacy (draft files, writing history, original research for nonfiction). Getting angry at support staff is the fastest way to delay resolution. Communities like the Alliance of Independent Authors have resources specifically for navigating KDP account issues.

Sales, Reviews, and Discoverability

How do readers actually find my book on Amazon? Three main channels: keyword search (readers type what they want and your book appears), category browsing (readers explore a category and your book is listed), and recommendations (Amazon surfaces your book to readers of similar titles). All three are driven by how well you set up your metadata — keywords, categories, description — combined with early sales velocity and review signals.

Why isn’t my book selling? The most common causes are: poor cover (most common), weak book description, mismatched categories, invisible keywords, no launch plan, or simply a book that does not match current market demand in its genre. The article on why your book isn’t selling on Amazon works through each possible cause in sequence with a diagnostic approach.

How do Amazon reviews work for new authors? Anyone with an Amazon account that has spent at least $50 on Amazon in the past 12 months can leave a review on your book. You cannot pay for reviews, swap reviews with other authors, or ask friends and family to leave them — all of these violate Amazon’s terms and can get your book delisted. Legitimate paths to early reviews include an ARC team (advance readers you give the book to before launch) and organic reviews from genuine paying readers.

Do I need to run Amazon Ads? Not on day one, but yes eventually for most authors. Amazon is a crowded marketplace, and organic discovery alone rarely produces meaningful sales for a new author without an existing readership. Ads give you controllable, measurable exposure in exchange for a per-click cost. Start small, learn the fundamentals, and scale what works.

Going Global and Expanding

Does my book sell globally by default? Yes. When you publish on KDP, your book is listed on every Amazon marketplace by default — Amazon.com, .co.uk, .de, .fr, .es, .it, .nl, .co.jp, .com.au, .ca, .com.br, .com.mx, and .in. You can deselect marketplaces if you want to, but most authors leave them all enabled. Whether those marketplaces produce sales depends on whether your book matches local demand, but the listing is automatic.

Should I publish my book in other languages? Not in year one for most authors. Focus on making the English edition work first — earning reviews, refining your process, building a foundation. Translation is a significant investment that pays back best when applied to a book that has already demonstrated commercial traction. When you are ready, the multi-language publishing guide covers the decisions and costs in detail.

Can I turn my book into an audiobook? Yes. Amazon’s audiobook platform, ACX, connects you with narrators and distributes audiobooks through Audible and iTunes. You can pay a narrator upfront, split royalties 50/50 under a royalty-share deal, or record the audiobook yourself if you have the equipment and skills. Audiobook production is a meaningful project in its own right and generally comes after the ebook and print editions are established.

One Final, Underrated Question

Is KDP the right platform for my book at all? For most self-published authors, yes — it has the largest reader base, the clearest royalty structure, the best print-on-demand pipeline, and the most complete set of marketing tools. But it is not universally right. Literary authors targeting a small, high-taste audience sometimes do better with a boutique small-press deal. Academic authors may be better served by university presses or specialist publishers. Authors with strong existing direct audiences (big email lists, major platforms) sometimes earn more selling direct from their own sites with lower retailer cuts. KDP is the default for good reasons, but the default is not automatically the best choice for every book and every author.

If you are still weighing the trade-offs, the comparison in our KDP vs traditional publishing article will help clarify which route matches your goals, your book, and your timeline.

Whatever you decide, the worst version of publishing is the one that happens by default because nobody stopped to think about it. Take the time to answer the questions above honestly, and the version of your launch that results will be materially better than the one that would have happened without them.
