AWS Taiwan FAQs

一. Amazon Web Services（AWS）為什麼推出台灣亞馬遜網路服務有限公司？

在不久的將來，台灣亞馬遜網路服務有限公司（以下簡稱「AWS 台灣」）將取代Amazon Web Services, Inc.（以下簡稱「AWS, Inc. 」），成為所有被識別為位於台灣的AWS帳戶的合約方及AWS服務轉售商。這項變更首先影響擁有統一編號的AWS帳戶，並於2026年擴及無統一編號的客戶。

二.為什麼由 AWS 台灣取代 AWS, Inc.，成為位於台灣的AWS帳戶的轉售商？

在 AWS，能夠有效地支援我們的客戶和合作夥伴對我們來說很重要。我們定期審查我們的業務結構，以確保我們能夠為客戶提供最佳服務。Seller of Record (SoR) 是在司法管轄區內成立的當地商業實體，以轉售 AWS 雲端服務。新的 SoR成為與當地客戶的 AWS 合約方，以便客戶可以自當地企業取得發票並以當地貨幣支付款項。

三.我的哪些 AWS 帳戶受到影響？

位於台灣的 AWS 帳戶將改由 AWS 台灣提供服務。 

四.AWS 如何判斷我的帳戶是否位於台灣？

AWS 會根據帳戶的稅務設定和/或帳單和聯絡地址來判定每個帳戶的帳戶位置。

五. 轉換為AWS台灣後，我與AWS之間交易方式有什麼主要變更？

台灣客戶帳務面的主要變更包括：(i) 每期帳單將包含兩份文件— 符合稅法規定繁體中文版本的電子發票 ，以及英文版的補充發票，包括詳細的服務項目和付款指示；(ii) 所有 AWS 服務將收取5%營業稅，包括雲端服務、AWS 培訓和 AWS  專業服務，以及 AWS 合作夥伴網路 (APN) 費用；(iii) 可使用當地貨幣 (新台幣) 付款，以及 (iv) 在AWS帳單和成本管理主控台，以及洞察工具中，帳戶使用將標記為AWS台灣。AWS 服務的定價和計費方式不會有任何變化，也不會對您的工作負載或服務購買造成影響。

六.我對 AWS 服務使用方面會有什麼改變？此變動會造成服務中斷嗎？

服務不會有任何變化，您可以繼續使用目前使用的服務，而不會發生任何中斷。您的帳號、資料內容、設定、存取權限和安全設定將保持不變。

七.我需要與 AWS 台灣重新簽約嗎？

AWS 客戶合約或其他規範您使用 AWS 雲端服務的合約，將自動從AWS, Inc.轉換至AWS台灣成為您的台灣 AWS 雲端服務的合約方。若您在變更後繼續使用 AWS 雲端服務，即視為您同意與 AWS 台灣的合約，您不需要重新簽署任何現有已執行的合約。

八.當我的合約方更改為 AWS 台灣時，會有什麼變化？

• 定價將維持使用美金計價，而且服務項目將與 AWS, Inc 提供的服務相同。
• 如果您使用信用卡付款，預設將以新台幣支付。如果您是依發票付款(PBI)，則可以選擇使用新台幣或美金支付。
• AWS台灣支援的信用卡包括 AMEX、Visa、Mastercard、Diners Club International和JCB。
• 如果您是依發票付款(PBI)，則需將款項匯至AWS台灣新的當地銀行帳戶。
• 所有電信相關產品將由 AWS 台灣銷售，以下 5 項電信產品除外：

                        o    ContactCenterTelecomm
                        o    AmazonChimeVoiceConnector
                        o    AmazonChimeBusinessCalling
                        o    AmazonChimeDialInAMCS
                        o    AmazonChimeCallMeAMCS

• 對於從 AWS 台灣購買的服務，AWS 台灣將向您開立發票。對於從 AWS, Inc. (例如 AWS Marketplace) 購買的服務，客戶將繼續收到由AWS, Inc. 開立的發票。 
• 您在帳單主控台上的使用體驗大致維持不變，但您的服務使用狀況將顯示於AWS台灣法律實體下。AWS 台灣開立的發票將會上傳到主控台的帳務頁面，供您檢視。
• 如果您是 AWS 專業服務或 AWS 培訓客戶，您的發票處理方式和與您進行交易的實體將保持不變，僅匯款資訊會配合雲端服務更新。
• 如果您在台灣和其他國家/地區持有帳戶，則根據您的帳戶所屬地區，您將分別收到個別的發票。

九.我的 AWS Marketplace產品和服務會發生什麼變化？

您透過 AWS Marketplace 購買的產品和服務沒有變更。這些產品和服務將繼續由 AWS, Inc. 開立發票。您需要維護系統和流程，去支付 AWS, Inc. 所有 AWS Marketplace 消費的發票。如果同一計費期內您也同時從AWS台灣收到AWS服務使用的發票，您將需要進行兩筆支付，一筆給AWS, Inc.以支付您在Marketplace的消費，另一筆支付給 AWS 台灣。

十.客戶互動和通信相關服務（CHIME/Connect/SNS）會發生什麼變化？

所有電信產品將由 AWS 台灣銷售， 5 種電信產品除外：

                        o    ContactCenterTelecomm
                        o    AmazonChimeVoiceConnector
                        o    AmazonChimeBusinessCalling
                        o    AmazonChimeDialInAMCS
                        o    AmazonChimeCallMeAMCS

十一.我的 AWS 培訓和 AWS 專業服務會發生什麼變化？

AWS 培訓和 AWS 專業服務的帳單和付款方式將不會改變。AWS 台灣將繼續向台灣客戶銷售 AWS 培訓和 AWS 專業服務。我們已在台灣設立當地銀行帳戶，以接收 AWS 培訓和 AWS 專業服務的付款。推出AWS 台灣前，我們將通知您新的匯款指示。

十二.我的預留執行個體(Reserved Instance, RI)/儲蓄計劃(Savings Plan, SP)會怎樣？

任何預留執行個體或儲蓄計劃都將繼續適用於任何符合條件的匹配使用情況，即使購買後的 SoR 有任何變化，對於具有每月定期使用費用（無預付或部分預付計劃）的預留執行個體或儲蓄計劃，這些定期性費用將依使用量匹配及預留執行個體/儲蓄計劃所涵蓋的帳戶（如果已啟用預留執行個體/儲蓄計劃共用）由相對應 SoR 計費。如果預留執行個體或儲蓄計劃的使用未能匹配或歸屬，將由原始銷售預留執行個體/儲蓄計劃的帳戶的SoR進行計費。

例如，如果連結帳戶在德國購買預留執行個體，任何預付款都將由 AWS EMEA SARL 作為賣家計費。如果預留執行個體涵蓋德國連結帳戶的使用情況，或者預留執行個體不符合任何使用情況，AWS EMEA SARL 將向德國連結帳戶收取的定期性費用。如果預留執行個體涵蓋其他位於台灣連結帳戶的使用情況，AWS台灣將向台灣帳戶收取適用的定期性使用費。

十三.我應該預期收到哪些發票文件？

AWS 台灣將提供電子發票，該發票也將傳送到財政部（當地稅務機關）的電子發票整合平台。電子發票 將包含您和 AWS 的稅務詳細資料，並反映總銷售稅額和發票總金額。電子發票將根據台灣稅務機關的格式要求產生，並以繁體中文和新台幣金額顯示。您也會收到一份補充發票，與您現在從 AWS, Inc. 收到的商業發票相似。此文件將包含按服務收費的詳細資訊，並顯示您的總費用摘要。

根據預設，發票文件將通過電子郵件發送到付款人帳戶的電子郵件信箱（如果您已啟用交付偏好設定）、帳單地址和其他帳單地址（如有提供），您也可以透過 AWS 帳單主控台存取文件。如果帳戶中沒有有效的稅務資訊，AWS 台灣將視為B2C交易去開立一般電子發票，這些發票無法用於營業稅進項稅額扣抵。

十四.如果我與 AWS 台灣進行交易，我是否需要提供稅務資訊？

若要從 AWS 台灣接收符合營業稅扣抵規定的營業稅發票，您必須提交您的稅務資訊。您可以直接在 AWS 帳單主控台的稅務設定中更新稅務資訊。企業 (B2B) 客戶得輸入或更新其統一編號 (UBN)，且必須以繁體中文輸入公司名稱和地址，才能正確產生稅務發票。

十五.AWS 台灣接受哪些稅務登記號碼和格式？

AWS 台灣將接受八位數的統一編號 (UBN)。您可以在 AWS 管理主控台的稅務設定頁面上新增此項目至您的帳戶。如果您是 AWS 組織的付款帳戶擁有者，您可以編輯所有位於台灣或我們接受稅務登記號碼 (TRN) 的其他國家/地區的所有會員帳戶的稅務設定。如果組織中的所有帳戶都共用相同的 TRN，請考慮啟用稅務設定繼承功能。

十六.當我支付發票款項時，我會收到付款證明嗎？

AWS 台灣不會發出單獨的付款收據。付款資訊將反映在付款主控台上的帳戶的交易記錄中。 

十七.如果我在月中更新我的稅務地址，台灣營業稅是如何計算的？

AWS 會使用您提供給我們的最新帳單資訊來計算適用稅捐。一次性購買，例如預留執行個體、網域名稱或儲蓄計劃，將在購買時開立發票。您每月對其他服務的定期使用情況，將根據當時反映的稅務地址在使用後下個月的第四天左右開立發票。因此，請檢查您的稅務設定及帳戶資料正確性，以確保您的發票反映正確的資訊。

十八.發票會以什麼語言開立？ 

AWS 台灣將提供英文的補充發票。電子發票將以繁體中文開立。

十九.如果我想對發票進行更正，流程將如何進行？

如果您因姓名、金額或任何其他資訊問題而需要重新開立發票，您可以聯絡客戶支援以討論您的情況。AWS 將審核並就發票調整請求建立支援單。經您同意，我們將作廢原始發票，並重新開立載有正確稅務資訊的發票給您。惟若已逾報稅期限，我們將向稅務機關申請核准作廢原始發票並重新開立正確資訊的發票。重新開立的發票可在帳單主控台上找到。 

二十.AWS 台灣支援哪些付款貨幣和付款方式？

AWS 台灣的客戶可以選擇以美元或新台幣支付依發票付款 (PBI)。您需要透過付款偏好設定頁面設定首選貨幣，以便發票反映所選貨幣。請按照下列步驟更新您的付款幣別偏好設定。如果您沒有選擇首選貨幣，或者 AWS 台灣不支援您的首選貨幣，您將收到新台幣的補充發票，並根據以美元計算並轉換為新台幣的服務費用收費。

AWS台灣推出初期，依發票付款(PBI) 將是 AWS 台灣唯一支援的付款方式。2026 年將支援 Visa、Mastercard、AMEX、Discover、Diners Club International和JCB等信用卡。AWS 台灣不支援預付款、短付款及 ACH自動轉帳/直接扣款。 

二十一.我的服務價格會變更嗎？如何計算以台幣計算的費用？

服務價格將不會變更，並將繼續以美元計價。如果您已將首選貨幣設定為新台幣，服務費用將以美元計算，並轉換為新台幣以開立發票和付款。 

二十二.在哪裡找到發票貨幣匯率的價格？ 

AWS 發票會顯示美元金額、本地貨幣金額和轉換的匯率，此資訊位於發票第一頁的摘要區段中。客戶可以在 AWS 帳戶中找到發票。 

二十三.我可以指定發票的匯率嗎？

AWS 台灣是使用第三方金融市場匯率提供商於發票產生時匯率。AWS 不會公佈每個發票週期所選的實際匯率提供者。如需詳細資訊，請參閱 AWS 服務條款第 1.17 節。 

二十四.我根據發票條件支付 AWS 服務費用，我有什麼需要做嗎？

請遵循以下三個步驟：(1) 確保您和您的應付帳款部門準備將帳款匯入台灣的 AWS 台灣銀行帳戶；(2) 向您的應付帳款部門或銀行確保您可以將帳款匯入台灣的新銀行帳戶，並 (3)於帳單主控台上的採購單功能來更新採購單資訊（適用於使用採購單的客戶）。新的匯款指示將反映在 AWS 台灣發票中，如果您想收到有關匯款指示的銀行或 AWS正式信函，請在我們推出AWS 台灣前與您的客戶經理或 AWS 支援人員聯繫以接收信函。

二十五.AWS 台灣 SoR 推出後，我的採購單會受到什麼影響？ 

使用採購單的客戶可以選擇使用現有採購單來涵蓋 AWS 台灣購買項目，或個別開立採購單。客戶可以於帳單主控台上更新採購單資訊，以確保 採購單中的 AWS 實體包含AWS 台灣。請參閱 AWS 帳單與成本管理使用指南中的管理採購單。  

二十六.我的帳戶是 AWS 組織 (合併帳單組織) 的付款帳戶。如何檢查我的所有會員（連結）帳戶是否都有正確的地址和相關的 AWS 銷售實體？

付款帳戶擁有者可以瀏覽 AWS 帳單主控台中的「稅務設定」頁面，查看與每個帳戶相關聯的稅務地址和 AWS SoR。如果您是 AWS 組織的付款帳戶的擁有者，則可以編輯所有位於台灣的會員（連結）帳戶的稅務資訊。最右邊的「賣家」欄會指示每個帳戶的SoR (例如 AWS ,Inc.、AWS EMEA SARL 或 AWS 台灣)。如果您的組織中的所有帳戶都共用的稅務資訊，請考慮啟用稅務設定繼承，因為這將節省您的時間，並確保即使帳戶加入或離開 AWS 組織時也會套用 TRN。如果任何會員帳戶必須屬於其他司法管轄區，則不應使用「稅務繼承」功能。在可能的情況下，AWS 組織內的稅務發票將針對所有具有相同稅務資訊的帳戶合併。 

二十七.我的帳戶是 AWS 組織的付款帳戶（合併帳單組織），而我擁有位於不同國家/地區的成員（連結）帳戶，我應該預期什麼變化？

AWS 將根據帳戶位置確定每個帳戶的 AWS SoR。如果您的會員（連結）帳戶由不同的SoR提供服務，則您將從每個 SoR 收到單獨的發票。每個 SoR 將在發出的發票或付款要求上有自己的匯款指示。付款必須以發票上顯示的貨幣匯入適用的SoR。請注意，您將需要以補充發票上顯示的貨幣分別匯款給不同賣家所開立的發票或補充發票。 

二十八.我可以於AWS組織中的帳戶依SoR選擇不同預設貨幣？ 

可以，您可以通過付款設定依 SoR 設置不同預設貨幣，以便您可以依首選貨幣及付款方式自 SoR 取得發票，更多詳細資訊可以在這裡找到。 

二十九.我是 AWS 合作夥伴/解決方案提供商。AWS 台灣對我有何影響？

作為解決方案提供商，您與 AWS, Inc. 已簽署轉售經授權AWS 服務的任何協議，就您符合資格的台灣帳戶，也適用於AWS 台灣。為確保變更也會反映在您的連結帳戶上，請按照操作指南，透過啟用稅務設定繼承，將您自己的稅務設定套用至所有連結帳戶。作為 AWS 合作夥伴/解決方案提供商，您負責管理和收取最終客戶適用的稅務。

三十.AWS 台灣如何影響 AWS 合作夥伴網路 (APN) 提供的方案和優惠？ 

位於台灣的 AWS 合作夥伴將繼續按照 APN 條款和條件獲得優惠，並由 AWS台灣作為合約方。若要判斷 AWS 台灣的推出是否影響您的帳戶，請聯絡您的合作夥伴開發經理(PDM)。登入 AWS 合作夥伴中心，即可找到合作夥伴開發經理的聯絡資料。

三十一.AWS 台灣的推出會如何影響 AWS 合作夥伴資金請求？

AWS 台灣推出後將成為 AWS 合作夥伴在台灣提出所有資金請求的 AWS 合約方。AWS 合作夥伴在資金請求中輸入的匯款地址將根據下列方法決定 AWS 合作夥伴的位置和 AWS 合約方。推出後，位於台灣的 AWS 合作夥伴需要在 Amazon 收款人中心註冊，才能提交新的資金請求。AWS 台灣將開立採購單 ，AWS 合作夥伴將根據採購單詳細資訊開立發票。對於匯款地址在台灣以外的 AWS 合作夥伴，AWS 台灣將不是 AWS 合約方。 

 三十二.AWS 台灣推出後會如何影響在推出前提交但尚未獲得資金的資金請求？ 

在 AWS 台灣推出前提交的任何資金請求，都將由發出相關採購單的原始 AWS 合約方支付。  

1. What is AWS launching with Amazon Web Services Taiwan Limited?

In the near future, Amazon Web Services Taiwan Limited (“AWS Taiwan”) will replace Amazon Web Services, Inc. (AWS, Inc.) as the AWS contracting party and reseller of AWS services for all AWS accounts identified as being located in Taiwan. This change will first impact AWS accounts with a Unified Business tax identifier (UBN) on file, and extend to customers without a UBN in 2026.

2. Why is AWS Taiwan replacing AWS, Inc as the reseller of AWS services for AWS accounts located in Taiwan?

At AWS, being able to support our customers and partners effectively is important to us. We regularly review our business structures to verify that we are able to serve our customers best. A local Seller of Record (SoR) is a local business entity established within a jurisdiction to resell AWS cloud services. The new SoR becomes the AWS contracting party with local customers, so customers can be invoiced by and pay to a local business entity in local currency.

3. Which of my AWS accounts are affected?

AWS accounts determined to be located in Taiwan will be served by AWS Taiwan. 

4. How does AWS determine if my account is located in Taiwan?

AWS will determine each individual account’s account location based on the account’s Tax Settings and/or billing and contact addresses.

5. What are the key changes in how I will transact with AWS with this launch?

Primary changes to the billing experience for Taiwan customers include: (i) Two artifacts per invoice—tax-compliant electronic government uniform invoice (e-GUI) in Traditional Chinese, and supplemental invoice in English with detailed service breakdown and remittance instructions, (ii) 5% VAT collected on all AWS services including Cloud, AWS Training and AWS Professional Services, and AWS Partner Network (APN) fees, (iii) support for payment in local currency (New Taiwan Dollars), and (iv) AWS Taiwan will be tagged to the account's usage in the Billing and Cost Management Console and Insights tools. There will be no change to the pricing and metering of your AWS services, and no impact on your workloads or ability to purchase AWS services.

6. Will my access to AWS services change? Will I experience service down time?

No, there will be no change in the services, and you can continue using the same services you use today, without interruptions. Your account number, content, configurations, access rights, and security settings will remain the same.

7. Do I need to sign a new agreement with AWS Taiwan?

The AWS Customer Agreement, or other agreement governing your use of AWS cloud services, will be automatically transferred from AWS, Inc. to AWS Taiwan as your AWS cloud services reseller for your Taiwan accounts, in accordance with its terms. Your continued use of AWS cloud services after the change will constitute your acceptance of the agreement with AWS Taiwan. You do not need to re-sign any existing executed agreement(s).

8. What will change when my contracting party changes to AWS Taiwan?

• The AWS Customer Agreement, or other agreement governing your use of AWS cloud services automatically transferred from Amazon Web Services, Inc. to AWS Taiwan for your eligible Taiwan accounts. Your continued use of AWS cloud services after the change constitutes your acceptance of the agreement with AWS Taiwan. You do not need to re-sign any existing executed agreement(s).
• Pricing will remain in US dollars and service offerings will remain the same as those that are offered by AWS, Inc.
• If you pay by credit card, you will pay in Taiwanese dollars by default. If you pay by invoice, you will have the option to pay in either Taiwanese dollars or US dollars.
• AMEX, Visa, MasterCard, Diners Club International, and Japan Credit Bureau will be the supported card payment methods in AWS Taiwan.
• If you pay by invoice, you will remit your payments to the new local bank account.
• All Telecom products will be sold by AWS Taiwan, with the exception of the below 5 telecom product offerings, which will not be sold in Taiwan:

                    o    ContactCenterTelecomm
                    o    AmazonChimeVoiceConnector
                    o    AmazonChimeBusinessCalling
                    o    AmazonChimeDialInAMCS
                    o    AmazonChimeCallMeAMCS

• You will be invoiced by AWS Taiwan for purchases made from AWS Taiwan. For any purchases from AWS, Inc. (e.g., AWS Marketplace), customers will continue to get invoices from AWS, Inc. 
• Your experience on the Billing Console will generally remain the same, except that you will see AWS Taiwan as a separate legal entity, summarizing the usage tied to AWS Taiwan. Invoices generated by AWS Taiwan will be uploaded to the console in Bills Page for you to view.
• If you are an AWS Professional Services or AWS Training customer, your invoicing experience and the entity you transact with will remain unchanged. Your remittance information will change to match that of cloud services.
• If you have accounts based in Taiwan and other countries, you will receive separate invoices depending on the country associated with your accounts.

9. What happens to my AWS Marketplace products and services?

There are no changes to the products and services you purchase through the AWS Marketplace. These products and services will continue to be invoiced by AWS, Inc. You will need to maintain your systems and processes to pay invoices from AWS, Inc. for all AWS Marketplace purchases. If you also receive an invoice from AWS Taiwan for AWS service usage for the same billing period, you will need to make two payments: one to AWS, Inc. for your Marketplace purchases and one to AWS Taiwan.

10. What happens to customer engagement and communications-related services (Chime/Connect/SNS)?

All Telecom products will be sold by AWS Taiwan, with the exception of the below 5 telecom product offerings, which will not be sold in Taiwan: 1) ContactCenterTelecomm, 2) AmazonChimeVoiceConnector, 3) AmazonChimeBusinessCalling, 4) AmazonChimeDialInAMCS, 5) AmazonChimeCallMeAMCS.

11. What happens to my AWS Training and AWS Professional Services?

The billing and payments experience for AWS Training and AWS Professional Services will not change. AWS Training and AWS Professional Services to Taiwan customers will continue to be sold by AWS Taiwan. We have set up a local bank account in Taiwan to receive your payments for AWS Training and AWS Professional Services. We will inform you of new remittance instructions as we approach the launch of AWS Taiwan.

12. What happens with my existing RIs/Savings Plans?

Any Reserved Instance (RIs) or Savings Plans (SPs) will continue to apply towards any eligible matching usage, regardless of any change in SoR since purchase. For RIs or SPs with monthly recurring usage charges (no-upfront or partial-upfront plans), these recurring charges will be billed by the SoR based on the account whose usage matches and is covered by the RI/SP (if RI/SP sharing has been enabled). If the RI or SP does not match and cover any usage, it will be billed to the SoR based on the account that originally purchased the RI/SP. 

For example, if a linked account in Germany purchases an RI, any upfront payment would be billed by AWS EMEA SARL as seller. And if usage by the German linked account is covered by the RI or if the RI does not match any usage, applicable recurring charges would be billed to the German linked account by AWS EMEA SARL. If usage by another linked account based in Taiwan is covered by the RI, applicable recurring usage charges would be billed to the Taiwan linked account by AWS Taiwan.

13. What invoicing documents should I expect?

AWS Taiwan will provide a tax e-invoice (e-GUI) that will also be transmitted to the E-Invoice Platform of the Ministry of Finance (local tax authority). The e-GUI will contain both your and AWS’s tax details and will only reflect the total tax amount and the total amount of the invoice. e-GUIs will be generated based on the formatting requirements of the Taiwan tax authority, and will be in Traditional Chinese and denominated in TWD currency. You will also receive a supplemental invoice that will be similar to the commercial invoice that you receive today from AWS, Inc. This document will contain details of the charges by service and will show the summary of your total charges.

The invoicing documents will be emailed by default to the payer account’s root email address (if delivery preference has been enabled by you), billing address and alternative billing address (where provided). The documents will also be accessible via the AWS Billing Console. If there is no valid tax information on the account, AWS Taiwan will treat it as a B2C transaction and generate tax e-invoices, which cannot be used to claim VAT input credit from the tax authority.

14. Will I be required to provide tax information if I need to transact with AWS Taiwan?

To receive tax-compliant VAT invoices from AWS Taiwan, you must submit your Tax information. Tax information can be updated directly in the Tax Settings of the AWS Billing Console. Business (B2B) customers input or update their Unified Business Number (UBN). Legal name and address must be entered in Traditional Chinese to enable proper tax invoice generation.

15. What Tax Registration Numbers and formats does AWS Taiwan accept?

AWS Taiwan will accept an eight-digit Tax registration number, also known as Unified Business Number (UBN) in Taiwan. This can be added to your accounts on the Tax Settings page in the AWS Management Console. If you are the owner of a Payer account for an AWS Organization, you can edit the Tax Settings for all member (linked) accounts based in Taiwan or any other country where we accept a Tax Registration Number (TRN). If all accounts in your Organization share the same TRN, please consider enabling Tax Settings Inheritance.

16. Will I receive an invoicing artifact when I make a payment(s) for an invoice?

AWS Taiwan does not issue a separate payment receipt/invoice. The payment information will be reflected in your account's transaction history on the Payments Console. 

17. If I update my tax address mid-month, how is Taiwanese VAT calculated?

AWS uses the latest billing information you have provided us to calculate applicable taxes at the time an invoice is generated. One-time purchases like Reserved Instances, Domain Names, or Savings Plans will be invoiced at the time of purchase. Your regular monthly usage of other services will be invoiced around the fourth day of the month following usage based on your tax address reflected at that point. Therefore, please check your Tax Settings to make sure that your account information is correct to ensure that your tax invoices reflect the correct details.

18. What language will invoices be issued in? 

AWS Taiwan will provide the supplemental invoice in English. The tax invoice (e-GUI) will be in Traditional Chinese.

19. If I would like to make corrections to an invoice, what will the process look like?

If you need a tax invoice re-issued due to issues with the name, amount, or any other details, you can contact Customer Support to discuss your case. AWS will review the case and open a support ticket for the invoice adjustment request. Upon receiving your consent, we will cancel the original tax invoice and re-issue a new invoice to you with the correct details. However, if it exceeds the tax filing period, we will need to submit a separate application to tax authority for permission to cancel the original tax invoice. The re-billed invoice will be available on the Billing Console. 

20. What payment currencies and payment methods are supported by AWS Taiwan?

Customers in AWS Taiwan can choose to pay either in US dollars or New Taiwan Dollars for Pay By Invoice (PBI). You will need to set your preferred currency via the payment preferences page in order for the invoice to reflect the chosen currency. Please update your Payment Currency Preference by following these steps. If you do not select a preferred currency or if your preferred currency is not supported in AWS Taiwan, you will receive a supplemental invoice in TWD, with a line item breakdown based on service charges computed in USD and converted to TWD.

At initial launch PBI will be the only payment method supported in AWS Taiwan. Credit cards including Visa, Mastercard, AMEX, Discover, Diners Club International, and Japan Credit Bureau will be supported in 2026. Advanced Pay (prepayment), shortfall payment and ACH/Direct debit are not supported in AWS Taiwan.  

21. Will the pricing of my services change? How will the charges in TWD be calculated?

Service pricing will not change and will continue to be published in USD. Service charges will be computed in USD and converted to TWD for invoicing and payment if you have set your preferred currency as TWD. 

22. Where is the price to invoice currency FX rate found? 

AWS invoices display the USD amount, the local currency amount, and the foreign exchange rate used for the conversion. This information is in the invoice summary section on the first page of the invoice. Customers can find their invoices in their AWS accounts. 

23. Can I request AWS to customize my invoice’s FX rate calculation? 

AWS Taiwan uses the exchange rate from a third-party financial market rate provider determined at the time the invoice is generated. The actual rate provider selected by AWS for each invoice cycle is not published. Please refer to AWS Service Terms, Section 1.17, for more details. 

24. I pay for my AWS services on invoicing terms. Is there anything I need to do?

Please follow the following three steps: (1) ensure you and your Accounts Payable (AP) department are prepared to remit payment to the AWS Taiwan bank account located in Taiwan, (2) check with your AP department or your bank to ensure you can remit payment to the new bank account in Taiwan, and (3) access the purchase orders (PO) feature on Billing Console to update PO information (for customers who use POs). The new remittance instructions will be reflected in the AWS Taiwan invoice. If you would like to receive an official bank letter or AWS letter regarding the remittance instruction, please reach out to your Account Manager or AWS Support to receive the letter as we approach the launch of AWS Taiwan.

25. How will my purchase orders (POs) be affected after the AWS Taiwan SoR launch? 

Customers who use purchase orders have the option to leverage the existing PO to cover the AWS Taiwan purchases or issue a separate PO. Customers can access the purchase orders feature on Billing Console to update the PO information to ensure AWS Taiwan is included as an AWS entity to the PO. Refer to managing your purchase orders in the AWS Billing and Cost Management User Guide.  

26. My account is the Payer account for an AWS Organization (consolidated billing family). How do I check that all my member (linked) accounts have the correct address and associated AWS seller entity?

Payer account owners can see the Tax Address and AWS SoR associated with each account by visiting the Tax Settings page in the AWS Billing Dashboard. If you are the owner of a Payer account for an AWS Organization, you can edit the tax information for all member (linked) accounts based in Taiwan. The far-right column ‘Seller’ will indicate each account’s SoR (e.g., AWS Inc., AWS EMEA SARL, or AWS Taiwan). If all accounts in your Organization share the same tax information, please consider enabling Tax Settings Inheritance as this will save you time and ensure the TRN is applied even when accounts join or leave your AWS Organization. If any member accounts must belong to a different jurisdiction, the Tax Inheritance feature should NOT be used. Tax invoices within an AWS Organization will be consolidated, where possible, for all accounts with the same tax information. 

27. My account is the Payer account for an AWS Organization (consolidated billing family) and I have member (linked) accounts based in different countries, what should I expect?

AWS will determine the AWS SoR for each individual account based on the account location. If you have member (linked) accounts being served by different SoR(s), you will receive separate invoices from each of the SoRs. Each SoR will have its own remittance instructions on the invoice or request for payment it issues. Payment must be remitted in the currency displayed on the invoice to the applicable SoR. Please note that you will be required to remit payment separately for invoices or supplemental invoice from different sellers in the currency displayed on the applicable supplemental invoice. 

28. Can I choose my preferred currency by SoR for my accounts in the AWS Organization? 

Yes, you can setup your preferred currency by SoR via payment profiles so that you can get your invoices by SoR in your preferred currency and preferred payment method. More details can be found here. 

29. I am an AWS Partner/Solution Provider. How does AWS Taiwan impact me?

As a Solution Provider, any agreement(s) governing your resale of authorized AWS services you have signed with AWS, Inc. will also be applicable to AWS Taiwan for your eligible Taiwan accounts. To ensure the changes are also reflected on your linked accounts, please follow the operational guidance to apply your own Tax Settings to all of your linked accounts by enabling Tax Settings Inheritance. As an AWS Partner/Solution Provider, you are responsible for managing and charging your end customers’ applicable taxes.
  
30. How does AWS Taiwan affect programs and benefits provided by the AWS Partner Network (APN)? 

AWS Partners located in Taiwan will continue to receive benefits following the APN terms and conditions with AWS Taiwan being the applicable AWS contracting party. To determine if the AWS Taiwan launch impacts your accounts, contact your Partner Development Manager (PDM). You can find your PDM’s contact details by logging in to AWS Partner Central.

31. How does the AWS Taiwan launch impact an AWS Partner funding request?

After launch, AWS Taiwan will be the AWS contracting party for all funding requests made by AWS Partners located in Taiwan. The remittance address entered by the AWS Partner on the funding request will determine the AWS Partner’s location and the AWS contracting party based on the following method. After launch, AWS Partners located in Taiwan will need to register at Amazon Payee Central before they can submit a new funding request. AWS Taiwan will raise the purchase order (PO) and AWS Partners will submit their invoice according to the PO details. For AWS Partners with a remittance address outside Taiwan, AWS Taiwan will not be the AWS contracting party. 

32. How does the AWS Taiwan launch affect funding requests submitted before launch but have not been funded yet? 

Any funding request submitted before AWS Taiwan launch will be paid by the original AWS contracting party that issued the associated purchase order (PO).
