General Policies

Can I create a HIT that may contain explicit or offensive content?
If your HIT could contain explicit or offensive content, for instance, nudity, make sure to do the following:

  1. Include the following phrase in your HIT title: "(WARNING: This HIT may contain adult content. Worker discretion is advised.)"
  2. Require that Workers have the Adult Content Qualification in order to work on your HIT. This qualification requires Workers to acknowledge that they are over 18 and that they agree to work on potentially offensive content. You can set this requirement during the Design step on the Requester website or via the developer tools.
  3. Require that Workers have the Adult Content Qualification in order to preview the HIT by checking the "Required for Preview" box in the Design step on the Requester website or via the developer tools.

      Payments & Fees

      How do I pay for HITs?
      Before HITs can be published, you must fund your account. Your account funding pays the HIT reward and the Mechanical Turk fees. You can fund your account using a credit card, debit card, Amazon Payments account, or US bank account. Funds can be placed in your account at any time by clicking on "Account Settings" on the Requester website.

      Workers will be paid and Amazon Mechanical Turk fees will be charged when you approve submitted work. If you reject the work, the Worker is not paid and you are not charged the Amazon Mechanical Turk fees. Mechanical Turk Prepaid HITs are subject to Terms and Conditions.

      If you would like a refund of your Prepaid HIT purchase, please contact customer support.

      How are the fees calculated?
      Amazon Mechanical Turk collects a 10% commission on top of the reward amount you set for Workers. For example, if a HIT reward is set to $0.20, Amazon Mechanical Turk collects $0.02 for each assignment. The minimum commission charged is $0.005 per assignment. When you grant a bonus, Amazon Mechanical Turk collects 10% of the bonus amount, or a minimum of $0.005 per bonus payment.

      If you choose to send HITs exclusively to Photo Moderation or Categorization Masters an additional 20% fee applies.

      What are Mechanical Turk Masters?
      Masters are elite groups of Workers who have demonstrated accuracy on specific types of HITs on the Mechanical Turk marketplace. Workers achieve a Masters distinction by consistently completing HITs of a certain type with a high degree of accuracy across a variety of Requesters. Masters must continue to pass our statistical monitoring to remain Mechanical Turk Masters. You can have Masters who have demonstrated accuracy specifically in Data Categorization or Photo Moderation do your HITs, or you can elect to have general Masters perform your HITs. Because Masters have demonstrated accuracy, they can command a higher reward for their HITs. You should expect to pay Masters a higher reward.

      Do you support Requesters from outside of the US?
      Mechanical Turk requires that Requesters provide a U.S. billing address and a credit card, debit card, Amazon Payments account or U.S. bank account in order to publish HITs.

      Do you collect tax reporting information from non-US based Workers?
      Yes, all non-US based Workers are required to provide their name, address, and certify the following information before doing any work on Mechanical Turk.
      1) The worker is not a US citizen.
      2) The worker performs all work on HITs from a location outside of the United States.
      3) The worker does not own or lease computer servers in the United States used to do HITs.
      4) The worker will receive all payments (other than gift certificates) to a foreign address or payment instrument.
      5) The worker understands that Amazon Mechanical Turk will provide the tax information to Requesters when required to meet their U.S. Tax reporting obligations and consent to such disclosure.
      6) The worker certifies, under penalty of perjury, that the information provided is to the best of their knowledge and believes it is true, correct and complete.

      Design, Publish, and Manage HITs

      How do I create a HIT?
      The help center contains helpful guides, videos, webinars, case studies and other tools to help you get started and manage your HITs. The Mechanical Turk Requester website is ideal for business professionals who want access to the Mechanical Turk Worker community. The Requester UI Guide will explain how to design, publish, and manage your HITs on the Requester website.

      What happens when I reject work?
      When you reject an assignment, the Worker who performed the assignment does not get paid, and you are not charged the standard Mechanical Turk fee for the HIT. The rejection affects your Requester statistics and the statistics of the Worker who submitted the results.

      How do I get accurate results from Workers?
      Consult the Best Practices Guide in the Resource Center. Our Best Practices Guide helps you plan, design, and test your Amazon Mechanical Turk HITs.

      How long does Amazon Mechanical Turk keep my HITs?
      Amazon will delete HITs, HIT Types, and Qualifications if they are not used for 120 days. If you require access to HIT data for longer than 120 days, we recommend you download the HIT results and store them locally.

      Are there restrictions or prohibited uses of Amazon Mechanical Turk?
      You may not use Amazon Mechanical Turk for illegal or objectionable activities. Please refer to the policy page for examples. For example, Requesters are not allowed to collect personally identifiable information from Workers.
