Collecting Tax Documentation

Suggest Edits

You can use the tax form we provide in the TaxBit SDK to collect tax documentation from your customers. We will securely store this tax information on our servers and use it to generate the necessary documents for tax compliance.

You can load the collection form using the code sample below.

Loading the tax documentation form

taxBit.ui.taxDocumentation.collect({  
  hostElement: document.querySelector("#tax-info-container")
});

This code will create an iframe and append it to the DOM element you specified in the hostElement option. The host element must be able to contain nested elements. Typically, customers use a <div></div> block as the host element. Regardless of your HTML, we recommend giving your container element an attribute ID, like <div id="taxbit-container"></div>, making it easier to customize later.

The iframe will then display a form to collect tax documentation. We host this form on a TaxBit content delivery network (CDN). The iframe will use the entire width of the <div id="taxbit-container"></div> block and will automatically resize its height to match the content inside the iframe.

If you'd like to restrain the height of the tax collection form, You can use CSS to set the height of the <div id="taxbit-container"></div> block. You will also want to enable vertical scrolling. For example, <div id="taxbit-container" style="height: 3rem; overflow-y: scroll;"></div>. Otherwise, people may only see the top part of your form. See the documentation for overflow-y for more information.

Receiving notification of critical events

The collect function will return a promise, which the system will resolve once the collection form is fully loaded. We use an object to resolve this promise, which contains another promise that we resolve once the user completes the tax documentation form successfully.

After the form is submitted successfully, a link to download the PDF file is displayed for the end user.

Receiving notification of events

const collectResult = await taxBit.ui.taxDocumentation.collect({  
  hostElement: document.querySelector("#tax-info-container")
});

// At this point, the form has been loaded in the iframe.

await collectResult.formCompletion;

// At this point, the user has successfully completed the tax documentation form.

After successfully submitting Tax Documentation

Confirmation is shown and the user is given access to the PDF of the W-9, W-8BEN, or W-8BEN-E.

Handling errors

If errors occur while the form loads or while the user completes the form, the system will reject the promise. The SDK will do its best to display a friendly error message to the user.

You should also handle these errors and provide a graceful user experience tailored to your application. For example, you could navigate the user to another part of your program.

let collectResult;

try {
  collectResult = await taxBit.ui.taxDocumentation.collect({  
    hostElement: document.querySelector("#tax-info-container")
  });
} catch (error) {
  // Handle the error that occurred while loading the form.
}

try {
  await collectResult.formCompletion;
} catch (error) {
  // Handle the error that occurred while the user was completing the form.
}

Specifying a document type

By default, the collection form will ask your customer for information to determine whether they need a W-8BEN, W-8BEN-E, or W-9 tax form. However, if you know which document the customer qualifies for, you can pass that information into the form when you create it using the documentType key. Setting documentType will prevent the form from generating tax-form-related fields.

taxBit.ui.taxDocumentation.collect({  
  hostElement: document.querySelector("#tax-info-container"),
});

Supported document types

  • W-9
  • W-8BEN
  • W-8BEN-E

If you are unsure whether the user will need a W-8BEN, W-8BEN-E, or W-9, leave the documentType blank. The SDK will ask questions to determine the appropriate document type for the account.

Providing pre-collected data

Your system likely already has some basic information about your customer, like a name and address. By providing this data to the SDK, the SDK can auto-populate related form fields or skip questions altogether, resulting in a more streamlined experience for your customer. You can use this functionality by providing a data object that includes your existing data.

taxBit.ui.taxDocumentation.collect({  
  hostElement: document.querySelector("#tax-info-container"),
  data: {
    documentType: "W-9"
    name: "Anthony Michael Pearson",
    address: {
      firstLine: "123 Lenny St.",
      secondLine: "Apt 204",
      city: "Seattle",
      stateOrProvince: "WA",
      postalCode: "98101",
      country: "US",
    },
    taxClassification: "INDIVIDUAL"
  }
});

The pieces of data you are allowed to provide depend on the value you have specified for documentType. If documentType is left blank, you may provide data in any W-8BEN, W-8BEN-E, and W-9 forms.

Note: The SDK intentionally provides leniency for provided values. For example, if you pass an invalid value of foo for taxClassification, the SDK will discard the value rather than throw an error. The collection form will then ask your customer any questions necessary to arrive at accurate and complete data. Rules for when field values will be discarded are detailed below.

Undetermined documentType

We support all fields found in the W-8BEN, W-8BEN-E, or W-9. The SDK will do its best to fill in the fields when possible, leading the user to a completed form.
