How to Calculate E-Waste Tax in California
In this post, we will demonstrate how to calculate e-waste tax in California. First, we need to understand unit-based rates and their implementation. Many tax rates and tariffs are ad valorem, which means tax is calculated based on the monetary value of the goods sold or shipped. Rates can also be unit-based. Unit-based rates depend on how much of an item is sold or shipped, for example volume, mass, size, or quantity. Unit-based rates apply to many goods such as sugar, e-waste and recycling fees for electronics, lodging, and bottles. These rates have a unit of measurement and quantity. Throughout...

Nexus
VIDEO: Nexus In an earlier video, we covered how your organization’s tax profile is determined. Now, let’s explore the concept of nexus. What exactly is nexus, you may ask? Nexus is most simply defined as the areas where your organization is required to collect sales tax. To better understand this core tax concept, watch the video above. We guarantee you’ll be a nexus expert in no time!
What's My Tax Profile?
VIDEO: What’s My Tax Profile? Before using the AvaTax API, there are a few basic sales tax principles you need to understand. First and foremost is your organization’s tax profile, which is comprised of three key components: Where your organization is required to collect sales tax, a principle known as nexus The customers your organization exempts from sales tax The specific tax rates for the products and services your organization sells Watch the short video above to get a quick, basic understanding of how your organization’s tax profile is determined.
Sales Tax Got You Down? Avalara’s API Is the Answer.
Sales tax is complex and getting more complex. For example - when is a bagel taxable or tax-free? What is the threshold for taxing clothing and in what jurisdictions is it subject to tax? How do you keep up with all the changes occurring to sales tax laws? What’s the best way to handle that complexity and save your organization from expensive and damaging tax audits? Our answer? The Avalara API. The API provides comprehensive tax coverage, fast performance, strong developer support and is highly customizable. To learn more about why you should use a sales tax API, download our...
How to Validate Addresses
Calculating sales tax? Ditch the ZIPs and get rooftop-level accuracy with Avalara’s API! Valid addresses are a critical component of accurate tax calculation. I know what you’re thinking – I have the ZIP code, isn’t that enough? Not really. Why? ZIP codes are generally too broad for tax determination because zones are set at the federal level for mail delivery. State and local tax authorities often use other criteria for bounding their tax jurisdictions, such as a special stadium or restaurant tax district. So, what’s the best way to ensure your organization has up-to-date, roof-top accurate addresses? An API. The...
How to Get Tax
Boots, belts and bagels — which ones are tax-free? Here’s how to find out using Avalara’s sales tax API! You need to calculate sales tax, but it’s complicated stuff. In Indiana, marshmallows are taxed but marshmallow cream is not. In Texas, boots, belts, and hats are tax-free, but belt buckles are taxed. And in New York, bagels are tax-free, unless, of course, they are sliced. Oh, but it gets worse. Adding to the already insane complexity, the same address can be subject to multiple tax jurisdictions with different rates for different items in your shipment. Calculating sales tax accurately is...

Negative Transactions
This week I returned a doormat to Costco. I love Costco’s return policies; I was able to buy a mat to try it out, and when we discovered it wasn’t a good fit for our garage I was able to return it and buy one that was a better fit. In the world of sales, refunds are a natural thing - so how do we represent them? Defining the Two Parties In virtually all tax laws, a transaction involves exactly two parties: a buyer and a seller. However, the AvaTax API can’t just use the words “buyer” and “seller” because...

How to Handle Freight & Handling Charges
Wait, I need to include a shipping charge in my transaction? Often relegated to a single notation on an invoice, shipping and handling charges play an important role in the tax calculation of a document.

Lifecycle of a Transaction
The centerpiece of Avalara’s world-leading AvaTax service is the ‘Transaction’. A Transaction can reflect one of many different types of business documents, and it’s worth discussing how a transaction can change over time. Let’s begin by understanding how a “Sales” transaction is created, and how it can change over time. The Transaction State Diagram In AvaTax, a sales transaction is an exchange that occurs between two companies. Although other types of transactions exist that can be within a single company - for example, inventory transfer transactions - in today’s use case we will only examine transactions that occur between two...
Declaring Nexus in REST v2
One of the most frequent questions I am asked is “Where do I need to collect taxes?” The challenge of determining which jurisdictions you fall under is a complex one. In the United States, the rule that determines when your company has to obey a particular jurisdiction’s tax law is called ‘Nexus’, so AvaTax uses this word to refer to the overall concept of selecting jurisdictions where you are signed up to collect and remit taxes. Keep in mind, these rules have significant legal repercussions, and you should strongly consider getting legal or tax advice to ensure that your Nexus...

In addition to calculating tax, the AvaTax suite of products can also help you produce a robust user experience for your customers. If your customer provides a partial or mistyped address, the Address Validation API can help determine the right address based on the partial information your customer provided. For today’s blog post, I will walk you through the Address Validation functionality built into AvaTax REST v2. Validate a Partial Address We’ll begin by using the ResolveAddress endpoint to validate an incomplete address. Let’s say your salesperson was on the phone with a customer, and they took down all the...

Point-of-Sale Data API
One of the most common questions we get from our point-of-sale customers is about the need to operate in a disconnected environment, while maintaining the same level of accuracy of a connected environment. Many businesses can face periods of intermittent internet connectivity, preventing live calls to our tax engine. Some businesses wish to operate entirely disconnected. In either scenario, businesses require the means to calculate tax locally. Today, we’ll walk through a new API launching in the AvaTax 2.16.12 release - an API that generates a tax content file that can be consumed by a merchant’s point-of-sale (POS) application, supporting...
REST v2.16.12 Patch Notes
This article is about the December 2016 monthly update to the AvaTax REST v2 API. UPDATED 2016-12-07 - The team added the definition of “Mixed” sourcing to the client library to address California sourcing scenarios prior to launch. Launch has been rescheduled for Tuesday, December 13th. Environment URL Release Date Sandbox https://sandbox-rest.avatax.com 2016-12-01 Production https://rest.avatax.com 2016-12-13 POST /api/v2/transactions/create The sourcing field on TransactionLineModel had a mismatch between its documentation and its return value. In release 2.16.11, the field was documented as a string, but its value was being returned as an integer. Many libraries would still successfully parse this value...
Types of Transactions
AvaTax is a full service engine for calculating transactional taxes, including sales, use, VAT, and many other tax types. In order to properly calculate taxes in these different circumstances, AvaTax must also support a wide variety of transaction types. In today’s article, I will walk you through the differences between these transactions and describe how to map them to your business processes. Orders vs Invoices Our customers require both the ability to estimate tax for a transaction, and to record the actual tax for that transaction. Many customers use AvaTax as a way to predict taxes before taking action -...
Geocoding in REST v2
The tax on your transactions is heavily dependent on where the transactions occur. In the US sales and use tax world, transactions are generally taxed based on either the “Origin” or “Destination” - but for most retail sales, these two addresses are almost always the same. When you visit your local grocery store, they charge you a single rate based on product type and the location of the store; but if you place an order online, the tax you pay will be influenced by a number of factors including the origin location of the warehouse and the destination address where...
Estimating Tax with REST v2
The AvaTax REST API provides lots of different levels of estimated tax values, and sometimes it may be hard to know the right way to estimate tax for your customers. For today’s blog article, I will be walking you through the different types of estimates that are available in AvaTax REST v2 and how they can help you. AvaTax is of course built on correctly identifying the exact tax amounts for an invoice; and to do this, we incorporate dozens of factors including the origin and destination address, dollar amounts, taxability rules, nexus declarations, registration rules, customer exemption certificates, and...

Environment URL Release Date Sandbox https://sandbox-rest.avatax.com 2016-11-02 Production https://rest.avatax.com 2016-11-09 POST /api/v2/taxrates Corrected a bug that caused the TaxRates API to show duplicate rates.

Added new fields on the create transaction model: debugLevel (string, optional): If the user wishes to request additional debug information from this transaction, specify a level higher than 'normal'. Enum, possible values = ['Normal',...
Batched Transactions in REST v2
Uploading Batched Transactions One of the most common inquiries we get at Avalara is about the need to reconcile, or publish, a full list of a company’s transactions at the end of the month. Many businesses work by cash register day by day, and at the end of each month they produce a report listing all the transactions that they processed. Sometimes businesses will have one report for each location, or cash register, or salesperson; and they need a batch process they can use to upload all of these transactions into AvaTax for later reconciliation, or for filing tax returns....

Filtering in AvaTax REST v2
I'm sure I left this somewhere... The REST API pattern is designed to make it easy to store and retrieve data. Every piece of data in REST is assigned a single unique URL - and you can always fetch that item back by retrieving its URL. It works a bit like this: Request POST /api/v2/companies { "name": "Bob's Artisan Pottery" } Result In the result headers, you’ll get back this response that tells you the URL of your newly created object: Location: /api/v2/companies/123 Then, when it’s time to fetch something back, you can retrieve it back using that location, and...
