Payroll Calculator API for USA

Business Challenge

The customer has the existing service, where users have access to the extensive functionality related to financial reports/documentation. This software is popular and has its target audience, which is steadily expanding. Among all, the following features are the most popular:

• Invoice generator. An invoice is a financial document that firms send to clients in order to receive payment for the provided services or goods
• 1099-MISC form generator. The 1099-MISC form is a document that includes information about any miscellaneous income except wages
• Pay stub generator. Easy creation of pay stubs using an online stub maker
• W-2 form generator. W-2 is an annual report, wages, and tax statement. Basically, this report prepares the employer for each employee

So, the W-2 form generator as a feature for simplification of wages/taxes calculation offers to use auto calculator option. Wages/tax information becomes pre-filled in the W-2 form template. Earlier, the solution for automatic payroll calculation and identifying employee wages/taxes used an external back-end. Later the client decided to implement its own payroll calculator API and to connect it to the already existing front-end. With this challenge, the customer started communication and further cooperation with the development team.

Solution

The auto calculator is a part of the existing W-2 form generator. Auto calculator makes the calculations when the user fills in the following fields:

• State
• Year
• Marital status
• Dependents amount
• The amount of earned money before taxes last year

As the first step, a business analyst researched and derived business rules for calculating taxes. Certainly, as a part of the work this engineer executed a detailed analysis of tax rules in different states of America. Of course, sometimes tax laws are the same in some states, but sometimes each state has its own unique tax rules and may differ from others. 

The main objective for the software development team is – implementation of payroll calculator API from scratch. Payroll calculator API was implemented on the Node.js stack in the AWS cloud. Notably, that client can change these business rules according to their own view of the configuration file.

Business Impact

The software development team implemented a payroll calculator API from scratch. Due to the development of this part, the customer was able to replace the external back-end solution with its code. The payroll calculator API was successfully connected to the existing front-end as a part of the auto calculator in the W-2 generator form.
