Businesses that make a large number of foreign remittances often already have the required information sitting inside their ERP, accounting software, vendor-management system or internal database.

The obvious question is: Can this data be connected directly with the Form 145 preparation process?

This is where API integration can become useful.

What Does API Integration Mean for Form 145?

An API allows two software systems to exchange information without requiring users to manually copy and paste data between them.

For example, a company's accounting system may already contain:

  • Vendor name
  • Country
  • Invoice number
  • Payment amount
  • Currency
  • Payment date
  • Nature of payment

Instead of entering these details again into a separate Form 145 workflow, an integrated system can transfer the relevant data into the preparation process.

Why Would a Business Need This?

Consider a company making hundreds of overseas payments every month.

The accounting system already has most of the transaction information. The tax team then has to review the tax treatment and prepare the required Form 145 records.

Manual data movement creates additional work and can introduce errors.

An integrated workflow can look like:

ERP / Accounting System → Form 145 Data → Tax Review → Form Generation → Filing

What About Form 146?

The same principle can be useful for organisations managing Form 146 workflows with their Chartered Accountants.

Where Form 146 is required for the applicable Form 145 Part C process, keeping the transaction data connected can reduce duplicate data entry.

The Income Tax Department currently provides a common offline utility for Form 145 and Form 146, with the forms available under the Income-tax Act, 2025.

Can 145146.com Help With Integration?

145146.com provides technology focused specifically on Form 145 and Form 146 workflows.

For businesses with existing systems, the objective is to make the transition from existing transaction data to bulk form preparation more efficient.

The technology can be combined with tax assistance so that the process is not limited to data transfer alone.

What Should You Ask Before Integrating?

Before connecting any system, discuss:

  • What data needs to be transferred?
  • Which fields are mandatory?
  • How will missing information be handled?
  • How will tax decisions be reviewed?
  • How will duplicate transactions be identified?
  • How will corrections be handled?
  • How will filing status come back into the internal system?

These questions are often more important than the API itself.

Final Takeaway

API integration can be particularly useful when Form 145 is part of a recurring, high-volume process.

Instead of treating Form 145 as a separate manual task, businesses can build it into their existing finance and tax workflow.

145146.com can support businesses looking to bring technology, bulk Form 145/Form 146 preparation and tax assistance together in one workflow.
