Auto Deadline Reminder System on Email – For Income Tax and GST

Author: CA.Aashish Sachdev

The Problem: A Compliance Headache We All Face

Imagine this – It’s the end of the month, you’re knee-deep in work, and suddenly it hits you – the GST deadline was yesterday. Panic. Late fees. Compliance nightmares.

For Chartered Accountants, finance professionals, and industry veterans, staying on top of tax deadlines is not just a necessity; it’s a responsibility. But in an age where automation is solving complex problems, why are we still relying on manual tracking, reminders, and last-minute rushes?

We need a system that works for us—an intelligent assistant that ensures no deadline is ever missed.

The Solution: A Smart, Automated Reminder System

Here’s what we built: an Automated Tax Deadline Reminder powered by Google Apps Script, Forms, and Sheets. This system is elegant, efficient, and, most importantly, scalable.

How does it work?

Step 1: User Sign-Up – A simple Google Form captures the user's details: Name, Email, and the type of updates they want (GST or Income Tax).

 Step 2: Intelligent Deadline Tracking – A Google Sheet maintains all important tax due dates categorized by GST and Income Tax, dynamically adjusting each year.

 Step 3: Automation Takes Over – A Google Apps Script runs every midnight, scanning the due dates and matching them with today’s date.

 Step 4: Personalized Email Alerts – If a match is found, the system sends a personalized email reminder with the due date and a brief description of the filing requirement.

 Step 5: Smart Logging – Each sent email is logged in a separate Email Log Sheet, ensuring duplicate emails aren’t sent and providing an audit trail for compliance teams.

Building This Without a Tech Background – The Role of GPT and Generative AI

As a Chartered Accountant, I wasn’t a developer. But I had a vision, and AI helped bridge the gap.


Here’s how GPT and Generative AI played a crucial role in building this system!

  1. Step-by-Step Code Generation: I started with a basic prompt – “How to send automated emails using Google Apps Script?” GPT provided a starting point, and I iterated from there.
  2. Debugging and Refinement: Whenever the script had errors, GPT helped diagnose the problem and suggested fixes.
  3. Optimized Logic Design: Instead of manually figuring out the logic, I refined my queries to GPT, which suggested better ways to structure my Google Sheets and automate the workflow.
  4. Personalized Email Content Generation: GPT also helped draft professional, engaging email templates, making the reminders more effective.
  5. What started as a simple idea transformed into a fully functional automation system, all thanks to AI-assisted problem-solving.

How to Make This Scalable?

While this system works perfectly for GST and Income Tax deadlines, it can be extended to:

  1. Corporate tax filings
  2. MCA compliance & annual filings
  3. Internal finance reporting deadlines
  4. Statutory audits and ROC compliance
  5. Payroll tax and TDS return filing reminders

Future Improvements:

  1. Multi-channel notifications – Extend alerts to WhatsApp, Slack, or SMS.
  2. Dynamic user preferences – Allow users to choose multiple compliance categories.
  3. AI-driven predictive alerts – Use AI to analyse user patterns and send proactive reminders.
  4. Dashboard & analytics – Provide a live dashboard for firms to track deadlines in real-time.

The Industry Impact: Beyond Just Tax Compliance

This isn’t just about avoiding penalties. It’s about making compliance stress-free.

For CAs – Automates a recurring process, saving countless hours in follow-ups and client reminders.

For Businesses – Ensures financial discipline and avoids unnecessary fines.

For the Industry – Sets a precedent for leveraging AI-driven automation in compliance.                                                                                    

Final Thoughts: The Future of Compliance is Automated

Why should we manually track deadlines when technology can do it better? This system ensures that compliance is no longer a burden but a seamless, background process that just works.

This journey shows that even non-tech professionals can harness AI and automation to solve real-world problems. With the right tools and iterative learning, anyone can build something impactful.
