A GST due date reminder on WhatsApp takes one message and no setup: text NagMeLater what to remind you of and when, and it confirms within seconds and nags you at that exact time. For this topic the schedules people pick most are GSTR-1 (11th) (monthly outward supplies return, three days of buffer), GSTR-3B (20th) (the summary return and tax payment, two days early) and Send data to CA (get invoices to your accountant at the start of the month); each button above sends the exact wording, for example "Remind me on the 3rd of every month at 11am to send last month's invoices to my CA", and you can change the time or the task before sending. Recurring works in the same sentence ("every Monday at 9am"), in any language you text in. When it fires, reply done to close it, snooze 15 to be nagged again, or edit 1 to Friday 5pm to move it. First 7 days free, then $1.99 a month or $59 once for life.
GST is not a yearly scramble, it is a monthly treadmill. The 11th and the 20th come around every month whether you had a busy week or not.
Your CA files the return, but they need your invoices and data days earlier. The deadline that actually matters is the one for sending them your documents.
Miss GSTR-3B and you pay a daily late fee plus interest on the tax due. It is small enough to ignore once and expensive enough to regret over a year.
GSTR-1 (outward supplies) is due the 11th of the following month, GSTR-3B (summary plus payment) the 20th. Quarterly filers under QRMP have the 13th and the 22nd or 24th, edit the message to match.
File GSTR-1 late and your customers cannot claim their input credit on time. It is not just your fee, it is their working capital and your reputation.
Beyond the flat late fee, unpaid tax accrues 18 percent annual interest. A two-line WhatsApp reminder is the cheapest tax planning you will ever do.
The button pre-fills it. Plain words, no format to learn, no reminder app to install.
Date, time and recurrence are parsed from your message and confirmed instantly.
Right inside WhatsApp, where you will actually see it. Reply done, snooze it, or edit it any time.
Yes. Edit the message before sending: "Remind me on the 10th of January, April, July and October to file GSTR-1" or set it as "every 3 months". The bot handles both.
You can create a group and nag teammates directly: "remind @CA on the 18th to file GSTR-3B". Both of you stay in the loop.
Set a one-off: "Remind me on 15 December to start GSTR-9 preparation". Yearly recurrence works too if you want it every year.
Portal emails land in a folder you never open. WhatsApp lands in your pocket with a buzz. You already know which one you will actually see.
No download needed. NagMeLater turns WhatsApp into your GST due date reminder app: one message sets the schedule, and the nag arrives in the same chat. Nothing new on your home screen, nothing to keep updated, nothing extra to open.
The button opens WhatsApp with "Remind me on the 8th of every month at 10am to prepare GSTR-1 filing data" already typed. Send it, and it is handled.
