Maharashtra Professional Tax, PTRC - Only one person working in that location - what is the procedures to pay?

Dear Team, Our branch in Maharashtra, Pune location from Dec'18 onwards, but we registered the Professional Tax under Maharashtra State Professional Tax act on Mar'20. Only one person working in that location. I want to pay the due of PT from Dec'18 to till date and what is the procedures to pay.

Dear Satheeshanandan74,
You need to apply and obtain:
1. PTEC in the name of company if your company is other than proprietary;
2. PTEC in the name of all Directors / Partners / Designation Partners of the company if they do not have it; and
3. PTRC in the name of company by giving the employee details.
After obtaining the above, you need to make payments:
1. towards PTEC in the name of company Rs. 2500 annually
2. towards PTEC in the name of all Directors / Partners / Designation Partners Rs. 2500 per annum per person. If they are already having PTEC in their name and paying towards PTEC, there is no need to pay it again. and
3. towards PTRC the tax deducted from the salary of employees.
If your tax liability is below 50K in previous year, then you need to remit the Tax annually. Else monthly. In the first year the payment is generally annually and the same is written in the certificate issued.
Whenever, you make remittance, immediately in same month you need to submit return.
All this things are online thr portal https://www.mahagst.gov.in/en

Dear Satheesh A,
Sorry, I am not able to help you out on this practical / technical difficulty.
This portal, what I know, has lot of problems technically. You are not approachable to this department online or through telephone. If you visit the office, then also you may not get any solution but you will find many souls demanding money from you for nothing. Jai Maharashtra.
