Form III-B Professional Tax Annual Return Filing in Maharashtra: Due Dates & Mahagst Process

Filing Form III-B Annual Professional Tax Return in Maharashtra

Holding a PTRC registration requires more than just monthly challan payments; it demands filing the statutory Annual Return in Form III-B on the official Mahagst portal (mahagst.gov.in). The annual return reconciles total employee count, monthly salary deductions, and electronic challan identification numbers (CIN) deposited over the preceding financial year.

Under Maharashtra rules, employers whose annual PT liability is less than ₹1,00,000 file an annual return by 31st March, whereas employers with liability exceeding ₹1,00,000 must file monthly returns by the last day of each month. Late submission of Form III-B attracts an automatic late fee of ₹1,000 under Section 6(3) of the Act.
