Disclaimer

PayByDate is not CBDT, GSTN or EPFO. I am not a chartered accountant firm. Nothing here is legal advice, tax advice or a filing service.

Dates move. A circular can shift GSTR-1 or GSTR-3B. Advance tax dates are well known and still you confirm the challan on the income tax portal. EPF and ESI 15th window is a typical pattern, not a holiday calendar I invent as law.

Official sites win: gst.gov.in and incometax.gov.in. Also epfindia.gov.in and esic.gov.in when the topic is salary deductions. If this calculator and the portal differ, trust the portal.

Every tool result says: this is an estimate. Confirm on the official portal. Articles are shop talk. I use first person. I skip some grammar. That is writing style, not a government notice.

Late fee caps, rebate, slabs — I use last published patterns and label them. FY 2026-27 regime compare is a labelled estimate. Your deductions, house loan, 80C, new circulars can change the number by thousands.
