GSTR-1 and GSTR-3B working papers and annual return support, from reconciled books.

Input tax credit matching

Purchases reconciled with GSTR-2B, so eligible credit is claimed and gaps chased.

TDS and TCS

Deductions and collections tracked, challan data prepared and quarterly return papers organised.

Income tax working papers

ROC and MCA filings support

Statements, schedules and data for AOC-4, MGT-7 and other forms, ready for your CS or CA.

Contribution data prepared from payroll, reconciled with the books and returns coordinated.

How it works

Preparation follows the same sequence each period, so figures arrive complete and documented.

Step 1

Organise

Records are kept in order through the year, not left to pile up until the return is due.

Step 2

Prepare

GST, TDS, income tax, ROC and payroll working papers are prepared from clean, reconciled data.

Step 3

Review

Figures are checked for accuracy and tied back to the books, the GST portal and payroll.

Step 4

Support filing

Documented figures go to your chartered accountant, company secretary or local specialist for filing and sign-off.
