Mistakes are skipped steps
A new business rarely chooses to break a statute. It copies a friend setup halfway. The invoice goes out on a personal UPI. The company is incorporated later. GST is added because a customer asked for a GSTIN. Annual MCA forms are postponed because revenue felt small. Each choice is understandable. Together they produce three identities and one bank feed. The cure is a review that restores the order in the and the .
A review is a decision. You are past awareness of the words “GST” and “ROC”. You need a list of what this business has already done and what it still owes. is the short course on reading the instrument itself when a summary and the portal disagree. The summary loses.
Entity and money mixed together
The first mistake is invoicing in a name the law does not recognise as the business. Founders print a private-limited suffix before , or they keep invoicing on a personal PAN after the company bank account is open. Customers do not care. The sales register does. Pick one legal person per invoice and stop the other person from issuing the next one.
The second mistake is the shared account. Business receipts, rent for a founder flat, and a supplier payment leave one UPI trail. starts by splitting that trail. Until the split exists, GST, income tax, and any company accounts are estimates. A review asks for the bank statements and marks each line as business, personal, or unknown. Unknown lines are the work.
Tax registrations assumed or borrowed
The third cluster is tax identity used without a decision. Someone registers, or does not, because a peer did. Someone else borrows a GSTIN that belongs to a cousin and uses it on a short-lived invoice. Both are failures of reading.
GST
Register when and the GST portal say you are liable or you have chosen to register. Using the GSTIN of another person on your invoice reports their supply, and it puts their credit ledger in a story they did not make. Charging GST before approval, or failing to charge it after approval, should be listed invoice by invoice in the review. The fix is a corrected commercial path, not a quieter version of the same invoice.
TDS and income tax
Paying a contractor or a professional the gross amount, without checking whether deduction applies, leaves a deposit and a return undone. Suffering TDS and then recording only the net receipt understates income and loses the credit. Read the payment on the Income Tax Department portal for the year. A review lists every vendor above the habit line you set and marks whether deduction was considered. The annual return then starts from books that show gross figures.
ROC treated as optional in a quiet year
The fourth mistake is a company that traded little and filed nothing. Existence is the trigger for annual Registrar work, not a revenue target. is master data, events, annual forms, and director KYC. A quiet year still needs accounts, a decision on audit from the current rule, and the forms MCA names. Confirm AOC-4, MGT-7, ADT-1, and DIR-3 KYC on mca.gov.in. The review writes the missing acknowledgements. It does not guess a late fee. The payment screen will compute any additional fee when you file.
Event mistakes sit beside the annual silence. A director who resigned on paper but still appears on the master will block a later form. Look up the cessation form when you find the resignation letter, and read the window on that form. A calendar copied from last year, with last year dates still in the cells, is itself a finding. Clear the dates and refill them from the portal.
A practical scenario
A founder in Coimbatore incorporates a private company in May, then keeps paying vendors from a personal account because the company account “is not active yet” in August. In July a customer demands a GST invoice. The founder borrows a GSTIN that belongs to a cousin and uses it on two bills. In the following financial year nobody files Registrar forms because the company “did not really start”. The cousin receives a credit mismatch. The personal return of the founder is full of receipts that belong to the company. The MCA master still shows the original directors, one of whom has left the city.
The review splits the work into three piles. Commercial: which invoices must be redone in the company name once GST is actually approved for the company, and which receipts belong in the founder personal return for the period before incorporation. GST: stop using the cousin number immediately and decide the company registration on the portal. ROC: build the missing annual and event rows and confirm every date on mca.gov.in before filing. None of the three piles is solved by promising the customer that it will look clean next quarter.
Read the instrument, not the forwarded message
Forwarded messages collapse a section, a rule, and a notification into one line, often with a rupee figure that expired. The discipline is short. Identify whether you are reading the Act, a rule, or a portal instruction. Note the date it applies. Write the fact pattern of this business beside it: vehicle, state, supplies, and whether a company number exists. practises that separation. A compliance review that cannot name the instrument it relied on is only another forwarded message with better formatting.
When the review is done, the business should hold a single calendar. MCA dates cite mca.gov.in. GST dates cite the GST portal. Income-tax dates cite the income-tax portal. Owners are named. The borrowed GSTIN is gone. The personal account is no longer the sales ledger. That is a decision you can operate next month, which is the only result that matters.
Checklist for a compliance review
1. List every name that has appeared on an invoice and match each to a PAN and, if used, a GSTIN that belongs to that name. 2. Separate bank lines into business, personal, and unknown. 3. Decide GST from the portal for the legal person that will trade from now. 4. List vendor payments and mark whether TDS was considered under the current income-tax rule. 5. If a company or LLP exists, compare the MCA master with the people who still hold office. 6. List missing annual acknowledgements and confirm the form and date on mca.gov.in. 7. Delete inherited due dates and replace them with dates you have just read. 8. Write the bridge from the cleaned books to the next GST period, the next income-tax return, and any Registrar form the board must approve.
Frequently asked questions
Is using a relative GSTIN acceptable for the first invoice?
No. A GSTIN belongs to the person who holds it. Decide registration for your own entity on the GST portal and invoice only after approval.
We had no revenue. Can we ignore ROC for that year?
A company still exists. Prepare the year accounts and file what MCA requires. Confirm the forms and dates on mca.gov.in. Nil is a figure, not an exemption you assume.
What penalty should we budget for late ROC forms?
Do not budget from this article. The portal computes any additional fee at payment. Read any adjudication notice you actually receive.
How far back should a review look?
From the first invoice and the first day the entity existed, whichever is earlier. Unknown bank lines and borrowed tax numbers are the priority rows.
Can the personal return and the company return share one set of sales?
Each sale belongs to the person who made it. Split the register on the date the company started invoicing. Do not report the same receipt twice.
Where do we read the law when blogs disagree?
On the GST portal, the income-tax portal, or mca.gov.in, and in the Act or rule those pages point to. A course on reading a statute is the method. The portal is the date source.
