Business Advisory · Finance & Accounts
GST registration, GST returns and income tax filing services.
A single team runs your monthly GST returns, annual GSTR-9, TDS filings and income tax returns on one compliance calendar. Notices are handled the same way you would want if you had the time to do it yourself: read carefully, replied to properly, filed on time.
Where businesses trip
Compliance quietly compounds interest.
A missed GSTR-3B due date attracts a late fee and interest. A mismatched GSTR-2B leaves input tax credit on the table. A scrutiny notice under section 143(2) has a 6-month reply window that vanishes if the wrong person reads it first. None of these are dramatic on any single day. They add up over a financial year until the CFO or founder finds themselves negotiating with the department instead of running the business.
The fix is boring and it works. A single calendar, a single person accountable, and clean data going in at the source.

Frequently asked
GST and tax — the questions we get.
Straight answers on how GST registration and income tax filing services typically work in an engagement.
When is GST registration mandatory for a business?
GST registration is mandatory when your annual aggregate turnover exceeds ₹40 lakh (₹20 lakh for services in most states, ₹10 lakh in special-category states), when you sell across state borders, when you sell on e-commerce marketplaces, or when you are subject to reverse charge. It is also required from day one for certain categories.
What returns need to be filed under GST?
Regular taxpayers file GSTR-1 (outward supplies) and GSTR-3B (summary + tax payment) monthly or quarterly depending on turnover and QRMP election. All taxpayers file GSTR-9 annually. Composition scheme has its own returns. Cosmoura maintains a monthly compliance calendar so nothing is missed.
Do you handle income tax filing for individuals and companies?
Yes — ITR-1 to ITR-7 for individuals, HUFs, partnerships, LLPs, companies and trusts. We prepare, review, file and respond to any notices. Salaried individuals with capital gains, business income or foreign income are common.
What are TDS returns and when are they filed?
Tax Deducted at Source returns report tax deducted while making payments (salaries, contractors, rent, professional fees). Form 24Q is for salaries (quarterly), 26Q for other domestic payments (quarterly), 27Q for payments to non-residents (quarterly). Form 16 and 16A are issued annually and quarterly respectively.
What happens if I receive a GST or income tax notice?
We review the notice, prepare a factual response with supporting evidence, and file the reply through official portals within the statutory timeline. Common notices — mismatch between GSTR-3B and GSTR-2B, income tax scrutiny, TDS defaults — are recurring and mostly resolvable with a clean response.
How is Cosmoura different from a typical CA firm for GST and tax?
You get a single account lead coordinating GST + income tax + bookkeeping + payroll on one calendar. No handoffs between departments, no notices arriving because two teams did not talk to each other.
