Why get help with GST and income tax?
Looking for reliable GST & income tax consultation in Chennai? Coreinfo helps businesses, startups and individuals stay on the right side of tax rules. Tax rules in India change often. There are many returns to file, many deadlines to meet, and every mistake can lead to interest, late fees or a notice from the department. For a busy business owner, this is stressful and takes time away from running the business.
GST is the tax on the sale of goods and services. If your business is registered, you collect GST from customers, claim credit for the GST you paid on purchases, and file regular returns. Income tax is the tax on the profit or income you earn, and it applies to individuals, professionals and businesses. TDS (tax deducted at source) is tax you cut from certain payments, like salaries or rent, and deposit with the government.
We handle all three. We file on time, check your records for errors, help you plan to pay only the tax you really owe, and support you if a notice arrives.
In simple words: we keep your taxes correct, on time and stress-free, so you can focus on your business.
GST vs income tax: what is the difference?
Most businesses deal with both. Here is how they differ.
| Aspect | GST | Income tax |
|---|---|---|
| What it taxes | The sale of goods and services | The income or profit you earn |
| Who pays it finally | The end customer, through the price | The person or business that earns the income |
| How often you file | Monthly or quarterly returns, plus an annual return | Once a year, plus advance tax during the year if applicable |
| Key idea | Input tax credit: claim back GST paid on purchases | Deductions and exemptions reduce taxable income |
| Common risk | Mismatched invoices and lost input tax credit | Missed deductions, wrong advance tax and late filing |

Ask about thisGST & income tax consultation in Chennai: FAQs
How do I find a good GST consultant in Chennai?
Look for a team that handles both GST and income tax, explains things clearly, files on time and can meet you in person when needed. Coreinfo’s office is in Ramapuram, Chennai, and we support businesses across the city.
Does my business need GST registration?
It depends on your turnover, what you sell and where you sell. Some businesses must register once their turnover crosses the limit, and others, such as those selling across states or online, may need to register earlier. We will check your case and tell you clearly.
What happens if I file my GST return late?
Late filing usually means late fees and interest on any tax due. It can also delay your customers’ input tax credit, which hurts business relationships. We help you file on time and catch up on any missed returns.
What is input tax credit?
It is the GST you paid on your business purchases, which you can reduce from the GST you collect on sales. To claim it, your supplier must also file their returns correctly, which is why monthly reconciliation matters.
I received a tax notice. What should I do?
Do not ignore it, and do not panic. Read the deadline, collect the related documents and get expert help. We review the notice, prepare a clear reply and support you until it is closed.
Do you file income tax returns for salaried individuals?
Yes. We file returns for salaried individuals, professionals, business owners and companies.
Can you help us save tax legally?
Yes. We review your income and expenses and help you use the deductions and exemptions the law allows. We do not recommend shortcuts that create risk later.
How much does GST and income tax consultation in Chennai cost?
It depends on what you need: a single return, monthly GST filing, or ongoing GST, TDS and income tax support. We agree the scope and fee with you upfront, so there are no surprises.
Which documents do you need to start?
Usually your PAN, GST login details if registered, bank statements, sales and purchase records, and earlier returns. We send you a simple checklist so nothing is missed.
