Common Mistakes in GST Registration and How to Avoid Them
Since the Goods and Services Tax (GST) was first introduced in India, any business that can make more than a certain amount of money or sells things across state lines needs to sign up for GST. The signup process is simpler these days than before, yet plenty of folks—particularly SMEs—still see their submissions stalled or turned down due to preventable errors.

and legit. It fosters trust, allows input tax credits on buys, and streamlines dealings with clients and vendors. Even minor slips in docs or forms can lead to suspension, revocation, or outright denial.
In this article, we'll go over some of the most common mistakes people make when registering for GST and give you easy tips to avoid them. This will help make your GST sign-up process go as smoothly as possible.
Picking the Wrong Taxpayer Category
One of the first things you need to decide when registering is what kind of taxpayer you are – Regular, Composition, Casual Taxable Person, Non-Resident Taxable Person, E-commerce Operator, etc.
Common mistake:
A lot of businesses just pick Regular taxpayers without really knowing if it's the right choice for them. Small businesses that don't make much money might be better off under the composition scheme, but they end up paying more taxes and filing returns more often than they need to.
How to avoid it:
Think about the size and type of your business before you pick a category. For example:
The composition scheme is often good for small dealers who don't make a lot of money and don't sell things across state lines or through online stores.
If you're only selling things temporarily at events like exhibitions or trade shows, choose Casual Taxable Person.
Typing in the Wrong Legal and Trade Names
Your legal name has to be exactly the same as the name in the government's PAN database. Even small differences like typos, abbreviations, or different punctuation can cause problems and get your application rejected.
How to avoid it:
- Make sure your legal name matches the PAN database perfectly.
- Your trade name—the actual name you use for your brand or business—can differ from the legal one.
- Review your spelling and punctuation carefully before submitting the application.
Uploading Business Proof That Isn't Valid
When listing your business address, you'll need to upload proof—such as a utility bill, lease agreement, property deed, or authorization letter.
Common mistake:
People sometimes upload documents that are old or don't really prove anything:
- Rent agreements that have expired
- Utility bills that are more than 2 months old
- Missing permission letters when you're sharing or renting a space without a formal agreement
How to avoid it:
PAN and Aadhaar Details Don't Match
Aadhaar verification is now required for most GST registrations, so if the details on your PAN and Aadhaar cards don't match, it can slow things down.
How to avoid it:
Check that the name, birthday, and gender on your PAN and Aadhaar cards are the same.
If they're not, update either your Aadhaar or PAN information before you apply.
Picking the Wrong HSN / SAC Code
HSN codes are for goods, and SAC codes are for services. People often just pick codes randomly without checking what category their business actually falls into.
Why this is risky:
- Picking the wrong code can lead to you paying the wrong amount of tax.
- It also makes you more likely to get a tax notice or have your ITC rejected.
How to avoid it:
- Look up the right HSN/SAC code for your business on the GST portal or in government guides.
- If you sell lots of different products or services, list all the codes that apply.
Entering the Wrong Bank Account Details
A lot of people type in the wrong bank account numbers or upload statements from accounts that aren't active.
How to avoid it:
Use your current business account (not your personal savings account, unless you're a sole proprietor).
Upload clear copies of your bank statement, passbook, or a canceled check that shows your business name and account number.
Picking the Wrong “Place of Business” Type
People often get confused between Principal Place of Business, Additional Place of Business, and Branch.
How to avoid it:
- Your Principal Place of Business is where you run your business and keep your documents.
- Add every location where you store things or provide services, including warehouses, branches, or storage facilities.
- If you don't add all your business locations, it can cause problems later.
Not Providing a Proper Authorization Letter
For companies, LLPs, trusts, and partnerships, an authorized person needs to sign the application. If you don't include an appointment letter or board resolution, your application will be rejected.
How to avoid it:
- Upload a board resolution or authorization letter that clearly says who is authorized to sign for GST.
- If required, make sure the digital signatures (DSC) are in the name of the authorized person.
Not Doing Your Aadhaar Authentication Quickly
After you submit your GST registration, you'll get a link to do your Aadhaar authentication. If you wait too long, they might do a physical verification, which takes longer.
How to avoid it:
Ignoring Notices About Your Application
The GST department might ask you for more information or corrections. If you ignore these notices:
If you don't provide the information they ask for by the deadline, your application will be canceled, and you'll have to start all over.
How to avoid it:
Not Understanding the Turnover Threshold for Registration
A lot of business owners think that GST registration is optional until they make more than ₹40 lakh.
But in many cases, you need to register even if you make less than that, such as:
How to avoid it:
Understand the rules for when GST registration is required. If your business falls into one of those categories, apply even if you don't make much money.
Not Getting Professional Help When You Need It
GST registration might seem simple, but people often get stuck because of technical issues, errors on the portal, or problems with their paperwork.
How to avoid it:
If you're not sure about something, get help from a professional accountant, GST consultant, or tax expert. Avoiding small mistakes early on can save you time and money later.
