Running a part-time business alongside a full-time job or studies is a great way to build additional income and financial independence. Whether you're freelancing, selling handmade crafts, offering consulting services, or managing an e-commerce store, staying compliant with Indian tax laws—especially GST (Goods and Services Tax) and TDS (Tax Deducted at Source)—is essential.
⚠️ Disclaimer: This article is for informational purposes only. Please consult a qualified Chartered Accountant (CA) for specific legal and tax advice.
A part-time business is any income-generating activity that you manage alongside your primary job or education. Common examples include:
Selling products on marketplaces (Amazon, Flipkart, etc.)
Freelance services like writing, designing, coding
Online coaching or consulting
Dropshipping or print-on-demand businesses
Blogging and affiliate marketing
Offering digital products or services
You might think, "It's just a side hustle." But if you're earning income from it, the government sees it as a business—and that means taxes and legal compliance.
Before thinking about GST or TDS, determine how you want to structure your business legally.
Most common and easiest to start
No formal registration needed
Uses your personal PAN
You’re personally liable for profits and losses
Suitable if you have a co-founder
LLP provides limited liability
Requires a formal agreement and registration
Requires a separate PAN
A more complex structure
Separate legal identity
Needs incorporation, board of directors, filings
Ideal for scaling or attracting investors
💡 For a small or part-time business, a sole proprietorship is the easiest route.
GST is a comprehensive indirect tax levied on the supply of goods and services. It has replaced various other taxes like VAT, service tax, excise duty, etc.
You are required to register for GST if any of the following apply:
Your annual turnover exceeds ₹20 lakhs (₹10 lakhs for NE and hill states)
You supply goods or services across states
You sell through e-commerce platforms
You are a freelancer or service provider receiving foreign income (export of services)
You want to claim input tax credit
📝 You can also opt for voluntary GST registration even if you're below the threshold, to claim input tax credit and gain credibility.
To register for GST, follow these general steps:
Prepare your documents:
PAN card
Aadhaar card
Photograph
Address proof for business place
Bank account details
Business registration (if applicable)
Submit application on the GST portal
Receive your GSTIN (GST Identification Number) once your application is verified
🕒 It usually takes 3–7 working days for approval.
Every taxable supply of goods or services must have a GST-compliant invoice. Each invoice should include:
Your name, address, and GSTIN
Invoice number and date
Customer details
Description of goods/services
HSN or SAC codes
Tax rate and amount (CGST, SGST, IGST)
💡 Use billing software to ensure accuracy and compliance.
Once registered, you're legally obligated to file monthly or quarterly GST returns.
Common returns include:
GSTR-1 – Details of outward supplies (sales)
GSTR-3B – Summary return for taxes paid
GSTR-9 – Annual return (mandatory in some cases)
📅 Due Dates:
GSTR-1: 11th of the following month
GSTR-3B: 20th of the following month
🛑 Even if you have zero sales, you must file nil returns on time to avoid penalties.
One key benefit of GST registration is the ability to claim ITC—tax paid on purchases or expenses used for your business.
📌 Example:
Output tax on sales: ₹10,000
Input tax on expenses: ₹4,000
Net GST payable: ₹6,000
Only businesses registered under GST can claim this benefit.
TDS is a system where the payer deducts a portion of the payment (tax) and deposits it with the government. It applies to certain types of payments like:
Professional fees
Contractor payments
Rent
Commissions
Payments through e-commerce platforms
Even if you’re running a part-time business, TDS may apply either:
When someone pays you
Or when you pay someone else
If you’re a freelancer or service provider, clients may deduct TDS before paying you. Common deductions:
Section 194J: For professional services – 10%
Section 194C: For contracts – 1% or 2%
Section 194O: For e-commerce sellers – 1%
📥 Example:
Client pays you ₹50,000
Deducts 10% (₹5,000) as TDS
You receive ₹45,000
You can claim ₹5,000 as TDS credit when filing your income tax return
🧾 Check Form 26AS or AIS (Annual Information Statement) to track TDS deducted by others.
If your business turnover exceeds ₹1 crore (or ₹50 lakh for professionals), you may be required to deduct TDS on certain payments you make.
TDS must be deducted if you pay:
Freelancers
Contractors
Rent above a certain limit
Professionals like designers, accountants, etc.
To deduct TDS, you need to obtain a TAN.
Once you have a TAN:
Deduct TDS at applicable rates
Deposit it to the government using Challan 281
File quarterly TDS returns (Form 26Q, etc.)
Issue Form 16A to the payee as proof of deduction
💡 This may not apply to very small part-time businesses, but it’s good to know for future scalability.
To operate professionally, even a part-time business should formalize these basic aspects:
If you’re a sole proprietor, your personal PAN is sufficient
For other structures (LLP, Pvt Ltd), a separate PAN is required
Open a current bank account in your business name:
Professional image
Easier for accounting and audit
Mandatory for payment gateways and marketplaces
📑 Documents Needed:
PAN
Aadhaar
GST certificate (if available)
Address proof
Business registration (if applicable)
Registering as a Micro, Small, or Medium Enterprise (MSME) offers:
Easier access to loans
Interest subsidies
Participation in government tenders
Tax and compliance benefits
💡 It’s free and helps even small businesses build credibility.
All income earned from your side business must be declared when filing income tax.
Income from your business is treated as “Profits and Gains from Business or Profession” and is added to your total income.
You can:
Maintain detailed books of accounts and file using ITR-3
OR opt for presumptive taxation using ITR-4
This is ideal for freelancers, consultants, or small service providers.
Under Section 44ADA:
You declare 50% of gross receipts as your profit
No need to maintain books of accounts
Turnover must be below ₹50 lakhs
📥 Example:
You earn ₹20 lakhs from freelancing
Declare ₹10 lakhs (50%) as profit
Tax is calculated on ₹10 lakhs
Even for a small business, keeping accurate records helps in filing taxes and avoiding penalties.
Sales invoices
Purchase bills
Bank statements
GST returns
TDS certificates (Form 16A)
Income and expense logs
💡 Tools like Excel, Google Sheets, or accounting software (Tally, Zoho Books) can help.
📌 Ignoring GST or TDS compliance can be expensive:
Late GST filing: ₹50 per day (₹20/day for nil returns)
Late TDS filing: ₹200/day plus interest
Incorrect GST claims: Penalties + prosecution in severe cases
Non-filing of income tax: ₹5,000 to ₹10,000 penalty
✅ Even if your business is not yet profitable, file your returns on time.
🔹 Keep business and personal finances separate
🔹 Set calendar reminders for GST, TDS, and IT filings
🔹 Use digital tools to automate invoicing and record-keeping
🔹 Hire a CA for quarterly or annual guidance
🔹 Stay updated with tax changes applicable to small businesses
🔹 File nil returns when there's no income
Running a part-time business can be exciting and financially rewarding, but legal compliance is crucial for long-term success. Understanding and managing GST and TDS responsibilities ensures your business runs smoothly without legal hurdles.
Even if you're just starting out, treating your side business like a real business helps you grow professionally, build credibility, and potentially scale it into a full-time venture.
So take the necessary steps—register, file, and maintain your records—and you’ll be well on your way to becoming a legally compliant entrepreneur.
