Advance Tax for Professionals and Business Owners: Who Pays, When, and How Much

Most salaried employees never worry about advance tax — their employer handles it through TDS deductions. But if you are a freelancer, consultant, doctor, architect, business owner, or receive substantial income from interest, rent, capital gains, or side gigs — advance tax is your responsibility.

Who Must Pay Advance Tax?

Under Section 208 of the Income Tax Act, advance tax is mandatory if your tax liability for the year (after all deductions) exceeds ₹10,000.

Liable: Freelancers, self-employed professionals, business owners, partners in firms, HUFs, companies (different schedule), salaried employees with additional income (rental income, capital gains, interest income, etc.)

Not liable: Senior citizens (60+) who do not have business income (they pay self-assessment tax at year-end)

The Quarterly Installment Schedule

Advance tax is paid in four installments during the financial year:

For presumptive taxation (44AD/44ADA): Only one payment — 100% by March 15.

How to Calculate Your Advance Tax

Step 1: Estimate your gross income for the full financial year (from all sources)

Step 2: Deduct — standard deduction, HRA (if applicable), 80C, 80D, home loan interest, etc.

Step 3: Calculate tax on net income using applicable slabs (new/old regime)

Step 4: Add surcharge and health & education cess (4%)

Step 5: Subtract TDS already deducted (from bank, rent, etc.)

Step 6: Divide the remaining liability across installments per the schedule

Example: Freelance consultant, New Regime

• Gross receipts: ₹25,00,000
• Business expenses (office, software, travel): ₹5,00,000
• Net Income: ₹20,00,000
• Standard Deduction (new regime): Not applicable
• Tax on ₹20L (new regime): ₹3,37,500 + cess ₹13,500 = ₹3,51,000
• TDS deducted by clients (10% on ₹25L): ₹2,50,000
• Net advance tax liability: ₹1,01,000

Installment schedule:

• June 15: ₹15,150 (15%)
• September 15: ₹45,450 (cumulative 45%)
• December 15: ₹75,750 (cumulative 75%)
• March 15: ₹1,01,000 (100%)

Consequences of Not Paying Advance Tax

Interest under Section 234B

If advance tax paid is less than 90% of the assessed tax, interest at 1% per month (or part of month) from April 1 to the date of assessment is charged.

Interest under Section 234C

If you miss an installment deadline:

• Short payment of 1st/2nd/3rd installment → 1% per month for 3 months
• Short payment of last installment → 1% per month until March 31

Example: You owed ₹1L by September 15 but paid nothing. Interest = 1% × 3 months = 3% × ₹1L = ₹3,000 extra.

How to Pay Advance Tax

1. Go to www.incometax.gov.in → e-Pay Tax
2. Enter PAN and select Challan 280
3. Choose: (0020) Income Tax on Companies (if company) or (0021) Other than Companies
4. Select: (100) Advance Tax
5. Enter tax amount → Complete payment via net banking or UPI
6. Save Challan receipt — required for ITR filing

Advance Tax vs Presumptive Taxation

If you opt for Section 44ADA (professionals with gross receipts up to ₹75L), income is presumed at 50% of gross receipts. Under this scheme:

• Pay entire advance tax in one shot by March 15
• If you miss March 15, the full tax is due by March 31 with Section 234B/234C interest from April

Self-Assessment Tax vs Advance Tax

If you forget advance tax entirely, you will pay Self-Assessment Tax when filing your ITR. The difference:

• Advance tax → paid during the financial year → reduces interest
• Self-assessment tax → paid at ITR filing → full Section 234B and 234C interest applies

Always prioritise advance tax. The interest (effectively 12% p.a.) is higher than most savings instruments.
