Freelancers and consultants in India pay tax in 4 advance installments instead of monthly TDS like salaried employees. Missing the deadlines triggers section 234B/234C interest. This calculator builds your quarterly schedule from your annual income estimate, factoring TDS already deducted by clients.
What is Freelancer Tax?
Freelancers receive payments under Section 194J (10% TDS deducted by clients). For most freelancers in 20-30% slabs, this 10% TDS is short of actual liability, leaving the rest to pay as advance tax. The Income Tax Act mandates four installments — 15 June (15%), 15 September (45% cumulative), 15 December (75%), 15 March (100%).
Missing or under-paying these installments triggers Section 234C interest at 1% per month on the shortfall, plus Section 234B interest of 1% per month from April 1 if total advance + TDS is below 90% of liability. The combination can easily add ₹20-50K of avoidable cost on a typical professional's tax bill.
How the schedule is calculated
Step 1: estimate annual income (gross receipts minus business expenses if you claim them). Step 2: compute tax under chosen regime including standard deduction not applicable (Section 44ADA presumptive scheme allows 50% deemed expenses for professionals up to ₹50L turnover). Step 3: subtract expected TDS. Step 4: split the remainder across 4 installments at 15/45/75/100%.
The calculator handles both old and new regime, and shows the optional 44ADA presumptive route for eligible professionals (doctors, lawyers, CAs, consultants, technical professionals) up to ₹50L gross receipts.

How to use this calculator
Enter annual gross receipts
Total billing across all clients in the financial year. Use a realistic estimate based on year-to-date and pipeline.
Enter business expenses or use 44ADA
Either claim actual expenses (need books of accounts) or use 44ADA presumptive scheme (50% deemed expenses, no books needed) if eligible — applies to most consultants, doctors, lawyers, technical professionals up to ₹50L turnover.
Choose regime and enter deductions
New regime: lower slabs, no 80C/80D. Old regime: higher slabs, full deductions. New regime usually wins for freelancers under ₹15L without major deductions.
Enter expected TDS
Sum of 10% TDS deducted by all clients during the year. Cross-check against Form 26AS quarterly to ensure clients are depositing correctly.

When to use it
First-year freelancer planning
Most new freelancers don't know about advance tax until they get a notice. Run the calculator at the start of each year with conservative estimates; pay each quarter; reconcile at year-end with actual income.
Variable-income freelancers
Income spikes mid-year (a big project, year-end retainers) shift the tax. Re-run the calculator after each major billing event and adjust the next installment to true up.
Comparing 44ADA vs actual expenses
44ADA assumes 50% expenses with zero paperwork. If your actual expenses are lower than 50% of receipts (very common), 44ADA saves both tax and audit hassle. If actual expenses exceed 50%, claiming actuals saves more tax but requires books.
Common mistakes to avoid
Assuming 10% TDS covers full liability
TDS at 10% is short for anyone in 20-30% slabs. Compute actual liability, subtract TDS, the rest is advance tax. Don't wait for filing time.
Skipping Q1 and Q2 because 'I'll pay everything in March'
Each missed installment owes Section 234C interest, regardless of total paid by year-end. Pay each quarter on time.
Forgetting GST registration above ₹20L
Freelancer with annual receipts above ₹20L must register for GST and charge 18% GST on services. Income tax is separate; GST is in addition. Don't conflate the two.
