Advance tax 15 December is the third instalment date for tax year 2026–27, and the advance tax due date that salaried people with extra income, freelancers and investors most often miss. This guide explains who must pay, how the 75% rule works with a worked example, and what interest applies if you fall short. It is general information, not personal tax advice.
Key Takeaways
- 75% by 15 December. The third instalment is cumulative: by 15 December 2026 you should have paid at least 75% of your estimated advance tax for tax year 2026–27 in total, not an extra 75%.
- Not everyone pays. Advance tax applies when the estimated liability after TDS is ₹10,000 or more; resident individuals aged 60 or above with no business income are exempt.
- Delay costs interest. Shortfalls attract interest under sections 424 and 425 of the Income-tax Act, 2025, so estimate early and revise before 15 March.

A Small Payment Today Can Protect Your Financial Peace Tomorrow – Understand Advance Tax, Plan Legally and Save Yourself from Last-Minute Stress.
Every rupee we earn carries a story. It represents months of hard work, long working hours, business risks, professional commitments, family responsibilities and personal sacrifices. Whether someone earns a salary, runs a small business, works as a consultant, receives rent, invests in shares or earns interest from fixed deposits, that income has been earned through effort and discipline.
But there is one responsibility that many taxpayers remember only when the financial year is almost over: Advance Tax.
For the financial year 2026–27, 15 December 2026 is an important deadline. By this date, eligible taxpayers must generally have paid at least 75% of their estimated annual tax liability, after considering applicable tax deducted at source (TDS) and other tax credits.
This is not merely a tax payment date. It is an opportunity to review income, correct mistakes, plan legitimate tax savings and avoid unnecessary interest.
The real question is not simply whether we have enough money to pay tax. It is whether we have managed our income intelligently throughout the year.
\n1. What Is Advance Tax and Why Does the Government Collect It Before the Year Ends?
Advance Tax means paying income tax during the financial year in which income is earned, rather than waiting until the year ends.
It is often described as the “pay-as-you-earn” system.
For example, if a person expects to earn taxable income during Tax Year 2026–27, the applicable tax should generally be paid in instalments during that same tax year.
The system helps the government receive revenue throughout the year. For taxpayers, it encourages financial discipline and prevents a large tax burden from arriving unexpectedly at the end of the year.
However, advance tax is not applicable to everyone. Generally, an individual whose estimated net tax liability for the year is ₹10,000 or more must pay advance tax, after taking eligible TDS and other tax credits into account.
A resident senior citizen aged 60 years or above who does not have income from business or profession is generally exempt from paying advance tax.
\n2. Why 15 December Matters: The 75% Responsibility
Under the regular advance-tax schedule prescribed by the Income-tax Act, 2025, the payment requirements are cumulative.
| Due date | Cumulative percentage of estimated advance tax |
|---|---|
| 15 June 2026 | 15% |
| 15 September 2026 | 45% |
| 15 December 2026 | 75% |
| 15 March 2027 | 100% |
Remember: 75% is the total amount that should have been paid by 15 December, not an additional 75% instalment.
For example:
Suppose your estimated total tax liability for the year is ₹1,00,000 and your expected TDS and other eligible tax credits are ₹20,000.
Your estimated advance-tax liability is ₹80,000.
By 15 December, the cumulative payment requirement is:
75% of ₹80,000 = ₹60,000.
If you have already paid ₹36,000 in earlier instalments, you need to pay another ₹24,000 by 15 December to reach the required cumulative amount.
This is only an illustrative calculation. Actual liability depends on the taxpayer’s income, deductions, tax regime, credits and applicable provisions.
\n3. Salary Earners: Don’t Assume Your Employer Has Paid All Your Tax
Many salaried employees believe that once their employer deducts TDS every month, their tax responsibility is over.
That assumption can be costly.
TDS on salary may cover the tax arising from salary income, but it may not cover additional income earned during the year.
Consider a bank employee or government employee who receives:
- Salary and allowances.
- Interest from bank fixed deposits.
- Savings-account interest.
- Rental income from a residential property.
- Interest from bonds or other investments.
- Capital gains from shares, mutual funds or property.
- Income from freelance work or consultancy.
If the total tax liability exceeds the TDS and other eligible credits, additional advance tax may become payable.
Practical guidance: Review your Form 16, salary slips, bank interest certificates, investment statements and rental receipts. Do not wait until your employer prepares the final tax computation.
A small review today can prevent an unpleasant tax surprise tomorrow. Our list of salaried investor mistakes shows how easily income outside the payslip gets ignored.
\n4. Business Owners and Professionals: Profit Is Not the Same as Cash in Hand
Business owners, shopkeepers, traders, consultants, doctors, lawyers, architects and freelancers often focus on sales and cash flow.
But income tax is calculated on taxable income, not merely on the money available in the bank account.
A business may have substantial receipts but also expenses, stock costs, salaries, rent, depreciation and other allowable deductions.
Similarly, a professional may receive consultancy fees throughout the year, but the taxable profit must be calculated after considering eligible business or professional expenses.
Advance-tax planning should therefore involve:
- Estimating annual turnover and taxable profit.
- Reviewing business expenses and supporting documents.
- Considering depreciation and other allowable deductions.
- Accounting for TDS received from clients.
- Reviewing income from multiple businesses or professional activities.
- Updating the estimate when business conditions change.
Eligible taxpayers using specified presumptive-taxation schemes under the law generally have a special facility to pay their entire advance tax by 15 March instead of following the regular quarterly schedule. They should verify their eligibility and applicable conditions.
\n5. Rental Income: Your Property May Be Earning, But Is Your Tax Planning Ready?
A person receiving monthly rent may feel that the rental income is simply additional household income.
However, rental income is generally taxable under the head “Income from House Property”, subject to applicable rules and deductions.
For example, a person earning ₹25,000 per month receives ₹3 lakh in annual rent.
The taxable amount is not automatically ₹3 lakh. The calculation may allow deductions under the applicable house-property provisions, including the standard deduction and eligible interest on borrowed capital, subject to conditions.
If the final tax liability after TDS and other credits reaches the advance-tax threshold, advance tax may be required.
Practical guidance: Keep rent agreements, property-tax receipts, housing-loan interest certificates and records of rent received. Review the tax impact before spending the entire rental income.
\n6. Capital Gains: Investment Profits Can Create an Unexpected Tax Liability
Investment income is another area where taxpayers frequently make mistakes.
People may invest in shares, mutual funds, bonds, gold, land or residential property. When they sell these assets at a profit, capital gains tax may arise.
Examples include:
- Profit from selling listed shares.
- Gains from equity or debt mutual funds.
- Profit from selling land or residential property.
- Gains from selling gold or other capital assets.
- Gains from certain securities and investment instruments.
The applicable tax rate depends on the nature of the asset, holding period, acquisition date, transfer date and other statutory conditions.
For example, qualifying short-term gains on specified listed equity investments and qualifying long-term gains may be taxed at special rates. Exemptions or relief may also be available in certain situations if the statutory conditions are satisfied.
Do not assume that tax will automatically be deducted when you sell an investment. In many cases, the responsibility to calculate and pay the tax remains with the taxpayer.
Practical guidance: Maintain a record of purchase cost, sale value, brokerage, holding period and eligible exemption documents. If you sell property or investments during the year, revise your advance-tax estimate.
\n7. Interest, Dividends and Other Income: Small Receipts Can Become a Big Tax Liability
Many taxpayers overlook income that does not arrive as monthly salary.
Examples include:
- Fixed-deposit interest.
- Recurring-deposit interest.
- Savings-account interest.
- Interest from bonds and debentures.
- Dividend income.
- Family pension, where taxable.
- Winnings and other taxable receipts.
- Income from certain digital-asset transactions, subject to special provisions.
A bank may deduct TDS on certain interest payments, but TDS does not necessarily settle the taxpayer’s entire liability.
For example, a retired person receiving pension may also have substantial fixed deposits. If the total taxable income creates additional tax liability beyond the tax already deducted, further payment may be required.
Practical guidance: Collect interest certificates from banks and financial institutions, and see how repo rate changes affect your deposit interest before parking more money in taxable interest. Check dividend statements and other income records. Do not ignore small amounts simply because they arrive from different sources.
\n8. Digital Assets and New-Age Income: Don’t Ignore the Tax Rules
Digital assets and virtual digital assets have created new opportunities as well as new tax responsibilities.
Transactions involving specified virtual digital assets may attract special tax provisions and TDS requirements.
Taxpayers should not assume that gains from digital assets are treated like ordinary bank interest or salary.
Maintain transaction records, purchase values, sale values, applicable TDS details and exchange statements. Take professional advice where the transactions are complex.
The tax treatment of each income category must be checked under the applicable provisions. A general tax-saving deduction cannot automatically be used to reduce income taxed under special-rate provisions.
\n9. Lawful Tax Planning: Save Tax Without Breaking the Law
Tax planning is not tax evasion. It is the intelligent use of benefits and deductions permitted by law.
The first decision is to understand the difference between the old and new tax regimes.
The new tax regime is the default regime under the current framework. The old regime may be beneficial for eligible taxpayers who can claim specified deductions and exemptions.
The right choice depends on income, eligible deductions, exemptions, family responsibilities and financial goals.
Some lawful tax-planning opportunities to examine include:
A. Retirement planning
Eligible contributions to recognised retirement schemes and pension arrangements may provide tax benefits, depending on the selected regime and applicable provisions. See the NPS withdrawal rules and our guide to retirement planning in India.
B. Health insurance
Eligible health-insurance premiums may provide deductions under the old tax regime, subject to statutory limits and conditions.
C. Home-loan planning
Interest and principal repayment on an eligible housing loan may offer tax benefits under specified conditions. The availability and extent of these benefits depend on the applicable regime and the nature of the property.
D. Education-loan interest
Eligible interest paid on an education loan may qualify for deduction under the old tax regime, subject to statutory conditions.
E. Donations
Donations to eligible institutions and funds may qualify for deductions where the prescribed conditions, payment methods and documentation requirements are met.
F. Capital-gains exemptions
Certain exemptions may be available when capital gains are reinvested in eligible assets within prescribed time limits. These provisions are conditional and require careful planning.
G. Business and professional expenses
Genuine expenses incurred wholly and exclusively for eligible business or professional purposes may be deductible, subject to the law and proper documentation.
Important: Do not purchase an unsuitable insurance policy, make an unnecessary investment or borrow money merely to obtain a tax deduction. Saving tax is beneficial only when the underlying financial decision is sensible.
\n10. Old Regime or New Regime: Choose With a Calculator, Not With Emotion
Many taxpayers continue with the same tax regime simply because they selected it in an earlier year.
But financial circumstances change.
A person may have a housing loan one year, additional investments the next year, and different income sources later.
The old regime may be beneficial for someone with substantial eligible deductions and exemptions. The new regime may be more beneficial for someone with fewer deductions and a simpler financial structure.
Before making a decision:
- Calculate tax under both regimes.
- Include all income, not just salary.
- Include only deductions actually available under each regime.
- Consider eligible exemptions and special-rate income.
- Compare the final tax payable, not merely the headline tax rates.
- Check the rules governing regime selection and switching, particularly if you have business or professional income.
The lowest tax figure should not be the only consideration. Your investment should also serve your family’s long-term financial needs.
\n11. What Happens If You Delay or Underpay Advance Tax?
Ignoring advance tax does not make the liability disappear.
Interest may become payable under the applicable provisions of the Income-tax Act, 2025.
Broadly:
- Section 424 deals with interest for certain defaults in payment of advance tax.
- Section 425 deals with interest for deferment of advance-tax instalments.
The calculations depend on the nature and timing of the shortfall, tax credits and statutory conditions. Interest is generally calculated at the prescribed monthly rate, often 1% for a month or part of a month under the relevant provisions.
There may be exceptions and relief in specified circumstances. Taxpayers should check the exact calculation rather than assuming that every shortfall attracts the same amount.
The financial cost is only one part of the problem. Last-minute tax payments can disturb household budgets, planned investments, loan repayments and emergency savings.
A person who could have paid a manageable amount in instalments may suddenly face a much larger payment with additional interest.
\n12. A Practical Advance-Tax Action Plan Before 15 December
Instead of waiting for the last day, take a structured approach.
Step 1: List every source of income.
Include salary, pension, business profit, professional receipts, rent, interest, dividends, capital gains and other taxable income.
Step 2: Estimate your full-year income.
Use actual income received so far and a reasonable estimate for the remaining months.
Step 3: Calculate taxable income.
Apply the correct rules, deductions, exemptions and special tax rates.
Step 4: Compare both tax regimes.
Choose the regime that is legally available and financially suitable.
Step 5: Deduct TDS and other eligible tax credits.
Review Form 26AS, AIS and other relevant records. Do not assume that every tax credit shown in an estimate has already been correctly reflected.
Step 6: Calculate the cumulative advance-tax requirement.
By 15 December, the regular cumulative requirement is 75% of the estimated advance-tax liability.
Step 7: Pay through the official income-tax e-filing portal.
Use the correct assessment/tax-year details and payment category. Verify the challan and save the payment receipt.
Step 8: Review again before 15 March.
Income may change due to bonuses, business profits, property sales, interest receipts or other transactions. Update the estimate and pay the remaining amount as required.
\n13. The Psychological Benefit: Financial Peace Is Also a Form of Wealth
There is a psychological difference between a person who plans tax payments and a person who avoids thinking about them.
The first person knows the approximate liability, keeps money aside and makes decisions calmly.
The second person may continue spending, investing or making commitments without understanding the tax consequences. When the deadline arrives, anxiety begins.
This anxiety can affect family discussions, savings decisions and even personal relationships.
Tax planning provides several emotional benefits:
- Control: You know your approximate tax responsibility instead of fearing an unknown amount.
- Confidence: You can make investment and spending decisions with a clearer picture of your finances.
- Discipline: Setting aside money for tax encourages responsible budgeting.
- Peace of mind: You avoid unnecessary last-minute pressure and reduce the risk of avoidable interest.
- Family security: Money reserved for tax is not mistakenly spent on other commitments.
- Responsible citizenship: Paying the correct tax supports public infrastructure, education, healthcare and national development.
There is also a deeper satisfaction in knowing that you have fulfilled your responsibility honestly.
A taxpayer should not feel that tax planning is merely an exercise in reducing government revenue. It is about paying what is legally due, claiming what the law legitimately allows and protecting the remaining income through sensible financial management.
\n14. A Simple December Checklist for Every Taxpayer
Before 15 December 2026, ask yourself:
- Have I included all my sources of income?
- Have I estimated my income for the full tax year?
- Have I checked salary and other TDS credits?
- Have I reviewed bank and fixed-deposit interest?
- Have I included rental income?
- Have I calculated capital gains from shares, mutual funds or property?
- Have I compared the old and new tax regimes?
- Have I checked whether my deductions and exemptions are legally available?
- Have I calculated the 75% cumulative advance-tax requirement?
- Have I saved the payment receipt and supporting documents?
If the answer to any of these questions is no, there is still an opportunity to review your position before the deadline.
Conclusion: Your Hard-Earned Money Deserves Intelligent Planning
We spend years building our careers, growing businesses, investing savings and securing our family’s future. We carefully compare prices before buying a household appliance, negotiate interest rates before taking a loan and think several times before making a major purchase.
Then why should we ignore tax planning, which directly affects the money we retain from our earnings?
15 December is not just another date on the financial calendar. It is a reminder that financial responsibility begins before a liability becomes a problem.
Do not wait for the financial year to end. Do not treat tax as an unpleasant surprise. Do not make hurried investments merely to reduce tax. Understand your income, calculate your liability, use lawful tax benefits and pay on time.
The purpose of earning is not simply to accumulate money. It is to build security, dignity and peace of mind for ourselves and our families.
Paying the correct tax is a responsibility. Planning it intelligently is financial wisdom. And sleeping peacefully after fulfilling both is a satisfaction that money alone cannot buy.

Frequently asked questions
What is the advance tax due date on 15 December 2026?
For tax year 2026–27 the third instalment is due on 15 December 2026. By then you should have paid at least 75% of your estimated advance tax in total, after adjusting TDS and other tax credits.
Who has to pay advance tax?
Anyone whose estimated tax after TDS is ₹10,000 or more for the year. A resident individual aged 60 or above with no income from business or profession is exempt.
How do I calculate advance tax?
Estimate your total income, compute tax under your chosen regime, subtract expected TDS and other credits, and pay the balance in instalments: 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March. You can revise the estimate in later instalments.
Can I pay advance tax after 15 December?
Yes, but a shortfall can attract interest for deferment under section 425. Advance tax paid up to 31 March still counts as advance tax for that year, so paying early limits the interest.
What is the interest if I miss advance tax?
Section 424 charges simple interest at 1% per month if you have paid less than 90% of your assessed tax. Section 425 charges interest on instalment shortfalls, generally 3% on the 15 June, 15 September and 15 December shortfalls and 1% on the 15 March shortfall. The exact amount depends on your return.
Do salaried employees need to pay advance tax?
Only if tax on income outside salary, such as interest, rent, capital gains or freelance income, leaves a liability of ₹10,000 or more after TDS. Check Form 26AS and AIS for TDS credits first.
