TDS on Salary in India: Employer's Guide (2026)

TDS on Salary in India: A Complete Employer's Guide for 2026

Tax Deducted at Source (TDS) on salary is one of the most important — and most misunderstood — responsibilities an employer carries. Every month, when you run payroll, you are not just paying your employees; you are also acting as an agent of the Income Tax Department, withholding tax on the government's behalf and depositing it on time. Get TDS on salary right and the process is invisible. Get it wrong and you expose your business to interest, penalties, disallowed expenses, and frustrated employees who discover at year-end that too little — or too much — tax was deducted from their pay.

This complete guide to TDS on salary in India for 2026 walks you through everything an employer, founder, or payroll manager needs to know: what TDS on salary is, which section of the law governs it, how to calculate it correctly under both the old and new tax regimes, when and how to deposit it, which returns to file, and the common mistakes that trip up even experienced payroll teams. Wherever specific rates or thresholds are involved, treat the figures here as illustrative and always verify the current rates and rules on the official Income Tax Department portal before finalising your payroll.

What Is TDS on Salary?

TDS on salary is the income tax that an employer deducts from an employee's salary each month before paying it, and then deposits with the government on the employee's behalf. The mechanism exists so that tax is collected as income is earned — "pay as you earn" — rather than in one lump sum at the end of the financial year.

The legal basis for TDS on salary in India is Section 192 of the Income Tax Act, 1961. Unlike most other TDS provisions that apply a flat percentage to a payment, Section 192 is unique: the employer must estimate the employee's total taxable salary for the financial year, compute the tax liability on that estimate using the applicable slab rates, and then deduct that annual tax in roughly equal monthly instalments across the year. In other words, TDS on salary is not a fixed rate — it is the employee's projected annual tax spread across twelve months.

Because the deduction is based on an estimate, the employer must keep updating that estimate as the year progresses — when an employee submits investment proofs, changes their declared rent, receives a bonus, or joins or leaves mid-year. This is what makes salary TDS more involved than, say, TDS on a vendor invoice.

Why TDS on Salary Matters for Employers

It is tempting to treat TDS as a back-office formality, but the stakes are real. When you deduct TDS on salary, you become responsible for depositing it correctly and on time. Failure has direct financial consequences:

The employer who fails to deduct or deposit TDS faces interest under Section 201, a penalty, and — critically — the risk that the salary expense itself is disallowed when computing the company's own taxable income. A late deposit attracts interest for every month of delay. Late filing of TDS returns attracts a daily fee. And employees whose Form 16 does not match their Form 26AS will struggle to file accurate returns, generating support tickets and eroding trust in your payroll process.

Beyond compliance, accurate TDS keeps employees happy. Nobody enjoys discovering a large tax shortfall in March because their employer under-deducted all year, and nobody enjoys having too much withheld and waiting months for a refund. Smooth, predictable TDS is a quiet but real part of a good employee experience.

The Two Tax Regimes: Old vs New

Since the introduction of the new tax regime, every salaried employee in India effectively chooses between two systems, and the employer must deduct TDS according to the regime the employee selects. Understanding both is essential.

The old tax regime offers higher slab rates but allows a wide range of deductions and exemptions — House Rent Allowance (HRA), Leave Travel Allowance (LTA), deductions under Chapter VI-A such as Section 80C (investments like PF, ELSS, life insurance, principal on home loans), Section 80D (health insurance), Section 80CCD(1B) (additional NPS), interest on home loans under Section 24, and more. Employees who invest heavily or pay significant rent often pay less tax under the old regime.

The new tax regime offers lower slab rates and a higher basic exemption, but removes most deductions and exemptions. It is designed to be simpler — you pay tax on your gross income with very few adjustments. A standard deduction is available to salaried employees, and the new regime has become the default option, meaning that if an employee does not actively choose the old regime, the employer should deduct TDS under the new one.

For employers, the practical implication is this: at the start of the financial year (or when an employee joins), collect a declaration from each employee stating which regime they choose. Deduct TDS accordingly. If no declaration is received, default to the new regime. Note that an employee can switch regimes at the time of filing their own return, so your TDS is an estimate — but you should still deduct based on their declared choice during the year.

Because the exact slab rates, the standard deduction amount, rebate thresholds, and surcharge rates are revised in the Union Budget from time to time, always confirm the current year's figures from the official sources before configuring your payroll system.

Components of Salary and Their Tax Treatment

To calculate TDS correctly you must understand how each salary component is taxed. A typical Indian salary structure (CTC) includes several heads, each treated differently.

Basic salary is fully taxable. It is also the figure on which many other components and statutory contributions (like Provident Fund) are calculated, so it sits at the centre of the structure.

House Rent Allowance (HRA) is partially exempt under the old regime if the employee actually pays rent, subject to a formula based on the least of: actual HRA received, rent paid minus 10% of basic, and 50% (metro) or 40% (non-metro) of basic. Under the new regime, HRA exemption is not available.

Special allowance is generally fully taxable and is often used as a balancing figure in the CTC.

Leave Travel Allowance (LTA) can be exempt under the old regime for actual travel within India, subject to conditions and frequency limits, with proof of travel.

Provident Fund (employer contribution) within prescribed limits is not taxed at the point of contribution; the employee's own contribution may qualify for Section 80C under the old regime.

Reimbursements such as telephone, fuel, or books may be tax-exempt if supported by bills and structured correctly, though the new regime restricts many of these.

Bonus, incentives, and variable pay are fully taxable in the month they are paid, and a large bonus can push an employee into a higher slab, so the employer should re-estimate TDS when variable pay is disbursed.

Perquisites — benefits like a company car, rent-free accommodation, or interest-free loans — are valued according to specified rules and added to taxable salary.

The standard deduction available to salaried employees reduces taxable salary and is available under both regimes (with the applicable amount differing by year and regime), so make sure your payroll engine applies it.

How to Calculate TDS on Salary: Step by Step

Here is the practical, repeatable process every payroll team should follow to compute TDS on salary for an employee. We will walk through it as a sequence of steps.

Step 1: Estimate Gross Annual Salary

Project the employee's total salary for the full financial year (April to March). Include basic, all allowances, expected bonus and variable pay, and the taxable value of perquisites. For a new joiner, include only the months they will be employed in the current year, and ask whether they had previous employment in the same year (their prior income affects the total).

Step 2: Subtract Exemptions (Old Regime)

If the employee has chosen the old regime, subtract eligible exemptions such as the HRA exemption (based on rent paid), LTA, and any other exempt allowances for which the employee has provided declarations or proof. Under the new regime, skip most of these.

Step 3: Apply the Standard Deduction

Reduce the figure by the standard deduction available to salaried employees for the relevant regime and year. This gives you income under the head "Salaries."

Step 4: Add Other Declared Income

If the employee has declared other income — for example, interest income or income from house property (including a home loan interest set-off, which can reduce taxable income under the old regime) — incorporate it. Employees commonly declare home loan interest to lower their TDS.

Step 5: Subtract Chapter VI-A Deductions (Old Regime)

Under the old regime, subtract eligible deductions: Section 80C investments (up to the prescribed ceiling), 80D health insurance, 80CCD(1B) NPS, 80E education loan interest, 80G donations where applicable, and others — but only to the extent the employee has declared and will substantiate them. Under the new regime, most Chapter VI-A deductions are not available, though the employer's NPS contribution under 80CCD(2) remains allowable within limits.

Step 6: Arrive at Taxable Income and Apply Slab Rates

The result is the employee's estimated taxable income. Apply the slab rates of the chosen regime to compute the gross tax. Add the applicable health and education cess. Apply any surcharge if the income crosses the relevant high-income thresholds. Apply the rebate if the employee's income is within the rebate limit, which can reduce the tax to nil for lower incomes.

Step 7: Divide Across Remaining Months

Subtract any TDS already deducted earlier in the year, then divide the remaining annual tax by the number of months left in the financial year. That monthly figure is the TDS to deduct from the current month's salary. Recompute this every month, because estimates change as proofs arrive and pay varies.

A Simple Worked Example

Suppose an employee's estimated annual taxable income after all deductions works out to a figure on which the computed annual tax (including cess) is ₹60,000. If this is determined in April with twelve months remaining, the employer deducts ₹5,000 per month. If, in January, the employee submits investment proofs that reduce the annual tax to ₹48,000, and ₹45,000 (₹5,000 × 9) has already been deducted from April to December, then only ₹3,000 remains, spread across January, February, and March — i.e., ₹1,000 per month. This dynamic re-estimation is the heart of Section 192. (The numbers here are purely illustrative; your real figures depend on current slab rates.)

Collecting Investment Declarations and Proofs

The accuracy of TDS depends heavily on information the employee provides. At the start of the year, employers collect an investment declaration (often via Form 12BB or an equivalent in your payroll software), in which the employee states their planned investments, rent paid, home loan interest, and other deductions. The employer deducts TDS based on these declarations through the year.

Toward the end of the year — usually in January or February — the employer asks employees to submit actual proofs: rent receipts, investment statements, insurance premium receipts, home loan certificates, and so on. The employer verifies these proofs and finalises the TDS for the remaining months. Declarations not backed by proof are disregarded, which usually increases the tax payable in the final months.

A clean declaration-and-proof cycle prevents nasty surprises. Build clear internal deadlines, communicate them early, and use your HRMS to collect and validate documents digitally rather than chasing paper.

Depositing TDS and Filing Returns

Deducting TDS is only half the job; depositing and reporting it correctly is the rest.

Depositing TDS. TDS deducted in a month must be deposited with the government by the prescribed due date of the following month (with a special extended date for the deduction made in March). Deposit is made electronically using a challan, quoting the company's TAN (Tax Deduction and Collection Account Number). Every employer who deducts TDS must hold a valid TAN; quoting it correctly on challans and returns is essential because it links the deposit to your account.

Filing quarterly TDS returns. Employers file a quarterly TDS statement for salary deductions — Form 24Q — reporting the details of salary paid and tax deducted for each employee. Form 24Q has annexures that capture employee-wise breakups, and the fourth-quarter return includes the full annual salary detail used to generate Form 16. File each quarter's return by its due date to avoid the daily late-filing fee.

Issuing Form 16. After the year ends, the employer issues Form 16 to each employee — a certificate of the salary paid and TDS deducted, in two parts (Part A from the TRACES portal showing tax deposited, and Part B with the detailed salary computation). Employees use Form 16 to file their income tax returns. Issue it by the prescribed deadline after the financial year closes.

Reconciling with Form 26AS and AIS. The TDS you deposit and report shows up in the employee's Form 26AS and Annual Information Statement. Mismatches — caused by wrong PAN, wrong assessment year, or unfiled returns — cause employees real problems at filing time. Verifying PANs at onboarding and reconciling deposits with returns each quarter prevents most of these issues.

Consequences of Getting TDS Wrong

Because so much rides on TDS, it is worth being explicit about what happens when it goes wrong.

If an employer fails to deduct TDS, or deducts but fails to deposit it, interest accrues under Section 201 for the period of default — a separate rate applies for failure to deduct versus failure to deposit after deduction. The employer may also be treated as an "assessee in default" and, in serious cases of non-deposit of deducted tax, face prosecution. Separately, late filing of the quarterly return attracts a fee for each day of delay (capped at the TDS amount), and incorrect returns can attract a penalty. Finally, salary on which TDS was required but not deducted can be partially disallowed as a business expense, increasing the company's own tax. None of these outcomes is catastrophic if you run a disciplined process, but all are entirely avoidable.

Best Practices for Managing Salary TDS

Getting TDS right is less about heroics in March and more about a steady process all year. The following practices keep payroll teams out of trouble.

Collect a regime declaration and an investment declaration from every employee at the start of the year and from every new joiner on day one. Validate PAN and personal details at onboarding so that deposits map correctly to each employee. Re-estimate TDS every single month rather than annually, so bonuses, mid-year hikes, and updated declarations are absorbed gradually instead of creating a March shock. Set firm internal deadlines for proof submission and communicate them well in advance. Deposit TDS by the due date every month and file Form 24Q on time each quarter. Reconcile your deposits and returns regularly so that Form 16 and Form 26AS agree. And keep documentation — declarations, proofs, challans, and returns — organised and retrievable in case of any query from the tax authorities.

Automating these steps in a modern HRMS removes most of the manual risk. A good payroll system computes TDS under both regimes, applies the latest slab rates, collects declarations and proofs digitally, generates challans and Form 24Q-ready data, and produces Form 16 at year-end — all while keeping an audit trail.

Special Situations Every Payroll Team Faces

Standard month-to-month TDS is straightforward once configured, but real payroll throws up situations that need careful handling. Knowing how to treat them prevents both under-deduction and unfair over-deduction.

Bonus, arrears, and lump-sum payments. When a large bonus, incentive, or arrears from a salary revision is paid, it increases the employee's taxable income for the year, sometimes pushing them into a higher slab. The correct approach is to re-estimate the annual tax including the lump sum and spread the additional tax across the remaining months, rather than deducting it all in one shock. Where arrears relate to earlier years, the employee may be eligible for relief under Section 89, computed using Form 10E, which the employee files; the employer can factor in such relief if properly informed, but the responsibility for claiming it ultimately rests with the employee.

Employees without a valid PAN. If an employee does not furnish a valid PAN, TDS must be deducted at a higher rate as prescribed by law, and the employee will face difficulties getting credit for the tax. Verifying PAN at onboarding and ensuring it is linked correctly is therefore not a formality but a financial protection for the employee.

Lower or nil deduction. In certain cases an employee can obtain a certificate from the Assessing Officer permitting tax to be deducted at a lower rate or not at all. If an employee presents such a valid certificate, the employer follows it. Absent that, TDS follows the normal computation.

Multiple employers in one year. An employee who works for more than one employer in a year — sequentially or simultaneously — should declare details of the other salary so that total tax is estimated correctly. For sequential employment, Form 12B is used to report the previous employer's salary and TDS. Without this disclosure, each employer deducts only on the salary it pays, often leaving a shortfall the employee must settle when filing.

Perquisites in detail. Benefits beyond cash salary — a company-provided car, rent-free or concessional accommodation, interest-free or concessional loans, employer-paid club memberships, stock options on exercise, and similar — are "perquisites" valued under specified rules and added to taxable salary. Because perquisite valuation can be intricate, payroll teams should configure these carefully and keep documentation, as they are a common area of error.

TDS Versus Advance Tax: Clearing the Confusion

Employees sometimes confuse TDS with advance tax. TDS on salary is deducted by the employer from salary income. Advance tax is paid directly by the taxpayer, in instalments through the year, on income that is not subject to TDS — such as significant capital gains, business income, or large interest and rental income. A salaried employee whose only income is salary, with TDS correctly deducted, usually has no advance-tax obligation. But an employee with substantial other income may need to pay advance tax themselves on that portion, because the employer only withholds on salary. Communicating this distinction — ideally by encouraging employees to declare other income so it can be factored into salary TDS where they wish — prevents interest surprises for the employee at filing time.

How an HRMS Automates Salary TDS

Everything described in this guide can be done by hand, but it is slow and error-prone at any meaningful headcount. A modern HR and payroll platform automates the entire TDS lifecycle, which is why most growing organisations move off spreadsheets.

A good system lets each employee select their tax regime and submit investment declarations digitally, applies the current year's slab rates, standard deduction, rebate, surcharge, and cess automatically, and computes TDS under both regimes so the employee can see the comparison. It recalculates TDS every month as declarations, proofs, bonuses, and salary changes flow in, so the deduction adjusts smoothly rather than spiking at year-end. It collects and stores proofs against declarations, flags shortfalls, and prompts employees before deadlines. It generates the data needed for monthly challans and quarterly Form 24Q, and produces Form 16 for every employee at year-end with the full computation. And it keeps a complete audit trail of every calculation and deposit, which is invaluable if any query arises. The net effect is fewer errors, on-time compliance, less manual effort, and employees who trust that their tax is being handled correctly.

A Year-Round TDS Calendar at a Glance

It helps to think of salary TDS as a rhythm across the financial year rather than a year-end task. Early in the year (around April), collect regime choices and investment declarations from all employees and new joiners, and begin deducting based on those estimates. Through the middle of the year, deposit TDS by the due date each month and file the quarterly Form 24Q for each completed quarter. As the year nears its end (around January to February), collect actual investment and rent proofs, verify them, and finalise the remaining months' deductions. After the year closes (around the new April to May/June window), deposit the final month's TDS, file the fourth-quarter return, and issue Form 16. Reconciling deposits with returns throughout keeps Form 16 and Form 26AS in agreement. This steady cadence is what turns TDS from a stressful scramble into a quiet, predictable routine.

TDS on Salary: Frequently Asked Questions

1. Is TDS deducted on every salary? Not necessarily. TDS is deducted only if the employee's estimated annual taxable income exceeds the basic exemption limit after eligible deductions and rebate. An employee whose tax works out to nil — for instance, because the rebate covers their entire liability — will not have TDS deducted, provided their declarations are accurate.

2. Which regime should the employer use to deduct TDS? The employer deducts according to the regime the employee declares. If the employee does not declare a choice, the new tax regime applies by default. The employee can still switch when filing their own return, but the employer must follow the declared choice during the year.

3. What if an employee joins mid-year from another company? Ask the new employee for details of salary earned and TDS deducted at the previous employer (commonly via Form 12B). Including prior income ensures the total tax is estimated correctly and prevents a large shortfall at year-end. If the employee does not disclose previous income, you compute TDS only on the salary you pay, and any gap is settled when they file their return.

4. Can an employee reduce their TDS legally? Yes — by declaring eligible deductions and exemptions (under the old regime) and by reporting deductible home loan interest, which lowers taxable income. The employee must be able to substantiate these with proof. Declaring planned investments early in the year spreads the benefit across more months.

5. What is the difference between Form 16 and Form 26AS? Form 16 is the certificate the employer issues showing salary paid and TDS deducted. Form 26AS (and the AIS) is a consolidated tax statement maintained by the tax department showing all tax credited against the employee's PAN from all sources. The two should match for salary; a mismatch usually points to a filing or PAN error that the employer should fix.

6. What happens if the employer deducts TDS but does not deposit it? This is a serious default. The employee still gets credit only when it appears in Form 26AS, so non-deposit harms the employee, and the employer faces interest, potential penalty, and in egregious cases prosecution. Deducted tax must always be deposited by the due date.

7. Do I need a TAN to deduct TDS on salary? Yes. Any employer deducting TDS must obtain a TAN and quote it on all challans, returns, and certificates. Operating without a valid TAN, or quoting it incorrectly, leads to processing errors and penalties.

8. How often should TDS be recalculated? Every month. Because Section 192 works on a running estimate, recalculating monthly lets you absorb changes — new declarations, bonuses, salary revisions, or resignations — smoothly, rather than forcing a large adjustment in the final months of the year.

Conclusion

TDS on salary sits at the intersection of payroll, compliance, and employee trust. The mechanics of Section 192 — estimate the annual tax, deduct it in monthly instalments, keep re-estimating as the year unfolds, deposit on time, and report it accurately — are not difficult once you have a disciplined process in place. The pitfalls almost always come from doing TDS once a year instead of every month, from missing deposit or return deadlines, and from poor collection of declarations and proofs.

The good news is that none of this needs to be manual. A modern HR and payroll platform handles regime selection, applies the current slab rates, calculates TDS month by month, collects declarations and proofs digitally, generates the data for your challans and Form 24Q, and produces Form 16 at year-end — all with a clean audit trail. If your team is still wrestling with spreadsheets every payroll cycle, it may be time to let software carry the load. Try CozyHR to automate TDS on salary, statutory compliance, and the rest of your payroll, so you can spend less time on tax arithmetic and more time on your people.
