What is TDS on Salary and Why It Matters

Tax Deduction at Source (TDS) on salary is pretty straightforward—it's the tax your employer withholds from your monthly salary and deposits directly with the income tax department. Think of it as an advance payment toward your annual income tax liability.

And here's the thing: every employer in India is compelled to deduct TDS from employee salaries. It doesn't matter if your company is a startup, a mid-sized firm, or a large corporation. The rules apply equally. So what does this mean for you? Well, if you're an employee, you need to understand how much tax gets deducted and why. If you're an employer, you need to get the calculations right or face serious penalties.

The TDS framework for salary is governed under Section 192 of the Income Tax Act, 1961. It's one of the most common forms of TDS because salary is the most regular source of income for millions of Indians.

TDS Rates and Slabs for 2026

In 2026, TDS on salary is calculated based on the income tax slabs applicable to that financial year. But here's where it gets interesting—the slab structure for 2026 will likely follow the new tax regime introduced in recent years, unless the government makes changes.

Let me break down how this works. Your employer doesn't just pick a random percentage. Instead, they use the tax tables provided by the income tax department. These tables factor in your expected annual salary and calculate the monthly TDS accordingly.

These are indicative rates. The actual TDS deducted will depend on your Form 12BB submission and the tax tables issued by the income tax department for 2026.

Who Needs to File Form 12BB and When

Form 12BB is your declaration to your employer about your expected income for the financial year. Basically, it's how you tell your HR department how much tax should be deducted from your salary.

But here's the catch—not everyone needs to file it. If your total income (including salary from multiple employers) won't exceed the basic exemption limit, you can claim exemption from TDS. And that's really it. You just need to submit Form 12BB before the financial year starts or within 15 days of joining a new employer.

• You must file Form 12BB if your total income is expected to exceed the exemption limit
• You should file it even if you have multiple employers and earn from other sources
• If you don't file it, TDS will be deducted at the maximum rate
• You can revise your Form 12BB if your income estimate changes mid-year
• Keep a copy for your records and tax filing purposes

TDS Exemption Limits for 2026

The basic exemption limit for 2026 under the new tax regime remains at Rs. 3 lakh. But wait—there's more to it than just that single number.

If your total annual income (salary plus income from other sources) is expected to be less than Rs. 3 lakh, you don't need to pay any income tax. So naturally, your employer shouldn't deduct any TDS either. To claim this exemption, you need to submit Form 12BB to your employer.

Now, what if you earn from multiple sources? Say you get salary from one employer and rental income from a property. In that case, your total income from all sources is what matters. Put simply, if your combined income stays below Rs. 3 lakh, you can claim exemption from TDS on salary.

Practical Example: How TDS is Calculated

Let's walk through a real scenario to make this clearer. Say Rohit works at a tech company and earns a monthly salary of Rs. 60,000. That's Rs. 7.2 lakh annually. He has no other income sources.

Rohit's expected annual income is Rs. 7.2 lakh. Under the new tax regime for 2026, he falls in the 5% slab (Rs. 3 lakh to Rs. 7.5 lakh). So his total annual tax liability would be roughly Rs. 21,000. Spread across 12 months, that's about Rs. 1,750 TDS per month.

But here's where it gets practical. The income tax department provides tax tables that employers use. These tables already account for monthly income and calculate TDS accordingly. So Rohit's employer doesn't manually calculate—they just refer to the table and deduct the right amount.

Now, what if Rohit gets a bonus in December of Rs. 2 lakh? His total annual income jumps to Rs. 9.2 lakh. Now he's in the 10% bracket. His employer might need to adjust the TDS deduction for the remaining months or for the bonus itself.

Responsibilities of Employers

Employers have serious responsibilities when it comes to TDS. And I'm not exaggerating—getting this wrong can lead to penalties, interest, and legal trouble.

First, you need to deduct TDS at the right rate using the prescribed tax tables. Second, you must deposit the deducted amount with the government within specific timelines. Third, you're responsible for issuing Form 16 (or Form 16A) to employees before June 30 of the following financial year.

• Deduct TDS from salary based on tax tables or Form 12BB submitted by the employee
• Deposit TDS with the government by the 7th of the following month (or 10th if depositing via challan)
• Maintain proper records of TDS deducted for each employee
• File quarterly TDS returns (quarterly TDS statement) with the income tax department
• Issue Form 16 to each employee by June 30 of the following financial year
• Ensure TDS deduction is correctly reflected in the employee's Form 16

So what happens if you miss a deadline? The consequences aren't pleasant. You'll face interest at 1% per month on the delayed TDS deposit. Plus, penalties can range from Rs. 10,000 to Rs. 1 lakh depending on the violation.

Form 16: What It Is and Why You Need It

Form 16 is your employer's certificate of TDS deducted. It's a two-part document. Part A contains your personal details and TDS information. Part B contains a detailed breakup of your salary and deductions.

And honestly, you can't file your income tax return without it. Well, technically you can, but it's not advisable. Form 16 serves as proof of income and TDS deduction, which the income tax department cross-checks with your return.

Your employer must issue Form 16 by June 30 following the end of the financial year. For the 2025-26 financial year, you should get it by June 30, 2026. If you don't receive it by then, follow up with your HR department.

Once you have Form 16, use it to file your income tax return. The TDS amount shown in Form 16 will be automatically credited against your tax liability. If you've been over-deducted, you'll get a refund.

TDS on Arrears, Bonuses, and Variable Components

When you get a bonus or arrears (back pay), how's TDS calculated? The rules are pretty clear but often misunderstood.

For arrears and bonuses, TDS is deducted in the month they're paid, not the month they were earned. Your employer calculates the tax on your total income (including the bonus or arrear) for the financial year and adjusts the TDS accordingly.

Here's where it gets tricky. If you receive a large bonus, it might push you into a higher tax bracket. Your employer will deduct TDS at the higher rate on that bonus. But don't worry—when you file your return, the tax is calculated on your total income for the year, and you might get a refund if you've been over-deducted.

• Bonuses are treated as salary for TDS purposes
• Arrears are deducted at the rate applicable in the month of payment
• Gratuity is deducted at a flat 30% (if it exceeds the exemption limit)
• Variable pay components are included in salary for TDS calculation
• Your employer should adjust TDS if your annual income estimate changes

TDS Deposit Deadlines and Penalties

This is where many employers slip up. The deadline to deposit TDS is the 7th of the following month. So TDS deducted in January must be deposited by February 7.

But if you're depositing via challan (not online), you get until the 10th. Still, most employers use online banking or the GST portal for TDS deposit, so the 7th deadline applies.

Miss this deadline, and you're liable for interest at 1% per month on the delayed amount. That's 12% per year. Plus, you might face penalties under Section 271B (up to Rs. 10,000) or even criminal prosecution in cases of deliberate non-compliance.

Quarterly TDS Returns and Filing

Employers with TDS liability must file quarterly TDS returns (also called quarterly TDS statement or QUARTERLY TDS RETURN). This is separate from depositing the TDS amount itself.

The return is filed in three parts. Part A contains TDS deducted on salary. Part B contains TDS on other payments (if any). Part C is a summary. You file it online through the income tax e-filing portal.

Deadlines for quarterly returns are roughly the 15th of the month following the end of each quarter. So for Q1 (April-June), you file by mid-August. For Q2 (July-September), by mid-November, and so on.

Missing these deadlines invites penalties and can trigger income tax department inquiries. So it's really important to keep track of these dates.

Special Cases and Exceptions

Some situations have special TDS rules. Let me walk you through the main ones.

If you're a resident but working abroad and earning foreign income, TDS rules still apply to your Indian salary. Similarly, if you're a non-resident Indian (NRI) working in India, TDS is deducted at a flat 30% on your salary (unless you file Form 12BB claiming exemption).

For employees of foreign companies working in India, TDS is deducted at the normal rates applicable to residents. If the foreign company doesn't have a permanent establishment in India, special rules might apply, but TDS is still deducted.

• NRI working in India: TDS at 30% unless exemption is claimed
• Resident working abroad: TDS on Indian salary as per normal rules
• Employees on contract: TDS deducted if they're classified as employees
• Contractual workers: TDS at 30% if no PAN is provided
• Religious institutions: Special exemptions may apply

How to Claim TDS Refund

If more TDS was deducted than your actual tax liability, you're entitled to a refund. But you need to file your income tax return to claim it.

The process is straightforward. When you file your return, you declare your total income, claim deductions and exemptions, and calculate your tax liability. If the TDS shown in Form 16 is higher than this liability, the difference is your refund.

The refund is usually processed within 3-6 months after you file your return, though it can sometimes take longer. You can track your refund status on the income tax e-filing portal.

One important point: if you're eligible for exemption from TDS (because your income is below the exemption limit), claim it by filing Form 12BB. Don't wait for a refund—it's better to avoid over-deduction in the first place.

Common Mistakes and How to Avoid Them

I've seen plenty of TDS mistakes over my years in practice. Let me share the most common ones so you can avoid them.

Mistake 1: Not submitting Form 12BB. Employees often skip this, thinking it's not important. Then they get over-deducted and wait months for a refund. Don't do that.

Mistake 2: Employers using outdated tax tables. Tax tables change every year. Using last year's tables can lead to incorrect TDS deduction and compliance issues.

Mistake 3: Not adjusting TDS for variable income. If your salary varies (due to bonuses, commissions, etc.), your TDS should be adjusted accordingly. Many employers don't do this.

Mistake 4: Missing TDS deposit deadlines. It's easy to forget, but the consequences are serious. Set reminders for the 7th of every month.

Mistake 5: Incorrect Form 16 issuance. Some employers issue Form 16 with wrong TDS amounts or late. This creates problems for employees during tax filing.

• Always submit Form 12BB if your income is below the exemption limit
• Keep copies of all TDS-related documents for your records
• Verify TDS deduction in your salary slip every month
• Report discrepancies to your HR department immediately
• File your income tax return on time to claim refunds quickly
• For employers: Use updated tax tables and maintain proper TDS records

Frequently Asked Questions

Q1: What's the difference between TDS and income tax?

A: TDS is tax deducted at the source (by your employer) and deposited with the government. Income tax is your total tax liability based on your annual income. TDS is basically an advance payment toward your income tax. If TDS deducted equals your total tax liability, you don't owe anything extra. If TDS is more, you get a refund. If it's less, you pay the difference.

Q2: Can I claim exemption from TDS if I have multiple employers?

A: Yes, but you need to be careful. You can claim exemption from one employer if your combined income from all employers is below the exemption limit. But you must inform both employers about this. It's best to claim exemption from your primary employer and let the secondary employer deduct TDS normally. Then claim a refund during tax filing.

Q3: What happens if my employer doesn't deduct TDS?

A: You're still liable for income tax on your salary. When you file your return, you'll need to pay the tax (plus interest and penalties) even if it wasn't deducted. Your employer, meanwhile, faces penalties and interest for not deducting TDS. So it's in both your interests to ensure TDS is deducted correctly.

Q4: Can I revise my Form 12BB during the year?

A: Absolutely. If your income estimate changes (say you expect a promotion or a bonus), you can submit a revised Form 12BB to your employer. They'll then adjust your TDS deduction for the remaining months. This helps you avoid over-deduction.

Q5: When should I expect my TDS refund?

A: After you file your income tax return, the refund is usually processed within 3-6 months. But it can sometimes take longer, especially if the income tax department needs to verify your return. You can check the status on the income tax e-filing portal using your acknowledgment number.

Q6: Is TDS deducted on gratuity?

A: Yes, but only if it exceeds the exemption limit. Gratuity up to Rs. 20 lakh is exempt from tax. Beyond that, TDS is deducted at a flat 30%. Your employer should handle this deduction when gratuity is paid.

Key Takeaways for 2026

TDS on salary is a critical compliance requirement for both employers and employees. Getting it right saves time, money, and stress. Here's what you need to remember:

• TDS is deducted based on tax slabs and the employee's expected annual income
• File Form 12BB if your income is below the exemption limit to claim exemption from TDS
• Employers must deposit TDS by the 7th of the following month
• Form 16 must be issued by June 30 following the financial year end
• If over-deducted, you can claim a refund by filing your income tax return
• Employers face serious penalties for non-compliance, so maintain proper records
• Always verify TDS deduction in your salary slip and report discrepancies

Conclusion

TDS on salary is straightforward once you understand the basics. Employees need to know their exemption limits and submit Form 12BB to avoid over-deduction. Employers need to deduct at the right rates, deposit on time, and issue Form 16 correctly.

The rules for 2026 remain largely consistent with previous years, but it's always good to check the income tax department's official website for any updates. If you're unsure about your TDS liability or compliance requirements, it's worth consulting with a tax professional. The cost of professional advice is often much less than the penalties and interest you might face for non-compliance.

Remember, TDS is not something to ignore or take lightly. It directly impacts your salary and your tax liability. Stay informed, keep proper records, and ensure compliance. That's the best approach.
