New Income Tax Rules 2026: Every Change That Affects Your Salary, HRA & TDS

Let me be direct with you.

April 1, 2026 is not just the start of a new financial year. It is the day India's entire income tax rulebook changes.

The government has replaced the Income-tax Rules, 1962 rules that were 64 years old with brand new Income Tax Rules, 2026. And these rules come into force today, alongside the Income-tax Act, 2025.

If you are a salaried employee, a business owner, a freelancer, a CA, or even a student who just started earning this change affects you directly.

I am going to break every single important change down, in plain language, so that whether you are filing your own ITR for the first time or you are a seasoned tax professional, you walk away knowing exactly what changed and what you need to do.

First, Understand What Actually Changed (And What Did Not)

Before I get into the specifics, let me clear one big fear: the government did not introduce any new tax.
The official transition FAQ from CBDT is clear (Central Board of Direct Taxes) the new law is not creating a new tax burden. It is a structural and drafting simplification. Think of it like this: the old rulebook had 511 rules written across decades in complicated legal language. The new rulebook has 333 rules, written more clearly, with tables and formulas replacing long paragraphs.

Here is the size of the change at a glance:

The government cut forms from 399 to 190 nearly half. That alone tells you this was a massive housekeeping exercise, not a new tax grab.

Change 1: Your Allowances Are Finally Updated for 2026

This is the change that will matter most to salaried employees, and honestly, it is long overdue.

Many of the allowance limits in India's tax rules were set decades ago and had never been revised. The exemption for children's education allowance, for example, was ₹100 per month per child. Yes, ₹100. In 2026.

The new rules fix this. Here is every major allowance change:

What this means for you practically:

If your employer gives you a children's education allowance, you were getting a tax-free benefit of ₹1,200 per year per child (₹100 × 12). Now that jumps to ₹36,000 per year per child (₹3,000 × 12). That is 30 times more. If you have two kids, that is ₹72,000 of tax-free income annually.

The hostel allowance went from ₹3,600/year per child to ₹1,08,000/year. These are not small changes.

Important: These enhanced exemptions are available only under the Old Tax Regime. If you are on the new tax regime, these allowances do not apply to you.

This is actually a reason for many salaried employees to re-evaluate whether switching back to the old regime makes sense for them in FY 2026-27.

Change 2: PAN Rules What Transactions Need PAN Now

The government has updated the monetary limits for PAN quoting requirements. Some limits went up (good for you), and at least one went down (pay attention).

Notice that one line I marked with ⚠️. Cash withdrawal limit for mandatory PAN quoting has been cut from ₹20 lakh to ₹10 lakh. So if you withdraw large amounts of cash from your bank account, the threshold for PAN requirement is now stricter.

Everything else largely becomes more relaxed or is restructured logically.

Change 3: HRA 4 New Cities Get 50% Exemption

If you live in a rented house and claim HRA (House Rent Allowance), this change is directly relevant to you.

Currently, only four cities get the 50% HRA exemption:

• Mumbai

• Delhi

• Chennai

• Kolkata

The new rules add four more cities to this list:

• Bengaluru

• Pune

• Hyderabad

• Ahmedabad

So now 8 cities qualify for the 50% HRA exemption instead of 4.

This is significant because rent in Bengaluru and Hyderabad has been sky-high for years. A software engineer living in Koramangala or Gachibowli was getting 40% HRA exemption despite paying Mumbai-level rent. That injustice is corrected now.

How HRA exemption works (quick refresher):

HRA exemption = Lowest of these three:

1. Actual HRA received from employer

2. Actual rent paid minus 10% of basic salary

3. 50% of basic salary (for metro cities) OR 40% (for non-metro cities)

If you live in Bengaluru, Pune, Hyderabad, or Ahmedabad, point 3 now gives you 50% instead of 40%. That is a meaningful jump if your basic salary is high.

Again HRA exemption is only under the Old Tax Regime.

Change 4: Every Form You Know Is Getting Renamed

This is where things get a little confusing, and I want to make sure you do not mess this up.

The government has renumbered almost every income tax form. Your Form 16 is now Form 130. Form 15G and 15H are merging into a single Form 121 a new declaration form for nil TDS on interest, dividend, and rent income from April 2026. Form 26AS is becoming Form 168.

Here is the complete form mapping you need to bookmark:

TDS Return Forms

TDS Certificates

PAN, Declarations, and Other Key Forms

📋 Form 121 is already live.
Complete Form 121 guide eligibility income limit and how to submit →

The biggest simplification in this list: Tax audit previously you filed three separate forms (3CA, 3CB, 3CD). From Tax Year 2026-27 onwards, you file a single Form 26. CAs across India will save hours of work every audit season.

Change 5: The Critical Transition Which Period Uses Which Law?

This is the part most articles get wrong or skip entirely. I want you to understand this clearly.

The rule is simple:

• FY 2025-26 and all earlier years → Income-tax Act, 1961 + Rules, 1962 continue to apply

• Tax Year 2026-27 onwards → Income-tax Act, 2025 + Rules, 2026 apply

This means 2026 is a transition year where both laws exist simultaneously.

TDS Deposit Which Law Applies When?

For non-government deductors:

TDS Returns Critical Due Dates You Cannot Miss

Important: Correction statements for old quarters (FY 2025-26 or earlier) must still be filed under the 1961 Act framework. The new Act does not absorb old-period corrections.

Change 6: GST and TDS The Connection You Must Know

Since you are on SmartGST, let me explain one rule that directly connects your GST invoices to income tax TDS.

Under CBDT Circular No. 23/2017, when you raise an invoice for services and show GST separately, the TDS gets deducted only on the service value not on the GST amount.

Let me show you with a simple example:

This rule works only when three conditions are met:

1. The payment is to a resident

2. GST is on services

3. The GST amount is shown separately in the invoice or contract

This is not a new GST rule. It is not a new income tax rate. It is a CBDT clarification that GST collected on behalf of the government is not your income so TDS should not be deducted on it.

Practical impact: As a service provider, you receive less excess TDS deduction, which means better cash flow and fewer refund headaches. As a business making payments, you deduct TDS on a lower base, which is simpler and legally correct.

Make sure your GST invoices always show the service value and GST amount separately And before you make any payment to a vendor, always verify their GSTIN is active and genuine a fake GST number can cost you your entire ITC claim. If they do not, this benefit disappears and disputes can arise.

Change 7: Other Important Updates

Record-Keeping Goes Digital for Professionals

Under the new rules, professionals who were maintaining manual books must now maintain mandatory digital books of accounts. Manual registers are no longer acceptable.

Property SFT Limit Raised

The Statement of Financial Transactions (SFT) limit for property transactions increases from ₹30 lakh to ₹45 lakh. Transactions below this threshold do not need to be reported under SFT.

E-Rupee (Digital Rupee) Recognised

The CBDC ( Central Bank Digital Currency) India's digital rupee is now officially recognised as a valid electronic mode of payment under the income tax rules. This is a forward-looking change as the RBI continues to expand e-rupee usage.

Old Tax Regime vs New Tax Regime Should You Reconsider?

With the new allowance limits, the old tax regime becomes more attractive for a specific set of taxpayers.

The old regime makes sense if:

• You live in a rented house in any of the 8 HRA metro cities (especially now Bengaluru, Pune, Hyderabad, Ahmedabad)

• Your employer provides a company car

• You have children with education and hostel allowances from your employer

• You have home loan interest, Section 80C investments, medical insurance premiums

The new tax regime makes sense if:

• You have minimal deductions

• You prefer simplicity over maximum tax savings

• Your income is relatively low and the basic exemption and slabs in the new regime already give you a good deal

With the hostel allowance jumping from ₹300/month to ₹9,000/month per child, many parents in salaried jobs who had written off the old regime might find it is worth re-calculating.

I strongly recommend running a quick comparison before you submit your investment declarations to your employer this year.

What You Need to Do Right Now Action Checklist

If you are a salaried employee:

• Recalculate old regime vs new regime with updated allowance limits

• Check if you live in Bengaluru, Pune, Hyderabad, or Ahmedabad your HRA exemption just improved

• Update your investment declaration form with your employer for FY 2026-27

• Ensure your employer has your new PAN application form details if you ever apply for PAN afresh

If you are a business owner or freelancer:

• Ensure all GST invoices show service value and GST separately this protects your TDS treatment

• Update your accounting software to handle new form numbers

• File Q4 FY 2025-26 TDS returns by 31 May 2026 under old forms

• Start using new TDS return forms from April 2026 onwards

If you are a CA or tax professional:

• Map all your clients' old forms to new form numbers

• Set reminders for dual compliance during FY 2026-27 (both laws run simultaneously)

• Correct old period TDS returns only under the 1961 Act framework

• Prepare clients for the new Form 26 for tax audit in TY 2026-27

• Shift to digital books for professional clients who still use manual registers

The Bottom Line

The New Income Tax Rules 2026 do not increase your tax burden. What they do is bring long-overdue logic and clarity to a rulebook that was built in 1962 and patchworked ever since.

The allowance updates alone are a genuine relief for salaried India. The form consolidation saves time for professionals. The HRA expansion recognises that Bengaluru and Hyderabad are as expensive as Mumbai.

But the transition is going to be messy for a few months. Two laws running side by side, old forms for old periods, new forms for new periods it requires attention.

Stay organised. Keep your records clean. And when in doubt, use tools to check your GST compliance, ITC eligibility, and filing due dates because the last thing you want in a transition year is a penalty for something avoidable.
