Changed Jobs Mid-Year? Form 16 (Now Form 130), Two Employers, and Filing Your Tax Correctly

If you changed jobs partway through the financial year, the most common tax surprise is this: both employers deducted TDS as if they were your only employer, and when you add the two salaries together in your return, there is extra tax to pay. It is not a penalty and nobody made a mistake. Each employer simply calculated tax on the slice of salary it knew about.

The fix is to report both salaries correctly, check the TDS on each, and pay any shortfall before you file. Better still, tell your new employer about the old salary as soon as you join, so the gap never builds up in the first place.

A quick note on form names, because they just changed

The Income-tax Act, 2025 replaced the 1961 Act from 1 April 2026, and the Income-tax Rules, 2026 renumbered most forms. For salaried people, the ones that matter:

• Form 16, the salary TDS certificate from your employer, is renumbered Form 130 for tax year 2026-27 onwards.
• Form 12B, used to tell a new employer your previous salary and TDS, has been merged with Form 12BAA into Form 122.
• Form 12BB, the investment and deduction declaration to your employer, becomes Form 124.

If you are filing the return for FY 2025-26, meaning income earned April 2025 to March 2026, you are still dealing with the old forms: a Form 16 from each employer. If you switched jobs during the current tax year, 2026-27, your new employer should be using Form 122 for your previous-employer details, and your certificates next year will be Form 130. Some payroll systems take time to catch up, so don't be alarmed if HR still says "12B" in conversation.

Right after you join: tell your new employer about the old salary

This is the step that prevents most of the pain. Give your new employer's payroll the salary paid and TDS deducted by your previous employer so far this year, using Form 122 (previously Form 12B). The Income Tax Department's FAQ on Form 122 describes it as the way to report salary from other employers so the current employer can deduct the right amount of TDS. It is not something you upload to the government. It goes to the employer.

Once they have it, the new employer can calculate TDS on your combined income for the year and spread any extra over your remaining months. Some people skip this because it slightly reduces their take-home for the rest of the year. That's fair, but then expect to pay the difference yourself at filing time.

Your final payslip and full-and-final statement from the old employer usually have the year-to-date salary and TDS figures you need.

Why the shortfall happens

Without that information, each employer assumes your annual income is only what it pays you. So each one applies the lower slabs on its own and, under whichever regime it assumed, may apply the standard deduction and even the rebate as if yours was a smaller income. Put the two together and your total income sits in a higher bracket than either employer allowed for. Your two employers might even have assumed different tax regimes if you gave them different declarations.

At filing time: what to actually do

1. Collect a salary TDS certificate from each employer: Form 16 for FY 2025-26, and Form 130 from tax year 2026-27. Ask the old employer early. They issue it after the year closes, and ex-employees sometimes get forgotten.
2. Check your AIS and Form 26AS on the income tax e-filing portal. Both employers' TDS should appear against your PAN. If one is missing or the amount differs from the certificate, contact that employer's payroll. They may have filed their TDS return incorrectly, and only they can revise it.
3. Report salary from both employers in your return. ITR forms have space for multiple employers. Don't just add up the "taxable salary" figures from two certificates without checking. Look at what each one has already subtracted.
4. Claim the standard deduction only once. If both certificates show it, you still get it only once on your total salary. The same goes for other deductions: a limit such as the old-regime section 80C cap applies to you for the year, not per employer.
5. Pick your regime deliberately. According to the department's salaried individuals page, the new regime is the default, and people without business income can opt in or out each year directly in the return, filed by the due date. What you told your employers for TDS doesn't lock you in.
6. Pay any shortfall as self-assessment tax before you submit the return. The portal's e-pay tax option handles this. If the gap is large, interest can apply, which is another reason to report the old salary to the new employer during the year.

A few situations that trip people up

A gap between jobs. Months with no salary don't cause any problem. Just report what each employer paid.

Leave encashment, notice-pay recovery or a joining bonus. These appear in your salary figures and can be taxed differently depending on the component and your regime. Check how each employer's certificate shows them, and ask a tax professional if the amounts are significant.

PF. Transferring your PF to the new employer isn't a taxable event. Withdrawing it can be, depending on your years of continuous service. If you're tempted to withdraw during the switch, read our PF transfer guide first.

HRA and rent. Under the old regime, HRA exemption depends on the months you actually received HRA and paid rent. If you moved cities between jobs, keep rent receipts for both places.

Keep a small folder

For each employer, keep the offer letter, the last payslip or F&F statement, and the TDS certificate. Add your Form 122 copy for the new employer, AIS screenshots and your self-assessment tax challan. It feels like overkill until you get a notice or a refund query two years later.

If you're still comparing offers and want to understand how CTC turns into monthly take-home, including how the tax regime changes the value of each component, see CTC vs in-hand salary.

This is general guidance based on the Income Tax Department's published material as of September 2026, not tax advice. Rules, due dates and forms can change. Check the e-filing portal and consult a chartered accountant for your specific situation.
