Getting a new job mid-year is an exciting milestone. You negotiated a better salary. But then July rolls around, you sit down to file your income tax return, and you are hit with an unexpected tax demand.
If your first thought is, “Wait, is the government taxing me twice?”. It is one of the most common tax-season panics for salaried professionals.
To understand why you suddenly owe money, you have to look at it from your employers’ perspectives. When you switch jobs, your old company and your new company do not communicate with each other.
Because of this, both HR departments calculate your monthly Tax Deducted at Source (TDS) assuming they are your only employer for the entire financial year. They both give you the full benefit of basic tax exemptions and lower tax slabs, which ultimately leads to your taxes being under-deducted throughout the year.
This lack of coordination creates two specific traps:
Trap 1: The Double Deduction: Every salaried employee gets a flat Rs 75,000 standard deduction to lower their taxable income. But you are only legally allowed to claim this discount once per year. Because they didn’t know about each other, both of your employers likely subtracted Rs 75,000 when estimating your taxes. When you finally file your return, the system catches the duplicate, removes one, and suddenly taxes you on that missing amount.
Trap 2: The Section 87A Illusion: If you are filing under the new tax regime for FY 2025-26, your total income is below Rs 12,00,000, the government offers a Section 87A rebate that brings your tax down to zero.
Imagine you earned Rs 6,00,000 at your old job and Rs 7,50,000 at the new one. Employer A sees your 6 Lakh salary, applies the rebate, and deducts zero TDS. Employer B sees your 7.5 Lakh salary, applies the same rebate, and also deducts zero TDS.
But when you sit down to file and combine those two salaries, you actually made Rs 13,50,000. Because you crossed that 12 Lakh threshold, you no longer qualify for the rebate.
How to Fix it?
- Gather Your Paperwork: Get both Form 16s in front of you.
- Verify the Government’s Records: Log into the income tax portal and check your Annual Information Statement (AIS) and Form 26AS. You want to make sure the TDS deducted by both companies matches what the government actually received.
- Do the Math carefully: Add your gross salaries together, but make absolutely sure to subtract the standard deduction only once. If you are using the old tax regime, the same rule applies to deductions like Section 80C, 80D, and HRA—claim them just once.
- Settle the Balance: Since your tax was under-deducted, you will likely have a shortfall. You need to pay this as a “self-assessment tax” before you can finish filing.
The Golden Rule for Your Next Job Switch
To avoid the July tax shock next time you change jobs, hand your new employer a Form 12B as soon as you join. This simple form declares your previous earnings, allowing your new finance team to accurately deduct TDS on your combined income from day one.
