Form No. 122 (Earlier Form No. 12B) - Change of Employment
Switched jobs mid-year? This is the one form that keeps your new employer's TDS calculation accurate - and the one most people forget to hand over.
When you move employers within the same financial year, your new employer has no visibility into what you earned - or what was already deducted - at your previous job. Form 122 closes that gap.
What is Form 122?
Form 122 is a document that captures your income and the tax already deducted by your previous employer in the current financial year. If you change jobs mid-year, submitting it to your new employer is mandatory. It gives them the information they need to calculate your correct tax liability and deduct the right amount of TDS from your salary going forward.
Why It Matters
Accurate Tax Calculation
Your new employer factors in income from your previous job, so TDS is computed on your actual combined salary - not just what they're paying you.
Avoiding Interest
Without Form 122, the new employer may under-deduct tax. That shortfall surfaces later as additional tax plus interest when you file your return.
Filing Your ITR With Multiple Form 16s, If You Skipped Form 122
If Form 122 wasn't submitted at the time and you now hold multiple Form 16s for the year, filing your return takes a slightly different path:
Combine income. Aggregate the total income earned from every employer during the financial year.
Consolidate TDS. Add up the TDS amounts shown across all your Form 16s.
Pay the differential tax, if any. Once income and TDS are reconciled, settle whatever tax shortfall remains before filing.
If you've recently changed jobs and aren't sure whether your current TDS deduction reflects your full-year income correctly, our Taxation team can review your Form 16s and flag any shortfall before it becomes a notice.
