Changed jobs during the year, or worked with two employers? Each employer deducts TDS as if theirs is your only salary – the standard deduction is applied twice, the Section 87A rebate can be applied twice, and the second salary restarts at the 0 percent slab. The result: your Form 16s look fully paid, but a large tax shortfall (plus interest) surfaces when you file. This calculator consolidates multiple Form 16s the way the Income-tax Act requires, shows exactly where the gap comes from, and computes what you must pay before filing. It also plans the correct monthly TDS for your new employer if you submit Form 12B.
Step 1 – Enter details from EACH Form 16 (Part B)
Use the GROSS salary (row 1 of Part B) – NOT the final income figure, because that already has each employer’s own standard deduction inside it (that is the trap). Split the row-2 exempt allowances into the two boxes: items exempt in BOTH regimes (gratuity 10(10), leave encashment 10(10AA), commuted pension, VRS, official-duty allowances) vs items exempt ONLY in the OLD regime (HRA, LTA, children education allowance, food coupons). TDS figure comes from Part A.

Step 2 – Other income and deductions (optional)
House property loss: OLD regime allows set-off up to Rs 2,00,000 against salary (balance carries forward). NEW regime does not allow set-off of HP loss (and self-occupied interest is not deductible). Positive rental income is taxable in both.

Multiple Form 16 – Frequently Asked Questions
How do I file ITR with two Form 16s?
Add the GROSS salary and exempt allowances from each Form 16 Part B, claim the standard deduction only once on the total, claim professional tax actually deducted by both, and claim TDS credit from both Part As (verify against Form 26AS/AIS). This calculator gives you the consolidated figures to enter in your return. Usually ITR-1 still applies if your other conditions fit – check our ITR form selector.
Why do I suddenly owe tax when both employers deducted TDS correctly?
Each employer computed TDS as if theirs was your only salary: standard deduction applied twice, the Section 87A rebate possibly applied twice, and your second salary started again at the lowest slabs. On aggregation the income moves into higher slabs and the rebate may vanish – creating a shortfall that neither Form 16 shows.
Is the standard deduction Rs 75,000 per employer?
No. It is one deduction per taxpayer per year against total salary income – Rs 75,000 in the new regime, Rs 50,000 in the old – even if you had four employers.
What is Form 12B and is it compulsory?
Form 12B (Rule 26A) is the statement of previous-employer salary and TDS that you MAY give your new employer under section 192(2). It is optional – but if you skip it, the new employer cannot consider your earlier salary and you will almost certainly face a year-end shortfall with interest.
What is the difference between Form 12B and Form 12BA?
Form 12B is given BY the employee to a new employer with previous salary details. Form 12BA is given BY the employer to the employee – it is the perquisite statement that accompanies Form 16 for salaries above Rs 1,50,000.
I worked two jobs at the same time (moonlighting). How is TDS handled?
Under section 192(2) you choose ONE employer and give it Form 12B with the other salary details; that employer deducts on the aggregate. Both salaries are fully taxable and both appear in your AIS, so consolidation at filing is unavoidable. Dual employment may also raise contractual and PF questions outside tax law.
Will interest apply on my shortfall?
Possibly both 234B and 234C. 234B applies at 1 percent per month from April of the assessment year if your TDS covered less than 90 percent of the assessed tax and the shortfall is Rs 10,000 or more. 234C applies on advance-tax instalment shortfalls during the year itself. Pay self-assessment tax as early as possible to stop 234B from growing monthly.
Can I claim relief under section 89(1) for this?
No. Section 89(1) relief is for arrears or advance of salary that belong to other years. Salary from two employers in the SAME year is normal current-year income – it is aggregated, not relieved.
Both employers deducted professional tax. Can I claim both?
Yes – section 16(iii) allows the professional tax actually paid (old regime only). The Rs 2,500 constitutional ceiling is on what one state can levy; if both employers deducted in the same state and the total exceeded Rs 2,500, the excess is a refund matter with the PT department, not an income-tax adjustment.
Both my employers paid gratuity or leave encashment exemption. Anything to watch?
Yes – the exemption ceilings (gratuity Rs 20 lakh, leave encashment Rs 25 lakh, VRS Rs 5 lakh) are aggregate or lifetime limits, not per-employer. If both Form 16s claim these exemptions, total them against the cap in your return.
My previous employer refuses to give Form 16. What do I do?
Download Form 26AS and AIS from the e-filing portal – the salary paid and TDS deducted appear there. Use your salary slips for the gross and exemption break-up. TDS credit is available on the 26AS figures even without the certificate.
What is the due date for AY 2026-27?
For ITR-1 and ITR-2: 31 July 2026. For ITR-3 and ITR-4 without audit: 31 August 2026. Belated returns until 31 December 2026 (with late fee u/s 234F), and revised returns until 31 March 2027.
Which regime applies when I had two employers with different regime choices for TDS?
The TDS-time choice does not bind your return. You pick the regime in the ITR itself (salaried taxpayers can switch each year). This calculator compares both regimes on the consolidated income and shows which is better.
Does this calculator work for FY 2026-27 too?
Yes for planning – the slabs, rebate and standard deduction are unchanged for FY 2026-27, and from 1 April 2026 the Income-tax Act 2025 renumbers sections without changing these rates. Use the Form 12B tab if you changed jobs in the current year.
