Left one job and joined another mid-year? Upload both Form 16s β no typing numbers. AI reads them, combines your income across both employers, and tells you exactly what you owe or what's owed to you.
When you switch jobs between April and March, you get two Form 16s β one from each employer. Each employer calculates TDS only on the salary they paid you, applying the full slab benefit and standard deduction as if that was your only income for the year. Neither employer knows what the other paid you unless you submit Form 12B to your new employer.
If you got a hike when you switched β common when moving jobs is a 20-40% salary bump β your combined annual income can push you into a higher tax slab than either employer individually accounted for. The result: you're under-deducted through the year, and the shortfall shows up as a demand when you file your ITR, sometimes with interest under Section 234B/234C for not paying advance tax on time.
Manually copying figures off a Form 16 is easy to get wrong β people mix up gross salary with taxable salary, or miss which TDS row is the final total. This tool reads your actual Form 16 PDFs directly and extracts the numbers for you, so the reconciliation is based on what your employers actually reported, not a guess.
