Tax deducted at source on salary is not random, it is your employer’s best guess of full-year tax spread across months. When income jumps or declarations change, TDS can spike suddenly. Understanding the projection helps you plan cash flow and avoid arguing with payroll over arithmetic that is actually correct.
- Employers project full-year income and tax, then adjust monthly TDS to catch up.
- Bonus and arrears months often show higher TDS because the annual picture jumped overnight.
- Regime selection with payroll must align with what you will claim at filing (subject to rules).
- Always verify TDS credits in Form 26AS, not only on payslips.
Payroll systems start with declared exemptions, deductions, and regime, then annualise salary. Each month they recompute remaining tax divided by remaining months.
If you earn nothing extra, TDS is fairly flat. If November brings a six-figure bonus, November and December TDS may both rise because the system must still collect full-year tax by March.
Old regime projections include 80C-style declarations you gave in April; new regime projections exclude many of them. Switching declarations mid-year without updating proofs changes the trajectory.
Your final regime on the ITR must follow law for that year; if it differs from payroll’s assumption, you may owe more or claim refund via return, but 26AS will still show what was deducted.
Payslips show month-wise deduction; Form 26AS shows what reached the government against your PAN. If Part A of Form 16 and 26AS disagree, escalate to HR and TRACES processes early.
Waiting until July to discover missing TDS credit delays refunds and creates needless anxiety.
SalTax writes for salaried taxpayers and professionals in India who want clear explanations, not jargon. Our guides reflect how tax compliance works in practice, including payroll, Form 16, AIS, and filing, but they are educational only. They are not tax, legal, or investment advice. Rules, limits, and forms change with each Finance Act and assessment year. Always confirm the current year on the official Income Tax Department website (incometax.gov.in) and use a Chartered Accountant or qualified tax adviser for your own return, notices, or planning.
