Tax: the rules that nibble

Tax is a leak you can see. Learn the map. Do not treat this page as an ITR.

Tax law moves. This chapter is a map of *kinds*, not this year’s slabs.

Different pipes, different tax stories

  • Salary: tax at source, slabs, standard deduction, the usual April paperwork.
  • Interest from savings / FDs - usually taxed as income (details depend on the instrument).
  • Capital gains: when you sell an investment for more than you paid (with rules about cost, holding period, and type).
  • Dividends: taxed in the investor’s hands under current design; do not build a personality around last decade’s rule.

Equity-oriented and debt-oriented products have been given different holding-period stories over the years. Before you sell, read the *current* holding period and rate. Do not memorise a blog from 2019.

80C is a box, not a mall

Section 80C (and friends) cap how much of certain investments / expenses can lower taxable income. EPF, PPF, ELSS, life-premium in some shapes, tuition in some shapes - they compete inside a ceiling.

Buying a product *only* to fill 80C, when you already filled it with EPF, is how people lock money they did not need to lock.

ELSS is equity with a lock-in, sometimes used for that box. It is still equity. The lock-in is a feature and a constraint.

What 201 will not do

Compute your tax. File your return. Promise a refund. Name a “best ELSS.”

**Note:** Slabs, surcharge, holding periods, and 80C cousins change in budgets. Verify with a current official source or a qualified professional. Educational, not tax advice.

Where it breaks

Selling a long-term core in March for a tiny tax story. Filling 80C with a product whose lock-in fights a 2-year goal. Ignoring tax until the notice.

  • Know which pipe a rupee is in: salary, interest, gain.
  • 80C is a ceiling. Count EPF first.
  • Verify this year’s rule before you act.
