I declare presumptive income under Section 58 44AD/44ADA-type filers — the single-instalment rule of s.408(2) applies.

The rules, with their sections

Who pays: advance tax applies only when your tax for the year (after TDS) is ₹10,000 or more — s.404.
Normal schedule — s.408(1): cumulative 15% by 15 June, 45% by 15 September, 75% by 15 December, 100% by 15 March.
Presumptive shortcut — s.408(2): if you declare profits under s.58(2) Table Sl. 1 or 3 (the 44AD/44ADA tracks), you may pay the whole amount in one instalment by 15 March.
Interest for missing it — s.425: 1% per month (simple) for 3 months per deferred instalment, and 1 month for the 15 March one; s.424: 1% per month from 1 April if you've paid less than 90% of your assessed tax.
Tolerance — no s.425 interest on the June/September instalments if you've paid at least 12% by 15 June and 36% by 15 September.

Worked example

A presumptive freelancer expects ₹85,000 tax for tax year 2026-27. One instalment: ₹85,000 by 15 March 2027. Missing it costs 1% — ₹850 — under s.425, and continuing past 31 March without reaching 90% starts the s.424 meter at 1% per month. A non-presumptive consultant with the same ₹85,000 pays ₹12,750 by 15 June, ₹25,500 more by 15 September (₹38,250 total), ₹25,500 more by 15 December (₹63,750 total), and the last ₹21,250 by 15 March.

Edge cases to know

Capital gains or windfalls mid-year: instalments falling due before the gain arises aren't penalised — pay proportionately from the next instalment.
TDS counts: your "tax for the year" here is after TDS — many freelancers whose clients deduct 10% find they owe little or no advance tax.
Resident senior citizens (60+) without business income are exempt from advance tax under the old Act's s.207(2) — but presumptive filers by definition have business income, so this rarely helps here; ask a CA for the new-Act equivalent.
Paying late but within the year: everything paid by 31 March still counts as advance tax; interest stops accruing on what's paid.
