8. Both-regime deductions

80CCD(2) — employer NPS cap

Table value: private_pct_basic_da: 14, central_govt_pct_basic_da: 14.

Source quote (cleartax §80CCD): "Employer's NPS contributions up to 14% (10% under the old regime) of salary can be claimed as a deduction" — i.e. private-sector cap is 14% only under the new regime; old regime stays 10%.

The schema has a single private_pct_basic_da field that doesn't distinguish regime. The table sets it to 14, which matches new-regime behaviour but overstates the old-regime cap.

Reference: https://cleartax.in/s/section-80ccd, Finance Act 2024 changes (effective FY 2025-26).

Verdict: ⚠ schema-level ambiguity — value is correct for new regime; old-regime private-sector cap remains 10%. The cell's notes ("Private-sector cap raised from 10% to 14% from AY 2025-26 onward") elides the regime split and is misleading. Mode 1 computations that pick the 14% value for an old-regime old-private-sector salaried user would over-deduct.

80CCH — Agniveer Corpus Fund

limit_paise: null, uncapped: true. ✅ on value (no statutory cap). Note caveat: only government's contribution (80CCH(2)) is deductible in new regime; self-contribution (80CCH(1)) only in old regime. The current notes ("Agniveer Corpus Fund self-contribution") doesn't flag the new-regime carve-out. ⚠ note-only.

80JJAA

additional_employee_cost_pct: 30, years_eligible: 3. Source: ClearTax/Tax2win §80JJAA — "30% of the additional employee cost as a deduction for three straight assessment years". ✅

9. Capital gains rules

asset_class	Cell content	Source check	Verdict
listed_equity_pre_23_jul_2024	LTCG 12mo, 10%, ₹1L exempt; STCG 15%	§112A/§111A pre Finance (No.2) Act 2024	✅
listed_equity_post_23_jul_2024	LTCG 12mo, 12.5%, ₹1.25L exempt; STCG 20%	"increased from 10% to 12.50%"; "₹1.25 lakh"; "rate for short-term... increased from 15 to 20%" (PIB/ClearTax §112A)	✅
debt_mf_on/after_2023-04-01	always slab; no LTCG concept	Finance Act 2023 §50AA	✅
debt_mf_pre_2023-04-01_pre_23_jul_2024	LTCG 36mo, 20% with indexation	Standard §112 with indexation	✅
debt_mf_pre_2023-04-01_post_23_jul_2024	LTCG 36mo, 12.5% without indexation	Finance (No.2) Act 2024	✅
unlisted/property_pre_23_jul_2024	LTCG 24mo, 20% with indexation	§112 (pre-amendment)	✅
unlisted/property_post_23_jul_2024	LTCG 24mo, 12.5%; "grandfathered_residents" indexation	Finance (No.2) Act 2024 with the 23 Jul 2024 land/building grandfather carve-out for resident individuals	✅
sovereign_gold_bonds_at_maturity	exempt	§47(viic) exemption at maturity	✅

Verdict: ✅ verified. Framework continues Budget-2024-July changes unchanged through Finance Act 2025.

10. Settlement cycle

settlement_cycle_days: 1 (T+1).

Source: SEBI — "T+1... by the end of January 2023"; T+0 is optional/beta in parallel, not the default. Citi/SEBI confirm T+1 remains the default settlement cycle through FY 2025-26. (https://www.sebi.gov.in/legal/circulars/mar-2024/...)

Verdict: ✅ verified. The inline comment "T+1 since 27 Jan 2023" is the right anchor.

Note: the prompt mentioned "T+0 phased complete" — at AY 2026-27 the optional T+0 cycle is being phased in; it does not replace T+1. Default for capital-gains-day-count purposes remains T+1. The cell is correct.

11. NPS Tier-1 returns

Field	Table value	Source quote	Verdict
scheme_e_cagr_pct_range	[10, 13]	"equity component (Scheme E) has delivered 10–13% CAGR over a decade" (paisabazaar/HDFC Securities)	✅
scheme_g_cagr_pct_range	[8, 9]	Recent 3-yr ~9%, 5-yr ~7.2-7.5%; decade-window 8–9% is in the right band but the lower end is generous	⚠
blended_cagr_pct_range	[9, 12]	"NPS Tier 1 accounts offer returns ranging from 9% to 12% CAGR"	✅
decade_window	"2016-2025 decade (PFRDA-published)"	Aligns with publicly cited PFRDA decade data	✅

Verdict: ⚠ Scheme G lower bound — recent 5-yr returns are 7.2–7.5%, but the decade window (which includes the higher-rate years 2016-2020) could plausibly average to 8%. Not a hard error for V1 projection ranges; flag for CA review.

12. HRA metros

["Mumbai", "Delhi", "Kolkata", "Chennai"] — statutory metros for §10(13A) 50% calculation.

Source: "The original 4 metros (Delhi, Mumbai, Chennai, Kolkata) have had a 50% of salary HRA limit since 1961. New metros from April 1, 2026 being Bengaluru, Pune, Hyderabad, and Ahmedabad" (mstock.com).

The new four metros apply from FY 2026-27 (AY 2027-28) — NOT AY 2026-27. For AY 2026-27 (FY 2025-26), the four-city list is correct.

Verdict: ✅ verified for AY 2026-27. Note for future: the AY 2027-28 table will need the expanded 8-city list if the April-2026 expansion is gazetted by then.

---

13. Sources block

URLs cite ClearTax, Tax2win, Bajaj Finserv, PFRDA, NPS Trust, IT Dept salaried-individuals page, paisabazaar, HDFC Securities. The IT Dept link is the closest to a primary source. All non-government URLs are reputable secondary references that cite Finance Act 2025.

Gap: no direct citation to Finance Act 2025 Gazette PDF (egazette.gov.in) or the IT Dept tutorial PDF (incometaxindia.gov.in/Tutorials/2 Tax Rates.pdf, which currently 403's via WebFetch but is a known primary). Adding one primary citation would strengthen the sources block, but is not a value discrepancy.

Verdict: ✅ acceptable for verified status; primary-source augmentation recommended.

Summary

Verified: 60+ cells (slabs ×11, std-ded ×2, 87A ×6, surcharge ×11, cess ×1, old-regime deductions ×27, both-regime ×4, capital gains ×8 rules, settlement, HRA, NPS, sources). Discrepancies (hard): 0. Caveats / ⚠: 3 (80CCD(2) old vs new regime split not modelled; 80CCH new-regime carve-out not in notes; NPS Scheme G lower bound generous for trailing-5-year window). Unavailable: 0.

Top issues for CA review

1. 80CCD(2) private-sector cap — schema only stores one private_pct_basic_da value; the table sets it to 14%, which is the new-regime cap. The old-regime cap for private-sector employees remains 10% per Finance Act 2024 / cleartax. Either (a) extend the schema to model old_regime_pct / new_regime_pct separately, or (b) document that Mode 1 must hard-code old-regime private to 10% downstream and revise the notes to flag the split. Functional risk: old-regime private-sector salaried users would be over-deducted at 14%.

2. 80CCH Agniveer notes — the notes say "Agniveer Corpus Fund self-contribution" but elide that under new regime only the government's §80CCH(2) contribution is deductible; self-contribution (§80CCH(1)) is old-regime-only. Narrow-impact (V1 wedge), but worth a line in notes.

3. NPS Scheme G lower bound — [8, 9] is defensible for the 2016-2025 decade window but recent trailing 5-year returns are ~7.2-7.5%. For projection UX, consider widening to [7, 9] or adding a "trailing-window" variant. Cosmetic for V1.

Recommended verdict

Flip back to draft with pending_reason noting the 80CCD(2) regime-split modelling gap as the blocking item for CA sign-off.

Rationale: the four critical Budget-2025 cells (new-regime slabs, ₹60k 87A, ₹12L 87A ceiling, ₹75k std ded) are all correct, and the capital-gains/surcharge/cess/old-regime grid is all correct. The single substantive issue is the 80CCD(2) cell carrying the new-regime 14% value without a regime-split — this is a Mode 1 over-deduction risk for any old-regime private-sector salaried user, which is exactly the user cohort V1 has to compute correctly today.

If a CA confirms that Mode 1 downstream already hard-codes 10% for old-regime private-sector NPS-employer matching and only reads 14% from this cell for new-regime, keep verified and amend the cell notes to document that contract. Otherwise the table cannot honestly be marked verified for old-regime computations.

The two other ⚠ items (80CCH notes, NPS Scheme G range) are not blockers and can be addressed in the same draft → verified round-trip.
