72## Section 2 -- Required inputs and refusal catalogue
73 
74### Required inputs
75 
76Before computing any advance tax figure, you MUST know:
77 
781. Age as of April 1 of the assessment year -- senior citizen exemption may apply
792. Nature of income -- business/profession, capital gains, salary, rental, other sources
803. Has the client opted for presumptive taxation (s. 44AD / 44ADA)? -- changes the instalment schedule
814. Estimated total income for the financial year -- needed to compute estimated tax liability
825. Tax regime chosen: old or new (s. 115BAC)? -- affects tax rates and available deductions
836. TDS already deducted or expected during the year -- reduces advance tax obligation
847. TCS credits available -- also reduces advance tax obligation
858. Any brought-forward losses or unabsorbed depreciation? -- affects taxable income estimate
86 
87If estimated total tax liability after TDS/TCS is less than Rs. 10,000, STOP. No advance tax is due.
88 
89### Refusal catalogue
90 
91**R-IN-AT-1 -- International income with DTAA credit timing.** Trigger: client has income from multiple countries and asks about advance tax credit for foreign taxes under a Double Tax Avoidance Agreement. Message: "DTAA credit timing in advance tax computation is complex and outside this skill's scope. Please escalate to a Chartered Accountant with international tax expertise."
92 
93**R-IN-AT-2 -- Reassessment interest disputes.** Trigger: client is disputing interest levied under s. 234B or s. 234C following a reassessment. Message: "Interest disputes under reassessment proceedings require representation before the assessing officer. This is outside this skill's scope. Please escalate to a Chartered Accountant."
94 
95**R-IN-AT-3 -- Income-tax Act, 2025 transitional queries spanning both regimes.** Trigger: client asks about advance tax provisions that span both the 1961 Act and the 2025 Act. Message: "The Income-tax Act, 2025 (effective 1 April 2026) replaces ss. 234B/234C with new sections 424/425. For FY 2025-26, the 1961 Act applies. Queries spanning both regimes should be escalated to a Chartered Accountant."

135## Section 4 -- Advance tax computation rules
136 
137### 4.1 Who must pay advance tax (Tier 1)
138 
139Legislation: Income-tax Act, 1961, s. 207, s. 208
140 
141| Category | Advance Tax Required? |
142|---|---|
143| Self-employed with estimated tax liability >= Rs. 10,000 | YES |
144| Salaried with other income and estimated tax >= Rs. 10,000 | YES |
145| Senior citizen (60+) with NO business/professional income | NO (exempt under s. 207) |
146| Senior citizen (60+) WITH business/professional income | YES |
147| Presumptive assessee (s. 44AD / 44ADA) | YES, but single instalment |
148| Any person with estimated tax liability < Rs. 10,000 | NO |
149 
150Threshold calculation:
151 
152```
153estimated_tax_liability = tax_on_estimated_total_income + surcharge + cess
154net_advance_tax_due = estimated_tax_liability - TDS_credits - TCS_credits
155if net_advance_tax_due < 10,000:
156 advance_tax_required = NO
157else:
158 advance_tax_required = YES
159```
160 
161The Rs. 10,000 threshold is on the NET tax after TDS/TCS credits, not gross tax.
162 
163### 4.2 Interest under s. 234B -- default in payment (Tier 1)
164 
165Legislation: Income-tax Act, 1961, s. 234B
166 
167Section 234B applies when total advance tax paid is less than 90% of assessed tax.
168 
169```
170if advance_tax_paid < (assessed_tax x 90%):
171 shortfall = assessed_tax - advance_tax_paid
172 interest_234B = shortfall x 1% x number_of_months
173```
174 
175Rate: 1% per month or part of month (simple interest). Period: from 1 April of assessment year to date of self-assessment tax payment or regular assessment. Any part of a month counts as a full month.
176 
177### 4.3 Interest under s. 234C -- deferment of instalments (Tier 1)
178 
179Legislation: Income-tax Act, 1961, s. 234C
180 
181Interest is triggered when advance tax paid by the due date is less than the shortfall trigger percentage:
182 
183| Due Date | Shortfall Trigger | Interest Period |
184|---|---|---|
185| 15 June | Paid less than 12% of assessed tax | 3 months |
186| 15 September | Paid less than 36% of assessed tax | 3 months |
187| 15 December | Paid less than 75% of assessed tax | 3 months |
188| 15 March | Paid less than 100% of assessed tax | 1 month |
189 
190The shortfall triggers (12%, 36%) include an 80% tolerance on the cumulative targets (15% x 80% = 12%, 45% x 80% = 36%), except December (75% actual) and March (100% actual).
191 
192```
193# June instalment
194if paid_by_jun15 < (assessed_tax x 12%):
195 shortfall = (assessed_tax x 15%) - paid_by_jun15
196 interest = shortfall x 1% x 3
197 
198# September instalment
199if paid_by_sep15 < (assessed_tax x 36%):
200 shortfall = (assessed_tax x 45%) - paid_by_sep15
201 interest = shortfall x 1% x 3
202 
203# December instalment
204if paid_by_dec15 < (assessed_tax x 75%):
205 shortfall = (assessed_tax x 75%) - paid_by_dec15
206 interest = shortfall x 1% x 3
207 
208# March instalment
209if paid_by_mar15 < (assessed_tax x 100%):
210 shortfall = (assessed_tax x 100%) - paid_by_mar15
211 interest = shortfall x 1% x 1
212```
213 
214For presumptive assessees: only one instalment by 15 March, only 1 month interest if short. No June/September/December shortfall applies.
215 
216Capital gains / lottery exemption: if a shortfall is caused by capital gains, lottery, or first-time business income, the shortfall is ignored for s. 234C provided the assessee pays in remaining instalments or by 31 March.
217 
218### 4.4 Interaction with TDS credits (Tier 1)
219 
220Legislation: Income-tax Act, 1961, s. 190, s. 199, s. 209
221 
222TDS already deducted reduces estimated tax liability before computing advance tax instalments. TDS is treated as advance tax paid on the date it was deducted (for s. 234C) or as reduction from assessed tax (for s. 234B). Self-assessment tax (s. 140A) is NOT counted as advance tax for interest calculation.
223 
224### 4.5 New tax regime interaction (Tier 1)
225 
226Legislation: Income-tax Act, 1961, s. 115BAC
227 
228The regime choice (old vs new) affects the estimated tax liability and therefore the advance tax quantum. It does NOT change the instalment schedule or interest provisions.
229

259 
260## Section 6 -- Senior citizen exemption and penalties
261 
262### 6.1 Senior citizen exemption (Tier 1)
263 
264Legislation: Income-tax Act, 1961, s. 207, proviso
265 
266| Condition | Advance Tax Obligation |
267|---|---|
268| Resident individual 60+ with NO business/professional income | EXEMPT |
269| Resident individual 60+ WITH business/professional income | NOT exempt -- must pay |
270| Non-resident senior citizen | NOT exempt -- must pay |
271 
272If exempt, no interest under s. 234B or s. 234C applies.
273 
274### 6.2 Penalties (Tier 1)
275 
276| Penalty Type | Rate | Legislation |
277|---|---|---|
278| Interest on total default (s. 234B) | 1% per month (simple) on shortfall | s. 234B |
279| Interest on instalment deferment (s. 234C) | 1% per month (simple) on instalment shortfall | s. 234C |
280| Penalty for non-payment of demand | Up to amount of tax in arrears | s. 221 (discretionary) |
281 
282Interest under s. 234B and s. 234C can both apply simultaneously. Interest is mandatory and non-discretionary -- the Assessing Officer has no power to waive or reduce it.
283 
284---
285 
286## Section 7 -- Edge case registry
287 
288### EC1 -- Income primarily from capital gains, unforeseeable (Tier 1)
289Situation: Client earns most income from capital gains realised in January. No advance tax paid in June or September.
290Resolution: Capital gains exemption under s. 234C applies. No interest on June/September shortfall caused by capital gains income. Client must pay advance tax on capital gains in December or March instalment. s. 234B may still apply if total advance tax is short by year-end.
291 
292### EC2 -- TDS covers most of the liability (Tier 1)
293Situation: Client is a consultant with Rs. 15,00,000 income. TDS at 10% = Rs. 1,50,000. Estimated total tax = Rs. 1,80,000. Net advance tax = Rs. 30,000.
294Resolution: Advance tax required (Rs. 30,000 > Rs. 10,000). Pay in four instalments. TDS credit reduces the base for interest computation.
295 
296### EC3 -- Presumptive assessee who also has capital gains (Tier 2)
297Situation: Client uses s. 44AD for business income but also has capital gains.
298Resolution: Presumptive instalment rule (single payment by 15 March) applies to the business income portion. Capital gains portion may require separate advance tax in the instalment following realisation. Flag for reviewer.
299 
300### EC4 -- Senior citizen with rental and business income (Tier 1)
301Situation: Client aged 65, has rental income of Rs. 6,00,000 and freelance consulting income of Rs. 2,00,000.
302Resolution: Senior citizen exemption does NOT apply because the client has business/professional income. Full advance tax schedule applies on all income.
303 
304### EC5 -- Revised income estimate mid-year (Tier 1)
305Situation: Client's income estimate increases significantly after September.
306Resolution: Recalculate and pay the shortfall in December and March instalments. s. 234C interest applies only to the extent of shortfall at each instalment date based on final assessed tax.
307 
308### EC6 -- Advance tax paid but ITR not filed (Tier 2)
309Situation: Client paid all advance tax instalments but did not file ITR by the due date.
310Resolution: s. 234B interest does not apply (advance tax was paid). However, s. 234A interest (late filing) applies separately at 1% per month. Flag for reviewer.
311 
312### EC7 -- NRI with Indian business income (Tier 2)
313Situation: Non-resident Indian with business income from India through a fixed place of business.
314Resolution: Advance tax provisions apply to NRIs. The senior citizen exemption does NOT apply to non-residents. Flag for reviewer -- confirm DTAA relief availability.
315 
316### EC8 -- Transition to Income-tax Act, 2025 (Tier 2)
317Situation: Client asks about advance tax provisions under the new Income-tax Act, 2025.
318Resolution: The Income-tax Act, 2025 (effective 1 April 2026) replaces ss. 234B/234C with new sections 424/425. For FY 2025-26 (AY 2026-27), the 1961 Act still applies. Flag for reviewer.

350## Section 9 -- Test suite
351 
352### Test 1 -- Standard self-employed, four instalments
353Input: Age 40, estimated total income Rs. 12,00,000 (business), new tax regime, no TDS, no presumptive scheme.
354Expected output: Tax approx Rs. 1,17,000 (after rebate/cess). Advance tax: Rs. 17,550 by Jun 15, Rs. 52,650 cumulative by Sep 15, Rs. 87,750 cumulative by Dec 15, Rs. 1,17,000 by Mar 15.
355 
356### Test 2 -- Below threshold
357Input: Age 35, estimated total income Rs. 8,00,000 (business), new tax regime, TDS of Rs. 25,000.
358Expected output: Tax approx Rs. 32,500. Net after TDS = Rs. 7,500. Below Rs. 10,000 threshold. NO advance tax required.
359 
360### Test 3 -- Presumptive taxation (s. 44AD)
361Input: Age 45, business turnover Rs. 1,50,00,000, presumptive income at 8% = Rs. 12,00,000, no TDS.
362Expected output: Single instalment of 100% advance tax due by 15 March. No June/September/December obligations.
363 
364### Test 4 -- Senior citizen exempt
365Input: Age 67, resident, income from house property Rs. 5,00,000 + interest Rs. 3,00,000. NO business income.
366Expected output: Senior citizen exemption applies. NO advance tax required.
367 
368### Test 5 -- Senior citizen NOT exempt (has business income)
369Input: Age 65, resident, freelance income Rs. 10,00,000. Tax liability above Rs. 10,000.
370Expected output: Exemption does NOT apply. Full four-instalment schedule required.
371 
372### Test 6 -- s. 234B interest calculation
373Input: Assessed tax Rs. 5,00,000. Total advance tax paid Rs. 3,00,000. Self-assessment tax paid on July 25 of AY.
374Expected output: Shortfall = Rs. 2,00,000. 90% threshold = Rs. 4,50,000. Advance tax paid < 90%, so s. 234B applies. Interest = Rs. 2,00,000 x 1% x 4 months (Apr, May, Jun, Jul) = Rs. 8,000.
375 
376### Test 7 -- s. 234C interest on missed June instalment
377Input: Assessed tax Rs. 4,00,000. Paid Rs. 0 by Jun 15. Paid Rs. 1,80,000 by Sep 15.
378Expected output: Jun shortfall trigger: 12% of Rs. 4,00,000 = Rs. 48,000. Paid Rs. 0 < Rs. 48,000. Interest base = (15% x Rs. 4,00,000) - Rs. 0 = Rs. 60,000. Interest = Rs. 60,000 x 1% x 3 = Rs. 1,800.
379 
380### Test 8 -- TDS covers liability
381Input: Consultant income Rs. 20,00,000. TDS at 10% = Rs. 2,00,000. Estimated tax = Rs. 2,10,000. Net = Rs. 10,000.
382Expected output: Net advance tax exactly Rs. 10,000. At threshold -- s. 208 says "exceeds Rs. 10,000", so at exactly Rs. 10,000, NO advance tax required.

386## Section 10 -- Prohibitions and disclaimer
387 
388### Prohibitions
389 
390- NEVER compute advance tax without confirming estimated total income and applicable tax regime
391- NEVER ignore the Rs. 10,000 threshold -- always check net tax after TDS/TCS before prescribing advance tax
392- NEVER apply the senior citizen exemption to a client with business/professional income
393- NEVER apply the senior citizen exemption to non-resident individuals
394- NEVER tell a presumptive assessee they must pay four instalments -- single instalment by 15 March applies
395- NEVER compute s. 234B interest using gross tax -- always reduce by TDS/TCS credits first
396- NEVER waive or suggest waiver of s. 234B/234C interest -- it is mandatory and non-discretionary
397- NEVER conflate self-assessment tax (s. 140A) with advance tax -- they are separate for interest computation
398- NEVER forget that s. 234B and s. 234C can BOTH apply simultaneously to the same assessee
399- NEVER present advance tax figures as definitive -- always label as estimated and advise the client to consult their CA for final computation
