TaxMarg vs ChatGPT: We Asked Both the Same 5 Tax Questions

We asked both TaxMarg and ChatGPT (GPT-4) the same 5 tax questions that CAs commonly research. Here is what each tool returned, unedited.

Question 1: "What is the TDS rate under Section 194C of the IT Act?"

ChatGPT's answer:

"Under Section 194C of the Income Tax Act, 1961, TDS on payments to contractors is deducted at 1% for payments to individuals/HUFs and 2% for payments to other entities. The threshold is Rs. 30,000 for a single payment and Rs. 1,00,000 for aggregate payments during the financial year."

TaxMarg's answer:

"Section 194C of the IT Act 1961 (now Section 393 of the IT Act 2025) provides for TDS on payments to contractors at the following rates:

• 1% for payments to individuals or HUFs
• 2% for payments to any other person (company, firm, etc.)

Threshold: No TDS if the single payment does not exceed Rs. 30,000 AND total payments during the tax year do not exceed Rs. 1,00,000 [Section 393(5), IT Act 2025].

Note: With effect from AY 2026-27, the relevant section is 393 of the IT Act 2025. Section 194C of the 1961 Act continues to apply for assessment years up to AY 2025-26."

Verdict: ChatGPT gave the correct rate but cited only the old Act without noting the 2025 Act transition. TaxMarg cited both Acts with the exact new section number and the threshold sub-section.

Question 2: "Compare old vs new tax regime for a salaried person earning Rs. 18 lakh"

ChatGPT's answer:

"For FY 2025-26, under the new regime: Income up to 3L: nil, 3-7L: 5%, 7-10L: 10%, 10-12L: 15%, 12-15L: 20%, above 15L: 30%. Standard deduction of 75,000. Tax would be approximately Rs. 1,95,000. Under old regime with 80C (1.5L), 80D (25K), HRA (2.4L): Tax would be approximately Rs. 1,56,000. Old regime is better if you have total deductions above Rs. 3.75 lakh."

TaxMarg's answer:

"For AY 2026-27 (Tax Year 2025-26), comparison for gross salary of Rs. 18,00,000:

New Regime [Section 200, IT Act 2025]:

• Standard deduction: Rs. 75,000 [Section 22(2)]
• Taxable income: Rs. 17,25,000
• Tax: Rs. 1,95,000
• Less: Rebate u/s 87A: Nil (income exceeds Rs. 12,00,000)
• Add: Cess 4%: Rs. 7,800
• Total tax: Rs. 2,02,800

Old Regime [Section 199, IT Act 2025]:

Assuming deductions: 80C Rs. 1,50,000 + 80D Rs. 25,000 + HRA Rs. 2,40,000 + standard deduction Rs. 50,000

• Taxable income: Rs. 13,35,000
• Tax: Rs. 1,86,500
• Add: Cess 4%: Rs. 7,460
• Total tax: Rs. 1,93,960

Break-even: Old regime is beneficial when total deductions (80C + 80D + HRA + others) exceed approximately Rs. 3,75,000.

Cross-reference: Old regime Section 115BAC proviso of IT Act 1961 corresponds to Section 199 of IT Act 2025."

Verdict: ChatGPT gave approximate numbers without cess and without section citations. TaxMarg gave exact calculations with cess, cited every provision, and showed the old-to-new section mapping.

Question 3: "What is the time limit for reassessment under the new Act?"

ChatGPT's answer:

"Under the new provisions, reassessment can be initiated within 3 years from the end of the assessment year if income escaping assessment is Rs. 50 lakh or less, and within 10 years if it exceeds Rs. 50 lakh. Prior approval of specified authority is required."

TaxMarg's answer:

"Under Section 280 of the IT Act 2025 (corresponding to Section 149 of the IT Act 1961):

Time limits for issuing notice under Section 279 (old Section 148):

• Within 3 years from end of relevant AY: For any amount of escaped income [Section 280(1)(a)]
• Beyond 3 years but within 5 years: Only if escaped income is Rs. 50 lakh or more [Section 280(1)(b)]
• Beyond 5 years but within 10 years: Only if escaped income is Rs. 50 lakh or more AND represented as asset [Section 280(1)(c)]

Mandatory prerequisite: Before issuing notice under Section 279, the AO must conduct inquiry under Section 279A (old Section 148A) and provide the assessee an opportunity of being heard [Section 279A(2)].

Approval required:

• Up to 3 years: Joint Commissioner [Section 280(2)(a)]
• Beyond 3 years: Principal Chief Commissioner or Principal Commissioner [Section 280(2)(b)]

Ref: CBDT Circular No. 1/2026 dated 15.01.2026 clarifies that the new time limits apply to notices issued after 01.04.2026."

Verdict: ChatGPT gave a simplified version with only two time brackets. TaxMarg provided all three time brackets with the asset condition, the mandatory 279A inquiry requirement, approval hierarchy, and the relevant CBDT circular. The ChatGPT answer could mislead a CA into thinking 10-year reassessment is possible for any amount above Rs. 50 lakh, when in fact it requires the income to be represented as an asset.

Question 4: "How to calculate HRA exemption?"

ChatGPT's answer:

"HRA exemption under Section 10(13A) is the minimum of: (a) Actual HRA received, (b) 50% of salary for metro cities or 40% for non-metro, (c) Rent paid minus 10% of salary. Salary means basic + DA."

TaxMarg's answer:

"HRA exemption under Section 17 of the IT Act 2025 (old Section 10(13A) read with Rule 2A of IT Rules 1962, now Rule [X] of IT Rules 2026) is the least of:

1. Actual HRA received from employer

2. 50% of salary if residence is in Mumbai, Delhi, Chennai, or Kolkata; 40% of salary for all other cities [Section 17(1)(b)]

3. Actual rent paid minus 10% of salary [Section 17(1)(c)]

Salary for this purpose means basic salary + dearness allowance (if forming part of retirement benefits) + commission based on fixed percentage of turnover. It does NOT include other allowances, perquisites, or bonus.

Example: Basic salary Rs. 60,000/month, HRA Rs. 25,000/month, rent paid Rs. 20,000/month (Mumbai):

• Actual HRA: Rs. 3,00,000/year
• 50% of salary: Rs. 3,60,000/year
• Rent minus 10% salary: Rs. 2,40,000 - Rs. 72,000 = Rs. 1,68,000/year
• Exemption: Rs. 1,68,000 (least of the three)

Note: HRA exemption is only available under the old tax regime. Under the new regime (Section 200, IT Act 2025), HRA is fully taxable."

Verdict: ChatGPT gave the formula correctly but did not specify which components are included in "salary," did not provide the new Act section, and critically missed the new-regime exclusion. TaxMarg provided the complete formula, salary definition, a worked example, and the regime applicability note.

Question 5: "Is GST ITC available on food and beverages?"

ChatGPT's answer:

"No, ITC is blocked on food and beverages under Section 17(5)(b) of the CGST Act. However, ITC is available if the food is provided to employees as per any statutory obligation, or if the food and beverages are used for making an outward taxable supply of the same category."

TaxMarg's answer:

"Input Tax Credit on food and beverages is blocked under Section 17(5)(b)(i) of the CGST Act, 2017, with the following exceptions:

Blocked: ITC on food and beverages, outdoor catering, beauty treatment, health services, cosmetic and plastic surgery, UNLESS:

1. Inward supply used for outward supply of same category: If you are in the restaurant/catering business and purchase food ingredients, ITC is available [Section 17(5)(b)(i) proviso]

2. Statutory obligation: If providing food to employees is mandated by any law (e.g., Factories Act requirement for canteen in factories with 250+ workers), ITC is available [Section 17(5)(b)(ii)]

3. Employee perquisite as per employment contract: Blocked. ITC is NOT available on food provided as a perk, even if part of CTC

GST Council clarification: Circular No. 172/04/2022-GST dated 06.07.2022 clarifies that ITC on canteen services is available only when it is obligatory under the Factories Act, 1948 (Section 46) or any other law. Voluntary canteen facilities do not qualify.

Relevant case law: The Maharashtra AAR in the case of Tata Motors (2019) held that ITC on canteen services is available proportionate to the employer's cost where Factories Act mandates the canteen."

Verdict: ChatGPT gave a correct but incomplete answer. TaxMarg provided the exact section with sub-clause reference, all three exception scenarios, the relevant GST circular, and a supporting AAR ruling. The distinction between statutory obligation and voluntary provision is critical and was missed by ChatGPT.

The Pattern

Across all 5 questions, the pattern is consistent:

ChatGPT is a good starting point for general understanding. TaxMarg is built for professional research where precision and citations matter.
