CA Final IDT Important Questions with Solutions

Working through CA Final IDT important questions with solutions helps bridge this gap. It highlights high-weightage areas, clarifies tricky provisions, and builds the analytical skills needed to perform well in the exam.

Essential Concepts from CA Final IDT Important Questions

Regularly practising CA Final IDT important questions strengthens conceptual understanding. Here are examples of types of questions you may encounter:

1. Sequencing decides time-of-supply and interest questions

Time of supply (goods/services) is the earliest of invoice date, payment date, or provision date; never assume "advance payment always wins." Interest under Sec 18 (provisional assessment) runs from the month of provisional assessment, not the reassessment date. Refund interest (Sec 56) can have two separate legs, general 6% and appellate-refund 9%; don't merge or skip either. Always draw the timeline before applying the rule.

2. RCM applies well beyond the classic memorised list

GTA (if not opted for forward charge, recipient must be "specified"; includes Sec 51-registered govt bodies), legal services to a business entity, metal scrap from unregistered persons (separate notification), and even split/outsourced export contracts (the outsourced slice becomes a deemed import under RCM). Check: is it notified, does the recipient qualify, has the supplier exercised any override option?

3. Thresholds apply per unit, not in aggregate

RWA's Rs. 7,500 exemption is per member per flat — a member with 6 flats gets it 6 times over, not once. Once a single flat crosses Rs. 7,500, the whole amount is taxable (not just the excess). TDS of Rs. 2.5 lakh threshold applies per contract, not per period total to a recipient. Always find the law's stated unit before adding numbers together.

4. "Before vs. after a cutoff" flips the answer

Remission of duty: allowed only if goods are lost/destroyed before clearance for home consumption. Vouchers: taxed at issue if the supply is identifiable, at redemption if not. ITC on works contract: blocked for immovable property generally, but allowed for "plant & machinery" (fixed to earth, used in the supply chain). Job work: inputs must return within 1 year, capital goods within 3 years, but moulds/dies/tools are exempt from this limit entirely.

5. Export/import has specific carve-outs beyond the basic definition

Related-party services can still count as export if FEMA-compliant payment is received. Split-payment export contracts (part paid to a foreign sub-supplier with RBI's permission) still count as full export, while also triggering RCM on the outsourced slice. DHSP-to-foreign-CCSP hosting and India-based clinical trials both qualify as export via specific circulars, not the plain definition. Intangible goods like online money gaming get their own IGST-levy route, separate from both goods and services import rules.

6. Appeal forum and pre-deposit depend on what the dispute is about

If the case involves rate of tax or place of supply, appeal from the Tribunal skips the High Court and goes straight to the Supreme Court. Pre-deposit is two separate stages: 10% of disputed tax at the first appellate authority, another 10% (of the amount then confirmed) at the Tribunal; each capped, and computed excluding interest/penalty. Check what the SCN was substantively about before assuming the standard appeal ladder.
