Section 104 of the Income-tax Act, 2025 — Unexplained Asset (Money, Jewellery, Bullion & Virtual Digital Assets)

In plain language

What Section 104 actually says

Section 104 of the Income-tax Act, 2025 deals with the "unexplained asset." In plain words: if the tax authorities find that you own — or that there belongs to you — an asset such as money, bullion, jewellery, a virtual digital asset (crypto/NFT) or any other valuable article, and either (a) it is not recorded in your books of account, or (b) it is recorded but at a value lower than what you actually spent to acquire it, then the value (or the excess) can be treated as your income.

The section is triggered in a tax year when both these things are true:

• The asset (or the excess amount) is discovered and is not fully/correctly recorded in the books.
• You offer no explanation about the nature and source of how you got it, or the explanation you give is not satisfactory in the opinion of the Assessing Officer (AO).

When triggered, "the value of such asset, or such excess amount, as the case may be, shall be deemed to be the income of the assessee" for that financial year.

The key new phrase: "owned by OR belonging to"

This is the most important upgrade over the old law. The 1961 Act (Sections 69A/69B) used the word "owned." The 2025 Act deliberately says "owned by or belonging to" the assessee. This is a shift toward substance over form — the department can now tax assets held in someone else's name (a benami-style holding, a relative's locker, a nominee) if the asset in reality belongs to you. It also for the first time expressly names virtual digital assets (crypto, NFTs), reflecting modern reality.

Who it applies to

• Every category of taxpayer — individuals, HUFs, firms, LLPs, companies, AOPs. There is no exemption by status.
• It is used typically during assessment, search or survey, when the AO finds unaccounted gold, cash, crypto, cars, or a locker whose contents you cannot explain.
• It applies whether or not you maintain books — the "not recorded in books" test simply looks at whatever records exist.

How it is taxed — the sting is in Section 195

Income deemed under Section 104 does not get taxed at your normal slab. It is pooled with other "deemed income" provisions and taxed under Section 195 of the 2025 Act (the successor to Section 115BBE of the 1961 Act) at a special flat rate. As originally enacted this special rate was 60% (plus a 25% surcharge and cess) — an effective burden of roughly 78%. The Finance Act, 2026 is reported to reduce this base rate from 60% to 30% for income under Sections 102–106. You should confirm the exact final rate and surcharge for your assessment year, because this figure was still being finalised and the effective rate depends on how surcharge is applied.

• No deductions, no expenses, no allowances may be claimed against this income.
• No set-off of any loss is allowed against it.
• The basic exemption limit does not shelter it.

How Section 104 interacts with its siblings

Section 104 sits inside the "Aggregation of income" chapter alongside a family of anti-black-money provisions. Each one plugs a different gap: unexplained credits in the books, unexplained investments, unexplained assets, unexplained spending, and hundi transactions. The AO picks whichever fits the facts. All of them then feed into the single punitive rate under Section 195.

Practical implications

• Keep a clean paper trail for every high-value asset — gift deeds, bank statements, purchase invoices, crypto exchange statements.
• The burden of explanation is on you, not the department. A vague "it was savings" rarely passes.
• Because the rate is punitive and no set-off is allowed, a Section 104 addition is far costlier than normal-slab tax — plus penalty and possible prosecution.
• Assets in a spouse's or child's name that are really funded by you are now squarely within reach due to the "belonging to" language.
