Second proviso to s.32(1) of the Income-tax Act, 1961 (s.33(4) of the 2025 Act): an asset bought in the year and put to use for less than 180 days gets half the rate. For FY 2025-26 the line falls between 3 and 4 October 2025. Fictional company and figures.

Why the chart takes days
Tally holds every entry. It does not hold the tax chart.
The asset ledgers, the purchase dates, the sale and the year-end journal are all in your books. What Tally does not do is group them into blocks, split the additions at the 180-day line, and give you the written-down value for tax — so the chart is made by hand, every audit, for every company.
xls
Built again in Excel, every year
Export the asset ledgers, sort each entry into its block, type in last year’s closing WDV, add it all up — and start again when one entry changes.
180
One day, half the rate
A ₹12,00,000 factory extension put to use on 4-Oct-2025 gets ₹60,000. On 3-Oct-2025 it would get ₹1,20,000. Count the day wrongly and the chart is wrong.
jv
The depreciation journal read as a sale
The year-end journal credits the asset ledger. A chart that treats every credit as a sale cuts the block a second time — so people set those vouchers to Optional and hope nothing else moved.
26
Form 26 is next
From tax year 2026-27 the tax audit report is Form No. 26. Its clause 36 takes over from clause 18: the same block-wise chart, with additions for 180 days or more and under 180 days in separate columns.
What the law asks for
Depreciation for tax is worked out on the block of assets — one class of asset at one rate — not asset by asset: the opening written-down value, plus the year’s additions, less the money received on assets sold, at the Appendix I rate. Additions put to use for less than 180 days in the year get half the rate.
The tax auditor reports it block by block: Form 3CD clause 18 for FY 2025-26, and Form No. 26 clause 36 from tax year 2026-27.

Open it, and the chart is already there.
One row per block — the figures for Form 3CD clause 18. Under it, a check that proves every entry on the asset ledgers was read, to the paisa.

The 180-day split, entry by entry
Every addition is dated and placed: for FY 2025-26, full rate up to 3-Oct-2025 and half rate from 4-Oct-2025. The day count can be switched on Alt+U to match your working.

Blocks assigned for you
Each asset ledger is placed in a block from its Tally group, else its name. Those rows stay light green until you confirm them — one by one with Ctrl+Enter, or many at once on Alt+J.
Alt+L
Asset by asset
Each ledger’s own opening, additions, sales, depreciation and closing WDV, under its block. Enter on a row opens its entries and the rate each one takes.
Alt+R
The additions table
Every addition of the year with its date, value, rate, depreciation, voucher number and supplier — the list the auditor asks for, ready for Excel.

Sales and capital gains
The money received on a sale reduces the block. If it is more than the block, or the block ends, the short-term capital gain or loss is worked out block by block.
Act
1961 or 2025, by period
FY 2025-26 prints the 1961 Act sections and Form 3CD clause 18. From tax year 2026-27 it prints section 33 of the 2025 Act and Form 26 clause 36.

The voucher date stands in until you type the real one. Alt+U on an asset’s entries: the 180-day split and the Companies Act days both follow it, and the voucher is not changed.

On Alt+W, type a ledger’s original cost and depreciation stops at the residual: 5% of cost unless you type another. Type the date first used and that ledger moves to straight-line.

Your books are not altered: the journal stays exactly as posted, and nothing is set to Optional. The chart simply does not count it as a sale — and the completeness check counts it on its own line.
Companies Act working · Alt+W
And the books side: Schedule II, day by day.
A company’s books follow the Companies Act, not the tax blocks. Alt+W gives the written-down-value working under Schedule II, pro rata by days: each ledger takes the rate for its nature (Part C), the opening balance counts for every day of the year, and each addition or sale counts from its own date.
The rate1 − 0.051 / useful lifethe written-down-value rate that leaves 5% of cost at the end of the useful life — 63.16% for 3 years, 18.10% for 15
The nature is guessed from the ledger’s group, shown light green until you confirm it, and saved on the ledger. The depreciation already booked is set against the working, so the difference is on the screen, not in a separate file.
Know the cost of an asset? Type it on the ledger (Ctrl+Enter) and depreciation stops at the residual value, 5% of cost unless you type another, or nil for intangibles and leasehold land. Type the date first used as well and that ledger moves to straight-line: its value less the residual, over the years left, with no catch-up.

Common questions
Which TallyPrime versions does it work on?
It is built and tested on TallyPrime 7.1. If you are on an earlier release, tell us which one on the form — we will tell you plainly whether it has been tried there before you rely on it.
Can I try it on a copy of my company first?
Yes — and please do, the first time. Take a backup, restore it as a copy, and load the add-on there. Compare its chart with last year’s working before you use it on the live company. Everything it does works the same on a copy.
Does it change my vouchers?
No. It posts no voucher and changes no entry, and you never have to set a depreciation journal to Optional. The only thing it saves is what you type and accept with Ctrl+A — a ledger’s block, and if you type them, its opening tax WDV, part-use share, unit, Companies Act nature, cost, residual, life, a split or a date put to use — and that is stored on the asset ledger itself, never on a voucher. The depreciation journal comes out as a file, only if you ask for it, and reaches your books only if you import it yourself.
Where does the opening tax WDV come from?
Tally holds book values, not tax values. Type each block’s opening tax WDV once, on any one ledger of the block (Ctrl+Enter), from last year’s Form 3CD clause 18 or the return’s depreciation schedule. Until you do, the report uses the book opening and shows it in red, so it is never mistaken for the tax figure.
How is the 180-day line counted?
The voucher date stands in for the date the asset was put to use, unless you type the real date on that entry (Alt+U on the asset’s entries). For FY 2025-26, an addition dated up to 3-Oct-2025 gets the full rate and one from 4-Oct-2025 gets half, counting the day of use. If your working does not count that day, switch it on Alt+U. An asset bought in an earlier year and first used this year takes the full rate — check anything moved out of work-in-progress.
Can it pass the depreciation journal for me?
No, on purpose: it posts nothing. It gives you the journal on screen, ledger by ledger, and writes it as a file if you ask. You check it, then bring it in with Tally’s own Import (Alt+O > Transactions), first on a copy of the company. The income-tax file needs a whole tax year, and a block with a sale stays out of it: book that block by hand. The Companies Act file can be for any month end and is marked WORKING, because useful lives, residual values and components can differ in the audit.
Are there any limits on the amounts?
Two, both set by the size of number Tally can hold. On the Companies Act working, one ledger above about ₹265 crore (higher at the lower rates: about ₹1,390 crore at 18.10%). And a voucher with several unequal asset lines above about ₹90 crore a line. Check those by hand. A smaller point: type a unit or branch name with no extra spaces, because a space before or after the name gives a second line of the same name. The block total stays right; retype the name to join them.
What happens when an asset is sold?
The money received or receivable on the sale voucher reduces the block — not the book value credited to the ledger. If it is more than the block, or the block ends with value left, the short-term capital gain or loss is worked out for that block.
1961 Act or 2025 Act?
It follows the period you set on F2. FY 2025-26 prints the Income-tax Act, 1961 sections and Form 3CD clause 18. From tax year 2026-27 it prints section 33 of the Income-tax Act, 2025 and Form No. 26 clause 36.
Is it advice?
No. It is a working aid that applies stated rules to your own data and shows the basis for each one on Alt+H, with links to the Income-tax site. Check every figure before it goes into the tax audit report.
Does my data leave my computer?
No. It runs inside your own TallyPrime on your own company data. Nothing is uploaded to us or to anyone else.
Is it really free? What’s the catch?
No catch — no licence fee, no trial clock, no activation key. We ask for your email so we can send the file, check in once to ask if it worked, and tell you if an update ships. We build these because they bring the right people to Chartford.
