Assumptions & limits (v0.1)
- Methods: s19A(1) three-year write-off · s19A(2) one-year write-off for computers and prescribed automation equipment · s19A(10A) low-value assets (cost ≤ S$5,000 each, aggregate S$30,000 per YA) · s19 with 20% initial allowance and straight-line annual allowances over a 6, 12 or 16-year working life · the accelerated 75%/25% two-year option.
- Classification engine: pasted descriptions are auto-classified — computers and prescribed automation to the 1-year write-off, S-plate private cars and land/buildings flagged as non-qualifying, renovation-type lines cross-flagged to the s14N tool. Suggestions only; every method stays editable.
- Accelerated 75%/25%: announced Budget-by-Budget (YA 2021 through YA 2026 to date) — confirm the option is available for your YA before claiming. No deferral is permitted under this option.
- Assumed: full cash purchase in the acquisition basis period (hire-purchase instalment claims are not modelled); allowances claimed every YA without deferral; s19 initial allowance claimed in the acquisition YA.
- Disposals: no allowance in the YA of disposal; balancing allowance = TWDV less proceeds, balancing charge = proceeds (capped at cost) less TWDV, capped at total allowances claimed. No balancing adjustment is computed where no allowances were ever claimed. Section 24 related-party elections are not modelled.
- Qualifying plant only: enter qualifying plant & machinery — S-plate private cars do not qualify.
- Everything runs client-side. Assets are saved in this browser only (localStorage) — use CSV to keep a copy.
- This is a workpaper aid, not advice — review the output against the Income Tax Act 1947 and current IRAS guidance before filing. See the site terms.
