Welcome to the
Armoury.

Paste the P&L, balance sheet and fixed-asset register, confirm each classification, and get the complete Singapore corporate tax file — Statements A–D, every supporting schedule and the Form C / C-S filing summary — as a formatted Excel working paper. Closed beta; access is by request from the sign-in page.

• Full capital allowances — hire purchase, disposals and balancing adjustments, s.14N renovation, EIS — with per-asset schedules that tie to the dollar
• Handles the harder shapes: investment holding and dormant bases, FRS 116 leases, foreign income with FTC pooling and FSIE, non-SGD functional currencies
• Classifications run on the Russolutions rules engine, with your manual picks always kept

The personal return prepared the way a corporate file is: enter the IR8A line by line, build the Appendix 8A schedule, settle residency, claim the reliefs, and read one computation from gross salary to tax payable. Closed beta; access is by invitation.

• Full IR8A build-up — salary, bonus, allowances, gratuity, pensions, share gains and benefits-in-kind, with employment expenses deducted and capped
• Appendix 8A housing worked properly: annual value apportioned by days occupied and employees sharing, furnishing loaded on top, rent tested against it
• Reliefs from earned income to national service, with the S$80,000 cap shown as an add-back rather than a silent trim

The tax computation for a fund claiming exemption under sections 13D, 13O, 13OA or 13U: confirm which holdings are designated investments, link each income line to the holding behind it, and anything unlinked, unconfirmed or excluded falls to the taxable side. Closed beta; access is by invitation.

• Specified income tested properly — the designated-investment question and the four Fifth Schedule exclusions asked separately, and only where they can bite
• Common expenses apportioned by gross income share, with directly attributable and non-deductible items kept out of the pool and shown on their own schedule
• A computation, a Form C filing summary and a cover letter, emailed as a package — with the scheme’s qualifying conditions recorded alongside and sourced

Ask a Singapore tax question, get a point-form answer drawn only from official sources — IRAS pages, the statutes, CPF Board and MOM material — with the citation and its as-at date under every answer.

• Six personas focus the search: general, personal, corporate, GST, transfer pricing, international
• Every point cites its source — the page or section number, ready to verify in seconds
• If the official sources don’t cover it, no answer is offered rather than an unsourced one — and where they cover only part of it, the answer says which part they don’t

One case per client, per year, per work type — corporate income tax from the ECI through the Form C-S / C, personal income tax, ACRA annual returns, IRAS queries and ad-hoc engagements — each generating its stages and statutory dates from the client’s year end. Shared across your firm, with every change logged. Closed beta; access is by request from the sign-in page.

• A client-year view: each engagement rolls up per client and year, opening into its work-type cases with the current stage, chaser count and next deadline on every row
• Dates that follow the statutes — ECI within 3 months of year end, Form C-S / C by 30 November, Form B / B1 by 18 April, AGM at 6 months and the annual return at 7 months from FYE, and IRAS queries paced back from the reply-by date on the letter
• Two people can work the same case, offline if need be, and the case keeps a who-and-when trail instead of one silently overwriting the other — client names and UENs are encrypted in your browser before they are stored

File Form C-S from a finished return — upload the tax-return workbook the CIT calculator exports, paste the filing summary as text, or key the boxes directly. Every field is validated against the IRAS schema for the Year of Assessment before anything is sent. Direct filing with IRAS (Seamless Filing From Software) arrives with APEX onboarding; until then submissions run a clearly-labelled simulation. Closed beta; access is by request from the sign-in page.

• Reads the exported *_F-C.xlsx box-by-box — company particulars, YA, basis period and every mapped amount land in one drop, with the source of each figure tagged
• The full IRAS field schema (YA 2023–2026): types, lengths, accepted characters, conditional-mandatory rules and the cascade cross-checks, with IRAS’s own diagnostic wording on every issue
• The IRAS sandbox validation scripts load in one click, and each acknowledgement is compared against IRAS’s expected results — sandbox certification as a checklist, not a scramble

Turn a rough idea into a precise AI brief — Context, Role, Audience, Format, Task, Exclusions, Documentation — and copy the finished prompt straight out. Runs in your browser; no sign-in.

• Six builders in one: persona, search, new-topic, Humaniser, Council (a panel of advisers argues your decision) and an accounting mode that turns receipts, statements and invoices into fixed-column tables
• Set the seven CRAFTED fields once, with one-click tone, style and output-file chips
• New to prompting? A two-minute lesson sits one click away inside the tool

Paste an income statement and get a draft Singapore corporate tax (ECI) computation, return calculations and follow-up points — emailed to you after a quick verification.

• Reads untidy pastes — comparative columns, currency and basis period detected
• Guided questions only where they apply: interest, leases, provisions, asset claims
• The full computation engine runs server-side — nothing to install

Drop a General Ledger export — Xero Account Transactions, Xero GL Detail, MYOB GL, or most standard Excel formats — and get back a tax-ready workpaper in seconds. Upload and parse are free; a quick email verification unlocks the full analysis.

• Income statement and balance sheet reconstructed directly from the ledger
• Transactions distilled into patterns — typically 60–70% fewer lines to review
• High-risk items flagged with next-step prompts: entertainment, vehicles, renovation, WHT, capital items and more

A keyboard-first calculator mapped to the left side of the keyboard — Q W E for 7 8 9, A S D for 4 5 6, and so on — so your right hand never leaves the mouse.

• Audit-trail history with copy, round, delete, save to file, and reload
• QuickCast: paste any table and extract a clean number grid with select, move, flip, round, and balance tools
• Visual key hints, a text-entry mode for notes in the trail, and a dark mode toggle

Test whether unutilised capital allowances, trade losses and donations survive a change in ownership — the >50% common shareholder test between relevant dates.

• Paste or enter shareholding movements and loss items — results auto-update as you type
• Balance history and common-shareholder analysis calculated per relevant date pair
• PDF or Excel download, no sign-in — and fully client-side, so nothing leaves your browser

Drop Singapore bank statement PDFs — DBS Corporate format supported — and extract structured transaction data in seconds. Several statements open as independent tabs, then consolidate into one export.

• Entity details and a transaction table with checksum validation and editable cells
• Configurable push settings for date, description, and signed amount columns
• CSV export or copy to clipboard, sorted by date — extraction is client-side, so the PDF stays with you

Two Monetary Authority of Singapore rate workpapers in one place: Average Exchange Rate averages the published monthly rates over a period of up to thirteen months, and Daily Valuation prices a list of dated transactions at the daily rate for each transaction’s own date.

• 22 currencies including KYD, read live from the MAS statistical bulletin — monthly and daily series, refreshed daily
• Paste transactions straight from a statement or ledger and the extractor lays them out as dates, descriptions and amounts; weekend and holiday dates carry the last published rate and say which date they used
• Drop any month from the average by clicking it, then copy the rate, copy the table, or take the full-precision CSV

Per-country summaries of Singapore’s comprehensive double taxation agreements — withholding caps, permanent-establishment thresholds and the 183-day employment basis — every fact carrying its treaty article number so it can be checked in seconds. Runs entirely in your browser.

• Quick withholding lookup: treaty cap versus domestic rate, the gross-up when the payer bears the tax, and the section 45 filing deadline
• The traps surfaced — the 183-day basis (calendar year versus any twelve-month period), construction-PE months, and limitation-of-relief / remittance clauses
• The no-comprehensive-treaty list, with the United States and Hong Kong caught explicitly

Paste renovation invoice lines and get a section 14N workpaper, with every line classified as qualifying, non-qualifying, or plant & machinery that belongs in a capital allowance claim instead.

• Bulk discounts spread pro-rata with largest-remainder rounding — totals always tie to the dollar
• GST shown as a separate claimable column or kept in the cost, including the single-GST-line case when the list spans several invoices
• S$300,000 cap tracked against prior claims, with the 3-YA or 1-YA deduction schedule

Paste a fund’s investment list and test each line against the Third Schedule, Part A — designated investments under the Singapore fund tax exemptions (sections 13D, 13O, 13U). Every item comes back Designated, Not designated, or Further analysis required.

• Deterministic keyword matching to the (a)–(x) categories, with a confirm step for near-misses
• Listing, Singapore immovable property and counterparty questions asked only where they matter
• Summary totals by qualifying status, with an optional SGD conversion — a quick email verification unlocks the analysis

Three GST checks in one place: expense lines tested for blocked input tax (Regs 26 & 27) and reverse-charge triggers, income lines sorted into standard-rated, zero-rated, exempt and out-of-scope, and F5 sanity checks before filing. A quick email verification unlocks classification; pasted lines are never stored.

• Blocked input tax flagged with the regulation cited — S-plate cars, club subscriptions, medical costs — and the counter-intuitive ones marked claimable (entertainment is not blocked for GST)
• A three-question s21(3) walkthrough resolves whether an international service zero-rates — a decision tree, not keyword guesswork
• F5 ties: output tax vs 9% of Box 1, reverse-charge boxes, input-tax ceiling, and the De Minimis test for exempt supplies

The single-user version: track each compliance engagement from fee quote to Notice of Assessment. No sign-in, nothing leaves your browser, JSON export for backup.

• Stages dated from the FYE — draft accounts at day 45, ECI within 3 months, final accounts from month 7, filing by 30 November, then the NOA check (IRAS query cases run a shorter engage → draft → review → send flow)
• Chaser counters on requests, preparer → senior → manager escalation and a three-level review chain
• Quote, scope-of-work and draft-bill templates that merge each case’s details, with billing tracked quoted → engaged → invoiced → paid on due-soon and overdue dashboards

Enter plant & machinery — or paste rows straight from a fixed asset register — and get the Year of Assessment claim: initial and annual allowances, balancing adjustments on disposals, and tax written-down values carried forward. Runs entirely in your browser.

• Descriptions auto-classified on paste: computers to the 1-year write-off, S-plate cars and land excluded, renovation cross-flagged to s14N
• Every claim method: s19A one-year and three-year write-offs, low-value pooling, s19 working lives, the accelerated 75/25 option
• The s19A(10A) low-value cap watched for you — a warning the moment a YA’s claims cross S$30,000

Assemble Singapore tax letters and client emails from a curated library of standard paragraphs — tax packages, information request lists, filing reminders, fee quotes. Runs entirely in your browser; Word and PDF downloads unlock with just your email.

• Client details picked out of any pasted text — a BizFile extract, an email signature, your own notes — then filled into every placeholder for you
• Ready-made letter and email templates, with numbered paragraphs for easy reference
• Abbreviations written in full at first use (IRAS, ECI, GST…) and shortened after — automatically

Load two Excel files side by side in a preview that mirrors Excel itself — column letters, row numbers and sheet tabs — and see the differences highlighted. Runs entirely in your browser; nothing is uploaded.

• Rows paired by their shared cells, each changed pair in its own colour so the two sides match by eye — reordered rows still pair up, and rows in only one file read like a code diff
• Cell mode is position-blind: a value with no match anywhere on the other sheet is flagged, for sheets that don’t share a layout
• Synchronised scrolling, per-sheet tab selection, column-range exclusions for side notes, and difference counts for each side

What Preview does on a Mac, in the browser for everyone else — load one or more PDFs, arrange their pages as thumbnails, then join, reorder, rotate, delete or extract pages and download the result. Runs entirely in your browser; nothing is uploaded.

• Drag pages to reorder — including between files — with a colour-coded tag on every page naming the file it came from
• Select any set of pages to rotate, delete or extract into a PDF of their own; deletions carry a five-second Undo
• Joining is simply loading more than one file — the download stitches whatever is in the tray, in tray order, into a single PDF
