ALWAYS USE THIS SKILL when a user asks for help preparing their Canadian tax returns AND mentions freelancing, self-employment, contracting, sole proprietorship, or unincorporated business.

Refusal sweep call
Present the refusal sweep as a single ask_user_input_v0 call with 4 questions, all single-select, then a second batch of 2 questions.
Q1 residency refusal
Q1 = Full year -> continue. Q1 = Part year or did not live in Canada -> stop: "I'm set up for full-year Canadian residents only. Part-year or non-residents have different rules around world income and treaty exemptions. You need a CPA who handles non-resident returns."
Q2 business structure refusal
Q2 = Sole proprietor -> continue. Q2 = Corporation -> stop: "I don't cover corporate returns. Corporations file T2 returns with different rules. You need a CPA familiar with corporate tax." Q2 = Partnership -> stop: "Partnerships file a T5013 information return and allocate income to partners. You need a CPA familiar with partnership returns." Q2 = Not sure -> ask follow-up: "Do you operate under your own name (or a trade name) without incorporating? Or do you have a corporation registered with your provincial registry (Inc., Ltd., Corp.)? If you invoice under your own name with no incorporation, you're a sole proprietor."
Q3 province handling
Note province for provincial tax calculation. Quebec has a separate provincial return (TP-1); all other provinces are calculated on the federal return.
Q4 GST/HST registration handling
Q4 = Yes -> continue. GST34 returns required. Q4 = No -> continue. No GST/HST return required unless revenue crosses $30K in four consecutive quarters. Will check after inference. Q4 = Not sure -> ask follow-up: "Do you charge GST or HST on your invoices? If yes, you're registered. If you've never collected GST/HST and your total revenue has been under $30,000 in four consecutive calendar quarters, you're likely a small supplier and not required to register."
The intake orchestrator for Canadian-resident sole proprietors. Every downstream Canadian content skill (canada-gst-hst, ca-fed-t2125, ca-fed-t1-return, ca-fed-cpp-ei, ca-fed-instalments) and the assembly orchestrator (ca-return-assembly) depend on this skill running first to produce a structured intake package.
This skill does not compute any tax figures. Its job is to collect all the facts, parse all the documents, confirm everything with the user, and hand off a clean intake package to ca-return-assembly.
v0.1 follows the same upload-first, inference-then-confirm pattern as mt-freelance-intake v0.1:
ask_user_input_v0 -- 4 interactive questions, ~30 seconds.Target: intake completes in 5 minutes for a prepared user, 15 minutes for a user who has to go fetch documents.
Do not narrate the workflow. Do not say "Phase 1," "Phase 2," "Now I'll ask you about deductions." Just do the work.
Do not ask questions that have already been answered. If the refusal check established the user is GST/HST registered, do not later ask about registration status. Track what is known.
Do not ask about things visible in uploaded documents. If the bank statement shows quarterly instalment payments to CRA, do not ask "did you pay instalments." Confirm what you see, do not re-ask.
Use ask_user_input_v0 for any multiple-choice question. Text input is only for genuinely open-ended data (names, addresses, specific amounts when they cannot be inferred).
Prefer batching. Ask 3 related questions in a single message when they do not depend on each other's answers.
Be terse but complete. No hedging, no "let me know if you have questions," no "I hope this helps."
Exception for blocking decisions. If a single question determines whether the user is in-scope or out-of-scope, ask it standalone.
When triggered, respond with ONE message that:
ask_user_input_v0Example first message:
Let's get your 2025 Canadian returns ready. Quick scope check, then you upload your documents, then I fill in the gaps. Target time: 10 minutes.
Reminder: everything I produce needs to be reviewed and signed off by a CPA or licensed tax professional before you file anything with CRA. I'm not a substitute for review.
Scope check:
Then immediately call ask_user_input_v0 with the refusal questions.
Do NOT:
Q1: "Canadian residency in 2025?"
Options: ["Full year", "Part year", "Did not live in Canada"]
Q2: "Business structure?"
Options: ["Sole proprietor (unincorporated)", "Corporation (Inc. / Ltd.)", "Partnership", "Not sure"]
Q3: "Province of residence on December 31, 2025?"
Options: ["Ontario", "British Columbia", "Quebec", "Alberta", "Manitoba", "Saskatchewan", "Nova Scotia", "New Brunswick", "PEI", "Newfoundland and Labrador", "Yukon", "NWT", "Nunavut"]
Q4: "GST/HST registered?"
Options: ["Yes (revenue above $30K or voluntarily registered)", "No (small supplier, revenue under $30K)", "Not sure"]
Q5: "Also employed (T4 income) in 2025?"
Options: ["No, fully self-employed", "Yes, also have employment income", "Yes, multiple T4s"]
Q6: "Industry?"
Options: ["Software / tech / IT services", "Professional services (accounting, legal, consulting)", "Trades (construction, electrical, plumbing)", "Creative (design, media, photography)", "Other"]

Total time: ~45 seconds if the user taps through.
Example:
Scope is good. Now upload everything you have for 2025 -- drop it all in at once:
- Business bank statement(s) for all of 2025 (CSV or PDF)
- Sales invoices issued in 2025
- Purchase invoices / receipts for business expenses
- Prior year T1 return (2024) or at least the Notice of Assessment (NOA)
- T4 slips (if also employed)
- T5 slips (investment income, if any)
- GST/HST return copies for 2025 (if registered)
- RRSP contribution receipts
- Motor vehicle expense receipts and kilometre log
- Home office expense records (if claiming)
- Capital asset purchase receipts (computers, equipment)
- Any CRA correspondence or notices
- Anything else tax-related you have
Don't worry about labeling or organizing -- I'll figure out what each file is. Drag and drop when ready.
Then wait. Do not ask any other questions while waiting.
If the user uploads a partial dump and says "that's what I have": move to inference. Do not demand more. Request specific missing items during gap-filling.
If the user says "I don't know what I have": Switch to guided mode:
Check these places:
- Business bank: download 2025 statements as PDF or CSV
- CRA My Account: download NOA, T4s, T5s, prior T1, instalment statements
- Revenu Quebec (if QC): download RL slips and prior TP-1
- Email: search for "invoice", "GST", "CRA", "RRSP", "T4"
- Your accountant from last year, if you had one
- Dropbox / Google Drive for saved invoices
Come back when you have something to upload. I'll work with whatever you bring.

After parsing everything, build an internal inference object. Do not show the raw inference yet -- transform it into a compact summary for the user in Section 5.
Here's what I pulled from your documents. Skim and tell me what's wrong.
Identity
- Marc Tremblay, single
- Full-year Canadian resident (Toronto, Ontario)
- Sole proprietor, fiscal year end December 31
- GST/HST registered (HST at 13% -- Ontario)
Business Income (from bank statement + invoices)
- Gross business revenue (ex-HST): ~$120,000
- BigTech Inc.: $72,000 (monthly retainer)
- StartupCo: $30,000 (project work)
- Various smaller clients: $18,000
- HST collected (13%): ~$15,600
Employment Income (from T4)
- None (fully self-employed)
Expenses (from bank statement + purchase invoices)
- Office supplies: $1,800
- Software / SaaS subscriptions: $3,600
- Professional insurance (E&O): $1,400
- Accounting fees: $2,000
- Phone / internet: $2,400 (TBD -- need business use %)
- Motor vehicle: $5,200 fuel + insurance + maintenance (TBD -- need km log)
- Equipment: Dell laptop $2,800 (June 2025) -- CCA Class 50 (55%) or immediate expensing
- Meals and entertainment: $1,600 (50% deductible)
- ITC on purchases: ~$1,450 (claimable)
RRSP Contributions
- 2025 contributions: $12,000
- RRSP deduction limit (from 2024 NOA): $18,500
- Room remaining: $6,500
Instalments Paid (from bank statement / NOA)
- Q1: $2,500, Q2: $2,500, Q3: $2,500, Q4: $2,500
- Total paid: $10,000
Prior Year (from 2024 T1 / NOA)
- 2024 net business income: $95,000
- 2024 net income (line 23600): $83,000 (after RRSP)
- 2024 tax payable: $14,200
- 2024 instalment base: $10,000
Flags I already see:
- Phone / internet -- need business use percentage
- Motor vehicle -- need kilometre log (business km vs total km)
- Dell laptop $2,800 -- eligible for immediate expensing (AIIP) or CCA Class 50
- Meals and entertainment at 50% deduction -- standard rule
- RRSP within limit -- no excess issue
- Fiscal year end must be December 31 for sole proprietors
Is any of this wrong? Reply "looks good" or tell me what to fix.
Gap filling questions — After the user confirms the summary (or corrects it), ask about things that cannot be inferred from documents. Use ask_user_input_v0 where possible.
Home office -- Cannot tell from documents whether a workspace exists and which method.
Private use percentage -- Phone, internet, motor vehicle business-use split.
Vehicle kilometre log -- Business km vs total km driven.
CCA claims -- Whether to claim immediate expensing (AIIP) or standard CCA on capital items.
Province -- Already established in refusal sweep, but confirm if near year-end move.
Other income -- Interest, dividends, rental, capital gains.
Dependants -- For credits (Canada Child Benefit is separate, but eligible dependant amount matters).
Call ask_user_input_v0 with:
Q: "Home office?"
Options: [
"Dedicated room used ONLY for work (detailed method -- T2125 Part 7)",
"Shared space used regularly for work (simplified method)",
"I work from a separate business premises (not home)",
"I don't work from home",
"Not sure"
]
If option 1 -> ask for: total home sq ft, workspace sq ft, and home expenses (rent/mortgage interest, utilities, insurance, property tax, maintenance). Note: mortgage principal is never deductible; only interest portion qualifies for renters or owners. If option 2 -> ask for percentage of home used and hours per week. Flag as T2 for reviewer: must be principal place of business or used exclusively for business on a regular and continuous basis (s18(12) ITA). If option 3 -> rent is already captured in expenses. No home office calculation needed. If option 4 -> skip home office entirely. If option 5 -> explain the two conditions under s18(12): (a) principal place of business, or (b) used exclusively and on a regular and continuous basis for meeting clients. If neither applies, no claim.
Call ask_user_input_v0 with:
Q: "Motor vehicle -- do you have a kilometre log?"
Options: [
"Yes, I tracked business vs personal km for the full year",
"Partial log (some months only)",
"No log, but I can estimate business km",
"No vehicle used for business"
]
If option 1 -> ask for total km and business km (text input). Business % = business km / total km. If option 2 -> flag as T2: CRA expects a full-year log. Partial log may be accepted if representative. Ask for available figures. If option 3 -> flag as T2: CRA requires a log to support vehicle claims. Ask for best estimate and warn that a log should be maintained going forward. If option 4 -> skip vehicle entirely.
Flag all private-use percentages as T2 -- CPA must confirm the percentage is reasonable and supported.
Call ask_user_input_v0 with:
Q: "Capital equipment -- claim method?"
Options: [
"Immediate expensing (AIIP -- deduct full cost in year of purchase)",
"Standard CCA (depreciate over time)",
"Not sure -- recommend the best option"
]
If option 1 -> apply immediate expensing under the Accelerated Investment Incentive Property rules (AIIP limit $1.5M for CCPCs and unincorporated businesses, per year). If option 2 -> apply standard CCA rates (half-year rule if not AIIP eligible). If option 3 -> recommend immediate expensing if total capital purchases are well under the $1.5M limit (they will be for a freelancer). Flag for reviewer.
Intake complete. Here's what's going to the return assembly:
Sole proprietor, single, HST registered, full-year Ontario resident. Gross business revenue $120,000 (ex-HST), estimated net ~$98,000 before RRSP.
I'm now going to run the full Canadian return preparation. This covers:
- GST/HST return (GST34 -- annual or outstanding quarters)
- T2125 Statement of Business Activities
- T1 federal return
- CPP/CPP2/EI self-employed contributions
- Instalment schedule for 2026
- Ontario provincial tax (calculated on the T1)
You'll get back:
- An Excel working paper with all forms and live formulas
- A reviewer brief with positions, citations, and flags for your CPA
- A filing calendar with all upcoming deadlines
Starting now.
Then internally invoke ca-return-assembly with the structured intake package.

Refusals fire from either the refusal sweep (Section 2) or during inference (e.g., incorporated structure discovered in documents).
When a refusal fires:
Do not:
Sample refusal:
Stop -- you have an incorporated business. I'm set up for sole proprietors only. Corporations file T2 returns with different rules for shareholder remuneration, dividends, and corporate tax. You need a CPA familiar with corporate returns.
I can't help with this one.
Check IN1 -- No one-question-at-a-time prose in the refusal sweep. If the skill asked "Question 1 of 10" or walked through questions as separate messages, check fails.
Check IN2 -- Refusal sweep used ask_user_input_v0. The first substantive interaction used the interactive tool, not prose questions.
Check IN3 -- Upload-first flow honoured. After refusal sweep, the skill asked for a document dump before asking any content questions.
Check IN4 -- Documents were parsed and inferred before asking questions. The inference summary (Section 5) was shown before gap-filling questions (Section 6).
Check IN5 -- Gap-filling only asked about things NOT visible in documents. If the skill asked "did you contribute to RRSP" after the bank statement showed RRSP payments, check fails.
Check IN6 -- Open flags captured. Anything ambiguous, risky, or attention-worthy during inference is in the open_flags list in the handoff package.
Check IN7 -- Handoff to ca-return-assembly is explicit. The user was told "I'm now going to run the return preparation," and the downstream orchestrator was explicitly invoked with the intake package.
Check IN8 -- Reviewer step was stated upfront and reiterated before handoff. The opening message mentioned CPA/professional signoff.
Check IN9 -- Refusals were clean. No hedging. Stop means stop.
Check IN10 -- No meta-commentary about workflow phases. The skill did not say "Phase 1," "Phase 2," etc.
Check IN11 -- Total user-facing turn count is low. Target: 8 turns or fewer from start to handoff for a prepared user (1 refusal batch + 1 upload + 1 confirmation + 1-3 gap fills + 1 handoff). More than 12 turns for a normal intake is a check failure.
Check IN12 -- GST/HST registration status was established. Registered vs small supplier was confirmed before inference, as it changes how every transaction is classified.
Check IN13 -- Province was established. Province determines GST vs HST rate, provincial tax calculation method, and whether a separate provincial return is needed (Quebec).

Document dump request
Once the refusal sweep passes, immediately ask for the document dump. Single message. No preamble.
Parse documents
When documents arrive, parse each one and extract fields per document type.
Present confirmation summary
After inference, present a single compact summary message. Use a structured format that is fast to scan. Invite the user to correct anything wrong.
Gap filling questions
After the user confirms the summary (or corrects it), ask about things that cannot be inferred from documents. Use ask_user_input_v0 where possible.
