Personal LOC to Business — Funding Mechanics
Owner: Mahdi Moradi Status: Active Version: 2.0.0 Last Updated: 2026-04-28 Applies To: Bornara AI
Overview
This document explains how Bornara AI (sole proprietorship) handles finances when business expenses are paid through a mix of personal credit cards, PayPal, LOC, and a business checking account.
Key insight: As a sole proprietor, you and the business are the same legal entity. You don't need to route every dollar through the business account. The CRA cares about documentation, not which card swiped.
Accounts in Play
| Account | Type | Owner | Use |
|---|---|---|---|

Current Balances (April 28, 2026)
| Account | Balance |
|---|---|
| BMO LOC | $0 (cleared) |
| BMO Credit Card | $90 (Microsoft 365) |

You have two LOC sources available now, with room to add more later:
| Source | Owner | Bank | Limit | Rate (approx.) | Priority |
|---|---|---|---|---|---|
| Personal LOC | Mahdi | BMO | $12,000 | ~9–11% variable | Draw first |
| Personal LOC | Narjes (wife) | RBC | $32,000 | ~10–12% variable (+1%) | Draw second |
| Future LOC(s) | TBD | TBD | TBD | TBD | Add later |
Current Status (April 2026)
| Item | Amount |
|---|---|
| BMO LOC balance owed | ~$16,000 (over limit — includes mixed personal + business spending) |
| Business expenses paid from personal | Significant — cookies, subscriptions, domains, hosting |
| Interest deductible so far | None yet — no tracking system in place |
| RBC Business Account | Exists but not yet primary payment method |
⚠️ Critical 2026 Action: Transition ALL business payments to the RBC Business Account ASAP. Once payments flow through the business account funded by LOC draws, the interest on those draws becomes deductible. Interest on mixed personal/business LOC spending is NOT deductible unless you can prove exactly which portion funded business expenses.
For 2025 interest: You can retroactively claim LOC interest proportional to business expenses, BUT you need to:
- Calculate what % of LOC draws went to business vs personal
- Apply that % to total interest paid in 2025
- Have bank statements to back it up
- This is complex and amounts may be small — consider starting clean in 2026 instead.
2026 Plan: Every business dollar goes through RBC Business Account. LOC → RBC → Expense. Then 100% of interest on those LOC draws is deductible on T2125 Line 8710 (Interest).
Disclaimer: Based on publicly available CRA guidance. Consult a qualified tax professional for advice specific to your situation.
The System — 3 Payment Methods
Method 1: Personal Credit Card (BMO) → Reimbursement
Use for: Online purchases, subscriptions, anything that needs a credit card. Why: RBC business account has no credit card. Plus you get cashback.
How it works:
- Pay the business expense with your BMO credit card (or PayPal linked to it)
- Keep the receipt / invoice / PayPal confirmation
- Periodically, reimburse yourself from the RBC business account
- The reimbursement shows as: "Owner reimbursement — [list of expenses]"
Example:
Apr 5 — BMO CC: Microsoft 365 ($36)
Apr 5 — BMO CC: GitHub Copilot ($20)
Apr 10 — PayPal: IONOS hosting ($12.60)
Apr 15 — BMO CC: Cookie supplies ($100)
Apr 28 — RBC Business → BMO CC payment: $168.60 (reimbursement)
CRA doesn't care which card you used. They care that:
- The expense is documented (receipt/invoice)
- It's a legitimate business expense
- You can explain it if asked
Cashback: You keep the cashback. It's technically taxable income but on small amounts CRA won't chase it.
Method 2: RBC Business Account — Direct
Use for: Narjes wages (e-transfer), direct debits, any vendor that takes bank payment.
RBC Business Account → e-Transfer to Narjes ($600/mo wages)
RBC Business Account → Direct debit (if any vendor supports it)
Method 3: LOC → RBC Business Account (Funding)
Use for: Loading money into the business account when it's low.
BMO LOC → RBC Business Account (Interac e-Transfer)
Then: RBC Business pays expenses OR reimburses your credit card
This is the ONLY scenario where LOC interest becomes deductible. The draw must go to the business account first. Then the business spends it.
The Golden Rule (Simplified)
┌─────────────────────────────────────────────────────────────┐
│ EVERY business expense gets ONE of these treatments: │
│ │
│ A) Paid from RBC Business Account directly │
│ → Already tracked. Done. │
│ │
│ B) Paid from personal card / PayPal │
│ → Log it. Reimburse yourself from RBC Business monthly. │
│ │
│ C) Paid from LOC directly (avoid this) │
│ → Interest is NOT cleanly deductible. │
│ → Transfer LOC → RBC Business first, THEN spend. │
└─────────────────────────────────────────────────────────────┘
Do NOT pay business expenses directly from LOC. Transfer to RBC Business first. DO use personal credit card freely — just reimburse yourself monthly.
Monthly Reimbursement Process
At the end of each month:
- List all business expenses paid from personal cards/PayPal this month
- Total them up
- Transfer that exact total from RBC Business Account → your BMO credit card (or your personal bank account, then pay the card)
- Log it: "Owner reimbursement — April 2026 — $XXX — [summary of expenses]"
If RBC Business Account is empty:
- Transfer from BMO LOC → RBC Business Account first
- Then reimburse yourself from RBC Business
- This makes the LOC draw traceable to business expenses → interest deductible
The BMO Credit Card $90
That $90 for Microsoft 365 — just pay it normally. Log it as a business expense. At month-end, reimburse yourself from RBC Business. Don't overthink it.
Getting Paid Back for Past Expenses
You've already spent personal money on business items. Here's how to make it clean:
Step-by-Step: How to Handle a Draw + Reimbursement
Scenario A: You Need to Fund the Business Account
- Transfer from BMO LOC → RBC Business Account (Interac e-Transfer)
- Screenshot the transfer
- Log the draw in the tracking table below
- Now spend from RBC Business, or reimburse yourself for personal card expenses
Scenario B: You Already Paid with Personal Card
- Keep the receipt (email confirmation, PayPal receipt, credit card statement)
- At month-end, total up all personal-card business expenses
- Transfer that total from RBC Business → your personal account / BMO CC
- Memo: "Owner reimbursement — [month] — $[amount]"
- If RBC Business is empty, do Scenario A first
Past Expenses (2026 so far) — One-Time Catch-Up
Make a single list of everything you've paid personally for business in 2026. Do one lump reimbursement from RBC Business (funded by LOC if needed):
| Item | Approx. Amount | Paid Via |
|---|---|---|
| KitchenAid mixer (cookies) | $350 | Personal CC/cash |
| Cookie materials/ingredients | $100 | Personal CC/cash |
| Microsoft 365 (2 users × ~$18) | ~$36/mo | BMO CC |
| GitHub Copilot | ~$20/mo | PayPal |
| IONOS domains/hosting | ~$14/mo | PayPal |
| Other subscriptions | TBD | Various |
| Home utilities (business %) | TBD | Personal |
Action: Calculate the total, draw that amount from BMO LOC → RBC Business, then transfer from RBC Business → your personal account as "owner reimbursement." This creates a clean paper trail retroactively.
Draw Tracking Log (2026)
The table tracks all draws across both LOC sources. The "LOC" column tells CRA exactly where each draw came from.
| Draw # | Date | Amount | LOC Source | Purpose | BMO/RBC Ref # |
|---|---|---|---|---|---|
| 1 | |||||
| 2 | |||||
| 3 | |||||
| 4 | |||||
| 5 | |||||
| 6 |
Available credit by source:
| Source | Limit | Drawn YTD | Remaining |
|---|---|---|---|
| Mahdi — BMO LOC | $12,000 | $0 | $12,000 |
| Narjes — RBC LOC | $32,000 | $0 | $32,000 |
| Total | $44,000 | $0 | $44,000 |
Strategy: Draw from Mahdi's BMO first (lower rate). Switch to Narjes's RBC once BMO is near its $12K limit. Keep total drawn under actual business need — do not draw speculatively.
Interest Mechanics
How LOC Interest Works
| Item | Mahdi — BMO LOC | Narjes — RBC LOC |
|---|---|---|
| Rate | ~9–11% variable | ~10–12% variable (+1%) |
| Calculation | Daily on balance, charged monthly | Daily on balance, charged monthly |
| Minimum payment | Interest only | Interest only |
| Payment due | Monthly — check BMO statement | Monthly — check RBC statement |
| Transfer method to business | Cross-bank (Interac e-Transfer) | Internal RBC transfer (instant/free) |
Interest Cost Examples
Using 10% for BMO draws and 11% for RBC draws (conservative mid-range estimates):
| Scenario | BMO Balance | RBC Balance | Annual Interest | Monthly Interest |
|---|---|---|---|---|
| Small start | $5,000 | $0 | ~$500 | ~$42 |
| BMO maxed | $12,000 | $0 | ~$1,200 | ~$100 |
| BMO + partial RBC | $12,000 | $10,000 | ~$2,300 | ~$192 |
| Both near limit | $12,000 | $30,000 | ~$4,500 | ~$375 |
Who Pays the Interest
The business pays the interest. In practice:
- BMO / RBC charges interest to the respective personal LOC monthly
- Transfer the interest amount from the RBC business account → each LOC to cover it
- Log as a business expense (T2125 Line 8710 — Interest) — split by LOC source if using both
- The interest payment is 100% tax deductible because the borrowed money was used exclusively for business
Who Pays the Minimum Payment
- Minimum payment on both LOCs is typically interest only
- Once the business has revenue, use revenue to pay down principal
- Until then, the interest-only minimum is covered by the RBC business account (funded by the LOC itself if needed — this is normal for startups)
- Pay BMO LOC minimum from RBC business account via Interac e-Transfer to yourself
- Pay RBC LOC minimum from RBC business account via internal transfer (free)
Monthly Routine
Every month, do the following:
End of Month Checklist
- Download BMO LOC statement (Mahdi — draws, interest, balance)
- Download RBC LOC statement (Narjes — draws, interest, balance) if used
- Download RBC business account statement (all spending)
- Record interest charged this month from each LOC in the expense log
- Transfer interest amount from RBC business account → BMO LOC (Interac e-Transfer)
- Transfer interest amount from RBC business account → RBC LOC if applicable (internal)
- Update the Draw Tracking Log and Available Credit table above
- File all statements in CRA documentation folder
CRA Deductibility Rules
What Is Deductible
| Item | Deductible? | T2125 Line | Notes |
|---|---|---|---|
| Interest on Mahdi's BMO LOC (business draws) | Yes | Line 8710 | Must trace to business use |
| Interest on Narjes's RBC LOC (business draws) | Yes | Line 8710 | Same rules; consult accountant |
| Bank fees (RBC business account) | Yes | Line 8810 | Office expenses |
| Interac e-Transfer fees (BMO→RBC) | Yes | Line 8810 | If charged |
| Principal repayment | No | — | Not an expense |
What CRA Requires
- Trace each draw to a business expense — the log above does this, per LOC source
- Each LOC must be used exclusively for business — do NOT use either LOC for personal expenses once you start drawing for business; if Narjes's LOC is also used personally, you must prorate
- Keep bank statements — BMO LOC, RBC LOC, and RBC business account, every month
- Interest statements — BMO and RBC both provide these monthly and annually
- Narjes's authorization — keep a record (text/email) that she consented to each draw from her LOC for business purposes
Mixed-Use Warning
If Narjes uses her RBC LOC for both personal and business expenses:
- You must prorate the interest (business % only is deductible)
- This is complex and audit-risky
- Strong recommendation: Reserve Narjes's RBC LOC for business draws only during active business periods. If she needs personal credit, use a different product or timing.
Mahdi's BMO LOC should be 100% business-use from the first draw forward.
Repayment Strategy
Phase 1: Pre-Revenue (Q1–Q2 2026)
- Business has no revenue yet
- Draw from Mahdi's BMO LOC first (lower rate, simpler — one person)
- Interest is covered by the LOC itself if needed — this is normal for startups
- Keep draws small and targeted; avoid speculative draws
Phase 2: BMO Near Limit / Scaling (Q3–Q4 2026)
- If Mahdi's BMO LOC approaches $12K, begin drawing from Narjes's RBC LOC
- Each draw from Narjes's LOC requires her authorization (document it)
- Business revenue should start covering interest-only minimums
- Principal stays outstanding — focus on growing the business
Phase 3: Revenue Growth (2027+)
- Revenue covers interest AND starts paying down principal
- Pay off Mahdi's BMO LOC first (higher-cost relative to Narjes's if both are active)
- Actually: pay off whichever has higher outstanding balance × rate — recalculate annually
- Aim to reduce total LOC balance by $5,000–$8,000/year from business revenue
If Business Revenue Doesn't Cover Interest
- Mahdi's day job income ($94K) easily covers the monthly interest
- At full combined draw ($44K at ~10.5% avg): ~$385/month max — manageable
- Transfer from personal checking → respective LOC to cover the difference
- This is NOT a business expense — only the interest on business-use draws is deductible
Risk Scenarios
| Scenario | Impact | Action |
|---|---|---|
| Business fails, $12K BMO outstanding | ~$1,200/yr interest | Day job covers it; pay down over 1–2 years |
| Business fails, $12K BMO + $20K RBC outstanding | ~$3,400/yr interest | Still manageable on $94K salary |
| Interest rate rises to 14% | +$400–$600/yr per $10K | Prioritize repayment; stay under limit |
| Narjes's LOC used for personal items too | Lose partial deductibility | Keep her LOC business-only or prorate carefully |
| CRA questions Narjes's LOC draws | Need her authorization records | Text/email consent + draw log = clean proof |
| BMO maxed, RBC not yet activated | Can't draw more from BMO | Activate Narjes's RBC LOC in advance (don't wait until you're stuck) |
