Personal LOC to Business — Funding Mechanics
Owner: Mahdi Moradi Status: Draft Version: 1.0.0 Last Updated: 2026-03-19 Applies To: Bornara AI
Overview
This document explains how to use your available Lines of Credit (LOC) to fund Bornara AI operations through your dedicated RBC business bank account — including which LOC to draw from, the mechanics of each draw, interest deductibility, minimum payments, and CRA documentation requirements.
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 |
Disclaimer: Based on publicly available CRA guidance. Consult a qualified tax professional for advice specific to your situation.
Account Setup
| Account | Owner | Bank | Limit | Use |
|---|---|---|---|---|
| Personal LOC (primary) | Mahdi | BMO | $12,000 | Fund source — do NOT spend directly |
| Personal LOC (secondary) | Narjes | RBC | $32,000 | Fund source — do NOT spend directly |
| Business Bank Account | Mahdi | RBC | — | All business spending goes here |
Golden Rule: Money flows in one direction only:
Mahdi BMO LOC ─────────────────────────────────────────┐
↓
RBC Business Account → Business Expenses
↑
Narjes RBC LOC ────────────────────────────────────────┘
Never pay business expenses directly from either LOC. Always transfer to the RBC business account first. This creates a clean paper trail that CRA can follow.
Why Mahdi's BMO LOC First?
- Lower interest rate (~9–11% vs ~10–12%)
- Fully under Mahdi's control — no need to involve Narjes for every draw
- Reserve Narjes's RBC LOC for larger needs (equipment, significant ad spend)
Why Narjes's RBC LOC Second?
- Higher limit ($32K vs $12K) — essential once Mahdi's BMO is maxed
- Same bank as the business account — RBC internal transfers are instant and free
- Narjes must authorize each draw (she is the account holder)
- Document her consent: a quick text/email confirmation is sufficient backup
Important — CRA and spousal LOC: When Narjes's LOC funds the business, the interest deductibility still applies as long as: (1) funds go to the business account, (2) the draw is logged, and (3) there is a clear business purpose. Consult your accountant before claiming — this is an area where documentation quality matters.
Step-by-Step: How to Make a Draw
Step 1 — Determine the Need
Before each draw, identify the specific business expenses it will cover:
Example:
Date: 2026-04-03
Amount: $2,500
Purpose: Shopify subscription ($39), laptop purchase ($1,800),
Shopify apps ($50), ad budget ($300), wife wages ($311)
Step 2 — Transfer from LOC to Business Account
If drawing from Mahdi's BMO LOC:
- Log into BMO online banking
- Transfer from BMO Personal LOC → your RBC Business Account (Interac e-Transfer or pre-authorized transfer)
- Screenshot the transfer confirmation (date, amount, from/to accounts)
- Save the screenshot in CRA folder:
10. LOC Funding/Draw transfer screenshots/
If drawing from Narjes's RBC LOC:
- Narjes logs into RBC online banking
- Internal transfer: RBC Personal LOC (Narjes) → RBC Business Account (Mahdi) — same bank, instant
- Screenshot the transfer confirmation
- Save in same CRA folder — note the source ("Narjes RBC LOC")
- Keep a record of Narjes's authorization (text message or email is fine)
Step 3 — Log the Draw
Record every draw in the 2026 Expense Log and in the tracking table below.
How to update this log: You do not need an Excel sheet. Just tell the AI:
"I drew $2,000 on April 3 from BMO for Shopify setup and ads" and it will fill in the row for you. Or edit the markdown table directly in VS Code.
The log lives in this document — no separate spreadsheet required.
Step 4 — Spend from Business Account Only
All business purchases, subscriptions, wages, and ad payments come from the business bank account. This creates:
- Bank statements showing exactly what was purchased
- Clear separation between personal and business spending
- Audit-ready trail for CRA
Step 5 — Track Interest
BMO charges interest monthly on your LOC balance. The portion of interest attributable to business draws is 100% deductible.
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) |
