Registered Retirement Savings Plans (RRSPs) and Tax-Free Savings Accounts (TFSAs) are two of Canada’s most popular tax-advantaged accounts. But overcontributing to either can result in significant tax penalties. In this guide, we explain how to avoid overcontributions, how to check your limits, and what to do if you go over.

📌 What Is an Overcontribution?
An overcontribution occurs when you deposit more than your available contribution room into your RRSP or TFSA. While both accounts offer generous annual limits, exceeding those limits can trigger tax consequences.
💸 RRSP Overcontributions
Each year, your RRSP contribution room is based on 18% of your previous year’s earned income, up to an annual limit set by the CRA (e.g. $31,560 in 2025). You can carry forward unused room from prior years.
🚨 What Happens If You Overcontribute?
- You are allowed a $2,000 lifetime buffer for overcontributions without penalty
- Anything above the buffer is subject to a 1% monthly tax on the excess amount
- Penalties apply until the excess amount is withdrawn or new room becomes available
📑 TFSA Overcontributions
Unlike RRSPs, TFSA contribution room is the same for all Canadians aged 18+ (e.g. $7,000 in 2025), regardless of income. Contribution room accumulates annually and carries forward indefinitely.
⚠️ Penalty for TFSA Overcontributions
- 1% tax per month on the highest excess amount for each month overcontributed
- Applies even if you withdraw the funds later in the same year
- CRA may issue a TFSA return (Form RC243) and a demand for payment
🛠️ How to Check Your Contribution Limits
- Login to your CRA My Account
- Go to “RRSP and TFSA” tabs to view latest limits
- TFSA limits update annually in January; RRSP room is based on prior year’s tax return

📤 How to Fix an Overcontribution
If you’ve overcontributed to your RRSP or TFSA:
- Withdraw the excess funds immediately
- Complete Form T3012A (for RRSP) or include info on RC243 (for TFSA)
- Explain your situation to CRA with a cover letter to request a waiver of penalties (they may accept if it was due to reasonable error)
📋 Example: RRSP Overcontribution Scenario
Suppose you had $25,000 in RRSP room and contributed $29,000. Your overcontribution is $4,000. CRA will allow the first $2,000 without penalty, but you’ll pay 1% tax on the remaining $2,000 every month until corrected.
📋 Example: TFSA Overcontribution Scenario
If you had $6,000 TFSA room and contributed $9,000, your overcontribution is $3,000. CRA will apply a 1% monthly tax on the $3,000 until it’s withdrawn. Even if you withdraw after 2 months, you’ll owe $60 in tax plus potential interest and penalties.
