How much TFSA room do you actually have?

Room starts in the year you turned 18 while resident in Canada for tax purposes — not in 2009. Getting this wrong costs 1 per cent per month, quietly, for years.

Your date of birth

Date of birth Age

Used only to work out the year you turned 18 — room does not start before then, no matter when you arrived. Nothing is sent anywhere.

Year you became a resident of Canada for tax purposes

For most newcomers this is the year you landed. If you were born here or arrived as a child, enter 2009 or earlier.

Total you have ever contributed

Every deposit ever made, across every institution. Not the current balance.

Withdrawn in previous years

Before this calendar year only. Money withdrawn this year does not restore room until 1 January — this is the mistake that costs people money.

Estimated room available

Enter both years to see an estimate.

Room accrued: $0

This is an estimate

The authoritative figure is in your CRA My Account, and it can lag by months if an institution has not reported a transfer yet. Check both, and if they disagree, trust the CRA and find out why.

Over-contributing costs 1 per cent of the excess per month, every month it remains.

How the TFSA works

Take this away as a PDF

A one-page summary of what you entered and what it works out to, built in your browser. Nothing is uploaded, and no copy reaches me unless you send it.

Your name (optional)

Printed on the document. Leave it blank and it prints without a name.

Annual limits verified against CRA publications on 2026-08-24.

Not sure which year you became a tax resident?

It is not always the year you landed, and it changes the number substantially. Worth twenty minutes to get right before you deposit anything.
