Which deposits count against which year

A TFSA counts a plain calendar year. An RRSP does not: a contribution in the first 60 days of a year can be applied to the previous year’s deduction limit, which is when most Canadians contribute and is where most people measure the wrong year.

How it works out the window

For a TFSA the window is the calendar year, and the room you did not use carries forward indefinitely. Nothing is lost on 31 December. What happens on 1 January is that a new year’s room is added, and that a withdrawal made during the closing year is added back.

For an RRSP the window runs from the 61st day of the tax year to the 60th day of the year after it. That second date is a real deadline: a contribution after it cannot be deducted on that year’s return. The 60th day is counted rather than assumed to be 1 March, because in a leap year it is 29 February. CRA also treats a contribution made on the next business day as on time when the 60th day falls on a weekend, and that shift is not modelled here.

This is the same rule the Luum Tax Centre applies, and pnpm guard:room-agrees fails the build if this page and the product ever disagree about which year a deposit belongs to.

What this deliberately does not do

It does not work out your room for you. Your room depends on withdrawals in earlier years, years before you turned 18, any year you were not resident, your pension adjustment and your carry forward. CRA’s figure accounts for all of that and an arithmetic guess does not, in the direction that tells you there is room when there is not. Take the number from CRA My Account or your notice of assessment.
It publishes no contribution limit. The annual figures and the over-contribution rules are on TFSA and RRSP contribution room, which is checked against every other page that states them. One page owns a figure; the rest link to it.
It does not know about your other accounts. Room is measured per taxpayer, so a second TFSA at another institution shares the same room. Enter every deposit, wherever it was made.
It is not a substitute for CRA. An over-contribution is worth confirming with them rather than with a web page, and this is educational rather than advice.

Educational only, and accurate to what you enter. For how Luum tracks deposits across every connected account and warns before a limit is crossed, see the Tax Centre.
