RRSP Contribution Room: Carry Forward, the Pension Adjustment, and the Penalty for Going Over

Almost everyone knows there is a limit and almost nobody knows what theirs is. The number gets treated like a rumour: something a colleague mentioned, a figure from a newspaper, a percentage half remembered from a conversation with a bank. And the consequences of getting it wrong run in both directions. People contribute less than they could because they think the annual maximum is their limit, when unused room from earlier years may have been accumulating quietly for a decade. Other people contribute more than they have, discover it two years later, and find that a penalty has been running at one per cent a month the entire time. Neither of those is a complicated problem. Both come from not knowing one number that is printed on a document the government sends every year. This article explains how the number is built, why a workplace pension changes it, what happens when it is exceeded, and where to read your own.

How the room is actually built

Your deduction limit for a year is a running balance rather than an annual allowance, and it is assembled like this. Start with the unused room you had at the end of the previous year. Add this year’s new room, which is the lesser of 18 per cent of your earned income from the previous year and an annual maximum set by the Canada Revenue Agency. Subtract your pension adjustment if you have one. Add back any pension adjustment reversal, and subtract any net past service pension adjustment.

Two features of that formula matter more than the rest. The first is that the percentage is applied to last year’s earned income rather than this year’s, which is why the room available to a person who has just had their best year ever does not reflect it until the following year.

The second is that unused room carries forward indefinitely. It does not expire, it does not shrink, and it accumulates in silence. That is why somebody who has been paying down a mortgage and raising children for twelve years may have a limit large enough to change their planning entirely, and may have no idea.

The annual maximum is not printed here because it is reset every year and any figure on a page like this is out of date within twelve months. It is on the Canada Revenue Agency website, and, far more usefully, your own limit is printed on your notice of assessment and shown in your CRA account.

The pension adjustment, and why it is not a penalty

If you belong to a registered pension plan or a deferred profit sharing plan at work, your employer reports a pension adjustment each year, and it reduces your RRSP room for the following year. People often read that as being punished for having a pension, and that is not what is happening.

The tax system allows a broadly comparable amount of tax assisted retirement saving to everyone, whether it accumulates in a personal account or in a workplace plan. The pension adjustment is the mechanism that measures what the workplace plan provided so the total stays comparable. A person with a generous defined benefit pension will have very little RRSP room, and that reflects the fact that a substantial retirement benefit is already being accumulated on their behalf.

A pension adjustment reversal appears when someone leaves a plan before the benefit fully vests, restoring room that was subtracted for a benefit not ultimately received. It is worth knowing about because it usually arrives in the year after leaving a job, when nobody is thinking about contribution room, and it can be substantial.

Going over, and what it costs

There is a cushion. Contributions that exceed your deduction limit by up to $2,000 are not penalised, though the excess is not deductible either. Beyond that cushion, a tax of 1 per cent per month applies to the excess for each month it remains in the plan.

One per cent per month deserves to be read carefully rather than skimmed, because on an annual basis it is a rate that will consume a meaningful share of the amount involved, and it continues month after month until the excess is removed or absorbed by new room. A person who over contributes and does not notice for two years has paid it for twenty four months.

The remedy is to withdraw the excess promptly, and there is a process for it, including a form that reports the excess and a mechanism for withdrawing unused contributions. That is work for a qualified tax professional rather than something to improvise, and the important part is speed, because the tax accrues monthly while the situation is being sorted out.

How it happens is worth naming, because it is almost never carelessness. Automatic monthly contributions set up years ago and never revisited. A group plan at work contributing alongside personal contributions. A spousal plan where both spouses are contributing without coordinating, since spousal contributions use the contributor’s room. A bonus directed to an RRSP by an employer on top of what the employee was already doing. All four are preventable by looking at one line on one document once a year.

The two deadlines

The first is the annual contribution deadline for a contribution to be deductible against the previous tax year, which falls in the first sixty days of the following calendar year. The exact date shifts with weekends and is published by the Canada Revenue Agency each year.

The second is the one nobody plans for: 31 December of the year you turn 71 is the last day you can contribute to your own RRSP. After that the plan has to be dealt with, by transferring it to a registered retirement income fund, purchasing an annuity, or taking it into income, which is almost never the right answer.

A person who turns 71 and has a younger spouse retains one option worth knowing about: contributions to a spousal plan can continue while the contributor still has room, based on the younger spouse’s age. That is a planning point that arrives exactly once and is easily missed.

Contributing and deducting are two different decisions

This is the point that most improves outcomes and is least often explained. Contributing to an RRSP and deducting the contribution are separate actions. A contribution can be made this year and the deduction claimed in a later year, and the amount grows sheltered in the meantime.

That matters because the value of a deduction depends on the tax rate it is applied against. Someone early in a career, or in an unusually low income year, may be better served by contributing now, letting the money grow, and carrying the deduction forward to a year in a higher bracket.

It also matters in the other direction. Someone whose income will fall permanently, or who expects to be subject to income tested recoveries in retirement, may find that the deduction is worth more now than the withdrawal will cost later, or the reverse. It is a genuine calculation rather than a rule of thumb, and it is a conversation with a qualified tax professional.

Earned income, the term the whole formula turns on

The percentage in the formula above is applied to earned income, and earned income is a defined term rather than a polite way of saying what you made last year. Reading it as the second thing produces two opposite errors, and both are common.

What generally counts is income that comes from working. Employment income. Net income from a business carried on alone or as a partner. Net rental income from real property. Royalties on your own work. Certain support payments that are included in income. Some disability payments from the Canada Pension Plan or the Quebec Pension Plan count as well.

What generally does not count is income that arrives without work. Interest and other investment income. Capital gains. Most pension income. Withdrawals from a registered plan. That list explains an outcome that catches a household every year: a person who has retired and lives on a portfolio builds no new room at all, however large the income is, and neither does a person who sells a business for a substantial gain.

The surprise runs the other way too. Net rental income creates room. A modest self employment income earned alongside a salary creates room on top of the salary. And losses reduce the figure, because the term is a net one.

The definition has details and exceptions, and the Canada Revenue Agency publishes it. Read it there, and take your own calculation to a qualified tax professional.

When money comes out and goes back in

Two federal programs let money leave a plan without being taxed on the way out, on the condition that it goes back in: the Home Buyers’ Plan and the Lifelong Learning Plan. Both touch contribution room, and the way they touch it is the opposite of what most people assume.

A withdrawal under either program does not restore room. The room was consumed when the contribution was made, and taking the money out again does not hand it back.

A repayment does not use room either, and this is the half that goes wrong. A repayment has to be designated as a repayment on the return. Designated correctly, it is neither deductible nor charged against the limit. Not designated, the same deposit becomes an ordinary contribution: it uses room the person may not have, it may be deducted when it should not be, and the repayment they believe they made is still outstanding.

What follows is mechanical rather than punitive. An amount not repaid for a year is added to income for that year. Nobody is fined and there is nothing to argue about: the system treats the missing repayment as a withdrawal and taxes it as one.

The designation is a line on a form, which is why it is worth walking through with a qualified tax professional in the first repayment year, once. The article on both programs sets out how the repayment schedules work.
