Spousal RRSPs For Income Splitting – From Diapers to Diapers

Most people think of Registered Retirement Savings Plans (RRSPs) as being for retirement. Duh, it’s in the name. However, for spousal RRSPs, some of the best uses are actually before you are old, wrinkly, and need the money to fund thirsty underwear purchases.

We previously did an overview of the basic anatomy of RRSPs. In this post we will focus on the specific features of spousal RRSPs, and strategies to use them to divert money from the government to fund your priorities rather than theirs.

Main Features of a Spousal RRSP

  • Contributions are made by a higher income spouse to a lower income spouse’s spousal RRSP.
  • The higher income spouse can deduct the contribution against their income, receiving a refund at their higher marginal tax rate. Be aware of reduced RRSP refunds from moving down tax brackets.
  • Investments in the RRSP grow tax-free (tax deferral).
  • Withdrawals are taxed as income in the hands of your lower income spouse (tax reduction).
  • Keep a spousal RRSP separate from that spouse’s personal RRSP to avoid difficulty with the attribution rules.

The attribution rules & spousal RRSPs.

  • If the lower income spouse withdraws the funds from their spousal RRSP when there has been any contribution in the previous two calendar years, then it is attributed back to higher income contributor and taxed at their higher marginal rate.
  • I underlined “any contribution” because this is a common point of confusion. For example, if you put some stocks into a spousal RRSP 10 years ago and put some bonds in last year and this year your spouse removes the stocks, then their value would still be attributed back to you and taxed in your hands.
  • The other point to remember is that it is by calendar year. If it is Nov/Dec and you are debating contributing now or waiting until Jan/Feb, then you may want to do it now to avoid needing to wait a whole extra year due to a two month delay. For example, you contribute $26K to a spousal RRSP in December 2017. In January of 2020, your spouse could withdraw the money as their own (a two year lag). If you had made the contribution in Jan of 2018 instead, they could not withdraw the money until January of 2021 without penalty (a three year lag).

The attribution rules limit our ability to use spousal RRSPs for short-term income splitting due to the 2-3 year lag, but they can be very useful for intermediate-term goals in four main ways:

  • To fund a low-income year, like a parental leave.
  • Increasing the amount of money that you can access from your RRSPs for the Home Buyer’s Plan.
  • Income splitting over a four-year cycle.
  • Evenly splitting retirement income if you retire before age 65.

Spousal RRSPs to Fund Parental Leaves

Professional couples have many advantages from an income standpoint. However, one major disadvantage that they do face is that neither parent usually have maternity/paternity benefits.

For physicians, many will start reproducing in residency which has the advantages of parental leave benefits coupled with the fertility prowess of youth. However, it also brings its own challenges combining the sleep deprivation of having small children with the demands of residency and licensing exams.

An Employment Insurance (EI) funded maternity leave also has long-term consequences.

An EI claim (including parental leave) means that they can never opt out of EI for the rest of their career if they are a sole proprietor or incorporated and pay salary. You may need to have a short career or multiple funded parental leaves to overcome this.

An important note: taking an EI parental leave while a resident (employee) dos not count. If you are self-employed and opt-in to EI and then take a parental leave, then it counts as an EI claim for your future as a self-employed person.

For those who plan to start or expand their families after residency, a spousal RRSP can help.

As long as they start planning a couple of years in advance. Let’s look at a case to illustrate…

Sherry and Thor Reproductive Case Study

Sherry is a medical student and hooks up with Thor, a hunky Viking-type who has his own business as a massage therapist (total score!). Their relationship blossoms, and having read the Quest for the One Ring, they find themselves to be financially compatible. They get married in the little hiatus between finishing med school and starting her surgical residency.

Their plan is to get Sherry’s residency and exams out of the way, and to establish her practice for a few years before having kids. She is concerned about de-skilling with time out of the OR and anticipates the many nights on call that come with the territory of being a surgeon.

Thor’s work is more flexible. He plans to work a lighter load when they eventually pop a baby out, and will largely be the stay-at-home dad for a year or two until it is easier to get daycare.

Spoiler alert – daycare for infants is really expensive and hard to find for people who work unsociable hours. Being proactive and financially savvy, they plan for the parental leave using a spousal RRSP.

Between Thor’s massage skills and exhaustion from Sherry’s residency, they don’t get out to spend too much money.

They max out their TFSAs and Sherry contributes 43K to a spousal RRSP for Thor over her five year residency. She read this blog, and doesn’t claim those deductions during residency because she knows she’ll be in a much higher marginal tax bracket as an attending very soon.

Sherry graduates and makes $400K her first year as a surgeon. She uses her carried forward RRSP deductions to get a 23K tax refund due to her 53.5% marginal tax rate.

Thinking that they may want to have kids in a couple years, Sherry stops contributing to Thor’s spousal RRSP. She wants to avoid the attribution rules which require two full calendar years of no contributions before a withdrawal.

A year and a half later, the biological clock starts ringing

Thor brings on the thunder, and nine months after that Sherry gives birth to their little demi-god. After two months, she heads back to work, relieved to be prescribing enemas again rather than dealing directly with the results. Changing diapers is not her thing.

Thor does the diapers and the occasional massage, bringing in $10K for the year. With their investment returns over the past 7 years, the spousal RRSP is worth $50K.

Thor draws that $50K from his spousal RRSP. His tax bill is ~11K for a net tax savings of ~$10K plus the $5K of growth from the RRSP. Sherry effectively shifted $50K from her 54% tax rate to her husbands 22% rate for a savings of $17K – that would buy a lot of diapers.

I used this example of a high earning physician with a lower earning self-employed spouse. However, it is applicable to numerous other situations. A lower-earning spouse may be employed with parental leave via Employment Insurance (EI) that pays up to ~28K. If this applied to Thor in the above example, they would still save ~14K by using this income splitting technique.

A spousal RRSP could also be drawn on for tax savings in a year where your spouse has a low-earning year due to job loss, illness, “finding themselves”, or some other unanticipated reason.

The main problem with using a spousal RRSP for a low-income year is that you have to have stopped contributions for two calendar years. So, it generally needs to be planned in advance.

Spousal RRSPs and the Home Buyer’s Plan

Owning a home is not a prerequisite for raising children. My parents rented the first few homes that I grew up in. However, it is often front and centre when the nesting instincts kick into high gear. A spousal RRSP can be accessed for up to $25K for the down payment on a first home. If the higher income spouse also has a personal RRSP, it can be accessed in addition, for a total of $50K between the couple.

Income-Splitting Over a Four Year Cycle Using a Spousal RRSP

If one spouse is well into the highest marginal rate and the other makes no income, then you could use a spousal RRSP in a four-year cycle.

In the first year, the high-income spouse (provided they have the contribution room) contributes three years worth of the max annual contribution. Then they don’t contribute for two calendar years to avoid attribution.

In the third calendar year, the low-income spouse can remove the money and it is taxed in their hands. Over those three years, the high-income spouse has accumulated another three years of contribution room and contributes that amount in the following year to repeat the cycle.

Using the 2018 Ontario tax rates, that would save $22K in tax over the four-year cycle for an average of $5575/year. It also has the advantage of giving the lower-income spouse income that is attributed solely to them. That means that it is investable in a personal account with the investment income taxed in their hands. More income-splitting.

I don’t personally know anyone who has used this strategy. There are some pros and cons.

It means more money in your hands in the near-term. It also increases the option for intermediate income splitting with a taxable personal investment account which could be helpful in a few specific cases.

However, this all comes at the cost of burning up your RRSP room which you cannot get back.

You will also note that when your spouse goes from no income to drawing on the RRSP, you lose the $2K spousal tax credit. If the high-income earner isn’t in as punitive a tax bracket as in this example, then that can cancel out much of the benefit.

That RRSP room could possibly be better used to shelter the tax-inefficient parts of your overall balanced portfolio (like bonds). That would allow them to compound tax-free over the longer-term instead. That is what we do personally.

We will likely be in a lower marginal tax rate when my wife and I access our RRSPs. My spouse also generates a decent income working for “The Corp” (that’s me). So, she is not in a super-low income bracket.

We also plan to retire well before age 65. So, the spousal RRSP plays an important intermediate-term income splitting role for us. If you are thinking of using this sort of cycling strategy, you should consult a financial planning professional to see how it fits as part of your comprehensive plan.

Spousal RRSPs to Income Split in an Early Retirement

When you are over the age of 65, you can split up to 50% of your pension or RRSP with your spouse. Even with the proposed changes to income splitting from a professional corporation, you should be able to give your spouse dividends from your CCPC after age 65. Income splitting becomes easy at that point.

However, if you plan on retiring or semi-retiring before age 65 , then spousal RRSPs may have a role.

It can help to evenly spread your retirement income draw between spouses to minimize the tax bite. The spouse can draw from their spousal RRSP while the incorporated professional get dividends from their corporation. To plan for this, you need to consider how much your retirement income will be and from what sources that income will be drawn by each partner.

Some factors to consider:

  • Does the lower-income spouse have a pension from work that kicks in before age 65? Income drawn from a spousal RRSP at the same time as a work pension could bump them up tax brackets.
  • Does the higher-income spouse have a pension from work that kicks in before age 65? If the lower income spouse does not have a pension, then this is a good case to build a spousal RRSP with whatever contribution room is left after the pension adjustment.
  • Will you be drawing on your personal and spousal RRSPs for income prior to age 65? There are different approaches about when to draw on RRSPs depending on your overall plan and income. Some may “melt down” their RRSPs early to avoid Old Age Security clawbacks. Others may defer drawing on their RRSPs until forced to at age 71. If you aren’t going to draw from your RRSPs before age 65, then a spousal RRSP doesn’t matter as much. As long as things work out as planned.

Are Spousal RRSPs Still Useful When You Get Really Old?… Depends.

For those trying to delay drawing from their RRSPs until as late in life as possible. A spousal RRSP may be of use.

If the higher-income spouse is older than the lower income spouse, then a spousal RRSP does not need to convert to a Registered Retirement Income Fund (RRIF) until that younger spouse turns 71.

Is there a role for a spousal RRSP in your financial plan?

Spousal RRSPs have been around for a long time as a method of income-splitting. Over that period, their utility has waxed and waned as the government changes the rules.

When RRSP/pension-splitting for those over 65 was introduced in 2007, many thought that this would end the utility of spousal RRSPs. In the hay-days of dispensing dividends to the spouse of an incorporated professional, they were also less popular. This may change with the new income-splitting rulesAs outlined in this post, there are a number of uses for the spousal RRSP to income split earlier in your life cycle.

At worst, I see the spousal RRSP as a “no lose” proposition if you are using RRSPs. At best, it gives you options.

Life often does not unfold entirely as planned due to children, health issues, an earlier retirement, or the government changing the tax rules. A spousal RRSP, as one plank in a multi-faceted financial plan, adds a layer of diversification against the risks of life and political risk. It is one of multiple ways to income-split and reduce your household tax bill.


  1. Similar to you, my plan is to “retire” well before the traditional retirement age of 65, so our spousal RRSPs play an important role in the deployment of our savings. However, I have not giving much thought as to when/how to withdrawal these funds, other than knowing about the the traditional RRIF withdrawal (my parents are just beginning this phase). The “cycling” strategy is interesting to learn about, and is good to know that it’s an option to use, if the appropriate scenario arises. Thanks for the post!

    1. I heard whispers of the cycling strategy from different advisors, but I still have not heard of anyone using it. Dividends from CCPCs made it unnecessary previously. Even with dividend income splitting gone, I think that with the cap on CCPC passive income that is coming up, having the RRSP room to shelter tax inefficient investments, like bonds, will likely be more important in the long run than a short-term tax savings that burns up RRSP room. Then again, giving your spouse more income to invest in their taxable account may be very valuable. It will likely depend on your portfolio size and mix, as well as your withdrawal plan. If you plan on having a high income in retirement and have large RRSPs, then they can become a tax liability if not handled properly. Especially if marginal rates keep rising -it wasn’t long ago that my marginal rate was in the mid 40s instead of the mid 50s. It is going to be interesting to see how the advisor community reacts to the upcoming changes. I suspect a multi-pronged approach and tax planning for the “exit strategy” becoming a much more prominent emphasis.

  2. Sorry for commenting on your old posts, but I had to dig this one up as RRSP season is coming and I was brushing myself up about spousal RRSPs. With the current tax laws and its new restrictions to income splitting with spouse from the corp, wouldn’t it make sense to direct RRSP capital 100% fully to the spousal RRSP instead (and not to self RRSP) moving forward? In this way, I could dividend myself from the corp in the future and spouse could have very low taxed RRSP income if we retire before 65, however, my own self RRSP would be burnt. From an income splitting perspective, it makes sense to me as a general strategy, but just want to hear your thoughts, thanks!

    1. Hi Mark,

      I am actually happy for comments on older posts. My plan is to intermittently update and refresh them rather than redo them.

      I think that you are exactly right. Prior to the hobbling of income-splitting, we were building a roughly equal RRSP for myself and my wife. Now, we are only building hers and her spousal RRSP. After age 65, it doesn’t matter. But, before then it gives us much more flexbility. If we want to or have to retire before then, scale back extensively or take a sabbatical, then I can use the corp while she uses her RRSP and we can bleed them down slowly to keep the taxes down.
