Hiring Your Spouse in a Business
When a salary to your spouse is deductible, the payroll steps, the tax saving, and TOSI for corporations.
The short version
- You can deduct a salary paid to your spouse or common-law partner if they actually do work the business needs and the pay is reasonable for that work.
- The salary has to be really paid (not just recorded), run through payroll with income tax and CPP deducted, and reported on a T4.
- Employment with a related employer is often not insurable for EI, unless the terms are what you'd give a stranger. Either way, CPP generally applies.
- The tax saving comes from moving income from your higher bracket to your spouse's lower one. On $30,000 of real work, that can be several thousand dollars a year.
- In a corporation, dividends to a spouse are caught by the tax on split income (TOSI) unless an exception applies, such as your spouse working in the business an average of 20 hours a week, or you being 65 or older.
Hiring Your Spouse in a Business
Plenty of small businesses are two-person operations where one name is on the sign and the other does the books, the scheduling, the invoices and the customer calls. If that work is real, paying for it is legitimate, and it can save the household real money. If the "work" is being married to the owner, CRA will notice. Here's how to do it properly.
The Three Conditions
- The work is necessary to earn business income. Bookkeeping, scheduling, sales, site work, admin, marketing. Not household chores, and not the occasional favour.
- The pay is reasonable. Roughly what you'd pay an outsider for the same hours and skill. A $70,000 salary for answering the phone twice a week won't survive a review.
- The pay is actually paid. Into your spouse's own account, by cheque or transfer, with records. Money that stays in a joint account "in spirit" is the weakest version.
CRA's own guidance applies the same test to spouses as to children: the work must be needed for the business, and the salary reasonable. Board and lodging you provide to your spouse isn't deductible.
What the Saving Looks Like
| Ontario, 2026, sole proprietor | Owner earns it all | Spouse paid $30,000 for real work |
|---|---|---|
| Owner's business profit | $90,000 | $60,000 |
| Owner's income tax | about $16,080 | about $7,880 |
| Spouse's income tax | $0 | about $2,450 |
| Household income tax | about $16,080 | about $10,330 |
That's roughly $5,750 a year less income tax, assuming your spouse has no other income. CPP stays roughly similar in total (you pay the employer share on your spouse's wage, and your own CPP drops), but your spouse now builds a CPP pension in their own name. Payroll also means your spouse has earned income for RRSP room. The numbers come from our 2026 rules engine and leave out the employer CPP deduction and any EI.
What would paying my spouse save?
Tell the assistant your profit, province, your spouse's other income and the work they do. It estimates a reasonable wage range, the household tax saving, and the payroll setup you need.
Payroll: What You Have to Do
- Open a payroll program account (an RP account on your business number).
- Deduct income tax and CPP from each pay, and pay the employer's CPP share. CPP generally applies to a spouse's salary whenever you're deducting it as a business expense.
- Decide on EI. Because you don't deal at arm's length, the job may not be insurable. It can be if the pay, hours, duration and importance of the work are what you'd agree with a stranger. If you're unsure, ask CRA for a CPP/EI ruling.
- Remit on time, usually by the 15th of the following month.
- Issue a T4 and file the T4 summary by the end of February.
The salary goes on line 9060 of your T2125, with your employer CPP. Keep timesheets or a log of duties, the pay records and proof of payment. See business recordkeeping requirements.
Partner, Not Employee?
If your spouse is a true co-owner, putting in money and making decisions, a partnership may fit better than a salary: each partner reports their share of profit. A partnership has its own rules: the income split must reflect what each partner contributes, and partnerships with more than a few members, or with corporate partners, may need to file a partnership information return. Talk to an accountant before you switch.
Corporations: Salary vs Dividends
A corporation can pay your spouse a salary on the same tests: real work, reasonable pay. Dividends are different. Since 2018, the tax on split income (TOSI) taxes many dividends paid to family members at the top personal rate, which wipes out the benefit. The main ways out for a spouse:
- Excluded business: your spouse is actively engaged in the business on a regular, continuous and substantial basis, generally an average of at least 20 hours a week, this year or in any five previous years.
- Excluded shares: your spouse is 25 or older and owns shares with at least 10% of the votes and value of a corporation that isn't a professional corporation and doesn't earn 90% or more of its business income from services.
- You're 65 or older: dividends to your spouse are generally excluded if they'd have been excluded in your hands.
TOSI is one of the more technical corners of Canadian tax; read CRA's guidance or get advice before you pay a dividend to anyone but yourself. More on corporations is on small business taxes, and how your own pay should be split on salary vs dividends.
Mistakes That Get Reversed
- A round annual salary "paid" by year-end journal entry with no money moving.
- Pay far above the market rate for the work.
- No payroll account, no CPP, no T4.
- A spouse with a full-time job elsewhere and a large salary from your business for evening admin.
- Duties nobody can describe when CRA asks.
If CRA reverses the salary, it comes back into your income, often with interest. If you're reassessed, see notice of reassessment: what to do. Paying your kids works the same way, with an age test; see paying your children from your business. One side effect: once your spouse has a salary, you'll likely lose the spouse or common-law partner amount. It's usually worth far less than the saving, but count it.
Return Check flags family wages without matching T4s or payroll, a common review trigger.
Paying Your Spouse Questions
Can I pay my spouse a salary from my business in Canada?
Yes, if your spouse does work the business needs, the pay is reasonable for that work, and you actually pay it through payroll with a T4.
Do I have to deduct CPP and EI from my spouse’s salary?
Income tax and CPP generally apply. EI may not apply, because employment with a related person is often not insurable unless the terms are similar to what you would agree with an unrelated person.
How much can I pay my spouse?
An amount that is reasonable for the work performed, roughly what you would pay an unrelated person with the same skills for the same hours.
Can my corporation pay dividends to my spouse?
It can, but the tax on split income usually taxes them at the top rate unless an exception applies, such as your spouse working in the business about 20 hours a week on average, owning excluded shares, or you being 65 or older.
Do I lose the spousal amount if I pay my spouse?
The spouse or common-law partner amount is reduced as your spouse’s net income rises, so a salary will usually reduce or eliminate it.
