What Income is Used to Calculate GIS in Canada?
The Guaranteed Income Supplement (GIS) is a Canadian federal government program designed to provide additional monthly financial assistance to Old Age Security (OAS) pensioners who have low incomes. Understanding precisely what income is used to calculate GIS in Canada is crucial for seniors to maximize their potential benefits. Service Canada uses a specific calculation based on your adjusted net income from the previous tax year, which is derived from your T1 General Income Tax and Benefit Return.
Who Should Use This Information?
- Canadian residents aged 65 or older who receive OAS.
- Individuals whose annual income falls below a certain threshold, which varies by marital status and number of dependent children.
- Seniors who want to understand how their income sources impact their eligibility for financial aid.
Common Misunderstandings:
A frequent point of confusion is the difference between your total Net Income (Line 23600 on the T1 General) and your GIS Income. While Net Income is the starting point, Service Canada allows specific deductions to arrive at the GIS-calculated income. Forgetting these deductions can lead to an overestimation of your income and, consequently, a lower GIS benefit than you might be entitled to. For example, income from sources like the Universal Child Care Benefit (UCCB) is included in your Net Income but is not deductible for GIS purposes, whereas Registered Pension Plan (RPP) contributions are deductible.
Key Takeaway: GIS is calculated on an adjusted net income figure, not your gross income or even your total net income directly. Specific deductions are permitted to arrive at this figure.
GIS Income Formula and Explanation
The core of determining GIS eligibility lies in calculating your GIS Income. This figure is generally derived from your annual net income, with certain income sources excluded and certain expenses deductible.
The Basic Formula
The fundamental formula Service Canada uses is:
GIS Income = Net Income (Line 23600) – Allowed Deductions
It’s important to note that “Allowed Deductions” are specific items permitted by Service Canada, not all possible tax deductions. For GIS purposes, income such as OAS benefits and GIS itself are not counted towards the income used for calculation. However, they are considered in the context of your overall financial situation for determining the *amount* of GIS you receive.
Variables Explained
| Variable | Meaning | Source on T1 General (if applicable) | Deductible for GIS? | Typical Range (Annual) |
|---|---|---|---|---|
| Net Income | Total income after most deductions. | Line 23600 | Base figure; deductions are subtracted from this. | $0 – $70,000+ (varies greatly) |
| Allowed Deductions | Specific expenses and income types that reduce the Net Income figure for GIS calculation. | Various lines (e.g., 20700, 21900, 21400, 22000, 22215, 21200) | Yes (if applicable) | $0 – $15,000+ (highly variable) |
| GIS Income | The adjusted income figure used by Service Canada to determine GIS eligibility and amount. | Calculated by Service Canada | N/A | $0 – $50,000+ (varies greatly) |
| Registered Pension Plan (RPP) Contributions | Contributions made to a registered pension plan. | Line 20700 | Yes | $0 – $5,000+ |
| Moving Expenses | Deductible expenses incurred due to a move for work or study. | Line 21900 | Yes | $0 – $2,000+ |
| Child Care Expenses | Expenses paid to allow work or study. | Line 21400 | Yes | $0 – $10,000+ |
| Support Payments Made | Payments made under a court order or agreement. | Line 22000 | Yes | $0 – $12,000+ |
| CPP/QPP Contributions | Mandatory contributions to the Canada/Quebec Pension Plan. | Line 22215 | Yes | $0 – $3,700+ (max contribution) |
| Employment Insurance (EI) Premiums | Premiums paid for EI coverage. | Line 21200 | Yes | $0 – $1,000+ (max premium) |
| Universal Child Care Benefit (UCCB) | A taxable benefit paid to families with young children. | Line 11700 | No | $0 – $2,300 per child/year (older program, now CCB) |
Practical Examples
Let’s illustrate how different income scenarios affect the GIS Income calculation.
Example 1: Single Senior with Moderate Income
Scenario: Ms. Evelyn Reed, a single senior, had the following figures on her last T1 General:
- Net Income (Line 23600): $32,500
- RPP Contributions (Line 20700): $4,000
- Moving Expenses (Line 21900): $0
- Child Care Expenses (Line 21400): $0
- Support Payments Made (Line 22000): $0
- CPP/QPP Contributions (Line 22215): $0 (as she is retired and over 70)
- EI Premiums (Line 21200): $0
- Other Deductible Income: $0
Calculation:
GIS Income = $32,500 (Net Income) – $4,000 (RPP Contributions) = $28,500
Ms. Reed’s GIS Income is $28,500. This lower figure compared to her Net Income increases her chances of qualifying for a higher GIS benefit amount.
Example 2: Senior Couple with Pension Income and Deductions
Scenario: Mr. and Mrs. Chen, a married couple, file taxes jointly but their GIS eligibility is assessed individually based on their respective incomes. Let’s focus on Mr. Chen:
- Net Income (Line 23600): $45,000
- RPP Contributions (Line 20700): $6,000
- Moving Expenses (Line 21900): $1,200 (from a recent move for family)
- Child Care Expenses (Line 21400): $0
- Support Payments Made (Line 22000): $5,000 (to an adult child)
- CPP/QPP Contributions (Line 22215): $0
- EI Premiums (Line 21200): $0
- Other Deductible Income: $0
Calculation:
Total Allowed Deductions = $6,000 (RPP) + $1,200 (Moving) + $5,000 (Support) = $12,200
GIS Income = $45,000 (Net Income) – $12,200 (Total Deductions) = $32,800
Mr. Chen’s GIS Income is $32,800. This adjusted figure is used to assess his GIS eligibility. Mrs. Chen’s calculation would be separate, based on her own income and deductions.
Example 3: Income Included, Not Deductible
Scenario: Mr. David Lee received $1,500 in Universal Child Care Benefit (UCCB) payments, which are taxable and included in his Net Income (Line 23600). His Net Income before considering UCCB was $28,000, making his total Net Income $29,500.
Calculation:
Assuming no other deductions:
GIS Income = $29,500 (Net Income) – $0 (No deductions apply to UCCB) = $29,500
Even though UCCB is a benefit payment, it is counted towards his income for GIS calculation and cannot be deducted.

Key Factors That Affect GIS Income Calculation
Several factors significantly influence the calculation of your GIS Income, impacting your eligibility and the amount of benefit you receive. Understanding these can help you plan financially.
- Net Income (Line 23600): This is the foundation. Higher net income generally leads to a higher GIS Income, potentially disqualifying you or reducing your benefit. It includes most forms of income, including employment, self-employment, pensions, investments, and taxable benefits.
- Registered Pension Plan (RPP) Contributions: Contributions to a workplace pension plan are deductible. The higher your RPP contributions, the lower your GIS Income will be, which is advantageous for GIS.
- Spousal/Partner Income: For couples where both are 65+, GIS is calculated individually. However, certain income-tested benefits (like the Allowance for the Survivor) consider combined income. For GIS purposes, it’s your individual income after deductions.
- Deductible Moving Expenses: If you moved for work or to attend a post-secondary institution, these expenses can be deducted, lowering your GIS Income. The deduction has limits and specific eligibility criteria.
- Child Care Expenses: Payments made to allow you or your spouse/partner to work, train, or look for work can be deducted. This directly reduces your GIS Income. The deduction is typically claimed by the lower-income spouse/partner.
- Support Payments Made: Court-ordered or legally mandated support payments made to a former spouse, common-law partner, or child are deductible. This can significantly reduce your GIS Income.
- CPP/QPP and EI Premiums: Mandatory contributions to the Canada/Quebec Pension Plan and Employment Insurance are deductible. While the amounts are capped annually, they contribute to lowering your GIS Income.
- Taxable Benefits vs. Non-Taxable Benefits: Income sources that are non-taxable (like certain disability payments or veterans’ benefits) may not be included in Net Income and thus don’t affect GIS Income. However, taxable benefits like OAS and GIS itself are treated differently in the calculation process (OAS is counted, GIS isn’t).
Frequently Asked Questions (FAQ)
-
Q: Is GIS calculated on gross income?
A: No, GIS is calculated on your adjusted net income, which starts with your Net Income (Line 23600) but allows for specific deductions. -
Q: Can I deduct my OAS pension income when calculating GIS Income?
A: No, your OAS pension income is generally included in your Net Income (Line 23600) and is not deductible for GIS calculation purposes. However, OAS income itself is not counted towards the income used to determine the *amount* of GIS you receive. -
Q: What happens if my spouse has income?
A: GIS is typically calculated based on each individual’s income. For couples where both partners are 65+, their respective net incomes and deductions are used to determine their individual GIS amounts. The Allowance and Allowance for the Survivor are income-tested benefits that consider combined income. -
Q: Are investment income gains (like dividends or capital gains) considered for GIS?
A: Yes, taxable investment income, including dividends and capital gains realized, is generally included in your Net Income (Line 23600) and therefore affects your GIS Income calculation. -
Q: How do I find my “Adjusted Net Income” for GIS?
A: Service Canada calculates this figure based on your T1 General tax return. You can estimate it using our calculator by inputting your Net Income and all applicable deductions. -
Q: What if I had significant medical expenses? Are they deductible for GIS?
A: Medical expenses themselves are not directly deductible for GIS calculation. However, they can be claimed as a tax credit on your income tax return, potentially reducing your overall tax payable, which might indirectly help your cash flow. They do not reduce your Net Income (Line 23600) for GIS purposes. -
Q: Does the year I report matter?
A: Yes, GIS is calculated based on your income from the previous calendar year. For example, the GIS benefits you receive in July 2024 to June 2025 are based on your income reported for the 2023 tax year. -
Q: Can I appeal Service Canada’s GIS income calculation?
A: Yes, if you disagree with Service Canada’s calculation of your GIS income or benefit amount, you have the right to request a reconsideration or appeal the decision through the established Service Canada processes.
