AFNI explained for 2026
AFNI explained in plain language for 2026: it's the single number CRA uses to decide how much your family gets. Canada Child Benefit, CGEB, and most provincial child supplements all run on it. Get the number right and the federal cheque is right. Get it wrong and you're either overpaid (and owe it back) or underpaid (and missing money).
The good news: AFNI is one of the simpler tax-line calculations in the Canadian system. The definition has barely changed since the Income Tax Act first wrote it in s. 122.6. The bad news: it's still mis-stated in half the personal-finance articles online. They conflate it with “net income” or “taxable income” or “AGI” (a US term that doesn't exist in Canada).
This page walks the actual definition with the actual line numbers from your 2025 tax return. The calculator on this site uses AFNI as its master input.
TL;DR: AFNI = both spouses' net income (line 23600 each) minus UCCB and RDSP repayments plus UCCB and RDSP amounts received. For most Canadian families that boils down to: spouse A income + spouse B income − RRSP contributions − support paid + support received. RRSP is the single most powerful lever to lower AFNI and raise CCB.
Quick answer: what AFNI is and why it matters in 2026
AFNI stands for Adjusted Family Net Income. It's defined in the Income Tax Act s. 122.6 and used by CRA to calculate every benefit that's income-tested at the family level. That includes:
- Canada Child Benefit (CCB)
- Canada Groceries and Essentials Benefit (CGEB, formerly the GST/HST credit)
- All 13 provincial and territorial child benefits (OCB, BCFB, ACFB, Allocation famille, etc.)
- Child Disability Benefit (CDB)
- Canada Workers Benefit (CWB) at the family rate
The CCB phase-out for 2026-27 kicks in at AFNI $38,237 for a 2-kid family. Above that the per-kid CCB drops at 7-23% per dollar depending on how many kids you have. CGEB phases out at 5% above ~$46,500 AFNI. Every $1,000 you shave off AFNI is worth $135 in CCB and $50 in CGEB for a typical 2-kid Tier 1 family. Paid yearly, tax-free.
AFNI is the master variable. The benefit math is downstream of it. That's why the calculator on this site reports your AFNI prominently in the headline. It's the input that drives everything else.
The AFNI formula in plain language
The full ITA 122.6 definition reads:
AFNI = spouse_A_net_income (line 23600)
+ spouse_B_net_income (line 23600)
− UCCB_repayment_in_year
− RDSP_income_received_in_year
+ UCCB_lump_sum_received_in_year
+ RDSP_income_repaid_in_yearFor most Canadian families, the UCCB and RDSP lines are zero. UCCB was replaced by CCB in 2016. RDSP is for disability savings. So the practical formula is:
AFNI = spouse_A_net_income + spouse_B_net_incomeWhere each spouse's net income (line 23600 on the T1) is:
net_income = total_income (line 15000)
− RRSP_contributions
− union_dues
− child_care_expenses_paid (Form T778, deducted by lower earner)
− moving_expenses
− support_paid (deductible alimony / child support)
− employment_expenses
+ support_receivedSo if you want to estimate your AFNI in 60 seconds: take each spouse's gross income, add any other taxable income (rental, investments), subtract RRSP contributions, subtract any deductible support paid, add any support received. Sum both spouses' results to get your AFNI.
The calculator on this site does this automatically using the seven inputs in the advanced mode.
What counts and what doesn't in AFNI
The most common questions about what counts in AFNI break down to three lists.
Counts (raises AFNI):
- Employment income (salary, wages, bonuses)
- Self-employment net income (after business expenses)
- Investment income (interest, dividends, capital gains)
- Rental income
- EI parental benefits (yes, these count)
- Pension income (CPP, OAS, employer pension)
- Quebec parental insurance (QPIP)
- Other taxable income (royalties, awards)
- Support received (alimony / spousal support paid TO you)
Doesn't count (no effect on AFNI):
- CCB itself (it's tax-free)
- CGEB (also tax-free)
- Provincial child benefits (tax-free)
- TFSA withdrawals (tax-free)
- GST/HST credit (it's a federal transfer, not income)
- Gifts and inheritances
- Lottery winnings
- Capital gains on principal residence
- Most non-taxable scholarships
Lowers AFNI (deductible):
- RRSP contributions (dollar-for-dollar)
- Union and professional dues
- Child care expenses (Form T778, claimed by lower-earning spouse)
- Moving expenses (for work or school)
- Support payments paid (deductible alimony)
- Employment expenses (T2200 form required from employer)
The two biggest practical AFNI-lowering moves for most Canadian families are RRSP contributions and Form T778 child care expenses. The T778 must be claimed by the lower-earning spouse.
RRSP contributions lower AFNI dollar-for-dollar
The single most powerful CCB-boosting lever in Canada is the RRSP. Every $1,000 contributed to an RRSP lowers your line 23600 net income by $1,000, which lowers AFNI by $1,000, which raises CCB.
For a 2-kid family in the CCB Tier 1 range ($38,237 to $82,847 AFNI), each $1,000 of RRSP contribution adds $135/year in CCB. That's on top of the tax refund of about $250-$400 at middle income.
Total effective return on a $1,000 RRSP contribution for a middle-income 2-kid family: $385-$535, paid back in the same year. Plus the $1,000 grows tax-deferred inside the RRSP for the next 30+ years.
This is the math that family-finance advisors flag as the most under-used Canadian lever. TFSA doesn't reduce AFNI. RRSP does. For families with kids under 18, the AFNI impact alone is a strong reason to pick RRSP over TFSA during the high-CCB years.
The spousal RRSP works the same way for single-income households. The working spouse contributes to a spousal RRSP using their own room. The contribution still reduces AFNI by the full amount (it's the contributing spouse's deduction). At retirement, the withdrawals are taxed in the stay-home spouse's hands at their lower rate. The household captures both the tax deferral and the income-splitting benefit.
A worked example: calculating AFNI for a typical Canadian family
Concrete numbers. Toronto family, both spouses working, two kids under 6.
Spouse A 2025 tax return:
- Line 10100 (employment income): $85,000
- Line 12700 (capital gains): $2,000 (taxable portion)
- Line 15000 (total income): $87,000
- Line 20800 (RRSP deduction): $8,000
- Line 22900 (union dues): $700
- Line 21400 (child care expenses, T778): $0 (claimed by spouse B since spouse B has lower income)
- Line 23600 (net income): $78,300
Spouse B 2025 tax return:
- Line 10100 (employment income): $55,000
- Line 12100 (interest income): $500
- Line 15000 (total income): $55,500
- Line 20800 (RRSP deduction): $3,000
- Line 21400 (child care expenses, T778, lower earner): $15,000 (full $7,500 per kid for 2 kids in licensed daycare)
- Line 23600 (net income): $37,500
AFNI for the family:
- Spouse A line 23600: $78,300
- Spouse B line 23600: $37,500
- No UCCB or RDSP adjustments
- AFNI: $115,800
For 2026-27 benefit year (using 2025 tax data), this family's CCB calculation runs on $115,800 AFNI. That's past the Tier 1 threshold of $38,237 and within Tier 2 ($82,847+). Net CCB for 2 kids under 6 at $115,800 AFNI: about $8,920/year, or $743/month.
Note how much the T778 child care deduction helped here. Without it, spouse B's net income would be $52,500 and AFNI would be $130,800. CCB at that higher AFNI would be about $7,990/year. The T778 deduction was worth about $930/year in extra CCB, on top of the regular tax savings.
Where AFNI shows up on your tax return
AFNI doesn't have its own line on the T1 return. It's calculated by CRA from your filed return after assessment. You can find your AFNI in two places:
Your CRA My Account.Log in to canada.ca, navigate to “Benefits and Credits,” click on “Canada Child Benefit.” The “income used to calculate” line on the most recent CCB notice is your AFNI for the current benefit year.
Your CCB notice (mailed each July).CRA sends a CCB notice every July showing the new benefit-year amounts. The “your family income for [year]” line on that notice is your AFNI.
You can also calculate it yourself before CRA assesses your return. Add both spouses' line 23600 from your draft returns. The result is your projected AFNI for the next benefit year.
Most Canadian tax software (TurboTax, Wealthsimple Tax, StudioTax) computes AFNI behind the scenes when both spouses file. Some show it explicitly; others bury it in the family-benefits estimator.
Why AFNI matters for CCB, CGEB, and the provincial benefits
Every federal child benefit and most provincial child benefits use AFNI as the input. The phase-out math runs differently per program but the input is always AFNI.
- CCB: Tier 1 starts at $38,237 (2 kids), Tier 2 starts at $82,847. Phase-out rates 7-23% per dollar.
- CGEB: Phases out at 5% per dollar above ~$46,500 AFNI.
- CDB (Child Disability Benefit): Phases out at 3.2-5.7% per dollar above $82,847 AFNI.
- Ontario Child Benefit: 8% per dollar above $26,865 AFNI.
- BC Family Benefit: Linear interpolation between $29,526 and $94,483 AFNI.
- Alberta ACFB: Phases out above $28,116 (base) and $47,115 (working component) AFNI.
- Quebec Allocation famille: Linear interpolation between $60,000 and $107,000 AFNI for two-parent families.
All of these run off the same AFNI input. So a $1,000 reduction in AFNI through an RRSP contribution helps your family across all six programs simultaneously, not just one.
This compounding is why RRSP contributions for families in the Tier 1 range can return more than 50% in the same year. The federal CCB bump, the CGEB bump, the provincial supplement bump, and the regular tax refund all stack on the same $1,000 deposit.
Frequently asked questions
What is AFNI in Canada?
Adjusted Family Net Income. The single number CRA uses to calculate every income-tested federal and provincial child benefit. Defined in ITA s. 122.6. Practical formula for most families: spouse A line 23600 + spouse B line 23600. Line 23600 is total income minus RRSP, union dues, child care expenses, and support paid, plus support received.
How do I calculate my AFNI?
Take each spouse's line 23600 (net income) from their T1 return and add them together. Line 23600 is gross income minus RRSP contributions, union dues, child care expenses (T778), and deductible support paid, plus support received. The sum of both spouses' line 23600 is your AFNI.
Does RRSP reduce AFNI?
Yes, dollar-for-dollar. Every $1,000 of RRSP contributions lowers line 23600 by $1,000, which lowers AFNI by $1,000. For a 2-kid family in the CCB Tier 1 range, that's about $135/year in extra CCB plus the regular tax refund of $250-$400. RRSP is the most powerful lever Canadian families have to lower AFNI and boost CCB.
Is AFNI the same as net income?
No, but it's close. Net income is per-spouse (line 23600). AFNI is the family-level sum of both spouses' net income, with UCCB and RDSP adjustments layered on if applicable. For most modern Canadian families (post-2016, when UCCB was replaced by CCB), AFNI = spouse A net income + spouse B net income.
Where do I find AFNI on my tax return?
AFNI doesn't appear on the T1 itself. It's calculated by CRA after assessment. You can find it on your most recent CCB notice (mailed each July) or in CRA My Account under Benefits and Credits. To project it yourself before assessment, add both spouses' line 23600 from your draft returns.
Verdict on AFNI explained in 2026
AFNI explained in one line: it's the family's combined net income (both spouses' line 23600). It drives every federal and provincial child benefit Canada pays out.
For most Canadian families in 2026, the practical takeaways are simple. RRSP contributions are the most powerful AFNI-lowering lever (dollar-for-dollar reduction plus a tax refund on top plus a CCB boost). Form T778 child care expenses claimed by the lower-earning spouse is the second-most powerful. Other deductions (union dues, moving expenses, support paid) matter less but stack with the first two.
