Build Canada Workers Benefit 2027: Proposed Amounts and Advance Payment Cut

Last verified: November 6, 2026

Budget 2026 proposes a new Build Canada Workers Benefit for the 2027 tax year. For a worker with very low earnings, the proposed formula could add as much as $675 compared with the Canada Workers Benefit rules that would otherwise apply in 2027. The maximum basic benefit would rise by $150 for a single person without children and by $200 for a family.

The trade-off is timing. Advance payments would shrink in July 2027 and disappear starting with the 2028 tax year. More of the benefit would arrive only after the worker files a tax return.

This measure is proposed, not in force. The budget includes a Notice of Ways and Means Motion with draft Income Tax Act amendments, but Parliament must pass legislation before the rules become law. The Canada Revenue Agency (CRA) has not yet published final 2027 administration details.

What Budget 2026 would change

The proposed basic benefit would still grow at 27 cents for each dollar of working income above the threshold. It would still be reduced by 15 cents for each dollar of adjusted net income above the applicable phase-out threshold. The lower phase-out thresholds keep the income level at which the benefit reaches zero essentially unchanged.

The budget’s affordability chapter estimates that 1.9 million low-income workers would receive a larger benefit and 180,000 people would become newly eligible. The government estimates the measure could increase the entitlement by up to $675 for workers with the lowest earnings, or by nearly $1,000 for someone who also qualifies for the disability supplement.

Worked examples show where the extra $675 comes from

These PaycheckGuru calculations use the standard federal 2027 parameters in the budget documents. They assume working income and adjusted net income are the same, no disability supplement, and no province- or territory-specific reconfiguration. Actual entitlement can differ with family status, a spouse’s income and the rules for the worker’s jurisdiction.

For the single worker earning $5,000, the current-law calculation is 27% × ($5,000 − $3,000) = $540. The proposed calculation is 27% × ($5,000 − $500) = $1,215. The $2,500 reduction in the entry threshold creates the $675 difference.

At higher earnings, the larger maximum matters more than the lower entry threshold. A family reaches the proposed $3,143 maximum once the phase-in calculation hits that ceiling. The final amount can then decline if adjusted family net income is above $30,731.

Advance payments would be cut before they end

Under current rules, eligible recipients automatically receive 50% of the previous year’s Canada Workers Benefit entitlement in three advance payments. Any remaining entitlement is calculated after the tax return for the current year is filed.

Budget 2026 proposes to reduce that advance to 25% for the 2027 tax year, beginning in July 2027. If a worker’s 2026 entitlement were $1,200, the proposed 2027 advance would total $300 instead of $600 under the current formula. That is a cash-flow reduction of $300 during the year. It is not necessarily a $300 loss of total benefit because the final 2027 entitlement would be calculated from the worker’s actual 2027 income after filing the return.

Starting with the 2028 tax year, advance payments would end. Eligible workers would receive the full benefit after filing. The budget says this change addresses advances that can exceed a worker’s eventual entitlement when income or family circumstances change. Current law does not require repayment of that excess.

The CRA’s current claim instructions still describe the existing automatic advance system. Do not use the proposed 2027 rules to forecast a payment date until the legislation passes and the CRA publishes its 2027 schedule.

Who could qualify

The budget changes the income formula, not the core description of an eligible worker. Under the CRA’s current Canada Workers Benefit eligibility rules, a claimant generally must earn working income, be a Canadian resident throughout the year, and be at least 19 by December 31 unless they live with a spouse, common-law partner or child.

Important exclusions currently apply. A person generally cannot claim the benefit if they were a full-time student for more than 13 weeks in the year without an eligible dependant, were confined to a prison or similar institution for at least 90 days, or did not have to pay Canadian tax because of diplomatic status.

Alberta, Quebec and Nunavut have reconfigured Canada Workers Benefit designs. Budget 2026 says province- and territory-specific reconfiguration agreements would continue. Readers in those jurisdictions should wait for the final CRA tables before treating the national examples above as their own amount.

What workers should do now

• Do not change a 2026 tax return or household budget yet. The proposal starts with the 2027 tax year and still requires legislation.
• File every year’s tax return. The current benefit is claimed on line 45300, and advance payments depend on a filed return.
• Plan for less money during 2027. If enacted as proposed, only 25% of the 2026 entitlement would be advanced beginning in July 2027.
• Check the final CRA tables. Family income, disability eligibility and provincial reconfiguration can change the result.

The proposed benefit would not directly change the deductions on a paycheque. It is a refundable tax credit calculated through the tax return. PaycheckGuru’s marginal-versus-average tax guide explains why a tax credit and a payroll tax rate are different. The site’s Canada Groceries and Essentials Benefit guide covers the separate quarterly benefit that Budget 2026 also proposes to top up in early 2027.

What remains unconfirmed

Parliament has not yet enacted the Build Canada Workers Benefit. The final legislation, CRA calculation tables, 2027 advance-payment dates and any province- or territory-specific parameters could change the practical result. This article will be reviewed when implementing legislation is introduced or the CRA publishes 2027 guidance.
