Estimated net tax owing ($4,221.33) exceeds the $3,000 CRA instalment threshold. Instalments usually apply only if a prior year also exceeded the threshold — budget about $1,055.33 per quarter (Mar/Jun/Sep/Dec 15) for planning. Confirm with CRA My Account.
Per CRA Schedule 8: only the employee half of base CPP/QPP is a non-refundable credit; the first additional and CPP2/QPP2 amounts on self-employment are deductible (line 22200).
Canada self-employed tax for 2026 is estimated from net business income (turnover − expenses), then federal and provincial income tax (same brackets and BPA credits as our Canada paycheck engine) plus self-employed CPP/QPP at double the employee rate. Per CRA Schedule 8: deduct the employer half of base CPP plus all first-additional and CPP2 amounts (line 22200); claim a non-refundable credit only on the employee half of base CPP (line 31000). EI is optional (voluntary special benefits).
