SeroPayroll: payroll for every province, right to the cent
Canadian payroll for all 13 provinces and territories — CPP, EI, QPP and QPIP, vacation pay, statutory holidays and overtime by each statute, remittances, T4s and Records of Employment. From $25 a month.
The pay run
Pay runs that cannot be paid twice
Calculate, approve, post, settle. Reverse rather than edit; bonus and off-cycle runs; weekly, bi-weekly, semi-monthly or monthly.
CPP, EI and income tax to the cent
CPP and CPP2, EI with Québec’s reduced rate, T4127 federal and provincial tax, QPP, QPP2 and QPIP, taxable benefits.
Benefits, deductions and garnishments
Applied in priority order, with a shortfall register when a cheque cannot cover them all.
Timesheets and time clock
Hours come straight from the clock into the pay run.
Employment standards
Vacation pay by the statute
Accrued and owed in dollars, the way each province defines it.
Thirteen holiday calendars
Statutory holiday pay computed with each jurisdiction’s own formula.
Overtime the way each statute writes it
Ontario’s 44 hours a week, Alberta’s 8/44 greater-of, BC’s daily two-tier plus weekly 40, and the rest.
Employer levies
Workers’ compensation, Ontario EHT, Manitoba’s HAPSE levy, Newfoundland and Labrador’s HAPSET and Québec’s HSF.
Remit and file
Remittances on the CRA’s calendar
PD7A for quarterly, regular and accelerated remitters, plus Revenu Québec TPZ-1015.
T4s that validate before they leave
T4 and T4 Summary XML, T4A, T5018 and RL-1 slips, with filing-readiness checks.
Records of Employment
ROE .BLK files for ROE Web, with the five-day deadline tracked.
PIER review
Catch CPP and EI deficiencies before the CRA’s Pensionable and Insurable Earnings Review does.
Stubs, cheques and bank files
Pay stubs with YTD and masked SIN, cheques, and CPA 005 direct-deposit files for RBC, TD, Scotiabank, BMO, CIBC and Desjardins.

Can SeroPayroll file T4s and ROEs?
SeroPayroll produces T4 and T4 Summary XML files that validate before you upload them to the CRA, plus T4A and T5018. It writes ROE .BLK files for ROE Web and tracks the five-day issuing deadline.
Does SeroPayroll do direct deposit?
It creates CPA 005 direct-deposit files for RBC, TD, Scotiabank, BMO, CIBC and Desjardins. You upload the file to your bank, which then pays your employees.
How does SeroPayroll relate to SeroBooks?
Payroll was built inside SeroBooks first and is still included in SeroBooks Pro. SeroPayroll is the same engine sold on its own, for businesses that want payroll without changing their accounting. The same login works on both.
