Updated Checked by the Tax-Services.ca editorial team How we check
CRA PDOC is the Payroll Deductions Online Calculator, a free CRA tool that works out CPP, EI and income tax deductions from the pay you enter. It covers every province and territory except Quebec, where you use Revenu Quebec’s WebRAS program instead.
What does the CRA’s PDOC actually do?
You give it the details of a pay, and it returns the federal and provincial or territorial tax, the CPP or EI amounts, and the net figure. The CRA page says it handles the most common pay periods, weekly and biweekly among them, using exact salary figures. It sits at canada.ca/pdoc.
Rates on the page were updated for July 2026. If the pay date you enter is July 1, 2026 or later, the new provincial rates apply. That matters in places where a rate changed mid-year, and a pay date in June can give a different answer from one in July.
What should you know before you use it?
Three things come straight from the CRA page. The reliability of the result depends on the accuracy of what you enter. The printout isn’t an official statement of earnings, because a real statement needs information the calculator doesn’t include. And the CRA doesn’t keep your entries, though they stay in your session for up to 30 minutes of inactivity.
That last point is practical. Close the browser and clear the cache when you’re done, especially on a shared computer. The CRA page says information stored in your browser could be viewed by others.
We couldn’t capture the full list of input fields from the page, so we won’t guess at them. Open the tool and read what it asks for. Short and dull, but it’s the honest answer.
Which deduction rules sit behind the answer?
Behind PDOC are the CRA’s payroll formulas, published as T4127, and the lookup tables, T4032, for each province. The formulas had a 122nd edition for January 1, 2026 and a 123rd for July 1, 2026. Here are the 2026 federal contribution figures we hold for an employee.
| Deduction | Rate | Applies up to | Yearly maximum |
|---|---|---|---|
| CPP | 5.95% above $3,500 | $74,600 | $4,230.45 |
| CPP second tier | 4% | $85,000 | $416 |
| EI outside Quebec | 1.63% | $68,900 | $1,123.07 |
Those limits explain why a pay stub changes late in the year.
Once you pass a maximum, that deduction stops and take-home pay rises, which is a pleasant surprise for higher earners in November and December and a non-event for everyone else.
How close is a calculator to the PDOC result?
Try an Ontario worker paid $2,884.62 every two weeks, which is about $75,000 a year. The payroll deductions calculator shows federal tax of $317.64, Ontario tax of $171.00, CPP of $163.33 and EI of $43.20. Net pay is $2,189.46.
Close, but not identical. Your PDOC answer may differ by a few dollars, because payroll systems spread tax across the year in steps. We haven’t run the CRA tool for this case, so treat ours as an estimate. For BC, be careful. The CRA moved to a different payroll rate from July, so an annual-return calculator and a July pay stub won’t agree exactly.
What if you’re not an employer?
Employees use the same idea in reverse. Your pay stub should match roughly what a tool shows for your gross pay. If it’s far off, check your TD1 forms first, since claim amounts change withholding. The take-home pay calculator gives a yearly view, and the net to gross calculator works backward from the pay you want.
Employers who remit these amounts can pair PDOC with the payroll remittance calculator, which covers the employer side. Employer duties go well beyond what any calculator covers, and the details fill a whole CRA guide. If you run payroll for staff, read the CRA’s employer guide.
Where do these numbers come from?
The PDOC description comes from the CRA’s Payroll Deductions Online Calculator page on canada.ca. The CPP and EI figures come from the CRA’s 2026 rates pages, and the example from the calculator on this site. This website has no connection with the CRA or any government body.
