Quick answer
Home internet is claimable in Canada on both sides of the employment line. Employees use the detailed method: internet access fees at a reasonable employment share, on Form T777 with a signed T2200, having worked from home more than 50% of the time for at least four consecutive weeks. The self-employed deduct the business share on T2125. GST/HST follows the same percentage.
Is internet tax deductible in Canada?
Yes. For employees, home internet access fees are on the CRA’s list of eligible work-space-in-the-home expenses under the detailed method, which since 2023 is the only method: the pandemic-era $2-a-day flat rate is gone. The gate conditions do real work: a requirement to work from home (a formal or even verbal arrangement qualifies), more than 50% of working time at home for a stretch of at least four consecutive weeks, a completed T2200 from the employer, and no double-claiming of reimbursed amounts. What is claimable is the access fee at a reasonable employment share; equipment rental and connection fees are not.
The self-employed have the simpler path: the business share of the household connection is an ordinary T2125 expense, apportioned on a defensible usage basis. It travels with the business-use-of-home claim, but on its own logic: the house splits by floor area, the connection splits by who uses it and for what.
How much can you claim?
Employee worked example: an analyst worked from home three days a week from February through November, comfortably clearing the 50%-for-four-weeks test, with a signed T2200. Home fibre costs $80 a month. Her reasonable employment share, based on her hours and the household’s overall use, is 40%. The T777 claim for ten months is $80 x 10 x 40%, which is $320, alongside her other eligible home-office costs.
Self-employed worked example: a graphic designer running the studio from home puts the same $80 connection at 60% business by usage across the full year: $576 on T2125.
| Situation | Treatment |
|---|---|
| Employee, detailed method (T2200 + T777) | Employment share of internet access fees |
| Employee without T2200 or below the 50% test | No claim |
| Self-employed | Business share on T2125 |
| Equipment rental, connection fees (employees) | Not eligible |
| Reimbursed by employer | Excluded; employment-use reimbursement is not a taxable benefit |
GST/HST on internet costs
Self-employed registrants claim input tax credits on the business share at the provincial rate: 13% HST in Ontario, 5% GST in Alberta, GST plus QST in Quebec, and so on. Employees do not claim ITCs; a valid employment-expense claim instead supports the GST/HST rebate at line 45700, computed from the same eligible amounts. Keeping the percentage identical across the deduction and the tax recovery is the discipline that survives review.
Record-keeping requirements
Six years: the monthly bills, the signed T2200 (the CRA does not want it filed, but does want it kept), the calculation behind the employment or business share, and the record of weeks and hours that satisfied the 50% test. The four-consecutive-week qualifying period is the detail most people cannot evidence two years later; a calendar note at the time solves it.
How to claim, step by step
- Employees: confirm the qualifying conditions (requirement to work from home, 50% for four consecutive weeks) and get the T2200 signed.
- Set a reasonable employment or business share of the connection and write down the basis.
- Employees claim the share of access fees on T777, flowing to line 22900; the self-employed claim on T2125.
- Exclude reimbursed amounts, equipment rental, and connection fees for employee claims.
- Recover the tax: ITCs for registrants, the line 45700 rebate for employees.
- Keep bills, forms, and workings for six years.
Common mistakes
- Claiming under the abolished flat-rate method.
- No signed T2200 behind an employee claim.
- Claiming modem rental and installation as an employee.
- An internet percentage wildly out of line with the home-office claim with no explanation.
- Missing the line 45700 rebate that a valid employee claim earns.
