Is home internet tax deductible?
Partly. The share of your internet you use for the business is deductible, whether or not you claim a home office.
The rule
Internet at home is usually shared with the household, so you deduct the business share. Estimate it from the hours you work online against the hours the connection is used for anything else, and keep the estimate steady.
It is deducted on its own, not as part of the home office, so you can claim it even with no office. If you do claim the office under the regular method, don’t count the internet again in what the home costs.
A separate connection that only the business uses, in a studio or a rented office, is deductible in full.
An $80 monthly plan used half for work puts $40 a month on the return.
