What records should a self-employed musician keep for home studio expenses?
Published · Updated · Clef
If you run a music business from home in Canada, keep room measurements, a record of business use, and the household bills that support your allocation. Check whether the workspace qualifies before estimating any deduction. A shared editing room needs evidence of both the space it occupies and the time you use it for business.
When can a home studio qualify as a business workspace?
For a Canadian sole proprietor, the CRA describes two ways a home workspace can qualify. It can be the main place you run your business. Otherwise, it must be reserved for earning business income and used regularly and on an ongoing basis to meet clients, customers or patients.
Start with a short description of where you do the work. A producer might edit client projects at home, track vocals at a rented studio and travel to a venue for occasional live sessions. Write down what happens at each location so your accountant can assess which is the main place of business. A room full of instruments does not establish how you use it. Employee expenses and corporate arrangements need separate review.
What should I measure and log in a shared room?
Draw a simple floor plan and label the workspace and total home area in the same units. Save the measurements behind both totals. If the setup changes halfway through the year, record when it changed and keep the earlier measurements so the reviewer can reproduce each period.
Keep a dated record of the room's business hours. Use calendar blocks or project logs to identify actual editing, remote client sessions and other work for the business. Keep personal practice and household use separate. If your schedule varies, use the available records to explain the pattern and flag periods you cannot substantiate. Do not count the entire day because a session took place in the room.
How would I document an irregular editing schedule?
Constructed example: a sole-proprietor producer uses a 12-square-metre room in a 96-square-metre home as a shared editing room. Assume for illustration that the home is the main place of business and that the logged pattern applies for the full billing period. The producer edits for clients for three hours on Monday and Wednesday and six on Saturday. The room is used personally at other times.
The area share is 12 divided by 96, or 12.5%. For this example the time share is 12 business hours across a 168-hour week. Applied together to an illustrative $140 electricity bill, the working allocation is $1.25. This shows the calculation under the stated assumptions. The reviewer still needs to confirm eligibility, which costs belong in the calculation, and whether the period is representative.
Save the week behind the arithmetic. If the producer stops taking projects for a month, the same weekly pattern should not be carried into that period without checking actual use.
| Record | Example | What it supports |
|---|---|---|
| Floor plan | 12 m² workspace in a 96 m² home | Area share |
| Work log | Three hours Monday, three Wednesday, six Saturday | Business time and personal-use separation |
| Electricity bill | CAD $140 and its billing dates | The original cost and period under review |
Which documents should go to my accountant?
Save the original bills with the allocation worksheet. Give each line in the worksheet a bill reference, the dates it covers, the full billed amount and the portion proposed for review. Mark a missing bill or an uncertain classification explicitly. Keep equipment purchases and room renovations in a separate review list so a gear receipt does not become part of a household utility calculation.
In Clef's expense editor, the optional Receipt / Reference # and Internal Notes fields can help a reviewer find the underlying evidence. For an expense you already record in Clef, use the reference to identify the bill and the note to point to the allocation worksheet and period. Keep the full working calculation with the supporting records. Ask your accountant how to handle household bills paid personally before entering them into the business books.
The CRA limits business-use-of-home expenses so they cannot create or increase a loss from that business. If the limit applies, ask your accountant what can carry forward and keep the earlier calculation with the current records.
What else should I know?
Does an evening of personal practice count as business use?
Classify a session by what it was for. Keep clearly personal sessions out of the business-hours log and identify uncertain sessions for review instead of treating every hour spent making music as paid work.
What if I moved the setup to another room midyear?
Keep both sets of measurements and the date of the move. Split the working record into periods so your reviewer can match bills and usage to the right layout.
Should I apply the room percentage to home internet?
The CRA folio treats internet separately from workspace expenses. Where service is shared, retain evidence for a reasonable business-use allocation specific to that service.
Does soundproofing go in the same calculation as electricity?
Keep the invoice and a description of the work in a separate review list. Ask your accountant to assess whether the work is a repair or a capital improvement before including it in any claim.
