The home office deduction for freelancers, without the myths

The home office deduction has a reputation for being an audit magnet. In most countries it is a routine, expected claim for self employed people who genuinely work from home, and the freelancers who skip it out of vague fear are handing over money for nothing.

This is general guidance. The rules differ significantly by country, so check the specifics with a local accountant.

The usual qualifying test

Most systems ask two things:

• Regular use. You work there consistently, not occasionally.
• Business use. The space is used for your business rather than for personal life. Some jurisdictions demand exclusive use of a defined space, others allow a proportional claim on a shared room.

The strictest interpretation, exclusive use, means the space cannot double as the family dining room. The more common practical interpretation allows you to claim a proportion of a room used partly for work. Know which applies where you live before you calculate anything.

The two calculation methods

• Simplified or flat rate. A fixed amount per square metre, or a flat monthly amount based on hours worked from home. Minimal record keeping and usually a smaller deduction. Good for anyone with a modest space or low tolerance for admin.
• Proportional or actual cost. Work out the percentage of your home used for business, usually by floor area, then claim that percentage of eligible household costs.

The proportional method typically produces a larger deduction and requires you to keep the underlying bills.

What usually goes into a proportional claim

• Rent, or mortgage interest rather than capital repayment
• Electricity, gas, and water
• Home insurance
• Internet and phone, apportioned by business use
• Council or property tax where allowed
• Repairs and maintenance affecting the whole property

Costs relating exclusively to the workspace, such as painting only that room, are often claimable in full rather than proportionally. Costs relating to a purely personal part of the house are not claimable at all.

The records to keep

Documentation, not aggression, is what makes a claim safe:

• A note of the floor area of the workspace and of the whole property, with the percentage you derived.
• The bills backing every cost you apportioned. Not a summary, the actual documents.
• A photo of the workspace, taken once. Trivial to produce now, impossible to reconstruct in three years.
• Consistency year to year. A percentage that jumps around without an explanation invites questions that a stable one never gets.

Capturing utility bills the month they arrive, rather than hunting for twelve of them in April, is the difference between a five minute claim and a lost weekend. Scanning them into a receipts tool as they land solves this permanently.

Things that catch people out

• Selling the property. In some jurisdictions, claiming a portion of a home as business use affects the capital gains treatment when you sell. Ask before you claim if you own your home.
• Working from a shared or rented desk elsewhere. Coworking fees are usually a straightforward business expense and can sit alongside a smaller home claim, but double claiming the same hours is not allowed.
• Employees versus self employed. Many countries removed or restricted the deduction for employees while leaving it intact for the self employed. Advice written for employees does not apply to you.
• Claiming an implausible proportion. Half of a two bedroom flat as office space will be questioned. A tenth of it will not.

TL;DR

• Regular and business use are the usual tests. Some countries require exclusive use of a defined space.
• Flat rate is simpler, proportional is usually larger. Pick one and stay consistent.
• Keep the floor area calculation, the underlying bills, and one photo of the space.
• Ask about the property sale implications before claiming if you own your home, and confirm the rules locally.
