What it means
A SOHO business is typically owner-led, with very few employees and low overheads. The owner may use a spare room, a shared workspace or a small rented unit, and equipment is usually modest.
Because it is so small, the business often relies on cloud software, a laptop and a mobile phone instead of dedicated infrastructure. For finance purposes the main issue is separating business and personal costs.
Where tax rules allow, a share of home costs such as heating, electricity, internet and rent or mortgage interest can be claimed against business income. The rules differ widely between countries, and many require that the space is used regularly and mainly for work, so records matter.
Banks, software firms and insurers use SOHO as a customer segment. Packages are designed with simple accounts, easy invoicing and affordable cover, because these customers lack a finance department.
Technology suppliers also sell routers, printers and accounting tools tailored to this group. SOHO owners face particular risks.
Their income can be irregular, personal and business assets are often entangled, and a single illness or lost client can affect the whole business. Good habits such as a separate business bank account, a tax reserve and regular invoicing help reduce those risks.
The popularity of remote working has made the term feel broader. Many employees now work from home, but they are not SOHO businesses because they do not run their own enterprise.
The distinction matters for tax, because a home office deduction usually belongs to the self-employed or to employees only in limited circumstances. Insurance is another area that is easy to overlook.
A standard home policy may not cover business equipment or client visits, so a SOHO owner should ask the insurer whether extra cover is needed.
In practice
Real-world examples.
Example
A freelance graphic designer works from the spare bedroom of his flat. He tracks the share of floor space used for work and keeps utility bills for his accountant. At year end he claims a proportion of those costs against his business income.
Example
A bank launches a business account for the SOHO market, with no monthly fee, mobile invoicing and a small overdraft. Its product team knows these customers will not visit a branch. Sign-ups come mainly through the bank's app.
Example
A technology reseller bundles a router, backup storage and accounting software into a single monthly subscription for home-based businesses. The price is $39 a month, which suits owners who want predictable costs. Finance tracks the subscription revenue as a recurring income stream.
Formula
Calculation
Business share of home costs = (Office area / Total home area) x Annual home costs
Suppose a consultant uses a 150 square foot room in a 1,500 square foot home, and her annual home costs for heating, power and internet total $24,000. The office share = 150 / 1,500 = 0.10, or 10%. The claimable amount = 0.10 x 24,000 = $2,400, assuming her local tax rules permit this method. Her accountant checks the rules each year because they change.Case study
Seen in the real world.
Maple and Reed Consulting is an illustrative, fictional two-person marketing consultancy run from the founder's home. For its first two years she paid business costs from her personal account and could never tell what the firm had really earned.
At the advice of an accountant, she opened a separate business account, set aside 25% of each invoice for tax and began recording the proportion of her home costs used for work. At year end the numbers showed a profit of $48,000 rather than the $60,000 she had assumed, because she had not counted her software, insurance and travel costs.
The illustrative lesson is that a small business still needs proper records. Separating the accounts gave her a truthful picture and made it easier to obtain a business loan later. She also found that the monthly review of her figures took less than an hour once the habit was established.
Watch out
Common mistakes.
- Claiming a home office deduction without keeping records of floor area, bills and how the room is used.
- Paying business costs from a personal account, which blurs profit and complicates tax returns.
- Assuming that working from home makes someone a SOHO business, when the term refers to running one's own enterprise.
Questions
People also ask.
Can an employee claim home office costs?
It depends on the country, and many tax systems allow it only in limited circumstances, so check local rules.
Why do banks treat SOHO customers differently?
They have small, irregular incomes and no finance team, so providers design simpler and cheaper products for them.
What records should a SOHO owner keep?
Invoices, receipts, bank statements, utility bills and a log of how the workspace is used.
