Running a business from home without breaking a rule

If you’re starting a business with no capital, the business is almost certainly going to live where you do. The kitchen table, a spare room, the garage, a corner of a rented flat. That’s not a compromise, it’s how most very small businesses begin, and the tax code, your city and your landlord all have something to say about it.

Here’s the thing most people get wrong, and the reason this article exists: the rules come in separate layers, and no layer checks the others for you. The IRS will happily let you deduct a home office in a building your lease forbids you to work from. Your city can approve you for a permit while your homeowner’s policy quietly leaves your business equipment uncovered. Registering the business and getting an EIN does not make the zoning question go away. You have to clear each layer on its own, and clearing one tells you nothing about the rest.

There are five layers worth checking: local zoning, business licences, your lease or mortgage situation, the IRS home office rules, and insurance. Most take an afternoon. One, the tax layer, is worth real money every year, so we’ll spend the most time there.

Layer one: zoning, the rule people forget exists

Every address sits inside a local zoning map, and neighbourhoods are generally zoned either commercial or residential. The Small Business Administration is blunt about it: zoning ordinances “can restrict or entirely ban specific kinds of businesses” in an area. You may face fewer restrictions working from home than you would opening a shopfront, but zoning ordinances still apply to home-based businesses. The SBA’s guidance is that anyone who buys, rents, builds, or works out of a physical property should confirm it conforms to local zoning before committing.

Zoning is controlled at the local level, which means there is no national answer to “can I run my business from my house.” Conditions vary city by city, and sometimes neighbourhood by neighbourhood. The only reliable move is the unglamorous one: contact your city or county planning department, describe what you actually do (clients visiting or not, deliveries or not, anything stored on site), and ask what applies. Many places have a home-occupation permit process; what it requires is written in your municipal code, not in any general guide.

The mechanism to understand is that zoning exists to protect neighbours from the effects of a business, not to punish you for working. A freelance bookkeeper who never has a visitor looks very different to a zoning office than a car repair operation in the driveway, even if both are “home businesses” on paper.

Layer two: licences don’t shrink because you’re small

Licensing is about the activity, not the size of the operation. The SBA notes that most small businesses need some combination of licences and permits from federal and state agencies, that states “tend to regulate a broader range of activities than the federal government,” and that your county or city may require licences on top of that.

A handful of activities trigger federal licensing no matter how small you are. The SBA’s licence guidance lists them: agriculture, alcoholic beverages, aviation, firearms and ammunition, fish and wildlife, commercial fisheries, maritime transport, mining and drilling on federal lands, nuclear energy, and broadcasting. If you’re nowhere near that list, your licensing questions are state and local ones, and food is the big trap there: selling food made in a home kitchen is governed by state health rules that vary widely, so check your state’s regime specifically before selling a single jar of anything.

If you haven’t registered the business at all yet, start with structure, EIN and licences in order, and know that free, in-person help exists if the paperwork is stalling you.

Layer three: your lease is a contract, and it applies

If you rent, your lease is a private contract and it may say things about how the property can be used. Nothing you do with the IRS or your city overrides it. Read it before you commit to anything, and if it’s silent or unclear, ask the landlord in writing.

There’s a common assumption that renters are shut out of home-business life. They aren’t. The IRS explicitly confirms that renters can take the home office deduction, and rent itself is a deductible expense under the regular method. The tax code does not care whether you own or rent. Your lease might.

If a dispute with a landlord develops, USA.gov points tenants to state-level help: your state attorney general, housing agency, or state tenant-rights handbook. If HUD insures or manages the property, there’s a HUD Multifamily Housing Complaint Line as well.

Layer four: the home office deduction, and the test that decides everything

This is the layer that puts money back in your pocket, and it hinges on one test almost everyone misreads. To deduct a home office as a self-employed person, the space must generally be used exclusively and regularly for the business. Exclusive means exclusive. IRS Publication 587 gives the example of an attorney whose den doubles as a family recreation room: no deduction, full stop. The space can be a room or just a separately identifiable area, and it “does not need to be marked off by a permanent partition,” but if the kids do homework there in the evening, it fails.

There are exactly two exceptions to exclusive use. Space used regularly to store inventory or product samples qualifies without being exclusive, provided you sell at wholesale or retail and your home is the only fixed location of the business. And a daycare operation qualifies on a prorated basis, provided you’ve applied for, been granted, or are exempt from a state licence. Everything else must pass the exclusive-use test.

Two more points people routinely get wrong. First, working at other locations doesn’t automatically disqualify you: your home can qualify if you use it exclusively and regularly for administrative or management work and there’s no other fixed location where you do substantial amounts of that work. Occasional phone calls and meetings at home don’t count, though. Second, employees cannot claim this deduction at all. It belongs to the self-employed. A remote employee with a dedicated office gets nothing; a self-employed person with the same room does.

Simplified or regular: pick a method each year

Once you qualify, you choose how to calculate the deduction, and you make the choice year by year on your timely filed, original return. Once you’ve used a method for a given year, you can’t switch methods for that same year.

The simplified option exists because the paperwork was drowning people; the IRS estimated it would save small businesses 1.6 million hours of recordkeeping a year. For a renter with a small dedicated space, it’s often the sane choice. Note that it only simplifies the maths, not the eligibility: exclusive and regular use is still required.

For homeowners there is a trap inside the regular method worth knowing about. Depreciation you were allowed to claim counts against you when you sell the home, even if you never actually claimed it. You can’t dodge recapture by skipping the deduction. The simplified method genuinely avoids this, because depreciation under it is treated as zero and your home’s basis isn’t reduced.

Either way, the deduction can’t create a business loss: it’s capped by the gross income from the business use of your home. Under the regular method, disallowed amounts carry forward; under the simplified method, they’re gone. If your income is thin or irregular, which for this readership it often is, that distinction matters. And if you’re claiming benefits alongside the business, read up on how self-employment income interacts with SNAP, SSI and Medicaid before your first tax return, not after.

Layer five: insurance, the quiet gap

A homeowner’s or renter’s policy is built around losses like fire and burglary, not around a business operating inside the walls. The SBA’s business insurance guidance describes home-based business insurance as something added to a homeowner’s policy as a rider, covering a small amount of business equipment plus liability if a third party is injured, which tells you what the base policy isn’t designed to do. For anything beyond a laptop and a printer, the SBA points home-based owners especially towards a business owner’s policy, which bundles property and liability cover.

Two related points from the same guidance. Forming an LLC or corporation gives only limited protection for your personal assets, so insurance isn’t made redundant by your business structure. And the moment you take on staff, the federal government requires businesses with employees to carry workers’ compensation, unemployment and disability insurance; if that step is anywhere on your horizon, here’s what hiring your first employee actually obliges you to do.

Clearing all five layers

None of this is designed to stop you. Zoning protects your neighbours, licensing protects your customers, your lease protects the landlord’s property, the exclusive-use test protects the tax base, and insurance protects you. Each layer has a cheap or free way to check it: a call to the planning department, the SBA’s licence pages, a careful read of your lease, a tape measure and Publication 587, and a conversation with your insurer before anything goes wrong rather than after.

Frequently asked questions

Can I claim the home office deduction if I rent? Yes. The IRS confirms renters qualify on the same tests as owners, and under the regular method a share of your rent is a deductible expense. The exclusive-and-regular-use test applies the same way. What your lease permits is a separate question the IRS doesn’t ask.

My desk is in the corner of the living room. Does that qualify? It can, but only if that corner is used solely for the business. The space doesn’t need a wall or partition, just a separately identifiable area, and genuinely exclusive use. If the same spot serves personal purposes too, it fails, exactly like the attorney’s den in the IRS’s own example.

I’m a remote employee with a dedicated home office. Can I deduct it? No. The IRS states employees are not eligible for the home office deduction, even using the simplified method. The deduction is for self-employed people filing Schedule C, plus specific cases like licensed home daycare.

Is the simplified method always the better choice? Not always. It caps out at $1,500 ($5 per square foot, 300 square feet maximum) and any amount above your business income is lost rather than carried forward. The regular method can produce a larger deduction and carries excess forward, but demands full records and, for homeowners, triggers depreciation recapture at sale. You can choose fresh each year on your timely filed original return.

Do I really need separate insurance for a laptop and some stock? Check before assuming. The SBA describes home-based business cover as a rider added to a homeowner’s policy for a small amount of equipment plus liability, which means the base policy alone isn’t built for business losses. Ask your insurer what your current policy would actually pay if business property were damaged or a client were injured at your home.
