If you’re self-employed, the business share of your Starlink bill is generally deductible as a business expense. Most W-2 employees can’t deduct it on a federal return.
This is general information drawn from IRS publications, not tax advice. A tax professional can apply it to your own return, and the rules can change from one tax year to the next.
Who can deduct
Self-employed people. If you report business income on Schedule C, the IRS’s instructions for that form cover the business expenses you can deduct, which must be ordinary and necessary for the business. Internet service you use to run the business can qualify for the share you use for business. A home bookkeeping practice, a contractor who quotes and invoices from the kitchen table in the Upper Peninsula, a freelance designer in the Texas Hill Country: the test is the same.
Employees. IRS Publication 587 explains that employees generally can’t deduct the cost of business use of their home on a federal return, and most unreimbursed work expenses aren’t deductible for employees either. If your employer asks you to work from home, ask whether it reimburses internet costs instead. Check the edition of Publication 587 for the year you’re filing.
Both at once. If you have a W-2 job and a side business, only the side business’s share of the bill counts, and it goes with that business’s Schedule C.
Where the home-office rules fit
Publication 587 is about deducting part of your home itself. To take that deduction, it requires using part of the home regularly and exclusively for the business, among other tests.
A Starlink plan isn’t a room of your house, and the IRS publications cited here don’t name satellite internet. Whether deducting a share of your internet bill depends on meeting the home-office test is a question to settle with a tax professional before you file. Either way, the same principle runs through both: when something serves both your business and your personal life, only the business share counts.
Working out the business share
The IRS doesn’t publish a Starlink formula, so the method is yours to choose and defend. Pick one you can explain and document. Two common approaches:
- By time. Log the hours the connection is used for the business in a typical month, against the hours it’s used in total.
- By use. If one device or one person’s use is all business, estimate that share of the household’s total use.
Whatever you choose, write down the method and keep the log. A share you guessed at is hard to support if anyone asks.
Here is a worked example at a 40% business share, using the Nov 4, 2026 prices starlink.com listed for the US with no address entered (our math):
| Plan, Starlink US national list, Nov 4, 2026 | Per month | 12 months | Business share at 40% |
|---|---|---|---|
| Residential 100 Mbps (select areas) | $49.50 | $594 | $237.60 |
| Residential 200 Mbps (select areas) | $76.50 | $918 | $367.20 |
| Residential Max | $143 | $1,716 | $686.40 |
| Roam 100GB | $55 | $660 | $264 |
Your own invoices are the numbers to use, not this table. Starlink prices Residential plans by address, and the level you pay can differ from the national list.
A deduction lowers your taxable income. It doesn’t cut your tax bill by the same amount: a $237.60 deduction saves the tax you would have paid on $237.60 of income, which depends on your rates.
The kit
Whether you own the kit decides what there is to deduct.
A kit you buy. On Nov 4, 2026, starlink.com charged $349 for a Standard or V5 kit and $149 for the Mini. A kit is equipment that lasts more than a year, which IRS rules treat differently from a monthly bill. Its cost is normally spread over several years, though IRS rules also let many small businesses deduct lower-cost items in the year they buy them, through an election known as the de minimis safe harbor. The business-use share applies to the kit as well. Which route fits your situation, and the paperwork it needs, is a question for a tax professional.
A kit you rent. Starlink keeps ownership of a rented kit, so there’s no equipment of yours to spread over years. How to treat the one-time activation, and any monthly rental fee that checkout lists, is another question for a tax professional. Rent or buy lists the dated kit routes and compares them on cost alone, before any tax effect.
Putting it together: one example
Suppose a self-employed bookkeeper works from home on Residential 200 Mbps, at an address priced at $76.50 a month (the Nov 4, 2026 national-list level). The household shares the connection.
- Measure. In a sample month, the business uses the connection about 120 of the 300 hours it’s in use, a 40% share.
- Apply it to the bills. Twelve invoices at $76.50 come to $918. The business share is $367.20 (our math).
- Apply it to the kit. Had the bookkeeper bought a $349 kit, the business share of its cost would be $139.60 (our math), deducted over several years or in year one, depending on the route chosen with a tax professional.
- Write it down. The sample-month log, the 40% method and the invoices go into the year’s tax file.
The figures are an illustration, not a benchmark. A different household, plan or method gives a different share.
Mistakes that are easy to make
- Deducting the whole bill. If the family streams on the same connection, only the business share counts.
- Using a list price. Starlink prices Residential plans by address and prices move, so the amounts on your own invoices are what you paid.
- No written method. A percentage without a log or a note behind it is hard to support later.
- Mixing jobs. A W-2 job’s use of the connection doesn’t add to a side business’s share.
Questions to bring to a tax professional
A short list saves time at the appointment:
- Which Schedule C line should internet service go on?
- Does the home-office test in Publication 587 matter for the internet share, or only for the home itself?
- Should a bought kit be spread over several years or deducted in the year of purchase, and which election does that take?
- How should a rental activation, or a monthly rental fee, be treated?
- Do your state’s rules differ from the federal ones?
Re-measure the business share when things change: a new plan, a new person in the house or a busier season can move it. A sample month each year keeps the number current.
Records to keep
A short list goes a long way:
- Every Starlink invoice for the year, from your Starlink account.
- The kit receipt, if you bought the kit, with the purchase date.
- Your method note: how you worked out the business share, and the log or sample month behind it.
- A copy of the year’s total, so the numbers on your return can be traced back to the invoices.
Keep them with the rest of your tax records for that year. Your tax professional can tell you how long to hold on to them.
