Domain Investing and Taxes: What US Investors Should Know
Hobby versus business, what's deductible, how sales are treated, and the records to keep — plus the questions worth taking to an actual accountant.

Domain sales are income. That's the short version, and it surprises a number of people whose first sale arrives as an unexpected email.
Getting the framework right early is much easier than reconstructing it later.
Hobby or business?
This is the first fork and it changes everything downstream.
The IRS distinguishes activities carried on for profit (a business) from those that aren't (a hobby). It's not a box you tick — it's a judgment based on facts. Relevant factors include:
- Do you operate in a businesslike manner, with books and records?
- Do you put real time and effort in?
- Do you depend on the income?
- Have you made a profit in some years?
- Do you have relevant expertise?
- Are you changing methods to improve profitability?
The consequence is significant. Under current rules, hobby expenses are generally not deductible, while hobby income is still taxable. A business, by contrast, can deduct ordinary and necessary expenses against its income.
For a domain investor, that's the difference between deducting several thousand dollars of annual renewals and deducting none of it.
Keeping proper records — the tracking spreadsheet from the previous chapter — is both good practice and part of what demonstrates businesslike operation.
What's potentially deductible
If you're operating as a business, expenses that plausibly relate:
- Domain registration and renewal fees — usually the largest line
- Marketplace commissions on sales
- Escrow fees
- Broker commissions
- Tools and subscriptions used for research
- Business formation and legal costs
- A home office, if it genuinely qualifies
- Education related to the business
- Professional fees — your accountant's bill
How and when each is deducted varies. Some may be current expenses; others may need to be capitalized into the cost of the asset. This is exactly the sort of thing to ask a CPA rather than guess at.
How sales are treated
Here the answer genuinely depends on your situation, and it matters a lot.
Broadly, the question is whether domains are inventory held for sale in the ordinary course of business, or capital assets held for investment.
- If they're inventory, proceeds are generally ordinary income, taxed at your marginal rate, and self-employment tax may apply.
- If they're capital assets held more than a year, long-term capital gains treatment may apply, typically at a lower rate.
The distinction turns on facts: how frequently you buy and sell, whether you're actively marketing, how long you hold, and how you present the activity. Someone doing hundreds of transactions a year looks like a dealer. Someone who sold three names from a long-held portfolio looks different.
This is the single highest-value question to put to an accountant, because the difference in rate is substantial.
Cost basis
Whatever the treatment, you need to know what each domain cost you — its basis — to compute gain.
That includes the acquisition price plus, potentially, certain associated costs. Renewals paid while holding may be handled as current expenses or as additions to basis depending on the treatment; another CPA question.
This is why per-domain acquisition records matter. Reconstructing what you paid for a name you bought four years ago, at auction, with fees, is unpleasant and imprecise. Log it when you buy it.
Records to keep
Keep, per domain:
- Acquisition date, price, and where from
- All renewal payments
- Sale date, gross price, commission, and net proceeds
- Escrow or marketplace statements
- Any broker agreements
And overall: your annual portfolio export, bank and payment records, and receipts for tools and services.
Marketplaces and payment processors may issue tax forms depending on volume and thresholds, but the reporting obligation is yours regardless of whether a form arrives. Don't assume no form means no income to report.
Structure
Many investors operate as a sole proprietorship initially, which is simple, and some form an LLC as things grow. An LLC is primarily about liability separation rather than tax treatment by default, though it opens options.
Whether that's worth it depends on scale, your state, and your circumstances. It's a conversation with an accountant, not a decision to make from an article.
Practical suggestions
Set money aside when a sale lands. A meaningful share of that $2,434.50 isn't yours. Putting a portion aside immediately avoids an unpleasant surprise later.
Separate your money. A dedicated account or card for domain activity makes bookkeeping vastly easier and supports the businesslike-operation case.
Talk to a CPA once you have real sales. Before your first sale it's mostly theoretical. After a few thousand dollars of proceeds, an hour with a professional will likely pay for itself several times over.
Don't optimize prematurely. Elaborate structures for a portfolio producing three sales a year is effort spent in the wrong place. Get the records right first.
Non-US readers
Everything above is US-specific. The underlying questions travel — is this a business or a hobby, are domains inventory or capital assets, what's deductible — but the answers differ by country, and VAT or GST may apply to sales in ways that have no US equivalent. Find a local professional.
The one thing to take away
Keep records from the first domain you buy, even when it seems unnecessary. The tax treatment questions all depend on facts you can only document contemporaneously, and the cost of reconstructing years of acquisitions is far higher than the cost of logging them as you go.
