Quick answer: Storefront revenue is taxable self-employment income in most places: file the platform tax interviews (W-8/W-9) to avoid excess withholding, set aside a fixed slice of every payout, track expenses from day one, and learn whether your country expects quarterly prepayments. One hour with a local accountant beats every forum thread.
Storefront revenue is taxable self-employment income in most places: file the platform tax interviews (W-8/W-9) to avoid excess withholding, set aside a fixed slice of every payout, track expenses from day one, and learn whether your country expects quarterly prepayments. One hour with a local accountant beats every forum thread. That's the short version — the sections below get into the how, the why, and the mistakes worth dodging.
The storefront paperwork that controls withholding
Steam, consoles, and app stores make you complete tax interviews before paying out; answer them properly and (where applicable) supply your country's treaty details, or US-sourced revenue can lose a heavy default withholding slice. Non-US devs: the treaty rate fields are the ones that matter — many devs overpay for years from a mis-clicked form.
Payouts also arrive after the platform's cut, refunds, and chargebacks, on a delay. Your taxable revenue and your bank deposits will never quite match; keep the platform reports, since they're the source of truth.
Set aside money like it isn't yours
Self-employment income arrives untaxed, and the bill lands later — often with prepayment schedules (US quarterly estimates and equivalents elsewhere) that surprise first-timers with penalties. The defensive habit: a fixed percentage of every payout (30% is a common starting point, tune locally) moved to a separate account on arrival.
The first profitable year is the dangerous one: a launch spike's taxes come due months after the money stopped feeling new.
Expenses are real money; track them like it
Engine licenses, asset packs, contractor invoices, hardware, software subscriptions, a home-office share, conference travel — legitimately deductible in most regimes, but only if documented. A spreadsheet or cheap accounting tool updated monthly turns tax season from archaeology into a report.
Edge cases worth professional advice: VAT/GST registration thresholds (storefronts handle consumer VAT, but B2B and direct sales differ), crowdfunding proceeds (often taxable on receipt), and whether your jurisdiction lets pre-revenue dev costs carry forward.
Protect the downside first
Indie game revenue is lumpy and unpredictable, and most advice quietly assumes a hit. Plan for the median outcome instead: a launch that earns modestly and grows slowly. Keep fixed costs low, keep some runway, and make deals you could live with if the game sells a tenth of your hopes.
None of this is pessimism — it's what lets you take real creative risks. A developer who can afford to miss is a developer who can afford to be interesting.
Get unglamorous things in writing
Splits, deadlines, deliverables, who owns what if the project dies — the awkward conversations are dramatically cheaper before money shows up. A one-page agreement between friends feels like overkill right up until it's the only thing that saves the friendship.
You rarely need a lawyer for a first project, but you do need clarity. Write down what was agreed, date it, and make sure everyone has a copy. Future-you will be grateful.
The quiet work that protects all of this
Everything in this post gets undone by an unstable build. A great store page, a clever marketing beat, a perfect jam entry — none of it survives 'crashed twice, refunded'. Stability isn't a feature players praise, but it's the floor everything else stands on.
Give yourself visibility before you need it: crash reports with stack traces, a simple way for players to flag issues from inside the game, and a habit of fixing the top recurring error before adding anything new.
Putting it to work
Don't try to act on all of this at once. Pick the one change that costs you the least and pays the most this week, do it, and see what actually happens before reaching for the next.
Most of this rewards steadiness over intensity. A small improvement made every week, checked against how real players respond, outruns any single burst of effort — in this corner of game development and every other one.
Make the guesses cheap, the agreements written, and the runway longer than the plan.
