Revenue Comes With Responsibilities
The moment your app earns money, you have tax and bookkeeping obligations. Getting this wrong leads to penalties; getting it right keeps more money in your pocket.
This lesson covers the financial basics every indie founder needs.
Gross vs Net Revenue
What the store reports and what hits your bank differ. Apple and Google take a commission (often 15-30 percent) before paying you.
function netAfterStoreFee(gross, feePercent) {
return gross - (gross * feePercent / 100);
}
console.log(netAfterStoreFee(1000, 30));Stores Often Handle Sales Tax
For most consumer apps, the stores act as merchant of record, collecting and remitting sales tax or VAT for you.
This is a big relief — but you still owe income tax on your earnings.
Income Tax on Profits
You are taxed on profit, not revenue. Profit is income minus deductible business expenses. Track expenses carefully — they lower your tax bill.
function profit(revenue, expenses) {
return revenue - expenses;
}
console.log(profit(50000, 12000));Deductible Expenses
Common deductions for app businesses:
- Developer account fees
- Hosting and BaaS costs
- Software subscriptions
- Marketing spend
- A portion of home office and devices
Keep receipts for everything.
Withholding on Foreign Payouts
If you sell into the US from abroad, you may need to file a tax treaty form (like a W-8BEN) to avoid heavy withholding on royalties.
Filing the right form can cut withholding from 30 percent to as low as zero.
Separate Business Finances
Open a dedicated business bank account. Mixing personal and business money makes bookkeeping a nightmare and weakens any liability protection from your business entity.
Bookkeeping Basics
Bookkeeping means recording every transaction. At minimum, log:
- Date
- Amount
- Category (income or expense type)
Tools like spreadsheets or accounting software keep this organized.
Setting Aside for Taxes
Do not spend money you owe the tax office. A safe habit: set aside a fixed percentage of every payout into a separate tax savings account.
function setAside(payout, taxRate) {
return payout * taxRate / 100;
}
console.log(setAside(3000, 25));When to Get a Professional
DIY works early, but as revenue grows, an accountant pays for themselves through deductions, compliance, and time saved.
Cross-border app income especially benefits from expert advice.
A Financial Hygiene Checklist
Stay clean:
- Separate business bank account
- Track all income and expenses
- File treaty forms to avoid over-withholding
- Set aside taxes from every payout
- Get an accountant as you scale
Good financial hygiene protects and grows your business.
Quick Check
Test your app finance knowledge.
Recap
You learned to manage app revenue:
- Stores take a commission and often handle sales tax/VAT
- Income tax is on profit, so track deductible expenses
- File treaty forms to avoid over-withholding on foreign payouts
- Separate business finances and keep clean books
- Set aside taxes and hire an accountant as you scale
Sound finances keep your indie business healthy and legal.
