CrowdGen by Appen requirements

1. Set aside money for taxes

   Nobody withholds taxes from contract pay. If your net earnings from self-employment are $400 or more in a year, you owe self-employment tax of 15.3% (Social Security and Medicare) on top of regular income tax. You have to report all of it, even if the platform never sends you a 1099. Move a share of every payout into a separate account so the bill doesn't surprise you.

2. Know the quarterly tax dates

   Independent contractors may need to pay estimated taxes four times a year to avoid a penalty: April 15, June 15, September 15, and January 15. If a date lands on a weekend or holiday, it moves to the next business day. If you also have a regular W-2 job, you can have extra tax withheld from that paycheck instead, using a new Form W-4.

3. Keep receipts and payout records

   Save receipts for work expenses (phone, gear, supplies, fees) and keep a record of every payout. Deductible expenses lower the tax you owe, but only if you can show them. A free spreadsheet works; so does a separate debit card used only for work costs.

4. Have a bank account or debit card ready

   Platforms pay by direct deposit or to a debit card, and faster cash-out options usually need a debit card. Check the app's payout terms before your first cash-out, since instant transfers can carry a fee.
