Practical guidance for living healthier, aging well, and becoming more of who you want to be.
A plain-English introduction to records, net profit, self-employment tax, and estimated payments in the United States.
Income from a side job is still income. A platform’s reporting form does not determine whether earnings are taxable, and part-time or temporary work is not automatically exempt.
Income, expenses, and net profit
Keep records of payments received and ordinary business expenses. Net profit is generally business income minus allowable business expenses. Personal spending should remain separate.
The $400 rule
The IRS states that a federal return is generally required when net earnings from self-employment are $400 or more. Other filing requirements may still apply below that amount.
Self-employment and estimated tax
Independent contractors generally do not have an employer withholding Social Security, Medicare, and income taxes. Estimated tax may be required during the year. IRS Form 1040-ES helps determine whether and how much to pay.
A simple recordkeeping system
- Use a separate account or card when practical.
- Record every payment, including cash and platform income.
- Save receipts and note the business purpose.
- Track mileage only under applicable IRS rules.
- Review profit and a possible tax reserve monthly.
Do not guess about worker status
Being called a contractor does not automatically make it correct. Federal and state rules can differ and are changing. Seek qualified guidance if a business controls how, when, and where you work but treats you as self-employed.
Bottom line: Start records with the first dollar, not at tax time. Clean records make it easier to understand whether a side hustle is truly profitable.
