Made about 1000-1300 cutting grass for neighbors do i have to claim on my taxes and how ?

The website has an article about determining "What is Earned Income".  https://turbotax.intuit.com/tax-tools/tax-tips/Taxes-101/What-Is-Taxable-Income-/INF15613.html

To decide how to report the income, please visit this FAQ:  https://ttlc.intuit.com/replies/3300312

Yes, you are required to report the income. And you will owe some self employment tax.  Assuming your parents can claim you as a dependent, be sure you indicate that someone else can claim you when you prepare your return.

Thanks a lot

You are welcome.  Be sure that you deduct expenses such as gas for the mower when determining how much of your income is taxable.

Oh I'm grown with a full time job and children

Oh, I misunderstood.  Sorry.  So yes, you do need to report it is business income.

And she paid for the gas it was just one lady

Even though I don't have my own business

Well, from an IRS perspective you have a lawn mowing business in addition to your full time job.  This will generate a Schedule C or C-EZ and a Schedule SE.

OK thank you very much

My dad is a landscaper and makes cash. Can he file taxes. He never received any of his stimulus checks 

Yes, he should file his landscaper income as self employment. A document is not required and all income received for services must be included on his tax return.

 

He should have a record of his receipts, customers, etc., to show his business activity.  A separate bank account is very helpful and recommended to show both income and expenses related to the business.

 

Schedule C is supported in TurboTax Self-Employed (both online and in the mobile app) and in all personal 1040 versions of the TurboTax CD/Download software.

 

To set up your business:

1. Open or continue your return.
2. Search for schedule c and click the Jump to link in the search results.
3. Answer Yes to Did you have any self-employment income or expenses?
   • If you've already entered self-employment work and need to enter more, select Add another line of work.
4. Follow the onscreen instructions.
