Is it true that since I started my business in July 2021, I don’t have to start filing quarterly taxes until next year (2022)?
Not exactly. You could be subject to a penalty for underpayment of estimated tax.
You can avoid that penalty if you either owe less than $1,000 in tax after subtracting your withholding and refundable credits, or if you pay withholding and estimated tax of at least 90% of the tax for the current year or 100% of the tax shown on your return for the prior year, whichever is smaller.
