Who needs to make estimated quarterly tax payments?
According to the IRS, “in most cases, you must make estimated tax payments if you expect to owe at least $1,000 in tax for 2009 (after subtracting your withholding and credits) and you expect your withholding and credits to be less than the smaller of: 90% of the tax to be shown on your current year’s tax return, or 100% of the tax shown on your prior year’s tax return. (Your prior year tax return must cover all 12 months.)” So basically, if you have any income over $1,000 that has not had federal taxes withheld then you will need to make quarterly payments. This applies to any source of revenue, from self-employment earnings to interest and dividend payments.
