No matter what type of small business entity you have, you have to pay quarterly estimated taxes if the business owes income taxes of $1,000 or more. Corporations only have to pay quarterly estimated taxes if they expect to owe $500 or more in tax for the year.
Before you owned a business, filing taxes was a one-time thing. But as a small business owner, you’ll have to pay the IRS four times per year. On one hand, that’s four more tax deadlines you might miss. But on the bright side, by the time your yearly tax deadline comes around, you’ll have already paid three-quarters of your tax return.
To make things even more complicated, businesses must deposit federal income tax withheld from employees, federal unemployment taxes, and both the employer and employee social security and Medicare taxes. Depositing can be on a semi-weekly or monthly schedule.
