Most businesses will deposit their income tax withholdings, Social Security, and Medicare taxes on a quarterly, monthly, or semi-weekly basis.
If you're not sure when your taxes are due, you can usually determine your deposit schedule by looking at your total taxes after adjustments, (line 12 on Form 941) for the lookback period, which runs from July 1 to June 30.
