Based on your question, it sounds like your husband won't be an employee, and won't receive a Form W-2 for his income.

If this is the case, you can pay your taxes when you file your income tax return, but it's a really bad idea.  You'll most likely have to pay additional penalties that you wouldn't face if you paid throughout the year.

Please see the TurboTax Help article “Do I need to make estimated tax payments to the IRS?” for additional information.
