Check with your accountant or refer to past tax returns to determine if you can pay annually or need to pay quarterly. There’s no disadvantage to paying quarterly. You can, on the other hand, be assessed fees if you decide to pay annually but earn too much (and should have paid quarterly).
The 1040ES is a form that will help you estimate your quarterly taxes. It’s available here –

Once you know how much you need to pay every three months, it’s time to create a plan to save for it. This isn’t your emergency savings plan. This is a different savings plan designed to take the financial pain and stress out of paying your taxes.
Unlike an emergency savings plan, your tax savings doesn’t need to be stored in a separate account. If you keep good records you can simply keep your tax savings in your standard business checking account. If you believe you might be tempted to spend the money, then open up another savings account specifically for your quarterly taxes.
Step Two: Weekly or Monthly?
The easiest way to build your savings is to establish automatic deductions. For example, you may have $500 deducted from your business checking account each month and added to your tax savings account. To determine how much to deduct, simply divide your anticipated quarterly tax payment by three months or 12 weeks.
If you are keeping all of your money in one account, you’ll want to make sure you build up the amount in your account on a monthly basis so when tax time comes around you have enough money ready.
Step Three: Add It to Your Budget
Treat your quarterly taxes as any other business expense and incorporate your monthly tax savings into your monthly budget. By doing this, you’ll make sure that you always account for the expense and never fall short. When tax time rolls around you’ll be stress free and in the black.
Saving for your quarterly taxes may not be fun, and there are certainly other things you’d like to do with the money. However, by creating your quarterly tax plan you will remove the stress of paying taxes and you make sure you’re not hit with a large payment (and possibly even financial penalties) at the end of the year.
