Claim all the deductions you've earned Be sure you're deducting every cent you can according to IRS guidelines for small businesses.

I recommend:  Start with the business expenses page at the IRS Small Business and Self-Employed site. Check the list of business tax credits. Take a self-paced online tutorial on tax prep for business. And if you discover you previously missed something, file an amended return, correct your mistake, and request a refund.

Make electronic tax payments Avoid potential penalties and spend less time completing and mailing IRS paperwork by filing electronically. E-file makes it easy.

I recommend:  Check the list of payments accepted online. Then sign up with TurboTax or the IRS to file your return, or register with the electronic federal tax payment system (EFTPS) for recurring online tax payments.

Find the right form Not sure which IRS form you need, or how to complete it? Virtually any IRS form, guide, or publication can be found and downloaded at the IRS website.

I recommend:  Scan the complete list of small business forms or just the list of forms relevant to starting and operating a business.

Access a tax-related checklist for starting your business Discover tax insights on operating a business with employees, deductions and credits, recordkeeping and accounting methods.

I recommend:  See what new business owners need to know about federal taxes.
