Once you've got all your information in front of you - W-2s, 1099s, Social Security numbers for everybody involved, all of the personal information including addresses, etc. - you also need bank account details and a list of all potential deductions and other sources of income. Now, you have a decision to make regarding how you want to file your taxes. Do you want to use a tax professional to e-file? Or, would you prefer using your personal computer and tax software? Alternatively, you can utilize the IRS website. Depending on your choice, if you opt for a tax preparer, you will provide them with all your information and they will handle the filing process. If you choose pre-packaged software like TurboTax or similar, you will be guided through the process of completing your return and shown how to e-file it. If you decide to file through the IRS website, simply go to their website, click on the appropriate links, and they will effectively guide you throughout the process.
