You can file taxes for your LLC yourself using accounting software or a manual spreadsheet, or you can hire a tax preparer to do the work for you. Doing taxes for an LLC is often a complicated process with many different forms to keep track of and file, and it’s easy to make errors that might result in unexpected tax liabilities or even penalties. A tax preparer is a trained professional who is well-versed in everything an LLC needs to file taxes. However, the cost of using an accountant or preparer can run into the hundreds or even thousands of dollars, depending on the complexity of your LLC’s taxes.
