Doing your own taxes by yourself is actually easier than most people think, but it does require strict following of instructions or else everything can be mixed up and sent off incorrectly. Typically, filing your own taxes requires you to be organized with all the proper documents (last year's return and other tax-related documents), and good time management which means don't procrastinate on your tax returns. Then, you would need to cross examine all documents to make sure all information is filled out correctly in the right places. Make sure all documents are e-file accessible, meaning they can be sent off and opened through any type of computer and/or processing machine online. And lastly, make sure you look through all documents several times to make sure no mistakes are made.
