In order to go ahead with a tax filing from a previous year, the first step is to collect all relevant income records of the year in question, e. g., W-2s, 1099s, and expense receipts. Obtain tax forms of the right year by either downloading them from the Internal Revenue Service website or getting the help of a tax software that enables filing of taxes for past years. Fill out the form in accordance with the laws and rates of the particular year. Most tax returns from previous years have to be physically printed and mailed to IRS offices rather than being e-filed. Along with your return, you should also send any taxpaymentst due in order to lessen penalties and interest charges. In case you are eligible for a refund, it is advisable to file within three years of the original deadline. If you have severayears of overdue tax returnsrs, you may want to consult a tax professional.
