How to do Tax Day right

April 15 is tax day, the last day to file taxes without penalties. According to the postal service, tax returns are considered on-time if they're addressed correctly, have enough postage and are postmarked by tax day. For those whose returns didn’t make the cut, the IRS can enforce penalties. The fee for filing late is usually 5 percent of the unpaid taxes for each month the return is late, and won’t exceed 25 percent of unpaid taxes. Failing to pay by the tax deadline results in a penalty of half a percent of the unpaid taxes each month after the due date. According to personal finance website WalletHub, the average American spends 11 hours and $200 to complete an annual income tax return form.
