When your resolution this year is to avoid paying tax penalties your best options are to have everything in on time and to have year-round accounting so that you don’t have a mad dash to have everything in order by the last minute. To help make sure nothing slips through the cracks this year, I have provided a simple calendar for your business and personal tax returns. To be clear, this calendar is for businesses that operated on a calendar year, meaning their fiscal year ends on December 31st then this calendar is for you. If your business does NOT operate on this calendar, give me a call so I can help plan your year so that you can avoid any tax penalties.

Should you consider a tax extension for 2018?

If you didn’t hire me to regularly prepare your books in 2017, you might be behind in getting them organized. Whatever your case may be, you can extend your tax return deadline if you truly need the extra time to assure that absolutely everything is taken care of and in order so that your deductions are maximized and you avoid tax penalties.
