Know Your Penalty Before the IRS Calls

The Internal Revenue Service is going to outsource some of its delinquent debt to four private debt collection companies for 2016 individual returns. Unlike IRS agents, these companies will have free rein to chase down overdue payments, including your tax penalty. We thought it would be helpful for you to understand how the IRS calculates some of its most common penalties, so you are forewarned before receiving a call from these private agents.

Getting the Most From Your Out-of-Pocket Expenses

When you go on a business trip or take a client out to lunch, you can generally count on your employer to pick up the tab. Depending on your profession and employer, however, there may be times when you’re forced to pay a business expense out of pocket. Even if the company isn’t paying you back, you shouldn’t throw away the receipts – you may be able to deduct those expenses on your individual tax return.
