In a recent tax planning meeting with one of our clients, we shocked them with what their income tax future looked like for 2013 if Congress continues to do nothing to provide a long-term permanent set of tax laws. They had no idea what tax breaks were expiring this year and next year, and how much it would cost them personally in extra income tax. But they aren’t alone, many Americans and even tax professionals aren’t aware that their tax bill could rise dramatically next year.

These clients are your average American family and their situation is a good example of the law changes that will affect all of us. Here’s their tax situation with a table summarizing the expiring tax laws that are scheduled to occur in 2011 and 2012.

Meet the Smiths: 26-year-olds Bill and Joan have been married for five years and have two young children. Bill earns about $65,000 a year in sales and Joan has gone back to work and earns about $35,000 annually. Bill owes quite a bit on his college student loans and will pay about $3,000 in interest on them in 2013. With Joan working again, they are paying $3,000 for year-round child care. Joan inherited some AT&T (T) stock from her grandmother, which pays her $1,000 in dividends every year. Finally, counting home mortgage interest, they have about $20,000 in itemized deductions.

The first big change affecting the Smiths will be a combined increase in income tax rates, and a tightening of tax brackets as a result of the expiration of the Bush tax cuts. We estimate this will cost them $960 in 2013.

Bill will lose the complete deduction of his student loan interest in 2013, costing about $840. The pair’s allowable deduction for child care will drop to $2,400 from $3,000, and they will also see their credit for children drop in half, costing another $1,000.

The marriage tax penalty will come roaring back to hit the Smiths in 2013, costing an estimated $500. The tax on their dividend income will go increase to $280 from $150, adding another $130. Finally, although we did not calculate the effect, without Congressional action to once again "fix" the alternative minimum tax, the Smiths could owe this ugly tax as well!

Luckily for the Smiths--but not for many Americans--other major changes for 2013, which do not personally affect them, include a phase out of itemized deductions and personal exemptions if their income starts to climb.

In summary, because of tax laws expiring this year and next, we estimate that the Smiths will owe $3,598 more in income tax in 2013 than in 2011 with no change in their income.
