Proposals to reform retirement savings plans were highlighted during an April 2012 hearing by the House Ways and Means Committee. Lawmakers were advised by many experts to move slowly on making changes to current retirement programs that might discourage employers from sponsoring plans for their workers. Nevertheless, it is clear that Congress wants to make some bold moves in the retirement savings area of the tax law and that likely it will do so under the broader umbrella of general "tax reform." While tax reform is gaining momentum, it is unlikely to produce any change in the tax laws until 2013 or 2014. Considering that retirement planning necessarily looks long-term into the future, however, now is not too soon to pay some attention to the proposals being discussed.

Your 2011 tax return has been filed, or you have properly filed for an extension. In either case, now it's time to start thinking about important post-filing season activities to save you tax in 2012 and beyond. A few loose ends may pay dividends if you take care of them sooner instead of later.

A disregarded entity refers to a business entity with one owner that is not recognized for tax purposes as an entity separate from its owner. A single-member LLC ( "SMLLC"), for example, is considered to be a disregarded entity. For federal and state tax purposes, the sole member of a SMLLC disregards the separate legal status of the SMLLC otherwise in force under state law.

Building on earlier steps to help taxpayers buffeted by the economic slowdown, the IRS recently enhanced its "Fresh Start" initiative. The IRS has announced penalty relief for unemployed individuals who cannot pay their taxes on time and has increased the threshold amount for streamlined installment agreements.

The just-released 2011 IRS Data Book provides statistical information on IRS examinations, collections and other activities for the most recent fiscal year ended in 2011. The 2011 Data Book statistics, when compared to the 2010 version, shows, among other things, a notable increase in the odds of being audited within several high-income categories.

The IRS reopened its offshore voluntary disclosure program in early 2012 in response to what the government described as strong interest among taxpayers. The reopened program, the third of its type in recent years, encourages taxpayers with unreported foreign accounts to make full disclosures in exchange for a reduced penalty framework. Like its predecessors, the terms and conditions of the reopened program are very complex. The IRS has promised to provide more details. In the meantime, the prior offshore disclosure programs are guides to how the IRS intends to implement the third, reopened program.

The IRS has released much-anticipated temporary and proposed regulations on the capitalization of costs incurred for tangible property. They impact how virtually any business writes off costs that repair, maintain, improve or replace any tangible property used in the business, from office furniture to roof repairs to photocopy maintenance and everything in between. They apply immediately, to tax years beginning on or after January 1, 2012.

The business standard mileage rate, which many employers use to reimburse employees for business miles driven, is 55.5 cents-per-mile for 2012, the IRS has announced. This reflects no change from the second half of 2011.

Claiming a charitable deduction for a cash contribution is straightforward. The taxpayer claims the amount paid, whether by cash, check, credit card or some other method. Taxpayers need only a bank record or a written acknowledgment from the charity. For contributions of property, the rules can be more complex.

After three days of oral arguments in March, the Supreme Court is deciding the fate of the Pension Protection and Affordable Care Act (PPACA) and its companion law, the Health Care and Education Reconciliation Act (HCERA). Not only do the new laws impact health care, they contain numerous tax provisions, many of which have yet to take effect. The Supreme Court may uphold the laws, strike them down in whole or in part, or decide that the case is premature. The Supreme Court is expected to render its decision in June. In the meantime, a quick checklist of the tax provisions in the two laws reveals how extensively they impact individuals, businesses and taxpayers of all types.
