Accelerate deductions, harvest losses and time your investment income if you're teetering close to the Medicare surtax line.

Taxpayers who deploy such year-end planning strategies could significantly lower the 2014 tax bite from Uncle Sam. But they'd better act fast.


The deadline for claiming current year deductions, in most cases, is Dec. 31. And it won't be clear which moves you should make until you've completed a thorough financial review, said John Napolitano, a certified financial planner and certified public accountant with U.S. Wealth Management.

In years where tax rates remain unchanged, as they have in 2014, it is generally good policy to defer income and accelerate deductions where possible, assuming your personal income also remained relatively stable.

"It's back to the old-school strategy of accelerating deductions and deferring income," said Napolitano. "With higher rates from last year still in effect, you want to delay as much income as possible."

To that end, taxpayers can defer receipt of year-end bonuses until January, delay stock option exercises and postpone the realization of capital gains from the sale of appreciated assets until 2015.

The self-employed can also delay billings until late December, thereby ensuring that payment will be received next year.

To accelerate deductions into 2014, taxpayers can prepay their 2015 property and state income taxes in December, max out contributions to their 401(k) plan and individual retirement account, prepay their January mortgage payment in December and bundle out-of-pocket medical expenses.

You must fund your 401(k) by Dec. 31 to count as a 2014 deduction, but you can make prior-year contributions to your traditional IRA all the way up to the filing deadline on April 15, 2015. Roth IRAs, which are funded with after-tax dollars, do not provide a tax deduction, but your earnings grow tax-free.


You can also lower your tax burden by channeling your inner philanthropist.

You'll get twice the benefit from your charitable contribution if you donate appreciated stock or property instead of cash.

Not only will you avoid the capital gain, but you'll get to claim a write-off that may be equal to the asset's fair market value, said Roger Oprandi, a certified financial planner with Ameriprise Financial Services.

"If you have highly appreciated stock, it's a wonderful way to donate to charity," he said.

Retirees age 70½ and older can also satisfy their annual minimum distribution requirement by donating up to $100,000 to charity directly from their IRA.
