Here are four tactical tweaks you might want to consider ahead of potential tax hikes next year.\r\n\r\nBook gains in 2012.\r\n\r\nThe maximum tax hit on long-term capital gains this year is 15%. On January 1 this tax is scheduled to rise to 20% (23.8% if you\u2019re in the\u00a0crosshairs of the Medicare surtax). You never should base an investment decision solely on taxes, but if you\u2019ve been thinking about making a portfolio change, or selling an asset, maybe this is the motivation to get it done before year-end.\r\n\r\nA quick gut check on whether it\u2019s time to sell an investment:\r\n\r\n\tWould you buy the investment at today\u2019s valuation?\r\n\tDoes it still fit your strategy?\r\n\r\nEven if the answer to both is yes, you might still consider selling... and immediately repurchase what you just sold. The 30-day wash-sale rule doesn\u2019t apply to investments you sell at a gain. You are allowed to immediately sell-buy roundtrip any investment that you\u2019ll book a gain on. The advantage is that you\u2019ll pay a top capital gains tax rate of 15% in 2012 on the shares you just sold, and then establish a new cost-basis for the re-bought shares. This strategy works best the shorter your expected holding period (after you repurchase). It\u2019s worth having your tax pro run through some scenarios to decide what makes sense for your particular situation.\r\n\r\nHold off on losses.\r\n\r\nIt gets a little trickier if you have investments currently underwater. Losses can be used to offset gains. But if your losses exceed any gains for a given tax year you can then deduct up to $3,000 of your losses each tax year. That $3,000 might be more valuable next year if you are in a higher tax bracket. If your loss is more than $3,000 you carry that forward into the next tax year (and the year after...) and use it the same way. The one caveat here is if you are going to book any gains in 2012. If that\u2019s the case, you and your tax pro can discuss whether it makes sense to also book a few losses to offset those gains.\r\n\r\nMaximize your tax-advantaged retirement savings.\r\n\r\nLike any 401(k) participant you can contribute up $17,500 in the form of an employee contribution in 2013 into the entrepreneur\u2019s version: the Solo 401(k). But as the employer you\u2019re also allowed to give yourself a profit-sharing contribution of up to 20% of your employment income. The combined value of both contributions is capped at $51,000 in 2013 ($56,500 if you are at least 50 years old). That\u2019s all tax-deductible, and the money grows tax-deferred.\u00a0\r\n\r\nOr you and your tax pro might talk through whether you want to open a Solo Roth 401(k): Current contributions are made after-tax, so there\u2019s no immediate tax break. The payoff: tax-free withdrawals in retirement. Yes, tax free.\r\n\r\nPark income and dividend investments in the right place.\r\n\r\nThe flat 15% tax on qualified dividend income is scheduled to expire at year-end and revert to the old system in which dividends are taxed at whatever your income tax rate is. For some investors that could mean north of 40%. If that tax change plays out, that raises the value of owning dividend-paying stocks (and interest bearing investments that have always been taxed at income tax rates) inside your tax-deferred retirement accounts.
