The arrival of a new season comes amid the heart of tax season, which makes now a great time to conduct spring cleaning for your money.

TAXES If you received a tax refund of more than $1,000, your first task is to adjust your withholding. Remember, a refund is the return of a yearlong, interest-free loan that you extended to Uncle Sam, so let's not do that again! If you need help determining the proper withholding amount, the IRS has a nifty calculator at

Once you adjust, you will have more money in each paycheck. It is critical that you take the extra amount and save it. The easiest way to do so is to boost your retirement contributions into your employer-sponsored plan or to establish an automatic monthly draft from your checking or savings into a traditional or Roth IRA.

INVESTMENTS Something else you may have discovered in the process of preparing your returns is the tax inefficiency of many mutual funds. If you own funds in taxable accounts, you are whacked with two types of taxable distributions: ordinary dividends and capital gains distributions. To minimize the effect of the latter, you may want to examine your fund's turnover ratio, which measures how much the fund manager buys and sells assets in the portfolio. A 100 percent turnover means the portfolio is changed completely in one year. The higher the turnover, the more taxes you will pay. Another way to minimize taxes — and actually pay lower fees — is to stick to low-cost index funds.

As we approach the end of the quarter, don't forget to rebalance your accounts so that your allocation remains in check. This requires that you override your emotional urge to keep winners and dump losers. But that's the point of asset allocation — the various funds are supposed to move in different directions at different points in the economic cycle. If your retirement plan allows, elect auto-rebalancing so you don't have to worry about doing it manually. Otherwise, put a reminder on your calendar for June 30, Sept. 30 and Dec. 30.

REAL ESTATE The spring real estate season is a good reminder that you need to take care of one of your most valuable assets: your home. Make sure that your property/casualty insurance is up to date and then start making the list of maintenance items that you need to address, especially those that may have occurred as a result of winter conditions.

If you are ready to tackle some larger projects, prioritize them by choosing those that add the most value to your home. According to Remodeling magazine's 2015 Cost vs. Value Report, "replacement jobs — such as door, window and siding projects — generated a higher return than remodeling projects." The good news is that simple and lower-cost projects can provide you with a big bang for your buck.

REFINANCING Finally, with conventional mortgage rates at relatively low levels, new lower pricing on FHA loans and home prices continuing to advance, it may be a good time to determine whether refinancing your mortgage makes sense.

According to Mike Raimi of Luxury Mortgage Corp, if you are looking for a 30-year conventional mortgage with 20 percent down, the best rates are available for those with credit scores above 740. For every 20-point drop in score, the mortgage rate jumps by a quarter of a percent. If your credit score is below 620, it's tough to get a loan closed. (Credit scores do not have nearly as much impact on loans of 15 years and shorter.)
