8 Tax Mistakes You Can’t Afford to Make: Annaly Capital Management, Inc. (NLY), American Capital Agency Corp. (AGNC)

Recommendation: Be sure to consider special tax rules for certain investments

For instance, precious-metals investors need to be aware that because of their structure, SPDR Gold Trust (ETF) (NYSEARCA:GLD) and iShares Silver Trust (ETF) (NYSEARCA:SLV) have their gains taxed as collectibles, which carries a higher rate on capital gains even if you hold the shares for more than a year.

Selling too soon after receiving a dividend can take away the lower tax rate on your payout.

Bottom line: Be careful before you sell.
