The F&C Pacific Investment Trust Board will make a special dividend payment on April 2nd instead of one at the end of the tax year.
The company will pay of 1.05p per share because dividend tax credit will be removed for equity ISA and PEP holders at the end of the tax year.
Buy paying early investors will still receive this benefit.
Christopher Purvis, chairman of F&C Pacific Investment Trust, said: "Paying a dividend in this tax year means that ISA and PEP investors will benefit from the tax credit on the dividend.
"Many investors have built up large portfolios by investing the maximum annual allowance in PEPs and ISAs and dividend income from the portfolio can be significant."
