With less than a month remaining until individual tax returns or extensions are due, a couple thoughts come to mind as ways to reduce a tax liability:
Overall, there are other options available but these two are the easiest for individuals to take advantage of, especially when they owe taxes.
Hopefully you have already taken advantage of these programs, but if not and would like more information please contact us.
It's a good time to check up on your W4 withholding allowances, especially if you just completed your taxes and had a very large refund or had tax due. The IRS has a helpful worksheet here: https://www.irs.gov/pub/irs-pdf/fw4.pdf
Since these allowance elections are not retroactive, please keep in mind that we are nearly 3 months into the year. Accordingly, consider modifying your initial results to factor in a "catch-up" component so that your full-year 2018 withholdings meet your expectations.
Feel free to contact me if you have any questions.
