The answer depends on the source of the money in your account. If it is from profit on a self employed activity, such as your farming activity, then it could be taxable, I say “could” because you may have losses from a previous year that may wipe out the taxable income in the current year. Your accountant is the best person to advise you. The one thing that you must make sure of is that you do not leave yourself exposed to penalties and interest by Revenue down the road.
