For example, a resident with employment income and allowable deductions for health expenses can utilize this mechanism to foresee the impact of these factors on their overall tax burden.
Such a resource provides significant advantages by promoting financial planning and fostering a better understanding of tax obligations. It empowers individuals to make informed decisions regarding their finances and helps them prepare for tax season. Historically, calculating tax liabilities was a complex manual process. The advent of these automated tools has simplified this process, saving time and reducing the potential for errors in tax calculations.
