Support 2021


Providing Software Solutions For The Active Family Law Attorney......


Discover absolutely one of the best software tools for evaluating alimony/maintenance claims, and one of the easiest ways for calculating child support based on your state guidelines. We currently offer versions of Support 2021 for the states of Florida, Kentucky, Michigan, Washington and Maryland.


What's New:


The federal tax estimates generated by Support 2021 incorporate the inflation-adjustments provided by the IRS for the 2021 tax filing year - such as the income amounts subject to FICA and self-employment tax, the inflation-adjusted standard deduction amounts and the various inflation-adjusted income tax brackets and phase-outs. The Tax Cuts and Jobs Act, passed by Congress in December of 2017, eliminated personal exemptions, increased standard deductions, reduced tax rates with new income tax brackets and increased the child tax credit which can now be up to $2000 per child (subject to income level phase-outs) with up to $1,400 of that credit refundable beyond taxes owed. More information can be found here: FAQs .


The state tax estimates generated by the Michigan, Maryland, and Kentucky versions use the most currently available inflation adjusted income tax code for those respective states


Starting with the 2019 tax filing year, new alimony/maintenance transfers are no longer a tax deduction from gross income for the payer nor taxable income for the payee. Consequently, the alimony/maintenance routines in the program have been substantially modified. Support 2021 will, though, allow the user to generate an alimony recommendation that is either taxable to the payer (under current tax law) or taxable to the payee (to accommodate modifications of alimony orders originally made before 2019).


Support 2021 includes a dialog for capturing the wages and the pass-through income earned by individuals with ownership in sole proprietorships, partnerships or S-Corps as up to 20% of the income earned from those of types of entities may now be deducted from federal taxable income. Support 2021 provides for the current inflation-adjusted phase-outs and limitations for this business income tax deduction. More information about the business deduction can be found here: New Section 199A Business Deduction
