The Tax Reform Calculator is a sister site to the Tax Form Calculator which has supported free tax return calculations and salary estimates since 2010. In 2017, Donald Trump, 45th President of the United States announced plans for sweeping tax reforms. The aim of the tax reforms being to simply tax for average Americans, reduce the tax burden for working families and make tax more transparent and easier for businesses. These three aims being part of President Trumps aim to boost the American economy, improve business growth in America and provide a better quality of life for American families.

We all agree those are great aims to have, a strong economy and reduced taxes and good for families and business alike but what Politicians promise and deliver are not always the same thing. The important question is:

What will the tax reforms really mean to you?

Since 2010, we have provided tools which provide a detailed breakdown of tax calculations to allow a clear view of how key payroll taxes are calculated. In this special site setup for the tax reforms, we provide a set of calculators and tools that will allow you to enter your salary or taxable amount (depending on the tax reform calculator you are using) and calculate the new tax commitments under the tax reform legislation.

For transparency, the tax reform calculator will provide an example of your tax return calculation under the current tax law and also under the planned tax law once tax reforms come into place. The tax reform calculator will also show you how much better or worse off you will be after the tax reform legislation comes into place.

The tax Reform Calculator is updated as the tax laws change so you can check back as tax reforms solidify, make a quick tax calculation and email/print it for your reference or discussion on tax blogs, tax websites etc. You can also add a copy of the Tax Reform Calculator to your won website to allow your users to use the tool whilst browsing your tax advice, tax refund articles etc.

Tax Reform Update

20th December 2017 The Final Republic Tax Reform figures where presented and approved. These figures have been integrated into the tax reform calculator. You can see how income tax calculations will look under those reforms by selecting 'Final' from the 'Calculation Type' options. We have retained the original planned, House and Senate proposals to allow visibility of how the changes played out and to compare the relative tax amounts in each proposal side by side. To view the tax reform comparison, select 'Combined' calculation type.
