I believe the IRS is supposed to put out a calculatorsoon but you can find synopses of the law changes online easily enough. Takeyour 2023 return and recalculate using the 2023 changes and you will know whatyour tax bill will be at the end of the year.

If you are selfemployed live in a hightax state or have a veryhigh income there are other changes that may impact you. The tax bracketschanged as well.If you are comfortable with spreadsheets you can replicate your 2023 returnand then create a 2023 version using the new rules to compare thedifference.Alternatively see a CPA or financial advisor who can do the work for you.
