The review in tax caster is the exact same as figures in Turbo tax, yet tax amount is less in tax caster. The amounts entered are exactly the same from income and deductions.
You are asking from Premier? Do you have investments, rental property, K-1 forms? Taxcaster may not handle those well.
No, just some investments. I did not put those in yet though. The difference was about $1800 in tax more from TT
The TT program is not finalized yet (but be sure to run an update), and I believe Taxcaster doesn't calculate some penalties. Did you take an early withdrawal from a retirement plan for example?
And 30% is relative. For example, $70 v. $100 is not a lot.
To make the estimating simpler, TaxCaster makes various assumptions. TaxCaster generally calculates only income and self-employment taxes. It does not calculate various penalties such as penalties for early distributions from retirement accounts.
Even though 2017 TurboTax is not finalized yet, in most cases 2017 TurboTax will give a more accurate result than will TaxCaster. Errors due to 2017 TurboTax not being finalized will be small in almost all cases since these errors are generally the result of cost-of-living adjustments. (Of course this likely won't be true for 2018 taxes when there will be major changes resulting from the new tax law.)
