I recently updated my tax calculator. The latest version includes the new tax brackets and credits according to 2014.
The Israeli Tax Calculator allows you to check your paycheck and see that the correct taxes were deducted correctly. If too much money is being taken out for taxes or insurance, then you should demand back your money through a tax alignment (תאום מס) or an insurance alignment (תאום ביטוח לאומי). If you need to get money back through an alignment see this post for more details.
Note: While the amount for insurance should match your paycheck perfectly, the amount you pay for taxes may not. There are other factors besides the ones mentioned in this spreadsheet that can affect the amount of taxes you pay (how much you got paid over the past 6 years, how often you get paid.)
Use the guide as follows:
If you are paying less in taxes than what is calculated on the sheet: Find out what kind of benefits you are receiving and how to continue receiving them.
If you are paying more in taxes than what is calculated on the sheet: Odds are you need to do a tax alignment. Speak to your HR person and fix up your tax record and then file the appropriate paperwork at מס הכנסה.
As always, if you find any flaws in these excel sheets or have any ideas for improving them, please feel free to contact me.
