Everyone in this world love to make money. People are ready to do anything for money. All of us will work hard to earn money. When people start earning more, they have to pay tax to the government. The tax is calculated on percentage of the income and the tax percentage will vary with the income. Government is providing some tax exceptions to the tax payers for the money they spend for good purpose like charity and for the investment in shares, in investment plans and in loans. Many people will forget to pay the tax on time. They may be in out station or they may stick with some other works. For those people, government is providing federal tax extension to pay the tax. We should pay the tax within the extension date. Before paying the tax, we need to calculate the tax amount to be paid to the government. We can calculate the federal tax with the help of tax auditors. Auditors will calculate the tax with the deductions from the gross salary. The calculations will be accurate and you can save more money in the tax. You can get the advice from the auditors to invest money in the investment plan. When you could not able to pay the tax at time, you will get the extension date for tax filling from the auditors. Pay your taxes within the extension time and avoid late pay fine.
