In recent years, the Internal Revenue Service (IRS) has been more compliant with working out late tax payments for people living in Lisbon but you have to address dealing with the problem upfront. The IRS offers several programs to choose taxpayers who qualify for tax relief. However, their objective is to obtain as much of the total, including penalties and interest, as possible from the taxpayer. Depending on your financial status and how much money you owe, you may be able to make payments over time, or pay a lesser amount, either in a lump sum or on an installment basis. In some cases, you won't have to pay taxes at all, at least for now, or you can have your back tax obligations permanently forgiven.
