These types of scams ramp up due to it being close to the holiday season. Always try to remember that the Government will not call or text you for these types of matters. They will send you a letter in the mail.
Even if it sounds legit though. Scammers will want to be paid in Visa or MasterCard gift cards. Never give them your actual credit or debit card info because they will tell you it didn't work while they bleed your accounts dry while insisting you pay with Visa or MasterCard gift cards.
