It’s best to remain organized all year, collect all W2s, 1099s, receipts, payroll records and business documents in one place and file and pay via the official IRS website or tax software that you trust. When you’re sent a notice by IRS, do not ignore it. Carefully review the issue, collect supporting documents and reply before deadline.
