Processing the S-Corp election typically takes about 60 days from the date the IRS receives your Form 2553 (Election by a Small Business Corporation). However, processing times can vary depending on factors like the time of year and IRS workload. It’s important to submit the form within 75 days of forming your business or at the start of a new tax year to ensure timely approval. If there are any issues or missing information, the IRS will notify you, which could extend the process.
