This involves obtaining a Unique Taxpayer Reference (UTR) and setting up your online account. Ensure all personal details are accurate to avoid processing delays.

Step 2: Gather Necessary Documentation

Collect all necessary documentation, including P60s, P45s, business income records, and expense receipts. Accurate record-keeping is essential and can simplify the filing process. Ensure all documents clearly reflect your financial activities within the tax year to substantiate your claims.

Step 3: Complete the SA100 Form
