The tax overview can only be provided by the HMRC. This is usually requested in addition to your SA302 tax calculation to support a mortgage application.
You can download your HMRC Tax Overview:
2. Click 'View your tax year overview'
3. Select the appropriate tax year and click 'Go'
4. Print your overview to PDF - this should accompany your SA302 tax calculation from the @GoSimpleTax reports page. The tax figures should match on both the tax calculation and your HMRC overview.
If your tax figure doesn't match, your mortgage provider will not accept the documents. If you have not changed your tax return after submitting, you will need to contact HMRC and query with them why there is a difference.
If HMRC have made an amendment, they will send out a tax calculation which supersedes your @GoSimpleTax tax calculation.
