Zipp Tax is an accountancy practice, not HMRC.
How a tax rebate works
Zipp Tax is an accountancy practice. A qualified accountant prepares your full tax return and files it with HMRC as your authorised agent. A tax rebate is the result of that return.

When Self Assessment is the route
Self Assessment is how HMRC collects tax that is not fully taken through payroll. You may need to file a return if you:
- are self-employed or run a business
- have rental or other untaxed income
- receive income from abroad
- have been asked to file by HMRC
Some people also file a return to include allowable expenses and reliefs on their own tax position. Whether it applies to you depends on your circumstances.

Any questions?
Am I due a tax rebate?
Only your full tax position can show that. A tax return adds up your income, the tax already paid, allowable expenses and reliefs. If you have paid more tax than the return shows, the difference can be repaid. Many returns show no repayment, and some show tax to pay.
Do I need to file a tax return?
It depends on your circumstances. People who are self-employed, have rental or other untaxed income, or have been asked by HMRC usually need to. If you are unsure, we can tell you.
What is Self Assessment?
Self Assessment is the system HMRC uses to collect tax that is not fully taken through payroll. You report your income and allowable expenses for the tax year in a tax return.
What does Zipp Tax do?
We are an accountancy practice. A qualified accountant prepares your Self Assessment return and files it with HMRC as your authorised agent.
Is Zipp Tax part of HMRC?
No. Zipp Tax is an independent accountancy practice and is not affiliated with HMRC or the UK government. You can deal with HMRC directly, free of charge, at gov.uk.
How much does it cost?
Our accountancy fee is 37.5% + VAT of the tax relief we secure, with a minimum of £99 + VAT. Nothing to pay upfront. For example, £1,000 of relief means a £375 + VAT fee.
