SELF ASSESSMENT FAQS

Self Assessment Tax Return FAQs

These answers are for general information. For a deadline, tax calculation or personal filing decision, contact Phoenix Tax Accountancy for advice based on your records and circumstances.

01Who needs to complete a Self Assessment tax return in the UK?
HMRC uses Self Assessment to collect Income Tax where income is not fully dealt with through PAYE. You must file if HMRC asks you to, and other sources of income can create a filing requirement.
02How do I register for Self Assessment for the first time?
Register through HMRC before your first required return. The route and information needed can depend on whether you are self-employed, a landlord, a company director or have another reason for filing.
03What records do I need for a Self Assessment tax return?
Keep records that support the income, expenses and claims reported on your return, such as invoices, receipts, bank records, CIS statements and property information where relevant.
04What is the online Self Assessment tax return deadline?
Self Assessment filing and payment deadlines can lead to interest or penalties if missed. Check the current HMRC deadline for the tax year and start preparation early.
05Can a landlord use Self Assessment to report rental income?
Rental income may need to be reported through Self Assessment, depending on the individual’s circumstances. Keep rental statements, letting agent information, expenses and property records.
06How do I correct a Self Assessment tax return after filing?
A submitted Self Assessment return can often be amended through the relevant process, but time limits and correction routes apply. Keep a clear record of the original and revised figures.
07What are Self Assessment payments on account?
Payments on account are advance payments toward a future Self Assessment tax bill in certain circumstances. The calculation and whether they apply depend on the previous liability and current rules.
08How do I claim a Self Assessment tax refund from HMRC?
Where a return shows an overpayment, HMRC may offer repayment options. Check the account details, confirm that all information is complete and retain records supporting the figures.
09What should I do if my Self Assessment tax return is late?
Submit the return as soon as possible, deal with any payment position and seek advice if you have missing records or a penalty concern. Delaying usually increases the risk of further charges.
10Can an accountant complete and file my Self Assessment tax return?
Yes. An accountant can organise records, prepare the return, explain the calculation and file with authority, while you remain responsible for reviewing and approving the information.
