Frequently asked questions
What is a UTR number and how do I get one?
Your Unique Taxpayer Reference (UTR) is issued by HMRC when you register for self-assessment. You can retrieve it via HMRC online services or by calling their helpline.
Do I need to file a self-assessment tax return?
You must file a self-assessment if you’re self-employed, a company director, have rental income, or other untaxed income. We handle self-assessment tax return filing and HMRC registration.
What does PAYE mean?
PAYE (Pay as You Earn) is HMRC’s system for collecting Income Tax and National Insurance from employees. Employers must submit RTI payroll data monthly.

Your Corporation Tax return (CT600) is due 12 months after your accounting period ends, but tax must be paid 9 months and 1 day after. We ensure no missed deadlines.
How do I register for VAT?
If your turnover exceeds the VAT threshold, you must register with HMRC. We help with VAT registration, filing MTD VAT returns, and ongoing bookkeeping.
Can I get a mortgage if I’m self-employed?
Yes, with the right paperwork. We prepare mortgage accounts, self-employed tax returns, and liaise with mortgage brokers for smooth approval.
What is the Let Property Campaign?
It’s an HMRC initiative allowing landlords to disclose undeclared rental income with reduced penalties. We handle disclosures under the Let Property Campaign.
