UK tax returns,
refunded in full.
Filing an annual Self Assessment is a statutory obligation for every self-employed individual working in the United Kingdom. In many cases, employed individuals on PAYE are also entitled to recover overpaid tax — typically for up to four previous tax years.
IB Service is an HMRC-approved practice. Our specialists apply every allowance and relief available to you, file your return promptly and pursue the full refund you are due — without unnecessary correspondence or delay.
