Tax Services in London for Small Businesses
London businesses file under the UK's Corporation Tax system, where a marginal relief band sits between the small profits rate and the main rate, so the effective rate a company pays depends on where its profits actually fall, not a single flat number.
VAT registration becomes mandatory once taxable turnover crosses threshold, and getting that registration timed correctly matters since backdated liability can apply if it's missed. Profitjets calculates your effective Corporation Tax rate correctly across the marginal relief band, monitors your turnover against the threshold, and manages filings for your team, so nothing falls through the cracks.

Plan your Corporation Tax & the Marginal Relief
Corporation Tax applies at different effective rates depending on where a company's profits fall relative to the small profits and main rate thresholds, and missing the marginal relief calculation is one of the more common ways businesses overpay.
We calculate your effective rate correctly across the relief band, file your Corporation Tax return with HMRC, and plan ahead around available deductions.

What London Businesses Say
"Our previous accountant filed us at the main Corporation Tax rate without checking whether marginal relief applied. Profitjets recalculated it and corrected two years of overpayment."
"We crossed the VAT threshold mid-year and didn't realize registration should have happened immediately. Profitjets caught it before it became a backdated liability."
"We'd been filing PAYE inconsistently since hiring our first employee. Profitjets set up proper payroll filing and it's been accurate every month since."
