Choose a US or UK personal plan first. Business add-ons are selected during onboarding — not purchased separately.
At the entity step, choose your single-member LLC, LLC partnership, S-Corp, Ltd, or LLP. The add-on price is shown alongside your personal plan total.
Provide your entity registration, prior-year return (if any), and income/expense records. A licensed professional reviews both returns together.
Your personal and business returns are coordinated and filed in a single engagement. No separate workflows or accountants to manage.
Business Add-On Pricing
Add-ons are priced per entity type and purchased alongside a personal plan.
Frequently asked questions about business entity filing
Does a business add-on replace the personal package?
No. Every business add-on is purchased alongside a personal tax package. The add-on covers the extra forms your business entity requires; your personal return (1040, Self Assessment) is handled by the personal package.
What if I have a US LLC but I live abroad?
A US LLC owned by a non-resident must file Form 5472 and may have FBAR obligations. Our add-ons cover Schedule C and Schedule SE for single-member LLCs, or Form 1065 for multi-member LLCs. We'll clarify your specific structure during onboarding.
My business structure is complex — can you still help?
For straightforward LLCs, Ltd companies, and LLPs we offer fixed-price add-ons. For holding companies, trusts, tiered structures, or foreign corporations, the filing complexity exceeds our productised service — please get a custom quote and we'll design an engagement that fits.
What US forms are covered by the LLC Partnership add-on?
Form 1065 (US Return of Partnership Income) plus K-1 preparation for each partner. The add-on assumes a simple pass-through structure; we include up to two Schedule K-1s. Larger partnerships or complex allocations may require a custom engagement.
What does the UK Ltd add-on cover?
CT600 (Corporation Tax Return) for a standard UK Private Limited Company. This is the corporate tax return filed with HMRC, separate from your personal Self Assessment. Director loan account, dividends, and basic payroll records are included; R&D claims or group structures require a custom engagement.
Is HMRC Enquiry Protection available for business filings?
HMRC Enquiry Protection covers professional costs if HMRC opens a formal enquiry into a return we prepared. It is available as part of the UK Plus personal package and can be discussed for business filings — ask at onboarding.
