Tax Preparation Services in the United Kingdom
UK tax compliance spans Corporation Tax (CT600), Self Assessment (SA100), VAT under Making Tax Digital, PAYE via Real Time Information (RTI), and Construction Industry Scheme (CIS) returns — all administered by HMRC.
UK tax compliance spans Corporation Tax (CT600), Self Assessment (SA100), VAT under Making Tax Digital, PAYE via Real Time Information (RTI), and Construction Industry Scheme (CIS) returns — all administered by HMRC. Fintax Support Limited prepares and files CT600 returns with iXBRL tagged accounts, manages quarterly VAT returns through MTD-compatible software, and handles SA100 personal tax returns for directors and sole traders. We optimize capital allowances, R&D tax relief under HMRC's SME scheme, and ensure CIS deductions are correctly offset against your tax liability.
Regulatory Framework
Corporation Tax returns (CT600) are due 12 months after the accounting period end, but tax must be paid nine months and one day after period end. VAT returns are typically due one month and seven days after the quarter end under MTD. Self Assessment SA100 is due 31 January following the tax year, with payments on account due 31 January and 31 July.
Our Tax Preparation Services in United Kingdom
Corporation Tax Returns (CT600)
Prepare and file CT600 Corporation Tax returns to HMRC with iXBRL-tagged statutory accounts attached. UK limited companies must submit CT600 within 12 months of accounting period end, while Corporation Tax payment is due nine months and one day after period end — we reconcile taxable profit, capital allowances, and R&D relief before filing.
CT600 with iXBRL accounts
Corporation Tax return prepared with iXBRL-tagged FRS 102 or FRS 105 accounts submitted electronically to HMRC.
Taxable profit computation
Book profit adjusted for disallowed expenses, capital allowances, and brought-forward losses on CT600 schedules.
Dual deadline tracking
CT600 filing due 12 months after year-end; Corporation Tax payment due nine months and one day after period end.
Penalty avoidance
Automatic HMRC penalties for late CT600 filing start at £100 — we track both filing and payment deadlines.
How It Works
Accounts and trial balance review
Review statutory accounts, adjusted trial balance, and prior-year CT600 for brought-forward losses and capital allowances.
Tax computation and CT600 preparation
Compute taxable profit, apply capital allowances and R&D relief, and complete CT600 with supporting schedules.
iXBRL tagging and client approval
Tag accounts in iXBRL format, attach to CT600, and walk through tax liability and payment date with directors.

Every UK limited company must file a CT600 Corporation Tax return to HMRC within 12 months of its accounting period end, with iXBRL-tagged statutory accounts attached. Corporation Tax payment is due earlier — nine months and one day after period end — creating a cash-flow gap directors must plan for. We compute taxable profit by adjusting book profit for disallowed expenses such as client entertainment, apply the Annual Investment Allowance and writing-down allowances on qualifying plant and machinery, and offset brought-forward trading losses where permitted. Companies with taxable profits above £1.5 million pay Corporation Tax in quarterly instalments during the accounting period. Late CT600 filing triggers automatic HMRC penalties starting at £100, escalating to £500 after three months. Our CT600 preparation aligns with Companies House accounts filed under FRS 102 or FRS 105 so statutory and tax filings remain consistent.
Common Questions
Self Assessment Tax Returns (SA100)
File SA100 Self Assessment tax returns for directors, sole traders, partners, and landlords with all supplementary pages completed accurately. The SA100 deadline is 31 January following the tax year end — we report employment income, dividends, self-employment profits, and property income with correct HMRC tax codes and reliefs applied.
Directors and sole traders

Self Assessment requires individuals with income not fully taxed at source — including company directors receiving dividends, sole traders, partners, and landlords — to file an SA100 return by 31 January following the tax year ending 5 April. Supplementary pages cover employment (SA102), self-employment (SA103), partnerships (SA104), UK property (SA105), and foreign income (SA106). We reconcile P60 employment income against P11D benefits, apply the dividend allowance and basic or higher rate tax bands, and calculate Class 2 and Class 4 National Insurance on self-employment profits. Payment on account — advance payments toward the following year's liability — is due 31 January and 31 July. Late SA100 filing incurs an immediate £100 penalty, rising to £500 after three months. Making Tax Digital for Income Tax Self Assessment (MTD ITSA) will require quarterly digital updates from April 2026 for qualifying self-employed individuals and landlords.
Common Questions
VAT Returns (MTD-Compliant)
Prepare and submit quarterly VAT returns through Making Tax Digital-compatible software with digital links from source records to HMRC. MTD for VAT requires VAT-registered businesses to keep digital records and file returns via recognised software — we reconcile output and input VAT and submit directly to HMRC each quarter.
MTD quarterly submission
VAT returns submitted quarterly through MTD-compatible software with digital links from bookkeeping to HMRC.
Output and input VAT reconciliation
Sales and purchase VAT reconciled to nominal ledger with correct treatment of standard, reduced, zero-rated, and exempt supplies.
HMRC-recognised software
Returns filed via Xero, QuickBooks, Sage, or FreeAgent — all MTD-compatible with direct HMRC submission.

Making Tax Digital for VAT requires all VAT-registered businesses to maintain digital records and submit VAT returns through MTD-compatible software with digital links between data — meaning figures cannot be manually copied from spreadsheets into bridging software. Returns are filed quarterly (or monthly for businesses on monthly accounting) with payment due one month and seven days after the VAT period end. We prepare returns on Xero, QuickBooks Online, Sage Business Cloud, or FreeAgent, reconciling box 1 output VAT on standard-rated, reduced-rated, and zero-rated supplies against box 4 reclaimable input VAT. Special schemes including Flat Rate Scheme, Cash Accounting Scheme, and Annual Accounting Scheme are reviewed for continued suitability. Post-Brexit rules for goods imported from the EU and Northern Ireland protocol transactions require correct reverse charge and postponed VAT accounting treatment on each return.
Common Questions
PAYE & Real Time Information (RTI) Submissions
Manage PAYE payroll and submit Real Time Information Full Payment Submissions to HMRC on or before each payday. RTI reporting replaced annual P35 returns — every payment to employees must be reported to HMRC in real time, and we handle FPS submissions, EPS adjustments, and year-end reconciliation.
RTI on every payday
Full Payment Submissions sent to HMRC on or before each payday with accurate pay, tax, and NI deductions.
PAYE and NI calculations
Income tax via PAYE and employee/employer National Insurance calculated using current HMRC tax codes and rates.
Year-end EPS and P60s

Auto-enrolment compliance
Workplace pension contributions calculated and submitted alongside RTI payroll for auto-enrolment compliance.
How It Works

Real Time Information (RTI) requires employers to report pay, tax, and National Insurance deductions to HMRC via Full Payment Submissions (FPS) on or before each payday — replacing the old annual P35 return. We process payroll on HMRC-recognised software, applying tax codes from P6/P9 notices, calculating PAYE income tax and Class 1 employee and employer National Insurance, and handling student loan and postgraduate loan deductions. Employer Payment Summary (EPS) submissions report statutory payments, apprenticeship levy, and claim employment allowance where eligible. Monthly PAYE and NI remittances are due to HMRC by the 22nd of the following month (19th if paying by post). Year-end obligations include issuing P60 certificates to employees by 31 May, filing P11D benefit forms for directors and employees receiving benefits in kind, and submitting the final FPS for the tax year.
Common Questions
CIS Monthly Returns & Subcontractor Verification
File CIS monthly returns to HMRC and verify subcontractor registration status through the HMRC CIS online gateway before making payments. Contractors in construction must deduct tax at source from subcontractor payments — we manage verification, deduction calculations, and monthly CIS300 returns.
CIS monthly return filing
CIS300 monthly returns submitted to HMRC detailing all subcontractor payments and deductions for the period.
Subcontractor verification
Subcontractor UTR and registration verified via HMRC CIS online gateway before first payment each tax year.
Deduction rate application

Payment and deduction statements
CIS deduction statements issued to subcontractors for offset against their SA100 Self Assessment liability.
How It Works

Subcontractor verification
Verify each subcontractor's UTR and CIS registration via HMRC gateway before making first payment in the tax year.
Monthly deduction and CIS300 filing

Year-end reconciliation
Reconcile total CIS deductions against HMRC records and support subcontractors with SA100 CIS credit claims.
The Construction Industry Scheme (CIS) requires contractors to deduct tax at source from payments to subcontractors for construction work and report these deductions to HMRC via monthly CIS300 returns. Before paying a subcontractor, you must verify their UTR and CIS registration status through the HMRC CIS online gateway — registered subcontractors are taxed at 20%, while unverified subcontractors face a 30% deduction rate. CIS deductions apply to the labour element of invoices, excluding materials and VAT. Monthly CIS300 returns are due by the 19th of the month following the reporting period, with CIS deductions remitted to HMRC by the same date. Subcontractors receive deduction statements to offset CIS tax deducted against their SA100 Self Assessment liability. We manage the full CIS cycle from gateway verification through monthly filing, ensuring contractors avoid HMRC penalties for late returns or incorrect deduction rates.
Common Questions
Capital Gains Tax Reporting
Report capital gains on disposals of assets including shares, business premises, and residential property with correct CGT calculations and reliefs applied. UK residential property disposals require reporting to HMRC within 60 days of completion — we calculate gains, apply Business Asset Disposal Relief, and file required returns.
CGT computation
Chargeable gains calculated on shares, property, and business assets with allowable costs and indexation where applicable.
60-day property reporting

SA100 integration
Integrate capital gains into the full SA100 Self Assessment return for the tax year with consistent reporting.
Capital Gains Tax applies when you dispose of chargeable assets including shares, commercial property, and residential property at a profit above the annual exempt amount (£3,000 for 2024/25). Residential property disposals by UK residents must be reported to HMRC within 60 days of completion via the CGT on UK property service, with tax paid within the same window — this applies even if the full SA100 is filed later. Business Asset Disposal Relief reduces CGT to 10% on qualifying business disposals up to a £1 million lifetime limit. Basic rate taxpayers pay 10% on gains within the basic rate band and 20% above for most assets; residential property gains attract 18% and 24% rates. We calculate gains with allowable acquisition and improvement costs, apply Private Residence Relief on main residences, and ensure 60-day reporting deadlines are met to avoid HMRC penalties and interest on late payment.
Common Questions
R&D Tax Credits Claims
Prepare and submit R&D tax relief claims under HMRC's SME scheme or Research and Development Expenditure Credit (RDEC) for qualifying innovation projects. SME R&D relief allows up to 27% effective benefit on qualifying expenditure — we identify eligible projects, compile technical narratives, and file claims with your CT600.
SME scheme vs RDEC
Correct scheme selected — SME enhanced deduction and payable credit, or RDEC at 20% for larger companies and subcontractors.
Technical narrative preparation
HMRC-compliant technical report documenting scientific or technological advance and uncertainty overcome.
Qualifying expenditure analysis
Staff costs, subcontractor payments, software, consumables, and externally provided workers assessed for eligibility.
HMRC enquiry defence
Robust claim documentation prepared to withstand HMRC R&D enquiry and compliance checks.
How It Works

Review company size, connected entities, and project activities to determine SME scheme or RDEC applicability.
Project identification and narrative
Identify qualifying R&D projects and prepare technical narrative documenting advance sought and uncertainties faced.
Expenditure compilation and claim calculation

CT600 integration and HMRC submission
Include R&D claim in CT600 Corporation Tax return and submit supporting narrative to HMRC.
HMRC offers two R&D tax relief schemes: the SME scheme providing an enhanced deduction of 86% on qualifying expenditure (generating up to 27% effective benefit for profitable companies or payable tax credits for loss-making SMEs) and RDEC at 20% of qualifying costs for large companies, SMEs subcontracted to large companies, and grant-funded projects. Qualifying R&D must seek an advance in science or technology by resolving scientific or technological uncertainty — routine development does not qualify. Eligible costs include staff wages, employer NI and pension, subcontractor payments (65% under SME scheme), software, consumables, and externally provided workers. From April 2024, merged R&D relief rules apply with enhanced scrutiny on overseas expenditure and mandatory pre-notification for first-time claimants. We prepare HMRC-compliant technical narratives and integrate claims into CT600 filings to maximise relief while maintaining defensible documentation.
Common Questions
Non-Resident Landlord Tax Returns
Manage UK rental income tax compliance for non-resident landlords including NRL scheme registration, quarterly payments, and annual SA105 returns. Non-resident landlords can apply under Section 216 of the Income Tax Act 2007 to receive rent gross — we handle HMRC registration, tenant/agent obligations, and Self Assessment filing.
Non-Resident Landlord Scheme
NRL scheme compliance managed — tenants or agents deduct basic rate tax unless Section 216 approval is in place.
Section 216 gross payment approval
Application to HMRC for approval to receive UK rental income without NRL tax deduction at source.
SA105 property reporting
UK rental income and allowable expenses reported on SA105 supplementary pages with correct tax treatment.
Double taxation relief
UK tax liability analysed against home country tax obligations with double taxation treaty relief applied where available.
How It Works

Advise UK tenants or managing agents on NRL obligations and provide approval reference for gross rent payments.
Rental accounts and SA105 preparation

SA100 filing and tax payment
File SA100 Self Assessment by 31 January with UK rental tax liability calculated and payment arranged.
Non-resident landlords earning UK rental income are subject to the Non-Resident Landlord (NRL) scheme, which requires UK tenants or letting agents to deduct basic rate income tax (20%) from rent and pay it to HMRC quarterly unless the landlord holds Section 216 approval. Section 216 of the Income Tax (Earnings and Pensions) Act 2007 allows non-resident landlords to apply to HMRC for approval to receive rental income gross without NRL deductions, provided their UK tax affairs are up to date. Landlords must still file an SA100 Self Assessment return with SA105 property pages reporting UK rental income and allowable expenses by 31 January following the tax year. Double taxation treaties between the UK and the landlord's home country may reduce or eliminate UK tax liability. We manage NRL registration, Section 216 applications, coordination with UK managing agents, and annual SA100 filing for overseas landlords.
Common Questions
Tax Planning for Sole Traders, Partnerships & Ltd Companies

Effective UK tax planning requires understanding how income tax, Corporation Tax, and National Insurance interact across sole trader, partnership, and limited company structures. Owner-managed companies often benefit from a combination of salary up to the NI primary threshold or personal allowance and dividends within the basic rate band, supplemented by employer pension contributions that attract Corporation Tax relief. IR35 and off-payroll working rules require engagers in medium and large private sector organisations to determine employment status of contractors — inside IR35 engagements require PAYE and NI deductions through the fee payer. Sole traders face Class 2 and Class 4 National Insurance on profits plus income tax, while partnerships allocate profits to partners for individual SA104 reporting. We conduct pre year-end reviews covering capital allowance maximisation, pension contribution timing, and profit deferral or acceleration strategies within HMRC anti-avoidance rules including the settlements legislation.
Common Questions
HMRC Investigation & Enquiry Support

HMRC conducts enquiries into Corporation Tax returns (CT600), VAT returns, PAYE records, CIS returns, and Self Assessment returns to verify tax has been correctly calculated and paid. Standard enquiry time limits are four years from the filing deadline, extending to six years where HMRC identifies careless behaviour and 20 years for deliberate non-compliance. Enquiry types range from aspect enquiries targeting specific items to full enquiries reviewing the entire return. We act as your agent with HMRC, compiling requested evidence, preparing technical arguments on disputed points, and negotiating settlements including penalty reductions for unprompted disclosure or reasonable care. Common enquiry triggers include R&D tax credit claims, significant year-on-year profit fluctuations, CIS compliance issues, and MTD VAT discrepancies. Professional representation typically resolves enquiries faster and with lower penalties than unrepresented taxpayers.
