Accountants for IT Contractors
IT contractors on day rates need four things done well: a properly-run Ltd, annual salary/dividend optimisation, substantial pension contributions, and a real IR35 opinion on every new contract. £95/mo covers the lot.
How do you work?
IT contracting is one of the largest freelancer categories in the UK. Day rates typically £500-£1,200, working for banks, insurers, government, consultancies and enterprise clients via agencies and direct. Most IT contractors operate through limited companies with spouse shareholders, and many under-optimise by £3,000-£8,000 a year compared to what their numbers could support.
The gap between a cheap filing-only accountant and a properly-run Ltd isn't sophistication — it's consistency. Annual salary/dividend review. Pension contributions sized correctly. £100k cliff-edge management. IR35 reviews before every new engagement. MVL planning when retirement starts appearing on the horizon. Done routinely each year, these save meaningful money.
Tax questions specific to it contractors.
IR35 on every new contract
Every new engagement needs a 48-hour written IR35 opinion before signing — particularly for enterprise clients running blanket bans. Accountants in our network handle the contract review and SDS challenge support.
Salary/dividend optimisation
£12,570 salary plus dividends is the usual optimum, but spouse shareholding, pension contributions, and the £100k cliff change the calculation. The matched accountant models it annually.
Pension contributions
Employer pension contributions from the Ltd are corporation-tax deductible, carry no income tax or NI, and don't touch your dividend allowance. £20k-£60k/year is a common lever.
The £100k cliff edge
Between £100k and £125,140 of adjusted net income, you lose £1 of personal allowance per £2 of income — a 60% marginal rate. We manage dividend timing and pension contributions to stay below.
Agency vs direct contracts
Contract structure varies — some through agencies, some direct, some via umbrella. Each has different IR35 and tax implications. We untangle the structure at onboarding.
Exit planning
When you wind down — semi-retirement, going permanent, next career — Members' Voluntary Liquidation under Business Asset Disposal Relief often saves £50k+ in tax on retained profits. Plan 12-24 months ahead.
The contractor's annual tax plan, in six lines.
Most of the tax saving in an IT contractor Ltd comes from six annual decisions, run consistently every April.
1. Set the salary
For a single-director Ltd: £12,570 (the personal allowance). For a Ltd with additional employees using the employment allowance: often higher. For a director with significant other income (PAYE role, rental income): sometimes lower.
2. Size the pension contribution
Up to £60,000 per year (tapered down above £200k threshold income). Carry-forward from the last three years is available if you haven't used it. For high-earning contractors, this is usually the single biggest tax lever available.
3. Decide the dividend level
After salary + pension, the remaining drawable amount becomes the dividend envelope. The question is how much to draw this year versus leave in the company for later extraction under lower rates (MVL, gradual drawdown, pension).
4. Spouse shareholder?
If your spouse has unused personal allowance and basic-rate band, splitting dividends can save £2,000-£5,000 a year. Needs genuine share ownership (post-Arctic Systems), handled properly at setup.
5. Review IR35 status
Six-monthly status check on any long-running contract. Working practices can drift, client SDS decisions can change, and early detection of problems is far cheaper than late correction.
6. Update the cashflow plan
Forecast personal tax bills, company tax bills, VAT quarters, and dividend timing for the year ahead. Nothing should be a surprise.

I've been contracting for years through an existing Ltd. Is switching accountants painful?
No. We write to your current accountant with professional clearance, they send records, we pick up. 2-3 weeks end to end, and you're not involved in the handover beyond signing the clearance letter. Cleanest point to switch is between your Ltd's year-end and filing deadline.
What happens if my client insists on an inside-IR35 determination?
You have formal disagreement rights (45-day client response window). We draft the challenge letter citing specific case-law grounds and working-practice evidence. Many clients overturn SDS decisions when challenged properly. If the challenge fails, accountants in our network help you decide whether to accept the contract inside IR35 (via umbrella), look elsewhere, or walk.
Can I put retained profits into investments through the company?
Small surplus cash in a deposit account is fine. Substantial investment activity (property, stocks) turns the Ltd into a Close Investment Company, which complicates Business Asset Disposal Relief on eventual MVL and creates different corporation tax implications. For ongoing investment activity we usually recommend a separate vehicle alongside the trading Ltd.
How do you handle contracts paid via umbrella?
Umbrella payments are PAYE — no Ltd involvement for that contract. You keep your Ltd running for other work. On your personal tax return the umbrella income goes on SA102 and any Ltd dividends go on SA101. We consolidate cleanly at year-end.
What's the best Ltd closure strategy when I retire?
For Ltds with £50k+ retained profit, Members' Voluntary Liquidation (MVL) under Business Asset Disposal Relief almost always wins. Retained profit extracted as capital gains at 14% (from April 2026, up to £1m lifetime) vs 33.75-39.35% dividend tax. Planning needs to start 12-24 months ahead: accounts clean, no income for 2 years before, genuine cessation.
Do you handle clients contracting abroad?
Yes. UK residents are taxed on worldwide income, but foreign tax paid is usually credited via double-taxation treaty relief. For long-term international contracts accountants in our network handle the UK side and coordinate with specialist foreign tax advice where necessary. Short-term international work is straightforward.
