Islington tax returns, prepared by Chartered Certified Accountants

Who needs a Self Assessment tax return in Islington?

In short: anyone in Islington with untaxed income, such as self-employment or rent over £1,000, dividends above £500, foreign income or capital gains, usually needs to file. HMRC can also ask you to file by sending a notice.

As an Islington accountant, we see a borough of contrasts: Upper Street hospitality owners, Clerkenwell designers, long-standing homeowners in Canonbury who now let a basement flat, and young professionals near Angel with bonuses and share schemes. Our job is to turn all of that into an accurate return that claims every relief.

Common reasons HMRC needs a tax return

• Profits from freelance or self-employed work
• Rent from a flat, house or room, above the £1,000 property allowance
• Dividends from your own company or shares
• Gains on property, shares or crypto
• Income from overseas savings, property or pensions
• The High Income Child Benefit Charge
• A letter from HMRC asking you to file

Self-employed tax returns in Islington

Clerkenwell and the area around Old Street are packed with independent design, tech and media businesses. We prepare self-employed returns that claim equipment, software, studio or desk rent, travel to clients and a share of home running costs. See self-employed accountants and add bookkeeping if you would like records kept for you.

Landlord tax returns in Islington

Many Islington homeowners let a flat after moving out of London or let part of a large period property. We report rental income, claim agent fees, repairs and service charges, and handle joint ownership with a spouse. Mortgage interest relief is a 20% tax credit, rising to 22% from April 2027 when property income gets its own 22%, 42% and 47% rates.

Renting out your Islington home after moving

A common Islington situation is keeping your flat when you move elsewhere and letting it out. Rent becomes taxable, you may need Making Tax Digital as income grows, and when you eventually sell, Private Residence Relief and the 60-day Capital Gains Tax return both come into play. We plan for all of it from the first year of letting.

Partnership tax returns

If you run a business with someone else, the partnership files an SA800 and every partner reports their share. We handle the whole set, together. See partnership tax returns.

Capital Gains Tax reporting

Sold a flat, shares or an inherited property? Gains over £3,000 are taxable at 18% or 24%, and residential property sales have a separate 60-day reporting deadline. Our Capital Gains Tax team handles both returns.

Foreign income reporting

Savings, rent or pensions from abroad usually belong on the foreign pages of your return, with relief for overseas tax. If past years were missed, our WDF service sorts it out.

Crypto tax reporting

Crypto is taxed as property in the UK. We calculate gains using same-day, 30-day and Section 104 rules and complete the crypto boxes on your return. More on our crypto page.
