Your Comprehensive Guide to Self Assessment Tax Returns in California
Self Assessment Tax Returns in California are a legal requirement for many individuals, including sole traders, landlords, and those with additional income sources. The process involves completing an SA100 form and submitting it to HMRC, detailing all your taxable income and allowable expenses.

Frequently Asked Questions
Everything you need to know about limited company accounting.
You typically need to file a Self Assessment Tax Return in California if you are self-employed, a landlord with rental income, or have other untaxed income such as dividends, savings interest, or foreign income. Also, if you earn over £100,000 or need to pay Capital Gains Tax, you must register. Our accountants can help you determine your obligations.
Our service includes full preparation and filing of your SA100 return, calculation of your tax liability, identification of allowable expenses and reliefs, and submission to HMRC. We also handle all correspondence with HMRC on your behalf, including any queries or investigations.
First, you provide us with your income and expense details via our secure online portal. Our accountants then prepare your SA100, ensuring accuracy and compliance. You review and approve the return, and we submit it electronically to HMRC, well before the deadline.
You'll need to provide evidence of all income, such as P60s, P45s, bank interest statements, dividend vouchers, rental income records, and details of any self-employment income and expenses. Also, include any pension contributions or charitable donations for tax relief.
Once you authorise us as your agent, we register with HMRC using your unique taxpayer reference (UTR). This allows us to act on your behalf, submit returns, and handle communications. We manage the entire registration process for you.
If you miss the deadline, HMRC imposes automatic late-filing penalties, which increase over time. SATR ensures this doesn't happen by submitting your return well ahead of the deadline. We also offer support if you have already missed a deadline to minimise penalties.
We offer transparent fixed-fee packages with no hidden costs. The fee depends on the complexity of your tax affairs, such as the number of income sources. You'll always know the cost upfront, and we'll never surprise you with extra charges.
