I still remember the first January after I went fully freelance. The tax bill landed and it felt like someone had quietly emptied half my bank account overnight. Payments on account had turned a manageable liability into something that stung for months. So when the new chancellor slipped a line about reforming that system into the Autumn Budget, I sat up a little straighter. The promise of smaller, more regular payments from 2029 sounds almost too sensible. But after years of watching freelancers scramble every January and July, I keep asking the same question: will these self assessment tax reforms actually fix the real problem?
Understanding The Current Payments On Account System
Most people outside the self-employed world have never heard of payments on account. Inside it, the phrase can trigger a quiet groan. Right now, if you owe more than £1,000 through self assessment and less than 80 percent of your tax has already been collected via a tax code, HMRC expects you to pay roughly half of next year’s bill in advance.
That advance payment is split into two equal chunks. One lands with your balancing payment on 31 January. The second is due by 31 July. The amounts are based entirely on what you owed the previous year. In practice this means you are often paying tax on money you have not yet earned, or worse, on money clients still have not paid you.
Take a simple example. Suppose your tax bill for 2025/26 came to £3,000. On 31 January 2027 you would face £4,500 in total: the £3,000 balancing payment plus the first £1,500 payment on account toward 2026/27. Another £1,500 would then be due the following July. If your income drops, you can apply to reduce the payments, but the process is not automatic and underestimating carries interest risk.
Accountants often argue the system is fair if you are organised. In theory you have from April until January to prepare for the first big hit and another six months for the second. In reality many of us are busy chasing invoices, delivering work and trying to keep a business alive. The large twice-yearly demands still create genuine cashflow stress.
Why The System Feels Broken For Freelancers
The core issue is not the existence of advance payments. It is the rigid assumption that last year’s income will look roughly like this year’s. Freelance earnings rarely work that way. One big project can inflate a year’s figures. The next year might be quieter. Clients pay late. Contracts end suddenly. Yet the payments on account calculation does not care.
Late payment penalties start at 5 percent after 30 days and interest currently sits around 7.75 percent from the day after the due date. That combination turns a cashflow squeeze into an expensive problem fast. I have spoken to plenty of self-employed people who end up using credit cards or short-term loans simply to clear the January bill. That is not efficient tax planning. It is survival.
You can of course request a reduction if you expect lower profits. HMRC will usually agree if the figures look reasonable. But the burden sits entirely on the taxpayer to notice the change, calculate a new figure and submit the request in time. Miss that step and the original higher amounts stand.
What The Chancellor Actually Announced
In the Autumn Budget the new chancellor confirmed that the government will reform the administration of self-assessment income tax from April 2029. The key phrase was “smaller, more regular payments instead of facing large bills that are often harder to pay.”
Consultation on the changes has been running since late 2025. The direction of travel is clear: move away from the two large lump sums and toward a system of more frequent, smaller automatic payments spread through the year. These will still be calculated using the previous year’s liability, but the payment pattern itself will change.
HMRC has also promised improved online tools and app support so taxpayers can estimate liabilities, make voluntary advance payments and track progress against a forecasted bill. In theory this should reduce the shock factor that currently hits every January and July.
Importantly, payments on account are not disappearing. The mechanism remains. Only the timing and size of the individual transfers will alter. Anyone currently required to make them will still do so, just in a different rhythm.
How The New System Is Expected To Work
Exact frequency has not been finalised. Monthly or quarterly instalments both appear possible. The government has stressed that the total tax collected will stay the same. The difference is purely cashflow timing for the taxpayer.
From April 2029, self-employed individuals and others caught by the rules should be able to see a running balance of tax already paid against the projected annual liability. Voluntary top-ups will remain available for those who prefer to stay ahead. The hope is that smaller automatic amounts feel less painful and reduce the number of people who simply forget or cannot find the cash when the big deadlines arrive.
One practical advantage already visible is psychological. Spreading the cost makes the liability feel more like a regular business overhead and less like an unexpected demand. For those who currently struggle to put money aside, automatic collection throughout the year may prove helpful.
It’s a good change, but payments on account aren’t on the way out – it’s the big twice-yearly payments in January and July that are going. From April 2029, anyone who makes payments on account will pay smaller, automatic amounts during the year, still based on last year’s tax.
That assessment from a working accountant captures the limited but real nature of the reform. The underlying calculation method stays. Only the payment schedule softens.
The Cashflow Problem That Still Remains
Here is the part that leaves me less than fully convinced. Smaller payments help with budgeting discipline, yet they do nothing to solve the deeper issue of unpredictable income. If a client pays late or a contract ends, the money for even a modest monthly tax payment may simply not be sitting in the account.
The system still assumes continuity of earnings. It still takes money based on a previous year that may bear little resemblance to the current one. Making the deductions more frequent does not create cash that is not there. It merely reduces the size of each individual shortfall.
In my experience the freelancers who already set money aside carefully will adapt easily. Those who live closer to the edge may find that regular smaller hits still disrupt day-to-day operations, just more often. The reform improves the payment experience. It does not redesign the fundamental mismatch between fixed advance demands and variable self-employed income.
Transition Year Risks Worth Watching
Accountants are already flagging a specific danger around the changeover. In the year the new system begins, the final payments under the old rules are likely to overlap with the first instalments of the new schedule. Anyone who has not planned carefully could face an unusually heavy combined burden.
The practical advice is straightforward: start building a larger tax reserve well before 2029. Treat the transition year as a one-off spike rather than business as usual. Those who leave it until the last moment may find the overlap creates exactly the kind of large bill the reform was supposed to eliminate.
None of the detail is yet law. Frequency, exact start mechanisms and any transitional relief still need final design. Until the legislation appears, the safest stance is cautious preparation rather than assumption that everything will feel easier overnight.
Practical Steps Self-Employed People Can Take Now
Even with the reforms years away, sensible habits remain useful. Open a separate savings account and transfer a percentage of every invoice as soon as it clears. Review your payments on account each spring and apply for a reduction promptly if profits look lower. Keep records clean so that any future online tools can give accurate forecasts.
Many freelancers also benefit from speaking to an accountant before the January deadline rather than after. A short conversation in November can surface options that disappear once the bill is due. Interest and penalties are avoidable costs. Early action usually costs less than late reaction.
Looking further ahead, the promised digital tools could make voluntary payments simpler. Anyone who prefers to stay ahead of the liability may find the new interface encourages better habits. Those who currently ignore the issue until the brown envelope arrives will still need to change behaviour, regardless of payment frequency.
Who Benefits Most From The Changes
People who already struggle to save for large tax bills stand to gain the most. High-turnover traders who see constant cash movement but thin margins often underestimate the eventual profit. Automatic smaller deductions throughout the year can act as a form of enforced discipline.
Steady earners with predictable income will notice less dramatic improvement, yet they should still find the psychological load lighter. The January cliff-edge effect softens for almost everyone. That alone has value.
Those with highly volatile income remain the group least helped. For them the core problem was never the size of each payment. It was the mismatch between the calculation base and actual current earnings. Until the system becomes more responsive to real-time income, that group will continue to need active management rather than passive reliance on the new schedule.
Broader Context Of Self Assessment Modernisation
The payments on account reform sits inside a wider push to update self assessment. Making Tax Digital has already changed how many businesses keep records. The direction is toward continuous digital reporting and more frequent interaction with HMRC systems. Smaller regular tax payments fit that pattern.
Whether the overall experience improves depends heavily on the quality of the new tools. A clunky interface that still requires manual calculations will frustrate users. A clear, mobile-friendly system that shows a live running balance could genuinely change behaviour. We will not know which version arrives until closer to 2029.
I have found that policy announcements often sound more transformative than the eventual implementation. The chancellor’s language was carefully positive. The practical detail will determine whether freelancers feel the difference in their day-to-day finances.
Balancing The Benefits Against Remaining Gaps
On balance the reform is welcome. Removing the two large cliff-edge payments reduces a genuine source of stress. More regular instalments should help people budget and reduce the number of late payment penalties. Improved digital tools, if delivered well, add further value.
Yet the changes stop short of addressing the fundamental cashflow mismatch that defines self-employed life. Income arrives unevenly. Tax demands remain linked to a previous year. Spreading the same total across more dates softens the impact without removing the underlying tension.
Perhaps the most interesting aspect is how little the announcement focused on this point. The political messaging centred on fairness and ease of payment. The lived experience of irregular earnings received less attention. That gap between policy language and practical reality is worth watching as the detailed rules emerge.
For now the sensible response is preparation rather than celebration. Keep setting money aside. Review your current payments on account each year. Watch for the detailed consultation outcomes and the eventual legislation. And remember that even after 2029 the responsibility for having the cash available will still sit with the taxpayer, not the payment schedule.
The taxman may finally be showing a little more understanding of self-employed life. Whether that understanding goes far enough remains an open question. The answer will become clearer once the smaller regular payments actually start leaving accounts in 2029. Until then, treating the reform as a helpful improvement rather than a complete solution seems the most realistic stance.
Self-employed people who approach the next few years with clear eyes and disciplined reserves will be best placed to benefit from whatever final shape the system takes. Those who wait for the new rules to solve their cashflow problems may discover that the fundamental challenges of irregular income have simply found a new rhythm.
In the end the reform changes the timing of the pain more than it removes the pain itself. For many that will still feel like progress. For others it will feel like a missed opportunity to redesign a system that has long sat awkwardly alongside the realities of freelance and small business life. Time, and the detailed rules still to come, will show which group is right.
Until then the best advice remains the oldest: put money aside when the invoice clears, review the numbers regularly, and never assume that last year’s figures will magically match this year’s bank balance. The payments may get smaller and more frequent. The need for personal financial discipline will not.
